Abstract

The radiator has multiple optical radiator elements arranged next to one another and two rows of vertical heating tubes (3) arranged in a consecutive manner. The vertical heating tubes are connected with horizontal collective tube segments (1, 1', 2) in a fluid conducting manner at its oppositely lying pipe ends. The tube segments have pipe optics and stay in connection with each other by partial fluid conducting sections. The pipe optics is formed by a cross section varying over the length of the tube segments. An independent claim is also included for a method for manufacturing a tube radiator.

Description

Die Erfindung betrifft einen Röhrenheizkörper und ein Verfahren zu dessen Herstellung. Herkömmliche Röhrenheizkörper werden beispielsweise in den Druckschriften CH - PS 449 891 , EP 0 644393 B1 , DE 198 00 230 C2 und DE 93 14 040 U1 offenbart. In der DE - OS 15 79 967 wird ein Heizkörperelement und ein aus derartigen Elementen hergestellter Heizkörper beschrieben.The invention relates to a tubular heater and a method for its production. Conventional tubular heaters, for example, in the publications CH - PS 449 891 . EP 0 644393 B1 . DE 198 00 230 C2 and DE 93 14 040 U1 disclosed. In the DE - OS 15 79 967 a radiator element and a heater made from such elements will be described.

Röhrenheizkörper bestehen häufig aus mehreren aneinander angeordneten und miteinander an den Naben verbundenen gleichartigen Radiatorgliedern. Die Radiatorglieder bestehen dabei meist aus zusammengeschweißten Blechschalen, wobei zur Herstellung größerer Bauformen zwischen Rohranschlussstutzen von aus Blechschalen gebildeten Endstücken Rohre eingeschweißt werden. Durch die Länge der Rohre kann die Bauhöhe der Radiatorelemente variabel gestaltet werden und den jeweiligen Anforderungen angepasst werden.Tubular heaters often consist of several adjacently arranged and connected to the hubs similar radiator members. The radiator members usually consist of welded together sheet metal shells, being welded to produce larger designs between pipe connection piece formed from sheet metal shells end pieces of pipes. Due to the length of the tubes, the overall height of the radiator elements can be made variable and adapted to the respective requirements.

Bei derartigen Heizkörpern erfolgt das Durchströmen der mehreren Lagen von Radiatorgliedern üblicherweise in derselben Richtung, beispielsweise bei vertikalen angeordneten Heizröhren entweder in einer Strömungsrichtung von unten nach oben oder oben nach unten, je nach Anordnung von Vor- und Rücklaufanschluss. Es hat sich aber gezeigt, dass ein Heizkörper eine größere Behaglichkeit erzeugt und die Wärmeverluste an die Außenwand, an welcher Heizkörper meist montiert sind, geringer sind, wenn die in den Raum gerichtete Seite des Heizkörpers bevorzugt durchströmt wird.In such radiators, the flow through the plurality of layers of radiator members is usually in the same direction, for example, in vertical heating tubes either in a flow direction from bottom to top or top to bottom, depending on the arrangement of flow and return port. However, it has been found that a radiator generates greater comfort and the heat losses to the outer wall, on which radiators are usually mounted, are lower when the directed into the room side of the radiator is preferably flowed through.

Aus der DE10 2006 031 406 A1 ist bereits ein Röhrenradiator bekannt, welcher an seiner Vorderseite eine höhere Strahlungsleistung abgibt als an seine inneren oder hinteren Rohrlagen. Die dafür erforderliche Vorrichtung begrenzt jedoch die Anschlussarten des Heizkörpers und bedeutet einen zusätzlichen konstruktiven Aufwand bezüglich des Einbaus. Je nach Heizkörperlänge müssen Einbauten in den entsprechenden Abmaßen vorgehalten werden. Ein Röhrenheizkörper anderer Bauart ist aus der DE 20 2007 005 330 U1 bekannt. Der Röhrenheizkörper weist Sammelrohre auf, die eine Vorrichtung umfassen, die eine gezielte Durchströmung der dem Raum zugewandten Röhrenwand ermöglicht. Der Röhrenheizkörper weicht jedoch in seiner Optik von der traditionellen Form des Röhrenradiators ab und wird deshalb von Abnehmern nur schwer angenommen.From the DE10 2006 031 406 A1 a tubular radiator is already known, which emits a higher radiation power at its front than at its inner or rear pipe layers. The device required for this, however, limits the connection types of the radiator and means an additional design effort with respect to the installation. Depending on the radiator length, fittings must be kept in the appropriate dimensions. A tubular heater of another type is from the DE 20 2007 005 330 U1 known. The tubular radiator has Collecting tubes, which include a device that allows a targeted flow through the room facing the tube wall. The tubular radiator, however, differs in appearance from the traditional shape of the tube radiator and is therefore difficult to accept by customers.

Bei der derzeitigen Konstruktion des Röhrenradiators (Kopfstücke von denen das Wasser parallel, gleichzeitig in alle Rohrreihen geleitet wird) ist dies (zumindest mit einem technisch vertretbarem Aufwand bzw. bezahlbaren Kosten) nicht durchführbar.In the current construction of the tube radiator (head pieces from which the water is conducted in parallel, at the same time in all rows of tubes), this is not feasible (at least with a technically justifiable expense or cost).

Die Aufgabe der Erfindung besteht deshalb darin einen Röhrenadiator neuen Typs mit mindestens zwei Lagen von Heizröhren zu schaffen, welcher an seiner Vorderseite eine höhere Strahlungsleistung abgibt als an seine hinteren und/oder inneren Lagen von Heizröhren, wobei die traditionelle Optik eines herkömmlichen Röhrenradiators beibehalten werden soll. Eine weitere Aufgabe der Erfindung besteht darin ein Verfahren zur Herstellung eines derartigen Röhrenheizkörpers vorzuschlagen, mit welchem die oben genannte Aufgabe technisch zu wirtschaftlichen Herstellkosten umsetzbar ist.The object of the invention is to provide a tube radiator of new type with at least two layers of heating tubes, which emits at its front side a higher radiant power than at its rear and / or inner layers of heating tubes, while maintaining the traditional look of a conventional Röhrenradiators , Another object of the invention is to provide a method for producing such a tubular heater, with which the above object is technically feasible at economic production costs.

Erfindungsgemäß wird dazu vorgeschlagen, dass die Sammelrohrsegmente des Röhrenheizkörpers mit Hilfe des als "Hydroforming" oder als "Innenhochdruckumformung (IHU)" bekannten Verfahrens hergestellt werden. Das IHU - Verfahren ist hinlänglich bekannt und in der einschlägigen Literatur beschrieben. Beispielsweise werden dazu die Druckschriften DE 40 17 072 C2 , US 3,625,040 und DE 197 15 593 genannt. Es wird vorzugsweise zum Herstellen unterschiedlich geformter Hohlkörper aus einem Halbzeug, beispielsweise ein rohrförmiges Werkstück angewendet. Ein Rohrabschnitt z.B. aus Stahl oder Kupfer wird dabei in ein mehrteiliges Innenhochdruck-Umformwerkzeug ohne feste Innenmatrize mit von Axialzylindern betätigten Dichtstempeln bzw. Umformstößeln eingelegt. Nach dem verschließen der Enden des Rohrabschnitts durch die Dichtstempel wird der Rohrabschnitt mit Hilfe eines geeigneten Druckmittels mit hohem Innendruck beaufschlagt und unter gleichzeitiger Beaufschlagung mit axialem Druck (durch die Dichtstempel) auf die Rohrwandung umgeformt. Der Axialdruck und der Innendruck bewirken, dass sich der Rohrabschnitt an die endgültige Form des Hohlkörpers aufweisende Innenkontur bzw. -wandung des Konturraums des Umformwerkzeugs anlegt. Beim IHU-Verfahren wird der Werkstoff in den plastischen Zustand versetzt, der während des gesamten Vorgangs unter Berücksichtigung von Werkstoffverfestigung und etwaigen Werkzeugkräften aufrechterhalten wird. Aus der DE 199 54 456 A1 ist es bekannt wasserführende Armaturen aus der Sanitär- und Heizungsinstallation, nämlich dünnwandige Lötfittinge in Form von T-Stücken nach diesem Verfahren herzustellen.According to the invention, it is proposed that the header segments of the tubular heater be produced by means of the method known as "hydroforming" or "hydroforming (IHU)". The hydroforming process is well known and described in the pertinent literature. For example, to the pamphlets DE 40 17 072 C2 . US 3,625,040 and DE 197 15 593 called. It is preferably used for producing differently shaped hollow bodies made of a semifinished product, for example a tubular workpiece. A pipe section, for example made of steel or copper, is inserted into a multi-part hydroforming die without a fixed inner die with sealing dies or forming tappets actuated by axial cylinders. After closing the ends of the pipe section by the sealing ram, the pipe section is acted upon by means of a suitable pressure medium with high internal pressure and with simultaneous application of axial pressure (by the sealing ram) formed on the pipe wall. The axial pressure and the internal pressure cause the pipe section to conform to the final shape of the Hollow body having inner contour or wall of the contour space of the forming tool applies. In the hydroforming process, the material is placed in the plastic state, which is maintained during the entire process, taking into account material hardening and possible tool forces. From the DE 199 54 456 A1 It is known to produce water-bearing fittings from the sanitary and heating installation, namely thin-walled soldering in the form of tees by this method.

Aus der Druckschrift ist aber nicht bekannt, die Rohrsegmente eines Heizkörpers nach diesem Verfahren herzustellen.From the document is not known to produce the pipe segments of a radiator by this method.

Die vorliegende Erfindung umfasst demgemäß einen Röhrenradiator der optisch aus mehreren nebeneinander angeordneten üblichen Radiatorelementen besteht und mindestens zwei hintereinander angeordnete Rohrreihen aus vertikalen Heizrohren ausweist, wobei die vertikalen Heizrohre an ihren gegenüberliegenden Rohrenden jeweils mit horizontalen Sammelrohrsegmenten fluidleitend verbunden sind und die Sammelrohrsegmente eine Gliederrohroptik aufweisen und mit zumindest teilweise fluidleitend Verbindungsteilen miteinander verbunden sind. Vorteilhaft wird dabei die Gliederrohroptik der Sammelrohrsegmente durch einen über die Länge der Sammlerohrsegmente variierenden Querschnitt gebildet. Die Sammelrohrsegmente sind mit Rohranschlussstutzen versehen, die mit den vertikalen Heizrohren verbindbar sind. Nach einer Ausführung der Erfindung ist vorgesehen, dass die Sammelrohrsegmente Rohranschlussstutzen aufweisen, die mit dem jeweils dahinter liegenden Sammelrohrsegment zumindest teilweise fluidleitend verbunden sind. Vorteilhaft sind die seitlichen Rohrenden der Sammelrohrsegmente durch Abdeckungen verschlossen und/oder es sind Deckel mit Gewindemuffen zum Anschluss an einen Heizkreis vorgesehen. Nach einer besonders vorteilhaften Ausführung der Erfindung werden die Heizrohre der dem Raum zugewandeten vorderen Seite des Heizkörpers durch Anschlusskonfiguration von Vor- und Rücklauf des Heizfluids und entsprechenden fluidleitenden Einbauten und/oder Stauscheiben bevorzugt vom Heizfluid durchströmt. Dadurch wird eine größere Behaglichkeit erzeugt und die Wärmeverluste an die Außenwand, an welcher Heizkörper meist montiert sind werden verringert. Zum Umfang der Erfindung gehört auch ein Verfahren zur Herstellung von Röhrenradiatoren, die optisch aus mehreren nebeneinander angeordneten Radiatorelementen bestehen und aus mindestens zwei hintereinander angeordneten Rohrreihen aus vertikalen Heizrohren hergestellt werden. Erfindungsgemäß werden dabei die vertikalen Heizrohre an ihren gegenüberliegenden Enden durch Hochtemperaturlöten mit Rohranschlussstutzen von horizontalen Sammelrohrsegmenten fluidleitend verbunden. Die Sammelrohrsegmente werden durch Innen-Hochdruck-Umformen hergestellt und weisen dabei vorteilhaft eine übliche Gliederrohroptik auf. Die Sammelrohrsegmente werden beim Zusammenbau des Heizkörpers miteinander zumindest teilweise fluidleitend, z.B. durch Schweißen oder Löten, zusammengefügt. Vorteilhaft wird die Gliederrohroptik der Sammelrohrsegmente durch einen über die Länge der Sammlerohrsegmente variierenden Querschnitt durch Innen-Hochdruck-Umformen hergestellt. Die Sammelrohrsegmente werden mit Rohranschlussstutzen zur Verbindung mit den vertikalen Heizrohren versehen. Nach einer besonderen Ausführung der Erfindung werden auch die Sammelrohrsegmente mit Rohranschlussstutzen zur zumindest teilweise fluidleitenden Verbindung mit dem dahinter liegenden Sammelrohrsegmenten versehen.The present invention accordingly comprises a tube radiator optically consisting of a plurality of juxtaposed conventional radiator elements and identifies at least two successively arranged rows of tubes from vertical heating tubes, wherein the vertical heating tubes are fluidly connected at their opposite tube ends respectively with horizontal manifold segments and the manifold segments have a Schiederrohroptik and with at least partially fluid-conducting connecting parts are interconnected. Advantageously, the limb-pipe structure of the manifold segments is formed by a cross section that varies over the length of the collector pipe segments. The manifold segments are provided with pipe connection pieces, which are connectable to the vertical heating pipes. According to one embodiment of the invention, it is provided that the collecting pipe segments have pipe connecting pieces which are at least partially connected fluid-conductively to the respective collecting pipe segment lying behind them. Advantageously, the lateral pipe ends of the manifold segments are closed by covers and / or there are provided with threaded sleeves for connection to a heating circuit cover. According to a particularly advantageous embodiment of the invention, the heating tubes of the room facing the front side of the radiator are preferably flowed through by connecting configuration of flow and return of the heating fluid and corresponding fluid-conducting internals and / or baffle plates from the heating fluid. As a result, a greater comfort is generated and the heat losses to the outer wall to which radiators are usually mounted are reduced. The scope of the invention also includes a method for producing tube radiators which optically consist of a plurality of radiator elements arranged next to one another and of at least one two successively arranged rows of tubes are made of vertical heating pipes. According to the invention, the vertical heating pipes are fluid-conductively connected at their opposite ends by high-temperature soldering with pipe connecting pieces of horizontal header segments. The collection tube segments are produced by internal high-pressure forming and thereby advantageously have a conventional Schiederrohroptik. The manifold segments are at least partially fluid-conducting, for example, by welding or soldering together when assembling the radiator. Advantageously, the limb-pipe structure of the manifold segments is produced by an over the length of Sammlerohrsegmente varying cross-section by internal high-pressure forming. The manifold segments are provided with pipe connections for connection to the vertical heating pipes. According to a particular embodiment of the invention, the collection tube segments are provided with pipe connection piece for at least partially fluid-conducting connection with the underlying manifold segments.

Der erfindungsgemäße Heizkörper ist aus mindestens zwei Segmenten (Rohrregistern) aufgebaut, die hintereinander angeordnet sind und über entsprechende, teilweise Heizfluid führende Verbindungsteile 1 n, 2.n, verbunden sind, wodurch eine serielle Zwangsdurchströmung der einzelnen Segmenten ermöglicht wird. Die genannten Verbindungsteile 1.n, 2.n sind bevorzugt an den Enden der seitlichen sich gegenüberliegenden Innenseiten der Sammelrohre 1 bzw. 2 vorgesehen. Dabei kann es sich um in den seitlichen Öffnungen angeordnete Durchflussröhrchen, Stauscheiben, Stauscheiben mit Entlüftungsbohrungen etc. handeln, die entweder den Durchfluss des Heizmediums erlauben oder verhindern. Jedes Rohrregister besteht aus 2 Sammelrohren und den dazwischen angeordneten Heizrohren. Erfindungsgemäß weisen die Sammelrohre nicht wie herkömmliche Rohre einen gleich bleibenden Querschnitt über die gesamt Länge auf. Der Querschnitt der Rohre variiert über die Länge zur Darstellung der Gliederoptik des Heizkörpers. Derartige Rohre lassen sich nicht mit einem herkömmlichen Verfahren (schweißen, ziehen) herstellen. Erfindungsgemäß werden diese Rohre deshalb nach dem Innen-Hochdruck-Umform- Verfahren (IHU) hergestellt. Um mehrreihige Typen darstellen zu können, sind mindestens zwei Sammelrohrausführungen (Sammelrohr 1, 1' (vorne/hinten) - mittiges Sammelrohr 2) vorgesehen, die in den Fig. 1 und 2 dargestellt sind. Ein mittiges Sammelrohr 2 ist nur bei mehr als zweireihigen Heizkörpern erforderlich. Mit den Bezugszeichen 1 a bzw. 2a sind die Rohranschlussstutzen bezeichnet. Die Fig. 3 und 4 zeigen jeweils die zusammengefügten oberen bzw. unteren Sammelrohre eines 4 - reihigen Heizkörpers in perspektivischer Ansicht. Die Sammelrohre können durch Schweißen oder Löten miteinander verbunden werden. Dabei können die einzelnen Sammelrohre seitlich eng miteinander zusammengefüht werden, wie z.B. in der Fig. 8 gezeigt. Die Sammelrohre können aber auch voneinander durch seitliche Rohranschlussstutzen (1 b, 2b) oder stärker ausgebildete Verbindungsabschnitte 1.n, 2.nbeabstandet sein, wie es in Fig. 9 gezeigt wird. Die Figuren 5 bis 9 zeigen mehrere mögliche Ausführungsformen und Typen kompletter Röhrenheizkörper. Als Fügeverfahren für die Sammelrohre 1 bzw. 2 mit den Heizrohren 3, ist das kostengünstige Hochtemperaturlöten (im Durchlaufofen) vorgesehen. Eine nachträgliche Bearbeitung der Fügestellen (durch Schleifen), die bei den herkömmlichen Abrennschweißverfahren erforderlich ist, ist nicht mehr notwendig. Die Heizrohre 3 können dabei jede denkbare Querschnittsform aufweisen. Die Gliederrohroptik der Sammelrohre und die Rohranschlussstutzen können dabei je nach Heizrohrform (rund, eckig, elipsenförmig etc.) ausgebildet sein.The radiator according to the invention is composed of at least two segments (tube registers), which are arranged one behind the other and over corresponding, partially heating fluid-carrying connecting parts 1 n, 2.n, are connected, whereby a serial forced flow of the individual segments is made possible. The aforementioned connecting parts 1.n, 2.n are preferably provided at the ends of the lateral opposite inner sides of the headers 1 and 2 respectively. These can be arranged in the side openings flow tubes, baffle plates, baffle plates with vent holes, etc., which allow either the flow of the heating medium or prevent. Each pipe register consists of 2 headers and the heating pipes in between. According to the invention, the headers do not have a constant cross-section over the entire length, as do conventional tubes. The cross-section of the tubes varies over the length to represent the limb appearance of the radiator. Such pipes can not be produced by a conventional method (welding, drawing). According to the invention, these pipes are therefore produced by the internal high-pressure forming process (IHU). In order to represent multi-row types, at least two collection tube designs (header 1, 1 '(front / rear) - central header 2) are provided, which in the Fig. 1 and 2 are shown. A central manifold 2 is required only for more than two-row radiators. By the reference numeral 1 a and 2a, the pipe connection piece are designated. The Fig. 3 and 4 each show the assembled upper and lower manifolds of a 4 - row radiator in a perspective view. The headers can be connected by welding or soldering. The individual headers can be made close together laterally, such as in the Fig. 8 shown. But the manifolds can also be spaced apart from each other by lateral pipe connection pieces (1 b, 2 b) or more strongly formed connecting portions 1. n, 2.nb, as it is in Fig. 9 will be shown. The FIGS. 5 to 9 show several possible embodiments and types of complete tubular radiators. As a joining method for the headers 1 and 2 with the heating pipes 3, the cost-effective high-temperature brazing (in a continuous furnace) is provided. Subsequent machining of the joints (by grinding), which is required in the conventional Abrennschweißverfahren is no longer necessary. The heating pipes 3 can have any conceivable cross-sectional shape. The Schiederrohroptik the headers and the pipe connection pieces can be formed depending on the shape of the heating tube (round, square, elliptical, etc.).

Die serielle Durchströmung von Heizkörpern die aus mindestens zwei Abschnitten aufgebaut sind, bringt mehrere Vorteile gegenüber herkömmlich (parallel) durchströmten Heizkörpern mit sich. Dabei wird zuerst die vorderste (zum Raum gewandte) Rohrreihe durchströmt und anschließend erst die hintere(n) Rohrreihe(n), wodurch das Wohlfühlempfinden entscheidend verbessert wird. Ausgehend vom Vorlauf V wird das Heizmedium durch eine gezielte Führung mit Hilfe von Stauscheiben 4, bzw. Durchflussröhrchen 1.n, 2.n in die vordere Reihe des Röhrenheizkörpers und anschließend in die dahinter liegenden Reihen des Heizkörpers geleitet. Die Stauscheiben 4 können dabei im Bedarfsfall mit Entlüftungsbohrungen versehen sein.The serial flow of radiators which are made up of at least two sections, brings several advantages over conventional (parallel) radiators flowed through with it. The first row of pipes (facing the room) is first flowed through, followed by the back row (s) of pipe, which decisively improves the sense of well-being. Starting from the flow V, the heating medium is passed through a targeted guide with the aid of baffle plates 4, or flow tube 1.n, 2.n in the front row of the tubular heater and then in the underlying rows of the radiator. The baffle plates 4 can be provided with vent holes if necessary.
