A heat dissipation component of a new energy vehicle battery module

Abstract

A heat dissipation assembly for battery module of new energy vehicle disclosed in the invention includes an outer rack, a water-cooling pipe cooling area is fixedly connected between the outer frames,a water-cooled radiate tube is arrange inside the cool area of the water-cooled tube, a heat dissipation fin is fixedly connected at the top of the cooling area of the water cooling pipe, at the topof the heat dissipation fin, a fan heat dissipation frame is fixedly connected, a heat dissipation fan is fixedly connected inside the heat dissipation frame of the fan, Between the heat dissipation frame of the fan and the heat dissipation fin, a heat conduction patch is arranged, a dust-proof net is arrange on the top of the heat dissipation frame of the fan, an outer fixture is fixedly connected with the bottom of the outer frame, and a wat inlet fixing seat is fixedly connected with the outside of the outer fixture. The invention relates to the technical field of new energy vehicles. The new energy vehicle battery module heat dissipation module solves the problems of low air cooling heat exchange efficiency, poor heat dissipation effect, ineffective reduction of temperature and temperature difference, poor homogeneity of temperature, leakage of liquid and imperfect design of some water-cooled heat dissipation devices.

Description

technical field [0001] The invention relates to the technical field of new energy vehicles, in particular to a heat dissipation assembly for a battery module of a new energy vehicle. Background technique [0002] With the rapid development of new energy vehicles, the requirements for the performance and safety of new energy vehicles are also getting higher and higher. As one of the important components of new energy vehicles, the battery module is required to be able to charge and discharge at a high rate in order to increase the power of the vehicle and shorten the charging time. The battery cells will generate a lot of heat during the high-rate charge and discharge process. In addition, the battery module has a compact structure and the heat is easy to accumulate, resulting in local overheating or uneven temperature of the battery module, which will lead to performance degradation and capacity attenuation of the battery module. Thermal runaway endangers the personal and p...
