A composite heat dissipation fan, including an impeller having first blades, and the first blades having a periphery combined with second blades for creating a side directed wind supply. The impeller is provided with a magnet ring which is energized with the stator coils of the base plate, so that the impeller is induced to rotate about the rotation shaft of the base plate. The first blades draw the ambient cold air through the wind inlet opening, and the wind outlet opening of the base plate drains the wind outward. The second blades uses part of the cold air to drain wind sideward, thereby providing a multi-directional wind draining effect so as to increase the heat dissipation efficiency.
