Air conditioning tube, which is shaped into an air disperser blowing in the incoming air, by punching a plurality of small apertures (3, 5) in the tube (1) wall (2). For at least a part of the apertures (3, 5), the aperture direction deviates from the direction perpendicular to the tube axle. This axially inclined directing is caused by punching the above-mentioned apertures in such positions where the tube (1) wall has been designed to deviate from the axial direction. Alternatively, the apertures can be designed as inclined deflector or there can be arranged decompression chamber between the apertures and the tube interior. |
