Definitions

  • the invention relates to a radial fan housing for ventilation devices, in particular for ventilation devices of motor vehicles, which have at least one bounded by at least one receiving space boundary wall radial fan receiving space and a limited at least one channel wall McDonaldabloomal.
  • the invention relates to a blower device, in particular a blower device for a motor vehicle.
  • the invention relates to an air conditioner, in particular an automotive air conditioning system.
  • the invention relates to a method for operating a radial fan assembly.
  • the fan or blower must have different characteristics. While, for example, in a first application (such as in a radiator of a motor vehicle) primarily depends on a high air flow rate (and thus on a high cooling capacity), in other applications, for example, a particularly low operating noise (for example in the ventilation of a motor vehicle interior) in the foreground ,
  • radial fans For ventilation of interiors, in particular motor vehicle interiors, in particular radial fans have proven themselves. Basically, such radial fans satisfy the tasks assigned to them satisfactorily.
  • centrifugal fans A problem with the currently known centrifugal fans, however, is when they are to be used in strongly changing operating conditions, which is the case for example in the automotive sector. Here, it generally proves necessary to optimize the blower to one (or more) selected typical operating point. In the other operating points, however, disadvantages (such as poor efficiency, unnecessary high noise and the like) must be consciously accepted. It is easy to see that this is undesirable.
  • the object of the invention is therefore to propose a radial fan housing device, which is particularly universally applicable.
  • the object of the invention is to propose a blower device and an air conditioner, which is particularly universally applicable
  • the object of the invention It is to propose a method for operating a radial fan assembly, which allows a particularly universal operation of a radial fan assembly.
  • a radial fan housing device for ventilation devices in particular for ventilation devices of motor vehicles, which has at least one limited by at least one receiving boundary wall radial fan and an at least channel wall Heilab technicallykanal further such that the transition between the at least one receiving space boundary wall and the at least one channel wall forming tongue device is at least partially adjustable and / or the frame device is at least partially adjustable.
  • the adjustability of the tongue device or the frame device refers to a reversible adjustability. That is, the adjustability does not necessarily relate to an initial adjustment of the tongue device at the time of mounting the radial fan housing device or the complete radial fan assembly, respectively. Rather, it is possible to make an adjustment of the tongue device / the frame device also at later times.
  • the adaptability of the tongue device / frame device can be carried out during operation of the radial fan arrangement itself.
  • the adaptability of the tongue device relates in particular to its length, the distance to the radial fan, its thickness, its shape (cross section, bevel on the leading edge and the like), etc ..
  • the adaptation in the frame device refers in particular to their Diameter, their shape, their air passage cross-section whose position with respect to the tongue nose leading edge, etc. .. Incidentally, it is also possible that with the lengthening of the tongue device, the air passage cross-section is reduced and vice versa.
  • the tongue device and / or at least parts of the frame device have at least one actuator device and / or have at least one connection device for connection to an actuator device.
  • an actuator device for example, electrical control elements (electric motors, stepper motors and the like), mechanically acting actuator devices (control knobs, control levers, air-flowed flaps and the like), pneumatic actuator devices or other actuator devices can be used.
  • the tongue device has at least one, preferably a plurality, in particular two, three, four or five tongue wall elements. With such a design, a particularly good compromise between particularly good adjustability and relatively simple mechanical construction can usually be found.
  • the tongue wall elements themselves are designed as essentially rigid elements. The adjustability of the tongue device can then result at least partially by a change in position of the tongue wall elements against each other.
  • a particularly advantageous embodiment is obtained if at least one of the tongue wall elements is designed to be movable, in particular displaceable.
  • this movable arrangement of at least one of the tongue wall elements a change in position of individual assemblies of the tongue device can be achieved against each other.
  • a particularly great adaptability of the tongue device naturally results if a plurality, in particular all of the tongue wall elements (possibly also other assemblies of the tongue device) are designed to be movable.
  • At least one of the tongue wall elements has at least one at least partially asymmetrical and / or at least one at least partially symmetrical end face.
  • asymmetrical design at low air flow rates of the radial fan assembly is advantageous, while a symmetrical design at higher or high air flow rates of the radial fan assembly is advantageous.
  • the symmetry relates in particular to an axis symmetry relative to a longitudinal axis of the respective tongue wall element (which may in particular be perpendicular to the axis of rotation of the radial fan).
  • At least one of the tongue wall elements has at least one at least partially oblique, V-shaped, double-V-shaped, triangular and / or curved shape.
  • Such forms have proved to be particularly advantageous, in particular as particularly effective and / or noise reducing.
  • the V-shaped, double-V-shaped, triangular and / or curved shape can be formed both above, as well as in the form of a recess.
  • At least parts of the tongue device in particular at least part of the tongue wall elements and / or at least parts of the frame device, are designed to be adjustable independently of one another. With such a design, a particularly good adaptability of the radial fan assembly to the respective operating conditions (operating points) can be ensured.
  • the frame device may prove to be particularly useful if at least parts of the frame device are designed at least partially adjustable in terms of their shape and / or in terms of their diameter.
  • the adjustability can be done, for example, by partially covering using movable wall elements (including elements of the frame device). It is also possible, the frame device using a plurality of mutually displaceable wall elements (which can cover at least partially) form.
  • the frame device can be formed "like a glare" (for example analogously to shutters in cameras).
  • blower device in particular a blower device for a motor vehicle is proposed, which has at least one Radiali equally spacergepatusevorraum device having the structure described above.
  • the blower device then has the advantage and properties already described in an analogous manner.
  • an air conditioning system in particular an automotive air conditioning system with at least one radial fan housing device and / or with at least one fan device with the structure described above.
  • the air conditioning system then has the advantages and properties already described in an analogous manner.
  • Fig. 1 is a schematic plan view from above of a first embodiment of a radial fan 1 with adjustable tongue portion 8 is shown.
  • the radial fan 1 essentially consists of a housing 2 which has a spiral-shaped radial fan-wheel receiving area 3.
  • a radial fan 4 is arranged with a plurality of fan blades 9.
  • the air intake for the radial fan 4 takes place in the usual way from a frame, which is arranged for example in front of or behind the plane of the drawing. When the radial fan 4 is rotated, air is conveyed radially outward.
  • the thus-conveyed air flows into the spiral-shaped channel 10, which is formed by the outside of the radial fan 4 and the spiral wall 6 delimiting the radial fan receiving area 3. From there, the conveyed air is supplied via an air duct 5 to other areas of the vehicle air conditioning system 11, which is shown here only schematically, where it is heated, cooled and / or filtered, for example.
  • This tongue area 8 is in Fig. 2 shown in an enlarged view.
  • the tongue-nose front edge 15 may, for example, have a straight tongue-nose leading edge 15 running parallel to the drive axis 14 of the radial fan 4 (see also FIG Fig. 3a ).
  • a straight tongue leading edge 15 may prove advantageous under certain operating conditions of the radial fan 1. In particular, it can be at particularly high air flow rates with only a very small back pressure advantage because it blocks very small areas of the outside of the radial fan 4. If only a particularly low back pressure in the air duct 5 prevails, also backflow in the area of the tongue nose leading edge 15 are largely negligible. Since the - described in more detail below - sliding tongue walls 16, 17 are in their retracted position, the resulting tongue area leading edge 13 is determined by the shape of the tongue nose leading edge 15.
  • asymmetrical, v-shaped tongue leading edge 18 is advantageous.
  • a relatively short length of the tongue is still required in order not to block the air mass flow promotion in the tongue-near area.
  • a first, displaceably arranged tongue wall 16 is extended a little way forward (in FIG Fig. 1 and 2 to the left). The displaceability of the first tongue wall 16 (analogously, the second tongue wall 17) is in Fig.
  • a relatively long, asymmetrically shaped tongue is more advantageous in order to reduce the backflow.
  • the asymmetrical shape can particularly effectively prevent a return flow (in particular also an asymmetrical return flow, which may be due, for example, to the single-sided air supply through the frame 23, 24).
  • the second tongue wall 17 is pushed forward sufficiently far (with the first tongue wall 16 being retracted).
  • the effective, resulting tongue portion leading edge 13 A possible shape of the leading edge 19 of the second tongue wall 17 is in Fig. 3c shown.
  • the (maximum) travel of the second tongue wall 17 is greater than the (maximum) travel of the first tongue wall 16 is selected.
  • the radial fan 1 can not only be operated with "end deflections" of the first tongue wall 16 and / or the second tongue wall 17. Rather, it may prove to be particularly advantageous if intermediate positions are used to special To realize advantageous tongue configurations for certain operating points.
  • the radial fan housing device 1 in particular its first tongue wall 16 and / or its second tongue wall 17 are designed such that a constant (minimum) distance of the corresponding wall surface is maintained to the radial fan 4.
  • the respective relative angles of incidence between the leading edges 15, 18, 19, 20, 21, 22 of the corresponding tongue walls and the airflow passing them may be determined for various operating points using CFD calculations.
  • radial fan 1 with adjustable frame 23 24 are shown.
  • the adjustable frame 23 is formed such that its diameter between a maximum diameter 25a and a minimum diameter 25b can be adjusted.
  • the adjustable frame 24b is formed variable in terms of their shape using a sliding cover plate 26.
