AI Technical Summary
Technical Problem
In existing battery modules, the temperature control of the cells relies on liquid cooling plates, which have low heat exchange efficiency and cannot achieve efficient heat dissipation and high-precision temperature control.
Method used
A spiral tube is used to connect the internal and external cooling channels of the liquid cooling plate and the cover plate. Branch channels and expansion channels are designed to increase the heat transfer area, and modular design is used to improve assembly efficiency.
Benefits of technology
This achieves full coverage of the cell surface with coolant, improving heat dissipation efficiency and temperature control accuracy, preventing heat accumulation, and simplifying the production and maintenance process.
