A battery pack with dual active cooling methods

Abstract

The invention discloses a battery pack with dual active cooling modes, which includes a battery pack body. In the present invention, the heat generated by the battery pack body is in contact with the heat conduction rod during the rising process, and the heat conduction rod transfers the heat to the heat dissipation pipe through the heat conduction medium. Under the action of the temperature sensor 1 and the controller, the heat dissipation fan 2 rotates. The heat of the heat dissipation pipe can be discharged outward, realizing the heat dissipation of the battery pack body. This heat dissipation method can prevent dust from entering the inside of the connection cover. Under the action of the temperature sensor 2 and the controller, the heat dissipation fan 1 and the servo motor Running, under the action of the driving gear, gear plate and connecting rod, the baffle no longer covers the dust-proof net, and under the action of the heat dissipation fan 1, it can quickly dissipate heat from the inside of the connection cover. This device realizes heat dissipation At the same time, it also plays a dust-proof role, which can reduce the contact between dust and the battery pack body, and can effectively prolong the service life of the battery pack body.

Description

technical field [0001] The invention relates to the technical field of battery packs, in particular to a battery pack with dual active heat dissipation methods. Background technique [0002] A general battery pack includes several single cells, which are fixed by welding connections; in order to facilitate the assembly and connection between the single cells of the battery pack, a connection unit with slots at both ends of the axial direction is now proposed. The slots at both ends are respectively used for inserting the positive and negative poles of the single battery, and the connecting unit can also be provided with conductive sheets for parallel connection between radially adjacent batteries or series connection between axially adjacent batteries. Adjacent connection units can also be plugged in through the slots between their adjacent surfaces. [0003] The battery pack will generate a lot of heat during use. In order to facilitate the heat dissipation of the battery ...

AI Technical Summary

Problems solved by technology

[0003] The battery pack will generate a lot of heat during use. In order to facilitate the heat dissipation of the battery pack, there are usually cooling holes on the side wall of the box where the battery pack is placed. However, there are still many problems in the use of this heat dissipation method. Disadvantages, for example, external dust easily enters the interior of the box through the heat dissipation holes and adheres to the battery pack. With the accumulation of dust, the heat dissipation effect of the battery pack is affected, and the service life of the battery pack is easily reduced.
