Abstract

An opening (9) is provided at the bottom end of an inner tube (8) running from top to bottom inside one of the vertical distribution tubes (3, 4) for the heating medium. The opening links the inside of the inner tube with the horizontal radiator tube (5) extending between the inlet and outlet connections (6, 7) for the heating medium. A partition wall (10) extends between the inner tube and the vertical distribution tube above the opening, sealing off a space (11) around this opening from the rest of heating medium.

Description

Röhrenheizkörper mit mehreren übereinander angeordneten waagerechten Rohren, die mit ihren Enden zu beiden Seiten an senkrechten Verteilerrohren angeschlossen sind, wobei an einem waagerechten Rohr, insbesondere am untersten Rohr, der Vor- und Rücklaufanschluß befestigt ist und eine der seitlichen senkrechten Verteilerrohre ein inneres Rohr aufweist, daß sich vom unteren Ende des Verteilerrohres bis zum oberen Ende erstreckt und mit einem der Anschlüsse in Verbindung steht.Tubular radiator with several superimposed horizontal pipes with their ends on either side vertical manifolds are connected, being at one horizontal pipe, especially on the lowest pipe, the front and Return port is attached and one of the side vertical Distribution pipes has an inner tube that extends from the lower End of the manifold extends to the top and with one of the connections is connected.

Meistens werden aus praktischen und ästhetischen Gründen Vorlauf und Rücklauf unten an die Verteilerrohre angeschlossen. Hierbei strömt die Heizflüssigkeit jedoch im wesentlichen nur durch die unteren und oberen waagerechten Röhren und weniger durch die mittleren waagerechten Röhren. Die Temperatur der im Heizkörper nach oben strömenden Heizflüssigkeit nimmt dadurch ab, daß diese Heizflüssigkeit sich mit der kälteren Heizflüssigkeit vermischt, die aus den mittleren Röhren wegströmt. Hieraus resultiert eine ungleichmäßige Erwärmung und ein nur geringer Wirkungsgrad (Leistung).Mostly for practical and aesthetic reasons Flow and return connected at the bottom to the distribution pipes. Here, however, the heating liquid essentially only flows through the lower and upper horizontal tubes and less through the middle horizontal tubes. The temperature of the This causes the radiator to flow upwards that this heating fluid with the colder Heating fluid mixed up from the middle tubes flows away. This results in uneven heating and an only low efficiency (performance).

Es ist bekannt in einem der senkrechten Verteilerrohre ein inneres Rohr einzusetzen, wobei das untere Ende des Rohres direkt an dem Vorlaufanschluß angeschlossen ist. Das innere Rohr endet bei dieser Konstruktion in einem oberen Bereich des Heizkörpers, um zu erreichen, daß die durch den Vorlauf eingeleitete Heizflüssigkeit erst in diesem oberen Bereich in das eigentliche Volumen des Heizkörpers eintritt. Hierdurch ist gewährleistet, daß auch bei einem Röhrenheizkörper mit unten angeordnetem Vor- und Rücklaufanschlüssen die Fließrichtung im Heizkörper von oben nach unten und damit, so wie bei einem Diagonal-Anschluß, entgegen der natürlichen Fließrichtung der Heizflüssigkeit ist.It is known in one of the vertical manifolds insert inner tube with the lower end of the tube is connected directly to the flow connection. The inner In this construction, the pipe ends in an upper region of the Radiator to achieve that through the lead introduced heating liquid only in this upper area the actual volume of the radiator occurs. This is ensures that even with a tubular radiator with the bottom arranged flow and return connections the flow direction in Radiators from top to bottom and thus, just like one Diagonal connection, against the natural flow direction of the Heating fluid is.

Ein derartiger Röhrenheizkörper hat jedoch den Nachteil, daß durch das innere Rohr in einem der senkrechten Verteilerrohre die Position des Vorlaufanschlusses, der direkt in das innere Rohr mündet, festgelegt ist. Bei einer derartigen Konstruktion ist es daher nicht möglich, die Position der unteren Vor- und Rücklaufanschlüsse variabel zu gestalten, um z.B. speziellen Design-Anforderungen gerecht zu werden.However, such a tubular heater has the disadvantage that through the inner tube in one of the vertical manifolds the position of the flow connector that goes directly into the inner Pipe opens, is fixed. With such a construction it is therefore not possible to change the position of the lower and To design return connections variably, e.g. special To meet design requirements.

Es sind andere Röhrenheizkörper bekannt, bei denen zwar die unteren Vor- und Rücklaufanschlüsse an einer beliebigen Position eines unteren waagerechten Rohres angebracht sind, jedoch ist es bei einen solchen Röhrenheizkörper nicht möglich, die durch den Vorlauf eingeleitete Heizflüssigkeit durch ein inneres Rohr eines der seitlichen Verteilerrohre bis in einen oberen Bereich des Heizkörper zu leiten. Bei derartigen Heizkörpern erfolgt demnach die Einleitung der Heizflüssigkeit in der natürlichen Fließrichtung mit den obengenannten Nachteilen.Other tubular radiators are known, in which the lower flow and return connections on any Position of a lower horizontal pipe are attached, however, with such a tubular heater, it is not possible the heating fluid introduced by the flow through a inner pipe of one of the side distribution pipes into one to direct the upper area of the radiator. With such Radiators are therefore charged with the heating fluid in the natural flow direction with the above Disadvantages.

Aufgabe der Erfindung ist es, einen Heizkörper der eingangs genannten Art so zu verbessern, daß bei einfacher Herstellung und Montage die Position der Vor- und Rücklaufanschlüsse an einem unteren Anschlußrohr des Heizkörpers variabel ausgelegt werden kann und trotzdem die Heizflüssigkeit so in das Volumen des Heizkörpers eintritt, daß die Fließrichtung im Heizkörper von oben nach unten entgegen der natürlichen Fließrichtung der Heizflüssigkeit ist, wodurch ein hoher Wirkungsgrad und eine gleichmäßige Erwärmung erreicht wird.The object of the invention is a radiator of the beginning to improve the type mentioned so that with simple manufacture and mounting the position of the supply and return connections a lower connecting pipe of the radiator designed variably can be and still the heating liquid in the volume of the radiator occurs that the flow direction in the radiator from top to bottom against the natural flow direction of the Heating fluid is, which means a high efficiency and a uniform heating is achieved.

Diese Aufgabe wird erfindungsgemäß dadurch gelöst, daß das innere Rohr in einem unterer. Bereich eine im Rohrmantel angeordnete Öffnung aufweist, durch die das Innere des inneren Rohres mit dem Anschlußrohr verbunden ist, und daß sich zwischen dem inneren Rohr und dem Verteilerrohr oberhalb der genannten Öffnung eine Trennwand erstreckt, die den die Öffnung umgebenden Raum gegenüber dem restlichen Heizkörpervolumen abdichtet.This object is achieved in that the inner tube in a lower one. Area one in the pipe jacket arranged opening through which the interior of the inner Tube is connected to the connecting pipe, and that itself between the inner pipe and the distributor pipe above the called opening extends a partition that the opening surrounding space compared to the remaining radiator volume seals.

Durch die Konstruktion des erfindungsgemäßen Röhrenheizkörpers ist es möglich, die aufgeheizte Heizflüssigkeit an einer beliebigen Position in ein unteres waagerechtes Anschlußrohr einzuleiten, wobei die Heizflüssigkeit vom dem waagerechten Anschlußrohr ausgehend durch die Öffnung in das innere Rohr hineinströmt und durch dieses innere Rohr bis in einen oberen Bereich des Heizkörpers geleitet wird, wo es erst in das eigentliche Heizkörpervolumen eintritt.By the construction of the tubular heater according to the invention it is possible to use the heated heating fluid on a any position in a lower horizontal connection pipe initiate, the heating fluid from the horizontal Connection pipe starting through the opening in the inner pipe flows in and through this inner tube into an upper one Area of the radiator, where it is only in the actual radiator volume occurs.

Die zwischen dem inneren Rohr und dem Verteilerrohr oberhalb der genannten Öffnung angeordnete Trennwand ist vorgesehen, damit die Heizflüssigkeit auf jeden Fall immer durch die Öffnung im inneren Rohr in dieses Rohr hineintritt und sich somit nicht schon in einem unteren Bereich des Verteilerrohres auf die Vielzahl der waagerechten Rohre aufteilt. Durch die Trennwand, die z.B. ringfförmig das inneren Rohr umgeben kann, wird im unteren Bereich des Verteilerrohres ein die Öffnung umgebender Raum gebildet, der gegenüber dem restlichen Heizkörpervolumen abgedichtet ist.The one between the inner pipe and the manifold above the partition arranged above said opening is provided, so that the heating fluid is always through the Opening in the inner tube enters this tube and itself therefore not already in a lower area of the distributor pipe divided over the multitude of horizontal pipes. Through the Partition which e.g. can surround the inner tube in a ring shape, the opening is in the lower area of the distributor pipe surrounding space formed, that of the rest Radiator volume is sealed.

Wenn die Vor- und Rücklaufanschlüsse an demselben unteren waagerechten Anschlußrohr des Heizkörpers angeordnet sind, ist es sehr vorteilhaft wenn zwischen den Anschlüssen der Durchfluß im Anschlußrohr unterbrochen ist. Hierdurch wird verhindert, daß die Heizflüssigkeit direkt von dem Vorlauf zum Rücklaufanschluß strömt, ohne in das eigentliche Heizkörpervolumen eingeleitet zu werden.If the flow and return connections on the same lower horizontal connecting pipe of the radiator are arranged it is very advantageous if the flow between the connections is interrupted in the connecting pipe. This prevents that the heating fluid directly from the flow to Return port flows without going into the real thing Radiator volume to be initiated.

Ohne eine derartige Durchflußunterbrechung wäre demnach die Funktion des Heizkörpers nicht gesichert. Die Unterbrechung des Durchflusses zwischen den beiden Anschlüssen kann beispielsweise durch einen Stopfen im Rohr oder eine Verengung im Rohr erfolgen. Die Verengung kann insbesondere auch aus einer Rohrzusammenquetschung bestehen.Without such a flow interruption, the would be Function of the radiator not secured. The interruption of the Flow between the two connections can for example by a plug in the pipe or a constriction done in the tube. The narrowing can in particular also result from a pipe crush exist.

Es wird als vorteilhaft empfunden, wenn im unteren Bereich wenigstens des Verteilerrohres in dem sich das innere Rohr befindet eine Muffe einliegt, durch die hindurch das innere Rohr in den Heizkörper einschiebbar ist. Durch diese Konstruktion ist es möglich, daß innere Rohr beispielsweise zu Wartungszwecken aus dem Heizkörper zu entfernen. Eine solche Notwendigkeit zur Wartung kann z.B. dann entstehen, wenn sich die Öffnung im Rohrmantel des inneren Rohres oder auch der gesamte die Öffnung umgebenden Raum zum Beispiel durch Schwebstoffe in der Heizflüssigkeit zugesetzt hat, wodurch die Funktion des Heizkörpers eingeschränkt ist.It is felt to be beneficial if in the lower range at least the manifold in which the inner tube is a sleeve, through which the inner Tube can be inserted into the radiator. Through this Construction, it is possible that the inner tube, for example Remove maintenance from the radiator. Such The need for maintenance can e.g. then arise when the opening in the tube jacket of the inner tube or the entire space surrounding the opening, for example Suspended suspended matter in the heating fluid, causing the Function of the radiator is restricted.

Weiterhin ist es sinnvoll, daß die Muffe ein Innengewinde aufweist, in das ein Stopfen eindrehbar ist, wobei mit dem Stopfen das innere Rohr in dem Verteilerrohr befestigbar und das Verteilerrohr gleichzeitig nach außen abdichtbar ist. Es ist zu erwähnen, daß nicht nur das Verteilerrohr mit dem inneren Rohr sondern auch das andere senkrechte Verteilerrohr eine derartige Muffe mit Innengewinde aufweisen kann. Hierdurch ist dann z.B. die Möglichkeit gegeben, beispielsweise zu Wartungszwecken von dem Heizkörper die Heizflüssigkeit abzulassen, ohne den gesamten Heizkreislauf lüften zu müssen.It also makes sense that the sleeve has an internal thread has, into which a stopper can be screwed, with the Plug the inner tube into the manifold and attachable the manifold can be sealed to the outside at the same time. It it should be mentioned that not only the manifold with the inner tube but also the other vertical manifold can have such a sleeve with an internal thread. hereby is then e.g. given the opportunity, for example, to Maintenance purposes from the radiator to the heating fluid drain without having to ventilate the entire heating circuit.

Die Funktion des Röhrenheizkörpers wird dadurch gewährleistet, daß die durch den Vorlaufanschluß eingeleitete Heizflüssigkeit durch das Anschlußrohr des Heizkörpers in den die Öffnung des inneren Rohres umgebenden Raumes einleitbar ist, der gegenüber dem restlichen Heizkörpervolumen durch die Trennwand abgedichtet ist. Von diesem die Öffnung umgebenden Raum ist die Heizflüssigkeit durch die Öffnung und das innere Rohr bis in den oberen Bereich des genannten Verteilerrohres leitbar. Erst in diesem oberen Bereich des Heizkörpers tritt die Heizflüssigkeit in das eigentliche Volumen des Heizkörpers ein und heizt diesen auf. Nach einer Abkühlung sinkt die Heizflüssigkeit automatisch bis in einen unteren Bereich des Heizkörpers und verläßt diesen Bereich dann wieder durch den Rücklaufanschluß.The function of the tubular heater is guaranteed that the heating fluid introduced through the flow connection through the connecting pipe of the radiator in the opening of the inner tube surrounding space can be introduced, the opposite the remaining radiator volume through the partition is sealed. Of this space surrounding the opening is the Heating fluid through the opening and the inner tube up to the upper area of said manifold is conductive. First in this upper area of the radiator Heating fluid into the actual volume of the radiator and heats it up. After cooling, the sinks Heating fluid automatically into a lower area of the Radiator and then leaves this area again through the Return connection.

Es soll erwähnt werden, daß sich die Erfindung nicht ausschließlich auf die hier beschriebene Fließrichtung der Heizflüssigkeit beschränkt. So ist es auch denkbar, die Fließrichtung in dem Heizkörper umzudrehen.It should be noted that the invention is not exclusively to the flow direction described here Heating fluid limited. So it is also conceivable that Reverse flow direction in the radiator.

Ein Ausführungsbeispiel der Erfindung ist in den Zeichnungen dargestellt und wird im folgenden näher beschrieben.An embodiment of the invention is in the drawings shown and is described in more detail below.

Das innere Rohr (8) hat eine im unteren Bereich im Rohrmantel angeordnete Öffnung (9), durch die das Innere des inneren Rohres (8) mit dem Anschlußrohr (5) verbunden ist. Weiterhin ist in dem unteren Bereich des Verteilerrohres oberhalb der Öffnung (9) zwischen dem inneren Rohr (8) und dem Verteilerrohr (4) eine ringförmige Trennwand (10) angebracht, die den die Öffnung (9) umgebenden Raum (11) gegenüber dem restlichen Heizkörpervolumen abdichtet. The inner tube (8) has one in the lower area in the tube jacket arranged opening (9) through which the interior of the interior Tube (8) is connected to the connecting tube (5). Farther is in the lower area of the distributor pipe above the Opening (9) between the inner pipe (8) and the distributor pipe (4) an annular partition (10) attached to the Opening (9) surrounding space (11) opposite the rest Seals radiator volume.

Weiterhin ist zwischen dem Vorlaufanschluß (6) und dem Rücklaufanschluß (7) innerhalb des Anschlußrohres eine Trennwand (14) eingezogen, um zwischen diesen beiden Anschlüssen den Durchfluß im Rohr zu unterbrechen. Die Durchflußunterbrechung an dieser Stelle könnte auch durch einen Stopfen, durch eine Rohreinquetschung oder andere Mittel realisiert sein.Furthermore, between the flow connection (6) and the Return connection (7) within the connecting pipe Partition (14) retracted to between these two Connections to interrupt the flow in the pipe. The Flow interruption at this point could also be caused by a Stopper, by pipe pinching or other means be realized.

Die Figur 2 zeigt im Detail den unteren Bereich des rechten Verteilerrohres (4), welches das innere Rohr (8) enthält. Hier ist eine Muffe (12) zu erkennen, die im unteren Ende des Verteilerrohres (4) einliegt. Durch diese Muffe hindurch ist das innere Rohr (8) in den Heizkörper (1) einschiebbar. Die Muffe (12) weist ein Innengewinde (13) auf, in das ein Stopfen (16) eindrehbar ist, wobei mit dem Stopfen (16) das innere Rohr (8) in dem Verteilerrohr (4) befestigbar und gleichzeitig das Verteilerrohr (4) nach außen hin insbesondere mit einem zusätzlichen Dichtring (17), abdichtbar ist.Figure 2 shows in detail the lower area of the right Distribution pipe (4), which contains the inner tube (8). Here a sleeve (12) can be seen in the lower end of the Distribution pipe (4) lies. Is through this sleeve the inner tube (8) can be inserted into the radiator (1). The The sleeve (12) has an internal thread (13) into which a plug (16) can be screwed in, with the plug (16) the inner tube (8) can be fastened in the distributor pipe (4) and at the same time that Distribution pipe (4) towards the outside, in particular with a additional sealing ring (17), is sealable.

In diesem Ausführungsbeispiel kann das links angeordnete Verteilerrohr (3) ebenfalls eine Muffe (12) und eine Trennwand (10) aufweisen, es beinhaltet jedoch kein inneres Rohr. Ein inneres Rohr (8) ist jedoch dann alternativ auch im linken Verteilerrohr einsetzbar, wodurch die Vor- und Rücklauffunktion der Anschlüsse (6) und (7) untereinander austauschbar ist.In this embodiment, the one on the left Distribution pipe (3) also a sleeve (12) and a partition (10), but it does not include an inner tube. On inner tube (8) is then alternatively in the left Distribution pipe can be used, which means the forward and return function the connections (6) and (7) are interchangeable.

Zwischen dem oberen Ende der Muffe (12) und der Trennwand (10), die sich zwischen dem inneren Rohr (8) und dem Verteilerrohr (4) erstreckt, befindet sich eine Öffnung (9) in dem Mantel des inneren Rohres. Durch diese Öffnung kann Heizflüssigkeit in das innere Rohr eintreten und wird somit bis in den oberen Bereich des Heizkörpers geleitet.Between the upper end of the sleeve (12) and the partition (10), which is between the inner tube (8) and the manifold (4) extends, there is an opening (9) in the jacket of the inner tube. Through this opening, heating fluid can enter inner tube enter and is thus up to the upper area of the radiator.

Die Fließrichtung der Heizflüssigkeit ist durch die eingezeichneten Pfeile angegeben. Durch den Vorlaufanschluß 6 tritt aufgeheizte Heizflüssigkeit in das untere Anschlußrohr (5) ein, wobei es durch die zwischen den Anschlüssen angeordnete Trennwand (14) daran gehindert wird, direkt durch den Rücklaufanschluß (7) zurückzuströmen. Die Heizflüsssigkeit fließt sodann in Pfeilrichtung durch das Anschlußrohr (5) bis in den die Öffnung des inneren Rohres umgebenden Raum (11), der durch die Trennwand (10) von dem übrigen Heizkörpervolumen abgegrenzt ist.The direction of flow of the heating fluid is through the indicated arrows. Through the flow connection 6 heated heating fluid enters the lower connection pipe (5) one, passing through between the connectors arranged partition (14) is prevented directly by to flow back the return connection (7). The heating liquid then flows in the direction of the arrow through the connecting pipe (5) to into the space (11) surrounding the opening of the inner tube, the through the partition (10) from the remaining radiator volume is delimited.

Innerhalb dieses Umgebungsraumes fließt die Heizflüssigkeit nach oben und tritt dabei durch die Öffnung (9) in das innere Rohr (8) ein. Anschließend fließt die Heizflüssigkeit in Pfeilrichtung nach oben bis in den oberen Bereich des Heizkörpers (1). Die anhand der Pfeile angegeben Fließrichtung ist hier nur beispielhaft angegeben. Es ist ebenso denkbar, daß die Fließrichtung umgekehrt wird.The heating fluid flows within this surrounding space upwards and enters the interior through the opening (9) Tube (8). Then the heating fluid flows in Arrow direction up to the upper area of the Radiator (1). The flow direction indicated by the arrows is only given here as an example. It is also conceivable that the flow direction is reversed.

Das innere Rohr (8), das durch die Muffe (12) in den Heizkörper einschiebbar ist, zeigt am unteren Ende einen Kragen (15), mit dem es in der Muffe (12) zur Anlage kommt. Durch ein in die Muffe eingedrehten und hier nicht dargestellten Stopfen ist das innere Rohr (8) im Heizkörper (1) befestigbar. Gleichzeitig dichtet der Stopfen, der das innere Rohr (8) in Position hält das Verteilerrohr (4), bzw. den gesamten Heizkörper nach außen hin ab.The inner tube (8) through the sleeve (12) in the radiator can be inserted, shows a collar (15) at the lower end which comes to rest in the sleeve (12). By one in the This is the screwed plug and not shown here inner tube (8) can be fastened in the radiator (1). simultaneously seals the plug that holds the inner tube (8) in position the manifold (4), or the entire radiator to the outside down.

Durch die Muffe (12) ist es möglich, das mit der Bohrung (9) versehene innere Rohr (8) gegen ein inneres Rohr ohne Bohrung auszutauschen, wobei es dann auch möglich ist, die Muffe (12) als Vorlaufanschluß des Heizkörpers zu benutzen.Through the sleeve (12) it is possible to connect the hole (9) provided inner tube (8) against an inner tube without a bore exchange, it then also being possible to replace the sleeve (12) to use as a flow connection of the radiator.

Ein Röhrenheizkörper gemäß der Erfindung weist demnach eine größtmögliche Flexibilität bezüglich der Positionierung der Vor- und Rücklaufanschlüsse auf.A tubular heater according to the invention accordingly has one greatest possible flexibility regarding the positioning of the Flow and return connections on.
