Abstract
The invention relates to an inlet nozzle for a radial fan, having a plurality of flow sections defined over the wall of the inlet nozzle (1), as viewed in the direction of flow, said flow sections comprising at least: an inlet section (2) which has an inlet opening (7), a perturbation section (3) directly adjoining the inlet section (2), and an outlet section directly adjoining the perturbation section (3), wherein the flow cross-section of the inlet nozzle (1) decreases in the inlet section (2), and wherein the perturbation section (3) that is formed between the inlet section (2) and the outlet section (4) is designed as cylindrical over its entire axial length and extends parallel to the rotational axis of the inlet nozzle (1), so that the flow cross-section of the inlet nozzle (1) is constant in the perturbation section (3).
