Description

Die Erfindung betrifft eine Ventilatoreinrichtung, mit wenigstens einem Radialventilator, mit einem Ventilatorgehäuse, in dem ein um eine Rotationsachse rotatorisch angetriebenes Laufrad angeordnet ist, wobei das Ventilatorgehäuse eines sich in einer Umfangsrichtung des Laufrads spiralförmig herum streckende Leitwand aufweist, die in eine Luftausblasöffnung übergeht, wobei die Leitwand in Umfangsrichtung spiralförmig ausgebildete Leitwandsegmente aufweist, die jeweils in eine eigene Luftausblasöffnung übergehen, derart, dass das Ventilatorgehäuse eine Mehrzahl in Umfangsrichtung des Laufrads verteilt angeordnete Luftausblasöffnungen aufweist. Radialventilatoren können prinzipiell in zwei unterschiedliche Kategorien eingeordnet werden: Die eine Gruppe bilden Radialventilatoren mit Spiralgehäuse und die andere Gruppe freilaufende Radialventilatoren.The invention relates to a fan device, with at least one radial fan, with a fan housing, in which an impeller driven in rotation about an axis of rotation is arranged, the fan housing having a guide wall which extends spirally around in a circumferential direction of the impeller and merges into an air outlet opening, wherein the guide wall has guide wall segments of spiral design in the circumferential direction, each of which merges into its own air outlet opening, such that the fan housing has a plurality of air outlet openings arranged distributed in the circumferential direction of the impeller. Centrifugal fans can basically be divided into two different categories: one group is made up of radial fans with a spiral casing and the other group is free-running radial fans.

Das Spiralgehäuse der Radialventilatoren aus der ersten Gruppe hat zwei Aufgaben zu erfüllen. Es sammelt die aus dem Laufrad ausströmende Luft, führt sie zu einem gemeinsamen Austritt und wandelt einen Teil der Geschwindigkeitsenergie (dynamischer Druck) in Druckenergie (statischer Druck) durch die stetige Querschnittserweiterung in Strömungsrichtung um (Diffusoreffekt). Bei freilaufenden Radialventilatoren wird die Luft im Laufrad in radialer Richtung umgelenkt und strömt dort am Schaufelaustrittsdurchmesser des Laufrads aus. Zur Erhöhung der statischen Wirkungsgrade sind bereits Diffusoren bekannt, bei denen die Deck- und Bodenscheibe des Laufrads über den Schaufelaustrittsdurchmesser hinausstehende äußere Randbereiche aufweist.The spiral casing of the centrifugal fans from the first group has two tasks. It collects the air flowing out of the impeller, leads it to a common outlet and converts part of the speed energy (dynamic pressure) into pressure energy (static pressure) due to the constant cross-sectional expansion in the direction of flow (diffuser effect). In the case of free-running centrifugal fans, the air in the impeller is deflected in the radial direction and flows out there at the blade outlet diameter of the impeller. For Diffusers are already known to increase the static efficiencies, in which the top and bottom disks of the impeller have outer edge regions which project beyond the blade outlet diameter.

EP 0091228 A1 und FR 2220158 A5 offenbaren je eine Ventilatoreinrichtung nach dem Oberbegriff des Anspruchs 1. EP 0091228 A1 and FR 2220158 A5 each disclose a fan device according to the preamble of claim 1.

Aufgabe der Erfindung ist es, eine Ventilatoreinrichtung der eingangs erwähnten Art zu schaffen, die gegenüber herkömmlichen Ventilatoreinrichtungen mit freilaufendem Radialventilator einen verbesserten Wirkungsgrad bei kompakter Bauform aufweist.The object of the invention is to provide a fan device of the type mentioned at the outset which, compared to conventional fan devices with a free-running centrifugal fan, has an improved efficiency with a compact design.

Diese Aufgabe wird durch eine Ventilatoreinrichtung mit den Merkmalen des unabhängigen Anspruchs 1 gelöst. Weiterbildungen der Erfindungen sind in den Unteransprüchen dargestellt.This object is achieved by a fan device with the features of independent claim 1. Further developments of the inventions are presented in the subclaims.

Die erfindungsgemäße Ventilatoreinrichtung ist gekennzeichnet durch ein Klimagehäuse, in dem der Radialventilator aufgenommen ist, wobei der Radialventilator derart in das Klimagehäuse eingesetzt ist, dass zwischen den Luftausblasöffnungen und wenigstens einer zugeordneten Klimagehäusewand des Klimagehäuses eine Ausströmzone ausgebildet ist. Die Erfindung wählt nun einen Ansatz, Radialventilatoren mit Spiralgehäuse derart zu verbessern, dass die Vorteile des Spiralgehäuses - hohe Stabilität, gezielte Luftführung - beibehalten werden und der statische Wirkungsgrad soweit verbessert wird, dass die erfindungsgemäße Ventilatoreinrichtung mit dem Radialventilator mit Spiralgehäuse einen höheren Wirkungsgrad als der freilaufenden Radialventilator aufweist.The fan device according to the invention is characterized by an air-conditioning housing in which the radial fan is accommodated, the radial fan being inserted into the air-conditioning housing in such a way that an outflow zone is formed between the air outlet openings and at least one associated air-conditioning housing wall of the air-conditioning housing. The invention now chooses an approach to improve radial fans with a spiral housing in such a way that the advantages of the spiral housing - high stability, targeted air guidance - are maintained and the static efficiency is improved to such an extent that the fan device according to the invention with the radial fan with a spiral housing has a higher efficiency than that has free-running centrifugal fan.

Im Gegensatz zu dem aus dem Stand der Technik bekannten Ventilatoreinrichtungen mit wenigstens einem Radialventilator mit Spiralgehäuse und einer einzelnen Luftausblasöffnung weist die erfindungsgemäße Ventilatoreinrichtung wenigstens zwei Luftausblasöffnungen auf, d.h. die aus dem Stand der Technik bekannte durch das Spiralgehäuse gebildete Einzel-Spirale wird erfindungsgemäß durch die segmentierte Leitwand in mehrere Teilspiralen aufgeteilt. Die im Laufrad radial umgelenkte Luft wird also im Gegensatz zum Stand der Technik nicht in einer Spirale gesammelt und zur Luftausblasöffnung befördert, sondern sie wird in mehreren Teilspiralen gesammelt und zur jeweiligen Luftausblasöffnung geführt.In contrast to the fan devices known from the prior art with at least one radial fan with volute casing and a single air outlet The fan device according to the invention has at least two air outlet openings, ie the single spiral known from the prior art and formed by the spiral housing is divided into several partial spirals according to the invention by the segmented guide wall. In contrast to the prior art, the air deflected radially in the impeller is therefore not collected in a spiral and conveyed to the air outlet opening, but rather is collected in several partial spirals and guided to the respective air outlet opening.

Dies wirkt sich neben der Steigerung des statischen Wirkungsgrad auch positiv auf die Bauabmessungen aus, die gegenüber herkömmlichen Radialventilatoren mit nur einer Luftausblasöffnung kleiner sind. Dadurch ist die erfindungsgemäße Ventilatoreinrichtung auch geeignet, bei gleichem zu fördernden Volumenstrom gegenüber herkömmlichen Radialventilatoren mit Spiralgehäuse, durch die wesentlich kompaktere Bauweise in jede Anordnung, die ein freies Ansaugen und ein freies Ausblasen ermöglicht, eingebaut zu werden, beispielsweise in kleinere Kanalquerschnitte von Lüftungs- oder Klimagehäusen, beispielsweise Klimakästen oder Klimakanälen.In addition to increasing the static efficiency, this also has a positive effect on the construction dimensions, which are smaller than conventional radial fans with only one air outlet opening. As a result, the fan device according to the invention is also suitable, with the same volume flow to be conveyed, compared to conventional radial fans with a spiral housing, due to the much more compact design, to be installed in any arrangement that enables free suction and free blowing, for example in smaller duct cross sections of ventilation or Air conditioning housings, for example air conditioning boxes or air conditioning ducts.

Bei einer Weiterbildung der Erfindung weisen die Leitwandsegmente jeweils einen inneren Leitwandsegmentabschnitt und einen äußeren Leitwandsegmentabschnitt auf, wobei die Luftausblasöffnungen jeweils von den zueinander benachbarten inneren und äußeren Leitwandsegmentabschnitten der in der Umfangsrichtung des Laufrads jeweils unmittelbar aufeinanderfolgend angeordneten Leitwandsegmente gebildet sind.In a further development of the invention, the guide wall segments each have an inner guide wall segment section and an outer guide wall segment section, the air outlet openings in each case being formed by the mutually adjacent inner and outer guide wall segment sections of the guide wall segments which are arranged directly in succession in the circumferential direction of the impeller.

In besonders bevorzugter Weise sind die Leitwandsegmente außen bogenförmig gekrümmt, wobei zwischen in Umfangsrichtung benachbarten Leitwandsegmenten jeweils ein Luftausblasstutzen absteht, dessen Längsachse parallel oder im Winkel zu einer Tangente an das Laufrad ausgerichtet ist. Insgesamt können also wenigstens zwei Luftausblasstutzen vorgesehen sein, die jeweils die Luftausblasöffnungen begrenzen. Die Querschnittsfläche der Luftausblasöffnungen ist insbesondere rechteckig, beispielsweise quadratisch.In a particularly preferred manner, the guide wall segments are curved on the outside in an arcuate manner, an air outlet connection projecting between each adjacent guide wall segment in the circumferential direction, the longitudinal axis of which is parallel or at an angle to one Tangent is aligned with the impeller. In total, at least two air outlet nozzles can be provided, each of which limit the air outlet openings. The cross-sectional area of the air outlet openings is in particular rectangular, for example square.

Bei einer Weiterbildung der Erfindung liegen von den Luftausblasöffnungen sich wenigstens zwei diametral bezüglich der Rotationsachse des Laufrads gegenüber.In a further development of the invention, at least two of the air outlet openings lie diametrically opposite one another with respect to the axis of rotation of the impeller.

Es ist möglich, dass das Ventilatorgehäuse eine rechteckige Grundform aufweist und sich die Luftausblasöffnungen an den Eckbereichen des Ventilgehäuses befinden.It is possible for the fan housing to have a rectangular basic shape and for the air outlet openings to be located at the corner regions of the valve housing.

In besonders bevorzugter Weise sind vier in Umfangsrichtung des Laufrads verteilt angeordnete Luftausblasöffnungen vorgesehen. Die Luft kann in diesem Fall also von vier Teilspiralen gesammelt und zu den zugeordneten Luftausblasöffnungen gelenkt werden. Im Falle eines rechteckförmigen Ventilatorgehäuses und vier Luftausblasöffnungen, könnte das Ventilatorgehäuse auch als Quad-Gehäuse bezeichnet werden.In a particularly preferred manner, four air outlet openings arranged in the circumferential direction of the impeller are provided. In this case, the air can be collected by four partial spirals and directed to the assigned air outlet openings. In the case of a rectangular fan housing and four air outlet openings, the fan housing could also be referred to as a quad housing.

Bei einer Weiterbildung der Erfindung weist das Ventilatorgehäuse eine mit einer Ansaugöffnung versehene saugseitige Seitenwand und einer eine dieser gegenüberliegende antriebsseitige Seitenwand auf, der ein Ventilatorantrieb zugeordnet ist, wobei zwischen der saugseitigen Seitenwand und der antriebsseitigen Seitenwand das Laufrad aufgenommen ist.In a further development of the invention, the fan housing has a suction-side wall provided with a suction opening and a drive-side wall opposite this, to which a fan drive is assigned, the impeller being accommodated between the suction-side wall and the drive-side wall.

In besonders bevorzugter Weise weist die antriebsseitige Seitenwand eine Befestigungsschnittstelle zur Befestigung eines Ventilatorantriebs auf. Im Vergleich zu freilaufenden Radialventilatoren sind Radialventilatoren mit einem Ventilatorgehäuse stabiler und eignen sich daher zum direkten Anbau des Ventilatorantriebs an das Ventilatorgehäuse. Daher ist die Kombination des Ventilatorgehäuses und dem darin aufgenommenen Laufrad mit dem angebauten Ventilatorantrieb kompakter als der Antrieb plus Laufrad bei einem freilaufenden Radialventilator.In a particularly preferred manner, the drive-side wall has a fastening interface for fastening a fan drive. Compared to free-running centrifugal fans, centrifugal fans are with one Fan housing is more stable and is therefore suitable for direct attachment of the fan drive to the fan housing. Therefore, the combination of the fan housing and the impeller accommodated therein with the attached fan drive is more compact than the drive plus impeller for a free-running centrifugal fan.

Erfindungsgemäß weist die Ventilatoreinrichtung ein Klimagehäuse auf, in dem der Radialventilator aufgenommen ist. Bei dem Klimagehäuse kann es sich beispielsweise um einen Klimakasten, der beispielsweise Bestandteil einer Klimazentrale sein kann, handeln. Alternativ kann es sich bei dem Klimagehäuse auch um einen Klimakanal handeln. Selbstverständlich wäre es auch möglich, den Radialventilator in einem Lüftungsgehäuse, beispielsweise Lüftungskanal, anzuordnen.According to the invention, the fan device has an air conditioning housing in which the radial fan is accommodated. The climate housing can be, for example, a climate box, which can be part of a climate control center, for example. Alternatively, the air conditioning housing can also be an air conditioning duct. Of course, it would also be possible to arrange the radial fan in a ventilation housing, for example a ventilation duct.

Erfindungsgemäß ist der Radialventilator derart in das Klimagehäuse eingesetzt, dass zwischen den Luftausblasöffnungen und einer zugeordneten Klimagehäusewand des Klimagehäuses eine Ausströmzone ausgebildet ist.According to the invention, the radial fan is inserted into the air-conditioning housing in such a way that an outflow zone is formed between the air outlet openings and an associated air-conditioning housing wall of the air-conditioning housing.

Bei einer Weiterbildung der Erfindung weist das Klimagehäuse mehrere beispielsweise vier insbesondere rechtwinklig zueinander ausgerichtete Klimagehäusewände auf, denen jeweils eine Luftausblasöffnung des Radialventilators zugeordnet ist. Zweckmäßigerweise bilden die Mündungsflächen der Luftausblasöffnungen und die jeweils zugeordneten Klimagehäusewände einen Winkel, sind also nicht parallel zueinander angeordnet, wodurch sich ein optimierter Luftaustritt verwirklichen lässt. Es ist also möglich, den Radialventilator ein Stückweit verdreht gegenüber den Klimagehäusewänden in das Klimagehäuse einzusetzen, wodurch die Luftausblasöffnungen in Richtung der Ecken zwischen den zueinander benachbarten Klimagehäusewänden fokussiert werden.In a further development of the invention, the air conditioning housing has a plurality of, for example, four air conditioning housing walls, in particular at right angles to one another, each of which is assigned an air outlet opening of the radial fan. The outlet surfaces of the air outlet openings and the associated air conditioning housing walls expediently form an angle, that is to say are not arranged parallel to one another, as a result of which an optimized air outlet can be achieved. It is therefore possible to insert the centrifugal fan a little bit rotated relative to the climate housing walls into the climate housing, as a result of which the air outlet openings in Direction of the corners between the adjacent climate housing walls can be focused.

Bei einer Weiterbildung der Erfindung weist die Ventilatoreinrichtung eine unter einer Gehäusedecke hängende Zwischendecke auf, in der der Radialventilator aufgenommen ist.In a development of the invention, the fan device has an intermediate ceiling hanging under a housing ceiling, in which the radial fan is accommodated.

Es ist möglich, dass die Ventilatoreinrichtung einen oberhalb eines Gehäusebodens angeordneten Zwischenboden aufweist, in dem der Radialventilator aufgenommen ist.It is possible for the fan device to have an intermediate floor which is arranged above a housing base and in which the radial fan is accommodated.

Die Figuren 1 und 2 zeigen ein erstes Ausführungsbeispiel der erfindungsgemäßen Ventilatoreinrichtung 11. Der Hauptbestandteil der Ventilatoreinrichtung 11 ist ein Radialventilator 12 der ein Ventilatorgehäuse 13 besitzt, in dem ein um eine Rotationsachse 14 rotatorisch angetriebenes Laufrad 15 angeordnet ist.The Figures 1 and 2 show a first embodiment of the fan device 11 according to the invention. The main component of the fan device 11 is a radial fan 12 which has a fan housing 13 in which an impeller 15 which is driven in rotation about an axis of rotation 14 is arranged.

Das Ventilatorgehäuse 13 ist kastenförmig ausgebildet und besitzt zwei parallel zueinander ausgerichtete Seitenwände 17, 18, die beabstandet zueinander angeordnet sind, wobei im Zwischenraum zwischen den beiden Seitenwänden das Laufrad 15 aufgenommen ist.The fan housing 13 is box-shaped and has two parallel side walls 17, 18 which are arranged at a distance from one another, the impeller 15 being accommodated in the space between the two side walls.

Es ist eine saugseitige Seitenwand 17 vorgesehen, die mit einer Eintrittsöffnung (nicht dargestellt) versehen ist, die einen Ansaugdurchmesser definiert. Die Eintrittsöffnung befindet sich an der Außenseite der saugseitigen Seitenwand 17, wobei sich die durchströmende Fläche entsprechend der Kontur der saugseitigen Seitenwand 17 beispielseise trompetenförmig erweitern kann.A suction side wall 17 is provided, which is provided with an inlet opening (not shown) which defines an intake diameter. The inlet opening is located on the outside of the suction side wall 17, the area flowing through being able to widen in a trumpet shape, for example in accordance with the contour of the suction side wall 17.

Gegenüberliegend zur ansaugseitigen Seitenwand 17 ist die antriebsseitige Seitenwand 18 angeordnet. An der antriebsseitigen Seitenwand 18 befindet sich eine Befestigungsschnittstelle 19, an der der Ventilatorantrieb 16 befestigt ist. Wie insbesondere in Figur 1 dargestellt, umfasst die Befestigungsschnittstelle 19 einen Antriebsträger 20 in Form eines Befestigungsflanschs, auf dem der Ventilatorantrieb 16 montiert ist. Bei dem Ventilatorantrieb 16 handelt es sich vorzugsweise um einen Elektromotor, insbesondere um einen permanentmagneterregten Synchronmotor. Es ist jedoch auch möglich, den Ventilatorantrieb 16 als Asynchronmotor auszugestalten.The drive-side wall 18 is arranged opposite the suction-side wall 17. On the drive side wall 18 there is an attachment interface 19 to which the fan drive 16 is attached. As especially in Figure 1 shown, the mounting interface 19 comprises a drive bracket 20 in the form of a mounting flange on which the fan drive 16 is mounted. The fan drive 16 is preferably an electric motor, in particular a permanent magnet-excited synchronous motor. However, it is also possible to design the fan drive 16 as an asynchronous motor.

Infolge der hohen Stabilität des Ventilatorgehäuses 13 lässt sich der Antriebsträger 20 mitsamt dem Ventilantrieb 16 direkt am Ventilatorgehäuse 13 an der Befestigungsschnittstelle 19 montieren. Hierzu wird der flanschartige Antriebsträger 20 an die Außenseite der antriebsseitigen Seitenwand 18 angesetzt und dort mittels geeigneter Befestigungsmittel befestigt, beispielsweise mittels Befestigungsschrauben angeschraubt. Die Antriebswelle des Ventilatorantriebs 16 ragt durch eine Öffnung ins Innere des Ventilatorgehäuses und trägt das Laufrad 15, das - wie erwähnt - im Betriebszustand im Innern des Ventilatorgehäuses 13 rotiert.As a result of the high stability of the fan housing 13, the drive carrier 20 together with the valve drive 16 can be mounted directly on the fan housing 13 at the fastening interface 19. For this purpose, the flange-like drive carrier 20 is attached to the outside of the drive-side wall 18 and fastened there by means of suitable fastening means, for example screwed on using fastening screws. The drive shaft of the fan drive 16 projects through an opening into the interior of the fan housing and carries the impeller 15 which, as mentioned, rotates in the interior of the fan housing 13 in the operating state.

Das Laufrad 15 besitzt einen Schaufelkranz 21, der aus mehreren Schaufeln 22 besteht, die beispielsweise von innen nach außen gegen die Laufrichtung geneigt sein können.The impeller 15 has a blade ring 21, which consists of a plurality of blades 22, which can be inclined, for example, from the inside to the outside in the direction of rotation.

Wie insbesondere in Figur 1 dargestellt, sind die Schaufeln 22 beispielhaft in Form von rückwärts gekrümmten Schaufeln 22 dargestellt. Alternativ wäre es jedoch auch möglich, rückwärts geneigte gerade Schaufeln 22 einzusetzen.As especially in Figure 1 shown, the blades 22 are shown by way of example in the form of backward curved blades 22. Alternatively, however, it would also be possible to use straight blades 22 which are inclined backwards.

Das Ventilatorgehäuse 13 des Radialventilators 12 ist als Spiralgehäuse ausgeführt, das die Aufgabe hat, die vom Laufrad 15 in radialer Richtung umgelenkte Luft zu sammeln und zu einem gemeinsamen Luftaustritt, einer Luftausblasöffnung 23, zu führen. Dabei wird ein Teil der Geschwindigkeitsenergie (dynamischer Druck) in Druckenergie (statischer Druck) durch die stetige Querschnittserweiterung in Strömungsrichtung umgewandelt.The fan housing 13 of the radial fan 12 is designed as a spiral housing, which has the task of collecting the air deflected in the radial direction by the impeller 15 and of leading it to a common air outlet, an air outlet opening 23. Part of the speed energy (dynamic pressure) is converted into pressure energy (static pressure) due to the constant cross-sectional expansion in the direction of flow.

Das Ventilatorgehäuse 13 besitzt hierzu eine sich in einer Umfangsrichtung 24 des Laufrads 15 spiralförmig herumstreckende Leitwand 25, die in die Luftausblasöffnung 23 übergeht. Die Leitwand 25 bildet den umfangsseitigen Abschluss der Seitenwände 17, 18 und bildet gemeinsam mit diesen das kastenförmige Ventilatorgehäuse 13.For this purpose, the fan housing 13 has a guide wall 25 which extends spirally in a circumferential direction 24 of the impeller 15 and merges into the air outlet opening 23. The guide wall 25 forms the peripheral end of the side walls 17, 18 and, together with these, forms the box-shaped fan housing 13.

Der erfindungsgemäße Radialventilator 12 besitzt nun eine in Umfangsrichtung 24 segmentierte Leitwand 25, die eine Mehrzahl für sich jeweils spiralförmig ausgebildete Leitwandsegmente 27a-d aufweist, die jeweils in eine eigene Luftausblasöffnung 23a-d übergehen, derart, dass das Ventilatorgehäuse 13 eine Mehrzahl in Umfangsrichtung des Laufrads 15 verteilt angeordnete Luftausblasöffnungen 23a-d aufweist. Im gezeigten Beispielsfall ist die Leitwand 25 in vier Leitwandsegmente 27a-d segmentiert und es sind in Umfangsrichtung 24 des Laufrads 15 verteilt vier Luftausblasöffnungen 23a-d vorgesehen. Es ist selbstverständlich möglich, dass die Zahl der Leitwandsegmente 27a-d und die Zahl der Luftausblasöffnungen 23a-d von vier abweicht, nämlich zwei, drei oder mehr als fünf an der Zahl beträgt.The radial fan 12 according to the invention now has a guide wall 25 which is segmented in the circumferential direction 24 and which has a plurality of guide wall segments 27a-d which are each of a spiral configuration and each of which merges into its own air outlet opening 23a-d, such that the fan housing 13 has a plurality in the circumferential direction of the Impeller 15 has distributed air outlet openings 23a-d. In the example shown, the guide wall 25 is segmented into four guide wall segments 27a-d and there are four air outlet openings 23a-d distributed in the circumferential direction 24 of the impeller 15. It is of course possible for the number of guide wall segments 27a-d and the number of air outlet openings 23a-d to deviate from four, namely two, three or more than five in number.

Wie insbesondere in Figur 1 dargestellt, besitzen die Leitwandsegmente 27a-d jeweils einen inneren Leitwandsegmentabschnitt 28a-d und einen äußeren Leitwandsegmentabschnitt 29a-d, wobei die Luftausblasöffnungen 23a-d jeweils von den zueinander benachbarten inneren und äußeren Leitwandsegmentabschnitten 28a-d; 29a-d der in der Umfangsrichtung 24 des Laufrads 15 jeweils unmittelbar aufeinanderfolgend angeordneten Leitwandsegmente 27a-d gebildet sind.As especially in Figure 1 shown, the guide wall segments 27a-d each have an inner guide wall segment section 28a-d and an outer guide wall segment section 29a-d, the air discharge openings 23a-d of the mutually adjacent inner and outer guide wall segment sections 28a-d; 29a-d of the guide wall segments 27a-d arranged in direct succession in the circumferential direction 24 of the impeller 15 are formed.

Wie weiter in Figur 1 dargestellt, liegen die Mündungsflächen einander benachbarter Luftausblasöffnungen 23a-d im rechten Winkel zueinander. Das Ventilatorgehäuse 13 weist im gezeigten Beispielsfall eine rechteckförmige, insbesondere quadratische Grundform auf, wobei die Leitwandsegmente 27a-d die Umfangsseiten des quaderförmig ausgebildeten Ventilatorgehäuses 13 bilden.As further in Figure 1 shown, the mouth surfaces of adjacent air outlet openings 23a-d are at right angles to each other. In the example shown, the fan housing 13 has a rectangular, in particular square, basic shape, the guide wall segments 27a-d forming the peripheral sides of the rectangular-shaped fan housing 13.

Im Beispielsfall liegen sich jeweils zwei Luftausblasöffnungen 27a,c und 27b,d diametral zur Rotationsachse 14 einander gegenüber. Übertragen auf das quaderartige bzw. kastenartige Ventilatorgehäuse 13 bedeutet dies, dass die Luftausblasöffnungen 23a-d jeweils an den Eckbereichen des Ventilatorgehäuses 13 sitzen.In the example, two air outlet openings 27a, c and 27b, d lie opposite each other diametrically to the axis of rotation 14. Transferred to the cuboid or box-like fan housing 13, this means that the air outlet openings 23a-d each sit at the corner regions of the fan housing 13.

Wie ferner in Figur 1 gezeigt, sind die Leitwandsegmente 27a-d jeweils außen bogenförmig gekrümmt, wobei zwischen in Umfangsrichtung 24 benachbarten Leitwandsegmenten 27a-d jeweils ein Luftausblasstutzen 30a-d absteht, dessen Längsachse parallel oder im Winkel zu einer Tangente an das Laufrad 15 ausgerichtet ist.As further in Figure 1 are shown, the guide wall segments 27a-d are each curved in the shape of an outside, an air outlet connector 30a-d projecting between guide wall segments 27a-d adjacent in the circumferential direction 24, the longitudinal axis of which is oriented parallel to or at an angle to a tangent to the impeller 15.

Jeder dieser Luftausblasstutzen 30a-d stellt den Austrittsbereich einer Teilspirale dar, die jeweils einen Teil der vom Laufrad 15 radial umgelenkten Luft sammelt und zur zugeordneten Luftausblasöffnung 23a-d führt. Bei einer nicht dargestellten Variante können die Mündungsebenen der Luftausblasstutzen 30a-d gegenüber den äußeren Leitwandsegmentabschnitten 29a-d hinausragen oder zurückgesetzt sein.Each of these air outlet nozzles 30a-d represents the outlet area of a partial spiral, which in each case collects part of the air radially deflected by the impeller 15 and leads to the associated air outlet opening 23a-d. In a variant not shown, the outlet levels of the air outlet spigot 30a-d protrude or be set back from the outer guide wall segment sections 29a-d.

Die Figur 3 zeigt in schematischer Darstellung eine Ventilatoreinrichtung aus dem Stand der Technik, bei der der Radialventilator ein Spiralgehäuse mit einer einzelnen Luftausblasöffnung besitzt. Im selben Schaubild ist das zuvor beschriebene erste Ausführungsbeispiel der erfindungsgemäßen Ventilatoreinrichtung 11 dargestellt, bei dem das Ventilatorgehäuse 13 vier in Umfangsrichtung 24 des Laufrads 15 verteilt angeordnete Luftausblasöffnungen 23a-d aufweist.The Figure 3 shows a schematic representation of a fan device from the prior art, in which the radial fan has a spiral housing with a single air outlet opening. The same diagram shows the previously described first exemplary embodiment of the fan device 11 according to the invention, in which the fan housing 13 has four air outlet openings 23a-d which are arranged distributed in the circumferential direction 24 of the impeller 15.

Ebenfalls in Figur 3 dargestellt ist ein zweites Ausführungsbeispiel der erfindungsgemäßen Ventilatoreinrichtung 11, bei der das Ventilatorgehäuse 13 des Radialventilators 12 zwei in Umfangsrichtung 24 des Laufrads 15 verteilt angeordnete Luftausblasöffnungen 23a,b aufweist.Also in Figure 3 Shown is a second exemplary embodiment of the fan device 11 according to the invention, in which the fan housing 13 of the radial fan 12 has two air outlet openings 23a, b which are distributed in the circumferential direction 24 of the impeller 15.

Wie insbesondere die Zusammenschau der verschiedenen erfindungsgemäßen Ventilatoreinrichtungen 11 und der Ventilatoreinrichtung aus dem Stand der Technik zeigt, ist die Baugröße der erfindungsgemäßen Ventilatoreinrichtungen 11 deutlich geringer als diejenige der Ventilatoreinrichtung aus dem Stand der Technik.As the combination of the various fan devices 11 according to the invention and the fan device from the prior art shows in particular, the size of the fan devices 11 according to the invention is significantly smaller than that of the fan device from the prior art.

Wie ferner die Figuren 4 bis 6 zeigen, ist sowohl die Baubreite B' des ersten Ausführungsbeispiels als auch die Baubreite B" des zweiten Ausführungsbeispiels kleiner als die Baubreite B des Spiralgehäuses aus dem Stand der Technik. Gleiches gilt für die Bauhöhe: Die Bauhöhe H' und auch die Bauhöhe H" ist deutlich kleiner als die Bauhöhe H des Spiralgehäuses aus dem Stand der Technik. Die deutlich kompakteren Abmessungen der erfindungsgemäßen Ventilatoreinrichtungen 11 ermöglichen gegenüber Ventilatoreinrichtungen aus dem Stand der Technik mit denselben Volumenströmen eine erhebliche Einsparung des Platzbedarfs.Like further the Figures 4 to 6 show, both the width B 'of the first embodiment and the width B "of the second embodiment are smaller than the width B of the spiral casing from the prior art. The same applies to the height: The height H' and also the height H" significantly smaller than the height H of the spiral housing from the prior art. The significantly more compact dimensions of the fan devices 11 according to the invention make it possible to use fan devices from the State of the art with the same volume flows a considerable saving in space requirements.

Die Figur 7 zeigt ein drittes Ausführungsbeispiel der erfindungsgemäßen Ventilatoreinrichtung 11. Die Ventilatoreinrichtung 11 des dritten Ausführungsbeispiels umfasst neben einem Radialventilator 12 noch ein Klimagehäuse 31, in dem der Radialventilator 12 eingebaut ist. Das Klimagehäuse 31 ist beispielhaft in Form eines Klimakastens gezeigt, der einen rechteckigen, insbesondere quadratischen Querschnitt aufweist und im gezeigten Beispielsfall vier rechtwinklig zueinander ausgerichtete Klimagehäusewände 32a-d besitzt. Zur Befestigung des Radialventilators 12 im Klimagehäuse 31 dient beispielsweise eine im Klimagehäuse 31 befestigte Trennwand (nicht dargestellt), an der der Radialventilator 12 mittels geeigneter Befestigungsmittel befestigt werden kann. Die Befestigung des Radialventilators 12 an der Trennwand erfolgt vorzugsweise an der saugseitigen Seitenwand 17 des Ventilatorgehäuses 13. Alternativ ist es auch denkbar, den Radialventilator mittels einer Ständerkonstruktion, beispielsweise L-förmiger Ständer, oder einer Fußkonstruktion im Kanalgehäuse unterzubringen.The Figure 7 shows a third exemplary embodiment of the fan device 11 according to the invention. In addition to a radial fan 12, the fan device 11 of the third exemplary embodiment also comprises an air-conditioning housing 31 in which the radial fan 12 is installed. The air conditioning housing 31 is shown by way of example in the form of an air conditioning box which has a rectangular, in particular square, cross section and, in the example shown, has four air conditioning housing walls 32a-d oriented at right angles to one another. For attaching the radial fan 12 in the air conditioning housing 31 is used, for example, a partition wall (not shown) fastened in the air conditioning housing 31, to which the radial fan 12 can be attached by means of suitable fastening means. The radial fan 12 is preferably attached to the partition wall on the suction side wall 17 of the fan housing 13. Alternatively, it is also conceivable to accommodate the radial fan in the duct housing by means of a stand construction, for example an L-shaped stand, or a foot construction.

Wie insbesondere in Figur 7 dargestellt, ist jede Klimagehäusewand 32a-d eine Luftausblasöffnung 23a-d des Radialventilators 12 zugeordnet. Jedoch sind die Mündungsflächen der Luftausblasöffnungen 23a-d nicht parallel zu den zugeordneten Klimagehäusewänden 32a-d angeordnet, sondern bilden mit der zugeordneten Klimagehäusewand 32a-d einen Winkel. Mit anderen Worten, der Radialventilator 12 ist gegenüber den Klimagehäusewänden 32a-d in einer Rotationslage angeordnet, bei der die Leitwandsegmente 27a-d im Winkel 0° < α < 90°, insbesondere 5° < α < 45° gegenüber den zugeordneten Klimagehäusewänden 32a-d ausgerichtet sind.As especially in Figure 7 each air-conditioning housing wall 32a-d is assigned an air outlet opening 23a-d of the radial fan 12. However, the mouth surfaces of the air outlet openings 23a-d are not arranged parallel to the associated air-conditioning housing walls 32a-d, but form an angle with the assigned air-conditioning housing wall 32a-d. In other words, the radial fan 12 is arranged in a rotational position with respect to the air conditioning housing walls 32a-d, in which the guide wall segments 27a-d are at an angle of 0 ° <α <90 °, in particular 5 ° <α <45 ° with respect to the associated climate housing walls 32a-d.

Eine derartige Anordnung des Radialventilators 12 erlaubt einen optimierten Luftaustritt durch die einzelnen Luftausblasöffnungen 23a-d. Die Luftausblasöffnungen 23a-d bzw. die Luftausblasstutzen 30a-d sind mit ihren Längsachsen in Richtung der Ecken zwischen zwei benachbarten Klimagehäusewänden 32a-d ausgerichtet.Such an arrangement of the radial fan 12 allows an optimized air outlet through the individual air outlet openings 23a-d. The air outlet openings 23a-d and the air outlet ports 30a-d are aligned with their longitudinal axes in the direction of the corners between two adjacent air conditioning housing walls 32a-d.

Zwischen den Luftausblasöffnungen 23a-d bzw. zwischen deren Mündungsflächen und der zugeordneten Klimagehäusewände 32a-d bildet sich somit eine charakteristische Ausströmzone, die zu geringen Verlusten im Ausblasbereich führt. Ein solcher Klimakasten kann beispielsweise Bestandteil einer Klimazentrale sein, die neben dem Radialventilator 12 noch weitere Komponenten, beispielsweise Filter, usw. enthält.A characteristic outflow zone thus forms between the air outlet openings 23a-d or between their outlet surfaces and the associated air conditioning housing walls 32a-d, which leads to low losses in the outlet area. Such a climate box can be part of a climate control center, for example, which in addition to the radial fan 12 also contains other components, for example filters, etc.
