Abstract
Description
Die Erfindung betrifft einen Wärmeübertrager, der als Rohrschlange aus Rippenrohr ausgebildet ist und dessen Innenraum von dem von einem Brenner abgegebenen Abgas vertikal von oben nach unten durchströmt wird, wobei das Abgas Wärme an die durch die Rohrschlange fließende Flüssigkeit abgibt.The invention relates to a heat exchanger, which is designed as a coil of finned tube and its interior of the exhaust gas emitted by a burner vertically from top to bottom flows through being, the exhaust gas heat to the liquid flowing through the coil.
Stand der TechnikState of the art
Bei den für Heizgeräte verwendeten Wärmeübertragern ist der Brenner über die Rohrschlange angeordnet und das abgegebene Abgas durchströmt den Innenraum der Rohrschlange von oben nach unten. Dabei bildet sich an der Rohrschlange mehr oder weniger Kondensat, das gerade im brennernahen Bereich der Rohrschlange besonders sauer ist und auf die von Brenner weiter entfernten Teile der Rohrschlange und Rippen tropft. Dadurch wird nicht nur der gesamte Bereich des Wärmeübertragers der Korrosion ausgesetzt, darunter leidet auch die Wärmeübertragung im Wärmeübertrager und damit dessen Wirkungsgrad.For the heat exchangers used for heating devices is the burner over the coil is arranged and the exhaust gas emitted flows through the interior the pipe coil from top to bottom. This forms on the pipe coil more or less condensate, especially in the area close to the burner the pipe coil is particularly acidic and continues to that of burner removed parts of the coil and fins dripping. This will not only the entire area of the heat exchanger exposed to corrosion, this also affects heat transfer in the heat exchanger and thus its efficiency.
Es ist Aufgabe der Erfindung, bei einem in einem Heizgerät mit einem Wärmeübertrager der eingangs erwähnten Art die negativen Einflüsse des sauren Kondensats auszuschalten und die Wärmeübertragung an der Rohrschlange zu verbessern.It is an object of the invention to one in a heater with a heat exchanger the one mentioned at the beginning Kind of the negative influences turn off the acidic condensate and heat transfer to the coil to improve.
Vorteile der ErfindungAdvantages of invention
Diese Aufgabe wird nach der Erfindung dadurch gelöst, dass zumindest bei einem Teil der dem Brenner zugekehrten Windungen der Rohrschlange die tiefsten Punkte der Rippen mit einem Kondensat-Ableiter verbunden sind, dessen unteres Ende außerhalb der vertikalen Projektion der Rohrschlange liegt.This object is achieved according to the invention solved by that at least part of the turns facing the burner the lowest point of the fins with a condensate drain are connected, the lower end of which is outside the vertical projection the pipe coil lies.
Diese Verbindung der Rippen im brennernahen Bereich der Rohrschlange mittels eines Kondensat-Ableiters sorgt dafür, dass das in diesem Bereich auskondensierende Kondensat aus diesem Bereich abfließen und außerhalb der Rohrschlange abgeleitet werden kann. Das Kondensat tropft nicht mehr auf darunter angeordnete Teile der Rohrschlange und beeinträchtigt die Wärmeübertragung in diesem Bereich der Rohrschlange nicht mehr. Die Lebensdauer des Wärmeübertragers und sein Wirkungsgrad werden merklich verbessert.This connection of the ribs near the burner Area of the pipe coil by means of a condensate drain for this, that the condensate condensing out in this area from this Drain area and outside the coil can be derived. The condensate does not drip more on parts of the pipe coil arranged underneath and affects the heat transfer no longer in this area of the coil. The lifespan of the heat exchanger and its efficiency is markedly improved.
In der einfachsten Weise kann der Kondensat-Ableiter als Draht ausgebildet sein, an dem das Kondensat entlangfließt und an dem unteren Ende außerhalb der Rohrschlange einer Kondensat-Auffang- oder Kondensat-Ableit-Einrichtung zugeführt wird.In the simplest way, the Condensate drain can be designed as a wire on which the condensate along flows and outside at the lower end the coil of a condensate trap or condensate discharge device is fed.
Die Ausgestaltung kann jedoch auch so vorgenommen sein, dass der Kondensat-Ableiter als schmaler Metallstreifen ausgebildet ist, der wannenförmig zu den Rippen hin gewölbt ist. Das auf den Kondensat-Ableiter tropfende Kondensat kann dann in der Art einer Auffangwanne aus dem Bereich der Rohrschlange weitergeleitet werden.However, the design can also be made so that the condensate drain as a narrow metal strip is formed, the trough-shaped arched towards the ribs is. The condensate dripping onto the condensate drain can then enter the type of a collecting pan forwarded from the area of the pipe coil become.
Ist vorgesehen, dass zumindest die Rippen der dem Brenner zugekehrten Windungen der Rohrschlange mit einem diesen Windungen zugeordneten, einzigen Kondensat-Ableiter versehen sind, dann kann in diesen Bereich der Rohrschlange das Kondensat abgeleitet werden.It is envisaged that at least the Ribs of the coils of the pipe coil facing the burner a single condensate drain assigned to these windings are provided, then the condensate can be in this area of the coil be derived.
Die Anbringung des Kondensat-Ableiters wird nach einer Ausgestaltung dadurch vereinfacht, dass zumindest der Anfang und das Ende des Kondensat-Ableiters mit einigen, zugekehrten Rippen der Rohrschlange verbunden sind.The condensate drain is attached simplified according to an embodiment in that at least the Start and end of the condensate drain with some facing Ribs of the coil are connected.
Die Weiterbildung zum Heizgerät sieht vor, dass der Brenner und die Rohrschlange in einem Gehäuse untergebracht sind, das unterhalb der Rohrschlange eine Abgaskammer mit Abgasausgang bildet. Dabei ist aus Gründen der ungestörten Strömung des Abgases vorgesehen, dass die Rippen an den Windungen der Rohrschlange vertikal und damit in Strömungsrichtung des Abgases ausgerichtet sind.Continuing education on heater looks before that the burner and the coil are housed in one housing are, below the pipe coil an exhaust chamber with exhaust outlet forms. It is for reasons the undisturbed flow of the exhaust gas provided that the fins on the coils of the coil vertical and thus in the direction of flow of the exhaust gas are aligned.
In jedem Fall ist es besonders wichtig, dass die Rohrschlange und die Rippen aus gut wärmeleitendem Werkstoff, insbesondere Metall, bestehen, um einen guten Wirkungsgrad der Wärmeübertragung zu erhalten.In any case, it is particularly important that the coil and the fins made of a good heat-conducting material, in particular Metal, exist to ensure good heat transfer efficiency to obtain.
