ABSTRACT:
A resonantly coupled .alpha.-Stirling cooler has hot and cold variable-volume chambers, a regenerator, and a driver for maintaining reciprocating gas displacement between the chambers. Only the hot side of the cooler is driven; the cold side responds passively by resonant coupling. The phase difference between volume oscillations in the hot and cold variable-volume chambers are altered by adjusting the driving frequency.
