Description

Die Erfindung bezieht sich auf einen Wärmetauscher, insbesondere Radiator, mit einem oberen und einem unteren horizontalen Sammelrohr und dazwischen angeordneten, die Sammelrohre miteinander verbindenden Steigrohren, an die vorzugsweise Wärmeaustauschstege angeformt sind, wobei mindestens eines der Sammelrohre als Doppelrohr ausgeführt ist bzw. sind.The invention relates to a heat exchanger, in particular a radiator, with an upper and a lower horizontal header pipe and riser pipes which are arranged between them and connect the header pipes to one another and to which heat exchange webs are preferably formed, at least one of the header pipes being or being designed as a double pipe.

Charakteristik des bekannten Standes der TechnikCharacteristic of the known prior art

Derartige Wärmetauscher, die insbesondere als Radiatoren bei Zentralheizungen eingesetzt werden, werden im allgemeinen aus stranggepreßten Leichtmetallprofilen hergestellt, wobei die beiden Sammelrohre von je einem einzelnen rohr gebildet werden.Such heat exchangers, which are used in particular as radiators in central heating systems, are generally produced from extruded light metal profiles, the two collecting tubes being formed from a single tube each.

Aus der DE-A-28 32 961 ist ein derartiger Wärmetauscher bekannt, bei dem die Doppelrohre nebeneinander liegen.Such a heat exchanger is known from DE-A-28 32 961, in which the double tubes lie side by side.

Aufgabe und Wesen der ErfindungObject and nature of the invention

Aufgabe der Erfindung ist es, einen Wärmetauscher der eingangs erwähnten Art zu schaffen, bei dem das Entlüften in größeren Zeitabständen als bei herkömmlichen Wärmetauschern erfolgen kann, und bei dem weiters eine Rohrleitung des Sammelrohres, im Falle, daß der Wärmetauscher als Einzelheizkörper verwendet wird, der nicht an ein System angeschlossen ist, als Expansionsrohr fungieren kann.The object of the invention is to provide a heat exchanger of the type mentioned, in which the ventilation can be carried out at greater time intervals than in conventional heat exchangers, and in addition a pipe of the header pipe, in the event that the heat exchanger is used as a single radiator, the is not connected to a system, can act as an expansion pipe.

Dies wird erfindungsgemäß dadurch erreicht, daß das obere Sammelrohr als Doppelrohr ausgeführt ist, dessen Rohrleitungen übereinander liegen und durch Löcher in der Trennwand oder mittels stirnseitig angeschlossener Verbindungsmuffen miteinander verbunden sind.This is achieved according to the invention in that the upper header pipe is designed as a double pipe, the pipes of which lie one above the other and are connected to one another by holes in the partition or by means of connecting sleeves connected at the end.

Vorteilhaft ist vorgesehen, daß die Löcher kleiner sind als der Leitungsquerschnitt der Steigrohre.It is advantageously provided that the holes are smaller than the line cross section of the risers.

Selbstverständlich ist eine Entlüftung nach wie vor notwendig, jedoch kann beispielsweise die Zeitspanne zwischen den einzelnen Entlüftungen auf das 5- bis 10-fache erweitert werden. Beim Durchfluß des Wärmeträgermediumwassers durch die untere Rohrleitung des oberen Sammelrohres steigen die Gase durch die Löcher in die obere Rohrleitung des Doppelrohres auf, so daß der Durchfluß im unteren Leitungsrohr wesentlich länger frei bleibt als bei herkömmlichen Radiatoren.Of course, venting is still necessary, but the time between the individual venting can be extended by 5 to 10 times, for example. When the heat transfer medium water flows through the lower pipe of the upper manifold, the gases rise through the holes in the upper pipe of the double pipe, so that the flow in the lower pipe remains free much longer than with conventional radiators.

Vorteilhaft ist vorgesehen, daß jedem Steigrohr ein Loch in der Trennwand gegenüberliegt.It is advantageously provided that each riser pipe is opposite a hole in the partition.

Für die Entlüftung hat es sich als besonders vorteilhaft erwiesen, wenn die Löcher kreisförmig, mit einem Durchmesser von ca. 5 mm sind.For ventilation, it has proven to be particularly advantageous if the holes are circular and have a diameter of approximately 5 mm.

Ein Ausführungsbeispiel der Erfindung sieht vor, daß das Doppelrohr des Sammelrohres sich aus einem Rohr, das integrierter Bestandteil des Radiators, und einem rohr, das integrierter Bestandteil einer Radiatorverkleidung ist, zusammensetzt, wobei die Rohre vorteilhaft mittels angeformter Klemmhaken miteinander verbunden sind.An embodiment of the invention provides that the double tube of the header tube is composed of a tube, which is an integral part of the radiator, and a tube, which is an integral part of a radiator casing, the tubes being advantageously connected to one another by means of molded-on clamping hooks.

Ein weiteres vorteilhaftes Ausführungsbeispiel der Erfindung sieht vor, daß das oder die Doppelrohre der Sammelrohre einstückig ausgeführt und beispielsweise aus Aluminium stranggepreßt oder gezogen sind.Another advantageous embodiment of the invention provides that the double pipe or pipes of the header pipes are made in one piece and are extruded or drawn, for example, from aluminum.

Nachstehend wird die Erfindung an Hand der Figuren der beiliegenden Zeichnung eingehend beschrieben.The invention is described in detail below with reference to the figures in the accompanying drawing.

  • FIG. 3 shows the same section through a second exemplary embodiment of the invention.

Beschreibung von bevorzugten AusführungsbeispielenDescription of preferred embodiments

Der erfindungsgemäße Wärmetauscher bzw. Radiator besteht aus je einem oberen und unteren Sammelrohr 1 und dazwischen angeordneten Steigrohren 2, an die zur besseren Wärmeabgabe Stege angeformt sind. Wie aus den Fig. 2 und 3 ersichtlich, münden die Steigrohre 2 bei Öffnungen 3 in die untere Rohrleitung 4 des oberen Sammelrohres 1, das als Doppelrohr ausgeführt ist.The heat exchanger or radiator according to the invention consists of an upper and lower header pipe 1 and riser pipes 2 arranged between them, to which webs are molded for better heat dissipation. As can be seen from FIGS. 2 and 3, the risers 2 open at openings 3 in the lower pipe 4 of the upper header 1, which is designed as a double pipe.

Dieses Doppelrohr weist somit zwei Rohrleitungen 4, 5 auf.This double pipe thus has two pipes 4, 5.

Die Rohrleitungen 4, 5 sind mittels Löcher 6 miteinander verbunden, die eine Lochreihe bilden, und wobei sich im Ausführungsbeispiel gegenüber jeder Öffnung 3 für den Anschluß eines Steigrohres 2 ein Loch 6 befindet. Die Löcher haben einen Durchmesser von ca. 5 mm.The pipes 4, 5 are connected to one another by means of holes 6, which form a row of holes, and in the exemplary embodiment there is a hole 6 opposite each opening 3 for connecting a riser pipe 2. The holes have a diameter of approx. 5 mm.

An die obere Rohrleitung 5 des oberen Sammelrohres 1 ist ein Entlüfternippel 7 angeschlossen.A venting nipple 7 is connected to the upper pipeline 5 of the upper manifold 1.

Jede Rohrleitung hat vorzugsweise einen Durchmesser von 12,7 mm (1/2 Zoll), dies trifft sowohl für das obere als auch für das untere Sammelrohr 1 zu.Each pipe preferably has a diameter of 12.7 mm (1/2 inch), this applies to both the upper and the lower header pipe 1.

In der Fig. 1 ist schraffiert angedeutet, wie durch das erfindungsgemäße Sammelrohr 1 die vom Wärmeübertragungsmedium abgegebenen Gase im Sammelrohr 1 gespeichert werden.In Fig. 1 it is indicated by hatching how the gases emitted by the heat transfer medium are stored in the collecting pipe 1 by the collecting pipe 1 according to the invention.

Dadurch, daß sich die obere Rohrleitung 5 praktisch zur Gänze füllen kann, bevor es zu einer Unterbrechung des Flusses des Wärmeübertragungsmediums in der unteren Rohrleitung 4 kommt, kann die Zeitspanne zwischen den Entlüftungen, wie die Praxis gezeigt hat, bis auf das 5- bis 10-fache und mehr ausgedehnt werden.Because the upper pipeline 5 can practically fill completely before there is an interruption in the flow of the heat transfer medium in the lower pipeline 4, the time between the vents, as practice has shown, can be reduced to 5-10 -fold and more to be expanded.

Im Ausführungsbeispiel nach der Erfindung ist im unteren Sammelrohr 1, und zwar in dessen unterer Rohrleitung 5, ein elektrischer Heizstab 8 eingesetzt.In the exemplary embodiment according to the invention, an electric heating element 8 is inserted in the lower collecting pipe 1, specifically in the lower pipe 5 thereof.

Die Rohrleitungen 4, 5 des unteren Sammelrohres 1 sind beidseitig durch stirnseitige Anschlußmuffen 9 miteinander verbunden. Wird das Vorlaufventil A des Radiators, das vorzugsweise ein Magnetventil ist, geschlossen und somit der Radiator von der Heizanlage getrennt, kann dieser als Einzelheizkörper eingesetzt werden.The pipes 4, 5 of the lower header pipe 1 are connected to one another on both sides by connecting sleeves 9 on the end face. If the flow valve A of the radiator, which is preferably a solenoid valve, is closed and the radiator is thus separated from the heating system, it can be used as an individual radiator.

Die Fig. 3 zeigt ein Ausführungsbeispiel, bei dem das Doppelrohr des oberen Sammelrohres 1 von zwei Einzelrohren gebildet wird, und zwar ist das Rohr für die Rohrleitung 5' integrierter Bestandteil einer Radiatorabdeckung 10, während das Rohr für die Rohrleitung 4' integrierter Bestandteil des eigentlichen Radiators ist, in das auch die Steigrohre 2 münden. Beide Einzelrohre 4, 5 sind mittels Klemmhaken 11 miteinander verbunden, stirnseitig mittels einer nicht gezeigten Verbindungsmuffe, sodaß sie ein zusammenwirkendes Doppelrohr ergeben.Fig. 3 shows an embodiment in which the double tube of the upper header 1 is formed by two individual tubes, namely the tube for the pipe 5 'is an integral part of a radiator cover 10, while the pipe for the pipe 4' is an integral part of the actual Radiators is, in which the risers 2 open. Both individual pipes 4, 5 are connected to one another by means of clamping hooks 11, on the end face by means of a connecting sleeve, not shown, so that they result in a cooperating double pipe.
