| Abstract | Small capacity Stirling cryocoolers for space-borne applications generally use linear electromagnetic drives (also called linear motors) for long life, maintenance free operation and high reliability. Such motors are normally of moving coil type. The performance prediction of such miniature Stirling cryocoolers is very critical and is governed by principal design parameters. The performance of a cryocooler depends on various losses such as loss due to regenerator ineffectiveness, temperature swing loss, shuttle conduction loss, P-V loss, etc. In this paper, the optimization of a cold head for a given opposed piston compressor has been carried out considering above losses using cyclic simulation and with COP and refrigerating effect as optimization parameters for a cold head temperature of 70 K. |
