| 摘 要： | 基于简化冷端结构的目的考虑,该文提出了一种“L”型脉管结构取代了通常的“I”型直脉管结构;并在脉管热端采用两个小孔阀分别进行控制脉管热端的进排气量,并对此结构使用有阀氦压缩机驱动,进行初步的试验研究,样机在频率为2.5Hz时,获得72K的冷头最低温度,针对此试验结果进行分析,给出了目前试验样机所存在的问题,提出了进一步改善的方法。

| Abstract: | In order to simplify the pulse tube cold end structure,"L" type pulse tube is used instead of ordinary "I" type pulse tube; and two orifice valves are adopted instead of single orifice at the hot end of pulse tube,which can separately control the mass flow rate of inlet and outlet of pulse tube.Then the performance experiment with valved helium compressor is introduced,experimental result is analyzed,some problems of this machine is shown,and some ways to improve the performance is given. |
