Air-guide pipe and radiating device using same

The invention discloses an air-guide pipe and a radiating device using the same. The air-guide pipe comprises a pipeline and a pipe wall made of soft plastics, wherein the pipeline and the pipe wall form an air inlet and an air outlet. The air-guide pipe is characterized in that the pipe wall is provided with a radiating fin mounting hole for mounting a radiating fin; the area of the radiating fin mounting hole is 0.75 to 0.9 times of that of a first base of the radiating fin; and the area of the ventilating side of the pipeline is 0.75 to 0.9 times of that of the ventilating side of the radiating fin. In the invention, the pipe wall is made of the soft plastics, the pipe wall is provided with the radiating fin mounting hole, the radiating fin is mounted in the pipeline, the connection ismore compact, and the space is saved.
