An exemplary heat dissipation device includes a base, spaced fins, a bracket, a shaft and a first impeller. The base directly contacts a heat-generating source. The fins are mounted on the base to dissipate heat transferred from the base by nature convection and thermal radiation. The bracket is mounted on the fins and includes a rotor. The shaft is engaged with the rotor and is located above of the fins. The first impeller is located at above of the bracket and engaged with a top end of the shaft. Heat generated by the heat-generating source is absorbed by the base and then is transferred to the fins for dissipation. Air around the fins and the base is heated and moves upwards to drive the first impeller to rotate.
