AI Technical Summary

Technical Problem

Existing power battery liquid cooling devices cannot quickly conduct local high temperatures through a single heat dissipation path during high-power charging and discharging, resulting in uneven coolant flow, insufficient heat dissipation in some flow channels, waste of resources, and inability to achieve overall uniform heat dissipation.

Method used

The heat dissipation structure combines heat-conducting fins and a cooling fan. The heat-conducting fins conduct battery heat through aluminum alloy, while the serpentine coolant pipes improve heat dissipation efficiency. The fan, in conjunction with the air guide frame, directs airflow to remove heat, achieving efficient heat dissipation through a combination of air cooling and liquid cooling.

Benefits of technology

It achieves rapid and uniform heat dissipation of the battery, avoids local overheating, improves cooling efficiency, and ensures battery safety and lifespan.
