Patent ID: 8322404

Claim:
A heat dissipation device adapted for removing heat from an electronic device and at least two electronic components, comprising: a rectangular base plate having a bottom adapted for contacting with the electronic device; a first fin set comprising a plurality of first fins perpendicularly arranged on the base plate; a second fin set comprising a plurality of second fins attached to a lateral side of the first fin set and perpendicular to both the first fins and the base plate; a fan mounted on the first fin set and the second fin set, wherein the fan covers tops of the first fin set and the second fin set and an airflow generated by the fan flows to three lateral sides of the heat dissipation device through the first fin set and the second fin set, adapted to cool the at least two electronic components located near orthogonally neighboring sides of the base plate; and two first heat pipes thermally connecting the base plate and the first fin set and a second heat pipe thermally connecting the base plate and the second fin set; wherein the second heat pipe comprises an evaporating portion sandwiched between a bottom of the first fin set and the base plate, a condensing portion extending through the second fin set and a connecting portion interconnecting the evaporating portion and the condensing portion of the second heat pipe; wherein the connecting portion of the second heat pipe comprises a linear portion sandwiched between a bottom of the second fin set and the base and an arched portion located at the lateral side of the first fin set; and wherein the base plate defines a recession in a corner of the top surface thereof, the second fin set defines a cutoff in a corner of the bottom thereof, and the recession and the cutoff cooperatively define a receiving space accommodating the linear portion of the connecting portion of the second heat pipe.
