Abstract

The invention relates to a radiator having two perpendicular tubes (1, 2) which extend at a distance parallel to one another and at the lower end can each be joined to a permanently installed feed or return and are connected to one another by a plurality of horizontal tubes (3), which likewise extend parallel to one another and whose interior is connected via openings constructed in the mutually welded tubes (1, 2, 3) to the interior of the perpendicular tubes (1, 2). In order to be able independently of the separation of the perpendicularly extending tubes (1) to match the heat exchanging surface of the radiator to the particular requirement, the horizontal tubes (3) are constructed in the form of a C and, by means in each case of their end pieces (3a) adjoining a tube bend (3b), they are respectively joined to one of the perpendicular tubes (1 or 2) in such a way that the tube middle piece (3c) extending between the two tube bends (3b) and exceeding the spacing between the perpendicular tubes (1, 2) extends at a distance in front of the perpendicular tubes (1, 2). <IMAGE>

Description

Die Erfindung betrifft einen Heizkörper mit zwei senkrechten, im Abstand parallel zueinander verlaufenden Rohren, die am unteren Ende jeweils an einen ortsfest verlegten Vorlauf bzw. Rücklauf anschließbar und miteinander durch eine Mehrzahl von waagerechten, ebenfalls parallel zueinander verlaufenden Rohren mit kreisförmigem Querschnitt verbunden sind, deren Inneres über in den miteinander verschweißten Rohren ausgebildete Öffnungen mit dem Inneren der senkrechten Rohre in Verbindung steht, wobei die waagerechten Rohre C-förmig ausgebildet und mit ihren sich an jeweils einen Rohrbogen anschließenden Endstücken derart an jeweils eines der senkrechten Rohre angeschlossen sind, daß das zwischen den beiden Rohrbögen verlaufende, den Abstand zwischen den senkrechten Rohren übersteigende Rohrmittelstück mit Abstand vor den senkrechten Rohren verläuft.The invention relates to a radiator with two vertical, mutually parallel pipes, which can be connected at the lower end to a fixed flow or return and connected to each other by a plurality of horizontal, also parallel pipes with a circular cross-section, the The interior is connected to the interior of the vertical tubes via openings formed in the welded tubes, the horizontal tubes being C-shaped and with their end pieces adjoining a tube bend each connected to one of the vertical tubes such that the between pipe center piece running the two pipe bends, which exceeds the distance between the vertical pipes, runs at a distance in front of the vertical pipes.

Ein Heizkörper der voranstehend beschriebenen Art ist aus der DE-U-89 06 829 bekannt. Bei dieser bekannten Konstruktion sind die senkrecht verlaufenden Rohre mit rechtseckigem Querschnitt ausgeführt und in einem zentralen Verteilungskörper zusammengefaßt, und zwar entweder unmittelbar aneinanderliegend oder mit Abstand parallel zueinander verlaufend. Die waagerechten, in der Draufsicht C-förmigen und mit kreisförmigem Querschnitt ausgebildeten Rohre werden in Öffnungen eingeschweißt, die in den Seitenwänden der rechteckigen, senkrecht verlaufenden Rohre ausgebildet werden.A heater of the type described above is known from DE-U-89 06 829. In this known construction, the vertical tubes are designed with a rectangular cross-section and combined in a central distribution body, either directly adjacent to one another or parallel to one another at a distance. The horizontal, C-shaped in plan view and designed with a circular cross-section Pipes are welded into openings that are formed in the side walls of the rectangular, perpendicular pipes.

Bei diesem bekannten Heizkörper kann die Wärmeaustauschfläche nicht nur durch Variation der Anzahl der waagerechten Rohre und gegebenenfalls die Länge der senkrechten Rohre an den jeweiligen Bedarf angepaßt werden, sondern auch durch eine Veränderung der Länge der C-förmig ausgebildeten, waagerecht verlaufenden Rohre. Die bekannte Konstruktion vernachlässigt jedoch Fragen der Standardisierung, der wirtschaftlichen Herstellung und Verwendung und auch der optischen Wirkung.In this known radiator, the heat exchange surface can be adapted not only by varying the number of horizontal pipes and, if appropriate, the length of the vertical pipes, but also by changing the length of the C-shaped, horizontal pipes. However, the known construction neglects questions of standardization, economical production and use and also the visual effect.

Der Erfindung liegt die Aufgabe zugrunde, einen Heizkörper der aus der DE-U-89 06 829 bekannten Art derart weiterzubilden, daß bei Aufrechterhaltung sämtlicher Möglichkeiten zur Veränderung der Wärmeaustauschfläche einerseits eine Standardisierung derartiger Heizkörper möglich und andererseits die Herstellung und Montage vereinfacht und damit wirtschaftlicher gemacht werden.The invention has for its object to develop a radiator of the type known from DE-U-89 06 829 in such a way that, while maintaining all possibilities for changing the heat exchange surface, standardization of such radiators is possible on the one hand and production and assembly simplified and thus made more economical on the other will.

Die Lösung dieser Aufgabenstellung durch die Erfindung ist dadurch gekennzeichnet, daß die Endstücke der waagerechten Rohre mit der Vorder- oder Rückseite der senkrechten, ebenfalls mit kreisförmigem Querschnitt ausgebildeten Rohre verbunden sind und daß die Verbindung der waagerechten und senkrechten Rohre mittels einer Kreuzlochpreßschweißung erfolgt.The solution to this problem by the invention is characterized in that the end pieces of the horizontal pipes are connected to the front or rear of the vertical pipes, also of circular cross-section, and that the horizontal and vertical pipes are connected by means of cross-hole welding.

Durch die Verbindung der Endstücke der waagerechten Rohre mit der Vorder- oder Rückseite der senkrechten Rohre können die C-förmig ausgebildeten und waagerecht verlaufenden Rohre mit gewissen Fertigungstoleranzen an regelmäßig im gleichen Abstand verlaufende senkrechte Rohre angeschlossen werden. Hierdurch erhält der Heizkörper nicht nur eine optisch leichte Wirkung; durch die standardisierten senkrechten Rohre wird die maschinelle Herstellung vereinfacht und damit wirtschaftlicher, und zwar unter gleichzeitiger Standardisierbarkeit der Anschlüsse für den Vor- und Rücklauf. Die erfindungsgemäße Verbindung der waagerechten und senkrechten Rohre mittels einer Kreuzlochpreßschweißung ergibt nicht nur eine weitere Herstellungsvereinfachung, sondern eine sehr sichere Verbindung, die auch hohen Drücken standhält. Insgesamt ist der erfindungsgemäße Heizkörper trotz standardisiertem Abstand der Vor- und Rücklaufrohre bei Aufrechterhaltung einer besonders ansprechenden optischen Wirkung nahezu beliebig variabel und dennoch bei der Herstellung und Montage besonders kostengünstig und wirtschaftlich.By connecting the end pieces of the horizontal pipes to the front or back of the vertical pipes, the C-shaped and horizontal pipes with certain manufacturing tolerances can be connected to vertical pipes that are regularly spaced apart. This not only gives the radiator an optically light effect; The standardized vertical pipes make the mechanical Manufacturing simplified and therefore more economical, while at the same time standardizing the connections for the flow and return. The connection of the horizontal and vertical pipes according to the invention by means of cross-hole pressure welding not only results in a further simplification of production, but also a very secure connection which can also withstand high pressures. Overall, despite the standardized spacing of the supply and return pipes while maintaining a particularly appealing optical effect, the radiator according to the invention can be varied as desired, and yet is particularly economical and economical to manufacture and assemble.

Gemäß einer Ausgestaltung der Erfindung können die Rohrbögen mindestens eines der waagerechten Rohre einen größeren Biegeradius als die Rohrbögen der restlichen Rohre aufweisen. Hierdurch liegt das zwischen den Rohrbögen verlaufende Rohrmittelstück räumlich vor den Rohrmittelstücken der anderen waagerechten Rohre, so daß es insbesondere zum Aufhängen von zu trocknenden Gegenständen verwendet werden kann. Selbstverständlich können auch mehrere waagerecht verlaufende Rohre derart ausgeführt sein.According to one embodiment of the invention, the pipe bends of at least one of the horizontal pipes can have a larger bending radius than the pipe bends of the remaining pipes. As a result, the pipe center piece running between the pipe elbows is spatially in front of the pipe center pieces of the other horizontal pipes, so that it can be used in particular for hanging objects to be dried. Of course, several horizontally extending tubes can also be designed in this way.

Um einerseits die Größe der Wärmetauscherfläche des erfindungsgemäßen Heizkörpers weiter variieren zu können und andererseits den optischen Eindruck des erfindungsgemäßen Heizkörpers an unterschiedliche Gegebenheiten anpassen zu können, wird weiterhin vorgeschlagen, die Rohrmittelstücke der Rohre unterschiedlich lang auszubilden. Hierdurch ergeben sich Heizkörper der unterschiedlichsten Form und mit unterschiedlich großer Wärmeaustauschfläche bei gleicher Länge und gleichem Abstand der senkrecht verlaufenden Rohre.In order on the one hand to be able to further vary the size of the heat exchanger surface of the radiator according to the invention and on the other hand to be able to adapt the optical impression of the radiator according to the invention to different circumstances, it is further proposed to design the pipe center pieces of the pipes of different lengths. This results in radiators of the most varied shapes and with different heat exchange surfaces with the same length and the same distance between the vertically extending pipes.

Es ist weiterhin möglich, die waagerecht verlaufenden Rohre mit unterschiedlichem Abstand zueinander an den senkrechten Rohren anzuordnen. Auch hierdurch ist eine Variation der Wärmeaustauschfläche und des Aussehens der Heizkörper in vielfältiger Form möglich.It is also possible to arrange the horizontal pipes at different distances from one another on the vertical pipes. This is also a variation the heat exchange surface and the appearance of the radiators in a variety of forms.

Gemäß einem weiteren Merkmal können die senkrechten Rohre miteinander durch eine tafelartige Verkleidung verbunden sein, die den Raum zwischen den Rohren mindestens teilweise abdeckt. Eine derartige Verkleidung, die vorzugsweise ebenfalls aus Metall hergestellt wird, vergrößert die durch Wärmeleitung vom Heizmedium aufgeheizte Wärmetauscherfläche. Gleichzeitig können mit einer derartigen Verkleidung die Anschlüsse und Ventile des Heizkörpers abgedeckt werden. Schließlich stellt diese tafelartige Verkleidung ein weiteres Element zur optischen Variation des erfindungsgemäßen Heizkörpers dar.According to a further feature, the vertical tubes can be connected to one another by a panel-like covering which at least partially covers the space between the tubes. Such a cladding, which is preferably also made of metal, increases the heat exchanger area heated by heat conduction from the heating medium. At the same time, the connections and valves of the radiator can be covered with such a covering. Finally, this panel-like cladding represents a further element for the optical variation of the radiator according to the invention.

Eine weitere Ausbildung der Erfindung schlägt vor in mindestens einem der senkrechten Rohre mindestens eine elektrische Heizvorrichtung anzuordnen. Durch eine derartige zusätzliche elektrische Heizvorrichtung ist es möglich, entweder dem Heizkörper zusätzliche Wärme zuzuführen oder ihn, vorzugsweise in der Übergangszeit, unabhängig von der zentralen Heizungsanlage elektrisch zu betreiben. Selbstverständlich ist es möglich, derartige elektrische Heizvorrichtungen herausnehmbar in dem Heizkörper anzuordnen, so daß sie auch nachträglich eingebaut oder ausgetauscht werden können.A further embodiment of the invention proposes to arrange at least one electric heating device in at least one of the vertical tubes. Such an additional electrical heating device makes it possible either to supply the radiator with additional heat or to operate it electrically, preferably in the transition period, independently of the central heating system. Of course, it is possible to arrange such electrical heating devices removably in the radiator so that they can also be installed or replaced later.

Der in den Figuren 1 und 2 dargestellte Heizkörper umfaßt zwei senkrechte, im Abstand parallel zueinander verlaufende Rohre 1 und 2. Während das untere Ende des Rohres 1 an einen ortsfest verlegten Vorlauf anschließbar ist, wird das untere Ende des Rohres 2 an einen Rücklauf angeschlossen, der ebenfalls ortsfest verlegt ist, wobei der Abstand zwischen Vorlauf und Rücklauf vom Hersteller fest vorgegeben und nicht mehr veränderlich ist und bauseitig bei der Verlegung der Rohrleitungen berücksichtigt werden kann. Die beiden senkrecht verlaufenden Rohre 1 und 2 sind miteinander durch eine Mehrzahl von waagerechten, ebenfalls parallel zueinander verlaufenden Rohren 3 verbunden. Diese waagerechten Rohre 3 sind C-förmig ausgebildet. Jedes Rohr 3 besteht aus zwei Endstücken 3a, zwei sich an die Endstücke 3a anschließenden Rohrbögen 3b und einem die Rohrbögen 3b verbindenden Rohrmittelstück 3c. Vorzugsweise sind diese Rohre 3 einstückig durch entsprechendes Biegen eines Rohrstückes hergestellt.The radiator shown in FIGS. 1 and 2 comprises two vertical pipes 1 and 2, spaced parallel to one another. While the lower end of the pipe 1 can be connected to a fixed flow, the lower end of the pipe 2 is connected to a return, which is also installed in a fixed position, whereby the distance between the flow and return is fixed by the manufacturer and can no longer be changed and can be taken into account on site when laying the pipes. The two perpendicular tubes 1 and 2 are connected to each other by a plurality of horizontal, also connected to each other parallel tubes 3. These horizontal tubes 3 are C-shaped. Each pipe 3 consists of two end pieces 3a, two pipe bends 3b adjoining the end pieces 3a and a pipe middle piece 3c connecting the pipe bends 3b. These tubes 3 are preferably produced in one piece by appropriately bending a tube piece.

Mit ihren Endstücken 3a sind die waagerecht verlaufenden Rohre 3 mit den senkrecht verlaufenden Rohren 1 und 2 verbunden, so daß das Innere der Rohre 1,2 und 3 miteinander in Verbindung steht. Auf diese Weise kann das über den nicht gezeichneten Vorlauf zuströmende Heizmedium in das Rohr 1 eintreten, sich auf die waagerecht verlaufenden Rohre 3 verteilen und anschließend wieder in das senkrechte Rohr 2 eintreten, aus dem es über den ebenfalls nicht gezeichneten Rücklauf in das Heizungssystem zurückgeführt wird. Zum Anschluß an Vor- und Rücklauf sind die unteren Enden der Rohre 1 und 2 mit entsprechenden Armaturen bzw. Fittings versehen, die der besseren Darstellung wegen auf der Zeichnung weggelassen worden sind.With their end pieces 3a, the horizontally extending tubes 3 are connected to the vertically extending tubes 1 and 2, so that the inside of the tubes 1, 2 and 3 is connected to one another. In this way, the heating medium flowing in via the feed line, not shown, can enter the pipe 1, be distributed over the horizontally extending pipes 3 and then enter the vertical pipe 2 again, from which it is returned to the heating system via the return line, also not shown . For connection to the flow and return, the lower ends of the pipes 1 and 2 are provided with corresponding fittings or fittings which have been omitted from the drawing for the sake of better illustration.

Um die Wärmeaustauschfläche des jeweiligen Heizkörpers bei vorgegebenem Abstand A zwischen den senkrechten Rohren 1 und 2, der werkseitig und durch den ortsfest verlegten Vor- und Rücklauf festgelegt ist, veränderlich ausführen zu können, kann die Gesamtlänge L der waagerecht verlaufenden, C-förmig ausgebildeten Rohre 3 verändert werden. Dies ist anhand eines Ausführungsbeispiels in Figur 2 dargestellt. Während mit ausgezogenen Linien ein Heizkörper nach Figur 1 gezeichnet ist, ist mit gestrichelten Linien angedeutet, daß die Länge L der Rohre auf die Länge L1 vergrößert werden kann, wenn sowohl das die beiden Rohrbögen 3b verbindende Rohrmittelstück 3c als auch die Endstücke 3a länger ausgeführt werden. Bei gleichem Abstand der senkrechten Rohre 1 und 2 und gleichbleibender Anzahl der insgesamt verwendeten waagerechten Rohre 3 ergibt sich somit eine entsprechend vergrößerte Wärmeaustauschfläche für den gestrichelt in Figur 2 dargestellten Heizkörper. Mit strichpunktierten Linien ist dargestellt, daß eine weitere Vergrößerung der Rohrlänge der Rohre 3 auf den Wert L2 möglich ist, ohne daß hierfür der Abstand A bzw. die Länge der senkrechten Rohre 1 und 2 verändert werden müssen. Da die waagerechten Rohre 3 stets mit ihren Endstücken 3a an die senkrechten Rohre 1 und 2 angeschlossen sind, werden die Rohre 3 auf ihrer gesamten Länge von Heizmedium durchflossen.In order to be able to change the heat exchange surface of the respective radiator at a predetermined distance A between the vertical pipes 1 and 2, which is fixed in the factory and by the fixed flow and return, the total length L of the horizontally running, C-shaped pipes can 3 can be changed. This is shown in FIG. 2 using an exemplary embodiment. While a radiator according to FIG. 1 is drawn with solid lines, it is indicated with dashed lines that the length L of the pipes can be increased to the length L1 if both the pipe center piece 3c connecting the two pipe bends 3b and the end pieces 3a are made longer . With the same Distance between the vertical tubes 1 and 2 and a constant number of the horizontal tubes 3 used in total results in a correspondingly increased heat exchange surface for the radiator shown in dashed lines in FIG. With dash-dotted lines it is shown that a further increase in the tube length of the tubes 3 to the value L2 is possible without the distance A or the length of the vertical tubes 1 and 2 having to be changed. Since the horizontal pipes 3 are always connected with their end pieces 3a to the vertical pipes 1 and 2, the pipes 3 are flowed through by heating medium over their entire length.

Wie aus den Figuren 1 und 2 weiterhin hervorgeht, sind die Endstücke 3a der waagerechten Rohre 3 mit der Rückseite der senkrechten Rohre 1 und 2 verbunden. Hierdurch ist es möglich, diese Verbindung mittels einer Kreuzlochpreßschweißung vorzunehmen, die besonders einfach und mit hoher Zuverlässigkeit herstellbar ist. Die Figur 4 zeigt, daß die Endstücke 3a selbstverständlich auch mit der Vorderseite der Rohre 1 und 2 verbunden sein können und daß es vorteilhaft sein kann, den unteren, die Anschlüsse enthaltenden Teil der senkrecht verlaufenden Rohre 1 und 2 durch eine Verkleidung 4 abzudecken, die auf einfache Weise auf die senkrechten Rohre 1 und 2 aufgesetzt wird.As can also be seen from FIGS. 1 and 2, the end pieces 3a of the horizontal pipes 3 are connected to the rear of the vertical pipes 1 and 2. This makes it possible to make this connection by means of cross-hole pressure welding, which can be produced particularly easily and with high reliability. Figure 4 shows that the end pieces 3a can of course also be connected to the front of the tubes 1 and 2 and that it can be advantageous to cover the lower part of the vertically extending tubes 1 and 2 containing the connections by a covering 4 which is simply placed on the vertical tubes 1 and 2.

Bei dem in Figur 3 dargestellten Ausführungsbeispiel sind die senkrechten Rohre 1 und 2 auf ihrer gesamten Länge mit einer tafelartigen Verkleidung 5 versehen, die wiederum auf die Vorderseite der Rohre 1 und 2 aufgesetzt und gegebenenfalls mit diesen verschweißt oder in anderer geeigneter Weise verbunden ist. Durch diese tafelartige Verkleidung 5 erhöht sich die am Wärmeaustausch teilnehmende Oberfläche. Da die Verkleidung 5 durch Wärmeleitung aufgeheizt wird, ist auf diese Weise nicht nur eine optische Veränderung des Heizkörpers, sondern eine Erhöhung seiner Wärmeleistung möglich.In the embodiment shown in Figure 3, the vertical tubes 1 and 2 are provided over their entire length with a panel-like covering 5, which in turn is placed on the front of the tubes 1 and 2 and optionally welded to them or connected in some other suitable way. This panel-like covering 5 increases the surface participating in the heat exchange. Since the casing 5 is heated by heat conduction, not only an optical change of the radiator, but an increase in its heat output is possible in this way.

Die Figuren 5 bis 8 zeigen vier weitere Ausführungsmöglichkeiten erfindungsgemäßer Heizkörper. Der Unterschied zwischen den Heizkörpern nach den Figuren 5 und 6 besteht in der Länge der waagerechten Rohre 3, beim Ausführungsbeispiel nach Figur 7 sind insgesamt drei Gruppen gleich langer Rohre 3 angeordnet, die voneinander in unterschiedlichem Abstand liegen. Die Figur 8 zeigt eine Ausführungsform mit zwei Gruppen waagerechter Rohre 3. Während die Rohre 3 innerhalb einer Gruppe gleich lang sind, ist die Länge der Rohre 3 in den beiden Gruppen unterschiedlich ausgeführt.FIGS. 5 to 8 show four further design options for radiators according to the invention. The difference between the radiators according to FIGS. 5 and 6 is the length of the horizontal pipes 3; in the exemplary embodiment according to FIG. 7, a total of three groups of pipes 3 of the same length are arranged, which are at different distances from one another. FIG. 8 shows an embodiment with two groups of horizontal tubes 3. While the tubes 3 are of the same length within one group, the length of the tubes 3 in the two groups is different.

Auch die Figuren 9 bis 12 zeigen weitere Ausführungsmöglichkeiten. Der Heizkörper nach Figur 9 besitzt die größtmögliche Wärmeaustauschfläche; der Heizkörper nach Figur 10 verwendet Rohre 3 mit drei unterschiedlichen Rohrlängen, die in gleichbleibendem Abstand zueinander angeordnet sind. Daß die Rohre 3 nicht nur gruppenweise mit unterschiedlicher Länge ausgeführt werden können, zeigen die Figuren 11 und 12, aus denen auch hervorgeht, daß sich durch die Verwendung unterschiedlich langer Rohre 3 das Erscheinungsbild der Heizkörper stark verändern läßt.Figures 9 to 12 also show other possible embodiments. The radiator according to Figure 9 has the largest possible heat exchange area; 10 uses tubes 3 with three different tube lengths which are arranged at a constant distance from one another. FIGS. 11 and 12 show that the pipes 3 can not only be designed in groups with different lengths, from which it can also be seen that the use of pipes 3 of different lengths can greatly change the appearance of the radiators.

Auf den Figuren 13 und 14 ist schließlich ein weiteres Ausführungsbeispiel dargestellt. Bei diesem Heizkörper sind die Rohrbögen 3b eines der waagerechten Rohre 3 mit einem größeren Biegeradius als die Rohrbögen 3b der restlichen Rohre 3 ausgeführt. Hierdurch liegt das Rohrmittelstück 3c dieses Rohres 3 räumlich vor den Rohrmittelstücken 3c der anderen Rohre 3. Es ist hierdurch besonders geeignet, um an diesem vorstehenden Rohrmittelstück 3c Wäschestücke zum Trocknen aufzuhängen. Aus der Draufsicht in Figur 14 geht besonders deutlich hervor, daß eines der Rohrmittelstücke 3c vor der Ebene liegt, in der sich die anderen Rohrmittelstücke 3c befinden.Finally, another exemplary embodiment is shown in FIGS. 13 and 14. In this radiator, the pipe bends 3b of one of the horizontal pipes 3 are designed with a larger bending radius than the pipe bends 3b of the remaining pipes 3. As a result, the pipe center piece 3c of this pipe 3 lies spatially in front of the pipe center pieces 3c of the other pipes 3. It is hereby particularly suitable for hanging laundry items to dry on this projecting pipe center piece 3c. It is particularly clear from the top view in FIG. 14 that one of the pipe center pieces 3c lies in front of the plane in which the other pipe center pieces 3c are located.
