    Droplet Evaporator For High-Capacity Heat Transfer (1993)
    In:  Other Sources
    Details
    Publication Date: 2019-07-12
    Description: Proposed heat-exchange scheme boosts heat transfer per unit area. Key component is generator that fires uniform size droplets of subcooled liquid at hot plate. On impact, droplets spread out and evaporate almost instantly, removing heat from plate. In practice, many generator nozzles arrayed over evaporator plate.

    Miniature Gas-Circulating Machine (1993)
    In:  Other Sources
    Details
    Publication Date: 2019-07-12
    Description: Proposed gas-circulating machine consists essentially of centrifugal pump driven by induction motor. Noncontact bearings suppress wear and contamination. Used to circulate helium (or possibly hydrogen or another gas) in regeneration sorption-compressor refrigeration system aboard spacecraft. Also proves useful in terrestrial applications in which long life, reliability, and low contamination essential.
