Abstract

A cooling fan is disclosed. The cooling fan comprises fan blades having a primary blade component and a secondary blade component. The primary blade component produces an axial airflow. The secondary blades produce a radial airflow. The axial airflow and the radial airflow, respectively created by the primary blades and the secondary blades, combine to provide an increase axial outflow. The primary and secondary blades combine the axial and radial flows respectively created by the blades to produce an increased outflow. The design has been observed to reduce tonal noise as well.
