Heat dissipation device of lithium battery module

Abstract

The heat dissipation device comprises a bottom plate and a protection cover fixedly arranged at the top of the bottom plate, a battery body is installed at the position, located at the top of the bottom plate, in an inner cavity of the protection cover, an air inlet and an air outlet are formed in the two sides of the protection cover correspondingly, and a filter screen is arranged at the air outlet; a filtering mechanism is arranged at the air inlet; the filtering mechanism comprises a filtering belt arranged at the air outlet, filtering holes are formed in the filtering belt, and the top end of the filtering belt is fixed to the top wall of the interior of the air inlet; when the free end of the filter belt moves upwards, the limiting block can be synchronously driven to move upwards, and the limiting block moves relative to the surface of the filter belt in the upward moving process, so that the filter belt is always in a bent state at the lowest point of the filter belt, the filter holes in the filter belt are extruded, and the filter holes are promoted to deform; and dust adhered to the filtering holes is crushed and extruded out, so that the filtering belt can be conveniently cleaned.

Description

technical field [0001] The invention relates to the technical field of heat dissipation of lithium batteries, in particular to a heat dissipation device of a lithium battery module. Background technique [0002] With the rapid development of battery technology, more and more batteries are used in life. Lithium batteries are more and more used due to their light weight and large energy storage. However, after a long time of operation, lithium batteries will generate a lot of heat. If the heat is not dissipated in time, it will easily lead to a stable increase in the interior of the lithium battery, which will affect the performance of the lithium battery. [0003] Chinese invention patent CN113555631A discloses an air-cooled and heat-dissipating battery, which includes a heat-insulating shell on which an upper cover is fixedly mounted. In the present invention, a side heat absorption port is arranged between each group of batteries, so that the generated heat enters the heat...

AI Technical Summary

Problems solved by technology

[0006] The purpose of the present invention is to provide a heat dissipation device for a lithium battery module to solve the problem that the filter components on the existing equipment only filter the dust in the air through the filter screen in the above-mentioned background technology. The environment and the dust in the air often make the dust stick to the filter holes of the filter. As time goes by, the dust gradually dries and hardens at the filter holes, making it difficult to clean and affecting the efficiency of the air intake.
