[0002] In recent years, with the rapid development of electric passenger vehicles, high-performance and large-capacity batteries are needed to provide power for these devices. Currently, lithium batteries are more commonly used. However, as the current increases, lithium batteries heat up unevenly and more obviously. The pole is the hottest, and the sides and bottom have the largest heat dissipation area. The positive and negative electrodes also produce temperature differences due to different electrochemistry and materials.

[0003] Lithium batteries are sensitive to temperature. If they are operated at a temperature higher than room temperature for a long time, their lifespan will decrease with every 10 degrees increase in temperature. If the temperature exceeds a certain "high temperature", thermal aging will also occur. At present, the demand for fast charging and high-power discharge in automobiles is increasing, especially fast charging, which is very popular, thus increasing the difficulty of thermal management.

[0004] The current automotive battery thermal management equipment needs to be cooled during use in order to improve its thermal management effect on the power battery. However, the current air-cooled thermal management equipment cooling device cannot perform all-round air cooling on the thermal management equipment during use, which is prone to produce dust. At the same time, as the cooling time increases, the heat dissipation holes on the cooling equipment are prone to dust accumulation, which will affect the later cooling effect over time. Therefore, further improvement is needed. Summary of the invention
