Cryogenic fluid transfer conduit
First Claim
1. A cryogenic fluid transfer apparatus used for transferring a cryogenic fluid from a cryogenic reservoir to an enclosure for cooling an integrated circuit comprising:
- coupling means, having a venting passage therein, connected to the cryogenic reservoir;
a first conduit means connected to said coupling means at one end and to said enclosure at the other end for transferring the cryogenic fluid from said cryogenic reservoir in a first direction to said enclosure at a first temperature;
a second conduit means connected to said enclosure and said coupling means, and circumferentially located around said first conduit means for transferring the cryogenic fluid from said enclosure at a higher temperature in a direction opposite to said first direction;
said second conduit means communicating with said venting passage for venting said fluid at said higher temperature; and
insulating means connected to said coupling means and said enclosure around said second conduit means for preventing the condensation of moisture from the operating environment.

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.

13. A cryogenic fluid transfer apparatus used for transferring a cryogenic fluid from a cryogenic reservoir to an enclosure for cooling an integrated circuit and for returning the fluid to the cryogenic reservoir, comprising:
-
coupling means, having an internal venting passage therein, connected to the cryogenic reservoir; a first conduit means connected to said coupling means at one end and to said enclosure at the other end thereof for transferring the cryogenic fluid from said cryogenic reservoir in a first direction to said enclosure at a first temperature; a second conduit means connected to said enclosure and said coupling means, and circumferentially located around said first conduit means for transferring the cryogenic fluid from said enclosure at a higher temperature in a direction opposite to said first direction; said second conduit means communicating with said internal venting passage thereby venting said fluid at said higher temperature within said cryogenic reservoir; and insulating means sealably connected to said coupling means and said enclosure around said second conduit means for preventing the condensation of moisture from the operating environment. - View Dependent Claims (14, 15, 16, 17, 18, 19)
