When in use, the downward pressing cross bar 401 is mounted on the upper end of the battery A, and the side rod 402 is inserted into the fixed block 406. Under the action of the return spring 404, the L-shaped rod 405 is inserted into the positioning pin hole 403, thereby completing the locking of the position of the side rod 402;

This wrapping method makes the heat dissipation more uniform.

[0040] The refrigerant exchanges heat with the air inside the heat-conducting base box 100 through the outer wall of the refrigerant conduit 200, thereby cooling the air entering the heat-conducting base box 100, which helps to reduce the heat dissipation temperature. The cooling here is active cooling;
