ABSTRACT:
A chassis is provided having a heat conductive side wall together with a flat heat conductive tab member extending therefrom, together with a planar heat sink for supporting a heat generating electrical device, the heat sink having a pair of flat, parallel, resilient prongs and including first and second flat inner surfaces facing each other and separated from each other by a distance slightly greater than the thickness of the tab to form a clearance gap, together with a pair of wedge clamps for squeezing said prongs together to produce a good thermal contact between the prongs and the tab member. A narrow slot is formed within the heat sink for enhancing the resiliency of the prongs to enable easy actuation of the clamps.
