One end of the first heat sink fins 14 extends out of the box body 1. The other end of the sheet 14 extends into the inside of the serpentine tube 13 on the lower side.

The box body 1 is installed on the front side of the vehicle. When the vehicle is driving forward, the two wind-driven mechanisms are driven to work, thereby stirring the coolant in the liquid storage chamber 12 on the right side to the serpentine tube 13 on the upper side. The inside is circulated, and the cooling liquid flows into the left liquid storage chamber 12 through the upper serpentine tube 13, and the wind drive mechanism in the left liquid storage chamber 12 stirs and drives the cooling liquid again, and flows into the lower snake. The cooling liquid in the two liquid storage chambers 12 and the two serpentine tubes 13 will be automatically driven in the process of moving the vehicle forward. During the flow transition, the two serpentine tubes 13 are used to dissipate heat to the battery in the placement cavity 11, and the spiralling manner of the serpentine tubes 13 can increase the heat dissipation area and improve the heat dissipation effect;
