Patent ID: 7715197

Claim:
A heatsink structure for the cooling of a closely packaged heat-producing device, said structure comprising: a folded arrangement having a pair of members forming spaced internal mutually facing parallel surfaces, said members being interconnected along one end to form an essentially inverted U-shaped configuration; each of said members possessing an external surface having a plurality of ridges in a waffle-configured lattice array formed therein, said plurality of ridges defining ridges extending in parallel with and ridges extending transversely of a flow of air passing over the external surface of each said member, enabling a boundary layer of air passing over each said external surface to be broken; and generating an enhanced flow of air increasing the cooling capacity of said heat sink structure; and wherein said heatsink structure is capable of having a component positioned in the space between said pair of members in communication with a heat-producing device for receiving heat generated by said heat-producing device and conveying the heat into said space and outwardly through said internal and external surfaces of said members.
