Abstract
A heat dissipation device includes a cooling fan () defining an air inlet and an air outlet () oriented perpendicular to the air inlet; a metal foam () is arranged in the air outlet of the cooling fan, and a heat pipe () has a condensing end () being thermally attached to the metal foam. The metal foam forms numerous open cells (). A plurality of guiding holes () are defined in the metal foam facing to a rotor () of the cooling fan for an airflow generated by the cooling fan to flow therethrough. The guiding hole () has a size larger that that of the open cell (). The guiding hole has an outer end opened to an outside of the cooling fan ().
