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

Abstract

The thermal aspects are discussed 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.<>
