The Liquid Cooled Load Bank adopts liquid circulation cooling instead of traditional air cooling heat dissipation, with extremely high heat dissipation efficiency, no noise, and excellent dust and moisture resistance. The equipment has strong overall sealing performance, which is suitable for high-power and long-term continuous full-load testing conditions. It completely solves the problems of excessive temperature, high noise, easy dust accumulation and uneven heat dissipation of traditional air-cooled load banks during high-power operation. It is mainly used for high-power aging testing and full-load durability testing of large generators, high-voltage energy storage systems, large UPS and data center power supply equipment, suitable for high-end scenarios such as harsh field working conditions, silent computer room operation and maintenance, and long-term uninterrupted testing.
