ABSTRACT:
A fan having a plurality of blades where a selected number of the blades are arranged with their leading faces disposed parallel to the axis of rotation of the fan. The remaining blades are arranged with their leading faces at angles to the axis of rotation such that the air streams from the two types of blades intersect to create turbulent flow. The fan's heat transfer ability is increased and the air flow from the fan is dispersed over a wider area than with conventional fans.
