Definitions

  • the invention relates to an axial fan for conveying cooling air in particular for an internal combustion engine of a motor vehicle according to the preamble of patent claim 1.
  • a generic axial fan is in the earlier patent application of the applicant with the official file number DE 10 2010 042 325.4 disclosed.
  • the axial fan has attached to a hub ring fan blades on their pressure side a hub ramp and on its suction side air guide elements, also called stabilizers, which serve to influence the fan flow have.
  • the fan blades each have a leading edge, also called the leading edge, and a trailing edge, also called the trailing edge.
  • the trailing edge of the fan blade has substantially two radially extending portions, namely an outer portion located outside the hub ramp and an inner portion disposed within the hub ramp.
  • the inner portion of the trailing edge is inwardly for weight-saving reasons, ie angled in the direction of the hub ring, so that there is a groove for the trailing edge and thus a reduction in the width of the fan blade. It has been found that as a result of this groove of the trailing edge a transverse and / or backflow the fan blade flow results, which produces an unfavorable influence on the flow on the pressure side of the adjacent fan blade. As a result of this return and / or transverse flow, a vortex structure results in the region of the hub ramp, which results in a drop in the efficiency.
  • An axial fan with fan blades was known, on whose suction side air guide elements and on the pressure side hub ramps are arranged. As a result, a flow channel is formed, which causes a stable guidance of the flow in the region of the blade root.
  • An axial fan with the features of the first part of claim 1 is further from the document DE 601 28 435 T2 known. It is an object of the present invention to improve the flow conditions in an axial fan of the type mentioned and in particular to avoid lossy vortex formation.
  • the fan blade has a trailing edge with two sections, wherein a first outer section is located radially outside the hub ramp and a second inner section is located radially inside the hub ramp. According to the invention, it is advantageous if the trailing edge in the outer region radially outwardly of the hub ramp identifies a course which continues substantially unchanged beyond the radial position of the hub ramp radially inward into the inner region and runs in the radially innermost region towards the hub.
  • the inventive Success is achieved in that a stabilization of the fan blade flow in the hub ramp area is achieved, ie, a transverse and / or reverse flow around the trailing edge of the fan blade is at least reduced or prevented.
  • a stabilization of the fan blade flow in the hub ramp area is achieved, ie, a transverse and / or reverse flow around the trailing edge of the fan blade is at least reduced or prevented.
  • the radially innermost region is the radially inner part of the radius of the radially inner region.
  • this proportion is about a third, about a quarter or preferably less than about one fifth of the radius of the inner region of the trailing edge.
  • the fan blade advantageously also has substantially the same blade depth in the inner region as in the outer region, ie in particular that the blade trailing edge transitions from the outer portion substantially rectilinearly into the inner portion, so that the overall result is a straight trailing edge up to the blade root area. It does not harm a certain curvature of the leading edge, which in this consideration of simplicity half as a straight line, with an odd curved leading edge would also be permissible.
  • the blade depth and also the blade width in the area within the hub ramp are thus advantageously increased.
  • fan blade and fan blade are used in the context of the present application as synonyms.
  • blade depth is understood to mean the axial extent of the fan blade.
  • the sheet depth is the projection of the sheet width in the circumferential direction, wherein the sheet width is the distance between the sheet leading edge and sheet trailing edge measured in the direction of the chord.
  • the trailing edge is rounded in the innermost region. As a result, a voltage-reduced transition of the blade trailing edge is made possible in the hub area.
  • the leaf trailing edge merges in its innermost region-via a rounding-into the free edge of the hub ramp. This achieves an increase in the strength in the blade root area for the connection of the fan blade to the hub.
  • stabilizers are arranged on the suction side of the fan blades, which are preferably located radially within the hub ramp. The downstream region of the stabilizer thus opens into the inner portion of the blade trailing edge.
  • the stabilizers in conjunction with the hub ramps between two blades achieved a further stabilization of the flow in the Schaufelfuß Symposium.
  • the hub is designed as a hub ring, which has a substantially smaller axial extent than the fan blades.
  • a cylindrical hub in the classical sense is therefore no longer available.
  • the axial extent of the fan blades is - as mentioned above - referred to as blade depth, which represents a projection of the blade width in the circumferential direction.
  • the fan blades protrude with their front as well as with their trailing edge beyond the end faces of the hub ring. In this respect, the trailing edge running straight into the innermost region forms an axial projection of the fan blade relative to the hub ring.
  • the axial fan has a hub ratio D i / D a of greater than 42%, wherein the hub ratio is the quotient of hub diameter and outer diameter of the fan blades.
  • the axial projection of the blade trailing edge in the inner region has a particularly advantageous effect on fans with a relatively large hub ratio, since this unfavorably affects the efficiency and the volume flow promoted by the fan - in this case results here a compensation.
  • the larger hub ratio may result due to a smaller outer diameter when the blades are cut due to power grading.
  • the axial fan is firmly connected via its hub ring with a fluid friction clutch, which in turn is driven by the internal combustion engine and drives the fan with a regulated output speed.
  • a fluid friction clutch which in turn is driven by the internal combustion engine and drives the fan with a regulated output speed.
  • the diameter of the fluid friction clutch and thus the hub diameter increases, which can lead to a larger hub ratio.
  • the blade supernatant according to the invention which leads to an increase in the efficiency and the volume flow, has a particularly positive effect.
  • the advantage here is a low accumulation of material in the region of the connection of the fan blade and hub ring and increased strength.
  • Fig. 1 shows an arrangement of fan blades 1, 2 of an axial fan according to the prior art.
  • the direction of rotation of the fan is indicated by an arrow D.
  • the fan blades 1, 2 each have on their pressure side Hub ramps 3, 4 and leaf trailing edges 1a, 2a on.
  • the trailing edges or trailing edges 1a, 2a called, in their radially inner region, ie within the hub ramp 3, 4 each have recesses or grooves 5, 6.
  • Such recesses and shortening of the fan blade width were made in the prior art, because on the one hand mean a weight savings and on the other hand was the view that the fan blade in the blade root area brings no more power gain.
  • arrows W Due to the flow around the blade trailing edge in the region of the groove 5, a wake shown by the arrows W results, which leads to a reduction of the fan efficiency, a reduction of the volume flow and to an increased noise.
  • Fig. 2 schematically shows an inventive design of fan blades 7, 8 and the blade trailing edges 7a, 8a.
  • the direction of rotation of the axial fan is again indicated by an arrow D.
  • On the printed pages of the fan blades 7, 8 hub ramps 9, 10 are arranged, which divide the blade trailing edges 7a, 8a in a radially outer and a radially inner region.
  • the radially inner region of the blade trailing edge 7a extends substantially straight, ie a substantially straight course takes place from the transition from the outer region to the inner region.
  • the blade width of the fan blade 7 is increased relative to the blade width of the fan blade 1 according to the prior art in the radially inner region, so that no groove takes place.
  • This enlarged area is highlighted by a bold contour 7b.
  • the effect of the increased blade width in region 7b is an inhibition of in Fig. 1 illustrated lossy cross and / or Backflow.
  • the flow shown by arrows S is largely undisturbed radially outside the hub ramp 10 on the fan blade 8.
  • a relatively stable and eddy-free flow indicated by arrows P, also forms below the hub ramp 10.
  • the extension of the blade trailing edge in the radially inner region 7b, ie the enlargement of the blade width brings a significant increase in the volume flow and the efficiency and a noise reduction.
  • bucket width or blade width mean the distance between the leading edge and the trailing edge or the length of the tendon of the bucket or the blade.
  • the depth of the blade is understood to mean the projection of the blade width in the circumferential direction.
  • Fig. 3 shows a section of an axial fan 11 according to the invention in a 3D representation.
  • the illustration shows a hub ring 12, to which fan blades 13, 14, 15 attached, that are integrally molded.
  • the fan blades 13, 14, 15 each have on their print pages hub ramps 13a, 14a, 15a, which rise against the direction indicated by an arrow D direction of rotation.
  • the hub ramps 13a, 14a, 15a are ribbed for reasons of strength with the hub ring on its underside.
  • the fan blades 13, 14, 15 each have trailing edges 16, 17, 18, also called trailing edges 16, 17, 18, which extend essentially in a straight line from radially outside to radially inside.
  • the trailing edges 16, 17, 18 are divided into two sections, namely radially outer sections or regions 16a, 17a, 18a and radially inner sections or regions 16b, 17b, 18b.
  • the inner portions 16b, 17b, 18b of the blade trailing edges 16, 17, 18 merge into the free edges of the hub ramps 13a, 14a, 15a via a radius or fillet R, the reference lines of the reference numerals 13a, 14a, 15a from the free edges out.
  • This creates a strength optimized fan structure that is capable of is to absorb the forces occurring during operation of the fan, in particular centrifugal forces.
  • the suction sides of the fan blades have fin-like stabilizers 19.
  • Fig. 4 shows a radial section (section in a radial plane) through the hub ring 12 of the axial fan 11, wherein the same reference numerals as in FIG Fig. 3 be used.
  • the air flow direction is shown by an arrow L.
  • the hub ring 12 has an axial extent a and the fan blade 14 has a depth t, which - as mentioned above - is defined as a projection of the blade width in the circumferential direction. From the graphic representation it is clear that the blade depth t is considerably greater than the axial extent a of the hub ring 12.
  • the blade depth t is in a preferred embodiment about twice as large as the axial extent a of the hub ring 12.
  • the trailing edge 17 of the fan blade 14 extends substantially straight in the radial direction, wherein the innermost portion of the trailing edge 17 is rounded.
  • the hub ramp appears as a cut surface designated 14a.
  • Fig. 5 shows a view of an incomplete axial fan 20 with a view towards the front or the suction sides of the fan blades 21, on which air guide elements 22 are arranged.
  • the axial fan 20 comprises a metallic carrier ring 23, which is on the one hand connected to the plastic hub of the axial fan 20 and on the other hand can be attached to a coupling, not shown, preferably a liquid friction clutch.
  • the fan blades denoted by the reference numerals 21a, 21b, 21c are cut off in the sectional plane VI-VI.
  • Fig. 6 shows a sectional view of the axial fan 20 according to sectional plane VI-VI.
  • the illustration shows different sectional areas of the fan blades 21a, 21b, 21c.
  • the section plane VI-VI in Fig. 5 shows the fan blades 21a, 21b, 21c, with respect to their radial center line in different Plane cut, wherein the cutting plane for the central blade 21b can be considered as a tangential section and lies radially within the hub ramp.
  • the sectional area of the sheet 21c in Fig. 6 is above the hub ramp, here denoted by the reference numeral 24 and in Fig. 5 is not recognizable, since it is arranged on the back of the fan blades 21.
  • the sectional area of the middle fan blade 21b, the blade width b, ie the distance between the front and rear edge, are removed.
  • the projection of the blade width b in the circumferential direction gives the (not shown) blade depth t, which is approximately constant over the entire radial region, namely at approximately rectilinear blade trailing edge.
