Abstract
A kinetically modulated fan structure is provided. The fan structure comprises a housing, a plurality of blades and an equilibrating structure, wherein the equilibrating structure is disposed on the inner side of the housing, and formed integrally with the housing and the blades. Thereby, the fan structure is adapted to be kinetically equilibrated during the manufacturing process. As a result, the modulation of the kinetic equilibrium with respect to the fan structure is eliminated since all of the yielded fan structures are uniform in quality. The simplified production is both time efficient and cost efficient, while producing a durable product.
