1. A ventilator, in particular an axial, radial or diagonal ventilator, having a ventilator wheel and an outlet guiding device downstream of the wheel in a housing/flow channel, wherein the outlet guiding device comprises outlet guiding vanes extending only over a part of the housing/flow channel, as seen in a spanwise or radial direction.

2. A ventilator according to claim 1, wherein the outlet guide vanes extend over about half of the entire radial, spanwise housing/flow passage.

3. A ventilator according to claim 1 or 2, wherein the diameter of the outlet guide means is smaller than the diameter of the ventilator impeller.

4. A ventilator according to any one of claims 1-3, wherein the outlet guide vanes are connected, preferably at an outer end, to a preferably annular flow element/outer ring extending around a circumference.

5. A ventilator according to claim 4, wherein the annular flow element is substantially configured and arranged as a body of rotation or rotational symmetry relative to a ventilator axis.

6. A ventilator according to claim 4 or 5, characterized in that the annular flow element is implemented as an element conically tapering from the inlet side to the outlet side, so that the area near the outlet guide vane is adapted to be demolded from a casting mold without undercuts when seen from the axial direction.

7. A ventilator according to any one of claims 4-6, wherein the profile of the annular flow element is increasingly curved from its outflow-side end to its entry-side end, such that it has no or only a small angle of incidence with respect to a radial flow preferably flowing out from the impeller, and such that the flow is preferably deflected in an axial direction or parallel to the ventilator axis.

8. A ventilator according to any one of claims 1-7, wherein the outlet guide means has a structure that acts as a diffuser, having a gradually expanding flow cross-section when viewed in the flow direction.

9. A ventilator according to any one of claims 1-8, wherein the outlet guide vanes have a curved, preferably sickle-shaped, profile on their radial extension, in particular having a curve which is opposite to the direction of rotation of the associated impeller.

10. A ventilator according to claim 9, wherein the outlet guide vanes have an inclination angle of more than 30 °, preferably more than 45 °, with respect to the radial direction at least in a radially outer region.

11. A ventilator according to claim 9 or 10, wherein the outlet guide vane has a first inlet side region and a second outlet side region, wherein the inlet side region may have a profile cross-section of an airfoil having an inlet angle in the range of 20 ° to 50 ° relative to the ventilator axis at a leading edge of a profile midline, and/or wherein the outlet side region may extend parallel to the ventilator axis, and/or wherein transitions between regions may be configured to be tangentially constant or tangentially non-constant (e.g. curves).

12. A ventilator according to any one of claims 1 to 11, wherein the outlet guide means comprises or forms at least part of a suspension bracket.

13. A ventilator according to claim 12, wherein the outlet guiding device has means for its own suspension on its outer contour.

14. A ventilator according to claim 12 or 13, wherein a flange for attaching a motor is provided on an inlet side at the inner contour of the outlet guiding device, wherein the motor is preferably suspended with an associated ventilator wheel on the housing/flow channel by the outlet guiding device.

15. A ventilator according to any one of claims 12-14, characterised in that suspension struts, preferably made of flat material, extend between the annular flow element and the wall of the housing/flow passage and are arranged upright as seen in the axial direction and/or can be curved and/or inclined similar to the outlet guide vanes.

16. A ventilator according to any one of claims 12-14, characterised in that for attaching the outlet guide device one or more outlet guide vanes are extended towards the outside as far as the wall of the air guide channel or outer casing, thereby creating an integrated attachment means.

17. A ventilator according to any one of claims 1-16, wherein the guiding means is made of sheet metal and consists essentially of a planar area.

18. A ventilator with at least one impeller arranged inside a housing and a guiding device comprising a guiding element extending between a hub ring and an outer ring, which guiding element is also arranged inside the housing, wherein downstream of the impeller two flow areas are formed, an inner flow area closer to the axis when viewed in the spanwise direction being delimited by the hub ring of the guiding device and the outer ring of the guiding device, and an outer flow area further away from the axis when viewed in the spanwise direction being delimited by the outer ring of the guiding device and the wall of the housing, in particular with the additional features of any one of claims 1 to 17.

19. A ventilator according to claim 18, wherein an inlet side edge of the outer ring of the guiding device is arranged downstream of the impeller blades in the flow direction, wherein its position is located between the two ends of the impeller blades, preferably at about the center or in the range of 20-80% of the spanwise extension of the impeller blades, when seen in the spanwise direction.

20. An outlet guide apparatus for an axial, radial or diagonal ventilator with a ventilator wheel, having the features of the outlet guide apparatus of any one of claims 1 to 19.
