Battery pack with dual active heat dissipation modes

Abstract

The invention discloses a battery pack with dual active heat dissipation modes. The battery pack comprises a battery pack body. According to the battery pack, heat generated by the battery pack body is in contact with a heat conduction rod in the rising process, the heat conduction rod transmits the heat to a heat dissipation pipe through a heat conduction medium, a second heat dissipation fan rotates under the action of a first temperature sensor and a controller, the heat of the heat dissipation pipe can be discharged outwards, and heat dissipation of the battery pack body is achieved; because of the heat dissipation mode, dust is prevented from entering a connecting cover; under the action of a second temperature sensor and a controller, a first cooling fan and a servo motor operate, under the action of a driving gear, a fluted disc and a connecting rod, a baffle does not cover a dustproof net any more; under the action of the first cooling fan, the interior of the connecting covercan be rapidly cooled. According to the device, the dustproof effect is achieved while heat dissipation is achieved, contact between dust and the battery pack body can be reduced, and the service lifeof the battery pack body can be effectively prolonged.

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.
