Definitions

  • the invention relates to a radial fan housing, which has at least one receiving recess for receiving a radial fan wheel, at least one air outlet and at least one air guide for guiding the air flow from the receiving recess toward the air outlet.
  • the invention further relates to a radial fan, a vehicle air conditioning system and a vehicle.
  • blowers or ventilation are known, which are also used in practice.
  • Typical designs are, for example, axial fans or radial fans.
  • blowers or fans are used in the ventilation or air conditioning of substantially enclosed spaces, such as, for example, of building interiors or vehicle interiors.
  • substantially enclosed spaces such as, for example, of building interiors or vehicle interiors.
  • a particularly frequent field of use are interior spaces of motor vehicles, such as passenger cars, commercial vehicles or buses and coaches.
  • radial fans have been successively improved over the years, they still produce a noticeably audible operating noise, especially with a higher airflow through the radial fan.
  • Particularly problematic are low-frequency noise components. Such low-frequency noise components are usually perceived by persons as particularly unpleasant. The resulting operating noise can be problematic especially in a recirculation mode of motor vehicle air conditioning systems, since then the operating noise of the radial fan can easily get into the passenger compartment via the suction port of the blower.
  • the object of the invention is thus to propose a low-noise radial fan.
  • a radial fan housing in particular a radial fan housing for the air conditioning system of a motor vehicle, which has at least one receiving recess for receiving a Radialgebläserads, at least one air outlet and at least one air guide for guiding the air flow from the receiving recess toward the air outlet, to the effect that the air guide at least on its the receiving recess facing inside the contour of the receiving recess substantially continues.
  • the air outlet may in particular be designed like a nozzle or tube-like and in particular lead away at least approximately tangentially from the receiving recess for the Radialgebläserad.
  • the cross section of the air outlet may, for example, be round, D-shaped (semicircular) or rectangular.
  • the air intake for the radial fan housing for example, in the axial direction (corresponds to the direction of the axis of rotation of the Radialzuffterrads).
  • a type of air intake hood in which a perpendicular to the axial direction (or tangentially and / or radially) arranged (seen relative to the radial fan) air intake opening is provided. This makes it possible, at least partially to suck air in the tangential and / or radial direction.
  • At least one air guiding device on its side facing the air outlet extends at least substantially tangentially to the receiving recess and / or at least substantially continues the contour of the air outlet.
  • the air outlet facing the side of the louver corresponds to the side facing away from the receiving recess side of the louver as a rule.
  • air turbulence may result in undesirable additional air resistance and / or additional operating noise.
  • the air guiding device typically has a wedge-like, a tongue-like and / or a V-shaped structure in the proposed embodiment.
  • the resulting wedge or the resulting tongue can be massively performed in any way or can also be provided to save material with a cavity.
  • the corresponding structure can also be "rounded” or “bent” or curved on its side facing the receiving recess, for example, so that it can follow, for example, the corresponding section of a circular receiving recess.
  • At least one receiving recess is formed spirally. This makes it possible to take into account the increase in the air volume flow along the outside of the radial fan by providing an increasing air passage cross-section. With such a training manner, it is usually possible to operate the radial fan with a particularly low power and / or to reduce the operating noise again.
  • At least one air guiding device is arranged asymmetrically, in particular laterally, in at least one receiving recess and / or with respect to at least one air outlet.
  • Experiments have shown that such an arrangement is surprisingly particularly noise-sensitive, in particular with regard to the low-frequency noise component.
  • Particularly good results have usually then set when the louver is arranged on the air intake opening facing side of the fan housing. In some experiments, however, better results were achieved, conversely, when the air guiding device is arranged on the side of the fan housing facing away from the air intake opening.
  • the at least one air guiding device in such a way that it has, at least in sections, an oblique front edge, which in particular at least in places has an angle of attack of 45 ° to 85 °, preferably 55 ° to 75 °, particularly preferably 60 ° to 70 °, in particular 63 ° to 67 °.
  • the angle of attack is defined as the angle between the leading edge of the air device and the axial direction of the radial fan.
  • the axial direction of the radial fan is usually parallel to the axis of rotation of the radial fan and perpendicular to the air outlet in the air outlet.
  • the leading edge of at least one air guiding device extends substantially rectilinearly at a substantially constant angle of attack.
  • erratic (random) surface structures and / or surface patterns having particular patterns lead to a particularly effective noise reduction
  • an at least substantially rectilinear shape and / or a substantially smooth surface structure are particularly noise-negative effect.
  • the air guiding device is formed at least in regions with a wave-shaped and / or with a stepped front edge.
  • a further preferred embodiment results if the height of at least one air guiding device is less than the height of at least one receiving recess and / or at least one air outlet, and preferably between 20% and 80%, more preferably between 30% and 70%, particularly preferably between 40 % and 60%, in particular between 45% and 55%.
  • the values mentioned can typically lead to a particularly strong noise reduction, especially in the low-frequency spectrum.
  • At least one air guide at least partially has a rounded trained top.
  • the proposed shaping can generally lead to particularly low operating noise of the radial fan, in particular in the low-frequency noise region.
  • Such a rounded configuration can be realized in particular in the form of a semicircular segment.
  • rectilinear wall regions can adjoin the semicircular segment. This can result in an approximately "D" -like shape (which may in particular have relatively long straight legs).
  • the radius of the semicircular segment corresponds approximately to the wall height of the rectilinear wall areas.
  • the radius of the semicircular segment changes corresponding to the position of the respective semicircular segment in the longitudinal direction of the louver, corresponding to the height of the respective rectilinear wall region. It is also possible, however, that the radius remains largely constant, but that the angular range of the circle segment changes (that is, there is no longer a semicircle segment, in most cases the angular range will be ⁇ 180 °). It is also possible to work independently that along the entire air guide only circle segments are provided with an angular range of for example ⁇ 180 °. Of course, mixed forms can also be realized.
  • the transition into optionally adjacent rectilinear wall regions by means of a sharp edge and / or by means of a rounded transition region. It should be pointed out that in some cases it may also prove expedient if at least one air guiding device has an essentially flat upper side, at least in regions. Even with such a shape can result in part a particularly strong noise reduction.
  • a further preferred embodiment of the radial fan housing is obtained when the suction direction at an angle of 210 ° to 310 °, preferably 220 ° to 300 °, more preferably 230 ° to 290 °, particularly preferably 240 ° to 280 °, in particular 250 ° to 270 ° to the outlet direction.
  • a very low operating noise especially in the low-frequency noise spectrum, may result.
  • a radial fan is proposed with at least one housing device and at least one radial fan, which has at least one radial fan housing according to the structure described above.
  • the radial fan then has the advantages and properties already described in connection with the radial blower housing in an analogous manner.
  • a vehicle air conditioning system in particular an automotive air conditioning system which has at least one radial fan housing according to the structure described above and / or a radial fan with the structure described above.
  • the vehicle air conditioning system then has the advantages and properties already mentioned in connection with the radial fan housing and / or the radial fan in an analogous manner.
  • a vehicle in particular a motor vehicle is proposed, which has at least one radial blower housing with the structure described above and / or at least one radial blower with the structure described above and / or at least one vehicle air conditioning system with the structure described above.
  • the vehicle then has the properties and advantages already described in connection with the radial blower housing, the radial blower or the vehicle air conditioning system in an analogous manner.
  • the vehicle may be any aircraft, vessel, and / or land vehicle (railbound / non-railbound).
  • a part of a radial fan 1 is shown in perspective view. More specifically, a part of the upper half 7 of the radial fan casing 2 (corresponding to the suction side half of the radial fan casing 2 in the present case) is shown.
  • Fig. 1 shows the area in which the air flow is diverted from the inlet opening, from the receiving area 5 in the radial fan housing 2 of the radial fan 3, or from the pressure chamber 6 located around the radial fan 3 in the radial fan housing 2 to the air outlet opening 9.
  • the radial fan 3 which is around at the in Fig. 1 selected perspective above the air intake opening 8 in the receiving area 5 is not shown.
  • the branching or guiding of the air flow into the air outlet channel 9 takes place in a manner known per se with the aid of a separating bead 10.
  • a part of the spirally formed pressure chamber wall or housing wall 11 can be seen limits the pressure chamber 6 in a radial direction. In the other direction, the pressure chamber 6 is limited by the outside 17 of the radial fan.
  • the height of the Lucasleitzunge 4 is in the present embodiment shown 50% (half) of the total height of the pressure chamber 6.
  • the pressure chamber 6, the receiving area 5 for the radial fan 3 and the height of the air outlet 9 are selected to be substantially identical in the illustrated embodiment. It should be noted that in Fig. 1 only the upper (suction side) half 7 of the radial fan housing 2 can be seen.

  • this small unevenness influences the mode of operation of the air duct 4 only to a small extent.
  • a particular advantage of the separate design of the air duct 4 is that the air duct 4 can be installed, for example as a retrofit solution in existing air conditioning. This not only applies to a service solution of units already in operation, but also to the construction of new air conditioning systems, since existing molds can continue to be used.
  • the Luftleitzunge 4 is formed integrally with (parts) of the radial fan housing 2.
  • the air duct 4 at the same time in the course of the manufacturing process of the radial fan housing 2.
  • the upper half 7 of the radial fan housing 2 could be manufactured by an injection molding process, during which the Heilleitzunge 4 is simultaneously formed. This makes it possible in particular to form the transition between the pressure chamber wall 11 and the inner side 14 of the Heilleitzunge 4 or the corresponding boundary wall 18 of the air outlet channel 9 and the outer side 15 of the Heilleitzunge 4 largely flat.
  • the angle of attack ⁇ of the upper side 13 of the air duct 4 is, in particular Fig. 1 and Fig. 4 can be taken as an angle between the top 13 of the air duct 4 and the axial direction 16 of the radial fan housing 2 and the radial fan 1 defined.
