Battery cooling device special for new energy automobile

Abstract

The invention discloses a battery cooling device special for a new energy automobile. The battery cooling device comprises a sleeve body and an upper cover, wherein the bottom of one side of the uppercover is connected with the sleeve body via a rotation shaft, the sleeve body comprises a base and hollow insulation plates, the hollow insulation plates are perpendicularly arranged at two sides ofa part above the base, the hollow insulation plates are filled with cooling liquids, a cooling assembly is fixedly arranged on an outer wall of each hollow insulation plate, a cooling plate is fixedlyarranged on an inner wall of the base, a cooling fan group is arranged in an inner cavity of the base, and an air outlet is formed in the bottom of the base. The battery cooling device is simple in principle, effective cooling of an automobile battery can be achieved, the cooling effect is good, and the service lifetime of the automobile battery can be prolonged.

Description

technical field [0001] The invention relates to the technical field of battery cooling, in particular to a special battery cooling device for new energy vehicles. Background technique [0002] New energy vehicles refer to all other energy vehicles except gasoline and diesel engines, including fuel cell vehicles, hybrid vehicles, hydrogen energy vehicles and solar vehicles. Its exhaust emissions are relatively low. According to incomplete statistics, there are more than 4 million liquefied petroleum gas vehicles and more than 1 million natural gas vehicles in the world. At present, most of the new energy vehicles on sale in the Chinese market are hybrid vehicles and pure electric vehicles. According to the definition announced by the National Development and Reform Commission of the People's Republic of China, new energy vehicles refer to the use of unconventional vehicle fuels as power sources (or the use of conventional vehicle fuels and new vehicle power devices), and th...

Problems solved by technology

cause a lot of heat

If the heat is not dissipated and suppressed well during the running of the vehicle, there will be a large temperature difference between the individual batteries, resulting in uneven distribution of the heat generation temperature field of the battery pack, which may eventually cause the electrochemical The performance is seriously reduced; at the same time, the temperature difference of each single battery will also cause the difference in the charge and discharge capacity of each power battery, which will eventually reduce the cycle life of the battery pack and greatly reduce the amount of repeated charging. In addition, if the temperature is too high, it is easy to burn out the battery or Vehicle electrical equipment
