Abstract

Es wird ein spezieller Radialventilator mit einer trichterförmigen Lufteinlaufdüse (1) für einen axialen Primärluftstrom (P) und mit einem daraus einen radialen Luftstrom -(R) erzeugenden Laufrad (2) vorgeschlagen. Die Wandung (3) der Lufteinlaufdüse (1) weist einen kegelstumpfmantelförmigen Einströmabschnitt (3a) und einen sich in axialer Richtung (X-X) an diesen anschließenden, zylindermantelförmigen, koaxial zu einer zentrischen Ansaugöffnung (4) des Laufrades (2) angeordneten Ausblasabschnitt (3b) auf. Zwischen dem Laufrad (2) und der Wandung (3) der Lufteinlaufdüse (1) befindet ein Spalt (5) zum Einlaß eines Sekundärluftstromes (S). Zur Reduzierung der Geräuschentwicklung weist die Wandung (3) der Lufteinlaßdüse (1) weist Umfang mindestens ein Störungselement (6a, 6b) auf, durch das in der Lufteinlaßdüse (1) eine an ihrer Wandung befindliche Grenzschicht des Primärluftstromes (P) infolge einer Luftdurchmischung verbreitert wird.
