Abstract
A cooling fan comprises a rotor configured to generate airflow. The cooling fan further comprises an outlet guide vane adapted to receive the airflow generated by the rotor and to orient the airflow in a substantially axial direction relative to the rotor. The cooling fan further comprises a diffuser configured to receive the airflow from the outlet guide vane and produce airflow with higher static pressure relative to an inlet of the diffuser. The cooling fan produces a work coefficient greater than 1.6 and a flow coefficient greater than or equal to 0.4.
