Patent ID: 7072181

Claim:
A heat dissipating device which dissipates heat from a heat generating object, comprising: a heat receiving unit having a heat receiving surface and a heat dissipating surface on an opposite side of the heat receiving surface, the heat receiving surface being thermally coupled to the heat generating object; a heat transferring unit, mounted on the heat dissipating surface of the heat receiving unit, which transfers the heat received by the heat receiving surface and diffuses the transferred heat over the heat dissipating surface; a heat dissipating unit, mounted on the heat dissipating surface of the heat receiving unit, which dissipates the diffused heat; and a heat conductive cover, arranged between the heat transferring unit and the heat dissipating unit, that covers the heat transferring unit, wherein the heat transferring unit includes a plurality of heat pipes each of which has a long shape and extends in the same direction as to each other along the heat dissipating surface of the heat receiving unit, wherein the heat conductive cover is configured as a plate, and includes a portion, which contacts the heat dissipating surface of the heat receiving unit, and a plurality of projecting portions, each of which projects from the heat dissipating surface, receives each of the heat pipes of the heat transferring unit, and has an inner surface being thermally connected to the outer surface of each heat pipe received therein, and wherein the heat dissipating unit includes a plurality of heat dissipating plates which are formed independently to each other and arranged in the extending direction of each heat pipe to separate from each other, each heat dissipating plate extending in a direction which crosses the extending direction of each heat pipe and having a plurality of recesses which fit on the projecting portions of the heat conductive cover and are thermally connected thereto.
