220V Cooling Fan fan

Common "220V Cooling Fan" fan section curves, generally based on the wing section curves, then in accordance with design requirements, according to the angle of the blade root and the end portion of the rotary shaft, the roots and the ends of the width of the data, such as rotating stack form three-dimensional curved blades and curve fitting, and ultimately complete the "220V Cooling Fan" blade model design. Fan performance by many parameters, such as the stacking height, blade curvature, blade angle, blade pitch, blade thickness, number of blades, blade angle of attack, blade tip clearance, blade width, shaft diameter between the parameters, etc., and each other constraints, complex relationships. Constantly adjust the parameters, find the most suitable combination of objective job requirements, is carried out "220V Cooling Fan" fan design researchers are engaged in work.
