Patent ID: 7606036

Claim:
A heat dissipation device comprising: a thermal attach block having a convex bottom surface for being thermally attached to a heat generating component to absorb heat therefrom, and a top surface opposite to the bottom surface; a heat pipe having an evaporating section being thermally attached to the top surface of the block, and a condensing section extending outwardly from the evaporating section; and a fin unit being thermally attached to the condensing section of the heat pipe; wherein the thermal attach block comprises a basewall forming the bottom surface at a bottom side thereof, and a pair of sidewalls each formed at one of two opposite sides of the basewall; wherein the basewall and the sidewalls cooperatively define a space for receiving the evaporating section of the heat pipe therein; and wherein the sidewalls extend upwardly and outwardly from the basewall, and a distance between the sidewalls gradually increases along the extending direction of the sidewalls.
