摘 要 本文提出了一种数据中心泵驱两相双环路散热系统，该系统结合了芯片冷板液冷散热技术和机房泵驱环路热管风冷散热技术，采用两套单独的氟泵环路热管，可分别对服务器中的CPU和其他发热元件散热。本文阐述了该散热系统的基本原理，并完成了含有IT功率为10kW的单机柜机房的改造和测试。测试机房位于湖北省襄阳市，于2022年2月开始进行连续的服务器满负载测试。分别选取了不同季节各一日的测试数据进行分析，实测数据显示机房在冬季工况下日平均散热PUE为1.06，在过渡季工况下日平均散热PUE为1.10，夏季工况下日平均散热PUE为1.18。利用实测数据采用内插和外推的数学方法预估了该机房全年逐时的能耗情况，预测结果显示该机房全年平均散热PUE为1.11。

Abstract A pump drive two-phase dual-loop heat dissipation system for data center is proposed. The system combines chip cold plate liquid cooling method and pump-driven loop heat pipe air cooling method. Through two sets of pump drive thermosyphon, CPU and other components in the server can achieve efficient heat dissipation. The principle of the system is described, and a 10kW actual single rack data room located in Xiangyang, Hubei had been transformed and tested. The actual operation data shows that the heat dissipation PUE of the data room in typical working conditions is 1.06 in winter, 1.10 in transition season and 1.18 in summer. Using the measured data, the mathematical method of interpolation and extrapolation is used to predict the hourly energy consumption of the data room throughout the year, and the annual average heat dissipation PUE of the data room is predicted to be 1.11.
