Definitions

the invention relates to an air guide arrangement for a centrifugal fan in a ventilation and air conditioning system, preferably for a channel-shaped housing having a rectangular, round or square cross-section.
Air guide assemblies and air deflection devices are known in the prior art in different designs.
the simplest embodiments are sheets, with which the flow direction is deflected in an air flow.
An air deflecting device is, for example, from DE 89 08 987 U known.
the deflection of the air takes place from the radial to the axial direction exclusively on the housing wall of the conveying channel.
the air conveyed outwards by the blades occurs in the radial direction on the walls of the delivery channel housing.
This leads to strong flow losses and to a strong noise.
it can in this case in the outflow gap between the Abströmblech and the housing wall opposite, close to the dividing area lead to strong turbulence, which not only reinforce the mentioned disadvantages, but above all unfavorable to a flow control by changing the gap between the inlet and inlet of the fan wheel.
the DE 4129211 A1 is concerned with achieving a gentle deflection of the pumped medium and avoiding turbulence in the region opposite the outflow gap. This is achieved in that the conveying channel is provided with a deflecting funnel which comprises at least the suction-side edge region of the centrifugal fan impeller and has a spacing which extends in the transport direction of the gas as far as the conveying channel cross-section.
Radial fans are well known and include an impeller driven by a drive motor.
the impeller generally has on its downstream side a cover plate, to which the impeller blades adjoin.
the air is usually sucked parallel to the drive axis of the centrifugal fan in a radial fan, thus axially and deflected by the rotation of the impeller by 90 ° and blown out radially.
the sucked air is thus radially outward, d. H. blown in the direction of the wall of a channel-shaped housing. So that the air on the pressure side of the centrifugal fan, d. H. on the downstream side, flowing again in the main flow direction, the air flow must be redirected again at the wall by 90 °. This creates eddy and an undesirable pressure loss, which reduces the overall efficiency of a centrifugal fan in such an application.
the invention is therefore based on the object to avoid the aforementioned disadvantages and to provide an arrangement in which the outflow of the transported air or gas quantity of the centrifugal fan is improved, so that as a result the efficiency is increased due to a lower pressure drop.
the aim is to allow the air flow taken in by a centrifugal fan to flow out into a channel-shaped housing as loss-free as possible.
a basic idea of the invention is to arrange the radial air flow of the radial fan via one or more baffle formations of specifically arranged and shaped baffles downstream of a radial fan so that the existing twist is reduced by the baffles are used against the spin direction.
the flow cross-section is widened along the baffle formation, thereby achieving a diffuser effect.
an air guiding arrangement which is designed for a ventilation system with a channel-shaped housing and a radial fan arranged in a cross-sectional plane in the housing, wherein the air guide arrangement comprises at least one baffle formation of a plurality of differently oriented air baffles, wherein an air passage between the baffles Leitblechformation (s) and the interior of the housing is formed so that the existing swirl is reduced by the baffles are oriented counter to the twisting direction.
further Leitblechformation is formed as a substantially pyramidal and / or funnel-shaped Leitblechformation with a square or rectangular cross section, which preferably corresponds to the cross section of the channel-shaped housing in which the air guide assembly is intended to be used ,
this suction-side guide plate formation is formed or formed from four substantially flat, trapezoidal air guide plates which are each connected at an angle ⁇ to a base plate arranged in the cross-sectional plane of the housing and acting as a nozzle with a central opening.
a pyramidal baffle formation is provided in which the side walls are preferably oriented at an angle ⁇ between 45 ° and 80 ° relative to the cross-sectional plane.
the guide plate formation arranged downstream, which is to be provided downstream of the radial fan, as a substantially pyramid-shaped or funnel-shaped Leitblechformation is formed with a running in the cross-sectional plane of the housing base with a substantially square or rectangular cross-section.
downstream baffle formation is formed of four pairs arranged in each case twice folded air baffles, which are folded and arranged to each other, that results in the aforementioned pyramidal or funnel-shaped baffle formation.
the individual baffles each form a triangular sheet metal section, which in each case forms a partial segment of the base of the downstream baffle formation.
this triangular plate section is followed by a substantially bent in the axial direction of the centrifugal fan or bevelled rectangular sheet metal section with two side edges, wherein the baffles are preferably arranged rotated by an angle of 0 ° to 20 ° with respect to the axial direction.
a further Belchabites is formed on the respective baffle as an angled fin and preferably at the triangular sheet metal section.
the bending angle of the two baffles of a baffle pair of the respective rectangular sheet metal sections with respect to the triangular sheet metal sections is different and with a difference angle ⁇ of about 3 ° to 10 °.
a difference angle ⁇ of about 3 ° to 10 °.
the same angle are conceivable.
downstream baffle formation is formed of four each along an edge angled air baffles, each with a first flat trapezoidal baffle section, which under a defined angle of attack on a formed in the cross-sectional plane arranged base plate are formed.
the angled air guide plates adjacent to the said edge each form a downstream flat preferably also trapezoidal Leitblechabêt which is oriented at a larger angle than the angle of attack of the aforementioned Porterblechabitess relative to the cross-sectional plane.
the first and / or second guide plate formation has at least one plurality of preferably rectangular and / or curved air guide vanes, which extend in the radial direction.
the plurality of air guide vanes can be connected or arranged on the outer surface of the air guide plates of the downstream guide plate formation or on the inner surface of the first guide plate formation.
the majority of the air guide vanes extends as far as possible to the outside so that they extend to the inner wall of the housing in the installed state of the air guide.
the majority of the air guide vanes extend as far as possible to the inside so that they extend in the installed state of the air guide arrangement to the outer contour of the radial fan (viewed in the axial direction).
Another aspect of the present invention relates to an air guide assembly as described above, which is at least partially disposed around a radial fan in a channel-shaped housing of a ventilation system, wherein a Leitblechformation as described above downstream of the centrifugal fan is arranged.
FIGS. 1 to 12 explained with reference to the description of the various embodiments, wherein like reference numerals indicate structurally and / or functionally identical components.
a sectional view through a channel-shaped housing 30 of a ventilation system ventilation system is shown in which a radial fan 40 is arranged with fan blades 41, which can be rotated by a motor 42 in rotation. Indicated is an air flow whose course is shown schematically with the aid of the illustrated arrows.
the radial fan sucks air axially via the intake opening A, which is then transferred in the area of the fan blades 41 first into a radial and then downstream again into an axial flow.
FIG. 6 is a perspective view of an embodiment of an air guide assembly 1 and next to it a sectional view of this air guide assembly 1 in a channel-shaped housing 30 with a centrifugal fan 40 is shown.
this exemplary embodiment will be described to explain the geometries of the air guide assembly 1 in particular with respect to the radial fan 40 and the housing 30 in more detail.
the air guide assembly 1 is arranged around the arranged on the cross-sectional plane E radial fan 40 around.
This air guide assembly 1 shows in addition a suction-side baffle 10 of four each oriented at 90 ° angle offset to each other air baffles 11. These can also from a single accordingly Between the air baffles 11, 21 of the baffle formations 10, 20 and the interior 31 of the housing 30, an air passage 2 is formed, due to the different angles of attack ß1, ß2 of the sections of the air baffles 21, the effective flow cross-section for the conveyed by the radial fan 40 air in the flow direction S increases in this area.
the baffle 10 represents a substantially funnel or pyramid-shaped baffle 10 with a square cross-section. This is formed of four flat, interconnected trapezoidal baffles 11, each arranged at a same angle ⁇ at one in the cross-sectional plane E, as a nozzle acting provided with a central opening base plate 12 are connected.
the angle of attack ⁇ of the air baffles 11 is preferably between 45 ° and 80 °.
the downstream baffle formation 20 is formed from a bent along an edge K (deflected) air baffle 21, which forms four sheet metal segments.
This guide plate formation 20 represents a substantially funnel-shaped baffle formation with a square cross section.
Each of the four segments of the baffle 21 has a first flat baffle section 21a, which is connected at an angle ⁇ 1 to the base plate 22 arranged in the cross-sectional plane E.
Each of the four segments of the Lucasleitbelchs 21 further comprises a downstream (adjacent to the first baffle portion 21a) flat baffle portion 21 b, which is oriented at an angle ⁇ 2 with respect to the cross-sectional plane E.
the angle of attack ⁇ 1 is preferably between 30 ° and 90 °, while the angle of attack ⁇ 2 is preferably between 90 ° and 100 °.
the ratio Xa / La of the distance Xa of the edge K of the Lucasleitbelchs 21 to the base 22 to the diameter La of the centrifugal fan is between 0.05 and 0.5. In this embodiment of the invention is due to the canted shape of the downstream Leitblechformation 20 an extension of the Flow cross section causes. This leads to a reduction of the flow velocity and thus to an increase of the static Pressure.
the axial length of the baffle portion 21 b measured from the edge K to the trailing edge is denoted by Xb.
a preferred choice for the ratio Xb / La is in the range of 0.15 to 0.8.
Preferred sizes for Yb / LA are between 1.1 and 2.0.

the second guide plate formation 20 is formed from four paired folded-edge air guide plates 21.
the shape of the individual air baffles 21 is in the FIG. 3 clearly visible.
the individual baffles 21 each form a triangular sheet-metal section 21d, which in each case forms a partial segment of the base 22 of the downstream baffle formation 20.
At this triangular sheet metal portion 21d is a substantially to the axial direction of the radial fan 40 bent or folded rectangular sheet metal section 21 e with in each case two side edges 21k, wherein the baffles preferably by an angle ⁇ of 0 ° to 20 ° with respect to the axial direction are arranged twisted (see Fig. 5 ).
a further Belchabites 21f is formed on the respective air guide plate 21 as an angled fin and preferably at the triangular sheet metal portion 21 d.
the bending angle ß1 of the two baffles of a baffle pair of the respective rectangular sheet metal sections 21e with respect to the triangular sheet metal portions 21d is different in such a way that this difference angle is about +/- 3 ° to +/- 10 °, which in the sectional view of Fig. 2 you can see.
This difference angle results from the fact that one sheet is rotated around the Ankathete and the other sheet around the Hypotenuse.
the ratio Yb / La of the outer edge dimension of the outer guide geometry Yb and the diameter La of the centrifugal fan typically corresponds to values between 1.5-2.0.
For the angle ß1 typically angles between 20 - 80 ° are used.

This embodiment has supplementary to the execution of the Fig. 6 at the air corpse 21 on a plurality of rectangular and curved shipsleiterieln 23 which extend in the radial direction to the inner side 31 of the housing 30.
the angle of attack ⁇ of the guide vanes 23 with respect to the axial direction is optionally carried out at an angle of 0 ° to 60 °, as well as in the embodiment of Fig. 8 is shown.
the guide vanes 23 cause the existing twist of the air as lossless redirect in the axial direction, which increases the efficiency of the fan.
profile shape typical profile shapes (for example NACA profiles) or even simple sheet metal geometries can be used.
the ratio SL / La between the chord length SL and the diameter La of the centrifugal fan is preferably between 0.05 and 0.4.
the ratio between the axial distance Xi of the guide vanes 23 and the diameter La of the centrifugal fan is preferably between 0 and 0.8.
FIG. 8 and 9 further embodiments of an air guide 1 are shown.
the air guide vanes 23 are similarly oriented, as in the embodiment of FIG. 7 , but attached to the housing 30.
the first and second guide plate formation 10, 20 connected to each other.
the dimensions are chosen as follows: the ratio Xd / La is between 0.3 and 0.7, the ratio Xe / La is between 0.1 and 1.0, the ratio of Ya / La is between 1.5 and 2,0 and the angle ⁇ is between 45 ° and 80 °, wherein the baffles 21 of the downstream Leitblechformation 20 extend approximately parallel to the wall of the housing 30.
FIGS. 10 and 11 show views of a further embodiment of an air guide assembly 1.
the guide plate formation 20 consists of a multi-folded sheet metal. This is folded in such a way that additional guide vanes 21s are formed which minimize the twist and deflect the flow of the air as loss-free as possible in the axial direction.
Fig. 12 is an execution similar to the FIG. 6 shown, however, the baffle formations 10, 20 of perforated plates with holes 14, 24 are formed.
the underlying cavity is lined with sound-absorbing material, which leads to an increased noise reduction. Such a sound-absorbing measure is also possible with the other versions.
