基于LHP的数据中心服务器芯片级散热技术
Server chip-level cooling technology in data center based on LHP
摘要
Abstract
To solve the needs of high-efficiency heat dissipation and energy conservation for green data centers,an investigation about the server chip-level cooling technology in data center based on loop heat pipe(LHP)was explored.The high performance LHPs applied in real servers and their application tests at varied condenser temperature were initiatively developed and experimented.The experimental results show that,compared to traditional fin-heat-sinks working at the same test conditions,the water-cooling LHP can decrease the case temperature of server chips about 29～32℃and the air-cooling LHP can reduce the case temperature of server chips about 29～30℃.These conclusions are helpful to increase the temperature of supply water and supply wind in data center,which makes a possibility of cutting down the energy use of cooling system dramatically in data center.Meanwhile,the noise value of whole server by using LHP chip-level cooling can decrease about 25～30 dB,which is beneficial for the friendliness of man-machine environment.关键词
