Definitions

  • the invention relates to a compact diagonal fan with a follow-up device.
  • Diagonal fans and their use are generally known from the prior art, for example from DE 10 2014 210 373 A1.
  • Diagonal fans are used in applications with high air performance requirements with higher back pressure and a small installation space, for example in cooling technology or extractor hoods. Due to the large motor diameter of diagonal fans in relation to the installation space Knife of the axially central motor, the blow-out area at the blow-out opening is relatively small, which leads to high outlet losses in the flow due to high dynamic pressure at the outlet of the diagonal fan.
  • Axial fans are usually used to achieve long throwing distances, but they require a not inconsiderable axial installation space. Diagonal fans are cheap for the compact design. They also have a larger area of application with higher back pressures with higher efficiency.
  • a disadvantage is the increased space requirement with axial outflow.
  • the invention solves the problem of providing a small axial length with good pressure increase for axially flowing diagonal fans.
  • a diagonal fan with an electric motor, a housing and a diagonal impeller which is accommodated within the housing and can be driven by the electric motor is proposed.
  • the diagonal flow generated by the diagonal impeller during operation is deflected by an inner wall of the housing in an axial flow direction.
  • the diagonal impeller is then seen in the axial flow direction
  • the diagonal fan also has an air outlet with a predetermined blow-out diameter B on the guide device.
  • the size of the blow-out diameter B is determined in relation to the total axial length E of the diagonal fan in such a way that 0.3 ⁇ E / B ⁇ 0.6 applies.
  • the combination of using the tracking device with pre- The correct blow-out diameter and the small overall axial length of the diagonal fan provide an increase in pressure increase and efficiency improvement in the case of axially outflowing diagonal fans.
  • the diagonal flow blown out by the diagonal impeller is deflected in the axial direction by the housing and is evened out by the after-guide device.
  • the special arrangement to each other also enables a long throw range with a compact axial design.
  • the diagonal fan has an air inlet with a predetermined intake diameter A, a ratio of intake diameter A to exhaust diameter B being fixed, that is 0.70 ⁇ A / B ⁇ 0.95. Due to a comparatively large suction diameter compared to the blow-out diameter, the radial deflection of the flow in the area of the inner wall of the housing, i.e. less in the radial outside area than in the radial inside area. This enables the use of an axially short guide device, since the radial component of the flow in the radial outer region must be reduced in particular for axial alignment or deflection.
  • the diagonal fan has an inlet nozzle which is arranged on the suction side of the housing.
  • the inlet nozzle then determines the intake diameter A.
  • the follow-up device has an axial extent C and the diagonal impeller has an axial impeller width D, the ratio of axial extent C to impeller width D being fixed, that is 0.30 ⁇ C / D ⁇ 0.75, in particular 0, 4 ⁇ C / D ⁇ 0.5.
  • an advantageous embodiment provides that the after-guiding device is formed in one piece with the housing.
  • the number of parts and assembly steps can be reduced.
  • a seal between the components can also be dispensed with.
  • the follow-up device has a protective grille that extends over a blow-out 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.
  • a variant of the diagonal fan is also favorable, in which the secondary guide, the housing and the protective grille are formed in one piece.
  • the protective grille also has a multiplicity of ring webs arranged coaxially to one another, each of which forms web surfaces that run parallel and opposite to the axial flow direction. The flow thus runs in parallel along the web surfaces over the entire axial length of the protective grille.
  • the annular webs in the area of the guide vanes are designed to protrude axially to a leading edge of the respective guide vanes.
  • the guide vanes can thus also be formed in part by the projecting section of the ring webs, so that the web surfaces formed by the ring webs in the region of the guide vanes are axially enlarged.
  • the axially projecting portions of the ring ridges can serve as stiffening of the guide vanes.
  • the guide vanes of the guide device can have different shapes and cross sections.
  • the guide vanes are curved in the shape of an arc as seen in the axial cross section and are additionally or alternatively profiled.
  • An aerofoil shape ie a convex arched shape, can be determined as the profiled shape. Therefore, the different flow angles of the respective used diagonal impeller are taken into account.
  • a straight radial extension of the guide vanes is also possible.
  • the guide vanes of the after-guide device can be designed to be three-dimensionally curved, i.e. the curvature is also axial.
  • the diagonal impeller also includes a hub with impeller blades attached or formed thereon.
  • the two hubs or hub areas are preferably dimensioned in such a way that a maximum diameter G of the hub area of the guide device is larger than a maximum diameter F of a hub of the diagonal impeller, so that the hub area of the guide device sees the hub of the diagonal wheel in axial projection covered.
  • the after-guide device has a motor mount for the electric motor in the hub area.
  • the hub area of the guiding device can also be designed to be axially retracted, so that motor components and guiding device overlap as seen in radial section.
  • an advantageous embodiment of the diagonal fan also provides that the diagonal impeller has a centrifugal ring which surrounds impeller blades distributed in the circumferential direction.
  • the centrifugal ring enables a precisely adjustable outflow angle and a flow line at a predetermined angle with respect to the axis of rotation of the diagonal impeller.
  • Another advantageous aspect is to design the electric motor as an external rotor motor in the case of the diagonal fan. 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 axially into the centrifuge ring, so that the inlet nozzle and the centrifugal ring overlap in sections as seen in the radial section.
  • FIG. 1 is an exploded perspective view of a Diagonalven tilators with a view of the inlet side
  • FIG. 2 shows an exploded perspective view of the diagonal fan from FIG. 1 with a view of the outlet side;
  • FIG. 3 shows a view in radial section of the diagonal fan from FIG
  • Fig. 4 is a perspective sectional view of the diagonal fan

  • the slinger 14 has a radially outward widening in the axial direction of flow, directed towards the inner wall of the housing 2 Strö flow cross-section.
  • 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, ie along the axis of rotation, the electric motor 5 extends into the central depression 11, so that it can be positioned closer to the diagonal impeller 4.
  • the diagonal impeller 4 driven via the electric motor 5 is arranged within the housing 2 forming 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 region of the diagonal impeller 4, so that the slinger 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 with respect to the axis of rotation at a predetermined outflow angle in the direction of the inner wall of the housing 2.
  • the outflow angle is followed by the centrifugal ring 14 determined obliquely radially outside.
  • the flow is then redirected again in an axial direction of flow and conveyed to the follow-up device 3.
  • the air outlet of the diagonal fan 1 has a predetermined blow-out diameter B, the ratio of total axial length E to blow-out diameter B being 0.38 in the exemplary 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 region of the smallest Flow cross section of the inlet nozzle), the diagonal fan 1 has an intake diameter A, which is a factor of 0.87 smaller than the blow-out diameter B.
  • the ratio can be adjusted in a range of 0.70-0.95. The required redirection of the flow in the radially outer area is thus small.
