Problems solved by technology

[0004] At present, the installation of the liquid cooling plate in the battery pack often has great limitations. With the continuous improvement of the energy density and volume density of the battery pack, the space left for the water cooling system is becoming more and more compact, which cannot provide enough space for According to the established method of installation, the existing battery pack water cooling plate is heavy and requires a relatively large installation space

Abstract

The invention discloses a novel uniform temperature liquid cold plate. The liquid cold plate comprises a heat-conducting fixing plate, a plurality of diversion pipes, and two collecting pipes. The twoends of each collecting pipe are closed. The two collecting pipes are correspondingly an inlet collecting pipe and an outlet collecting pipe. The plurality of diversion pipes and the collecting pipesare communicated. The plurality of diversion pipes are arranged on a plate surface of the heat-conducting fixing plate, and The other side of the heat-conducting fixing plate is in close contact witha battery module. According to the novel uniform temperature liquid cold plate, the diversion pipes are connected with the heat-conducting fixing plate, the heat of the battery module is transferredfrom an aluminum plate to the diversion pipes, the heat-conducting fixing plate can uniformly distribute heat to an entire panel, and the heat is taken away by the diversion pipes to achieve uniform heat dissipation and to reduce temperature difference of the battery module.

Description

technical field [0001] The invention belongs to the field of battery heat dissipation, and in particular relates to a novel uniform temperature liquid cold plate. Background technique [0002] With the shortage of traditional energy sources such as oil and natural gas, and the continuous enhancement of people's awareness of environmental protection, electric vehicles have emerged as the times require and have been continuously developed. [0003] The battery pack, the core component of an electric vehicle, will generate a lot of heat during charging and discharging. If the heat cannot be dissipated, it will seriously affect the life and performance of the battery. Therefore, for the stability of electric vehicles, it is necessary to A specific device is required to dissipate heat from the battery. [0004] At present, the installation of the liquid cooling plate in the battery pack often has great limitations. With the continuous improvement of the energy density and volume...
