Abstract
(EN)
The objective of the present invention is to provide a heatsink that can exhibit an excellent cooling property even for a heat producing element arranged in a narrowed space and having a high heat value. A heatsink comprising: a plurality of heat pipes that are thermally connected to a heat producing element; and a heat dissipating part that is thermally connected to the plurality of heat pipes, wherein evaporation parts of the plurality of heat pipes which are thermally connected at least to the heat producing element have prolate portions the cross section shape of which in the direction orthogonal to the heat conveyance direction of the plurality of heat pipes is prolate and wherein the surfaces, in the thickness direction, of the prolate portions are opposed to the heat producing element.
