IIR documentSummary
Many recent advances in both recuperative and regenerative cryocoolers are discussed. Temperatures above 4 K are the primary focus of the review. Applications for such cryocoolers are presented and the requirements which these applications impose on the cryocoolers are reviewed. Recent developments to meet some new requirements include the use of flexure and gas bearings to eliminate the moving displacer in compressors and displacers, pulse tube refrigerators to eliminate rubbing contact in Stirling refrigerators, the use of gas mixtures to improve efficiency of Joule-Thomson refrigerators, and the use of sorption compressors and thermoacoustic drivers to replace mechanical compressors and pressure oscillators.
