US Patent:

58969225, Apr 27, 1999

Filed:

Apr 15, 1998

Appl. No.:

9/060847

Inventors:

Gregory M. Chrysler - Chandler AZ
Richard C. Chu - Poughkeepsie NY
Gary F. Goth - Pleasant Valley NY
Robert E. Simons - Poughkeepsie NY

Assignee:

International Business Machines Corporation - Armonk NY

International Classification:

F28F 312

US Classification:

165165

Abstract:

A cold plate includes two flow-wise isolated coolant (or refrigerant) passages (or sets of passages) for use in conjunction with separate refrigeration systems. The cold plate passages do not permit flow communication between distinct coolant (or refrigerant) paths. This permits two distinct cooling systems to operate in a redundant manner. Nonetheless, flow isolation is achieved while still maintaining tight thermal coupling between each path and the object, such as an electronic computer processor module, to be cooled.

Assignee:

International Business Machines Corporation - Armonk NY

International Classification:

H05K 720

US Classification:

361699

Abstract:

A redundant refrigeration system is used in conjunction with a dual passage cold plate to provide reliable cooling for electronic circuit modules particularly to such modules which incorporate computer processors for which long term "up time" is very highly desirable. Separate compressor-expansion device-condenser refrigeration systems are coupled to a single cold plate which maintains flow-wise isolation between refrigerant streams while at the same time providing close thermal coupling.

Assignee:

International Business Machines Corporation - Armonk NY

International Classification:

H05K 720

US Classification:

361695

Abstract:

A cabinet with air inlet and exhaust openings includes one or more air-moving devices for the air cooling of circuit cards contained within the cabinet. The circuit cards are insertable into a board (back plane) which also contains an electronic circuit module which is cooled by at least one refrigeration system which may also be disposed within a portion of the cabinet. In one embodiment, a portion of the exhaust air stream is used to also cool a condenser portion of the refrigeration system. The refrigeration system is preferably a dual/redundant system with two distinct coolant loops passing through a single cold plate in contact with the circuit module.
