Abstract
A heat dissipation device includes a base (10), a tube (20), a fin member, a fan (50) and a heat pipe (60). The tube, the fin member and the heat pipe are all in contact with the base, for absorbing heat away from the base. The fin member and the fan are juxtaposed with each other along an axial direction of the tube. The fan blows air toward the fin member and enhances airflow within the heat dissipation device. The tube prevents the air from the fan from being dispersed, so that complete uniform airflow through the heat dissipation is maintained.
