The Latest Materials For Solving Leaks in New Energy Vehicle Liquid Cooling Systems
With the continuous improvement of the energy density and fast charging power of new energy vehicle batteries, the liquid cooling thermal management system has become a key component responsible for dissipating heat from the battery pack, the motor, and the on-board charger, ensuring the normal operation of the battery.
However, behind the rapid development of the industry, the reliability issues of the liquid cooling system have become increasingly prominent. According to industry after-sales data feedback, among the failure cases of the liquid cooling system, over 60% are caused by pipeline leakage, rather than the cold plate or pump unit itself. This problem is now becoming a focus of attention for both manufacturers and consumers.
Currently, a large number of vehicle models still use rubber, nylon or aluminum piping. The non-metallic piping, which comes into long-term contact with the ethylene glycol coolant, is prone to aging and cracking under the cold and hot cycles ranging from -30℃ to 80℃. Moreover, the chassis vibration is likely to cause the joints to loosen or develop micro-cracks. For aluminum pipes, they are susceptible to chloride ion pitting and perforation in coastal and de-icing agent environments.
If the coolant seeps into the battery pack or high-voltage electronic control unit, it can cause minor issues such as reduced range and BMS abnormalities, or even serious problems like short circuits and thermal runaway. For automakers, the cost of large-scale recalls caused by this is extremely high. Therefore, upgrading from the material source and selecting materials with more stable physical properties and stronger chemical inertness is the best solution to eliminate liquid cooling leakage.
In response to this market demand, China Super Tech Co., Ltd., leveraging its profound technical expertise and keen market insight, is committed to becoming a trusted partner for stainless steel liquid cooling tubes for global customers. We focus on the fields of new energy vehicles, energy storage, and industrial liquid cooling, and our main products are the best solutions available to address this issue at present: 316 stainless steel liquid cooling tubes and 304 stainless steel liquid cooling tubes.
Among them, the Super Tech 304 stainless steel liquid cooling tube, with its excellent corrosion resistance and high cost-effectiveness, has become the ideal choice for the cooling circuits of power batteries, the cooling water jackets of motors, and the liquid cooling systems for energy storage. It can withstand a wide temperature range of -40℃ to 200℃, has strong anti-vibration fatigue ability, and effectively avoids damage caused by chassis sinking.
For more challenging application scenarios, the Super Tech 316 stainless steel liquid cooling tube demonstrates even more extreme protective capabilities. Due to the addition of 2-3% molybdenum elements in it, the corrosion resistance against pitting and crevice corrosion of the 316 material has significantly improved. It is particularly suitable for coastal environments, high salt spray conditions, and fuel cell thermal management systems. Its working temperature range can even reach -196℃ to 800℃, and its service life can last up to 15-20 years, truly achieving zero leakage risk throughout the entire life cycle.
We are well aware that a stable supply chain is essential for the continuous growth of customer businesses. Therefore, China Super Tech has established a vast modern warehousing center to ensure adequate inventory. Whether you need standard specifications ranging from Φ6mm to Φ114mm, or special requirements with a wall thickness of 0.5mm to 3.0mm, our standard products can be delivered quickly, significantly shortening your procurement cycle.
At the same time, we not only offer standard pipes, but also provide deep customization services. From fixed-length cutting, precise pipe bending, to expansion and contraction processing, as well as end welding joints and flange matching, our one-stop service system can meet all the requirements of complex battery pack space layouts. Each liquid-cooled pipe produced is in compliance with ASTM A269/A312 and ISO 11439 standards for stainless steel pipes used in road vehicles, and detailed material reports are provided with the goods to ensure full traceability of key dimensions and air tightness throughout the process.
