Abstract

Disclosed embodiments relate to a housing for a fan that is constructed by cutting, bending, and/or folding a single sheet of metal. A disclosed housing is configured to house a fan having a motor that is configured to rotate around an axial direction. The housing includes a first plate that is oriented in a plane that is perpendicular to the axial direction and substantially flat wall regions extending away from the first plate so as to be non-coplanar with the first plate. The housing further includes a second plate having an air intake nozzle, the second plate oriented perpendicularly to the axial direction and thereby oriented parallel to the first plate and located a first distance along the axial direction from the first plate, with the first distance being determined by a length of the wall regions. The wall regions are configured to include air flow openings.

First claim

The invention claimed is:

1. A housing for a fan, comprising:
wall regions forming the housing,
wherein the wall regions are substantially planar or flat,
wherein the wall regions are manufactured from substantially regionally planer shaped parts,
wherein the wall regions intersect with each other in a straight line or to form an angle with respect to one another,
wherein a shaped part on a bottom disk side is arranged in parallel to and at a distance from a nozzle plate of the fan to which the housing is mounted or a shaped part on a nozzle plate side, wherein the distance is defined by planar shaped parts arranged to form side parts; and
wherein the planar shaped parts which form the side parts also form a stabilization region which extends part of the way between a nozzle plate of a fan to which the housing is mounted and the bottom disk side, and wherein the planar shaped parts along the stabilization region extend substantially around the entire circumference in a substantially closed manner.

2. The housing according to claim 1 , wherein the wall regions form an approximately 90° rotational symmetry.

3. The housing according to claim 1 , wherein the shaped part on the bottom disk side is angular or square or has chamfers or radii, the chamfers or radii having a convexly curved outer contour, the shaped parts-part not having corners.

4. The housing according to claim 1 , wherein the side parts are formed from 1, 2 or 3 planar subregions which intersect with each other in a straight line or at an angle to one another to form the respective side parts.

5. The housing according to claim 1 , wherein the side parts, viewed in an axial direction, extend over a through-flow region and, viewed in the circumferential direction, only partially extend over the respective side of the housing and, with their thus reduced area, block a part of the actual through-flow area and define air outlets with openings thus formed between adjacent side parts in the circumferential direction.

6. The housing according to claim 5 , wherein the side parts each have an inflow-side and an outflow-side edge, wherein the air outlets each extend between the outflow-side edge of one part of the side parts and the inflow-side edge of an adjacent one of the side parts in the rotational direction of an associated fan impeller of a fan to which the housing is mounted.

7. The housing according to claim 6 , wherein the inflow-side and/or outflow-side edges are configured to extend obliquely to an axis of the fan to which the housing is mounted, and have an angle of between 5° and 45° in relation thereto.

8. The housing according to claim 6 , wherein the inflow-side and/or outflow-side edges are provided with waves, serrations, or other flow-influencing measures in a sense of trimming the substantially planar wall regions.

9. The housing according to claim 1 , wherein the planar or flat wall regions are at least largely integrally manufactured by trimming and folding or bending a sheet metal plate.

10. The housing according to claim 1 , wherein a side length of a substantially square footprint of an enveloping cuboid of the housing is approximately 1.4 to 1.8 times a mean diameter of a blade trailing edge of an impeller of a fan to which the housing is mounted.

11. The housing according to claim 1 , wherein the housing is configured to be installed within an air duct having multiple air outlets.

12. The housing according to claim 11 , wherein the housing is configured to be installed at a bottom of the air duct.

13. The housing according to claim 12 , wherein the housing is configured to be installed via damper elements.

14. The housing according to claim 1 , further comprising a fan installed in the housing.

15. The housing according to claim 1 , wherein the housing is configured for use with a radial or diagonal fan.

16. A housing for a fan, comprising:
wall regions forming the housing,
wherein the wall regions are substantially planar or flat,
wherein the wall regions are manufactured from substantially regionally planer shaped parts,
wherein the wall regions intersect with each other in a straight line or to form an angle with respect to one another,
wherein a shaped part on a bottom disk side is arranged in parallel to and at a distance from a nozzle plate of the fan to which the housing is mounted or a shaped part on a nozzle plate side, wherein the distance is defined by planar shaped parts arranged to form side parts; and
wherein the side parts, viewed in an axial direction, extend over a through-flow region and, viewed in the circumferential direction, only partially extend over the respective side of the housing and, with their thus reduced area, block a part of the actual through-flow area and define air outlets with openings thus formed between adjacent side parts in the circumferential direction; and
wherein the side parts each have an inflow-side and an outflow-side edge, wherein the air outlets each extend between the outflow-side edge of one part of the side parts and the inflow-side edge of an adjacent one of the side parts in the rotational direction of an associated fan impeller of a fan to which the housing is mounted; and
wherein the inflow-side and/or outflow-side edges are configured to extend obliquely to an axis of the fan to which the housing is mounted, and have an angle of between 5° and 45° in relation thereto.

17. A housing for a fan, comprising:
wall regions forming the housing,
wherein the wall regions are substantially planar or flat,
wherein the wall regions are manufactured from substantially regionally planer shaped parts,
wherein the wall regions intersect with each other in a straight line or to form an angle with respect to one another,
wherein a shaped part on a bottom disk side is arranged in parallel to and at a distance from a nozzle plate of the fan to which the housing is mounted or a shaped part on a nozzle plate side, wherein the distance is defined by planar shaped parts arranged to form side parts; and
wherein the side parts, viewed in an axial direction, extend over a through-flow region and, viewed in the circumferential direction, only partially extend over the respective side of the housing and, with their thus reduced area, block a part of the actual through-flow area and define air outlets with openings thus formed between adjacent side parts in the circumferential direction; and
wherein the side parts each have an inflow-side and an outflow-side edge, wherein the air outlets each extend between the outflow-side edge of one part of the side parts and the inflow-side edge of an adjacent one of the side parts in the rotational direction of an associated fan impeller of a fan to which the housing is mounted; and
wherein the inflow-side and/or outflow-side edges are provided with waves, serrations, or other flow-influencing measures in a sense of trimming the substantially planar wall regions.
