Abstract

The invention relates to a battery cooling device, which comprises a battery base, a top cover, a temperature detection device and a heat dissipation fan bracket, and is characterized in that a plurality of grooves are formed in the battery base, the grooves are used for placing batteries, cooling pipelines are arranged in the grooves, vent holes are formed in the bottom surfaces of the grooves, and supports for bearing the batteries are arranged in the grooves; the support guarantees that a gap is reserved between the battery and the bottom face of the groove, the detection device is arrangedon the inner wall of the groove, and the lower portion of the base is connected with the heat dissipation fan bracket; a heat dissipation fan is arranged on the heat dissipation fan bracket. According to the device, the internal temperature is detected through the temperature detection device, so that the rotation of the heat dissipation fan and the flowing of a cooling liquid in the cooling pipeline in the groove are controlled, the cooling of the battery is realized, and the device is simple in structure and easy to realize.

Description

technical field [0001] The present disclosure relates to the technical field of battery cooling, in particular to a battery cooling device for a power battery pack of an electric vehicle. Background technique [0002] Electric vehicles use batteries to provide the energy they need to run. In order to ensure that the electric vehicle can travel long distances to meet the needs of users, it is usually necessary to install multiple battery packs to ensure the electric energy supply of the electric vehicle during long distance travel. However, during the long-distance driving of the electric vehicle, the temperature of the battery rises sharply. Moreover, the more batteries are carried, the overheating of the battery pack is particularly serious. If the battery works at a high temperature, its working life will be greatly reduced, and it will also affect the reliability and working performance of the electric vehicle. If the heat inside the battery system is not effectively co...
