AI Technical Summary

Technical Problem

Existing energy storage PCS converters suffer from low efficiency, high noise, and fan failure due to fan cooling. Furthermore, as power increases, the temperature of inductors and power devices rises, affecting lifespan and safety.

Method used

The system employs liquid cooling, with coolant circulating through a liquid cooling plate and electrical components installed there. The enclosure and liquid cooling plate are sealed together to form an independent placement area. Inductors are placed in a relatively independent area to reduce heat interference. Coolant flow is used for heat dissipation, and the design of the partition area and cable routing channels enhances heat dissipation efficiency.

Benefits of technology

It achieves efficient and stable heat dissipation, reduces the interference of inductor heat on other electrical components, improves the service life and safety of the equipment, reduces noise, and meets the requirements for long-term stable operation.
