摘要： An expander for a concentric pulse tube cooler. The inventive expander includes a central pulse tube; a concentric insulation tube disposed around the central pulse tube, the insulation tube having a concentric chamber therein and the chamber being filled with an insulator and the insulator being atmospheric; and a regenerator disposed around the concentric insulation tube. In a particular implementation, the insulator tube includes a vent which allows the insulation chamber to communicate with the surrounding atmosphere. When used in space, the chamber is filled with a void and the insulator becomes a vacuum and provides effective insulation at cryogenic temperatures. The inventive expander allows for an improved concentric pulse tube cooler design comprising a cold finger assembly disposed at a first end of the concentric pulse tube cooler; a heat exchanger assembly disposed at a second end of the concentric pulse tube cooler; and the pulse tube expander assembly of the present invention secured to the heat exchanger. The expander assembly comprising the central pulse tube; the concentric insulation tube disposed around the central pulse tube having the evacuated insulation chamber therein; and the regenerator disposed around the concentric insulation tube as set forth above.

摘要： A cooling system utilizes a pulse-tube expander having a hollow pulse tube and three hollow regenerator tubes that lie parallel to and laterally displaced from the pulse tube, and are arranged in triangular fashion about the pulse tube. A cold end of each of the regenerator tubes is in gas pressure communication with a cold end of the pulse tube. Pulsing gas pressure is supplied to a warm end of each of the regenerator tubes, and a surge volume communicates with a warm end of the pulse tube. A heat sink is provided at the warm end of the regenerator tubes and the pulse tube to remove heat therefrom and from the pulsing gas. Heat is extracted from a heat load at the cold end of the regenerator tubes and the pulse tube.

摘要： A pulse tube cooler comprising pulse tube, a regenerator concentrically disposed around the pulse tube, and a thermal insulator concentrically disposed between the pulse tube and the regenerator. More specifically, the concentric pulse tube cooler comprises a cold finger assembly disposed at a first end of the concentric pulse tube cooler, a heat exchanger assembly disposed at a second end of the concentric pulse tube cooler that is coupled to a a surge volume and that is coupled to a source of operating gas, and a pulse tube expander assembly slidably and sealably secured to the heat exchanger assembly. The pulse tube expander assembly comprises a central pulse tube, a thermal insulator concentrically disposed around the central pulse tube, and a regenerator concentrically disposed around the concentric insulation tube. The pulse tube expander assembly comprises a slidable axial seal for slidably and sealably securing the pulse tube expander assembly to the heat exchanger assembly. The seal permit relative axial motion between the cold finger and pulse tube expander assemblies and the heat exchanger assembly during cooling of the pulse tube cooler. Vacuum and solid insulation may be employed as the insulation tube.
