Reversible cycle piston-pulse tube cryocooler.

Author(s) : JOHNSON A. L.

Summary

The replacement of the orifice and reservoir elements of a fixed orifice pulse tube cryogenic refrigerator with an expander piston results in a reversible cycle pulse tube machine. A generalized lumped parameter model of thermally regenerated engines has been developed and programmed to predict the comparative thermodynamic performance of Alpha type Stirling cycle, fixed and modulating orifice pulse tube, and piston-pulse tube machines. The basis of the analytical model and computer program, the results of the computer analysis, a preliminary design of the flexure supported dual piston integrated compressor-displacer engine, and a schematic of the fluid circuit required for phase shift control is presented.
