Abstract:
(DE) Das Gehäuse (17) eines Lüfters (1) umfasst eine anströmseitige Stirnfläche (2), eine abströmseitige Stirnfläche (16), und einen sich in Richtung einer Achse (12) von einer der Stirnflächen (2) zur anderen (16) erstreckenden, einen Lüfterdurchgang begrenzenden Wandring (15). In dem Lüfterdurchgang ist ein Lüfterrad (10) angeordnet. An der anströmseitigen Stirnfläche (2) ist ein Gitter (3) angeordnet, das eine zentral im Lüfterdurchgang positionierte Nabe (8), in radialer Richtung zwischen der Nabe (8) und dem Rand des Lüfterdurchgangs ausgedehnte primäre Streben (4) und sekundäre Streben (6) aufweist, die die primären Streben (4) kreuzen.
(EN) The housing (17) of a fan (1) comprises an inflow-side end surface (2), an outflow-side end surface (16), and a wall ring (15) which extends in the direction of an axis (12) from one of the end surfaces (2) to the other (16) and bounds a fan passage. A fan wheel (10) is arranged in the fan passage. A grid (3) is arranged on the inflow-side end surface (2), said grid having a hub (8) positioned centrally in the fan passage, primary struts (4) extending in the radial direction between the hub (8) and the edge of the fan passage and secondary struts (6) which intersect the primary struts (4).
(FR) L'invention concerne un ventilateur. Le boîtier (17) d'un ventilateur (1) comporte une face frontale (2) côté flux entrant, une face frontale (16) côté flux sortant, et une bague de paroi (15) limitant un passage du ventilateur et s'étendant en direction d'un axe (12) allant d'une face frontale (2) à l'autre (16). Une roue (10) de ventilateur est agencée dans le passage de ventilateur. Un registre (3) est agencé sur la face frontale (2) côté flux entrant et présente un moyeu (8) positionné de manière centrale dans le passage de ventilateur et des entretoises primaires (4) et des entretoises secondaires (6) s'étendant dans la direction radiale entre le moyeu (8) et le bord du passage de ventilateur, lesquelles entretoises secondaires croisent les entretoises primaires (4).
