Definitions

  • the invention relates to a fan according to the preamble of claim 1.
  • fans are known, with identical fan blades and identical fan blade connection geometries for all fan blades, ie a regularly repeated over the circumference of a fan housing geometry are configured.
  • a fan for an internal combustion engine which is drivable by means of a fluid friction clutch of an internal combustion engine via a drive shaft or a belt drive, wherein the fan has a fan housing with a plurality of fan blades formed thereon, and wherein the fan is designed such that it has different natural frequencies at least over a partial area.
  • the detuning of at least areas of the fan or the distribution of the natural frequencies caused by a corresponding design of the fan causes the reaction forces to be distributed over a broad frequency spectrum. This in turn causes the maximum component loads are reduced, so that the component costs can be reduced. Particularly distributive here is that cheaper bearings can be used.
  • At least two of the plurality of fan blades are designed such that they have different natural frequencies.
  • the reaction forces are advantageously minimized, so that in a structurally simple way, the cost, in particular the cost of the bearings can be reduced.
  • each of the plurality of fan blades is formed to have a natural frequency different from the other fan blades.
  • ribs are provided on each of the plurality of fan blades, the ribs being formed differently on at least two of the plurality of fan blades, particularly each of the plurality of fan blades.
  • a different number of ribs may be provided underneath each fan blade.
  • the ribs may be arranged differently with respect to their position and orientation.
  • the ribs are cooling fins.
  • the ribs are preferably arranged in the region of a hub of the fan.
  • At least two of the plurality of fan blades, in particular each of the plurality of fan blades, are formed with a different profile.
  • At least two of the plurality of fan blades, in particular each of the plurality of fan blades, have a different profile thickness distribution.
  • At least one of the plurality of fan blades is designed as a circular arc profile.
  • the maximum sheet thickness of at least one of the plurality of fan blades is shifted with respect to the center of the profile.
  • At least one of the plurality of fan blades has a local mass accumulation.
  • the local mass accumulation is provided in a blade tip region of the at least one of the plurality of fan blades. Also, a detuning of the fan blades can be achieved by material injections in a simple and thus cost-effective manner.
  • the fan has a flange, which is designed asymmetrically.
  • the flange ring is an insertion flange, which has a local weakening.
  • Fig. 1 shows a front view of a fan 1 in the air flow direction seen in the prior art, which is the promotion of cooling air through the radiator of a motor vehicle.
  • the fan 1 is designed as an axial fan and has eight axial blades or fan blades 2, which are arranged on a hub 4.
  • a fluid coupling 3 is provided, which has on its front side radially extending ribs 5, which serve as cooling ribs.
  • the fan 1 is connected in a manner not shown here with the output side of the fluid coupling.
  • the fluid coupling 3 is also driven via a central drive shaft 7.
  • the fluid coupling 3 ensures in a known manner that a fan blades 8 exhibiting fan blades 8 more or less fast depending on the cooling air temperature.
  • blade-shaped air guiding elements 6 are additionally arranged here, which serve to influence the air flow.
  • the direction of rotation of the fan is indicated by the arrow marked by A.
  • the fan blades 2 are arranged uniformly spaced around the circumference of the hub 4 and each have the same shape and size, d. H. All eight fan blades 2 are identical.
  • the cooling fins 5 are arranged uniformly or rotationally symmetrically about the axis of rotation of the drive shaft 7.
  • Fig. 2 is a sectional view of a profile of a single fan blade 2 according to the prior art.
  • This known profile of a Viscolmajers according to the prior art is designed as a circular arc profile, which has a thickness D 9 at a front edge 9 of the fan blade 2, which is identical to a thickness D 10 at a trailing edge 10 of the fan blade 2.
  • fan blade 2 is beyond the range of maximum thickness D max of the fan blade 2 in the middle M of the profile.
  • the natural frequency of the fan blade 2 can be easily changed. Also, a change in the natural frequency of the fan blade 2 can be caused by changing the thickness distribution of the profile. For example, it is possible to form the leading edge 9 with a different thickness D 9 than the thickness D 10 of the trailing edge 10 of the fan blade 2 to effect the change of the natural frequency of the fan blade 2.
  • Fig. 3 shows a front view of a portion in Lurtströmungsplatz a fan 1 according to an embodiment.
  • the fan 1 is provided with a plurality of fan blades 2, of which only a part is shown here, which on a hub 4 and a fan housing 12, in which also the fluid coupling 3 is received, are arranged.
  • the individual fan blades 2 differ in the embodiment in that they have different mass distributions from each other.
  • the fan blade 2 ' has a mass accumulation in a blade tip region 11.
  • the individual fan blades 2, 2 ' also have a different rigidity or material injections of different types.
  • Each of the already enumerated changes of the fan blades 2, 2 ' is suitable for causing a change in their natural frequency.
