Definitions

  • the invention relates to a radial fan with backward inclined vanes.
  • radial fan wheels or Radial impellers are used e.g. in air conditioning and ventilation technology used.
  • forwardly inclined wheels with 30 - 40 vanes which run from inside to outside in the running direction, are used in ventilation technology with diameters of 160 up to 400 mm in conjunction with flow-forming volute casings used. Their static efficiency is included about 30 to 35%.
  • Such an impeller is from the JP 06299993 known.
  • An embodiment as a radial fan with converging exit ring shows US 1,447,915, in which the centrifugally accelerated air through the radial outwardly converging outlet nozzle in addition is accelerated.
  • EP 0 848 788 shows an impeller in which the outer edges the blades have a sloping, inclined to the axis of rotation Edge and the peripheral end portions of the end plates are curved to the sound pressure in a frequency range from 50 to 300 Hz lower.
  • the object of the present invention is a To create a fan wheel that is from the state of the art known disadvantages are at least partially eliminated.
  • the developments according to claim 2 relate to the diameter ranges, in which the effect occurs the most.
  • the embodiments according to claim 3 and 4 give Opening angle at which the desired air flow entry (claim 3) and a particularly effective diffusion effect is achieved (claim 4).
  • the claims 5 and 6 relate to developments in which the fan is designed to be advantageous in the area of the air inlet.
  • the fan shown in Fig. 1 consists of a flat Bottom plate 1, one of a plurality of vanes. 2 existing blade ring and a cover disc 3.
  • Bodenund Cover disk 1, 3 are concentric at a distance B arranged with respect to the axis of rotation 4 and are connected to each other via the blade ring.
  • the cover disk 3 has an inlet opening 5 with the diameter DE, through which sucked a flow medium during operation becomes.
  • the cover plate 3 extends from a the inlet opening 5 limiting frontal edge 6 starting Trumpet-shaped widened inwardly and radially in one outer edge region 7.
  • the bottom plate 1 is as Circular disk is formed and carries a centrally arranged Hub assembly 9 with an opening 10, which with a Drive unit can be connected to the fan to drive (Fig. 6).
  • Bottom plate and drive flange can also be made in one piece be educated.
  • Bottom and cover discs are radial through their outer edges 8 are limited and are over the blade ring at a distance B connected to each other (drive with external rotor motor).
  • the blade ring consists of seven vanes 2, the evenly arranged in a star shape with respect to the axis of rotation 4 are.
  • the real thing Guide vane extends from the inner edge eleventh starting radially and inclined towards the direction R. to the outside, where it ends at the vane outer edge 12 (Fig. 3).
  • the extending in the axial direction Guide vanes curved with respect to the axis of rotation 4, wherein the convex sides facing outwards.
  • Fan wheel is also referred to as a backward curved impeller, they are in alternative (not shown) Versions usually equipped with 6 - 14 blades, while the vanes 2 also designed flat his.
  • Your margins are suitable with the bottom and the cover plate 1, 3 connected, wherein the Contours of the margins in their terminal area respectively the curvature of the bottom 1 and the cover plate. 3 consequences.
  • Outer and inner edge 12, 11, extend substantially parallel to the axis of rotation 4, wherein in the illustrated Embodiment, the inner edge 11 in the connection area to the cover plate of production and fluidic Reasons curved runs.
  • Bottom and cover plate 1, 3 have an outer diameter DN, which is above the blade outer diameter DSa, so that between the outer edge 8 of the bottom plate 1 and the outer diameter Leitschaufel DSa an outer edge region 14 is defined.
  • the distance between deck and bottom disk 3, 1 or the blade width B is maximum: 5 (DN-DSA) / 2
  • the fan In operation, the fan is in the drive direction R ( Figure 3), and the vanes convey that inside the fan impeller flow fluid to the outside, where it is at Schaufelradaußen mailmesser DSa substantially radial outlet. Due to the negative pressure caused Inside the impeller, fluid is introduced from outside through the inlet 5 sucked.
  • the flow direction runs ie coaxially through the inlet opening 5 in the interior of the impeller and is guided radially outward, wherein the flow cross section is constantly expanding.
  • the flow initially leaves the diameter DSa the blade interspaces 15 into a diffusion space 16, the annular between the outer edges 12 of the vanes 2, the outer edge regions 7, 14 of the cover or the bottom plate 3, 1, and the outer diameter DN of the corresponding outer edges 8 is defined.
  • FIGS. 4 and 5 define a Diffusion space 16, whose cross section in contrast to in Fig. 2 shown rectangular shape trapezoidal outward is widened.
  • the outer edge region 7 open the cover disc 3 to the outside by an angle ⁇ , which is in a range between 0 and 35 °.
  • This additional Expansion increases the diffusion effect and allows the outer edge regions 7, 14 narrower shape, so that the outer diameter DN, for example only 20% or less above the blade outer diameter DSa must lie, but he should at least 8% over it lie.
  • Fig. 5 shows a corresponding expansion of both outer Edge regions 7, 14 of the bottom and cover plate 1, 3. Die Edge widening can also be performed only on the bottom plate 1 be (not shown).
  • Fig. 6 shows a complete unit, in addition to the one described above Fan additionally with a suction plate 17 integrated inlet nozzle 18, which has brackets 19 and carrier 20 connected to a motor bracket 21 is, in turn, carries a motor 22 whose drive shaft 23 coupled to the hub assembly 9 of the fan wheel is.
  • Such complete units are ü. A. in so-called climate boxes (not shown) used in which built up a pressure on the fan unit inside which is in one or more outgoing channels volume flows generated.
  • air conditioning boxes usually are not designed flow dynamic, is the specified Diffusion effect here particularly effective, since on additional flow-conducting or sound-insulating measures can largely be dispensed with.
  • missing radially adjacent to the diffusion space 16 adjacent guide elements like stationary diffusion rings.
  • fan wheels are in the following range: Outside diameter DN 200 - 1800 mm Blade outer diameter DSa 160 - 1400 mm Shovel inner diameter DSi 100 - 650 mm Blade width at the exit B 40 - 280 mm Inlet opening diameter DE 98 - 660 mm
