Problems solved by technology

[0002] The flow direction of the liquid-cooling medium in the traditional liquid-cooling system is fixed. Therefore, as the liquid-cooling medium flows in the liquid-cooling component, the temperature of the liquid-cooling component upstream of the liquid-cooling medium will be different from that of the liquid-cooling medium. The temperature of the liquid-cooled component at the downstream is different, so the heat transfer effect of the liquid-cooled component on the battery module in the battery pack will also be different, resulting in uneven heat transfer from the liquid-cooled component to the battery module, making the battery module There is a large temperature difference between the phenomenon, there is room for improvement

Abstract

The invention discloses a liquid cooling system for a battery pack, the battery pack and a vehicle. The liquid cooling system for the battery pack comprises a liquid cooling assembly and a liquid cooling medium flow direction changing device. The liquid cooling medium flow direction changing device is connected between a liquid cooling source and the liquid cooling assembly, and the liquid cooling medium flow direction changing device can change the flow direction of a liquid cooling medium in the liquid cooling assembly. According to the liquid cooling system, the flow direction of the liquid cooling medium in the liquid cooling assembly can be changed by arranging the liquid cooling medium flow direction changing device, so that an effective uniform-temperature heat exchange effect is achieved, the problem that the temperature difference is large during heat exchange of the battery modules is avoided, the battery modules can operate in a relatively consistent temperature environment, therefore, the safety coefficient of the battery pack is improved, and the service life of the battery pack is prolonged.

Description

technical field [0001] The invention relates to the technical field of vehicles, in particular to a liquid cooling system for a battery pack, a battery pack and a vehicle. Background technique [0002] The flow direction of the liquid-cooling medium in the traditional liquid-cooling system is fixed. Therefore, as the liquid-cooling medium flows in the liquid-cooling component, the temperature of the liquid-cooling component upstream of the liquid-cooling medium will be different from that of the liquid-cooling medium. The temperature of the liquid-cooled component at the downstream is different, so the heat transfer effect of the liquid-cooled component on the battery module in the battery pack will also be different, resulting in uneven heat transfer from the liquid-cooled component to the battery module, making the battery module There is a large temperature difference between them, and there is room for improvement. Contents of the invention [0003] The present invent...
