Air circulation box for battery components

Abstract

The invention discloses an air circulation box for a battery assembly, which comprises a box, a vertically movable shock-absorbing hanger is arranged on the upper part of the box, and a plurality of heat-dissipating racks arranged in parallel are arranged on the top of the shock-absorbing hanger. The heat sink is connected to the shock-absorbing hanger in rotation. A horizontal chute is provided on the inner wall of the box, and sliding blocks are provided at both ends of the chute. Both ends of each slider are provided with The shock absorbing spring arranged along the direction of the chute, the shock absorbing hanger is provided with a support frame that can push the slider to move along the chute, and the top of the shock absorbing hanger is provided with a driven frame that is rotatably connected with the heat sink , the box is provided with a shift fork that drives the driven frame to move horizontally when the driven frame moves vertically. straight guide column, and the inner bottom of the box body is provided with a guide sleeve slidingly fitted with the guide column. The present invention aims to provide a battery assembly air circulation box which reduces vibration and improves heat dissipation.

Description

technical field [0001] The invention belongs to the field of battery heat dissipation, and in particular relates to an air circulation box of a battery assembly. Background technique [0002] In the current battery manufacturing process, in order to meet the use environment, it is often necessary to use a plurality of battery slices or battery cells to be connected in series and parallel to achieve appropriate power and power design requirements. When the battery is in the outdoor environment and in the process of moving, such as the battery of the car, the uneven road causes the battery to bump at the same time, which increases the probability of battery damage and shortens the service life of the power supply. During the normal use and discharge process of the battery, even when it is not in use, such as storage and transportation, the battery will slowly discharge and generate a certain amount of heat due to the existence of internal resistance. When the battery is disch...

AI Technical Summary

Problems solved by technology

When the battery is being discharged, the heat generated is dissipated outward through the outer casing of the battery, and when the current of the circuit increases and the power consumption increases, the heat generated by the battery rises sharply, which easily exceeds the heat dissipation performance of the outer casing, resulting in overheating of the battery and the safety of the battery. The performance is reduced, and the service life is greatly shortened
