Problems solved by technology

One is to use water cooling to dissipate heat, which needs to provide electric energy for the circulating pump to work, which will consume the internal energy of the battery
The second is to use the high latent heat performance of the phase change material to transfer the heat of the power battery to the phase change material. When the battery is squeezed or the phase change material expands at high temperature, there will be contact between the phase change material and the power battery electrode, resulting in a short circuit of the battery

Abstract

The invention provides a multi-cooling mode power battery heat dissipation device, comprising a heat dissipation box, a cover for sealing the heat dissipation box, several battery storage tanks arranged in the heat dissipation box, an air cooling module, and a heat pipe cooling module. Compared with the prior art, the present invention has a simple and reasonable structure, and micro-manufactures the surface of the air-cooled flow channel, so that the air-cooled gas changes from a laminar flow state to a turbulent flow state, so that it absorbs the heat of the battery, and then transfers the heat of the battery to the battery exterior. The copper plate is used to increase the contact area between the heat pipe, the battery tab and the bottom of the battery, improve the heat transfer efficiency of the heat dissipation system, make the temperature distribution of the battery more uniform, and reduce the number of heat pipes and reduce the cost.

Description

technical field [0001] The invention relates to the field of heat dissipation of power batteries of electric vehicles and hybrid vehicles, in particular to a power battery heat dissipation device with multiple cooling modes. Background technique [0002] Nowadays, electric vehicles and hybrid vehicles have received great attention from the society, but there are still obstacles such as battery explosions that hinder the development of electric vehicles. Among them, the safety of power batteries has caused society to change the view of electric vehicles. If the power battery explodes due to high operating temperature, it is necessary to design a complete power battery cooling system to keep the working temperature of the battery pack within a certain range and improve the heat dissipation performance of the power battery. The present invention proposes a power battery heat dissipation system based on air cooling, fan and heat pipe multi-cooling methods. The surface micro-manu...
