Definitions
- the present invention relates to a device for distributing air.
- An alternative designation is, for example, air distributor.
- Air distributor serve z. As in ventilation systems or in systems for controlling the temperature of rooms of the supply, discharge or generally the distribution of air.
- the air can be heated, for example, by a heater or air conditioning or z. B. have been adjusted with respect to the moisture content.
- Such air distributors are known, for example, from DE 10 2008 006 021 A1 or FR 2 965 334 A1.
- An air distributor can also be found in EP 0 639 744 A2. Here are located in a conically tapered chamber several Heilausströmö réelleen. Along a longitudinal axis of the chamber a plurality of plate-shaped elements are arranged, which have permeable storage surfaces and expand in the flow direction. The chamber tapers conically, wherein the plate-shaped elements are each made the same. Overall, the distance between the wall of the chamber and the plate-shaped elements thus decreases along the flow direction.
- the object on which the invention is based is to propose a device for distributing air, which makes it possible for substantially the same amount of air to emerge from the different air outlet openings in relation to different sides of the distributor.
- the invention achieves the object by a device for distributing air, which has at least one housing.
- the housing has an air inlet opening and several air outlet openings.
- at least in an interior of the housing arranged a displacer.
- the at least one displacement element has at least one (special or excellent) cutting plane.
- the sectional plane of the displacement element is designed as a sectional plane of a hollow cylinder expanding along a longitudinal axis of the housing.
- the widening is in particular conical.
- the expansion relates only to a part or section of the hollow cylinder.
- the device according to the invention for distributing air has a housing with at least one air inlet opening and a plurality of - so at least two - air outlet openings.
- the displacer element is designed in such a way that it has at least one cutting plane which corresponds to the sectional plane as it has a hollow cylinder which widens along the longitudinal axis.
- the displacement element is designed as a hollow cylinder.
- the displacer element is not rotationally symmetrical, but the displacer element has the mentioned sectional plane, whereby the sections of the hollow cylinder are widened by lateral walls to form spatial structures.
- the hollow cylinder has a circular cross section.
- the distribution of the air takes place within the interior of the housing, so that substantially the same amount of air emerges from the outlet openings on the different sides of the housing. If, for example, the air outlet is compared with one another from three sides, the displacer element results in each case in approximately one third of the air quantity which is introduced via the air inlet opening.
- the leaning of the displacer to the shape of a hollow cylinder causes the air in particular also flows through the Verdrticiane- relement.
- the at least one displacement element is spaced from an inner wall of the housing in such a way that air is circulated around the at least one displacement of the housing. drijnelement flows around. Between the displacement element - or especially its outside - and the inner wall of the housing, there is thus sufficient clearance in this embodiment, so that the air can flow around the displacement element.
- a plurality of displacement elements are present and that they are configured and arranged such that the air flows around them. The air is thus not only passed through the displacer element or possibly through a plurality of displacement elements, but the air also flows around it.
- the at least one displacement element is designed to be rotationally symmetrical.
- the rotational symmetry about a longitudinal axis of the housing is given, wherein the longitudinal axis preferably extends through the air inlet opening.
- one of the two aforementioned embodiments is accompanied by the fact that the displacement element essentially has the shape of a hollow cylinder which widens conically along a longitudinal axis of the housing.
- the cutting plane is enlarged rotationally symmetrical to a hollow cylinder.
- the at least one displacement element has at least two sections.
- a first portion has a substantially constant diameter and a second portion has a diameter increasing along the longitudinal axis.
- the diameter relates to the inner diameter and / or the outer diameter of the hollow cylinder.
- the first Section and the second section follow each other depending on the design of each other directly or indirectly.
- An embodiment includes that in the interior of the housing at least two displacement elements are present.
- the displacement elements are configured identically with respect to their basic geometric shape, so that the at least two displacement elements each have a sectional plane in the manner of a sectional plane of a conically widening hollow cylinder.
- the at least two displacement elements are arranged along the longitudinal axis so that they partially overlap. In this embodiment, the at least two displacement elements thus partially engage one another along the longitudinal axis.
- a plurality of displacement elements are present, which are all fixed statically in the housing. Due to the static fixation, a change in the displacer elements with respect to shape, orientation or positioning in the housing is thus not possible. In particular, no controller for a mechanical actuation or conversion of the displacer or the displacer elements is present.
- the at least two displacement elements are designed substantially the same.
- the displacement elements in one embodiment have the same basic shape or geometry, so that they have at least a similar appearance.
- the at least two displacement elements are configured and arranged in the interior of the housing such that the displacement elements are symmetrical-preferably rotationally symmetrical-about the longitudinal axis.
- the device and in particular the housing are designed symmetrically about the longitudinal axis.
- the housing is formed by two symmetrical housing shells.
- the at least two displacement elements have different end radii.
- the end radii are the radii of the respective end faces of the displacement elements with the largest cross-sectional area of the affected displacement element.
- the end radii decrease along the longitudinal axis of the housing, starting from the air inlet opening, so that, starting from the air inlet opening, the end radii of the displacer elements become smaller.
- the at least two displacement elements have different axial extensions.
- the displacement elements thus have different lengths in the axial direction.
- An alternative or additional embodiment consists in that the at least two displacement elements emanate from a common plane perpendicular to the longitudinal axis.
- the displacement elements take their respective beginning at the same height along the longitudinal axis of the housing.
- this embodiment is accompanied by the fact that the displacer elements have different input radii. This allows the air to also flow between the outside of a first displacer element and the inside of a second surrounding displacer element.
- the displacement elements have different axial extensions and / or different end radii.
- At least one air outlet opening allows the connection with a pipe for the further guidance of the air.
- the air outlet opening thus has, for example, a connection or a recess which allows a connection of a pipe.
- An embodiment includes that the air inlet opening with an air-emitting unit - in particular fluidically with respect to the air - is connectable.
- the air ejecting unit is in one embodiment a heater and in another embodiment is an air conditioner.
- the device has over at least one connection or connection point for a connection to a corresponding counterpart of the air-emitting unit.
- the device is a component of an air-emitting unit.
- the device is a part z.
- the housing has substantially the shape of a cube.
- the air inlet opening and the air outlet openings are located on the respective flat sides of the cube-shaped housing.
