A stator and diffuser assembly (20) is introduced between an engine cooling fan (10) and engine (12). The stator acts (20) increase the static efficiency per unit airflow of the axial fan by reducing the rotational component of air traveling through the fan (10) and by directing the airflow in an axial direction towards the engine (12). The diffuser (20) acts to increase the static efficiency per unit airflow of the axial fan (10) used by decelerating the airflow, thereby providing more airflow to the engine (12) at a given fan rotational speed. The stator and diffuser assembly thus decreases the amount of horsepower necessary to drive the fan (10) at a given rotational speed and reduces noise. <IMAGE> |
