Abstract
A centrifugal fan module, a heat dissipation device having the same and an electric device having the heat dissipation device are provided, in which the heat dissipation device includes a fin module and a centrifugal fan module including a volute-shaped frame and a centrifugal fan pivoted in the volute-shaped frame. The volute-shaped frame includes an air inlet, a larger air outlet and a smaller air outlet. The air inlet and the smaller air outlet are both on the same surface of the volute-shaped frame. The larger air outlet is coupled to the fin module. The smaller air outlet is arranged correspondingly to a maximum wind-speed flowing path of the centrifugal fan.
