Abstract
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.
