摘　　要：近年来,热管背板空调在数据中心的应用需求已呈爆炸式增长,其对于降低数据中心局部热点、实现高热密度机柜冷却、降低数据中心能源利用效率(Power Usage Effectiveness,PUE)具有十分重要的意义,是机房单位面积内高热密度部署的最佳选择。热管背板空调粗放式应用过程中,未对热管最佳充液率做明确约束。通过理论模拟计算及实验研究发现,热管背板系统制冷量随热管充液率呈先上升后下降的趋势,最佳充液率为70%左右,合理的充液率可使制冷量至少提升6.5%,同时还可减少20%以上的制冷剂投资成本,是数据中心节能减排的一大方向。In recent years,the application demand for heat pipe backplane air conditioners in data centers has exploded.The heat pipe backplane air conditioner is of great significance for reducing local hot spots in the data center,achieving high heat density cabinet cooling,and reducing the Power Usage Effectiveness(PUE)of the data center.It is the best choice for high heat density deployment per unit area of the computer room.During the extensive application of heat pipe backplane air conditioning,there is no clear restriction on the optimal refrigerant charge rate of the heat pipe.In this paper,through theoretical simulation calculations and experimental research,it is found that the energy efficiency of the heat pipe backplane system first rises and then decreases with the heat pipe refrigerant charge rate,and the best filling rate is about 70%.A reasonable charging rate can increase the cooling capacity by at least 6.5%,and at the same time can reduce the investment cost of refrigerant by more than 20%,which is a major direction for energy saving and emission reduction in data centers.
