将服务器完全浸没在介电矿物油中已成为一种很有前途的技术，可以最大限度地减少数据中心的冷却能耗。然而，由于缺乏足够的公开数据和油浸冷却性能的长期文档，大多数数据中心运营商对将这些方法应用于其关键任务设施犹豫不决。在本研究中，将单个服务器完全水平浸入矿物油中。通过实验观察了不同体积流量和进油温度对服务器热性能和功耗的影响。具体来说，在稳态条件下记录了中央处理器（cpu）、主板（MB）组件和散装流体的温度测量。这些结果提供了适合油浸数据中心的环境条件的初始边界包络。与传统空气冷却的基准测试结果相比，该技术显示系统的热阻降低了34.4%。总体而言，冷却回路能够实现低至1.03的部分功率使用效率（pPUECooling）值。这项服务器级别的研究提供了利用高温、低流量油进行冷却可能节省的设施能源的预览。还讨论了优化信息技术（IT）硬件和实施油冷却的其他机会。
Complete immersion of servers in dielectric mineral oil has recently become a promising technique for minimizing cooling energy consumption in data centers. However, a lack of sufficient published data and long-term documentation of oil immersion cooling performance make most data center operators hesitant to apply these approaches to their mission critical facilities. In this study, a single server was fully submerged horizontally in mineral oil. Experiments were conducted to observe the effects of varying the volumetric flow rate and oil inlet temperature on thermal performance and power consumption of the server. Specifically, temperature measurements of the central processing units (CPUs), motherboard (MB) components, and bulk fluid were recorded at steady-state conditions. These results provide an initial bounding envelope of environmental conditions suitable for an oil immersion data center. Comparing with results from baseline tests performed with traditional air cooling, the technology shows a 34.4% reduction in the thermal resistance of the system. Overall, the cooling loop was able to achieve partial power usage effectiveness (pPUECooling) values as low as 1.03. This server level study provides a preview of possible facility energy savings by utilizing high temperature, low flow rate oil for cooling. A discussion on additional opportunities for optimization of information technology (IT) hardware and implementation of oil cooling is also included.
