Battery Cooling Devices for Electric Vehicles

Abstract

The invention discloses a battery cooling device for an electromobile. The battery cooling device structurally comprises an electromobile shell, an electric generator, an inverter, a battery and a battery cooling device, wherein the battery is fixedly installed on one side, near to the tail end of the electromobile, of the bottom of an inner cavity of the electromobile shell, the battery cooling device wraps the battery, the battery cooling device is fixedly connected with the battery, both the electric generator and the inverter are installed on a panel at the bottom of the inner cavity of the electromobile shell, and the electric generator is electrically connected with the battery through the inverter. Under the combined actions of a first cooling mechanism, a refrigerating plant, an accelerated cooling mechanism, a mechanical drive accelerating mechanism, a differential pressure drive mechanism, a drive control device and a circulating cooling switch control device, the heat produced in the working of the battery is dissipated in time, the drop of water on the outer wall of a circulating pipe is blown dry while an air wheel cools, or the drop of water directly falls in a trapezoidal refrigerating cavity, so that the potential safety hazard is eliminated.

Description

technical field [0001] The invention relates to the field of heat dissipation structures inside automobiles, in particular to a battery heat dissipation device for electric automobiles. Background technique [0002] At present, the battery of electric vehicles is generally installed on the chassis between the four wheels or in the trunk. Due to the long working time of the battery and the need for repeated charging, it is very easy to generate heat; thus, the heat dissipation of the battery becomes particularly important. [0003] An electric vehicle (BEV) refers to a vehicle that is powered by a vehicle-mounted power supply, drives the wheels with a motor, and meets the requirements of road traffic and safety regulations. Due to its smaller impact on the environment than traditional cars, its prospects are widely optimistic, but the current technology is still immature. [0004] The battery casing in the existing electric vehicles is made of ordinary materials, which has p...

Problems solved by technology

Due to its smaller impact on the environment than traditional cars, its prospects are widely optimistic, but the current technology is not yet mature

[0004] The battery casing in the existing electric vehicles is made of ordinary materials, which has poor ventilation and heat dissipation, and unreasonable structural design, which cannot quickly discharge the heat emitted by the battery, resulting in local high temperature and affecting the service life of the battery. Therefore, we propose an electric Car battery cooling device to solve the above problems

[0005] In the prior art, electric vehicles use a refrigerator to dissipate heat for the battery. After the refrigerator works, it is very easy to form water dew on the surface of the battery and the inner and outer walls of the box, which brings a great potential safety hazard.
