Abstract (en)
[origin: WO2007089081A1] The present invention relates to an axial flow fan, and an object thereof is to make it capable of promoting structural stability so as to decrease deformation and unbalance of a blade as well as accomplishing low noise level by determining a distribution angle of the blade with an optimum clearance angle and thereby determining uneven rate of the blade.
