Abstract
Es wird ein Radiallüfter mit hoher spezifischer Leistung, insbesondere mit einem Trommelläufer (2) und einem Gehäuse (3), in dem ein sich erweiternder, als Druckraum wirkender Luftraum (4) sich spiralförmig zu einer Ausströmöffnung (5) erstreckt, und mit einer an den Seitenwänden des Gehäuses jeweils einen Kehlradius aufweisenden Gehäusezunge (6) zur Trennung von Druckraumanfang (4') und Druckraumende (4")vorgeschlagen, bei dem die Gehäusezunge (6) über zumindest einen Teil der Breite (B) des Gehäuses (3) mit einer durchgehenden Krümmung (7) ausgebildet ist. It becomes a radial fan with high specific power, in particular with a drum rotor (2) and a housing (3), in which an expanding air space (4), which acts as a pressure space, extends spirally to an outflow opening (5) and with one The side walls of the housing each have a throat radius housing tongue (6) for separating the pressure chamber beginning (4 ') and the pressure chamber end (4 "), in which the housing tongue (6) over at least part of the width (B) of the housing (3) a continuous curvature (7) is formed.
