Fluid-flow-through cooling of circuit boards

摘要

A disclosed apparatus for use with a conduction-cooled card assembly may include a frame comprising first and second thermally conductive portions adapted to engage respective thermal management interfaces on opposite sides of a conduction cooling frame for at least one circuit card. The apparatus may also include a passageway extending between first and second openings in the frame so as to allow cooling fluid to flow into the first opening, through the passageway, and out of the second opening. According to a disclosed method, an insert may be installed between components of a mezzanine connector so as to increase a height of the connector. In some implementations, the installing of the insert may be performed while the first and second components of the mezzanine connector are mounted on a host card and a mezzanine card, respectively, so that installation of the insert between the first and second components increases a spacing between the host card and the mezzanine card.

主权项

1. An apparatus for use with a conduction-cooled card assembly, comprising:
an adaptor frame comprising first and second thermally conductive portions to engage respective thermal management interfaces on opposite sides of a conduction cooling frame for at least one circuit card; and a passageway extending between first and second openings in the adaptor frame so as to allow cooling fluid to flow into the first opening, through the passageway, and out of the second opening; wherein the adaptor frame is arranged to be removably installable between opposing interior walls of a chassis and is further arranged so that the first and second openings can mate with corresponding openings in first and second planar portions of the opposing interior walls of the chassis when the adaptor frame is installed in the chassis and the first and second planar portions of the opposing interior walls of the chassis are disposed in two different, parallel planes, the adaptor frame has a first end to engage the opposing interior walls of the chassis at a first location, and a second end to engage the opposing interior walls of the chassis at a second location that is closer to a motherboard of the chassis than the first location, and a width of the first end of the adaptor frame is greater than a width of the second end of the adaptor frame.
