摘要：\\\"Fan axial flow, adapted the inflow, high efficiency\\\".The present inventionrelates to an axial flow fan which comprises a central hub efficiently, a plurality of blades,and a frame.And it is designed to operate in a shield of protection and induce flowthrough one or more heat exchangers in a set of automotive engine cooling, forexample.The blades of the fan have a radial distribution of the proportion of step thatprovides high efficiency and low noise in uniform flow field created by the heat exchanger(s) heat and shielding.Protection. The blade has no trawl, or dragged behind (that isopposite to the direction of rotation) in the region between the radial location R \\/ r =0.70 and the tip (R \\/ r = 1.00).The proportion of step of blade increases the radiallocation R \\/ r = 0.85 for a radial location between R \\/ r = 0.90 and R \\/ r = 0975, and thendecreases towards the tip of the blade.
