Abstract

A passive fan assembly includes an impeller and a plurality of guiding blades set up in front of the impeller. The guiding blades and rotor blades of the impeller are positioned in a nearly perpendicular relationship from the cross-sectional view. Accordingly, airflow entering the passive fan assembly is guided along the curve surface of the guiding blades to effectively blow the rotor blades of the impeller.
