Heat dissipation device and battery module

Abstract

The embodiment of the invention relates to the field of batteries, and particularly relates to a heat dissipation device and a battery module. The heat dissipation device comprises a body, an isolation structure, a liquid inlet and a liquid outlet, wherein the body and the isolation structure are of hollow structures; the isolation structure is arranged in the body and can form a plurality of accommodating structures together with the body; batteries are arranged in the plurality of accommodating structures; the liquid inlet is formed in the body and the liquid outlet is formed in a position, away from the liquid inlet, of the body, wherein the liquid inlet, the liquid outlet, the isolation structure and the body are communicated with each other. The embodiment of the invention also provides the battery module including the plurality of batteries, cooling liquid and the dissipation device, wherein the cooling liquid is filled with the body and the isolation structure, and the plurality of batteries can be completely and reliably cooled by the cooling liquid, so that the heat dissipation performance of the heat dissipation device is improved.

Description

technical field [0001] Embodiments of the present invention relate to the field of batteries, in particular, to a heat dissipation device and a battery module. Background technique [0002] In the battery system, in order to form a larger energy system, it is necessary to combine individual batteries with smaller energy in series or in parallel to form battery modules of different sizes. During the working process of the battery module, the battery will generate heat. If the temperature is too high, it may affect the normal operation of the battery module or even damage the battery module. In the prior art, the temperature of the battery module is mostly lowered by contacting the liquid-cooled flat tube with the battery for cooling, but there may be poor contact, resulting in incomplete cooling of the battery. Contents of the invention [0003] In view of this, the present invention provides a heat dissipation device and a battery module to solve the above problems. [0...
