Patent ID: 6898084

Claim:
An apparatus for operably conveying heat away from a heat source, said apparatus comprising: (a) a thermally conductive substrate having first and second opposed sides and a thickness defined between said first and second opposed sides, the thickness of said substrate forming a planar boundary thereof; and (b) an insert portion disposed in said substrate and being positioned so as not to extend beyond said planar boundary, said insert portion having a thermal conductivity value of at least 1.5 times that of said substrate along at least two axial directions, with one of such axial directions extending substantially perpendicularly to said first and second opposed sides, said substrate being operably disposed adjacent to the heat source such that at least a portion of said insert portion is in immediate thermal contact with such heat source, said insert portion including one or more arms extending radially outwardly from a first location in said substrate that is immediately adjacent to, and in thermal contact with, the heat source, said one or more radial arms extending within said planar boundary.
