摘要
采用有限时间热力学、㶲方法分析了水冷多联热管系统(MSHPS)。计算结果表明,IT服务器应该集中安排在1.3m以下的位置。CDU在6s的时间内具有约74J的传热量。最佳流量时CDU的速率为0.82kg/s。计算了免费冷却时间,部分免费冷却时间。并分析了中国主要城市的节能潜力从61%到25%。研究结果对其他管网系统实际应用具有重要意义。
Thefinite time thermodynamic analysis,the exergy method were employed to build the simulation model of the combined system of water cooled multi-spilit heat pipe system(MSHPS)used in data center.The results show that the IT servers should concentrate on arranging at the location below 1.3 m.The CDU has a heat transfer of about 74 J in a period of 6 s.And the optimumflow rate of the CDU is 0.82 kg/s.Then the free cooling time,part time free cooling and energy saving potential in major cities of China were analysised.The energy saving potential is from 61%to 25%.The results are of great significance for the operational control and practical application of other pipe-net systems.
