Patent ID: 7499280

Claim:
A heat dissipating device arranged to dissipate heat generated by a heat generating object mounted on a base, comprising: a heat sink body; a plurality of heat sink fins integral with the heat sink body; a heat-conducting area arranged to be pressed to a substantially flat surface of the heat generating object; a tip portion arranged approximately at a middle of the heat-conducting area and closest to the heat generating object among other areas of the heat-conducting area; an inclined surface of the heat-conducting area inclined outwardly from the tip portion such that a distance between the inclined surface and the heat generating object gradually increases in a state when the heat dissipating device is placed on the heat generating object; and a fastener including an attaching portion arranged to mount the heat dissipating device to the base, the attaching portion being arranged substantially radially outside of an outer peripheral portion of the heat generating object; wherein a distance between the attaching portion and the base is greater than a distance between the tip portion and the heat generating object in a state when the heat dissipating device is placed on the heat generating object such that when the heat dissipating device is mounted to the base, the base is bent.
