Design of a candidate thermal control system for a cryogenically cooled computer

Addresses the thermal aspects of an immersion-cooled computer designed to operate at cryogenic temperatures. Several of the major thermal design issues are discussed in detail. These include: (1) the selection of a working fluid, (2) the determination of the mode, or modes, of heat transfer to be used, (3) the selection, or development, of any required heat-transfer correlations, and (4) the selection of a refrigeration system. The results of a preliminary analysis of a candidate thermal control system are also presented.<>
