Embodiment Construction

[0043] As the most basic and important component of the electric vehicle power battery system, the battery's performance affects the safe and reliable operation of the electric vehicle. The battery will generate heat during operation. When the battery generates a large amount of heat, it is prone to risks such as thermal runaway. Therefore, the battery The cooling system is an important guarantee for the normal operation of the electric vehicle power battery system.

[0044] The inventor found through investigation that most of the existing technologies for cooling the battery have poor heat dissipation effects. Most of the existing technologies use liquid-cooled flat tubes or air-cooled devices to cool down the battery. The liquid-cooled flat tubes may have problems of leakage or poor fluidity of the regulating fluid. The design of the air-cooled device is relatively complicated, which increases the weight of the entire battery pack. Moreover, it is difficult for the liquid-c...
