Patent ID: 7342794

Claim:
A heat sink configured to support an edge of a circuit card, said heat sink comprising: a thermally conductive base; a plurality of thermally conductive heat dissipating fins extending perpendicularly from said base, each fin having a length extending parallel to the base; two or more card supporting recesses, each card supporting recess at least partially defined by adjacent parallel faces of two adjacent fins extending perpendicularly from said base, the card supporting recesses defined in part by surfaces parallel to the base extending along the length of the fins, the card supporting recesses having a depth smaller than the height of said fins, and the adjacent parallel faces and the surface parallel to the base of each card supporting recess support the edge of a circuit card; at most three base recesses between adjacent card supporting recesses, each base recess at least partially defined by adjacent parallel faces of two adjacent fins extending perpendicularly from said base, the base recesses having a depth at least substantially equal to the height of said fins: and a face of the base disposed opposite said fins, said base being configured to be mounted with said face abutting a heat-generating component.
