摘要:

数据中心的功率密度不断增加,为保障设备平稳运行和引导绿色健康发展,数据中心散热问题成为重大挑战。液冷技术可以有效解决机房高密度部署和机房局部过热的问题,其中浸没式液冷因突出的散热和节能优势近年来得到广泛关注。对单相和相变两种典型浸没液冷方式进行了介绍,并围绕两种方式下的冷却液关键问题进行了探讨,重点分析了碳氢及有机硅冷却液和碳氟冷却液的性能和应用差异,及其对安全和环境的影响。

Abstract:

As the power density of data centers increases, heat dissipation becomes a major challenge to ensure the smooth running of devices and promote green and healthy development of data centers. Liquid cooling technology can effectively solve the problems of high-density deployment and partial overheating of the machine room, among which immersion liquid cooling technology has been widely considered because of its outstanding heat dissipation and energy saving advantages. In this paper, two typical immersion liquid cooling modes of single phase and phase change are introduced, the key issues of the coolant under the two modes are discussed, also the performance and application differences of hydrocarbon, organosilicon and fluorocarbon compounds, as well as their impacts on safety and environment are emphatically analyzed.

Key words: data center, immersion liquid cooling, liquid coolant
