| description | The invention discloses an impeller, a machining method thereof and a high-temperature centrifugal fan applying the impeller. The impeller comprises a bottom plate, a face plate and a plurality of blades. A hub is arranged on the bottom plate. One side of the face plate is arranged to be an inner conical face, and the small end of the inner conical face is an air inlet. The blades are arranged in a circumferential array manner and extend in the radial direction. The lower ends of the blades are fixedly connected with the bottom plate, blade roots are fixedly connected with the hub, and the upper ends of the blades are arranged to be first bevel edges. The first bevel edges are fixedly connected with the inner conical face of the face plate, and radial intervals exist between the adjacent blades so that air channels can be formed. The blade roots of the blades communicate with the air inlet, and the thicknesses of the blades are gradually reduced in the direction from the blade roots to the blade edges. The ai |
