ABSTRACT:
A non-conducting, plastic type of cryogenic fluid transfer conduit is presented which is suitable for transferring the cryogenic fluid from a standard reservoir into the midst of an electronics cabinet, such as a mini-computer, to cryogenically cool electronic components. When connected to a suitable enclosure, in which the electronic components to be cooled are mounted, the conduit transfers the cryogenic fluid from the reservoir to the enclosure with an acceptably low heat loss. The conduit subsequently transports the "warmed" cryogenic fluid, which picked up heat by cooling the electronic components, to the region of the reservoir where most or all of this "warmed" cryogenic fluid is vented either to the external environment, or back to the reservoir where it is subsequently cooled by a cryogenic refrigeration unit for re-use. A thermally insulating and moisture preventing outer covering allows the transition of the temperature from the cryogenic level to room temperature level to occur almost completely within the outer covering and, thereby, prevents the moisture condensation problems incurred if the surface temperature of the cryogenic conduit drops below the dew point of the operating environment.
