Abstract

The invention concerns a method of manufacturing an air-heating enclosure, in particular enclosures intended for mounting on radiators or other water-heated bodies. A piece of at least partly perforated sheet metal is bent of folded to form a long-sided housing and one end clamped by means of a ring clamp or similar device to a ring holding a connection pipe on to an air-feed system. A height-adjustable compensation plate is inserted from the other (open) end of the housing into the inside of the housing against a cover, and this cover joined in turn to the housing by means of a ring clamp or similar device.

Description

Die Erfindung betrifft ein Verfahren zum Herstellen eines Quellauslasses, insbesondere für den Anbau unter Heizkörpern od. dgl. wasserführenden Kollektoren, sowie einen entsprechenden Quellauslaß.The invention relates to a method for producing a source outlet, in particular for mounting under radiators or the like. Water-carrying collectors, and a corresponding source outlet.

Unter Quellauslässen werden Auslässe für die Zuluft aus einem Luftleitsystem in einen Raum verstanden, wobei die Luft durch einen entsprechenden Anschlußstutzen in den Auslaß ein- und durch einen perforierten Gehäusemantel aus dem Auslaß in den Raum austritt. Quellauslässe haben die Aufgabe, Luft mit möglichst geringer Turbulenz und Induktion dem Raum zuzuführen.Source outlets are understood to be outlets for the supply air from an air guide system into a room, the air entering the outlet through a corresponding connecting piece and exiting the outlet through a perforated housing jacket. Source outlets have the task of supplying air to the room with the least possible turbulence and induction.

Derartige Quellauslässe sind z.B. in der EP-A-0 298 276 beschrieben.Such source outlets are e.g. in EP-A-0 298 276.

Dabei werfen Quellauslässe verschiedene Probleme auf. Zum einen ist wünschenswert, jedoch nur in seltenen Fällen erreichbar, daß die Zuluft mit einer gleichmäßigen Geschwindigkeit über die gesamte Austrittsfläche austritt und dies selbst bei einer höheren Zuluftgeschwindigkeit innerhalb des Luftleitsystems.Source outlets pose various problems. On the one hand, it is desirable, but can only be achieved in rare cases, that the supply air exits at a uniform speed over the entire outlet surface even at a higher supply air speed within the air control system.

Ferner ist ein relativ geringer Gesamtdruckverlust wünschenswert. Besonderes Augenmerk ist der Lautstärke zu widmen, mit welcher die Luft aus einem Quellauslaß austritt. Je höher und unregelmäßiger die Geschwindigkeit ist, desto größer ist auch die Lautstärke.Furthermore, a relatively small total pressure drop is desirable. Particular attention should be paid to the volume with which the air exits a source outlet. The higher and more irregular the speed, the greater the volume.

Probleme ergeben sich vor allem bei der Herstellung dieser Quellauslässe, da recht viele Schweißarbeiten zu erledigen sind.Problems arise especially in the manufacture of these source outlets, since quite a lot of welding work has to be done.

Der Erfinder hat sich zum Ziel gesetzt, ein Verfahren der o.g. Art zu entwickeln, mit dem ein Quellauslaß auf einfachem, kostengünstigem und umweltfreundlichem Wege hergestellt wird, wobei dieser Quellauslaß aber gerade die Anforderungen an eine Vergleichmäßigung der Luftverteilung und geringe Geräuschentwicklung erfüllt.The inventor set himself the goal of using a method of the above. To develop a way to produce a source outlet in a simple, inexpensive and environmentally friendly way, but this source outlet meets the requirements for uniform air distribution and low noise.

Zur Lösung dieser Aufgabe führt, daß ein Stück Blech zumindest teilweise perforiert, zu einem langgestreckten Gehäuse gebogen oder abgekantet und an einem offenen Ende über einen Klemmring od. dgl. mit einem Anschlußstutzen an ein Luftleitsystem haltenden Deckelring verbunden wird und daß von dem anderen offenen Ende des Gehäuses her in das Innere ein höhenverstellbares Ausgleichsblech an einem Deckel eingeschoben und dieser mit dem Gehäuse wiederum über einen Klemmring od. dgl. verbunden wird, wobei vor dem Einschieben in das Ausgleichsblech Schlitzungen eingestanzt werden.To achieve this object, a piece of sheet metal is at least partially perforated, bent or bent to form an elongated housing and connected at one open end via a clamping ring or the like of the housing, a height-adjustable compensating plate is pushed into the interior of a cover and this is in turn connected to the housing by means of a clamping ring or the like. Slits are punched into the compensating plate before being inserted.

Die Lösung der Aufgabe hinsichtlich des Quellauslässes ist Gegenstand des Patentanspruch 4.The solution to the problem with regard to the source outlet is the subject of claim 4.

Bei dieser Herstellung muß weder gepunktet noch geschweißt werden. D.h. es findet keine Umweltbeeinträchtigung statt, die immer bei Schweißvorgängen von Zinkblech erfolgt. Ferner wird Energie in hohem Maße eingespart. Das gesamte Verfahren ist schnell und rationell. Ferner entsteht ein Quellauslaß, welcher sich in der Praxis hervorragend bewährt hat.With this production, there is no need to spot or weld. I.e. there is no environmental impact that always occurs during the welding of zinc sheet. Energy is also saved to a great extent. The whole process is quick and efficient. Furthermore, a source outlet is created, which has proven itself extremely well in practice.

Bevor das Ausgleichblech in das Gehäuse des Quellauslasses eingeschoben wird, sollen Schlitzungen eingestanzt werden, die der Vergleichmäßigung des Luftstromes dienen. Bevorzugt entstehen diese Schlitzungen beim Ausbiegen von angestanzten Leitstegen. Diese Leitstege werden dann etwa senkrecht nach oben ausgebogen und dienen zur Führung der Zuluft.Before the compensating plate is pushed into the housing of the source outlet, slits should be punched in, which serve to even out the air flow. These slits preferably arise when bending-out guide webs. These guide bars are then bent approximately vertically upwards and serve to guide the supply air.

Im vorliegenden hat sich der Erfinder noch etwas Besonderes einfallen lassen. Erfindungsgemäß sollen die freien Enden der Leitstege abgekantet werden, so daß Querstege geringerer Breite entstehen. Hierdurch wird gleichzeitig der gesamte Luftführungsschlitz innerhalb des Ausgleichblechs verengt, so daß ein gewisser Luftstau stattfindet. Dieser Stau bewirkt zum einen eine Vergleichmäßigung der Luftströmung über die gesamte Fläche des Ausgleichblechs, ferner wird aber auch eine geringe Induktionszone geschaffen, welche bewirkt, daß die Zuluft etwas beschleunigt an dem Heizkörper bzw. dergleichen Kollektoren entlangstreicht und ein Temperaturaustausch relativ schnell stattfindet.In the present, the inventor has come up with something special. According to the invention, the free ends of the guide webs are to be folded, so that transverse webs of smaller width are created. As a result, the entire air guiding slot within the compensating plate is narrowed at the same time, so that a certain air jam takes place. This congestion on the one hand causes an equalization of the air flow over the entire surface of the compensating plate, but also creates a small induction zone, which causes the supply air to sweep along the heating element or similar collectors somewhat accelerated and a temperature exchange takes place relatively quickly.

Ein entsprechender Quellauslaß besteht somit aus einem zumindest teilweise perforierten langgestreckten Gehäuse, welches beidseits durch Deckel bzw. einen Deckelring mit eingelassenem Anschlußstutzen an ein Luftleitsystem abgedeckt ist. Im Inneren des Gehäuses befindet sich das oben beschriebene Ausgleichblech.A corresponding source outlet thus consists of an at least partially perforated elongated housing, which is covered on both sides by a cover or a cover ring with a recessed connecting piece to an air duct system. The compensation plate described above is located inside the housing.

Nach der Erfindung ist dieses Ausgleichblech höhenverstellbar. Der Einfachheit halber kann hierzu ein Gewindebolzen verwendet werden, welcher beispielsweise an dem DecKel festliegt. Mit seinem Gewindeabschnitt greift er in eine entsprechende Befestigungslasche bzw. in ein dort vorgesehenes Bohrloch mit Innengewinde ein, wobei er dieses Innengewinde kämmt. Beim Drehen des Gewindebolzens wandert somit die Befestigungslasche und somit auch das gesamte Ausgleichblech entlang dem Gewindeabschnitt, wodurch die Lage des Ausgleichbleches verändert wird. Hierdurch kann aber wiederum die Menge derjenigen Zuluft beschleunigt werden, welche gezwungenermaßen durch das Ausgleichblech geführt wird. Ist diese Zuluft relativ gering, so entsteht auch nur eine äußerst geringe Induktionszone. Die übrige Luft überstreicht dann das Ausgleichblech und gelangt direkt durch den perforierten Gehäusemantel zum Heizkörper. Je mehr das Ausgleichblech angehoben wird, um so mehr Zuluft muß gezwungenermaßen durch das Ausgleichblech strömen, weshalb die Induktionszone verstärkt wird. Hierdurch kann jedem Wunsch Rechnung getragen werden.According to the invention, this compensating plate is adjustable in height. For the sake of simplicity, a threaded bolt can be used for this purpose, which is fixed, for example, to the DecKel. With its threaded section, it engages in a corresponding fastening lug or in a drill hole provided there with an internal thread, whereby it combs this internal thread. When the threaded bolt is turned, the fastening tab and thus the entire compensating plate move along the threaded section, as a result of which the position of the compensating plate is changed. This, however, can in turn accelerate the amount of supply air that is forced through the compensating plate. If this supply air is relatively low, there is only an extremely small induction zone. The remaining air then sweeps over the compensating plate and reaches the radiator directly through the perforated casing. The more the compensating plate is raised, the more supply air is forced to flow through the compensating plate, which is why the induction zone is reinforced. In this way, every wish can be taken into account.

Further advantages, features and details of the invention result from the following description of preferred exemplary embodiments and from the drawing; this shows in
Figure 1

Ein erfindungsgemäßer Quellauslaß R besteht aus einem Gehäuse 1, welches querschnittlich rund, ellipsenförmig oder eckig geformt sein kann. Bevorzugt wird dieses Gehäuse 1 durch Biegen bzw. Kanten aus einem einzigen Stück Blech hergestellt. Eine Oberseite 2 und ggfs. auch eine Frontseite 3 des Gehäuses 1 können perforiert sein. Die Perforation erzeugt Löcher 4, deren Abstände bzw. Durchmesser je nach Wunsch gewählt sein können. Die linksseitige Öffnung des langgestreckten Gehäuses 1 ist von einem Deckelring 5 abgedeckt, welcher einen Anschlußstutzen 6 an ein nicht näher gezeigtes Luftleitsystem umfängt. Hierzu ist in den Anschlußstutzen 6 eine entsprechende Ringnut 7 eingeformt, in welche der Deckelring 5 eingreift. Der Deckelring 5 selbst schlägt dann zusammen mit dem Anschlußstutzen 6 an eine Randkante des Gehäuses 1 an und kann dort beispielsweise durch einen Klemmring 8 od. dgl. gehalten werden.A source outlet R according to the invention consists of a housing 1, which can be round, elliptical or angular in cross section. This housing 1 is preferably produced by bending or edging from a single piece of sheet metal. A top side 2 and possibly also a front side 3 of the housing 1 can be perforated. The perforation creates holes 4, the spacing or diameter of which can be selected as desired. The left-hand opening of the elongated housing 1 is covered by a cover ring 5, which encloses a connecting piece 6 to an air guide system, not shown in detail. For this purpose, a corresponding annular groove 7 is formed in the connecting piece 6, in which the cover ring 5 engages. The cover ring 5 itself then strikes together with the connecting piece 6 on an edge of the housing 1 and can be held there for example by a clamping ring 8 or the like.

Von der dem Anschlußstutzen 6 gegenüberliegenden Seite her wird in das Innere I des Gehäuses 1 ein Ausgleichblech 9 eingeschoben. Dieses Ausgleichblech 9 besitzt eine Verbindungslasche 10, welche von einem Gewindebolzen 11 durchsetzt ist. Dieser Gewindebolzen 11 wird von einem Befestigungswinkel 12 od. dgl. an einem Deckel 13 gehalten, wobei dieser Deckel 13 wiederum über einen entsprechenden Klemmring 14 mit dem Gehäuse 1 verbunden ist.A compensating plate 9 is inserted into the interior I of the housing 1 from the side opposite the connecting piece 6. This compensating plate 9 has a connecting tab 10, which is penetrated by a threaded bolt 11. This threaded bolt 11 is held by a fastening bracket 12 or the like on a cover 13, this cover 13 in turn being connected to the housing 1 via a corresponding clamping ring 14.

Der Gewindebolzen 11 ist von außen her zugänglich, wobei er einen Schlitz 15 zum Eingriff eines Schraubenziehers aufweist. Beim Drehen des Gewindebolzens 11 bleibt dieser ortsfest im Befestigungswinkel 12, jedoch wandert das Ausgleichblech 9 in Richtung x im Inneren I des Gehäuses 1. Hierdurch erfolgt eine Höhenverstellung des Ausgleichblechs 9.The threaded bolt 11 is accessible from the outside, wherein it has a slot 15 for the engagement of a screwdriver. When the threaded bolt 11 is turned, it remains stationary in the fastening bracket 12, but the compensating plate 9 moves in the direction x in the interior I of the housing 1. This causes the compensating plate 9 to be adjusted in height.

Das Ausgleichblech 9 besitzt einen umlaufenden Rahmen 16, welcher eine Platte 17 umgibt. Diese Platte 17 besitzt nicht näher gezeigte Querschlitze, durch welche die vom Anschlußstutzen 6 her eingeführte Luft zu der perforierten Oberseite 2 gelangen kann. Geleitet wird die Luft mittels etwa senkrecht zu der Platte 17 aufstehenden Leitstegen 18, welche in einem Abstand von etwa 20mm angeordnet sind. Bevorzugt erfolgt die Ausbildung der Leitstege 18 beim Ausstanzen der Schlitzungen in der Platte selbst, wobei die Leitstege nach der Erzeugung entsprechender Stanzlinien aus der Platte 17 ausgebogen werden.The compensating plate 9 has a peripheral frame 16 which surrounds a plate 17. This plate 17 has transverse slots, not shown, through which the air introduced from the connecting piece 6 can reach the perforated upper side 2. The air is directed by means of guide webs 18 which are approximately perpendicular to the plate 17 and which are arranged at a distance of approximately 20 mm. The guide webs 18 are preferably formed when the slits are punched out in the plate itself, the guide webs being bent out of the plate 17 after corresponding punching lines have been produced.

Vom freien Ende der Leitstege 18 sind noch kurze Querstege 19 abgekantet, welche etwa 5-6mm breit sind. Hierdurch wird der dann erzeugte freie Schlitz 20 zwischen zwei Querstege 19 verkleinert. D.h., die Breite b des Schlitzes 20 ist kleiner als die Breite a der Plattenschlitzung 21. Hierdurch wird für die Zuluft ein gewisser Vordruck erreicht und somit eine leichte Induktionszone geschaffen. Diese ermöglicht es, daß die Zuluft trotz einem langsamen Ausströmen nach der Induktionszone den Temperaturunterschied zu einem nicht näher gezeigten Heizkörper hin relativ schnell abbaut.Short transverse webs 19, which are approximately 5-6 mm wide, are also folded from the free end of the guide webs 18. As a result, the free slot 20 then generated between two transverse webs 19 is reduced. In other words, the width b of the slot 20 is smaller than the width a of the plate slot 21. This achieves a certain pre-pressure for the supply air and thus creates a slight induction zone. This enables the supply air to reduce the temperature difference to a radiator (not shown in detail) relatively quickly despite a slow outflow to the induction zone.

Eine Verstellung des Ausgleichblechs 9 in der Höhe, d.h. in Richtung x, bietet die Möglichkeit der Veränderung dieser Induktionszone je nach gewünschter Strömungsgeschwindigkeit und Luftmenge. Wird beispielsweise das Ausgleichblech 9 abgesenkt, so vermindert sich die Menge der Luft, welche durch die Schlitzungen 21 bzw. 22 des Ausgleichblechs 9 strömt. Hierdurch wird auch die Luftmenge vermindert, welche eine Induktionszone schafft. Die Einstellung ist mittels des Gewindebolzens 11 äußerst einfach.An adjustment of the compensating plate 9 in height, i.e. in direction x, offers the possibility of changing this induction zone depending on the desired flow rate and amount of air. If, for example, the compensating plate 9 is lowered, the amount of air flowing through the slots 21 or 22 of the compensating plate 9 is reduced. This also reduces the amount of air that an induction zone creates. The setting is extremely simple by means of the threaded bolt 11.

Sowohl die Herstellung des Ausgleichblechs wie auch des Gehäuses und der restlichen Teile des Quellauslasses geschieht sauber und schnell. Es braucht weder gepunktet noch geschweißt zu werden, d.h. es wird Energie eingespart und die Umwelt weniger belastet, wie dies bei Schweißvorgängen von Zinkblech bekanntermaßen geschieht. Auch das Montieren ist äußerst einfach und kann schnell bewerkstelligt werden.The production of the compensating plate as well as the housing and the remaining parts of the source outlet is done cleanly and quickly. It does not need to be spotted or welded, i.e. energy is saved and the environment is less polluted, as is known to be the case when welding zinc sheet. Mounting is also extremely easy and can be done quickly.
