ABSTRACT:
A cooling fan assembly includes a cooling fan (1) having a rotary hub (14) and a plurality of fan blades extending radially from an outer periphery of the hub, a hood (20) connected with the cooling fan, and a guiding member (40) located in a center of the hood. The hood forms an air inlet (22) near the cooling fan and an air outlet (24) far from the cooling fan. The guiding member is located close to hub of the cooling fan and so configured that a low pressure area is prevented from being formed in the hood near the hub, wherein the guiding member guides an airflow generated by the cooling fan to flow from the air inlet toward the air outlet.
