Abstract
A heat dissipating module includes a heat dissipating assembly, a centrifugal fan, an airflow guiding hood and an auxiliary fan. The heat dissipating assembly includes a heat dissipating board and fins disposed thereon. Heat dissipating channels are formed between the fins. The centrifugal fan is disposed at a side of the heat dissipating channels. The airflow guiding hood covers the heat dissipating assembly and the centrifugal fan and is provided with a first airflow opening over the centrifugal fan, a second airflow opening over the fins and a third airflow opening at another side of the heat dissipating channels. The auxiliary fan is disposed between the fins and the second airflow opening.
