Abstract
A centrifugal fan is provided. The centrifugal fan includes a housing, a driving device, and blades. The housing includes a circular base and at least two struts. Each of the struts physically connects the circular base and the remainder of the housing, and each of the struts includes two peripheral edges. The driving device is placed on the circular base. Each of the blades has an arc shape and the blades are located in the housing. The driving device rotates the blades. The two peripheral edges of each of the struts form orthogonal curves with the blades.
