Abstract

The invention discloses a battery pack and a heat radiation structure of the battery pack. The heat radiation structure is used for regulating the temperature of a plurality of battery units in the battery pack, and comprises a semiconductor heat exchange device and a heat radiation assembly, wherein the semiconductor heat exchange device is provided with a first side and a second side, the heat exchange between the first side and the internal part of the battery pack can be carried out through heat absorption or heat release, and the heat exchange between the second side and the external part of the battery pack can be carried out through heat absorption or heat release; and one part of the heat radiation assembly is in thermal contact with the battery units, and the other part of the heat radiation assembly is in thermal contact with the first side to transfer the heat between the semiconductor heat exchange device and the battery units. Compared with the cross-ventilation mode heat transfer, the heat radiation assembly can rapidly and efficiently transfer the heat between the battery units and the semiconductor heat exchange device, thereby enhancing the efficiency of the heat exchange between the battery pack and the external environment, and further enhancing the performance of the battery pack.

Description

technical field [0001] The invention relates to the technical field of batteries, in particular to a battery pack and its heat dissipation structure. Background technique [0002] The battery pack is formed by combining several battery cells in series or in parallel. The battery cells will generate a lot of heat during charging and discharging. If the heat cannot be effectively dissipated, the temperature of the battery pack will rise rapidly and the electrical characteristics of the battery will change. affect the performance of the battery pack. [0003] The current battery pack mainly dissipates heat in an air-cooled manner by setting a fan, but the efficiency of this heat dissipation method is low. Chinese patent CN2884544 proposes a semiconductor air conditioner to dissipate heat for the battery pack. The semiconductor air conditioner includes a semiconductor cooling sheet with a first side and a second side and two fans located on both sides of the semiconductor cooli...
