Novel lithium battery heat dissipation system applied to electric automobile

Abstract

The invention discloses a novel lithium battery heat dissipation system applied to an electric automobile. The system comprises a bracket, an annular heat dissipation fin structure is arranged in the bracket, a lithium battery is arranged in the annular heat dissipation fin structure, and a heat conduction structure is arranged between the outer wall of the lithium battery and the inner wall of the annular heat dissipation fin structure. An air inlet pipe, an air outlet pipe and a piston pipe are arranged on the valve body; the air inlet pipe, the air outlet pipe and the piston pipe are respectively communicated with the valve cavity, and one-way air valves are arranged in the air inlet pipe and the air outlet pipe; and the air outlet pipe comprises a thick pipe communicated with the valve cavity and a thin pipe connected with the thick pipe. By means of the structure, the lithium battery can be rapidly cooled; the multiple airflow control structures are arranged to work in turn, so that it is guaranteed that the cooling fins can achieve the maximum heat exchange effect; and after heat exchange is accelerated and air is compressed, the temperature is rapidly reduced, the cooling effect of the lithium battery is guaranteed, and high-temperature work of the lithium battery is prevented.

Description

technical field [0001] The invention relates to a battery heat dissipation system used in lithium batteries of electric vehicles, in particular to a novel heat dissipation system of lithium batteries 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. N...

[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
