Definitions

  • the invention relates to a device for influencing an air flow in a component of an air-conditioning system, wherein the device comprises a surface element with at least one upstream and at least one downstream edge and wherein the surface element is arranged either stationary in the component or one parallel to the general extent the axis of the surface element or for the general extension of a portion of the plane of the surface element aligned axis is rotatably mounted in the component.
  • Passages such as swirl diffusers, usually have fixed fins, with two adjacent fins form an outlet opening between them.
  • the upstream edge and the downstream edge of each blade are formed in a straight line. Since such slats so far have a straight spoiler edge, there is a strong vortex formation, which in turn leads to a higher pressure loss and unwanted noise.
  • the object of the invention is to avoid the aforementioned disadvantages and to provide a device for influencing an air flow whose noise is lower.
  • At least one edge in particular at least one downstream edge, has an outer contour provided with projecting projections and recesses therebetween. Due to the outer contour consisting of projections and recesses, the device according to the invention thus no longer has a straight spoiler edge. Rather, many offset staggered edges are arranged offset from one another. This can only form correspondingly small vortices, which sometimes even cancel each other out. This reduces unwanted noise.
  • At least one projection and at least one recess may be the same. However, it is of course also possible that at least one recess have a different configuration than a projection.
  • the projection may be triangular, while the recess is formed flat in its deepest region.
  • the projections and the recesses of at least one edge may have a wave-shaped course.
  • the projections and the recesses of at least one edge may have a zigzag-shaped course.
  • both the projections and the depressions are formed approximately triangular.
  • the projections and the depressions of at least one edge can have a rectangular profile.
  • the corresponding edge is formed in the manner of a doctor blade.
  • the projections of at least one edge may have a uniform absolute orientation.
  • the projections and / or the recesses have a uniform orientation regardless of the actual course of the relevant edge. If the device is, for example, a lamellar blade with a round edge, all projections can face, for example, in the direction of flow. In such a round configuration, the projections then have a different configuration with respect to each other over the course of the edge.
  • the projections have at least one edge, in particular at least one downstream edge, a relative, directed to a point orientation. Again, the orientation of the projections is independent of the course of the relevant edge. All projections may be directed, for example, to a center or to the axis of symmetry. Even with such a regardssfrom have the projections of the respective edge on another embodiment.
  • the device can be designed as a damper blade.
  • a corresponding damper blade can be used for example in a fire damper, a volumetric flow controller, a throttle valve or the like.
  • a throttle valve When using the blade in a throttle valve remains the position of the damper blade unchanged.
  • the position of the damper blade changes, for example in a volumetric flow controller with changing air flow within the air conditioning system.
  • the device can also be designed as a lamella, in particular as a fixed lamella, of a passage, in particular of a swirl passage.
  • a passage may be an outlet or an inlet.
  • At least one recess and / or a projection can be formed rounded transversely to the course of the entire edge.
  • the height H of at least one projection is, seen at the lowest point of the adjacent recess, between 0.5 mm and 10 mm, preferably between 1 mm and 5 mm.
  • the height H refers to the distance from the highest point of the projection to the lowest point of the adjacent recess.
  • 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 refers to the distance between the vertices of two adjacent protrusions and the center distance of two adjacent protrusions.
  • the device is a louver of a passage, 20 to 30 projections per 100 mm of length are available at the edge. In the embodiment of the device as a damper blade are preferably 25 to 40 projections per 100 mm length at edge advantageous.
  • the dimensions of the projections may vary over the course of an edge, preferably in the case of passages, or continuously, preferably in the case of flaps.
  • a swirl diffuser 1 which has curved lamellae as devices 2 for influencing an air flow (arrow 3). Between two adjacent slats outlet openings 4 are provided, through which the air flows in the direction of the arrow 3 in the space to be ventilated.
  • Each lamella consists of a surface element with an upstream edge 5 and with a downstream edge 6.
  • the inflow-side edge 5 of each blade is formed in a straight line.
  • downstream edge 6 has an outer contour provided with projecting projections 7 and recesses 8 located therebetween. In the illustrated embodiment, the downstream edge 6 has an approximately wave-shaped course.
  • the flowing air is shown by the arrows 3.
  • the edge has no rectilinear tear-off edge. This form at most small vortex rolls, which sometimes even cancel each other.
  • the recesses 8 and projections 7 may of course be rounded transversely to the course of the entire edge.
  • 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.
  • a component is a slot passage in the present case.
  • the air guide is rotatably mounted about the axis R in the slot passage, not shown.
  • the downstream edges 6 are provided with protruding projections 7 and recesses 8 located therebetween, wherein the projections 7 and the recesses 8 have a zigzag-shaped course.
  • each damper blade is provided in the Fig. 5 to 12 regulators, wherein as device 2 in each regulator a damper blade is provided.
  • the Fig. 5 to 8 affect a rectangular and the Fig. 9 to 12 a round knob.
  • Each damper blade is rotatably mounted in the controller about an axis D oriented transversely to the flow direction 3.
  • the downstream edge 6 has an outer contour provided with protruding projections 7 and recesses 8 located therebetween.
  • the upstream edge 5 is rectilinear.
  • Both the inflow-side edge 5 and the outflow-side edge 6 have protrusions 7 and recesses 8 located therebetween.
  • the projections 7 and the recesses 8 in an approximately zigzag-shaped course, the shape and dimensions of the projections 7 and the recesses 8 are the same.
  • the shape and dimensions of the projections 7 and the recesses 8 are not equal.
  • the projections 7 have a uniform absolute orientation, wherein in the illustrated embodiment, the orientation is parallel to the flow direction (arrow 3).
  • the height of the projections 7 increases from the center M of each edge to the two stub shafts 9, which are provided for storage.
  • the height H refers to the distance from the highest point of a projection 7 to the lowest point of the adjacent recess 8.
  • the width B refers to the distance between the vertices of two adjacent projections 7 and the center distance of two adjacent projections. 7
  • the device 2 is a louver of a passage (for example Fig. 1 ), 20 to 30 projections per 100 mm in length at edge 5, 6 offer.
  • the device 2 as a damper blade of a controller ((for example Fig. 5 ) are preferably 25 to 40 protrusions per 100 mm in length at edge 5, 6 advantageous.
  • the dimensions of the projections 7 vary in the embodiment, for example Fig. 10 over the course the edge 6, while the dimensions of the projections 7 in the embodiment, for example after Fig. 8 are continuous over the course of the respective edge 5, 6.
