Abstract

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
