Patent ID: 7757751

Claim:
A heat dissipation device comprising: a base comprising a base plate having a bottom surface adapted for contacting with a heat-generating electronic component and a substrate; a fin set comprising a plurality of horizontally stacked fins parallel with and spaced from each other, the fin set defining two cutouts in lower portions of middles of two opposites sides thereof; at least one heat pipe thermally connecting the base and the fin set together; and two clamping pads attached to two opposite edges of the substrate, each of the clamping pads having a tab extending toward the fin set from a lateral edge of each of the clamping pads, the tab of each of the clamping pads being received in a corresponding cutout of the fin set and abutting a lateral side of the fin set in the corresponding cutout, thereby reinforcing the intensity of the fin set; wherein the base plate is made of a material that has higher heat conductivity than that of the substrate, and the at least one heat pipe has an evaporating section sandwiched between the base plate and the substrate.
