Progress on the development of miniature turbomachines for low capacity reverse-Brayton cryocoolers.

Author(s) : MCCORMICK J. A., SWIFT W. L., SIXSMITH H.

Summary

Developments are being carried out to extend the practical use of turbomachine-based reverse-Brayton cycle cryocooler technology to lower capacity applications. These developments focus primarily on cooling loads in the range of 0.35 to 2 watts at temperatures from about 35 to 70 K in a single stage cycle with neon. The critical components for a low capacity reverse-Brayton cycle cryocooler include the expansion turbine and the turbo-compressor. Advanced designs presently under development for both components use high speed gas bearings and high energy permanent magnets for electromechanical energy conversion.
