ABSTRACT:
A heat dissipation device for cooling an electronic device mounted on a printed circuited board includes a heat sink thermally contacting the electronic device, a fan defining a plurality of through holes in a periphery thereof and a fixing device fixing the fan on a side of the heat sink. A plurality of fasteners are attached on a bottom of the heat sink and fasten the heat sink on the printed circuited board. The fasteners block the through holes in a bottom of the fan. The fixing device includes fixing brackets attached to the heat sink and a plurality of resilient connecting devices. Each resilient connecting device has an end extending through a corresponding through hole in the bottom of the fan and connected to the fan, and another end connected to a bottom of a corresponding fixing bracket.
