Abstract

The invention provides a thermal management device and a power source device, and relates to the technical field of battery thermal management. The thermal management device specifically comprises a liquid cooling plate and at least one heat conduction fin, wherein a liquid storage tank is arranged inside the liquid cooling plate, a liquid inlet and a liquid outlet are formed in the outside wall of the liquid cooling plate, the liquid inlet and the liquid outlet are communicated with the liquid storage tank, the liquid cooling plate is arranged on one side of a battery module, one end of each heat conduction fin is connected with the liquid cooling plate, and the other end of each heat conduction fin extends into the battery module and is placed in a gap between adjacent single batteries. Compared with the traditional heating and radiating device, the thermal management device greatly reduces thermal resistance between the liquid cooling plate and the battery module, and thermal conductivity is significantly increased.

Description

technical field [0001] The present invention relates to the technical field of battery thermal management, in particular, to a thermal management device and a power supply device. Background technique [0002] In recent years, due to the increasingly prominent problems of energy costs and environmental pollution, pure electric vehicles and hybrid vehicles have attracted the attention of the government and various automobile companies because of their advantages of greatly eliminating or even zero-emission vehicle exhaust. However, pure electric and hybrid vehicles still have many technical problems to be overcome, and battery service life and capacity fading are one of the important problems. [0003] The service life and capacity fading of the battery are closely related to the temperature difference and temperature rise of the battery system. The power battery will generate a lot of heat when it is working. If the heat cannot be discharged in time, the temperature inside ...
