Liquid-cooling tube, also known as cooling serpentine tube, is a heat exchange component commonly used in cylindrical batteries. The liquid-cooling tube uses a unique hollow structure pipe and is developed with high precision manufacturing quality. It has a large inner surface area can achieve more efficient heat conduction, so it is often used in battery packs with cylindrical cells. As we all know, high temperature is the invisible killer of electronic components, integrated circuits, etc. High temperature will not only shorten the service life of the equipment, cause unstable system operation, and even cause problems such as component burnout. Therefore, heat dissipation treatment of electronic components and integrated circuits cannot be ignored. There are many types of heat dissipation methods, such as liquid cooling, air cooling, and evaporator air cooling. Among these heat dissipation methods, liquid cooling stands out for its excellent heat dissipation efficiency, low space occupation and silent characteristics, and has been widely used. Liquid cooling devices usually use pumps to circulate the coolant in the liquid cooling tube and dissipate heat. Therefore, the liquid-cooling tube is an important part of the liquid cooling device. It can not only serve as a channel for the coolant to flow without contacting the heating element, but it can also serve as a heat transfer pipe, directly in contact with the heating element, absorbing the heat of the heating element and transferring the heat to the coolant. Normally, when a liquid-cooling tube doubles as a heat transfer pipe, you can generally change the material of the liquid-cooling tube, the composition of the coolant, and increase the contact area between the liquid-cooling tube and the heating element, the flow rate of the coolant in the liquid-cooling tube, etc. method to enhance the heat dissipation effect of the liquid cooling device. Liquid-cooling tubes are usually made of aluminum, copper alloy or a combination of the two. In terms of thermal conductivity, there are other materials that have better thermal conductivity than copper and aluminum alloys, such as silver, but silver is more expensive, so it is generally Silver is not used for liquid cooling tubes. The selection of materials for liquid-cooling tubes is determined by factors such as the material's price, processing difficulty, weight, hardness, and usage environment. It cannot just look at the thermal conductivity of the material. Therefore, changing the material of the liquid cooling tube to enhance the heat dissipation effect of the liquid cooling device has certain limitations. In the same way, the selection of coolant components is also determined by the price of the coolant, specific heat capacity, heat absorption capacity, usage environment and other factors. Therefore, changing the composition of the coolant to enhance the heat dissipation effect of the liquid cooling device also has certain limitations. Increasing the contact area between the liquid-cooling tube and the heating element will correspondingly increase the space occupied by the liquid cooling tube within the system, resulting in a reduction in the space utilization within the system. In addition, increasing the contact area between the liquid-cooling tube and the heating element also has many problems such as complicated design and increased cost The flow rate of coolant in the liquid-cooling tube is related to the density, viscosity of the coolant and the power of the pump. Among them, the power of the pump is the main factor that determines the flow rate of the coolant in the liquid-cooling tube. Generally speaking, the greater the power of the pump, the greater the flow rate of the coolant in the liquid cooling tube. As the power of the pump increases, the working energy consumption of the pump will also increase, the power consumption will increase, and the cost will increase. At the same time, as the power of the pump increases, the requirements for the pump will also increase, and the cost of the pump will also increase

Recently, it has been reported that Chinese electric vehicle manufacturer BYD's plan to build a factory in India has been canceled. This news has garnered widespread attention and speculation in the industry. It is understood that BYD originally planned to invest around $2 billion in India to establish a large-scale electric vehicle manufacturing plant to meet the country's demand for electric vehicles. However, due to a series of reasons, BYD has decided to cancel this plan. Firstly, the Indian government's policies are not supportive enough of the development of the electric vehicle industry. Despite the Indian government's promotion of electric vehicles, the support in terms of infrastructure and subsidy policies is not strong enough, which has raised doubts about the investment prospects of building a factory in India for BYD. Secondly, the demand for electric vehicles in the Indian market is not strong. Despite being the second most populous country in the world, the sales of electric vehicles in India have been low. According to statistics, electric vehicle sales in India only account for 1% of the overall automobile sales, which has raised concerns about the return on investment for BYD in building a factory in India. In addition, competition from domestic electric vehicle manufacturers in India is also one of the reasons for BYD's cancellation of the plan. Indian domestic companies such as Tata Motors and Mahindra & Mahindra have achieved certain achievements in the field of electric vehicles. Compared to international brands, domestic companies have certain advantages in terms of brand recognition and sales network, which has put BYD in fierce competition in the Indian market. Opinions on BYD's cancellation of the plan to build a factory in India are divided in the industry. Some believe that BYD's decision is wise because the demand for electric vehicles in the Indian market is not strong and the return on investment is unclear. Canceling the plan can avoid losses. Others believe that BYD should should continue to push forward with the plan to build a factory in India because electric vehicles are the future trend. Although the current demand in the Indian market is not high, with the improvement of government policies and the increase in consumer environmental awareness, there is huge market potential. For BYD, canceling the plan to build a factory in India may have a certain impact on its development in the Indian market. Currently, BYD mainly sells electric buses and electric taxis in the Indian market, and these models have maintained a high growth momentum in sales. However, if BYD cannot establish a production base in India, it will face higher import costs and competition pressure. Overall, the news of BYD canceling the plan to build a factory in India has sparked heated discussions in the industry. Whether in support or opposition, this decision will have a certain impact on BYD's development in the Indian market. It is worth paying attention to how BYD will respond to this challenge in the future. #Heat Exchange,Aluminum Water Cooling Plate for EV,Snake Tube for ESS,Cooling Pipe#

From 14 to 16 June, CATL presented its newly upgraded all-scene energy storage solutions at EES Europe. It is reported that the exhibition attracted nearly 100 head enterprises to visit the booth for in-depth negotiation to sign and lock in more than 40GWh cooperation agreement. It is reported that CATL's EnerC Plus, the world's first transportation-integrated standard 20-foot container-type liquid-cooled energy storage system, was officially unveiled, which is equipped with CATL's new generation 306Ah battery cells, which can achieve 20 years of safe and reliable operation with a 10% increase in battery power and a back-to-back layout design that saves over 28% of floor space. In addition, CATL's family of high-safety, long-life advanced energy storage cells also made their debut at the exhibition, with battery specifications including 280Ah, 285Ah and 306Ah. Trumony specialises in energy storage liquid cooling solutions, with customised 1865, 2170, 4680 and various battery pack liquid cooling systems.

High-power IGBT heat dissipation looks towards liquid cooling The insulated gate bipolar transistor (IGBT) is a key component in new energy conversion systems and high-voltage power switching devices, and is a representative platform device in high-power semiconductors. As a core functional device of a power electronic control circuit with high heat flow density, most of the failures of IGBT modules are related to thermal faults. The accumulation of heat can seriously affect the working condition and performance of the device, and if the temperature is too high (150°C), it can also pose a serious threat to the normal operation of the whole system module, or even damage it. Therefore, it is important to do effective thermal detection and management of IGBTs. Trumony has professional technical and design engineers who are able to design efficient, stable, compact and lightweight liquid-cooled heat transfer solutions for different IGBT projects. There are currently two types of IGBT heat dissipation: passive heat dissipation (heat dissipation by natural convection, which dissipates heat into the atmosphere without external forces) and active heat dissipation (such as air or water cooling). Passive heat dissipation includes Fin cooling: the heat generated by the IGBT will be dissipated by natural convection through the fins of the heat sink; Heat pipe cooling technology: heat pipes as two-phase heat transfer devices, with low heat transfer temperature difference, high heat transfer performance, high effective thermal conductivity advantages, simple working principle, no mechanical maintenance, purely simple and easy to operate passive method. (If fins are embedded, the efficiency of the heat dissipation will be increased even more) Phase Change Material (PCM) based heat dissipation: A new type of material that uses the release or absorption of latent heat during a phase change to control heat transfer. Active heat dissipation can effectively increase the cooling efficiency of a heat sink by 1 to 2 energy levels, and the cooling speed is faster, as the heat is dissipated by external forces. However, the appropriate heat dissipation method should be chosen for different use scenarios. Active cooling includes Air-cooled cooling technology: to provide sufficient cooling for IGBT cooling needs with high power and heat flux, measures to strengthen air-cooled cooling are mainly to increase the heat dissipation area, improve the heat transfer coefficient and rational design of air ducts, which are related to heat sink material, structure, airfoil, etc. Compared to natural cooling, forced air cooling can increase heat dissipation by a factor of 5 to 12. However, it is important to note that forced air cooling requires the configuration of fans and air ducts, which may generate a high level of noise. Liquid cooling technology: When the power of the equipment is very large (under the megavolt-ampere level), the forced air cooling technology cannot meet the higher cooling requirements due to the restrictions of the air ducts, air pressure and noise indicators, etc., water cooling is a good choice, and the cooling coefficient of the liquid cooling plate is about 100-300 times that of natural air cooling. Sometimes oil-cooled cooling is used in high voltage and high power power electronic devices due to insulation requirements.

After the rapid development in recent years, China has now become the world's number one country in terms of production and sales of new energy vehicles. With the introduction of the national subsidy policy for new energy vehicles in 2019 and the increase in range requirements, higher requirements for the energy density of the battery system have been put forward. There are two paths to improve the energy density of the battery: one is to increase the specific energy of the single cell; the other is to lighten the structure of the battery pack. To increase the specific energy of a single cell is technically difficult, with long R&D cycles and large capital investment, while making the structure of the battery pack lighter is easier to achieve. The use of aluminium alloys in automobiles has been commonplace for a long time. Aluminium has many advantages such as low density, high specific strength, thermal stability, corrosion resistance and good thermal conductivity, non-magnetic, easy to shape and high recycling value, making it an ideal material for lightweight battery pack design. At present, the mainstream scheme for battery pack shell materials is extruded aluminium alloy shell + PP/glass fibre composite top cover. From the point of view of current developments, the aluminium alloy shell and plastic top cover solution has the prospect of lightweighting. The aluminium extrusion profile + stir friction welding + MIG welding solution is used for the housing, which has a low overall application cost, meets the performance requirements and enables the integration of the circulating waterway for water-cooled batteries. The top cover uses a non-metallic top cover, mainly using PP/glass fibre + LFT-D moulding process, which can improve the efficiency of production and also meet the requirements of flame burning and sealing performance, and the mould cost is low. Aluminium alloy battery pack housings have been used in a number of new energy vehicles, such as the BYD Song and Tang, the Azera ES8 and the BAIC EV series. The housing can improve the energy density of the battery pack and increase the range. This shows that aluminium alloy battery pack shells have a broad market prospect.

A milestone breakthrough! --Condensed Battery The introduction of CATL's 'Condensed Battery' will greatly promote the further development of battery technology and is expected to be widely used in new energy vehicles, energy storage, aviation and other fields in the future, further enhancing China's position and competitiveness in the global new energy industry, which is a major innovation that has been in the making for a long time, but also a It is a milestone breakthrough that is future-proof and fully meets the all-round requirements of electrification. With the gradual maturation of lithium-ion battery technology, its energy density is approaching its theoretical limit. This means that the traditional battery upgrade route faces many technical and manufacturing challenges. To meet full electrification and carbon neutrality targets, the industry urgently needs more advanced electrochemical material systems to achieve breakthroughs in higher energy densities. Of course, higher energy densities also mean greater risks and challenges, such as higher demands on battery safety. Therefore, the search for more advanced electrochemical material systems is the core crux of battery technology to achieve new breakthroughs. This new condensed battery is an innovation using solid-state battery technology, the core technology of which is the design and manufacture of condensed electrolytes. Traditional lithium-ion batteries use liquid electrolytes, which are flawed by the need to withstand extreme operating conditions such as high temperature and pressure and violent impacts within a short period of time, easily causing safety problems such as leakage and combustion. The condensed electrolyte, on the other hand, is a new type of electrolyte developed by CATL - high power bionic condensed electrolyte, which is a combination of various functional materials, with a combination of organic and inorganic materials, organic surface coating covered with inorganic raw materials, thus forming a fast ion conduction condensed electrolyte, which is non-flammable, zero volatile and This significantly improves the thermal stability of the battery, while regulating inter-chain interactions through the construction of a micron-level adaptive mesh structure, which enhances microstructural stability while improving battery kinetics and lithium ion transport efficiency. This condensed electrolyte produces a battery with the advantages of good safety, high energy density and low self-discharge rate. Specifically, it is safer in that the internal material is in a solid polymer and there is no liquid electrolyte that is prone to leakage. Secondly, the current of a condensed battery is more stable, its self-discharge rate is low, and its service life is longer, with higher energy density and better environmental adaptability." Future industrial innovation must collaborate across borders, break boundaries and develop comprehensively. CATL's condensed batteries are its latest innovation and an important milestone in its zero-carbon strategy, driving the next round of innovation. This innovation is not limited to one segment, but spans the entire industry and drives overall innovation.

Five ways to keep power batteries out of thermal runaway! Thermal runaway means that the battery generates a large amount of heat during operation and the temperature rises rapidly beyond the safety range, thus causing a fire or explosion. As one of the core components of a new energy vehicle, the power battery provides electricity to ensure the normal operation of the electric vehicle, and whether it can be kept away from thermal runaway directly affects the safety, service life, charge and discharge times of the power battery. How to keep the battery away from thermal runaway is a common concern of new energy vehicle users. To this end, TRUMONY has compiled the following methods to ensure the safety of the power battery and avoid thermal runaway from happening. 1. Adopt liquid cooling technology The liquid cooling system can be highly integrated with the battery pack, easy to install on site, occupying a small area, without worrying about dust, water vapour condensation and other problems. In the event of a thermal runaway, liquid cooling solutions can rely on a high flow of cooling media to force the battery pack to dissipate heat and redistribute heat between battery modules, which can quickly inhibit the continuous deterioration of thermal runaway and reduce the risk of runaway. Liquid-cooled panels, which are more commonly used in new energy vehicles, work by transferring excess heat generated by battery operation through contact with the surface of the plate type aluminium device. The liquid-cooled system uses the large heat transfer coefficient of liquid flow to transfer high levels of heat, which is eventually carried away by the coolant passing through the internal flow channels of the device. 2. Battery Management System A battery management system (BMS) is a system that monitors the status of the battery. It monitors parameters such as temperature, voltage, current and capacity of the battery and ensures its safety by controlling its operating status. 3. Protection measures In addition to controlling the temperature of the battery and using the BMS, other protective measures are required to ensure the safety of the battery. For example, guards can be placed around the battery to prevent it from colliding with other objects. Guards can also be installed to avoid short-circuiting and overcharging of the battery. 4. Choose a high-quality battery It is advisable to buy original chargers and batteries as these products have undergone rigorous testing and verification and are of safer and more reliable quality. Moreover, due to the complex internal structure of lithium batteries, if you are not a professional, do not dismantle the batteries at will to avoid damaging them and causing safety accidents. But the use of good quality batteries, but also only passive protection, and can actively protect the safety of the driver, the current stage or driving safety awareness, "safe driving" "active defensive driving" is the most important line of defence to protect the safety of drivers and passengers. 5. Correct use of batteries When using power batteries, there are some basic rules to follow. For example, avoid leaving batteries in hot or cold environments for long periods of time, avoid contact with water or other liquids, avoid charging and discharging batteries in hot or humid environments and do not overcharge them. The battery's charge level and state of charge should be checked regularly for wear and tear, damage or other abnormalities. If abnormalities are found, you should contact the manufacturer or a professional repairer for repair or replacement in order to avoid accidents. It is also very important to carry out regular maintenance on the power battery, which needs to be replaced in time for ageing. Translated with DeepL

The automotive stamping process is one of the most important and time-consuming steps in automotive manufacturing. The automobile mainframe includes four major processes: stamping, welding, coating and general. Among them, the stamping process can be basically divided into the parts of drawing, punching, trimming and shaping. Depending on the structural characteristics and complexity of different parts as well as the process characteristics of the vehicle company, the forming process varies from 4 to 6 course sequences. With the continuous development of the automotive industry, the stamping process is also being optimised and upgraded. Firstly, there is automation. Automation in the form of robots, automated guided vehicles and other machines will reduce the need for manual labour, resulting in faster production, more precision and fewer errors, and a better grasp of precision and quality throughout the stamping process. At present, the stamping line with the highest production speed is the German servo press line, with a continuous production speed of up to 17 times/minute for the whole line, while the domestic Jiji line can also reach 13 times/minute, which means lower production costs and higher profits. So 17 times/minute is certainly not the limit, and the future will certainly be towards higher production efficiency. At the same time, as consumers' personalisation needs become stronger and stronger, model changes are becoming more and more frequent, so the future of mould flexibility. Low cost is the main direction of development in the future. In addition, the speed and efficiency of stamping processes will increase in the future. new technologies such as 3D printing and laser cutting will enable more precise and faster production, less scrap consumption and, above all, greater flexibility, meaning that moulds can be dispensed with and individualised. This will allow manufacturers to produce parts quickly, reducing waiting times and enabling faster turnaround times. In addition, advances in computer-aided design (CAD) and computer-aided manufacturing (CAM) software will make the design process faster and more accurate. This will help to reduce errors, thus saving time and money. Not only that, but the emergence of disruptive technologies has also inspired the stamping process. Carbon fibre bodies and wheels are already being used on high-end luxury cars, which in itself is a material change from the usual sheet steel and aluminium, and so the forming process is moving beyond stamping.

Power packs are the only source of power for purely electric vehicles and the range that an electric vehicle can travel depends on the power of the pack. The market is using high capacity cells or using more cells as a way of boosting the power pack electrical energy, however this can drive up the cost of the pack, so the focus needs to be on optimising the structure of the pack during the design process of the power battery, so what are the main components of an EV power pack? 1. Power Cell Module The role of the power battery module in the power pack is to store and release energy, which is the power source of the electric vehicle. The power battery module can be understood as the power battery monomer combined into multiple PACKs through series-parallel connection, PACK is a single component, which means packaging, encapsulation and assembly, and its process procedure includes three major parts: processing, assembly and packaging. After the power battery module has been structurally designed, it can be combined with the power battery management system and thermal management system to form a more complete power battery pack. The power battery pack is designed in a fixed position with the help of technology and structure, and together they play the function of electrical energy charging and storage. The fundamental role of the module is to fix, connect and secure the pack. Power battery cells and batteries are divided by positive materials, including lithium cobaltate, lithium manganate, lithium iron phosphate and lithium nickel cobalt manganate ternary materials. The structure of the power battery module should be fixed, supported and protected by the battery cells, which can be summarised into 4 major items: mechanical strength, electrical performance, thermal performance and fault handling capability. Power battery modules can be divided into three types according to the structural shape of the cells: cylindrical cells, square cells and soft packs, whose respective advantages and disadvantages are also obvious. To a large extent, the performance of the cells determines the performance of the power cell module, which in turn affects the performance of the entire power pack. Therefore, when designing a power pack, the material and shape of the cells must be considered in accordance with the design requirements of the vehicle. The ability of the power battery module to hold the cell in place and avoid performance-damaging deformation, to meet current-carrying performance requirements, to control the temperature of the cell, to cut off power in the event of a serious abnormality and to avoid the spread of thermal runaway are all criteria for assessing the merits of the power battery module. 2. Structural System The structural system includes the power battery PACK cover, tray, various metal brackets, end plates and bolts, which can be regarded as the "skeleton" of the power battery PACK, playing the role of support, resistance to mechanical shock, mechanical vibration and environmental protection (waterproof and dustproof). The power battery pack is loaded on the electric vehicle, the mechanical characteristics must be fully considered first, the product must have a certain strength and stiffness, in order to avoid deformation and functional abnormalities under mechanical loads such as vibration and shock, safety protection against collision, extrusion, tumbling, falling and other accident conditions. 3. Electrical System The electrical system mainly consists of high-voltage jumper or high-voltage harness, low-voltage harness and relays. The high-voltage harness can be regarded as the "artery and blood vessel" of the power battery PACK, which continuously transports the power from the heart of the power pack to each required component. The low-voltage harness can be seen as the "neural network" of the power pack, transmitting detection and control signals in real time.

CIBF2023 will have an exhibition area of 240,000 square meters (12 halls).

Definition of Simulation. Finite Element Analysis (FEA) uses mathematical approximation to simulate real physical systems (product models, loads, working conditions). It decomposes the model into a limited number of interconnected sub-regions, namely units, and uses a limited number of units to approximate the real system, and simplifies the original complex system to obtain an approximate solution that can meet the requirements of engineering applications and scientific research. How simulation works in product development A product, from conceptual representation to drawings, models, to the actual product landing, needs to consider a variety of different materials, numerous production processes, or simple or complex production processes. The transition from unstable samples to stable and reliable batch products that can adapt to production changes requires a large number of tests and verifications that meet design parameters. Design and selection of materials, manufacturing and processing, testing and verification, each stage is accompanied by the consumption of time, manpower and material resource. The simulation can test the performance of the product under different conditions by modeling the product model, loading different material parameters and environmental conditions. The product materials required for actual production, the production process of actual operation, and one or more experiments, which are originally in reality, are moved to the computer in a simulated way, and after simulation, we will get the required data result. Through the simulation-aided design and development, the pre-design of the product can be effectively demonstrated, and the loss caused by the design error can be avoided. Simulation can guide design and experiments, so that customers can save the cost of design and development and improve the efficiency of design and development. The applications of simulation Commercial software companies have developed software and computing platforms for different disciplines and industries in combination with different professional characteristics and industry standards of various industries, so as to meet the needs of various industries for simulation computing. At present, there are many kinds of main finite element software. The commonly used simulation software in the automotive industry includes ANSYS series products, HyperWorks series products, MSC series products, and Abaqus software. From the stage of simulation analysis, HyperMesh and ANSA lamps are relatively easy to use preprocessing tools, ANSYS, Nastran, and Abaqus are commonly used solver tools, and HyperView is a commonly used postprocessing software, which is compatible with most of the results file format. In terms of simulation types, Abaqus, Marc, ANSYS, and Nastran are good at solving the structural implicit linear and nonlinear problems of the system. Among them, Abaqus has the most powerful nonlinear solving function. LS-Dyna, Radioss, etc. are commonly used explicit nonlinear analysis software, which are often used to solve large deformation problems such as impact, collision, extrusion, and drop. Fluent, CFX, Star-ccm+, etc. are good at solving fluid mechanics problems in various occasions. How simulation simulation works in Battery pack thermal management The design of EV battery pack needs to ensure that the battery is always in a relatively comfortable temperature environment (battery temperature range 15~40℃; temperature difference between batteries: 5~10℃), so as to ensure long working life and good battery life of the whole vehicle Mileage performance, good work efficiency performance, convenient and fast charging series. In the pack design, the thermal management system design of the pack is completed with the help of thermal fluid simulation analysis. In the system design stage, thermal field simulation analysis can be performed on the pack, module or battery, and the appropriate cooling, heating and thermal insulation methods can be quickly selected according to the simulation results. In the cooling subsystem design stage, thermal field and flow field simulation analysis can be performed on the pack, module or battery. According to the simulation results, parameters such as cooling channel design, cooling medium, cooling inlet temperature and flow rate can be determined. With the help of simulation analysis, a large number of Pack thermal management design and part of the test work can be completed on the computer. A large number of design, manufacturing and testing work are optimized and omitted, and the design cost is also greatly reduced. What TRUMONY can provide?
