Abstract:
A heatsink for absorbing heat generated from a heat-generating source, the heatsink being in contact with the heat-generating source, and dissipating the absorbed heat into the air, the heatsink comprising:a plurality of sheet-shaped heatsink plates each having a heat-absorbing portion in contact with an upper surface of the heat-generating source and substantially normal thereto to absorb heat from the heat-generating source, and a heat-dissipating portion extending from the heat-absorbing portion to dissipate the absorbed heat into the air, wherein the plurality of heatsink plates are arranged in a stack, to form a heatsink plates stack and the heat-absorbing portions form a center of the heatsink plates stack; and a pair of compression blocks positioned to interpose the heat-absorbing portions of the heatsink plates stack therebetween and compress the heat-absorbing portions; and wherein each of the heatsink plates has at least one folded portion that allows the heat-dissipating portion of the individual heatsink plates to radially spread out by a force exerted upon the folded portion when the heatsink plates are tightly joined together by the pair of compression blocks, to give the heatsink an elliptical column form.
