Description

Die Erfindung betrifft einen Gliederradiator, insbesondere einen aus Aluminium gefertigten Gliederradiator, mit einer oberen Sammlerleiste für den Heizungsvorlauf sowie mit einer unteren Sammlerleiste für den Heizungsrücklauf und mit zwischen den beiden Sammlerleisten angeordneten sowie mit diesen mittels Rohrstücken verbundenen Radiatorgliedern, wobei die Rohrstücke entweder in den Bohrungen der Radiatorglieder und bzw. oder in Bohrungen der Sammlerleisten verschiebbar gehalten sind, sowie die beiden Sammlerleisten miteinander mittels Zugstangen verbunden sind. Derartige aus Aluminium gefertigte Gliederradiatoren sind deshalb vorteilhaft, da einerseits die Sammlerleisten und andererseits die Radiatorglieder aus stranggepreßten Profilstücken bestehen, weswegen sie in ihrer Herstellung relativ billig sind.The invention relates to a sectional radiator, in particular a sectional radiator made of aluminum, with an upper header for the heating flow as well as with a lower header for the heating return and with radiator members arranged between the two header bars and connected to them by means of pipe pieces, the pipe pieces either in the holes the radiator members and / or are held displaceably in bores of the collector strips, and the two collector strips are connected to one another by means of tie rods. Link radiators made of aluminum of this type are advantageous because, on the one hand, the collector strips and, on the other hand, the radiator links consist of extruded profile pieces, which is why they are relatively cheap to produce.

So ist aus der AT-B-370 512 ein aus Aluminium gefertigter Gliederradiator bekannt, welcher aus einzelnen miteinander verbundenen Bauteilen besteht, wobei die Befestigung der beiden Sammlerleisten und der zwischen diesen befindlichen Radiatorglieder miteinander durch die Sammlerleisten verbindende Zugstangen erfolgt. Die Bestandteile solcher Gliederradiatoren können an den Montageort geliefert und dort zusammengebaut werden. Weiters können derartige Gliederradiatoren zerlegt und in der Folge in anderen Dimensionen wieder zusammengebaut werden.From AT-B-370 512 a link radiator made of aluminum is known, which consists of individual components connected to one another, the fastening of the two header strips and the radiator links located between them being carried out by means of tie rods connecting the header strips. The components of such sectional radiators can be delivered to the assembly site and assembled there. In addition, such link radiators can be disassembled and subsequently reassembled in other dimensions.

Auch aus der US-A-1 886 645 ist ein Gliederradiator bekannt bei welchem die beiden Sammlerleisten mittels mit diesen verschraubten, vom Heizungsmedium durchströmten Rohren verbunden sind.A sectional radiator is also known from US Pat. No. 1,886,645, in which the two header strips are attached to them screwed pipes, through which the heating medium flows.

Aus Aluminium gefertigte Gliederradiatoren sind weiters auch insoferne vorteilhaft, als die Wärmeübergangswiderstände sehr gering sind, weswegen durch derartige Radiatoren hohe Wärmeleistungen übertragen werden können. Durch die geringer. Wärmeübergangswiderstände wird allerdings der gravierende Nachteil bedingt, daß bei Abschaltung der Radiatoren bzw. bei Ausfall der das Heizungswasser fördernden Pumpe eine sehr rasche Abkühlung eintritt, wodurch die Gefahr des Einfrierens des in diesen befindlichen Wassers bedingt wird. Hierdurch werden insbesondere die Verbindungen aufgebrochen, wodurch die Radiatoren so stark beschädigt werden, daß sie für eine weitere Verwendung nicht mehr geeignet sind.Link radiators made of aluminum are also advantageous insofar as the heat transfer resistances are very low, which is why high heat outputs can be transmitted by such radiators. By the lesser. Heat transfer resistance, however, has the serious disadvantage that when the radiators are switched off or if the pump delivering the heating water fails, cooling takes place very quickly, which causes the risk of freezing of the water present in it. As a result, the connections in particular are broken, causing the radiators to be damaged to such an extent that they are no longer suitable for further use.

Der Erfindung liegt demnach die Aufgabe zugrunde, einen Gliederradiator der eingangs beschriebenen Art so zu verbessern, daß dessen Verbindungen auch durch ein Einfrieren des Heizungsmediums nicht beschädigt werden.The invention is therefore based on the object of improving a sectional radiator of the type described at the outset so that its connections are not damaged even by freezing the heating medium.

Diese Aufgabe wird erfindungsgemäß dadurch gelöst, daß die Zugstangen unter der Wirkung von Federn stehen, welche die Bewegung der Sammlerleisten zueinander und gegeneinander ermöglichen.This object is achieved in that the tie rods are under the action of springs, which allow the movement of the header bars to each other and against each other.

Soferne das in einem derartigen Gliederradiator befindliche Wasser einfriert, können sich die Rohrstücke gegenüber den Sammlerleisten und bzw. oder gegenüber den Radiatorgliedern entgegen der Wirkung der Federn auseinander bewegen.If the water in such a sectional radiator freezes, the pipe sections can move apart relative to the collector strips and / or relative to the radiator links against the action of the springs.

Hierdurch wird verhindert, daß bei Einfrieren des im Radiator befindlichen Wassers eine Beschädigung desselben bedingt wird. Für den gleichen Zweck ist es vorteilhaft, wenn die Kanäle der Sammlerleisten an mindestens einer ihrer Stirnseiten mit einer verschiebbar gehaltenen Verschlußkappe ausgebildet sind.This prevents damage to the water in the radiator when it freezes. For the same purpose, it is advantageous if the channels of the collector strips are formed on at least one of their end faces with a closure cap which is held displaceably.

Vorzugsweise sind die Rohrstücke mit den Sammlerleisten einstückig ausgebildet bzw. sind sie in in den Sammlerleisten vorgesehenen Bohrungen eingeschraubt bzw. in diesen verklebt. Um dabei die erforderliche Abdichtung der Rohrstücke gegenüber den Heizungswasser führenden Bohrungen der Radiatorglieder zu bewirken, sind sie vorzugsweise weiters mittels mindestens eines Dichtungsringes gehalten und abgedichtet. Für die Befestigung der Zugstangen können von den Sammlerleisten Winkelstücke abragen, in welchen die Zugstangen gehalten sind, wobei sie unter Wirkung mindestens einer Druckfeder oder einer Zugfeder stehen.The pipe pieces are preferably formed in one piece with the header strips, or they are screwed into holes provided in the header strips or glued into them. In order to achieve the required sealing of the pipe sections with respect to the bores of the radiator members that conduct heating water, they are preferably further held and sealed by means of at least one sealing ring. For the fastening of the tie rods, angle pieces can protrude from the header strips in which the tie rods are held, whereby they are under the action of at least one compression spring or a tension spring.

Vorzugsweise weisen weiters die Kanäle der Sammlerleisten einen von der Kreisform abweichenden Querschnitt, insbesondere einen eiförmigen Querschnitt, auf. Hierdurch wird eine Verdrehungssicherung der in diese eingesetzten Verschlußklappen erzielt. Die Befestigung der Verschlußklappen kann mittels einer im Kanal der Sammlerleiste angeordneten Zugfeder erfolgen.Furthermore, the channels of the collector strips preferably have a cross-section deviating from the circular shape, in particular an egg-shaped cross-section. This ensures that the flaps inserted into them are secured against rotation. The flaps can be fastened by means of a tension spring arranged in the channel of the header.

Der Gegenstand der Erfindung ist nachstehend anhand von in der Zeichnung dargestellten Ausführungsbeispielen näher erläutert. Es zeigen:

  • Fig. 1 einen Gliederradiator in axonometrischer Darstellung,
  • Fig. 2 ein Detail aus Fig. 1, in gegenüber dieser vergrößertem Maßstab, gleichfalls in axonometrischer Darstellung und
  • Fig. 3 ein Detail gemäß der Ebene III-III der Fig. 1 in gegenüber dieser vergrößertem Maßstab.
The object of the invention is explained in more detail below with reference to exemplary embodiments shown in the drawing. Show it:
  • 1 shows a limb radiator in an axonometric view,
  • Fig. 2 shows a detail from Fig. 1, in relation to this on an enlarged scale, also in an axonometric view and
  • Fig. 3 shows a detail according to the plane III-III of Fig. 1 in relation to this on an enlarged scale.

Wie aus den Fig. 1 und 2 ersichtlich ist, weist der Gliederradiator eine obere Sammlerleiste 1 und eine untere Sammlerleiste 2 auf, welcher miteinander durch nebeneinander liegende Radiatorglieder 3 verbunden sind. Der Kanal 12 der oberen Sammlerleiste 1 ist an den Heizungsvorlauf angeschlossen und der Kanal 22 der unteren Sammlerleiste 2 ist an den Heizungsrücklauf angeschlossen. In Bohrungen 11 der oberen Sammlerleiste 1 und in Bohrungen 21 der unteren Sammlerleiste 2 sind Rohrstücke 5 eingesetzt, welche in die Bohrungen 32 der Radiatorglieder 3 einragen. Durch die Rohrstücke 5 werden einerseits die einzelnen Bestandteile des Gliederradiators miteinander verbunden und andererseits wird durch diese die Wasserführung von der oberen Sammlerleiste 1 zu der unteren Sammlerleiste 2 durch die Radiatorglieder 3 hindurch ermöglicht. Die Rohrstücke 5 sind in die Bohrungen 11 und 21 mittels Gewinde eingeschraubt, wogegen sie gegenüber den Bohrungen 32 der Radiatorglieder 3 mittels zweier Dichtringe 52 festgehalten und abgedichtet sind.As can be seen from FIGS. 1 and 2, the link radiator has an upper header 1 and a lower header 2, which are connected to one another by radiator links 3 located next to one another. The channel 12 of the upper header 1 is connected to the heating flow and the channel 22 of the lower header 2 is connected to the heating return. In bores 11 of the upper header 1 and in bores 21 of the lower header 2, pipe pieces 5 are inserted, which protrude into the bores 32 of the radiator members 3. The individual components of the link radiator are connected to one another by the pipe sections 5 and, on the other hand, this enables water to flow from the upper header 1 to the lower header 2 through the radiator links 3. The pipe sections 5 are screwed into the bores 11 and 21 by means of a thread, whereas they are held and sealed with respect to the bores 32 of the radiator members 3 by means of two sealing rings 52.

Weiters sind auf einer Seite der beiden Sammlerleisten 1 und 2 Winkelstücke 16 und 26 angeordnet, von welchen Zugstangen 6, welche unter Wirkung einer Druckfeder 7 stehen,gehalten ist. Durch die unter Wirkung der Druckfeder 7 stehende Zugstangen 6 werden die beiden Sammlerleisten 1 und 2 in ihrer gegenseitigen Lage gehalten.Furthermore, on one side of the two header strips 1 and 2 angle pieces 16 and 26 are arranged, by means of which tie rods 6, which are under the action of a compression spring 7, are held. By the pull rods 6 under the action of the compression spring 7, the two header strips 1 and 2 are held in their mutual position.

Aufgrund der Tatsache, daß die Rohrstücke 5 gegenüber den Radiatorgliedern 3 verschiebbar sind, können sich im Falle, daß das im Radiator befindliche Wasser einfriert, wodurch eine Volumensvergrößerung bedingt wird, die beiden Sammlerleisten 1 und 2 entgegen der Wirkung der Druckfedern 7 auseinander bewegen, wodurch eine Beschädigung des Gliederradiators verhindert wird. Aufgrund dieser Ausbildung können auch einzelne Bestandteile der Gliederradiatoren, nämlich die Sammlerleisten 1 und 2, die Radiatorglieder 3, die Rohrstücke 5 und die Zugstangen 6, an die Baustelle geliefert werden und dort zu Radiatoren in der erforderlichen Größe zusammengebaut werden. In analoger Weise können an Baustellen befindliche Radiatoren in einfacher Weise zerlegt werden und können sie verkleinert oder vergrößert werden bzw. können schadhafte Teile ausgewechselt werden.Due to the fact that the pipe pieces 5 are displaceable relative to the radiator members 3, in the event that the water in the radiator freezes, which causes an increase in volume, the two header strips 1 and 2 can move apart against the action of the compression springs 7, whereby damage to the sectional radiator is prevented. Due to this design, individual components of the link radiators, namely the header strips 1 and 2, the radiator links 3, the pipe sections 5 and the tie rods 6, can be delivered to the construction site and assembled there into radiators of the required size. In an analogous manner, radiators located on construction sites can be dismantled in a simple manner and they can be reduced or enlarged or defective parts can be replaced.

Wie weiters aus Fig. 3 der Zeichnung ersichtlich ist, ist der Kanal 12 der oberen Sammlerleiste 1 ebenso wie der Kanal der unteren Sammlerleiste durch eine Verschlußkappe 13, die durch eine Zugfeder 14 in ihrer Lage gehalten ist, verschlossen. Die erforderliche Abdichtung wird gleichfalls mittels zweier O-Ringe 15 bewirkt. Da auch aufgrund dieser Ausbildung die Verschlußkappe 13 gegenüber der Sammlerleiste 1 verschiebbar ist, kann auch eine Ausdehnung des in den Kanälen der Sammlerleisten befindlichen Wassers infolge einer Vereisung auftreten, ohne daß hierdurch eine Sprengung der Sammlerleisten bedingt wird.3 of the drawing, the channel 12 of the upper header 1 as well as the channel of the lower header is closed by a cap 13 which is held in position by a tension spring 14. The required sealing is also done by means of two O-rings 15 causes. Since the closure cap 13 can also be moved relative to the header 1 due to this design, an expansion of the water in the channels of the header can occur as a result of icing, without this causing an explosion of the header.

Insbesondere um Dehnungsgeräusche zu verhindern, sind weiters zwischem einem Flansch 53 der Rohrstücke 5 und den anliegenden Stirnflächen der anliegenden Bauelemente Dichtungsscheiben 54 eingesetzt.In particular in order to prevent expansion noises, sealing disks 54 are also inserted between a flange 53 of the tube pieces 5 and the abutting end faces of the adjacent components.

Soferne der Radiator eingefroren ist, wobei die Sammlerleisten 1 und 2 entgegen der Wirkung der Zugfedern 7 auseinander bewegt werden, kann durch diese Zugfedern 7 nach Auftauen des Heizungswassers wieder die richtige Lage der einzelnen Bauelemente hergestellt werden.If the radiator is frozen, the collector strips 1 and 2 being moved apart against the action of the tension springs 7, the correct position of the individual components can be restored by these tension springs 7 after thawing the heating water.
