ABSTRACT:
A heat dissipation device for at least two heat-generating electronic components, includes a base for contacting with the heat-generating electronic components, a first fin set arranged on one part of the base, a second fin set arranged on another part of the base and at least a heat pipe sandwiched between the base and the first and second fin sets. The first fin set includes a plurality of fins defining a plurality of air passages therebetween. The second fin set includes a plurality of fins. Every two neighboring fins define therebetween an air passage communicating with a corresponding air passage of the first fin set. A channel which is parallel to and has 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.
