Definitions

  • the invention relates to a centrifugal compressor with a diffuser which is used for example in an exhaust gas turbocharger for a motor vehicle.
  • Turbochargers generally consist of an exhaust gas turbine in an exhaust gas flow, which is connected via a turbo shaft with a compressor in the intake tract.
  • a turbine wheel and a compressor wheel are rotatably mounted on the turbo shaft, the turbine wheel being arranged in a turbine housing and the compressor wheel in a compressor housing having a diffuser.
  • the exhaust gas flow passing through the turbine housing drives the turbine wheel.
  • the turbine wheel in turn drives the compressor wheel, whereby the compressor increases the pressure in the intake manifold of the engine, so that during the intake stroke a larger amount of air in the
  • Cylinder passes. This means that more oxygen is available and a correspondingly larger amount of fuel can be burned. As a result, the power output of the engine can be increased.
  • the compressor Decisive for the noise emission of the turbocharger here is the compressor.
  • the compressor discharge radiates a lot of noise to the outside.
  • Radial compressors for turbochargers are known from the prior art, which have a diffuser, which converts the built-up speed in pressure. Such a diffuser ends in a so-called spiral which discharges the compressed air to the consumer.
  • the geometry of the transition of the spiral, ie the so-called tongue, is in this case a critical embodiment element, since pressure pulsations often arise at this point. According to the prior art, the problem of the formation of such pressure pulsations by a flow mentally favorable shaping of the tongue with a constant diffuser diameter or radius solved.
  • upstream silencers are frequently used. These silencers may have channel-like or backdrop-like elements, which in turn are lined, for example, with sound-absorbing material.
  • acoustic resonators and acoustical filters can also be used for sound damping.
  • the invention provides a radial compressor, in particular for a turbocharger, comprising: a volute and a diffuser, wherein the diffuser is designed such that a negative pressure area in the region of the transition of the volute casing or the tongue is at least reduced.
  • the radial compressor has the advantage that disturbing pressure pulsations can be prevented by reducing or suppressing a negative pressure area, which arises above all in the region of the transition of the spiral housing in the diffuser.
  • additional silencers are at least partially or completely dispensed with. This results in a significant saving in terms of manufacturing and assembly costs.
  • a more compact design can be achieved, for example, when used in a turbocharger.
  • the cross-section of the diffuser is varied such that the formation of a negative pressure area is at least reduced or substantially prevented altogether.
  • the cross section of the diffuser is varied by increasing the radius or the diameter of the diffuser in the region of the transition of the spiral housing or in the region of the tongue.
  • the cross section of the diffuser is varied by increasing the width of the diffuser.
  • the diffuser in the region of the transition of the spiral housing or in the region of the tongue has a larger or larger width.
  • Increasing the width of the diffuser leads to a equivalent effect, such as the enlargement of the radius of the diffuser. Again, the formation of a negative pressure area is prevented or at least reduced, so that disturbing pulsations can be contained and thus the occurrence of corresponding noise.
  • At least one wall or both opposing walls of the diffuser are inclined outwards and / or curved.
  • the respective wall can form a wedge shape, whereby the wedge shape increases towards the outside.
  • the walls can be identical or different in shape, inclination and / or curvature. This has the advantage that, depending on the function and intended use, the width of the diffuser can be easily achieved in at least one area by adapting both walls or even just one wall.
  • FIG. 1 shows a greatly simplified, schematic sectional view of a radial compressor and its diffuser according to the prior art
  • Fig. 2 is a greatly simplified sectional view through the compressor wheel and a diffuser according to
  • Fig. 3 is a highly simplified schematic sectional view of a radial compressor and its
  • Fig. 4 is a highly simplified sectional view through the compressor wheel and a diffuser according to
  • FIG. 3; 5 shows a greatly simplified, schematic sectional view of a radial compressor and its diffuser according to a second embodiment of the invention.
  • FIG. 6 shows a greatly simplified sectional view through the compressor wheel and a diffuser according to FIG. 5.
  • a radial compressor 10 is shown with a diffuser 12 according to the prior art, which is part of a turbocharger (not shown).
  • the radial compressor 10 is shown simplified from the front in a sectional view.
  • the radial compressor 10 in this case has a volute casing 14 and the diffuser 12.
  • the radius rl or the diameter of the diffuser 12 is constant.
  • the width bl of the diffuser 12 is constant as in the following
  • the diffuser 12 therefore has a substantially constant cross section.
  • a turbo shaft 16 is arranged, on which a compressor wheel 18 is provided.
  • the compressor wheel 18 is driven via a corresponding turbine wheel (not shown) on the turbo shaft 16.
  • air is sucked in axially by the speed of the compressor wheel 18 and accelerated to high speeds in the compressor wheel 18.
  • the air leaves the compressor wheel 18 while in the radial direction.
  • the diffuser 12 the velocity of the air is reduced. The consequence of this is that pressure and temperature increase.
  • the diffuser 12 is formed, for example, from a compressor rear wall and a part of the spiral housing 14.
  • the volute casing 14 the air is collected and the speed is further reduced until the compressor discharge.
  • Tongue 20 forms a critical execution element, since at this point often pressure pulsations arise because here can form a negative pressure area.
  • mufflers are provided to prevent or at least reduce disturbing noises as a result of such pressure pulsations.
  • FIG. 2 shows a sectional view through the diffuser 12 and through the compressor wheel 18 according to FIG. 1.
  • the width bl of the diffuser 12 is in this case kept substantially constant.
  • FIG. 3 shows a radial compressor 10 according to the invention, which is part of a turbocharger (not shown).
  • the radial compressor 10 also has a volute casing 14 and a diffuser 12.
  • a compressor wheel 18 and, for example, a turbine wheel (not shown) are arranged on a turboshaft 16, as previously described with reference to FIG. 1, a compressor wheel 18 and, for example, a turbine wheel (not shown) are arranged.
  • the diffuser 12 converts the built-up speed of the air sucked in via the compressor wheel 18 into pressure.
  • the diffuser 12 terminates in the spiral 13 of the spiral housing 14, which discharges the compressed air to the consumer.
  • the cross section of the diffuser 12 is changed according to the invention.
  • the cross section of the diffuser 12 is varied and is therefore not constant in contrast to the prior art.
  • This variation of the cross section can be realized in various ways, as will be explained in the following.
  • the radius r or the diameter of the diffuser 12 can be designed or changed as follows.
  • the radius r or the diameter of the diffuser 12 is embodied such that the formation of a negative pressure area is reduced or substantially no negative pressure area in the area of the tongue 20, i. in the area of the transition of the spiral, arises. This is achieved, for example, in that the radius r or the diameter of the diffuser 12 is increased in at least one predetermined area in order to reduce or substantially prevent the formation of a negative pressure area.
  • a radius r2 of the diffuser is therefore chosen to be larger in the region of the tongue 20 than a radius rl of the diffuser 12 outside this range.
  • the inventors have found that it is advantageous, for example, not to use a constant radius r or diameter in a diffuser 12 having a constant width, as has hitherto been the case in the prior art. Instead, it proves to be advantageous if the diffuser 12 is varied in its diameter or radius r. This means that the diffuser 12 has a slightly larger diameter or radius r 2 in at least one region, for example in a region of the transition of the spiral 13.
  • the diffuser 12 as shown in Fig. 3, for example, in the region of the tongue 20 and the transition of the spiral 13 with a larger radius r2 or larger diameter are performed.
  • the diffuser 12 is formed, for example, in the region of the tongue 20 with a curvature 30 to the outside or forms an oval in this area.
  • the illustration in Fig. 3 is greatly simplified and is only intended to explain the principle of the invention.
  • FIG. 4 further shows a sectional view through the compressor wheel 18 and the diffuser 12 according to FIG. 3.
  • the diffuser 12 has a substantially constant width bl.
  • FIG. 5 further shows a second embodiment of the radial compressor 10 according to the invention.
  • the radial compressor 10 has a constant diameter or radius rl. In order to vary the cross section of the diffuser 12 accordingly, the width b of the diffuser 12 is therefore changed in this case.
  • the width b of the diffuser 12 is varied in at least one region in order to counteract the previously described pressure pulsations, which arise, for example, in the region of the transition of the spiral 13.
  • the width b of the diffuser 12 is increased in this case, for example, as shown in Fig. 6.
  • the width bl is increased in the area shown to a width b2.
  • a first wall 22 of the diffuser 12 is formed in this area, for example, slightly inclined by an angle Y to the outside.
  • the first wall 22 can also be curved, for example.
  • an opposite second wall 24 of the diffuser 12 can also be adapted accordingly.
  • the width b of the diffuser 12, for example in the region of the transition of the spiral 13 or in the region of Tongue 20 varies or increased to a width b2, in order to counteract the formation of a negative pressure area in this area.
  • the diffuser 12 may in this case have a type of depression 26 in the form of a wedge 28, as shown in FIG. 5 in a front sectional view, and in FIG. 6 in a side sectional view.
  • the wedge 28 expands outward, for example, in the direction of the tongue 20.
  • At least one region or a plurality of regions of the diffuser 12 can be varied in their diameter or radius r. Furthermore, at least one area or several areas of the diffuser 12 can also be varied with respect to their width b. In this case, the regions are selected, for example, from the point of view where undesired pressure pulsations arise in order to adapt the selected regions in such a way that no or at most a small negative pressure region is created in order to counteract these pressure pulsations.
  • a diffuser 12 can also each have at least one region with a varied diameter or radius r, as has already been described in detail above with reference to FIGS. 3 and 4.
  • This diffuser 12 can optionally also be provided with at least one region whose width b is varied, as was explained in detail with reference to FIGS. 5 and 6.
  • the cross section of the diffuser 12 can be varied over the diameter or radius r and / or the width b.
  • first and / or second wall 22, 24 of the diffuser 12 can be inclined outwards and / or be formed curved to increase the width b of the diffuser 12.
  • the two walls 22, 24 may be formed identically or differently, ie, for example, with different inclinations or vaults.
  • the walls 22, 24 may also have different shapes in this area.
  • one wall 22, 24 inclined and the other wall 22, 24 may be curved, depending on the function and purpose.
