  • Multi-stage pulse tube cryocooler with acoustic impedance constructed to reduce transient cool down time and thermal loss
    Patent number: 7437878
    Abstract: The cool down time for a multi-stage, pulse tube cryocooler is reduced by configuring at least a portion of the acoustic impedance of a selected stage, higher than the first stage, so that it surrounds the cold head of the selected stage. The surrounding acoustic impedance of the selected stage is mounted in thermally conductive connection to the warm region of the selected stage for cooling the acoustic impedance and is fabricated of a high thermal diffusivity, low thermal radiation emissivity material, preferably aluminum.
    Type: Grant
    Filed: August 23, 2005
    Date of Patent: October 21, 2008
    Assignee: Sunpower, Inc.

  • High performance thin film alkali metal thermoelectric device
    Patent number: 5039351
    Abstract: An alkali metal thermoelectric conversion device formed from a porous tube or plate coated with a thin film of beta-alumina, the porous tube or plate is sintered metal or metal alloy having a coefficient of thermal expansion which approaches that of the beta-alumina to form a mechanically stable device with high electrical output.
