The invention relates to a radiating air channel, which comprises a fan. The radiating air channel further comprises a collecting area, an amplifying area and an output area which are communicated with each other in turn, wherein the collecting area is arranged in a cabinet; a communicated area is formed by the three layers of the air channel; the most part of the fan is located in the communicated area; and the area of a cross section of the amplifying area which is vertical to the axial direction of the fan is bigger than the area of the cross-section of the collecting area. The most part of the fan is located in the communicated area which is formed by the collecting area, the amplifying area and the output area, thereby wholly reducing the volume of the cabinet and being beneficial to mounting and maintaining. A three-layer air channel design is adopted, the length of the air channel of the collecting area with a smaller cross section is reduced, and the area of the cross-section of the amplifying area wh
