数据机房热管背板系统极端工况研究

Study of Extreme Condition of Heat Pipe Backboard System in Data Center

热管背板系统在数据机房的散热领域中具有广泛的应用前景。本文主要通过实验对热管背板系统散热性能进行研究,分析背板的进风温度与风量对换热量的影响。对机房的温度场进行模拟分析,结果显示,当热管正常工作时,机房空间温度分布均匀;当机房处于部分热管发生故障的极端工况时,受故障热管的影响,机房运行温度上升,引起部分机柜进风温度超标。采用增大风量的方法来应对极端工况并分析该方法的局限性。

Heat pipe backboard system have a broad prospect in data center heat dissipation.This passage mainly shows the heat dissipation performance of heat pipe backboard system through experiments,finding out the relation between heat release and inlet air temperature.Also,numerical simulation is carried out to analysis the temperature field in data center.Through numerical simulation,temperature filed is uniform when the heat pipes work in good condition.When the system is in extreme condition,temperature of data center will increase,resulting in inlet air temperature out of limits in several racks.It＇s effective to increase air volume of fans but it has its limitation.
