Abstract
A removable gasket for sealing an air-cooled hollow core module to the port of a chassis plenum for supplying cooling air includes an aluminum frame to which a thermally conductive elastomer seal is vulcanized. The gasket frame provides support for the seal and serves as a compression limiting stop for the seal. The gasket is held in alignment with the cooling channel of the hollow core module with attachment screws, greatly facilitating the gasket removal and repair of the module, and realignment with the chassis plenum port upon reassembly.
Claims20
A gasket assembly for constraining air flow through the core of a hollow core electronics module, said gasket assembly comprising:
- a frame having two opposite surfaces, said frame having first and second apertures therethrough between said two surfaces, said frame adapted for mounting one of said surfaces against the electronics module such that said apertures are in communication with the core;
- and
- a seal having first and second openings, said seal extending through said first and second apertures and affixed to said two surfaces.
An electronics module comprising:
- support means having first and second side walls in substantially parallel relationship, said side walls being spaced apart by a gap;
- first and second circuit boards affixed respectively to said first and second side walls;
- a gasket assembly for constraining air flow through said gap, said gasket assembly comprising a frame having two opposite surfaces, said frame having an aperture therethrough between said two surfaces, said frame having one of said surfaces mounted against said support means such that said aperture is in communication with said gap, and a seal having an opening, said seal extending through said aperture and affixed to said two surfaces;
- and
- means for fastening said gasket assembly to said support means.
A gasket assembly for constraining air flow through the core of a hollow core electronics module, said gasket assembly comprising:
- a frame having two opposite surfaces, said frame having an aperture therethrough between said two surfaces, said frame adapted for mounting one of said surfaces against the electronics module such that said aperture is in communication with the core;
- and
- a seal having an opening, said seal extending through said aperture and affixed to said two surfaces,
- wherein said one surface of said frame adapted for mounting against the module includes a raised surface elevated above said one surface, said seal affixed to said one surface being more elevated above said one surface than said raised surface.
