Abstract

The invention provides a heat management device and a battery module. The battery module comprises multiple layers of sub-modules. The heat management device comprises a liquid cooled flat tube arranged in the battery module, and the liquid cooled flat tube is in contact with each layer of sub-modules. The liquid cooled flat tube comprises a plurality of sub-flat tubes arranged at intervals and aplurality of bending and connecting parts, a space for accommodating the one layer of sub-modules or the two layers of sub-modules is formed between the every two adjacent sub-flat tubes, and the every two adjacent sub-flat tubes are communicated through the one bending and connecting part. Therefore, the liquid cooled flat tube can be made into a uniform shape, the sub-flat tubes of correspondinglengths are intercepted according to the lengths of all the sub-modules and are arranged at intervals, and the adjacent sub-flat tubes are connected through the one bending and connecting part.

Description

technical field [0001] The present application relates to the technical field of battery thermal management, in particular, to a thermal management device and a battery module. Background technique [0002] As the main energy storage component of electric vehicles, battery modules are key components of electric vehicles and directly affect the performance of electric vehicles. The cells in the battery module may need to be heated or dissipated during use, so as to prevent the cells from being in a low or high temperature state for a long time, which will affect the performance of the cells and reduce the service life of the cells. [0003] At present, a liquid-cooled flat tube is usually installed in the battery module, and liquid at a preset temperature is injected into the liquid-cooled flat tube to heat or dissipate heat for the battery cell. The battery module usually includes multi-layer sub-modules arranged in layers, and the liquid-cooled flat tubes are usually wound...
