Temperature control assembly and battery module

Abstract

The embodiment of the invention provides a temperature control assembly and a battery module. The battery module comprises a multilayer sub module, wherein the temperature control assembly comprises aliquid cooling pipe and a bending profile element; the liquid cooling pipe comprises a plurality of sub flat pipes and at least one bending connecting part; the plurality of sub flat pipes are arranged in a mutually separated way; in addition, an accommodating space for accommodating at least one layer of sub module is formed between the two adjacent sub flat pipes; the adjacent sub flat pipes are communicated through one bending connecting part; the bending profile element is sleeved on the bending connecting part of the liquid cooling pipe so that the bending connecting part maintains the bending state under the effect of the correspondingly sleeved bending profile element. The fracture probability of the temperature control assembly is low; the corresponding bending part cannot easilydeform; the battery module can be subjected to temperature control management under the condition of lowering the fracture probability; the heat management cost of the battery module is reduced.

Description

technical field [0001] The invention relates to the technical field of battery heat management, in particular to a temperature control component and a battery module. Background technique [0002] With the promotion and development of new energy technologies, the use of pure electric or hybrid vehicles is becoming more and more popular, and the use of new energy battery systems is becoming more and more extensive. For the battery system, the energy comes from the battery module, and the battery module will generate a lot of heat during charging and discharging. management device. [0003] At present, the mainstream in the industry generally adopts the method of installing a liquid cooling tube in the battery module and injecting liquid with a preset temperature into the liquid cooling tube to control and manage the temperature of the single cells in the battery module. The battery module usually includes multi-layer sub-modules arranged in layers. Each sub-module includes ...
