Abstract
Die Erfindung betrifft einen Diagonallüfter mit einem Gehäuse (10), einem durch einen Elektromotor (11) angetriebenen Laufrad (14), dessen Nabe (12) zusammen mit einem das Laufrad umgebenden Luftführungsmantel (17) einen im wesentlichen ringförmigen Strömungskanal (18) mit einer Lufteintrittöffnung (19) und einer Luftaustrittsöffnung (20) definiert. Die Nabe (12) ist als ein sich zur Luftaustrittöffnung (20) hin verbreiternder Kegelstumpf ausgebildet, wobei der Luftführungsmantel (17) im wesentlichen profiliert ausgebildet ist, wobei der Elektromotor (11) mittels im wesentlichen radial nach außen verlaufenden Stegen (16) im Gehäuse (10) gehalten ist.The invention relates to a diagonal fan with a housing (10), a through an electric motor (11) driven impeller (14), the hub (12) together with an air guide casing (17) surrounding the impeller substantially annular flow channel (18) having an air inlet opening (19) and a Air outlet opening (20) defined. The hub (12) is considered to be an air outlet opening (20). formed widening truncated cone, wherein the air guide casing (17) in is formed substantially profiled, wherein the electric motor (11) means in essentially radially outwardly extending webs (16) held in the housing (10) is.
Die Erfindung zeichnet sich dadurch aus, dass die Stege (16) zur Befestigung des Motors im Bereich der Lufteintrittsöffnung (19) des Strömungskanals (18) angeordnet sind. The invention is characterized in that the webs (16) for mounting the motor in the region of the air inlet opening (19) of the flow channel (18) are arranged.
