摘　　要：设计了一种基于改进PSO-PID控制器的海底数据中心(UDC)液冷装置,通过分析装置的散热性能与冷却液的流动性能,建立电机驱动模型,实时调整管道内部水流速度。同时该装置能够对附着于管道内部的杂质进行自清洁,有效地提高了UDC液冷装置控制系统的性能指标,降低管道内部热量分布不均匀等问题发生的概率。仿真实验结果表明,该液冷装置能够在合理的误差范围内动态调节水流速度,以低能耗获得较为优良的散热效果。A liquid-cooling device for undersea data center(UDC)based on an improved PSO-PID controller was de⁃signed.By analyzing the heat dissipation performance of the device and the flow performance of the coolant,a motor drive model was established to adjust the water flow velocity inside the pipeline in real time.At the same time,the device could self-clean impurities attached to the inside of the pipeline.It could effectively improve the performance indicators of the UDC liquid cooling device control system and reduce the probability of problems such as uneven heat distribution inside the pipeline.The simulation experimental results show that the liquid cooling device can dynamically adjust the water flow velocity within a reasonable error range,achieving excellent heat dissipation effect with low energy consumption.
