Long-life cryocooler performance and production.

Author(s) : BARR M. C., PRICE K. D., PRUITT G. R.

Summary

Raytheon is currently manufacturing a low rate production lot of long-life cryocoolers to support its internal laboratory needs. The cryocooler being manufactured is an Oxford-class Stirling cycle cryocooler designed to provide more than 3 W heat lift at 60 K with an operational life in excess of eight years. The paper discusses the performance mapping data of the engineering units currently in test. Status of a life test unit representative of this design is reviewed; this life test unit currently has in excess of 35,000 h of operation without a failure. Manufacture of this cryocooler is being implemented in a 2200 sq ft production facility capable of supporting delivery rates in excess of 40 cryocoolers per year.
