  • Vibrationally isolated stirling cooler refrigeration system
    Patent number: 6422025
    Abstract: A vibration isolation system for operating a Stirling cooler within an enclosure. The system may include a number of linkages for connecting the Stirling cooler to the enclosure. The system may further include a balance mass connected to the Stirling cooler by a balance mass spring. The balance mass also may be used to operate a pump based upon the vibrations produced by the Stirling cooler.

  • Refrigerator with interior mounted heat pump
    Patent number: 5642622
    Abstract: A refrigerator having a heat pump mounted within the insulated portion of the refrigerator cabinet which is cooled by the heat pump. The heat pump is a Stirling cycle or Rankine cycle heat pump, is used to cool the interior of the refrigerator cabinet, and is mounted in an insulated housing to limit the transfer of heat from the heat pump into the refrigerator cabinet. A heat transporting conduit connects the heat pump to an exterior heat exchanger mounted outside the refrigerator cabinet.
