Review of experimental research on Joule-Thomson cryogenic refrigeration system

With the increasing miniaturization of high-powered electronic components, technologies for rapid cooling in small spaces have received more and more attention. Joule-Thomson (J-T) refrigeration is an effective means for rapid cooling. It is widely used in military and medical refrigeration, electronic equipment cooling and many other fields. This paper describes the structural development of J-T refrigerators of the traditional Hampson type, etched microchannel type and others. It reviews experimental studies on refrigeration components and the charge composition of the mixtures in the J-T cryogenic system. It also introduces the main applications of the J-T cryogenic system. Finally, it summarizes the above research and puts forward developmental prospects, hoping to provide reference for future experimental design and research.
