Abstract
The present invention discloses a heat sink for enhancing heat dissipation efficiency of an electronic device. The heat sink includes a base for accommodating at least an electronic device, a dissipation plate overlaid on the base for absorbing and dissipating heat generated by the electronic device, and a fan for generating airflow. A side wall of the base is formed with at least an air duct for guiding the airflow generated by the fan through a bottom of the electronic device, thereby enhancing heat dissipation efficiency of the electronic device.
Claims2
A heat sink, comprising:
- a base having a hollow frame shape to be mounted on a circuit board, for an electronic device mounted therein, said base having a side wall formed with at least one air duct and another side wall formed with an air outlet;
- a dissipation plate overlaid on said base and formed with at least one air duct in communication with said air duct of said base;
- and
- a fan overlaid on said dissipation plate for blowing air toward a bottom of said electronic device through said air ducts of said dissipation plate and said base passing said air along a bottom surface of said electronic device and through said air outlet.
