Possibility of a Commercial Stirling Cryocooler Down to 77 K

Graphical Abstract

Abstract

Abstract

An original commercial Stirling cryocooler named Cryo-S 100 with performance of 33 W cooling power@193 K and no-load cooling temperature 91 K.Based on a Sage model of Cryo-S 100 Stirling cryocooler,the calculation results showed that it could be improved to liquid nitrogen temperature range when the length of cold tip simply extended twice.The elongated cooler obtained 2.0 W@77 K with electric input power of 120 W by experiment.
