Abstract:
An electromagnetic shielding heatsink with venting capabilities, comprising:a heatsink block comprising a base plate comprising thermally and electrically conductive material, and an extended surface having at least one aperture therethrough, wherein the extended surface extends beyond a wall thickness of the baseplate, the aperture allowing a thermal carrier to pass from a first side of the heatsink block to a second side of the heatsink block, wherein the aperture is sized to prevent an electromagnetic frequency lower than a cutoff frequency of the aperture from passing through the aperture and the extended surface is sized to provide adequate heat transfer; at least one heat dissipating source; at least one thermal plate thermally coupled to said heat dissipating source; and at least one thermal coupler comprising a thermally conductive material, for coupling said heatsink block to said thermal plate.
