Compact and serviceable packaging of a self-contained cryocooler system

Claim 2

A self-contained, portable cryogenic cooling system for an Electronic Industry Association (EIA) enclosure generating a nominal 250 watts of heat lifting capacity, capable of maintaining a constant low temperature of 77° K. and fitting within a 24.5 in.×17.5 in.×29.5 in. space in an EIA enclosure wherein said cooling system includes: an integral Stirling cryocooler having a compressor section and an expander/regenerator section including a cold head; and heat rejection means for rejecting heat generated by said cryocooler including fan means for passing air over said cryocooler where said air is heated, and then through a heat exchanger and away from said cooling system.

Claim 3

The cooling system of claim 1 wherein said heat exchanger is located in a closed fluid loop which also includes a pump, a pump motor, a rejector and fluid connection means.

Claim 4

The cooling system of claim 1 further including electronic control means for variable speed operation of said fan, pump and cryocooler motors as well as prognostic capabilities for maintaining proper operation/reliability and communication means to alert a host computer system of non-standard operating conditions.

Claim 5

A cooling system for an Electronic Industry Association (EIA) enclosure for removing heat from heat generating components within the EIA enclosure comprising: an integral Stirling cryocooler; a generally rectangular base frame member sized to fit into the EIA enclosure for supporting said integral Stirling cryocooler thereon, whereby a cold head of said integral Stirling cryocooler is operatively connected to the heat generating components within the EIA enclosure to remove heat therefrom; support means for flexibly connecting said integral Stirling cryocooler to said base frame member; slide means member for movably supporting the cooling system during selective movement between an operating position inside of the EIA enclosure and a non-operating position outside the EIA enclosure; and external means connected to the cooling system when in the operating position consisting essentially of electrical power means.

Claim 6

A cooling system for an Electronic Industry Association (EIA) enclosure for removing heat from heat generating components within the EIA enclosure comprising: an integral Stirling cryocooler; a generally rectangular base frame member sized to fit into the EIA enclosure for supporting said integral Stirling cryocooler thereon, whereby a cold head of said integral Stirling cryocooler is operatively connected to the heat generating components within the EIA enclosure to remove heat therefrom; support means for flexibly connecting said integral Stirling cryocooler to said base frame member; slide means member for movably supporting the cooling system during selective movement between an operating position inside of the EIA enclosure and a non-operating position outside the EIA enclosure; and external means connected to the cooling system when in the operating position consisting essentially of electrical power means.

Claim 7

A cooling system as set forth in claim 4 wherein said support means includes spring means wherein said spring means enables less than 0.02 g vibration to be transmitted to the heat generating components.

Claim 8

A cooling system as set forth in claim 5 wherein said slide means contacts a lower portion of the EIA enclosure.

Claim 9

A cooling system as set forth in claim 4 further including: heat rejection means for rejecting heat generated by said cryocooler including fan means for passing air over said cryocooler where said air is heated, and then through a heat exchanger and away from said cooling system.

Claim 10

The cooling system of claim 7 wherein said heat exchanger is located in a closed fluid loop which also includes a pump, a pump motor, a rejector and fluid connection means.

Claim 11

The cooling system of claim 8 further including electronic control means for variable speed operation of said fan, pump and cryocooler motors as well as prognostic capabilities for maintaining proper operation/reliability and communication means to alert a host computer system of non-standard operating conditions.
