A lithium battery cooling system for electric vehicles

Abstract

The invention discloses a lithium battery heat dissipation system for electric vehicles, which includes a bracket, an annular heat dissipation fin structure is arranged in the support, a lithium battery is arranged in the annular heat dissipation fin structure, the outer wall of the lithium battery and the A heat conduction structure is arranged between the inner walls of the annular fin structure, and the valve body is provided with an air inlet pipe, an air outlet pipe and a piston pipe, and the air inlet pipe, the air outlet pipe and the piston pipe are respectively communicated with the valve chamber, and the A one-way air valve is arranged in the air inlet pipe and the air outlet pipe; the air outlet pipe includes a thick pipe communicating with the valve cavity and a thin pipe connected with the thick pipe; the structure of the present invention can quickly dissipate heat from the lithium battery , by setting multiple airflow control structures to work in turn to ensure that the heat dissipation fins can achieve the maximum heat exchange effect, so that the heat exchange can be accelerated, and after the air is compressed, the temperature will drop rapidly, ensuring the heat dissipation effect of the lithium battery and preventing the high temperature of the lithium battery Work.

Description

technical field [0001] The invention relates to a battery heat dissipation system used in lithium batteries of electric vehicles, in particular to a lithium battery heat dissipation system used in electric vehicles. Background technique [0002] Battery packs and lithium batteries are used in power supply systems in various fields. With the rise of electric vehicles, more and more people choose electric vehicles for travel, and their environmental protection is particularly outstanding. The battery of electric vehicles has become an important measure of vehicle performance. One of the indicators, due to the dense arrangement of car battery packs, and the large input and output power, and the batteries are often buried inside the car, the battery body heats up more seriously. If the battery works at high temperature for a long time, it will not only affect the life of the battery itself, but also It will also affect the performance of the entire electric vehicle. Not only tha...

[0002] Battery packs and lithium batteries are used in power supply systems in various fields. With the rise of electric vehicles, more and more people choose electric vehicles for travel, and their environmental protection is particularly outstanding. The battery of electric vehicles has become an important measure of vehicle performance. One of the indicators, due to the dense arrangement of car battery packs, and the large input and output power, and the batteries are often buried inside the car, the battery body heats up more seriously. If the battery works at high temperature for a long time, it will not only affect the life of the battery itself, but also It will also affect the performance of the entire electric vehicle. Not only that, but if the temperature is too high, it will cause the electric vehicle to ignite spontaneously, which will cause damage and property loss, and seriously threaten personal life. cooling system
