Description

Die Erfindung betrifft einen Gegenstand nach dem Oberbegriff von Anspruch 1.The invention relates to an object according to the preamble of claim 1.

Durchlässe, wie beispielsweise Dralldurchlässe, weisen üblicherweise feststehende Lamellen auf, wobei zwei benachbarte Lamellen zwischen sich eine Auslassöffnung bilden. Die anströmseitige Kante und die abströmseitige Kante jeder Lamelle sind geradlinig ausgebildet. Da derartige Lamellen insoweit eine gerade Abrisskante aufweisen, kommt es zu einer starken Wirbelbildung, was wiederum zu einem höheren Druckverlust sowie einer unerwünschten Geräuschbildung führt. Aus der DE 10 2007 016 184 A1 ist eine Klappenanordnung, insbesondere für ein Kraftfahrzeug-Belüftungssystem, bekannt.Passages, such as swirl diffusers, usually have fixed fins, with two adjacent fins forming an outlet opening between them. The upstream edge and the downstream edge of each lamella are straight. Since such lamellae have a straight tear-off edge to this extent, there is a strong eddy formation, which in turn leads to a higher pressure loss and undesirable noise formation. From the DE 10 2007 016 184 A1 a flap arrangement, in particular for a motor vehicle ventilation system, is known.

Aufgabe der Erfindung ist es, die vorgenannten Nachteile zu vermeiden und eine Einrichtung zur Beeinflussung einer Luftströmung anzugeben, deren Geräuschentwicklung geringer ist.The object of the invention is to avoid the aforementioned disadvantages and to provide a device for influencing an air flow, the noise of which is lower.

Diese Aufgabe wird gelöst, durch die kennzeichnenden Merkmale von Anspruch 1. Aufgrund der aus Vorsprüngen und Vertiefungen bestehenden Außenkontur weist die erfindungsgemäße Einrichtung damit keine gerade Abrisskante mehr auf. Vielmehr entstehen viele versetzt zueinander angeordnete kurze Abrisskanten. Damit können sich lediglich entsprechend kleine Wirbel bilden, die sich teilweise sogar gegenseitig aufheben. Damit wird die unerwünschte Geräuschbildung reduziert.This object is achieved by the characterizing features of claim 1. Because of the projections and depressions Existing outer contour, the device according to the invention thus no longer has a straight tear-off edge. Rather, there are many short tear-off edges arranged offset from one another. This means that only correspondingly small vortices can form, which can even partially cancel each other out. This reduces unwanted noise.

Die Form und die Abmessungen wenigstens eines Vorsprungs und zumindest einer Vertiefung können gleich sein. Es ist aber auch selbstverständlich möglich, dass zumindest eine Vertiefung eine andere Ausgestaltung als ein Vorsprung aufweisen. So kann beispielsweise der Vorsprung dreieckförmig ausgebildet sein, während die Vertiefung in ihrem tiefsten Bereich flach ausgebildet ist.The shape and dimensions of at least one protrusion and at least one recess can be the same. However, it is of course also possible for at least one depression to have a configuration other than a projection. For example, the projection can be triangular, while the deepest area of the depression is flat.

Die Vorsprünge sowie die Vertiefungen zumindest einer Kante, insbesondere zumindest einer abströmseitigen Kante, können einen wellenförmigen Verlauf aufweisen.The projections and the depressions of at least one edge, in particular at least one downstream edge, can have a wavy course.

Die Vorsprünge sowie die Vertiefungen zumindest einer Kante, insbesondere zumindest einer abströmseitigen Kante, können einen zick-zack-förmigen Verlauf aufweisen. Bei einer solchen Ausgestaltung sind sowohl die Vorsprünge als auch die Vertiefungen in etwa dreieckförmig ausgebildet.The projections and the depressions of at least one edge, in particular at least one downstream edge, can have a zigzag shape. In such an embodiment, both the projections and the depressions are approximately triangular.

Die Vorsprünge sowie die Vertiefungen zumindest einer Kante, insbesondere zumindest einer abströmseitigen Kante, können einen rechteckförmigen Verlauf aufweisen. Bei einer solchen Ausgestaltung ist die entsprechende Kante nach Art eines Rakels ausgebildet.The projections and the depressions of at least one edge, in particular at least one downstream edge, can have a rectangular shape. In such an embodiment, the corresponding edge is designed in the manner of a doctor blade.

Die Vorsprünge zumindest einer Kante, insbesondere zumindest einer abströmseitigen Kante, weisen eine einheitliche absolute Ausrichtung auf. Damit weisen die Vorsprünge und/oder die Vertiefungen eine einheitliche Ausrichtung unabhängig von dem tatsächlichen Verlauf der betreffenden Kante auf. Handelt es sich bei der Einrichtung beispielsweise um ein Lamellenblatt mit einer runden Kante, können alle Vorsprünge beispielsweise in Strömungsrichtung weisen. Bei einer solchen runden Ausgestaltung weisen die Vorsprünge untereinander dann über den Verlauf der Kante gesehen eine unterschiedliche Ausgestaltung auf.The projections of at least one edge, in particular at least one downstream edge, have a uniform one absolute focus on. The projections and / or the depressions thus have a uniform orientation regardless of the actual course of the edge in question. If the device is, for example, a lamella sheet with a round edge, all the projections can point, for example, in the direction of flow. In such a round design, the projections have a different design from one another when viewed over the course of the edge.

Es ist aber auch durchaus möglich, dass die Vorsprünge zumindest einer Kante, insbesondere zumindest einer abströmseitigen Kante, eine relative, auf einen Punkt gerichtete Ausrichtung aufweisen. Auch hier ist die Ausrichtung der Vorsprünge unabhängig von dem Verlauf der betreffenden Kante. Alle Vorsprünge können beispielsweise auf einen Mittelpunkt oder aber auf die Symmetrieachse gerichtet sein. Auch bei einer solchen Ausführungsfrom weisen die Vorsprünge der betreffenden Kante eine andere Ausgestaltung auf.However, it is also entirely possible that the projections of at least one edge, in particular at least one downstream edge, have a relative orientation directed towards a point. Here too, the alignment of the projections is independent of the course of the edge in question. All projections can be directed, for example, to a center point or to the axis of symmetry. Even with such an embodiment, the projections of the edge in question have a different configuration.

Die Einrichtung ist als Lamelle, nämlich als feststehende Lamelle, eines Durchlasses, insbesondere eines Dralldurchlasses, ausgebildet. Bei einem solchen Durchlass kann es sich um einen Auslass oder einen Einlass handeln.The device is designed as a lamella, namely as a fixed lamella, of a passage, in particular a swirl passage. Such a passage can be an outlet or an inlet.

Zur weiteren Reduzierung von Geräuschen kann zumindest eine Vertiefung und/oder ein Vorsprung quer zum Verlauf der gesamten Kante abgerundet ausgebildet sein.To further reduce noise, at least one depression and / or a projection can be rounded off transversely to the course of the entire edge.

Die Höhe H zumindest eines Vorsprungs beträgt zum tiefsten Punkt der benachbarten Vertiefung gesehen zwischen 0,5 mm und 10 mm, vorzugsweise zwischen 1 mm und 5 mm. Die Höhe H bezieht sich auf den Abstand vom höchsten Punkt des Vorsprungs bis zum tiefsten Punkt der benachbarten Vertiefung.The height H of at least one projection is between 0.5 mm and 10 mm, preferably between 1 mm and 5 mm, seen at the lowest point of the adjacent depression. The height H refers to the distance from the highest point of the projection to the lowest point of the neighboring depression.

Die Breite B zumindest eines Vorsprungs beträgt zwischen 1 mm und 8 mm, vorzugsweise zwischen 2 mm und 4 mm. Die Breite B bezieht sich auf den Abstand der Scheitelpunkte zweier benachbarter Vorsprünge bzw. den Mittenabstand zweier benachbarter Vorsprünge.The width B of at least one projection is between 1 mm and 8 mm, preferably between 2 mm and 4 mm. The width B relates to the distance between the vertices of two adjacent projections or the center distance of two adjacent projections.

Vorzugweise sind 10 bis 50 Vorsprünge pro 100 mm Länge an Kante vorgesehen. Handelt es sich bei der Einrichtung um eine Lamelle eines Durchlasses, bieten sich 20 bis 30 Vorsprünge pro 100 mm Länge an Kante an. Bei Ausgestaltung der Einrichtung als Klappenblatt sind vorzugsweise 25 bis 40 Vorsprünge pro 100 mm Länge an Kante vorteilhaft.10 to 50 projections per 100 mm length are preferably provided on the edge. If the device is a lamella of an opening, 20 to 30 projections per 100 mm length on the edge are recommended. When designing the device as a flap leaf, preferably 25 to 40 projections per 100 mm length on the edge are advantageous.

Die Abmessungen der Vorsprünge können über den Verlauf einer Kante variieren, vorzugsweise bei Durchlässen, oder stetig, vorzugsweise bei Klappen, sein.The dimensions of the projections can vary over the course of an edge, preferably in the case of passages, or continuously, preferably in the case of flaps.

In allen Figuren werden für gleiche bzw. gleichartige Bauteile übereinstimmende Bezugszeichen verwendet. Die Figuren 4 bis 12 zeigen keine Ausgestaltung der erfindungsgemäßen Komponente.Corresponding reference numerals are used in all figures for identical or similar components. The Figures 4 to 12 do not show any configuration of the component according to the invention.

In Fig. 1 ist ein Dralldurchlass 1 dargestellt, der als Einrichtungen 2 zur Beeinflussung einer Luftströmung (Pfeil 3) geschwungen ausgebildete Lamellen aufweist. Zwischen zwei benachbarten Lamellen sind Auslassöffnungen 4 vorgesehen, durch die die Luft in Richtung des Pfeils 3 in den zu belüftenden Raum strömt. Jede Lamelle besteht aus einem Flächenelement mit einer anströmseitigen Kante 5 und mit einer abströmseitigen Kante 6.In Fig. 1 A swirl passage 1 is shown, which has curved lamellae as devices 2 for influencing an air flow (arrow 3). Outlet openings 4 are provided between two adjacent slats, through which the air flows in the direction of arrow 3 into the room to be ventilated. Each lamella consists of a surface element with an upstream edge 5 and with an outflow edge 6.

Wie insbesondere den Fig. 2 und 3 zu entnehmen ist, ist die anströmseitige Kante 5 jeder Lamelle geradlinig ausgebildet.Like the one in particular Fig. 2 and 3 can be seen, the upstream edge 5 of each slat is rectilinear.

Demgegenüber weist die abströmseitige Kante 6 eine mit vorstehenden Vorsprüngen 7 und dazwischen liegenden Vertiefungen 8 versehene Außenkontur auf. In dem dargestellten Ausführungsbeispiel weist die abströmseitige Kante 6 einen in etwa wellenförmigen Verlauf auf.In contrast, the downstream edge 6 has an outer contour provided with protruding projections 7 and recesses 8 lying between them. In the illustrated embodiment, the downstream edge 6 has an approximately undulating course.

Die strömende Luft ist durch die Pfeile 3 dargestellt. Infolge des wellenförmigen Verlaufs der abströmseitigen Kante 6 hat die Kante keine geradlinige Abrisskante. Damit bilden sich allenfalls kleine Wirbelwalzen, die sich teilweise sogar selbst gegeneinander aufheben. Die Vertiefungen 8 und Vorsprünge 7 können selbstverständlich quer zum Verlauf der gesamten Kante abgerundet sein.The flowing air is represented by the arrows 3. As a result of the undulating course of the edge 6 on the outflow side, the edge has no straight-line tear-off edge. At most, small swirl rollers are formed, which sometimes even cancel each other out. The depressions 8 and projections 7 can of course be rounded transversely to the course of the entire edge.

In Fig. 4 ist ein Luftleitelement mit insgesamt drei Einrichtungen 2 zur Beeinflussung einer Luftströmung in einer Komponente einer klimatechnischen Anlage dargestellt. Bei einer solchen Komponente handelt es sich in dem vorliegenden Fall um einen Schlitzdurchlass. Das Luftleitelement ist drehbar um die Achse R in dem nicht dargestellten Schlitzdurchlass gelagert. Wie Fig. 4 zu entnehmen ist, sind die abströmseitigen Kanten 6 mit vorstehenden Vorsprüngen 7 und dazwischen liegenden Vertiefungen 8 versehen, wobei die Vorsprünge 7 sowie die Vertiefungen 8 einen zick-zack-förmigen Verlauf aufweisen.In Fig. 4 is an air guide element with a total of three devices 2 for influencing an air flow in one Component of an air conditioning system shown. In the present case, such a component is a slot passage. The air guide element is rotatably mounted about the axis R in the slot passage, not shown. How Fig. 4 It can be seen that the downstream edges 6 are provided with protruding projections 7 and recesses 8 lying between them, the projections 7 and the recesses 8 having a zigzag shape.

In den Fig. 5 bis 12 sind Regler dargestellt, wobei als Einrichtung 2 in jedem Regler ein Klappenblatt vorgesehen ist. Die Fig. 5 bis 8 betreffen einen rechteckigen und die Fig. 9 bis 12 einen runden Regler. Jedes Klappenblatt ist um eine quer zur Strömungsrichtung 3 ausgerichtete Achse D drehbar in dem Regler gelagert.In the 5 to 12 controllers are shown, with a damper blade being provided as device 2 in each controller. The 5 to 8 concern a rectangular and the 9 to 12 a round regulator. Each damper blade is rotatably mounted in the controller about an axis D oriented transversely to the flow direction 3.

Bei den Ausführungsbeispielen nach den Fig. 5 und 9 weist lediglich die abströmseitige Kante 6 eine mit vorstehenden Vorsprüngen 7 und dazwischen liegenden Vertiefungen 8 versehene Außenkontur auf. Die anströmseitige Kante 5 ist geradlinig ausgebildet.In the embodiments according to the Fig. 5 and 9 only the outflow-side edge 6 has an outer contour provided with protruding projections 7 and recesses 8 lying between them. The upstream edge 5 is rectilinear.

Bei den Ausführungsbeispielen nach den Fig. 7 und 11 weisen sowohl die anströmseitige Kante 5 als auch die abströmseitige Kante 6 Vorsprünge 7 und dazwischen liegende Vertiefungen 8 auf.In the embodiments according to the Fig. 7 and 11 Both the upstream edge 5 and the downstream edge 6 have projections 7 and recesses 8 lying between them.

Wie den Fig. 6 und 8 zu entnehmen ist, weisen die Vorsprünge 7 sowie die Vertiefungen 8 einen in etwa zick-zack-förmigen Verlauf auf, wobei die Form und die Abmessungen der Vorsprünge 7 und der Vertiefungen 8 gleich sind.Like that Fig. 6 and 8th can be seen, the projections 7 and the depressions 8 have an approximately zigzag-shaped course, the shape and dimensions of the projections 7 and the depressions 8 being the same.

Bei den runden Ausführungsformen der Klappenblätter nach den Fig. 10 und 12 sind die Form und die Abmessungen der Vorsprünge 7 und der Vertiefungen 8 nicht gleich. So weisen die Vorsprünge 7 eine einheitliche absolute Ausrichtung auf, wobei in dem dargestellten Ausführungsbeispiel die Ausrichtung parallel zur Strömungsrichtung (Pfeil 3) ist.In the round embodiments of the damper blades according to the Fig. 10 and 12 the shape and dimensions of the projections 7 and the recesses 8 are not the same. The projections 7 thus have a uniform absolute alignment, the alignment being parallel to the direction of flow (arrow 3) in the exemplary embodiment shown.

Infolge dessen vergrößert sich die Höhe der Vorsprünge 7 von der Mitte M jeder Kante zu den beiden Achsstummeln 9 hin, die zur Lagerung vorgesehen sind.As a result, the height of the projections 7 increases from the center M of each edge to the two stub axles 9 which are provided for storage.

In den Fig. 6, 8 und 10 ist beispielshaft die Höhe H der Vorsprünge 7, die zum tiefsten Punkt der benachbarten Vertiefung 8 gesehen zwischen 0,5 mm und 10 mm, beträgt, eingezeichnet. Die Höhe H bezieht sich auf den Abstand vom höchsten Punkt eines Vorsprungs 7 bis zum tiefsten Punkt der benachbarten Vertiefung 8.In the Fig. 6 . 8th and 10 the height H of the projections 7, which is between 0.5 mm and 10 mm at the lowest point of the adjacent recess 8, is shown as an example. The height H relates to the distance from the highest point of a projection 7 to the lowest point of the adjacent depression 8.

Auch ist in den Fig. 6, 8 und 10 beispielshaft die Breite B eines Vorsprungs 7, die zwischen 1 mm und 8 mm beträgt, eingezeichnet. Die Breite B bezieht sich auf den Abstand der Scheitelpunkte zweier benachbarter Vorsprünge 7 bzw. den Mittenabstand zweier benachbarter Vorsprünge 7.Is also in the Fig. 6 . 8th and 10 for example, the width B of a projection 7, which is between 1 mm and 8 mm. The width B relates to the distance between the vertices of two adjacent projections 7 or the center distance between two adjacent projections 7.

Handelt es sich bei der Einrichtung 2 um eine Lamelle eines Durchlasses (beispielsweise Fig. 1), bieten sich 20 bis 30 Vorsprünge pro 100 mm Länge an Kante 5, 6 an. Bei Ausgestaltung der Einrichtung 2 als Klappenblatt eines Reglers ((beispielsweise Fig. 5) sind vorzugsweise 25 bis 40 Vorsprünge pro 100 mm Länge an Kante 5, 6 vorteilhaft.If the device 2 is a lamella of a passage (for example Fig. 1 ), there are 20 to 30 projections per 100 mm length on edge 5, 6. When designing the device 2 as a damper blade of a controller ((for example Fig. 5 ) 25 to 40 projections per 100 mm length on edge 5, 6 are preferably advantageous.

Die Abmessungen der Vorsprünge 7 variieren bei dem Ausführungsbeispiel beispielsweise nach Fig. 10 über den Verlauf der Kante 6, während die Abmessungen der Vorsprünge 7 bei dem Ausführungsbeispiel beispielsweise nach Fig. 8 über den Verlauf der jeweiligen Kante 5, 6 stetig sind.The dimensions of the projections 7 vary in the exemplary embodiment, for example Fig. 10 over the course the edge 6, while the dimensions of the projections 7 according to the embodiment, for example Fig. 8 are continuous over the course of the respective edge 5, 6.
