摘　　要：介绍了一种耦合脉管制冷与气波制冷技术的新型制冷机脉管式气波制冷机。分析了脉管式气波制冷机的制冷原理 ,对脉管制冷与气波制冷的耦合性进行了试验研究。同时 ,对振荡管长度、气体分配器的转速等影响脉管式气波制冷机性能的因素进行了试验。通过研究 ,获得了一些有益的结论 。In this paper, a new kind of refrigerator ,pulse tube-gas wave refrigerator, which couples pulse tube refrigeration and gas wave refrigeration is introduced. The principle of the pulse tube-gas wave refrigerator operation is analyzed and the possibility of the coupling of pulse tube and gas wave refrigeration is discussed. The factors, the length of shock tube, the distributor rotor speed and the ratio of gas expanding, which affect the isoentropic efficiency, are studied experimentally. Through the experimental study, some useful conclusions are obtained, and the curves for the factors effecting the isoentropic efficiency are presented.
