摘要
本文从数据中心节能角度、多尺度多模式方面针对降低数据中心的能耗,梳理了机房级、机架级和芯片级冷却的技术进展以及各自特点,总结了目前对数据中心已有的冷却技术发展现状,概述了数据中心目前应用的冷却技术特点和未来的研究趋向。结果表明,芯片级冷却比机房级冷却平均能耗约降低73%,通过对数据中心进行气流组织路线优化,以及液冷门、热管微通道和拓扑结构等的优化,可以增强17.0%~59.7%的冷却能力。
From the perspective of data center energy saving,based on the multi-scale model and multi-aspect to reduce energy consumption,the cooling technology processing and characteristics of the machine room level,rock level and chip level are arranged in this paper.The development of present technology is reviewed,cooling technology characteristics and future research trend are also summarized.It is concluded that the average energy consumption of chip level cooling is about 73%lower than that of machine room level cooling.By optimizing the air distribution route of the data center,the liquid cooling gate,the heat pipe microchannel and the topological structure,the cooling capacity can be increased by 17.0%-59.7%.
