Abstract

The present invention provides an air flow guide ring for computer fan, which employs Bernoulli's principle to design a cross-section resembling an airfoil. The air flow guide ring can be applied to single or dual inlet centrifugal computer fan and axial-flow computer fan. As for the centrifugal computer fan, the air flow guide ring is combined with the blades of the cooling fan, and is placed under an inner edge ( inlet hole) of the fan cover; and, as for the axial-flow computer fan, it is disposed on a top end of the blades of the cooling fan, and the air flow guide ring is provided with a plurality of holes thereon. The air flow guide ring can not only provide the guidance of inhaled air flow, but also improve the stiffness of the fan blades and reduce the fluid leakage problem between the fan blades and the cover. As a whole, it can improve the stiffness and efficiency for the fan, and reduce the noise.
