Abstract
A cryogenic cooler of the pulse tube type is provided wherein the reservoir is disposed within the compressor housing. The invention provides the high efficiencies associated with orifice pulse tube cryogenic coolers, but is more compact and is generally lighter in weight than conventional pulse tube cryogenic coolers.
Claims11
A cryogenic cooler of the orifice pulse tube type comprising:
- (a) an electromechanical compressor disposed within a compressor housing;
- (b) a regenerator disposed in fluid tight communication with the compressor;
- (c) a pulse tube having a proximal end in fluid tight communication with the regenerator and a distal end defining an orifice, the pulse tube being disposed external of the compressor housing;
- (d) a reservoir disposed in fluid tight communication with the distal end of the pulse tube via the orifice;
- and
- (e) heat transfer means for transferring heat from a cooling load to the cryogenic cooler;
- (f) heat removal means for removing heat from the pulse tube cooler;
- wherein the reservoir is disposed within the compressor housing.

A cryogenic cooler of the orifice pulse tube type comprising:
- (a) an electromechanical compressor disposed within a compressor housing;
- (b) a regenerator;
- (c) a pulse tube disposed external of the compressor housing;
- (d) a reservoir;
- (e) an aftercooler heat exchanger disposed in fluid tight communication between the compressor and the regenerator, the after cooler being adapted to remove heat from the cryogenic cooler and discharging that heat to a heat sink;
- (f) a cooling load heat exchanger disposed in fluid tight communication between the regenerator and the pulse tube, the cooling load heat exchanger being adapted to transfer heat from a cooling load to the cryogenic cooler;
- and
- (g) a hot side heat exchanger disposed in fluid tight communication between the pulse tube and the reservoir;
- wherein the reservoir is disposed within the compressor housing.
