Abstract
A heat dissipation device includes a thermal attach block (10), a heat pipe (30) thermally attached to the block, and a fin unit (90) thermally attached to the heat pipe. The block includes a curve-shaped bottom surface (124) allowing it to be thermally attached to a heat generating component (80) to absorb heat therefrom, and a top surface (122) opposite to the bottom surface. The heat pipe includes an evaporating section (32) at one end and a condensing section (34) at the other. The evaporating section can be thermally attached to the top surface of the block. The condensing section can be thermally attached to the fin unit.
Claims13
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.
A thermal attach block for thermally interconnecting a heat radiator to a heat generating device, the block comprising a basewall having a convex bottom surface for being thermally attached to the heat generating device, wherein a pair of sidewalls each are formed at one of two opposite sides of the basewall, each sidewall extends upwardly from one of the two opposite sides of the basewall, and a flange extends transversely and outwardly from each of the sidewalls, a clip engaging with the flange for locking the block to the heat generating device.
