AI Technical Summary

Technical Problem

The thermal management system of existing battery modules has problems such as low heat dissipation efficiency, uneven heat dissipation and reduced coolant circulation efficiency, which is particularly obvious in large-scale battery modules.

Method used

A battery module balanced liquid cooling system is designed. By setting liquid cooling pipe channels at equal intervals in the liquid cooling mandrel, and using the unique connection method of the U-shaped liquid cooling pipe and the liquid cooling pipe connection assembly, the efficient circulation and uniform distribution of the coolant is achieved. At the same time, a balanced liquid-cooled flow control method is proposed. Through precise calculation and partitioned flow distribution, the flow rate of each liquid-cooled pipe channel is ensured to match its heat dissipation needs.

Benefits of technology

It significantly improves the heat dissipation efficiency and uniformity of the battery module, effectively avoids local overheating problems, extends battery life, and improves the safety and reliability of the battery module.
