Patent ID: 7637311

Claim:
A heat dissipation device for simultaneously dissipating heat generated by at least two heat-generating electronic components, comprising: a base adapted for contacting with the at least two heat-generating electronic components; a first fin set vertically arranged on one part of the base and comprising a plurality of fins, every two neighboring fins defining an air passage therebetween; a second fin set vertically arranged on another part of the base and comprising a plurality of fins, every two neighboring fins defining an air passage therebetween, which communicates with a corresponding air passage of the first fin set; at least a heat pipe sandwiched between the base and the first and second fin sets; wherein a channel being parallel to and having a width larger than that of the air passages of the first and second fin sets is defined in a middle of the second fin set; and a third fin set located at a lateral side of the base and proximal to the second fin set; wherein the third fin set is thermally connected to the first and second fin sets by the at least a heat pipe; and wherein the third fin set defines at least a receiving passage receiving a portion of the at least a heat pipe therein.
