[0002] Today, new energy vehicles have entered thousands of households and are gaining increasing public recognition. Currently, battery packs are typically cooled by natural cooling and liquid cooling. Natural cooling often fails to dissipate excess heat in the battery pack, affecting the normal operation of the power battery and significantly limiting its use in fully sealed battery packs. Liquid cooling often involves adding a liquid cooling plate to the battery pack. Heat is transferred between the liquid cooling plate and a specific part of the battery via a thermal pad or thermal adhesive. For example, liquid cooling plates are installed on the bottom and sides of a square battery for heat conduction, and the cylindrical surface of a cylindrical battery cell is connected to the liquid cooling plate for heat conduction.
