摘要： A cryogenic refrigerator for cooling a rotating device includes a stationary regenerator, and a rotatable cold heat exchanger coupled to the stationary regenerator to rotate relative thereto. The cryogenic refrigerator is, for example, of the Gifford-McMahon type or pulse tube type. In the Gifford-McMahon type, a stationary cylinder houses the regenerator, and a rotatable cylinder mounted to the cold heat exchanger is concentrically arranged about the stationary cylinder. Alternatively, the rotatable cylinder is axially offset of the stationary cylinder. A seal, for example, a ferrofluidic seal, is located between the stationary and rotatable cylinders. In the pulse-tube type, a pulse tube is concentrically arranged about the regenerator, and the cold heat exchanger includes a stationary portion coupled to the regenerator and a rotatable portion coupled to the pulse tube. A back-up valve system is provided for increased reliability.

摘要： A cryogenic cooling system is configured to control the flow of a heat transfer fluid through a remote thermal load, such as a superconducting magnet or rotor. The cryogenic cooling system includes a refrigerator including a cryogenically cooled surface and a cryogenic fluid transport device disposed for circulating a heat transfer fluid between the cryogenically cooled surface and the remote thermal load. The cryogenic fluid transport device advantageously serves as device for providing the necessary mechanical force necessary to move the heat transfer fluid from the cryogenically cooled surface (e.g., end of a cryocooler) to the remote thermal load. Thus, unlike conventional cooling arrangements the heat transfer fluid does not require a phase change.

摘要： A cryogenic cooling system is configured to control the flow of a heat transfer fluid through a remote thermal load, such as a superconducting magnet or rotor. The cryogenic cooling system includes a refrigerator including a cryogenically cooled surface and a cryogenic fluid transport device disposed within the refrigerator for circulating a heat transfer fluid between the cryogenically cooled surface and the remote thermal load. The cryogenic fluid transport device being positioned within the refrigerator advantageously serves as device for providing the necessary mechanical force necessary to move the heat transfer fluid from the cryogenically cooled surface (e.g., end of a cryocooler) to the remote thermal load. Thus, unlike conventional cooling arrangements the heat transfer fluid does not require a phase change.

摘要： A combination refrigerator and current lead assembly includes a pulse tube having a cold end and a warm end. A first electrical connector is attached to the warm end. A second electrical connector attached to the pulse tube supplies current to a lead, for example, a high temperature superconductor lead. The assembly includes a second pulse tube having an electrical connector attached at its warm end and a second electrical connector for supplying current to a lead. The second electrical connectors are attached to the cold ends of the pulse tube. The pulse tubes are formed from an electrically conductive material. An electrical isolator electrically isolates the pulse tubes from each other. Additional electrical isolators electrically isolate the pulse tubes from a compressor, valve, and regenerators of the system.

摘要： A superconducting coil assembly is of the type mounted to a rotor assembly of an electric rotating machine and, in operation, is maintained at cryogenic temperatures while the portion of the rotor assembly is maintained above cryogenic temperatures. The superconducting coil assembly includes at least one superconducting winding wound about a longitudinal axis of the coil assembly and having an inner radial surface defining a bore extending through the coil assembly. The coil assembly also includes at least one support member extending across the bore and mechanically coupled to the portion of the rotor assembly and to opposing portions of the inner radial surface of the at least one superconducting winding.

摘要： A detachable work extraction system includes an expansion engine including a self-sealing coupling adapted to detachably connect the expansion engine to a cold box, and a hydraulic work extractor operatively connected to the expansion engine. A gas can travel from the cold box to the expansion engine through the self-sealing coupling. The gas is cooled by expansion of the gas in the expansion engine and work produced by the expansion of the gas is dissipated by the hydraulic work extractor. The expansion engine includes a cylinder housing a piston. The cylinder has a first self-sealing coupling defining an inlet and a second self-sealing coupling defining an outlet. The first and second self-sealing couplings each have a spring loaded seal. In the absence of an external force applied to the seal, the seal prevents flow of gas through the couplings.

摘要： An HTS cable assembly is provided which includes a cryostat or housing, an HTS wire bundle disposed longitudinally within the cryostat, and plural support members disposed between the HTS wire bundle and the cryostat. The support members are elongate, tubular members having resiliency in both the axial and radial directions. The support members are disposed between the HTS wire bundle and the inner surface of the cryostat in an arrangement that maintains and supports the HTS wire bundle in a spaced-apart relationship with respect to the inner surface of the cryostat. In addition, the plural support members are configured to substantially prevent relative movement between the HTS wire bundle and the cryostat.
