Abstract

A heat dissipation device is to be mounted in a computer enclosure for dissipating heat generated by a VGA card (10). The heat dissipation device includes a heat sink (90), a fan (60) and a fan duct (50) connecting the heat sink (90) and the fan (60). The heat sink (90) contacts a heat-generating device (12) of the VGA card. The fan (60) has an inlet port (62) and an outlet port (63). The outlet port (63) communicates with an ambient air outside the computer enclosure. The fan duct (50) has two open ends (55,52). One open end (55) engages with the heat sink (90) and the other open end (52) engages with the inlet port (62) of the fan (60).
