摘　　要：建立热耦合二级Stirling型脉管制冷机实验装置。通过实验,系统研究了交变流动工质的工作频率和平均工作压力对热耦合二级Stirling型脉管制冷机性能的影响,详细报道并分析讨论了实验结果。以氦气作为工质,在优化工作频率和平均工作压力条件下,热耦合二级Stirling型脉管制冷机获得了13.52 K的无负荷制冷温度。An experimental apparatus of a thermally coupled two-stage Stirling-type pulse tube refrigerator has been established.The influences of operating frequency and mean working pressure on the refrigeration performance are experimentally investigated.The experimental results are reported and discussed.Using helium as working fluid and under the conditions of the optimized operating frequency and mean working pressure,a no-load cooling temperature as low as 13.52 K has been achieved by the prototype.
