Design of a large-capacity multi-piston pulse tube cryocooler

摘要: ercial high temperature superconductors, two designs for a pulse tube cryocooler have been developed. In the first design, three parallel-arrayed inertance cryocoolers are driven by one twinopposed linear compressor. It is hard this system to obtain relative Carnot efficiency of higher than 25%. other it includes and compressors. The reservoir each omitted. compression chamber compressor connected in series through expansion another With configuration, acoustic work coming out secondary water-cooled heat exchanger can be recovered much easier better field, so could 35%. should best candidates superconductor power grid.
