Definitions

  • the invention relates to an inlet nozzle for a radial, diagonal, or axial fan, comprising an inlet section with a circular cross-section, a radius of curvature, and a diameter that tapers in the direction of flow. Furthermore, the invention relates to a radial, diagonal, or axial fan with a corresponding inlet nozzle.
  • Axial fans and radial fans are well known in practice.
  • the JP H02 185700 A , US 2008/085186 A1 , DE 200 01 746 U1 , US 6,499,948 B1 and DE 10 2012 021 372 A1 referred to.
  • Such fans are regularly equipped with an inlet nozzle or inlet nozzle through which the fan sucks in air, which flows through an inlet opening first into the inlet area of the inlet nozzle and from there to the outlet area of the inlet nozzle.
  • an inlet nozzle In an axial-flow fan that draws air from the outside, the incoming air is guided through such an inlet nozzle.
  • This nozzle can be designed with a fluidically optimized inlet radius.
  • the inlet nozzle should direct the air flow to the rotating axial impeller with as little turbulence and loss as possible. Since there are no precise approaches to determining the geometry of an optimal inlet nozzle, the inlet radius is regularly determined experimentally, i.e., empirically, usually depending on the fan's structural parameters.
  • a reduction in the nozzle height and/or the flange dimensions without further performance losses would offer enormous advantages, namely in terms of reducing the installation space or the height of the fan.
  • the present invention is therefore based on the object of specifying an inlet nozzle for a radial, diagonal or axial fan and a radial, diagonal or axial fan with a corresponding inlet nozzle, which is suitable for avoiding, or at least reducing, the disadvantages occurring in the prior art, caused by unwanted flow separation, namely for reducing sound levels and power losses.
  • the generic inlet nozzle is characterized by a measure or a flow element on or in the curved surface of the inlet section, in particular for forcing turbulent boundary layers in the flow, which counteract/can counteract flow separation in this area.
  • a radial, diagonal, or axial fan equipped with such an inlet nozzle is characterized by the features of the independent claim 7, with the same features as the inlet nozzle according to the invention.
  • the inlet nozzle according to the invention solves a problem that predominantly occurs with inlet nozzles with small radii in the inlet section, even with an optimized inlet radius. In the prior art, it is unavoidable that, particularly with small radii, flow separation occurs in the inlet radius, leading to turbulence in the flow. This turbulence is fed to the rotating fan wheel and causes significant losses there.
  • the inlet nozzle according to the invention has a radius of curvature, so that we are referring here to an inlet nozzle "with radius.”
  • the term “radius of curvature” is to be understood in the broadest sense.
  • the "radius” can be composed of several subradii, each with a continuous or discontinuous transition between the subradii.
  • the curved inflow section has an annular recess in the sense of a zonal extension of this region, namely a region running in a ring shape in the inner surface of the inflow section, which acts in the sense of a flow element that counteracts flow separation or at least delays it.
  • two or more recesses spaced apart from each other can be provided, as required, resulting from the radius to be realized according to the desired size.
  • the recess or extension is realized as a recessed edge, the underlying idea being that a recessed edge initially separates the flow, but the main flow then reattaches to the offset geometry. This is achieved by a vortex that literally sucks in the main flow in the separation area (source: Nitsche, W.: Flow Measurement Technology, Springer-Verlag 1994 (geometrically induced separation)).
  • the widening in the radius of the inflow section is designed as an outwardly recessed edge. Accordingly, the edge is formed by two bends or chamfer angles, namely the chamfer angles ⁇ and ⁇ with the rule 180° ⁇ ⁇ ⁇ 270° and 180° > ⁇ > 90°. Particularly favorable flow conditions arise in this area.
  • the inlet nozzle can be made entirely of plastic. In a simple design, it is advisable to manufacture the inlet nozzle from metal, in particular from sheet metal, using conventional manufacturing processes for producing sheet metal parts.
  • the extension or the annular recess can be greater than the wall thickness of the sheet metal to ensure sufficient stability. Furthermore, it is advantageous if the length of the recess is greater than the depth of the recess, namely to favor the flow conditions in such a way that the separation area for the flow defined immediately after the recess is in a suitable ratio to the length of the recess and the reattachment point of the flow.
  • the recess can be generated, for example, by deep drawing or embossing the sheet metal.
  • Fig. 1 shows a schematic sectional view of an embodiment of a conventional inlet nozzle 1 with radius Ra.
  • the inlet nozzle 1 comprises a fastening flange 2 and an inlet section 3 with a curved surface 5, wherein the radius Ra has a very special effect on the inflowing air 4.
  • Fig. 2 shows in perspective view an inlet nozzle 1 with radius Ra known from the prior art, wherein the inlet section 3 with curved surface 5 and the fastening flange 2 can be seen.
  • Fig. 3 shows in a lower illustration, partially, the profile of the inlet nozzle 1 according to the invention in the area of the radius Ra, ie the inlet section 3 with the curved surface 5 on the inside of the inlet nozzle 1. It can be seen that a measure influencing the flow is provided there, namely a recess 6, which is designed as a recessed, circumferential edge.
  • the detailed view above shows the inflow section 3 and the recess 6, whose depth is smaller than the length or width in the flow direction 7 of the incoming air.
  • the recess 6 can cause turbulent boundary layers in the flow with respect to the incoming air, which counteract the problematic flow separation and thus noise generation and power loss.
  • Fig. 5 shows that in Fig. 4 marked detail X with corresponding labeling, from which the dimensions/limits result.
  • the angles ⁇ and ⁇ are shown again enlarged, showing that the extension is designed as a recessed edge (6) with chamfer angles of 180° ⁇ ⁇ ⁇ 270° and 180° > ⁇ > 90°.
  • Fig. 6 Finally, a comparison shows the profile of two conventional inlet nozzles 1 in the area of the inlet section 3 with different radii Ra, with the inflow being indicated by an arrow 7 symbolizing the flowing air.
  • Variant b) is designed with a smaller radius and thus leads to power losses and increased noise levels.
  • Variant c) shows the inventive inlet nozzle 1 with the previously discussed recess 6 in the area of the curved surface 5, which produces the effect according to the invention, and this with the simplest design and manufacture.
