A heat dissipation module includes a heat sink, a wind-guiding element and a pivot. The wind-guiding element is disposed on the heat sink, and the pivot is connected between the heat sink and the wind-guiding element to allow the wind-guiding element to rotate relative to the heat sink via the pivot. The wind-guiding element can change a direction of airflow to provide an optimal heat dissipation effect. Additionally, an electronic device using the heat dissipation module is also provided. The heat dissipation module can provide superior heat dissipation effect to an electronic component on the electronic device and maintain a normal operation of the electronic component.
