Definitions

  • the invention relates to a compact diagonal fan with a guide device.
  • Diagonal fans and their use are generally known from the state of the art, for example from EN 10 2014 210 373 A1 Further prior art in the present technical field is contained in the publications US 2012/039731 A1 , CN 101 265 923 A , US 2018/142704 A1 , DE 20 2009 017 511 U1 , US 2017/102007 A1 and "Operating Instructions" ( https://cdn.sos.sk/productdata/52/69/95e369fc/k2e200-ah20-05.pdf) disclosed.
  • Diagonal fans are used in applications with high air performance requirements with higher back pressure and limited installation space, for example in cooling technology or in extractor hoods. Due to the large diameter of the axially centrally arranged motor in diagonal fans in relation to the installation space, the exhaust area at the exhaust opening is relatively small, which leads to high exit losses in the flow due to high dynamic pressure at the outlet of the diagonal fan.
  • Axial fans are usually used to achieve high throw distances, but they require a considerable amount of axial space.
  • Diagonal fans are advantageous for compact construction. They also have a larger area of application with higher back pressures and at the same time are more efficient.
  • the disadvantage is the increased space required with axial outflow.
  • the invention solves the problem of providing a short axial length for axially flowing diagonal fans while at the same time providing a good pressure increase.
  • a diagonal fan is proposed with an electric motor, a housing and a diagonal impeller accommodated within the housing and driven by the electric motor.
  • the diagonal flow generated by the diagonal impeller during operation is diverted by an inner wall of the housing into an axial flow direction.
  • the diagonal impeller is followed by a guide device with a plurality of guide blades distributed in the circumferential direction, which evens out an air flow generated by the diagonal impeller.
  • the diagonal fan also has on the guide device an air outlet with a predetermined discharge diameter B.
  • the size of the discharge diameter B is determined in relation to the total axial length E of the diagonal fan such that 0.3 ⁇ E/B ⁇ 0.6.
  • the combination of the use of the guide vane with predetermined discharge diameter and small overall axial length of the diagonal fan provides an increase in pressure increase and efficiency improvement for axially flowing diagonal fans.
  • the diagonal flow blown out by the diagonal impeller is deflected in an axial direction by the housing and evened out by the guide vanes.
  • the special arrangement in relation to one another also enables a high throw distance while maintaining a compact axial design.
  • the diagonal fan has an air inlet with a predetermined intake diameter A, with a ratio of intake diameter A to discharge diameter B being specified, that is, 0.70 ⁇ A/B ⁇ 0.95. Due to a comparatively large intake diameter compared to the discharge diameter, the radial deflection of the flow in the area of the inner wall of the housing, i.e. in the radial outer area, is smaller than in the radial inner area. This enables the use of an axially short guide device, since for axial alignment or deflection, the radial component of the flow in the radial outer area in particular must be reduced.
  • the diagonal fan is provided with an inlet nozzle, which is arranged on the intake side of the housing.
  • the inlet nozzle then determines the intake diameter A.
  • the guide vane has an axial extension C and the diagonal impeller has an axial impeller width D, where the ratio of axial extension C to impeller width D is specified, that is, 0.30 ⁇ C/D ⁇ 0.75, in particular 0.4 ⁇ C/D ⁇ 0.5.
  • the diagonal fan provides that the guide device is formed as one piece with the housing. The number of parts and assembly steps can thus be reduced. Sealing between the components is also not necessary.
  • the guide device has a protective grille that extends over an exhaust section of the diagonal fan.
  • the axial length of the protective grille is less than 50% of the maximum axial length C of the guide device.
  • Another advantageous design variant of the diagonal fan is one in which the guide vane, the housing and the protective grille are formed as one piece.
  • the protective grille also has a plurality of ring webs arranged coaxially to one another, each of which forms opposite web surfaces running parallel to the axial flow direction. The flow is thus guided parallel along the web surfaces over the entire axial length of the protective grille.
  • the ring webs in the area of the guide vanes are designed to protrude axially towards a leading edge of the respective guide vanes.
  • the guide vanes can thus be partly formed by the protruding section of the ring webs, so that the web areas formed by the ring webs in the area of the guide vanes are axially enlarged.
  • the axially protruding sections of the ring webs can serve to stiffen the guide vanes.
  • the guide vanes of the guide device can have different shapes and cross-sections.
  • the guide vanes are are curved in an arc shape when viewed in axial cross-section and are additionally or alternatively profiled.
  • the profiled shape can be, for example, an airfoil shape, ie a convexly curved shape. This allows the different angles of attack of the diagonal impeller used to be taken into account. A straight radial extension of the guide vanes is also possible.
  • the guide vanes of the guide device can be designed to be three-dimensionally curved in a further alternative design, i.e. the curvature also occurs in the axial extension.
  • a favourable design of the diagonal fan also provides that the guide vanes of the guide device merge directly into the protective grille and thus interact directly in terms of flow.
  • the diagonal impeller also comprises a hub with impeller blades attached or formed thereon.
  • the two hubs or hub areas are preferably dimensioned such that a maximum diameter G of the hub area of the guide vane is larger than a maximum diameter F of a hub of the diagonal impeller, so that the hub area of the guide vane covers the hub of the diagonal impeller in axial projection.
  • the guide device has a motor mount for the electric motor in the hub area.
  • the hub area of the guide device can also be designed to be axially retracted so that the motor components and guide device overlap in radial section.
  • the diagonal fan is also designed such that the diagonal impeller has a centrifugal ring that encloses impeller blades distributed in the circumferential direction.
  • the centrifugal ring enables a precisely adjustable discharge angle and a flow line at a predetermined angle to the axis of rotation of the diagonal impeller.
  • Another advantageous aspect is to design the electric motor in the diagonal fan as an external rotor motor. This allows the diagonal impeller to enclose the motor and the axial space requirement is minimized.
  • a further development of the diagonal fan also provides that the inlet nozzle preferably extends in the axial direction into the centrifugal ring, so that the inlet nozzle and the centrifugal ring overlap in sections when viewed in radial section.
  • the diagonal fan 1 is shown in the assembled state and has a total axial length E.
  • the diagonal impeller 4 comprises a plurality of impeller blades 9 which extend radially outwards from the axially open hub 8 and are surrounded by the centrifugal ring 14.
  • the centrifugal ring 14 has a flow cross-section which widens radially outwards in the axial flow direction and is directed towards the inner wall of the housing 2.
  • the electric motor 5 is inserted into the axially open hub 8 of the diagonal impeller 4 and is completely enclosed by it. In the axial direction, i.e. along the axis of rotation, the electric motor 5 extends into the central axis depression 11 so that this can be positioned closer to the diagonal impeller 4.
  • the diagonal impeller 4 driven by the electric motor 5 is arranged within the housing 2 which forms a flow channel and has an axial length D.
  • the inlet nozzle 6 is arranged on the inlet side and extends with its end section of the smallest flow cross-section (diameter A) into the area of the diagonal impeller 4, so that the centrifugal ring 14 and the end section of the inlet nozzle 6 overlap.
  • the diagonal fan 1 sucks in air in the axial direction via the diagonal impeller 4 and conveys it diagonally, ie opposite the axis of rotation at a predetermined outflow angle in the direction of the inner wall of the housing 2.
  • the outflow angle is determined diagonally radially outwards via the centrifugal ring 14.
  • the flow is then diverted back into an axial flow direction and conveyed to the guide device 3.
  • the air outlet of the diagonal fan 1 has a predetermined blow-out diameter B, whereby the ratio of the total axial length E to the blow-out diameter B is 0.38 in the embodiment shown.
  • the ratio can be increased to 0.6 or reduced to 0.3.
  • the diagonal fan 1 In the air inlet 21 formed by the inlet nozzle 6 (in the area of the smallest flow cross-section of the inlet nozzle), the diagonal fan 1 has an intake diameter A that is smaller than the blow-out diameter B by a factor of 0.87.
  • the ratio can be adjusted in a range of 0.70-0.95. This means that the required deflection of the flow in the radially outer area is small.
  • the guide device 3 is arranged with a large number of guide vanes 7 distributed in the circumferential direction, as seen in the axial flow direction, following the diagonal impeller 4.
  • the guide device 3 also comprises an integral protective grid 17 with a large number of ring webs 13 arranged coaxially to one another, each of which forms opposite web surfaces 19 running parallel to the axial flow direction.
  • the axial length of the protective grid 17 corresponds to half the axial length C of the guide device 3.
  • the maximum flow cross-section of the guide device (diameter B) is in the area of the ring webs 13 on the outlet side.
  • the guide device 3 evens out the flow by means of the guide vanes 7 and the protective grid 17.
  • the guide vanes 7 extend in the axial direction through the protective grid 17 and thus break through the ring webs 13 as a type of curved radial webs, as can be seen well in Figure 2 can be recognized.
  • the diagonal impeller extends over an axial impeller width D.
  • the ratio of the axial extension C of the guide vane to the impeller width D has a value of 0.5 in the embodiment shown, but can be set in the range of 0.30-0.75, in particular between 0.4 - 0.5.
  • the ratio of the maximum diameter G the hub area of the guide vane 3 and the maximum diameter F of the hub 8 of the diagonal impeller 4 is also shown, where G>F.
  • the ring webs 13 in the area of the guide vanes 7 are designed to protrude axially to the leading edge of the respective guide vanes 7 in the section and thus ensure stiffening and support of the guide vanes 7.
  • the guide vanes 7 are curved in an arc shape both in the axial cross section and in the radial section according to Figure 3 curved radially outwards, resulting in a three-dimensional overall curvature.
  • the guide vanes 7 are curved in radial section according to Figure 3 profiled according to a support surface, whereby their respective thicknesses initially increase and then decrease again in the axial direction.
