In most cases cryocoolers use a cryogenic fluid as the working substance and employ moving parts to cycle the fluid around a thermodynamic cycle. The fluid is typically compressed at room temperature, precooled in a heat exchanger, then expanded at some low temperature. See more A refrigerator designed to reach cryogenic temperatures (below 120 K, −153 °C) is often called a cryocooler. The term is most often used for smaller systems, typically table-top size, with input powers less than about 20 kW. Some … See more Gifford-McMahon (GM) coolers have found widespread application in many low-temperature systems e.g. in MRI and cryopumps. Fig.5 is a schematic diagram.
