AXIAL FLOW FAN CAPABLE OF MINIMIZING THE VOLUME OF BACKFLOW THROUGH A GAP BETWEEN A SHROUD AND THE AXIAL FLOW FAN

摘要

PURPOSE: An axial flow fan is provided to increase the cooling efficiency of a vehicle air conditioning system by maximizing the heat exchange efficiency of a heat exchanger.;CONSTITUTION: An axial flow fan comprises a hub(120) and a blade(110) which is arranged in a radial direction in the hub. The blade is coupled to the hub via a root(111). The portion of the blade close to the hub has an upward inclination and the tip(112) of the blade has a downward inclination.;COPYRIGHT KIPO 2012
