Abstract
An axial fan is provided. The axial fan includes a base, a rotor, a guide and a plurality of blades. The guide connects to a guide tube to provide airflow. Each blade has a passive part and an active part, wherein the passive part is driven by the airflow from the guide to rotate the active part synchronously. The axial fan increases air quantity and decreases air pressure to provide efficient heat dissipation.
