Abstract:
1. A heat conduction apparatus, comprising: a heat sink having a base, a plurality of fins and an end plate; a fluid transfer cooling member extending through the base, the fins and the end plate; and a surface of the end plate including a coupling member operable to releasably and interchangeably couple one of a selected blank member and a cold plate to the end plate in response to a cooling requirement of the heat sink, wherein the blank member includes a plastic material; the cold plate including a first single surface in contact with the surface of the end plate, and also including a third single surface opposing the first single surface, and including a fluid conduit within the cold plate; upon interchange of the cold plate and the blank member, the blank member including a second single surface in contact with the surface of the end plate in replacement of the cold plate, the blank member also including a fourth single surface opposing the second single surface and being free of any fluid conduit therein or any means of moving a cooling fluid therethrough and the cold plate including conduit means for moving a cooling fluid therethrough; and each of the cold plate and the blank member including a coupling member aperture aligned with the coupling member of the end plate and extending from the third and fourth single surfaces respectively of the cold plate and the blank member to accommodate a fastening member for attaching one of the cold plate and the blank member to the end plate.
