Description

technical field

[0001] The invention relates to a battery heat management device, in particular to a single-channel sealed connection device for circulating heat management liquid. Background technique

[0002] The battery thermal management device is an important part of the battery system, which ensures that the battery system works under optimal temperature conditions. The battery thermal management device in the prior art usually consists of an independently distributed battery thermal management internal and external communication mechanism (common name: flange sealing joint of the water pipe of the battery pack box, referred to as "flange joint") and a thermal management liquid temperature acquisition sensor. In addition, the temperature acquisition sensors are usually arranged in the manner of arranging a single temperature sensor on a single-channel pipeline.

[0003] The existing structure and layout of flange joints and temperature sensors mainly have the followin...
