Abstract

A liquid cool pipe and battery system are disclosed. The liquid-cooled pipe comprises a flat pipe and a plurality of flow channels arranged inside the flat pipe; A soaking plate having a lower surfaceat least partially covering an outer wall of the flat tube, and an upper surface of the soaking plate for contacting the battery module and having an area greater than an area covered by the soakingplate. The soaking plate of the present invention covers a plurality of flow channels, is in contact with the battery module and has an area larger than the area covered by the soaking plate on the outer wall, so that the heat exchange area between the battery module and the liquid-cooled pipe on the soaking plate of the liquid-cooled pipe is increased, and a groove is arranged on the upper surface, so that the heat conduction gel can be placed, and the heat dissipation performance of the liquid-cooled pipe is greatly improved. Moreover, the soaking plate and the flat tube are integrated, so that the structure of the liquid cooling pipeline is compact and stable.

Description

technical field [0001] The invention relates to the technical field of power batteries, in particular to a liquid cooling pipeline and a battery system. Background technique [0002] With the increasingly serious energy crisis and environmental pollution, energy conservation and emission reduction have formed a global consensus, and pure electric vehicles have attracted more and more attention. As the only power source for pure electric vehicles, the power battery directly affects the performance and service life of the vehicle. Among all environmental factors, temperature has the greatest impact on the charging and discharging performance of power batteries, and generally the charging efficiency will increase with the increase of temperature. However, when the temperature rises above 45°C, the high temperature will lead to the degradation of the performance of the rechargeable battery material, and the cycle life of the battery will be greatly shortened. When the temperat...
