Experimental investigation of a bottle-sublimation cooler

A bottle-sublimation cooler is an open-cycle cooler of novel design combining the advantages of Joule–Thomson and sublimation coolers. The store of a refrigerant is bottled without heat leakages at ambient temperature. Sublimation of the refrigerant solid phase is the cold-generating process in the cooler. The cooler design and a discovered effect of the solid phase spontaneous capillary-porous structuring provide autoadjustability of the system operational characteristics. The results of experimental investigations of the stored-carbon dioxide bottle-sublimation cooler are reported in this paper. The experimental set-up and procedure of the system principal parameters measurement are covered. Temperature, thermal and overall size-mass parameters of the cooler are measured and reported. Performance specification of the cooler, which had been used for refrigerating of the IR module of a star spectrophotometer during astronomical observations, is presented.
