Abstract:
A heat sink to dissipate heat that is generated by a source, said heat sink comprising a core including a plurality of heat conducting fins to collect the heat generated by the source, each fin of said plurality of heat conducting fins having a front face, a back face spaced rearwardly from said front face, an air exhaust cavity located between said front and back faces, an inner air blade removed from said front face and bent rearwardly from said front face towards said back face so as to lie within said air exhaust cavity, a top connected between said front and back faces, and an air intake opening formed through said top to receive a supply of fan air therethrough, a portion of the fan air received through said air intake opening being diverted from said air exhaust cavity by said inner air blade, said air exhaust cavity extending between said air intake opening and the atmosphere so that the heat generated by the source and collected by said fin is blown into the atmosphere by the supply of fan air which is not being diverted from said air exhaust cavity by said inner air blade.
