摘　　要：根据高性能计算机全天候温控的需要,提出了综合应用蒸气压缩和动力型分离式热管制冷技术的复合冷源方案。在冬季及春、秋过渡的低温季节,运行热管循环不仅大幅降低环控装置的能耗,而且可以避免在低温环境运行压缩式制冷易发生的冷启动、回油润滑等问题。提出了蒸气压缩制冷、蒸气压缩/热管复合制冷和热管制冷的分区工作模式,引入复合制冷模式有效拓宽了热管运行温区,大幅提高了制冷系统的综合COP。模拟分析了在北京地区应用热管复合制冷技术的节能性能,相比常规的压缩制冷节能率高达40%。研究表明:热管复合制冷系统具有显著的节能减排优势,特别适用于全天候工作的机房、基站等高热密度电子集成系统的温控。Based on the need of all -weather environment control system of high -performance computer, a composite cool- ing source system scheme which combines traditional refrigeration with mechanically driven separating type heat pipe was pro- posed. When outdoor temperature was below the temperature preset in some low - temperature seasons, the heat pipe technology not only could reduce the energy consumption of cooling source system efficiently, but also avoid some problems such as cold start and oil retrieving lubrication, which were caused by vapor compression refrigeration system. Base on the simulation, operating mode of the system was divided into 3 modes of vapor compression refrigeration mode, composite refrigeration with heat pipe mode and heat pipe mode. The operating range of the heat pipe system was extended because of the appearance of composite refrigera- tion ; the COP of cooling source system increased significantly. Compared with traditional cooling source system, the composite sys- tem which was simulated and analysed in Beijing can save about 40% of energy consumption. The study shows that composite cool- ing source system with heat pipe system is particularly applicable to all - weather environment control system of high density elec- tronic integrated system, for example, high -performance computer and base station.
