Abstract

The invention provides a cooling plate of a storage battery. The cooling plate comprises a cooling plate upper cover plate and a cooling plate lower shell, wherein a heat conduction end face of the cooling plate upper cover plate is attached to the storage battery, and the cooling plate lower shell is fixedly installed at the back side of the cooling plate upper cover plate; the cooling plate lower shell and the cooling plate upper cover plate define a circulation channel of cooling liquid; and the cooling plate upper cover plate is made of a metal material, and the cooling plate lower shell is prepared from a thermoplastic polymer material. The cooling plate upper cover plate is attached to the storage battery to transmit heat generated by the storage battery, and the cooling plate uppercover plate and the cooling plate lower shell jointly define the circulation channel of the cooling liquid; the cooling plate is composed of the cooling plate upper cover plate made of the metal material and the cooling plate lower shell made of the thermoplastic polymer material; and by use of the characteristic that the heat conduction coefficient of the polymer material is lower than that of the metal material, a certain thermal insulation function can be achieved, the thermal efficiency of a cooling system is improved, the weight of the cooling plate is lowered, and material cost is lowered. The invention furthermore provides an electric automobile.

Description

technical field [0001] The invention relates to the technical field of electric vehicles, and more specifically, relates to a cooling plate of a storage battery and the electric vehicle. Background technique [0002] Due to its environmental friendliness, electric vehicles have been paid more and more attention by people, and their development has also shown a vigorous trend. As the power source of electric vehicles, the traction battery system plays an important role in the design and development of electric vehicles. This invention describes a new type of cold plate used for cooling the traction battery system, which can improve the cooling efficiency, improve the performance of the traction battery system and Effectively reduce the weight and cost of the battery system. [0003] The lightweight of automobiles is an important part of my country's energy strategy. Reducing the weight of the vehicle is of great benefit to the overall economical use of the automobile, flexib...
