我们提出了一种具有自然对流的液浸冷却技术，用于数据中心的大功率服务器板，具有较高的冷却效率。通过CFD模拟和实际实验对冷却性能进行了评价。作为制冷剂，使用了几种非导电、热稳定和化学稳定的液体，包括硅油、大豆油和全氟化碳结构液体。制冷剂中的CPU温度随制冷剂的瑞利数单调降低。更平滑的制冷剂更适合冷却高功率CPU。 当CPU的结温上限为98摄氏度（208华氏度）时，发现120瓦级CPU可以冷却。这表明，该技术可以应用于每个浴缸超过10千瓦的冷却系统。因此，这种自然对流的拟议技术在低能耗和节省空间的电路板冷却方面显示出了巨大的潜力，其电力使用效率（PUE）低于1.04。引文:2018年冬季会议，伊利诺伊州芝加哥，会议论文

We proposed a liquid immersion cooling technology with natural convection for high power server boards used in data centers with high cooling-efficiency. The cooling performance was evaluated by CFD simulation and actual experiments. As the refrigerants, several non-conductive, thermally and chemically stable fluids were applied, including silicone oil, soybean oil, and perfluorocarbon structured liquids. The CPU temperature in the refrigerant monotonically decreases with the Rayleigh numbers of the refrigerant. The smoother refrigerant is better for cooling the high power CPU. When the upper limit of the junction temperature of the CPU was 98 degrees C (208 degrees F), it was found that 120 W class CPUs can be cooled down. This shows that the technology can be applyed for cooling system with exceeding 10 kW per bath tub. As a result, this proposed technology with natural convection exhibits promising potential for low energy and space-saving board cooling which demonstrates a Power Usage Efficiency (PUE) below 1.04.
