AI Technical Summary

Technical Problem

In existing technologies, uneven heat dissipation in battery packs leads to inconsistent temperature distribution, affecting their performance and lifespan.

Method used

A cold plate structure is designed, including a first plate and a second plate, and is provided with a first liquid inlet channel, a second liquid inlet channel and a liquid return channel. Through the combination of the liquid inlet, the liquid outlet, the first cover plate and multiple through holes, a complex medium flow path is formed, which increases the flow resistance of the medium in the cold plate structure, thereby improving the temperature uniformity.

Benefits of technology

This achieves uniform cooling of the battery components, improves the temperature uniformity of the battery, extends the battery's lifespan, and enhances the stability and safety of the equipment.
