| 英文摘要 | This paper presents experimental results on a novel two-stage gas-coupled vm-pt cryocooler, which is a one-stage vm cooler coupled a pulse tube cooler. in order to reach temperatures below the critical point of helium-4, a one-stage coaxial pulse tube cryocooler was gas-coupled on the cold end of the former vm cryocooler. the low temperature inertance tube and room temperature gas reservoir were used as phase shifters. the influence of room temperature double-inlet was first investigated, and the results showed that it added excessive heat loss. then the inertance tube, regenerator and the length of the pulse tube were researched experimentally. especially, the dc flow, whose function is similar to the double orifice, was experimentally studied, and shown to contribute about 0.2 k for the no-load temperature. the minimum no-load temperature of 4.4 k was obtained with a pressure ratio near 1.5, working frequency of 2.2 hz, and average pressure of 1.73 mpa.
