A heat dissipating module includes a heat dissipating unit and a fan unit. The heat dissipating unit includes a plurality of heat dissipating fins sequentially stacked on top of one another. Each of the heat dissipating fins has a first end portion and a second end portion. The first end portion of each heat dissipating fin is divided into a first inclined airflow-guiding section and a second inclined airflow-guiding section, the first inclined airflow-guiding section of the first end portion of each heat dissipating fin is bent downward and slantwise, and the second inclined airflow-guiding section of the first end portion of each heat dissipating fin is bent upward and slantwise. The fan unit includes at least one fan adjacent to the heat dissipating unit for facing the first inclined airflow-guiding section and the second inclined airflow-guiding section of the first end portion of each heat dissipating fin.
