Heat dissipating device having a fin also functioning as a fan holder

A heat dissipating device comprising:

• a heat spreader for contacting with a heat-generating electronic device;
• a set of fins mounted on and thermally connecting with the heat spreader for dissipating heat from the heat spreader, said fins comprising a plurality of first fins each having a first body and a fastening fin positioned at a bottom of the fins and having a second body and a pair of tabs extending perpendicularly and downwardly from an edge of the second body of the fastening fin;
• a U-shaped heat pipe having a horizontal evaporating portion mounted on the heat spreader, and a pair of vertical parallel condensing portions extending from two opposite ends of the evaporating portion into the set of fins;
• a plurality of additional fins mounted on the evaporating portion of the heat pipe and sandwiched between the condensing portions of the heat pipe and below the set of fins, and the condensing portions of the heat pipe extending through the fins;
• and
• a fan mounted to a side of the fins;
• wherein the tabs of the fastening fin are oriented to the fan for engaging with the fan to mount the fan on the fins, and wherein the first body has a configuration similar to that of the second body;
• and
• wherein a first and a second opposite baffle walls extend perpendicularly from two lateral sides of the second body, respectively.
