One embodiment provides an air baffle assembly for controlling airflow through a cable opening in a rack. The rack is configured for removably supporting a plurality of modular electronic components. The cable opening on the rack receives a plurality of cables connected to the modular electronic components. The air baffle assembly includes a track secured to the rack adjacent to the cable opening and an air baffle movably supported on the track over the cable opening. The track includes a rail guideway. The air baffle includes at least a flexible first rail movably received by the first rail guideway. The first rail flares laterally along a range of engagement of the first rail with the first rail guideway, to bias the air baffle in one longitudinal direction.

One embodiment of the invention provides a rack assembly for cooling a computer system. A rack provides support for one or more columns of heat-generating electronic devices. Device fans move air from an air inlet side of the rack through the devices and through an air outlet side of the rack. A unitary door has a support frame spanning the air outlet side of the rack and hingedly coupling the door to a rear vertical edge of the rack. The unitary door includes an air-to-liquid heat exchanger panel spanning an air outlet passage inside the support frame so that substantially all of the air passing through the air outlet side of the rack must pass through the heat exchanger panel. The air outlet passage has a cross-sectional area that is substantially equal to or greater than the cross-sectional area of the one or more columns of heat-generating devices. A coolant circulation system includes a coolant distribution unit for chilling liquid coolant, a supply hose placing the coolant distribution unit in fluid communication with an inlet manifold of the air-to-liquid heat exchanger, and a return hose placing an outlet manifold of the air-to-liquid heat exchanger in fluid communication with the coolant distribution unit. The supply hose and return hose are routed outside the cross-sectional area of the air outlet passage.

A load frame has an open region exposing a surface of an electronic component. A heat sink is disposed on the load frame and has a surface in thermal contact with the surface of the electronic component. A non-influencing fastener is disposed within a bore in the heat sink and threaded into the load frame for securing the heat sink to the load frame. The non-influencing fastener includes a screw with a head; a tapered ring disposed below the head of the screw and having a tapered lower peripheral surface; a sealing ring engaging the tapered lower peripheral surface of the tapered ring; and a load washer disposed between the sealing ring and the load frame. Compression of the rings by turning of the screw into the load frame causes the sealing ring to expand against the bore of the heatsink. Preferably, the sealing ring has a curved outer surface.
摘要:
In a system for liquid cooling of electronics, where the electronics are subject to rotation in space, a liquid coolant storage tank includes a degassing and vortex-preventing structure to allow bubbles to float to the surface of the liquid inside the tank, and also to prevent vortices from forming near the outlet from the tank. The structure includes nested tubes or conduits. An inner conduit extends from the inlet into the tank, and its open end is covered by a second conduit with a baffle across its end, so that the flow is directed by the baffle to flow back along the outside of the inner conduit, and inside of the outer conduit. Especially at the inlet, a third conduit with large perforations surrounds the open end of the outer conduit. Smaller perforations on the inner conduit at the outlet side discourage any vortex from forming there. Reversal of the liquid flow, and the gradual increase in flow cross section prevent surging inside the tank.

A rack for supporting electronic devices and modules with adjustable rails. The rack has a vertical wall with a set of holes at various elevations, each set of holes including at least a proximal hole evenly spaced apart from a distal hole. A longitudinally-extending rail has a set of clips for selectively securing the rail to the vertical wall, wherein the set of clips includes at least a proximal clip selectively receivable in the proximal hole at a selected elevation for supporting a proximal end of the rail and a distal clip selectively receivable in the distal hole at the selected elevation for supporting a distal end of the rail. The system may include a second rail for securing to an opposing vertical wall of the rack to form a shelf or bay for an electronic device. Each rail may be latched in place and can be selectively installed and removed without use of tools.

Rack assemblies and methods for cooling one or more rack-based computer systems, as well as data center configurations that utilize the rack assembly. The rack assembly comprises a rack providing support for multiple columns of heat-generating electronic devices and device fans for moving air from an air inlet side of the rack through the devices and through an air outlet side of the rack. The rack assembly also comprises a unitary door having a support frame spanning the air outlet side of the rack and hingedly coupling the door to a rear vertical edge of the rack. The door includes an air-to-liquid heat exchanger panel spanning an air outlet passage inside the support frame so that substantially all of the air passing through the air outlet must pass through the heat exchanger panel. The air outlet passage has a cross-sectional area that is substantially equal to or greater than the cross-sectional area of the multiple columns of heat-generating devices.

摘要:
A heat transfer apparatus comprises a load frame having load springs and an open region that exposes an electronic component. The load frame is mounted to a printed circuit board on which the electronic component is mounted. A heat sink assembly is disposed on the load frame and has a main body in thermal contact with the electronic component through a thermally conductive material. The heat sink assembly has load arms for engaging the load springs. A load plate extends between the load arms and has an actuation element operative to displace the main body relative to the load plate and thereby resiliently deform the load springs and produce a load force that compresses the thermally conductive material to achieve a desired thermal interface gap between the main body and the electronic component. Non-influencing fasteners secure the heat sink to the load frame and maintain the desired thermal interface gap.
