Abstract

Es wird ein Radialgebläse mit einem topfartigen Laufrad (10) vorgeschlagen, das an seinem Umfang mit einem Schaufelkranz (15) versehen ist. Ein das Laufrad (10) aufnehmendes Gehäuse (11, 11') erweitert sich ausgehend von einem teilkreisartig gekrümmten, direkt entlang des Schaufelkranzes (15) verlaufenden Umfangswandbereich (19) schneckenartig in Drehrichtung des Laufrads (10) radial zu einem Auslaß (21) und besitzt zwei die axialen Stirnseiten des Laufrads (10) abdeckende Seitenwandungen (23, 24). Eine an einer der Seitenwandungen (24) angeordnete Trennwand (26) greift in das topfartige Laufrad (10) ein und unterteilt dessen Innenraum in einen ersten und einen zweiten Saugraum. Dem ersten Saugraum ist eine Ansaugöffnung (28) zugeordnet, und der zweite Saugraum ist dem direkt entlang des Schaufelkranzes (15) verlaufenden Umfangswandbereich (19) zugewandt. Dabei sind Mittel zur Strömungsabdichtung der Spalte zwischen den Rändern der Trennwand (26) und dem Laufrad (10) vorgesehen.

Figure 00000001
A radial fan with a pot-like impeller (10) is proposed, which is provided with a blade ring (15) on its circumference. A housing (11, 11 ') accommodating the impeller (10) widens radially to an outlet (21) and in the form of a spiral in the direction of rotation of the impeller (10), starting from a part-circle-curved circumferential wall region (19) running directly along the blade ring (15) has two side walls (23, 24) covering the axial end faces of the impeller (10). A partition (26) arranged on one of the side walls (24) engages in the pot-like impeller (10) and divides its interior into a first and a second suction space. A suction opening (28) is assigned to the first suction chamber, and the second suction chamber faces the peripheral wall region (19) running directly along the blade ring (15). Means are provided for the flow sealing of the gaps between the edges of the partition (26) and the impeller (10).
