ABSTRACT:
A self-cooling Stirling cycle cooler (1). The cooler (1) includes a conduit (20) for transporting thermal energy from a first location to a second location. The conduit is a closed loop having first and second ends terminating in a first chamber (29). A pump (14) is mounted in the first chamber (29) for moving the heat energy therein from the first location to the second location. The pump (14) includes a piston (40) which reciprocates in the first chamber (29). A first valve (42) is provided for controlling the direction of a flow of fluid in the conduit (20) into the first chamber (29) and a second valve (46) for controlling the flow of the fluid in the conduit (20) out of the first chamber (29). In a Stirling cycle cooler, the balancer mass is used as the pump piston to facilitate the movement of fluid in the conduit. By utilizing the balancer mass of a Stirling cycle cooler, self-cooling is effected with minimal additional hardware, weight and cost.
