Definitions
- the invention relates to a heat exchanger, in particular for cooling noise gases from stoves, stoves, fireplace kits, pellet stoves and similar fireplaces, hereinafter simply called stoves, according to the preamble of claim 1.
- the aim of the invention is to achieve an increase in efficiency and, in one embodiment, to provide the possibility of also heating an adjoining room with the stove.
- the flue gases are led around at least one pipe in a screw-shaped flue gas duct before they are introduced into the chimney. They heat the ambient air on the outside of the screw and the air in the at least one tube, which either gets into the environment or is discharged into a warm air duct for other use.
- the invention is illustrated in the drawing, purely schematically, using an exemplary embodiment.
- Fig. 1 is shown in its entirety with 7 heat exchanger resting on an oven 8 in perspective. Cooling fins 6 on the housing 11, which cool the heat exchanger 7, on the other hand heat the ambient air and have received their designation from the perspective of the heat exchanger 7, are clearly visible.
- the arrow 5 points to the opening of the convection tube 5, which runs horizontally in the example shown.
- the Fig. 2 shows the internal structure of the heat exchanger 7: starting from this lower part and with the rear or front end wall and in some cases also connected to one another, separating plates 3 and baffles 4 are arranged on a lower part 1, which have the flue gases which have their inlet 9 centrally below , lead helically around the convection tube 5 to the left and right. After leaving the heat exchanger, the flue gas arrives, respectively left and right, to an outlet 10 and into a flue gas duct, from there into the exhaust pipe and subsequently into the chimney.
- the arrangement of the outlet and the connection to the fireplace must be adapted depending on the installation situation.
- a cover 2 is placed on this construction and closes the flue gas ducts appropriately. Like the front wall and possibly the rear wall, it has the cooling fins 6.
- a horizontal convection tube 5 is integrated in the lower part 1, the separating plates 3 and the guide plates 4 are at least substantially gas-tightly connected to it, so that the flue gas ducts flow through the heat exchanger in an approximately helical, if not round, manner.
- the convection tube 5 does not have to be square, it can also have a different geometry, for example a circular cross section, regardless of which it can be of split design in order to achieve a plurality of warm air flows.
- the lower part with the horizontal convection pipe in the longitudinal axis, the separating plates, the baffle plates and the cover, results in a hollow body with several channels that spiral around the horizontal convection pipe, the path of the flue gas is indicated by the arrows.
- the flue gas is set into a very strong rotation with strong centrifugal force through these channels, which lead around the horizontal convection tube.
- the high centrifugal force creates a strong friction of the heating gas on the outer surfaces of the hollow body (turbulent flow) and so there is a very strong heat transfer from the heating gas to the outer surface of the heat exchanger and from there via the cooling fins to the ambient air.
- the heating gas flows through the heat exchanger from the center to the edges on the left and right. About 50% of the heating gas flows through the heat exchanger from the center to the right side and about 50% of the heating gas flows through the heat exchanger from the center to the left side.
- the heating gas could also flow through the heat exchanger from left to right or from right to left.
- a warm air line can optionally be connected to the horizontal convection pipe at the left or right end, through which hot air is extracted from the heat exchanger with the aid of a fan (not shown) and slides into other rooms.
- the invention can be modified in various ways, so the heat exchanger 7 does not have to be positioned above the combustion chamber, it can also be located at another location, for example on the side of the combustion chamber or on the back of the combustion chamber. be arranged.
- the flue gas does not need to be divided, but can be guided helically in one direction.
- the convection pipe does not have to lie exactly in the center of the heat exchanger, it does not have to run exactly straight, and it can, especially with one-sided flow through the heat exchanger, be inclined or, depending on the situation at the installation location, also run vertically in order to achieve natural convection in the convection pipe .
- a heat exchanger according to the invention can be used both in a pellet stove and in a stove, in a stove or a fireplace kit or another stove.

Abstract
Die Erfindung betrifft einen Wärmetauscher zur Abkühlung der Rauchgase eines Ofens (8) und der Erwärmung der umgebenden Raumluft.The invention relates to a heat exchanger for cooling the flue gases of a furnace (8) and for heating the surrounding room air.
Zur Erhöhung des Wirkungsgrades ist vorgesehen, dass der Wärmetauscher in einem Gehäuse einen Rauchgaseintritt (9) für das Rauchgas des Ofens (8) aufweist, dass im Inneren des Gehäuses (11) ein Konvektionsrohr (5) angeordnet ist, und dass Trennbleche (3) und Leitbleche (4) zwischen den Innenseiten des Gehäuses und der Außenseite des Konvektionsrohrs (5) angeordnet sind, durch die das Rauchgas im Inneren des Gehäuses (11) schraubförmig um das Konvektionsrohr (5) zu zumindest einem Rauchgasauslass (10) geführt wird.
Description
Die Erfindung betrifft einen Wärmetauscher, insbesondere zur Abkühlung von Rauschgasen von Kaminöfen, Herden, Kaminbausätzen, Pelletöfen und ähnlichen Feuerstellen, im Folgenden einfach Öfen genannt, entsprechend dem Oberbegriff des Anspruches 1.The invention relates to a heat exchanger, in particular for cooling noise gases from stoves, stoves, fireplace kits, pellet stoves and similar fireplaces, hereinafter simply called stoves, according to the preamble of
Bei derartigen Feuerstellen besteht ein Bedarf an der besseren Nutzung des Brennstoffes, gleichbedeutend mit der Reduzierung der Temperatur der Rauchgase beim Eintritt in den Kamin, gleichbedeutend mit einer Erhöhung des Wirkungsgrades des Ofens. Auch besteht oft der Wunsch, mit dem Ofen auch ein Nachbarzimmer zu heizen, was im Stand der Technik nicht möglich ist.In such fireplaces, there is a need for better use of the fuel, which is synonymous with reducing the temperature of the flue gases as they enter the chimney, which also means increasing the efficiency of the furnace. There is also often the desire to heat a neighboring room with the stove, which is not possible in the prior art.
Die Erfindung hat das Ziel, eine Erhöhung des Wirkungsgrads zu erreichen und in einer Ausgestaltung die Möglichkeit zu schaffen, auch ein Nebenzimmer mit dem Ofen zu beheizen.The aim of the invention is to achieve an increase in efficiency and, in one embodiment, to provide the possibility of also heating an adjoining room with the stove.
Erfindungsgemäß wird dies durch die Merkmale des kennzeichnenden Teils des Anspruches 1 erreicht; mit anderen Worten, es werden die Rauchgase in einem schraubförmigen Rauchgaskanal um zumindest ein Rohr geführt, bevor sie in den Kamin eingeleitet werden. Dabei erwärmen sie an der Außenseite der Schraube die Umgebungsluft und im zumindest einen Rohr die darin befindliche Luft, die entweder in die Umgebung gelangt oder in einen Warmluftkanal zu anderwärtiger Nutzung abgeleitet wird.According to the invention this is achieved by the features of the characterizing part of
Dadurch wird ein hervorragender Wärmeübergang besonders auf der Außenseite des Rauchgaskanals erreicht, und es kann mittels einer Warmluftleitung mit Ventilator die im Rohr befindliche Warmluft in ein Nebenzimmer geführt werden, um dieses zu heizen.This achieves excellent heat transfer, especially on the outside of the flue gas duct, and the warm air in the pipe can be routed to an adjoining room by means of a warm air line with a fan in order to heat it.
Die Erfindung wird in der Zeichnung, rein schematisch, anhand eines Ausführungsbeispiels näher erläutert. Dabei zeigt die
In
Die
Ein Deckel 2 ist auf diese Konstruktion aufgesetzt und schließt die Rauchgaskanäle passend ab. Er weist, wie die Vorderwand und gegebenenfalls die Rückwand, die Kühlrippen 6 auf.A cover 2 is placed on this construction and closes the flue gas ducts appropriately. Like the front wall and possibly the rear wall, it has the cooling fins 6.
Im dargestellten Ausführungsbeispiel ist ein waagerechtes Konvektionsrohr 5 im Unterteil 1 integriert, die Trennbleche 3 und die Leitbleche 4 sind mit ihm zumindest im Wesentlichen gasdicht verbunden, sodass die Rauchgaskanäle etwa schraubförmig, wenn auch nicht rund, durch den Wärmetauscher strömen. Das Konvektionsrohr 5 muss nicht quadratisch sein, es kann auch eine andere Geometrie, beispielsweise einen kreisförmigen Querschnitt haben, unabhängig davon kann es geteilt ausgebildet sein, um mehrere Warmluftströme zu erzielen. Bei kreisförmigem (Gesamt-) Querschnitt könnten auch die Vorderwand, die Rückwand, gegebenenfalls der Oberteil und sogar der Unterteil entsprechend bauchig ausgebildet sein, wodurch die Rauchgaskanäle eine der klassischen Schraubenform besser angepasste Ausbildung bekommen. Aus fertigungstechnischen Gründen ist die dargestellte Form bevorzugt, doch ist dies letztlich eine Kostenfrage und keine technische Bevorzugung.In the exemplary embodiment shown, a horizontal convection tube 5 is integrated in the
Durch den Unterteil, mit dem waagerechten Konvektionsrohr in Längsachse, den Trennblechen, den Leitblechen und dem Deckel ergibt sich ein Hohlkörper mit mehreren spiralförmig, um das waagerechte Konvektionsrohr rundherumführenden Kanälen, der Weg des Rauchgases ist durch die Pfeile angedeutet.The lower part, with the horizontal convection pipe in the longitudinal axis, the separating plates, the baffle plates and the cover, results in a hollow body with several channels that spiral around the horizontal convection pipe, the path of the flue gas is indicated by the arrows.
Durch die Trennbleche 3 und die Leitbleche 4 werden einzelne Kammern gebildet und miteinander verbunden.Individual chambers are formed and connected to one another by the separating plates 3 and the guide plates 4.
Durch diese spiralförmig, um das waagerechte Konvektionsrohr rundherumführenden Kanäle wird das Rauchgas in eine sehr starke Rotation mit starker Fliehkraft versetzt. Durch die hohe Fliehkraft entsteht eine starke Reibung des Heizgases an den Außenflächen des Hohlkörpers (turbulente Strömung) und so kommt es zu einem sehr starken Wärmeübergang vom Heizgas an die Außenfläche des Wärmetauschers und von dort über die Kühlrippen an die Umgebungsluft.The flue gas is set into a very strong rotation with strong centrifugal force through these channels, which lead around the horizontal convection tube. The high centrifugal force creates a strong friction of the heating gas on the outer surfaces of the hollow body (turbulent flow) and so there is a very strong heat transfer from the heating gas to the outer surface of the heat exchanger and from there via the cooling fins to the ambient air.
Das Heizgas durchströmt beim dargestellten Ausführungsbeispiel den Wärmtauscher von der Mitte aus hin zu den Rändern links und rechts. Etwa 50% des Heizgases durchströmt den Wärmetauscher von der Mitte aus hin zur rechten Seite und etwa 50% des Heizgases durchströmt den Wärmetauscher von der Mitte aus hin zur linken Seite. Das Heizgas könnte den Wärmetauscher aber auch von links nach rechts oder von rechts nach links durchströmen.In the exemplary embodiment shown, the heating gas flows through the heat exchanger from the center to the edges on the left and right. About 50% of the heating gas flows through the heat exchanger from the center to the right side and about 50% of the heating gas flows through the heat exchanger from the center to the left side. The heating gas could also flow through the heat exchanger from left to right or from right to left.
An dem waagerechten Konvektionsrohr kann, am linken oder rechten Ende, optional eine Warmluftleitung angeschlossen werden, durch die heiße Luft aus dem Wärmetauscher unter Zuhilfenahme eines Ventilators (nicht dargestellt) abgesaugt und in andere Räume gleitet wird.A warm air line can optionally be connected to the horizontal convection pipe at the left or right end, through which hot air is extracted from the heat exchanger with the aid of a fan (not shown) and slides into other rooms.
Die Erfindung kann verschiedentlich abgewandelt werden, so muss der Wärmetauscher 7 nicht oberhalb der Brennkammer positioniert werden, er kann auch an einer anderen Stelle, etwa seitlich an der Brennkammer oder an der Rückseite der Brennkammer, angeordnet sein. Wie bereits angeführt, braucht das Rauchgas nicht geteilt werden, sondern kann in einer Richtung schraubförmig geführt werden. Das Konvektionsrohr muss nicht genau mittig im Wärmetauscher liegen, es muss nicht genau geradlinig verlaufen, und es kann, insbesondere bei einseitiger Durchströmung des Wärmetauschers, geneigt oder, je nach Situation an der Einbaustelle, auch vertikal verlaufen, um zu natürlicher Konvektion im Konvektionsrohr zu kommen.The invention can be modified in various ways, so the
Ein erfindungsgemäßer Wärmetauscher kann sowohl bei einem Pelletofen als auch bei einem Kaminofen, bei einem Herd oder einem Kaminbausatz oder einem anderen Ofen verwendet werden.A heat exchanger according to the invention can be used both in a pellet stove and in a stove, in a stove or a fireplace kit or another stove.
Die erfindungsgemäß erzielbaren Vorteile sind:
- Der Wärmetauscher ist, wenn er oberhalb der Brennkammer positioniert wird, an der heißersten Stelle des Ofens positioniert, die Zufuhr der Rauchgase ist einfach zu bewerkstelligen;
- Durch die starke Rotation und Fliehkraft der Rauchgase kommt es zu stark turbulenter Strömung und damit zu einem starken Wärmeübergang vom Rauchgas an die Umgebungsluft, dadurch hat der Wärmetauscher einen hohen Wirkungsgrad bei geringster Baugröße;
- Durch das Konvektionsrohr 5 im Inneren des
Wärmetauchers 7, bevorzugt in seiner Längsachse, kann sehr heiße Luft abgesaugt und in andere Räume gleitet werden. - Durch die Anzahl der Kammern, durch die Anordnung und Zahl der Trennbleche bestimmt, kann der Wärmetauscher einfach, und ohne seinen modularen Charakter zu verlieren, optimal an die Heizleistung des Ofens angepasst werden;
- Eine Über- oder Unterdimensionierung des Wärmetauschers in Bezug auf die Heizleistung des Ofens kann durch passende Wahl der Anzahl der Trennbleche leicht vermieden werden.
- The heat exchanger, when positioned above the combustion chamber, is positioned at the hottest point in the furnace, the flue gas supply is easy to manage;
- Due to the strong rotation and centrifugal force of the flue gases, there is a strong turbulent flow and thus a strong heat transfer from the flue gas to the ambient air, which means that the heat exchanger has a high degree of efficiency with the smallest size;
- Very hot air can be drawn off through the convection tube 5 inside the
heat exchanger 7, preferably in its longitudinal axis, and can be slid into other rooms. - Due to the number of chambers, the arrangement and number of separating plates, the heat exchanger can be easily and optimally adapted to the heating capacity of the furnace without losing its modular character;
- An oversizing or undersizing of the heat exchanger in relation to the heating output of the furnace can easily be avoided by choosing the right number of dividers.
