AI Technical Summary

Technical Problem

The flow field temperature uniformity of existing liquid-cooled plate components in the battery pack is poor, resulting in the coolant temperature of the battery cell being generally higher or lower than the other side on one side between two adjacent liquid-cooled plates, affecting the Battery life.

Method used

Design a kind of liquid cold plate component, where the two adjacent liquid cold plates and the liquid rushway and return liquid flow tract are arranged in the third direction. The coolant flows through the cross to avoid uneven temperature.

Benefits of technology

By staggered the flow channel structure, the temperature uniformity of the coolant is improved, and the service life of the battery is extended.

Abstract

The utility model relates to a liquid cooling plate assembly, a battery pack and a power utilization device, and the liquid cooling plate assembly comprises at least two liquid cooling plates which extend along a first direction and are arranged at intervals in a second direction, and each liquid cooling plate comprises a liquid inlet flow channel and a liquid return flow channel; in two adjacent liquid cooling plates, the liquid inlet flow channel and the liquid return flow channel of one liquid cooling plate and the liquid inlet flow channel and the liquid return flow channel of the other liquid cooling plate are arranged in a staggered manner in a third direction; wherein the first direction, the second direction and the third direction are perpendicular to one another. According to the liquid cooling plate assembly, the condition that the temperature of the cooling liquid on one side (above) of the battery cell located between two adjacent liquid cooling plates in the third direction is generally higher or lower than the temperature of the cooling liquid on the other side (below) is avoided, and the temperature uniformity is improved, so that the service life of the battery cell is prolonged.
