摘要： A cryocooler system comprising a heat exchanger for cooling a compressed returning warmed cryogenic fluid stream, the heat exchanger having a bypass loop to produce a major stream and a minor stream exiting the heat exchanger. The minor stream is further cooled by expansion and used as a heat exchange medium for an external heat load after which it is compressed and returned to the heat exchanger for heat exchange with the compressed return warmed cryogenic fluid stream. The major stream is further cooled by expansion and recirculated to the heat exchanger to cool the compressed returning warmed cryogenic fluid stream. The major stream and minor stream are combined either inside or outside of said heat exchanger to form the warmed cryogenic fluid inlet stream for compression.
