Appl. No.:

12/021662

Inventors:

Richard M. Barina - Sebring FL, US
Derek I. Schmidt - Raleigh NC, US
James Scott Womble - Hillsborough NC, US

Assignee:

International Business Machines Corporation - Armonk NY

International Classification:

H01R 13/62

US Classification:

439157, 361755, 361798

Abstract:

A latch mechanism for securing a module in an electronic component chassis includes at least one lever arm attached to the module and rotable between a latched and unlatched position, at least a portion of the lever arm having an interference fit with the chassis when the lever arm is in the latched position. The latch mechanism further includes at least one pawl rotably attached to the module such that when the lever arm is moved to the latched position, the lever arm rotates the pawl into a latched position wherein the pawl has an interference fit with the chassis.

International Classification:

H05K 7/00

US Classification:

361747, 361727

Abstract:

A modular electronic system including a mechanism for releasably securing a modular device within a chassis, and for facilitating insertion and removal of the modular device. One embodiment provides a modular device that includes a handle secured to opposing pivotable lever arms. A follower pin secured to one end of the lever arms rides in a slot defined by the chassis. The slot is arranged so that pulling upward on the handle moves the follower pin in one direction along the slot to urge the modular device in a direction further into the device bay, and pushing downward on the handle urges the modular device in a direction out of the device bay, thereby providing a mechanical advantage to the user. When the modular device is fully inserted, retractable locking members provided on the modular device move into windows provided on the chassis, to releasably lock the modular device in the device bay. A module release mechanism includes a release plate that moves into engagement with a sloped or ramped surface of the locking members in response to squeezing the handle.

US Classification:

29764, 29741, 29758, 29762

Abstract:

A tool according to one embodiment includes an actuating mechanism including a cam plate; at least one gripper member operatively coupled to the cam plate; and a carriage for supporting the at least one gripper member, wherein the at least one gripper member is actuatable by the cam plate, wherein rotation of the cam plate causes the at least one gripper member to move between a first position and a second position, wherein when the at least one gripper member is in the first position, the tool is able to accept a processor for holding thereof, and wherein when the at least one gripper member is in the second position, the tool securely holds the processor therein. Additional systems and methods are also presented.

Abstract:

A liquid-cooled computer memory system includes first and second blocks in fluid communication with a chilled liquid source. A plurality of spaced-apart heat transfer pipes extend along a system board between memory module sockets from the first manifold block to the second manifold block. The heat transfer pipes may be liquid flow pipes circulating the chilled liquid between the memory module sockets. Alternatively, the heat transfer pipes may be closed heat pipes that conduct heat from the memory modules to the liquid-cooled blocks. A separate heat spreader is provided to thermally bridge each memory module to the adjacent heat transfer pipes.

Abstract:

A cooling system for a memory module comprises a heat conduction assembly for conducting heat from the memory module to liquid-cooled mounting blocks. In one embodiment, each heat conduction assembly includes a frame having opposing first and second supports, first and second heat spreader plates each extending from the first support to the second support, and a pair of flattened heat pipes each extending along a respective one of the heat spreader plates from the first support to the second support. The liquid-cooled mounting blocks releasably support the heat conduction assembly over a memory module socket with the memory module between the heat spreader plates.
