220V Cooling Fan fan with stress

Common "220V Cooling Fan" fan section curve, generally based (Russia renowned  contemporary aviation science pioneers, raised function, laid the wing aerodynamic calculation of the theoretical basis) wing section curve design, and then follow the design needs, according to the angle of the blade root and ends with the rotation axis of the roots and the ends of the width of the data such as rotation stacked to form a three-dimensional "220V Cooling Fan" curved blades and curve fitting, and ultimately complete the fan model design. Fan performance subject to a number of parameters, such as laminated height, blade curvature, inclination blade, blade pitch, blade thickness, number of blades, blade angle of attack, blade tip clearance, blade width, spindle diameter, etc., and among the parameters mutual constraints, complex relationship. Constantly adjust the "220V Cooling Fan" parameter, find the most suitable combination of objective job requirements, fan design is carried out by researchers working on.
