Description
A high efficiency single-stage Stirling-type coaxial pulse tube cryocooler (PTC) operating at around 40 K has been developed based on numerical simulation by SAGE software and previous experiment experience. The double-inlet and the inertance tubes together with the gas reservoir were adopted as the phase shifters. Under the conditions of 2.5 MPa charging pressure and 30 Hz frequency, the prototype has achieved a no-load temperature of 23.68 K with 330 W electric input power rejecting at 279 K. It can provide 5 W cooling capacity at 40 K when electric input power increases to 395 W, and 7.56% of Carnot efficiency has been realized. It only takes 11 minutes for the PTC to lower its no-load temperature at the cold end from 295 K to 40 K.
