|1. (WO2018133278) ELECTRIC CAR, AND LIQUID DELIVERY DEVICE AND HEAT DISSIPATION METHOD SUITABLE FOR ELECTRIC CAR|
|Applicants:||GRADUATE SCHOOL AT SHENZHEN, TSINGHUA UNIVERSITY
|Title:||ELECTRIC CAR, AND LIQUID DELIVERY DEVICE AND HEAT DISSIPATION METHOD SUITABLE FOR ELECTRIC CAR|
Provided in the present invention is an electric car, comprising a battery pack and a heat dissipation device used for dissipating heat of the battery pack. The heat dissipation device comprises a heat dissipation member and a heat dissipation pipe embedded in the heat dissipation member. The heat dissipation member is made from a phase transition material. The heat dissipation member is in contact with the battery pack to create heat transfer. The heat dissipation member transfers the heat of the battery pack to the heat dissipation pipe. The heat dissipation pipe is configured to be filled with a cooling liquid. Two ends of the heat dissipation pipe extend from the heat dissipation member to a car body of the electric car. A cooling liquid inlet and cooling liquid outlet are formed on the car body of the electric car, the cooling liquid inlet is used to provide an inlet for the cooling liquid to enter the heat dissipation pipe, and the cooling liquid outlet is used to provide an outlet for the cooling liquid to exit the heat dissipation pipe. Also provided in the present invention are a liquid delivery device and heat dissipation method for an electric car, providing low energy consumption, enabling a low cost, and facilitating easy and convenient heat dissipation for a battery pack.
