AI Technical Summary

Technical Problem

Traditional circulation pump rotation strategies fail to fully consider pump state differences and step effects, resulting in lifespan asymmetry and system performance fluctuations, affecting the stable operation of data centers.

Method used

By real-time monitoring of the working information of the circulation pump, including gear position, operating time and number of steps, the accumulated loss value is calculated, and the switching timing of the pump is dynamically determined. The high-loss pump is switched first to ensure the balanced life of the pump group and avoid asymmetry problems caused by timed switching.

Benefits of technology

It achieves a balanced extension of the life of the pump group, improves the adaptability and operating efficiency of the liquid cooling system, avoids cooling interruption caused by sudden failure of the circulating pump, and improves the reliability and stability of the system.
