Definitions

  • the invention relates to a diagonal fan in a compact axial design and with a simultaneously high throw distance.
  • Diagonal fans and their use are generally known from the prior art, for example from the DE 10 2014 210 373 A1 .
  • Diagonal fans are used in applications with high airflow requirements, higher back pressure, and limited installation space, for example in refrigeration technology or cooker hoods. This is due to the relatively large motor diameter of diagonal fans compared to their installation space. Due to the axially centrally arranged motor, the discharge area at the discharge opening is relatively small, resulting in high exit losses during flow due to high dynamic pressure at the outlet of the diagonal fan.
  • Axial fans are typically used to achieve long throw distances.
  • diagonal fans are advantageous for compact design.
  • the invention solves the problem of achieving both aspects of a compact design while simultaneously achieving a long throw distance and pressure increase.
  • a diagonal fan comprising an electric motor, a housing, and a diagonal impeller housed within the housing and driven by the electric motor.
  • the diagonal flow generated by the diagonal impeller during operation is deflected into an axial flow direction by an inner wall of the housing.
  • a guide vane assembly with a plurality of circumferentially distributed guide blades is arranged downstream of the diagonal impeller. This guide vane assembly homogenizes the airflow generated by the diagonal impeller, with the guide blades having a radial extension from a hub region of the guide vane assembly to the housing.
  • the guide vane assembly is arranged at a specific axial distance from the diagonal impeller.
  • a point is defined at which an imaginary extension in the downstream angle of the diagonal impeller intersects the inner wall of the housing at an axial distance K from the diagonal impeller.
  • the guide vane assembly is axially extended in a region around the The intersection of the outflow angle and the inner wall of the housing is located at an axial distance H from the diagonal impeller, where 0.75 ⁇ K/H ⁇ 1.25 applies.
  • the outflow angle of the diagonal impeller is determined via the impeller blades or an optional additional centrifugal ring.
  • the measuring point on the guide vane is the foremost axial plane pointing towards the diagonal impeller, while on the diagonal impeller, the axial plane is defined by the radial outer edge of the impeller blades or, if a centrifugal ring is used, by its axial end pointing towards the guide vane.
  • the diagonal airflow expelled by the diagonal impeller is deflected axially by the housing and homogenized by the guide vane. This special arrangement enables a long throw range while maintaining a compact axial design.
  • the guide vane has a protective grille extending over the discharge section of the diagonal fan.
  • the axial length L of the protective grille is less than 50% of the maximum axial length C of the guide vane.
  • Another advantageous design variant of the diagonal fan is one in which the guide vane, the housing and the protective grille are formed in one piece.
  • the protective grid further comprises a plurality of coaxially arranged ring struts, each forming strut surfaces that run parallel to the axial flow direction and are opposite each other. The flow is thus guided parallel to the strut surfaces. over the entire axial length L of the protective grille.
  • the annular webs project axially towards the leading edge of the respective guide vanes.
  • the guide vanes can thus be partially formed by the projecting section of the annular webs, resulting in an axially increased web area formed by the annular webs in the guide vane region.
  • the axially projecting sections of the annular webs can serve to stiffen the guide vanes.
  • the guide vanes of the guide system can have different shapes and cross-sections.
  • the guide vanes are curved in an arc-like shape in axial cross-section and are additionally or alternatively profiled.
  • the profiled shape can, for example, be an airfoil shape, i.e., a convexly curved shape. This allows for the different angles of attack of the respective diagonal impeller to be accommodated. A straight radial extension of the guide vanes is also possible.
  • the guide vanes of the guidance device can also be designed in a further alternative three-dimensionally curved design, i.e. the curvature also takes place in the axial extent.
  • a favorable design of the diagonal fan also provides that the guide vanes of the guide device transition directly into the protective grille and thus interact directly in terms of fluid dynamics.
  • the diagonal impeller also includes a hub with impeller blades attached to or formed from it.
  • the two hubs or hub sections are preferably dimensioned such that the maximum diameter G of the hub section of the guide vane is not exceeded. is larger than a maximum diameter F of a hub of the diagonal impeller, so that the hub area of the guide device covers the hub of the diagonal impeller in axial projection.
  • a further advantageous solution for the axially compact design of the diagonal fan is characterized by the fact that the guide vane has a motor mount for the electric motor in the hub area.
  • the hub area of the guide vane can also be axially recessed for this purpose, so that the motor components and the guide vane overlap in radial section.
  • an advantageous embodiment of the diagonal fan features a diagonal impeller with a centrifugal ring that surrounds impeller blades distributed circumferentially.
  • the centrifugal ring allows for a precisely adjustable discharge angle and a flow path at a predetermined angle to the axis of rotation of the diagonal impeller.
  • Another advantageous aspect is the use of an external rotor motor for the diagonal fan. This allows the diagonal impeller to completely enclose the motor, minimizing the axial space requirement.
  • a further development of the diagonal fan provides that it includes an inlet nozzle which is arranged on the intake side of the housing.
  • the inlet nozzle preferably extends axially into the centrifugal ring, so that the inlet nozzle and the centrifugal ring overlap section by section when viewed radially.
  • Figure 1 shows an embodiment of a diagonal fan 1 according to the invention.
  • the diagonal fan 1 is shown in its assembled state and has a total axial length E.
  • the diagonal impeller 4 comprises several impeller blades 9 extending radially outward from the axially open hub 8, which are surrounded by the centrifugal ring 14.
  • the centrifugal ring 14 has a flow cross-section that widens radially outward in the axial flow direction and is directed toward 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 axially central recess 11, so that this is closer to the The diagonal impeller 4 can be positioned.
  • 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 draws in air axially via the diagonal impeller 4 and conveys it diagonally, i.e., relative to the axis of rotation, at a predetermined discharge angle towards the inner wall of the housing 2.
  • the discharge angle is primarily determined by the centrifugal ring 14.
  • the imaginary extension V in the discharge angle of the diagonal impeller 4, determined by the centrifugal ring 14, strikes the inner wall of the housing 2 at point P at an axial distance K from the diagonal impeller 4.
  • the axial plane at which the centrifugal ring 14 terminates serves as the measuring point for the distance K.
  • the measurement is taken at the axial plane defined by the radial outer edge of the fan blades 9, designated by the letter H'.
  • the flow is then deflected back into an axial flow direction and conveyed to the guide vane 3.
  • the diagonal impeller 4 is followed at a distance H by the guide vane assembly 3 with a plurality of circumferentially distributed guide vanes 7.
  • the ratio between the distances K/H is set to 0.8 in the illustrated embodiment.
  • the guidance device 3 further comprises an integral protective grid 17 with a plurality of coaxially arranged ring struts 13, each of which Parallel to the axial flow direction, opposing web surfaces 19 are formed.
  • the axial length L of the protective grid 17 corresponds to half the axial length C of the guide vane 3.
  • the maximum flow cross-section of the guide vane 3 (diameter B) is located on the discharge side in the region of the annular webs 13.
  • the guide vane 3 homogenizes the flow by means of the guide vanes 7 and the protective grid 17.
  • the guide vanes 7 extend axially through the protective grid 13 and thus penetrate the annular webs 13 as a kind of arc-shaped radial web, as is well known in Figure 2 can be seen.
