Description

Die Erfindung betrifft eine Befestigungsvorrichtung eines Lüfters, insbesondere eines Wandring-Axial-Ventilators.The invention relates to a fastening device for a fan, in particular a wall ring axial fan.

Ein verbreiteter Anwendungsfall von Lüftern ist die Verwendung als Kühlvorrichtung an abwärmeproduzierenden Geräten. Solche abwärmeproduzierenden Geräte können beispielsweise Wärmetauscher sein, wobei der Lüfter unmittelbar an dem Wärmetauscher oder an einem den Wärmetauscher aufnehmenden Gehäuse befestigt wird. Lüfter für solche Anwendungsfälle können einen Wandring aufweisen, über den die Befestigung vorgenommen wird. Dazu sind Bohrungen und teilweise Gewindeeinsätze an der Stirnseite des Wandringes vorgesehen. Diese Befestigungsart ist beispielsweise bei den bisher meist eingesetzten Lamellen-Wärmetauschern weit verbreitet.A common application of fans is the use as a cooling device on waste heat-producing devices. Such waste heat-producing devices can, for example, be heat exchangers, the fan being attached directly to the heat exchanger or to a housing accommodating the heat exchanger. Fans for such applications can have a wall ring over which the attachment is made. For this purpose, holes and partially threaded inserts are provided on the end face of the wall ring. This type of attachment is widely used, for example, in the finned heat exchangers that have mostly been used to date.

Aus Kostengründen tauchen am Markt aber auch zunehmend andere Bauformen von Wärmetauschern auf, die einen direkten Anbau eines Lüfters über den Wandring nicht zulassen. Bekannte Lösungen für dieses Problem, bei dem die Befestigung des Antriebsmotors des Ventilators über einen U-Bügel mit dem Bodenblech eines Gerätes unter Verzicht auf einen Wandring erfolgt, haben Nachteile hinsichtlich Wirkungsgrad und Geräuschentwicklung.For cost reasons, however, other types of heat exchangers are increasingly appearing on the market that do not allow a fan to be attached directly via the wall ring. Known solutions to this problem, in which the drive motor of the fan is attached via a U-bracket to the base plate of a device without a wall ring, have disadvantages with regard to efficiency and noise.

So offenbart die deutsche Offenlegungsschrift DE 10 2012 109 516 A1 ein Trägerelement zur Halterung eines Ventilators, insbesondere eines Axialventilators, mit einem Wandring zur Aufnahme des Ventilators. Der Wandring weist an seinem Außenumfang ein Scharnier auf, das aus einem mit dem Wandring verbundenen ersten Scharnierteil und einem relativ zu dem ersten Scharnierteil um eine Scharnierachse schwenkbaren zweiten Scharnierteil besteht.So the German laid-open publication discloses DE 10 2012 109 516 A1 a carrier element for holding a fan, in particular an axial fan, with a wall ring for receiving the fan. On its outer circumference, the wall ring has a hinge which consists of a first hinge part connected to the wall ring and a second hinge part which can be pivoted relative to the first hinge part about a hinge axis.

Die deutsche Patentschrift DE 10 2010 045 899 B3 offenbart eine Ventilatoreinheit mit einem festen Tragring und einem in dem Tragring angeordneten elektrischen Axialventilator, wobei der Tragring mittels Aufhängegliedern in einem Montagegehäuse befestigt ist. Zur verbesserten Schwingungs- und Geräuschdämpfung wird vorgeschlagen, dass der Tragring mehrere umfangsverteilt angeordnete Haltezapfen aufweist, die zum Aufstecken jeweils eines aus einem elastomeren Werkstoff bestehenden Aufhängeglieds ausgebildet sind, und die Aufhängeglieder korrespondierende Stecköffnungen zum Aufstecken auf die Haltezapfen aufweisen.The German patent specification DE 10 2010 045 899 B3 discloses a fan unit with a fixed support ring and an electrical axial fan arranged in the support ring, the support ring being fastened in a mounting housing by means of suspension members. For improved vibration and noise damping, it is proposed that the support ring have a plurality of circumferentially distributed holding pins which are each designed to attach a suspension member made of an elastomeric material, and the suspension members have corresponding plug-in openings for attaching to the retaining pins.

Die US-amerikanische Offenlegungsschrift US 2014 / 0056693 A offenbart einen Ventilator mit einem Lüfterrahmen und einem Lüfterrad. Der Lüfterrahmen weist einen Rahmenkörper und mindestens zwei schwingungsfeste Elemente auf. Der Rahmenkörper hat mindestens zwei Positionierungsrippen, wobei die wenigstens zwei Positionierungsrippen aus einer Seitenwand des Rahmenkörpers herausragen und symmetrisch verteilt sind. Jedes der schwingungsfesten Elemente weist eine Positioniernut auf. Die Positionierungsrippe des Rahmenkörpers ist in der Lage, in der Positionierungsrille des schwingungsfesten Elements einzugreifen, um das schwingungsfeste Element auf der Seitenwand des Rahmenkörpers zu positionieren. Das Lüfterrad ist drehbar in dem Lüfterrahmen angeordnet.The United States patent application US 2014/0056693 A discloses a fan with a fan frame and a fan wheel. The fan frame has a frame body and at least two vibration-resistant elements. The frame body has at least two positioning ribs, the at least two positioning ribs protruding from a side wall of the frame body and being distributed symmetrically. Each of the vibration-proof elements has a positioning groove. The positioning rib of the frame body is capable of engaging in the positioning groove of the vibration-proof member to position the vibration-proof member on the side wall of the frame body. The fan wheel is rotatably arranged in the fan frame.

Die US-amerikanische Offenlegungsschrift US 2010 / 0111698 A offenbart eine Luftstromvorrichtung, die einen Statorabschnitt, mindestens eine Statorschaufel und eine Vielzahl von Befestigungsflanschen auf dem Statorabschnitt aufweist. Zusätzlich weist die Luftströmungsvorrichtung zumindest einen Schlitz zwischen mehreren Montageflanschen, eine Rotoranordnung mit der zumindest die eine Statorschaufel gekoppelt ist, wobei die Rotoranordnung ein proximales Ende und ein distales Ende aufweist. Weiterhin umfasst die Luftstromvorrichtung wenigstens eine Ventilatorschaufel, die an die Rotoranordnung gekoppelt ist. Die Luftstromvorrichtung umfasst weiterhin eine Verriegelungsvorrichtung, wobei die Verriegelungsvorrichtung mindestens ein Befestigungselement und mindestens ein Kopplungselement aufweist, wobei der mindestens eine Schlitz an dem mindestens einen Kopplungselement gekoppelt ist.The United States patent application US 2010/0111698 A discloses an airflow device having a stator section, at least one stator blade, and a plurality of mounting flanges on the stator section. In addition, the air flow device has at least one slot between a plurality of mounting flanges, a rotor arrangement to which at least one stator blade is coupled, the rotor arrangement having a proximal end and a distal end.

Aufgabe der Erfindung ist es daher, eine Befestigungsvorrichtung eines Wandring-Axial-Ventilators anzugeben, die in Einsatzfällen einsetzbar ist, in denen der Lüfter an einer anderen Bauform als einem Lamellen-Wärmetauscher unter Beibehaltung des Wandrings befestigt werden soll. Insbesondere soll diese Befestigungsmöglichkeit optional möglich sein, so dass die konventionelle Befestigung des Wandring-Axial-Ventilators weiterhin uneingeschränkt möglich ist.The object of the invention is therefore to provide a fastening device of a wall ring axial fan, which can be used in applications in which the fan is to be fastened to a design other than a lamella heat exchanger while maintaining the wall ring. In particular, this fastening option should be optionally possible, so that the conventional fastening of the wall ring axial fan is still possible without restriction.

Erfindungsgemäß wird diese Aufgabe durch ein Befestigungssystem mit den Merkmalen des unabhängigen Anspruches 1 gelöst. Vorteilhafte Weiterbildungen des Befestigungssystems ergeben sich aus den Unteransprüchen 2 - 6.According to the invention, this object is achieved by a fastening system with the features of independent claim 1. Advantageous further developments of the fastening system result from subclaims 2-6.

Ein erfindungsgemäßes Befestigungssystem ist zur Befestigung eines Wandring-Axial-Ventilators an einem Gerät vorgesehen. Das Befestigungssystem ist mit einem Wandring als Befestigungsvorrichtung, einem Ventilator und einem Haltemittel versehen, wobei die Befestigungsvorrichtung in radialer Richtung um den Ventilator herum vorgesehen ist und der Ventilator über das Haltemittel mit der Befestigungsvorrichtung verbunden ist. Die Befestigungsvorrichtung weist eine erste Befestigungsgeometrie auf. Das Befestigungssystem umfasst die Befestigungsvorrichtung und weist zusätzlich eine Haltevorrichtung auf, wobei die Befestigungsvorrichtung mindestens eine weitere, zweite Befestigungsgeometrie zur Befestigung der Haltevorrichtung an der Befestigungsvorrichtung aufweist. Über die erste Befestigungsgeometrie kann die Befestigungsvorrichtung und damit der Wandring-Axial-Ventilator in herkömmlicher Weise an einem Gerät befestigt werden. Beispielsweise besteht die erste Befestigungsgeometrie aus Bohrungen in einem Flansch der Befestigungsvorrichtung, so dass der Wandring-Axial-Ventilator in eine ringförmige Öffnung wie die Wand eines Wärmetauschers oder eines Wärmetauschergehäuses eingebaut werden und mittels eines Befestigungsmittels, beispielsweise einer Schraube, befestigt werden kann. Die zweite Befestigungsgeometrie dient der Befestigung der Haltevorrichtung an der Befestigungsvorrichtung, so dass der Wandring-Axial-Ventilator über die Haltevorrichtung an einer anderen Bauform eines Geräts als einem Lamellen-Wärmetauscher, beispielsweise an einem Bodenblech einer Wärmetauscher-Einheit, befestigt werden kann. Ein und derselbe Wandring-Axial-Ventilator kann durch die Verwendung unterschiedlicher Haltevorrichtung an kundenspezifische Einbausituationen wie beispielsweise unterschiedliche Einbauhöhen oder unterschiedliche Befestigungspositionen, angepasst werden, ohne den zugrundeliegenden Wandring-Axial-Ventilator selbst zu verändern.A fastening system according to the invention is provided for fastening a wall ring axial fan to a device. The fastening system is provided with a wall ring as a fastening device, a fan and a holding means, the fastening device being provided in the radial direction around the fan and the fan being connected to the fastening device via the holding means. The fastening device has a first fastening geometry. The fastening system comprises the fastening device and additionally has a holding device, the fastening device having at least one further, second fastening geometry for fastening the holding device to the fastening device. The fastening device and thus the wall ring axial fan can be fastened to a device in a conventional manner via the first fastening geometry. For example, the first fastening geometry consists of bores in a flange of the fastening device, so that the wall ring axial fan can be installed in an annular opening such as the wall of a heat exchanger or a heat exchanger housing and can be fastened by means of a fastening means, for example a screw. The second fastening geometry is used to fasten the holding device to the fastening device, so that the wall ring axial fan, via the holding device, is designed on a construction of a device other than a lamella heat exchanger, for example on a base plate of a heat exchanger unit. can be attached. One and the same wall ring axial fan can be adapted to customer-specific installation situations such as different installation heights or different mounting positions by using different holding devices, without changing the underlying wall ring axial fan itself.

Die zweite Befestigungsgeometrie ist am Umfang der Befestigungsvorrichtung vorgesehen. Erfindungsgemäß weist die Befestigungsvorrichtung an ihrem Umfang einen Kragen auf, wobei die zweite Befestigungsgeometrie am Umfang des Kragens vorgesehen ist. Die zweite Befestigungsgeometrie weist eine erste Führung auf, in die die Haltevorrichtung einsteckbar ist, wobei der Außendurchmesser der ersten Führung höchstens gleich groß ist wie der maximale Außendurchmesser der Befestigungsvorrichtung. Damit ist eine Montage in eine ringförmige Öffnung trotz der zusätzlichen ersten Führung behinderungsfrei möglich. Die erste Führung ist dabei als Schwalbenschwanzführung ausgeführt und kann beispielsweise eine Trapezform oder eine Zylinderform aufweisen.The second fastening geometry is provided on the circumference of the fastening device. According to the invention, the fastening device has a collar on its circumference, the second fastening geometry being provided on the circumference of the collar. The second fastening geometry has a first guide into which the holding device can be inserted, the outer diameter of the first guide being at most the same size as the maximum outer diameter of the fastening device. Installation in an annular opening is thus possible without hindrance despite the additional first guide. The first guide is designed as a dovetail guide and can have a trapezoidal shape or a cylindrical shape, for example.

Erfindungsgemäß weist die Haltevorrichtung mindestens eine zweite Führung auf, die mit der ersten Führung der zweiten Befestigungsgeometrie wirkverbindbar ist. Beispielsweise kann die Haltevorrichtung mit ihrer zweiten Führung in die erste Führung der Befestigungsvorrichtung eingeschoben werden. Die Führungen von der zweiten Befestigungsgeometrie und der Haltevorrichtung weisen sich entsprechende Schrägen in axialer Richtung auf. Dadurch können die beiden Teile leicht gefügt werden und sitzen in der Endlage dennoch spielfrei. Darüber hinaus können die Schrägen als Entformungsschrägen dienen, wenn die Teile gegossen sind. Beispielsweise können die Befestigungsvorrichtung als auch die Haltevorrichtung aus einem Kunststoff, beispielsweise einem thermoplastischen oder auch einem duroplastischen Kunststoff, hergestellt sein. Dafür bietet sich das Spritzgußverfahren an, bei dem für die Entformung aus der Form Schrägen in Entformungsrichtung an den Spritzgussteilen vorteilhaft sind.According to the invention, the holding device has at least one second guide which can be operatively connected to the first guide of the second fastening geometry. For example, the holding device can be inserted with its second guide into the first guide of the fastening device. The guides of the second fastening geometry and the holding device have corresponding bevels in the axial direction. As a result, the two parts can be easily joined and still sit without play in the end position. In addition, the bevels can serve as draft angles when the parts are cast. For example, the fastening device and the holding device can be made of a plastic, for example a thermoplastic or also a thermosetting plastic. The injection molding process lends itself to this, in which bevels in the demolding direction on the injection molded parts are advantageous for demolding from the mold.

In einer weiteren vorteilhaften Ausführungsform weist die Befestigungsvorrichtung mindestens ein erstes Indexierungsmittel auf, wobei die Haltevorrichtung ein zweites Indexierungsmittel aufweist, das mit dem ersten Indexierungsmittel bei der Montage von Haltevorrichtung mit der Befestigungsvorrichtung zusammen wirkt. Beispielsweise kann das erste Indexierungsmittel einen axialen Vorsprung an der Außengeometrie des Kragens der Befestigungsvorrichtung aufweisen, während das zweite Indexierungsmittel eine in axialer Richtung verlaufende Nut am Innendurchmesser der Haltevorrichtung aufweist. So kann das erste Indexierungsmittel beispielsweise aus der Verlängerung mindestens eines Haltemittels bestehen, das über den Außendurchmesser des Kragens hinausragt. Das zweite Indexierungsmittel kann zunächst in das erste Indexierungsmittel eingeschoben werden, bevor die Führungen in Eingriff kommen. Durch das Einschieben der Indexierungsmittel können die Führungen leichter zueinander finden und die Montage wird vereinfacht.In a further advantageous embodiment, the fastening device has at least one first indexing means, the holding device having a second indexing means which interacts with the first indexing means during the mounting of the holding device with the fastening device. For example, the first indexing means can have an axial projection on the outer geometry of the collar of the fastening device, while the second indexing means has a groove running in the axial direction Has inner diameter of the holding device. For example, the first indexing means can consist of the extension of at least one holding means which projects beyond the outer diameter of the collar. The second indexing means can first be inserted into the first indexing means before the guides engage. By inserting the indexing means, the guides can find each other more easily and assembly is simplified.

In einer weiteren vorteilhaften Ausführungsform weist die Befestigungsvorrichtung eine erste Fixierungsgeometrie und die Haltevorrichtung eine zweite Fixierungsgeometrie auf, wobei die Fixierungsgeometrien im montierten Zustand wirkverbindbar sind. Die erste Befestigungsgeometrie weist erfindungsgemäß einen als eine erste Fixierungsgeometrie wirkenden Flansch auf und eine zweite Fixierungsgeometrie weist einen Schnapphaken an der Haltevorrichtung auf, wobei der Schnapphaken hinter dem Flansch einschnappen kann, wenn die Haltevorrichtung an der Befestigungsvorrichtung montiert ist.In a further advantageous embodiment, the fastening device has a first fixation geometry and the holding device has a second fixation geometry, the fixation geometries being operatively connectable in the assembled state. According to the invention, the first fastening geometry has a flange which acts as a first fastening geometry and a second fastening geometry has a snap hook on the holding device, the snap hook being able to snap behind the flange when the holding device is mounted on the fastening device.

Fig. 1 zeigt einen Wandring-Axial-Ventilator in konventioneller Bauform in einer dreidimensionalen Darstellung. Der Ventilator 140 wird über Haltmittel 111 in einem als Befestigungsvorrichtung 110 dienendem Wandring gehaltert. Die Befestigungsvorrichtung 110 weist einen Kragen 112 und einen Flansch 119 auf. In dem Flansch 119 sind erste Befestigungsgeometrien 115 in Form von Bohrungen vorgesehen. Der Wandring-Axial-Ventilator kann in einen ringförmigen Ausschnitt beispielsweise einer Wärmetauscherwand eingesetzt und beispielsweise mit Schrauben, die durch die ersten Befestigungsgeometrien 115 hindurchgesteckt und in der Wärmetauscherwand eingeschraubt werden, mit der Wärmetauscherwand verbunden werden. Fig. 1 shows a wall ring axial fan in a conventional design in a three-dimensional representation. The fan 140 is held in a wall ring serving as a fastening device 110 via holding means 111. The fastening device 110 has a collar 112 and a flange 119. First fastening geometries 115 in the form of bores are provided in the flange 119. The wall ring axial fan can be inserted into an annular cutout, for example of a heat exchanger wall, and can be connected to the heat exchanger wall, for example, with screws which are inserted through the first fastening geometries 115 and screwed into the heat exchanger wall.

Fig. 2 zeigt einen Wandring-Axial-Ventilator mit einem erfindungsgemäßen Befestigungssystem 100 in einer Draufsicht. Wie bei einem Wandring-Axial-Ventilator nach dem Stand der Technik wird der Ventilator 140 über Haltmittel 111 in einem als Befestigungsvorrichtung 110 dienendem Wandring gehaltert. Die Befestigungsvorrichtung 110 weist einen Kragen 112 und einen Flansch 119 auf. In dem Flansch 119 sind erste Befestigungsgeometrien 115 in Form von Bohrungen vorgesehen. Der Wandring-Axial-Ventilator kann in einen ringförmigen Ausschnitt beispielsweise einer Wärmetauscherwand eingesetzt und beispielsweise mit Schrauben, die durch die ersten Befestigungsgeometrien 115 hindurchgesteckt und in der Wärmetauscherwand eingeschraubt werden, mit der Wärmetauscherwand verbunden werden. Zusätzlich weist das Befestigungssystem 100 eine Haltevorrichtung 120 auf, die als Winkelhalter ausgeführt ist und mit deren Hilfe der Wandring-Axial-Ventilator beispielsweise an einem Bodenblech einer Wärmetauscher-Einheit befestigt werden kann. Der Wandring-Axial-Ventilator kann durch die Verwendung unterschiedlicher Haltevorrichtungen 120 an kundenspezifische Einbausituationen wie beispielsweise unterschiedliche Einbauhöhen oder unterschiedliche Befestigungspositionen angepasst werden, ohne den zugrundeliegenden Wandring-Axial-Ventilator selbst zu verändern. Die Haltevorrichtung 120 weist zwei Nuten als zweite Indizierungsmittel 122 auf, wobei die Befestigungsvorrichtung 110 erste Indixierungsmittel 113 aufweist. Diese ersten Indexierungsmittel 113 bestehen aus der Verlängerung der Haltemittel 111, die über den Außendurchmesser des Kragens 112 hinausragen. Die Nuten als zweite Indexierungsmittel 122 können zunächst in die ersten Indexierungsmittel 113 eingeschoben werden. Weiterhin weist die Befestigungsvorrichtung 110 zwei erste Führungen 117 in Form von Schwalbenschwanzführungen auf, in die korrespondiere zweite Führungen 121 an der Haltevorrichtung 120 im montierten Zustand eingeschoben sind. Bevor die Führungen 117, 121 in Eingriff kommen, befinden sich die Indizierungsmittel 113, 122 im Eingriff, wodurch die Führungen 117, 121 leichter zueinander finden und die Montage vereinfacht wird. Dabei weisen die Passungen der Indizierungsmittel 113, 122 mehr Spiel als die der Führungen 117, 121 auf. Die Führungen 117, 121 weisen Schrägen in axialer Richtung auf, wodurch sie leicht montierbar sind und trotzdem in ihrer Endstellung nach erfolgter Montage spielfrei miteinander wirkverbunden sind. Fig. 2 shows a wall ring axial fan with a fastening system 100 according to the invention in a plan view. As in the case of a wall ring axial fan according to the prior art, the fan 140 is held in a wall ring serving as a fastening device 110 via holding means 111. The fastening device 110 has a collar 112 and a flange 119. First fastening geometries 115 in the form of bores are provided in the flange 119. The wall ring axial fan can be inserted into an annular cutout, for example of a heat exchanger wall, and can be connected to the heat exchanger wall, for example, with screws which are inserted through the first fastening geometries 115 and screwed into the heat exchanger wall. In addition, the fastening system 100 has a holding device 120, which is designed as an angle holder and by means of which the wall ring axial fan can be fastened, for example, to a base plate of a heat exchanger unit. The wall ring axial fan can can be adapted to customer-specific installation situations, such as different installation heights or different fastening positions, by using different holding devices 120, without changing the underlying wall ring axial fan itself. The holding device 120 has two grooves as the second indexing means 122, the fastening device 110 having first indexing means 113. These first indexing means 113 consist of the extension of the holding means 111, which protrude beyond the outer diameter of the collar 112. The grooves as second indexing means 122 can first be inserted into the first indexing means 113. Furthermore, the fastening device 110 has two first guides 117 in the form of dovetail guides, into which corresponding second guides 121 on the holding device 120 are inserted in the assembled state. Before the guides 117, 121 come into engagement, the indexing means 113, 122 are engaged, as a result of which the guides 117, 121 find one another more easily and assembly is simplified. The fits of the indexing means 113, 122 have more play than those of the guides 117, 121. The guides 117, 121 have bevels in the axial direction, as a result of which they are easy to assemble and are nevertheless operatively connected to one another without play in their end position after assembly.

Fig. 3 zeigt einen Wandring-Axial-Ventilator mit einem Befestigungssystem, welches nicht Teil der vorliegenden Erfindung ist, in einer Seitenansicht. Haltevorrichtung 120 und Befestigungsvorrichtung 110 sind miteinander montiert und in dieser Stellung über eine Schraube 150, die durch eine Bohrung in der Befestigungsvorrichtung 110 als erste Fixierungsgeometrie in ein Sackloch in der Haltevorrichtung 120 als zweite Fixierungsgeometrie 125 eingedreht ist, miteinander fixiert. Fig. 3 shows a wall ring axial fan with a fastening system, which is not part of the present invention, in a side view. Holding device 120 and fastening device 110 are assembled with one another and fixed to one another in this position by means of a screw 150 which is screwed through a hole in the fastening device 110 as the first fixing geometry into a blind hole in the holding device 120 as the second fixing geometry 125.

Fig. 4 zeigt einen Ausschnitt aus einer Befestigungsvorrichtung eines erfindungsgemäßen Befestigungssystems 100 in einer dreidimensionalen Darstellung. In dieser Darstellung sind zwei zweite Befestigungsgeometrien 116 gut zu erkennen. Diese bestehen aus je einem axialen Hinterschnitt, auf die die Haltevorrichtung 120 aufschiebbar und somit befestigbar ist. Die zweiten Befestigungsgeometrien 116 weisen jeweils eine Schwalbenschwanzführung als erste Führung 117 auf. Weiterhin ist in dieser Darstellung der Flansch 119 der Befestigungsvorrichtung 110 zu erkennen. In dem Flansch 119 befindet sich eine erste Befestigungsgeometrie 115 in Form einer Durchgangsbohrung. Diese Bohrung dient gleichzeitig als erste Fixierungsgeometrie 118. Mit anderen Worten ist die Bohrung erste Befestigungsgeometrie 115 in dem Fall, dass der Wandring-Axial-Ventilator in konventioneller Form in einen ringförmigen Ausschnitt einer Wand eingebaut wird. In diesem Fall kann der Wandring-Axial-Ventilator mit einer Schraube, die durch diese Bohrung geführt und in die Wand eingeschraubt wird, in dem ringförmigen Ausschnitt befestigt werden. In dem Fall aber, dass der Wandring-Axial-Ventilator beispielsweise auf dem Bodenblech einer Wärmetauscher-Einheit befestigt wird, dient die selbe Bohrung als erste Fixierungsgeometrie 118, wobei durch sie eine Schraube 150 gesteckt werden kann, die in der zweiten Fixierungsgeometrie 125 der Haltevorrichtung 120 (in der Figur nicht gezeigt) verschraubt werden kann, wenn die Haltevorrichtung 120 montiert ist, um die Haltevorrichtung 120 an der Befestigungsvorrichtung 110 zu fixieren. Fig. 4 shows a detail from a fastening device of a fastening system 100 according to the invention in a three-dimensional representation. Two second fastening geometries 116 can be clearly seen in this illustration. These each consist of an axial undercut, onto which the holding device 120 can be pushed and thus fastened. The second Fastening geometries 116 each have a dovetail guide as the first guide 117. Furthermore, the flange 119 of the fastening device 110 can be seen in this illustration. A first fastening geometry 115 in the form of a through hole is located in the flange 119. This bore also serves as the first fixing geometry 118. In other words, the bore is the first fastening geometry 115 in the event that the wall ring axial fan is installed in a conventional manner in an annular cutout in a wall. In this case, the wall ring axial fan can be fastened in the ring-shaped cutout with a screw which is passed through this hole and screwed into the wall. However, in the event that the wall ring axial fan is fastened, for example, to the bottom plate of a heat exchanger unit, the same bore serves as the first fixing geometry 118, whereby a screw 150 can be inserted through it, which in the second fixing geometry 125 of the holding device 120 (not shown in the figure) can be screwed when the holding device 120 is mounted in order to fix the holding device 120 to the fastening device 110.

Fig. 5 zeigt eine Haltevorrichtung 120 eines erfindungsgemäßen Befestigungssystems 100 in einer dreidimensionalen Darstellung aus einer ersten Perspektive. Die Haltevorrichtung 120 bildet ein Kreissegment. Zwei zweite Führungen 121 in Form von Gegenstücken zu einer Schwalbenschwanzführung sind zu erkennen. Weiterhin sind zwei zweite Indizierungsmittel 122 in Form von axialen Nuten am Innendurchmesser der Haltevorrichtung 120 zu sehen. Fig. 5 shows a holding device 120 of a fastening system 100 according to the invention in a three-dimensional representation from a first perspective. The holding device 120 forms a segment of a circle. Two second guides 121 in the form of counterparts to a dovetail guide can be seen. Furthermore, two second indexing means 122 in the form of axial grooves on the inside diameter of the holding device 120 can be seen.

Fig. 6 zeigt eine Haltevorrichtung 120 eines erfindungsgemäßen Befestigungssystems 100 in einer dreidimensionalen Darstellung aus einer zweiten Perspektive. Durch die Wahl unterschiedlicher Haltevorrichtungen 120, insbesondere mit unterschiedlichen Höhen, kann auf unterschiedliche Montagesituationen reagiert werden, wobei die kundenspezifische Varianz über unterschiedliche Haltevorrichtungen 120 mit demselben Ventilator 140 abgedeckt werden kann. Fig. 6 shows a holding device 120 of a fastening system 100 according to the invention in a three-dimensional representation from a second perspective. By selecting different holding devices 120, in particular with different heights, it is possible to react to different mounting situations, wherein the customer-specific variance can be covered by different holding devices 120 with the same fan 140.

Fig. 7 zeigt einen Ausschnitt aus einer Ausführungsform eines erfindungsgemäßen Befestigungssystems 100 in einer dreidimensionalen Darstellung. Als zweite Fixierungsgeometrie 125 ist in dieser Ausführungsform ein Schnapphaken an der Haltevorrichtung 120 vorgesehen, der im montierten Zustand der Haltevorrichtung 120 an der Befestigungsvorrichtung 110 hinter den Flansch 119 der Befestigungsvorrichtung 110, der in dieser Ausführungsform als erste Fixierungsgeometrie 118 wirkt, schnappt. In dieser Ausführungsform kann damit auf eine Schraube 150 oder ein anderes Zusatzteil für die Fixierung der Haltevorrichtung 120 an der Befestigungsvorrichtung 110 verzichtet werden. Fig. 7 shows a detail from an embodiment of a fastening system 100 according to the invention in a three-dimensional representation. In this embodiment, a snap hook is provided on the holding device 120 as the second fixing geometry 125, which snaps behind the flange 119 of the fastening device 110 in the assembled state of the holding device 120, which acts as the first fixing geometry 118 in this embodiment. In this embodiment, a screw 150 or another additional part for fixing the holding device 120 to the fastening device 110 can thus be dispensed with.
