Experimental investigation of a mixed-refrigerant Joule-Thomson cryocooler in the 70 to 100 K temperature range.

Author(s) : LUO E. C., GONG M. Q., ZHOU Y.

Summary

The experimental system of a closed cycle Joule-Thomson cryocooler with a special mixture driven by a one-stage oil-lubricated air-conditioning compressor is established. Two types of miniature counterflow heat exchanger used in the Joule-Thomson cryocooler are tested. The lowest temperature of 67.5 K is achieved. Typically, the cryocooler can successfully operate in 70-100 K temperature ranges with more than 2 watts at 80 K.
