AI Technical Summary
The heat dissipation structure of the existing battery pack is difficult to meet the heat dissipation needs of the battery pack when the temperature is high.
A heat dissipation device for a vehicle battery pack is designed, including a heat dissipation box and a liquid storage device. The heat sink box forms a liquid storage chamber for introducing coolant to dissipate heat to the battery pack; the liquid storage device is used to store coolant and introduces the coolant into the liquid storage chamber when the temperature of the battery pack is higher than the preset temperature.
By introducing coolant, the temperature of the battery pack can be effectively reduced, the heat dissipation needs of the battery pack, and the working state of the battery pack can be improved.
