数据中心热管理的下一个根本性变化是从传统的冷却方法（如空气冷却）转向直接液体冷却，以实现高热质量和相应的卓越冷却。在过去几年中，数据中心有限地采用了直接液体冷却，因为它简单且散热能力强。单相工程流体浸入式冷却还有其他一些好处，比如更好的服务器性能，更均匀的温度分布，更高的机架密度，以及在不需要电气隔离的情况下冷却服务器中所有组件的能力。这种冷却技术的可靠性方面在公开文献中还没有得到很好的解决。本文介绍了全单相介质流体浸入式伺服器在环境室宽温度范围内的性能。服务器被放置在一个环境室中，在100%相对湿度下，温度范围从- 20°C到10°C，在恒定的50%相对湿度下，温度范围从20°C到55°C，持续很长时间。这项工作是第一次尝试测量服务器和其他组件的性能，如泵，包括流量下降，启动故障，以及在极端气候条件下完全液体淹没系统的其他潜在问题。泵送功耗与数据中心的运营成本成正比。实验一直进行到芯温达到最大结温为止。该实验有助于确定阈值容量和服务器在极端气候条件下应用的鲁棒性。
The next radical change in the thermal management of data centers is to shift from conventional cooling methods like air-cooling to direct liquid cooling to enable high thermal mass and corresponding superior cooling. There has been in the past few years a limited adoption of direct liquid cooling in data centers because of its simplicity and high heat dissipation capacity. Single-phase engineered fluid immersion cooling has several other benefits like better server performance, even temperature profile, and higher rack densities and the ability to cool all components in a server without the need for electrical isolation. The reliability aspect of such cooling technology has not been well addressed in the open literature. This paper presents the performance of a fully single-phase dielectric fluid immersed server over wide temperature ranges in an environmental chamber. The server was placed in an environmental chamber and applied extreme temperatures ranging from −20 °C to 10 °C at 100% relative humidity and from 20 to 55 °C at constant 50% relative humidity for extended durations. This work is a first attempt of measuring the performance of a server and other components like pump including flow rate drop, starting trouble, and other potential issues under extreme climatic conditions for a completely liquid-submerged system. Pumping power consumption is directly proportional to the operating cost of a data center. The experiment was carried out until the core temperature reached the maximum junction temperature. This experiment helps to determine the threshold capacity and the robustness of the server for its applications in extreme climatic conditions.
