Abstract

The invention relates to a power battery cooling structure and system. The power battery cooling structure comprises an aluminum plate and a sealing structural part, wherein a cooling cavity is formed at the edge of the aluminum plate; the cooling cavity is formed by bending the edge of the aluminum plate and sealing with the plane of the aluminum plate; when the aluminum plate is bent, a seam is sealed by utilizing the sealing structural part. The power battery cooling structure and system are suitable for controlling the utilization temperature of a battery cell through cooling liquid or a phase change material. The power battery cooling system comprises two or more than two power battery cooling structures based on a liquid cooling technology and two module parallel structural parts. According to the power battery cooling structure and system provided by the invention, the aluminum plate is bent to form a main structure and is matched with the sealing structural part to assemble and mold; the operation is simple, the cost is low and the cooling efficiency of the battery cell can be improved.

Description

technical field [0001] The invention relates to the technical field of power battery heat control, in particular to a power battery cooling structure and system. Background technique [0002] With the rapid development of the new energy vehicle market, the demand for power batteries increases accordingly. In addition, as the energy density increases, the calorific value of the battery increases accordingly. Natural cooling and air cooling can no longer meet the heat dissipation requirements. In the event of an accident, once the heat cannot be exported in time, it is easy to cause thermal runaway of the battery. Since the liquid has a high specific heat capacity, it can take away a large amount of heat per unit time. The liquid cooling solution can better meet the heat dissipation requirements of the battery module. At present, there are two types of battery liquid cooling systems, one is to fix cooling devices such as cold plates on the outside of the battery module to con...
