Abstract

An automobile battery liquid cooling heat dissipation device based on a steam cavity heat dissipation technology comprises a heat conduction steam cavity, a liquid cooling channel and a plurality of power batteries, the liquid cooling channel is of a return bending structure, the heat conduction steam cavity tightly attached to the liquid cooling channel is arranged between bending areas of the liquid cooling channel, a plurality of battery mounting grooves are formed in the heat conduction steam cavity, and a power battery is fixed in each battery mounting groove. According to the design, the steam cavity structure is adopted for heat transfer, the steam cavity structure is good in heat dissipation performance, flexible, simple and convenient, local heat generated by the battery pack module can be rapidly taken away, high effective heat dissipation of an electric vehicle battery under the high heat flux density is achieved, meanwhile, uniform temperature distribution is kept in the running process, and the service life and the cruising ability of the automobile battery are prolonged.

Description

technical field [0001] The invention relates to a liquid-cooled heat dissipation device for an automobile battery based on the heat dissipation technology of a steam cavity, and is particularly suitable for improving the heat dissipation efficiency of an automobile power battery pack. Background technique [0002] In recent years, with the rapid development of industry, the automobile industry has consumed a huge amount of fossil energy, and has also brought serious environmental pollution problems. By improving the oil supply system and exhaust gas purification technology, the effect of controlling energy consumption and environmental pollution is not significant. New energy vehicles, especially pure electric vehicles, are favored by governments and automobile companies of various countries because of their advantages of energy saving and almost zero emission of vehicle exhaust. In order to promote my country's energy conservation and ecological civilization construction, ...
