Description

Die Erfindung betrifft ein Heizgerät nach dem Oberbegriff des Patentanspruchs 1. Ein solches Heizgerät ist z.B. aus der EP 1 039 246 A2 bekannt.The invention relates to a heater according to the preamble of claim 1. Such a heater is for example from the EP 1 039 246 A2 known.

Ein weiteres Heizgerät ist beispielsweise aus der DE 100 26 549 C1 oder der DE 101 14 490 C1 bekannt. Dieses Heizgerät besteht aus einem schraubenförmig gewendelten Wärmetauscher, in Fachkreisen Inox-Radial-Heizfläche genannt. Ferner weist das Heizgerät eine zylindrische Brennkammer auf, die axial von einem vorderen und einem hinteren Deckelelement (sogenannte Front- und Rückplatine) und radial vom Wärmetauscher begrenzt ist. An einem der beiden Platinen ist darüber hinaus ein Brenner für flüssige oder gasförmige Brennstoffe (Öl oder Gas) angeordnet. Schließlich umfasst ein Gehäuse, das aus einem Mantelteil, sogenannter Abgasmantel, und den beiden Platinen gebildet ist, den Wärmetauscher unter Ausbildung eines Abgaskanals.Another heater is for example from the DE 100 26 549 C1 or the DE 101 14 490 C1 known. This heater consists of a helical coiled heat exchanger, known in the art as Inox Radial Heating Surface. Further, the heater has a cylindrical combustion chamber, which is axially bounded by a front and a rear cover element (so-called front and rear circuit board) and radially from the heat exchanger. On one of the two boards, moreover, a burner for liquid or gaseous fuels (oil or gas) is arranged. Finally, a housing which is formed from a jacket part, so-called exhaust jacket, and the two boards, the heat exchanger to form an exhaust passage.

Die Einbindung des Wärmetauschers erfolgt bei diesem Heizgerät durch Verschweißen mit den stirnseitigen Platinen, in die zum Ausgleich der Steigung der Wendel eine entsprechende Vertiefung eingepresst wird. Der offene Strömungsquerschitt des Wärmetauschers endet somit jeweils an den Platinen. Um einen geschlossenen Kreislauf für das den Wärmetauscher durchströmende Heizwasser zu bilden, sind beidseitig (front- und rückseitig) zwei weitere Platinen erforderlich, an die dann jeweils ein Anschlußstutzen zur Verbindung mit dem hausseitigen Heizkreis angeschweißt ist. Weitere Einzelheiten sind weiter unten anhand einer zeichnerischen Darstellung dieses Standes der Technik erläutert.The integration of the heat exchanger takes place in this heater by welding with the end-side boards, in which a corresponding depression is pressed to compensate for the pitch of the helix. The open flow cross section of the heat exchanger thus ends in each case at the boards. In order to form a closed circuit for the heating water flowing through the heat exchanger, two further boards are required on both sides (front and back), to each of which then a connecting piece is welded for connection to the house-side heating circuit. Further details are explained below with reference to a drawing of this prior art.

Dieses Heizgerät hat sich hinsichtlich seiner Funktion und Betriebssicherheit an sich bestens bewährt und auch auf dem Markt etabliert. Insbesondere fertigungstechnisch bestehen aber folgende Nachteile:This heater has proven itself in terms of its function and reliability in itself and well established in the market. In particular, manufacturing technology, however, have the following disadvantages:

Die Platinen sind relativ kostenintensiv, da zumindest für die jeweils innere aus Korrosionsgründen ein hochwertiger Edelstahl verwendet werden muss. Darüber hinaus ist der Materialverschnitt recht hoch, da die angenähert runden Platinen aus eckigem vormaterial ausgestanzt werden. Bei den beiden brennerseitigen Deckelelementen kommt noch der Verschnitt für die Brenneröffnung hinzu. Schließlich ist beim Verschweißen zum Einspannen der brennerseitigen Doppelplatine ein recht großer Einspannbereich erforderlich. Die nach außen ragenden Spannbereiche verursachen dabei eine recht große Distanz zwischen Wendel und äußerem Abgasmantel, die den Gesamtdurchmesser des Heizgerätes vergrößert, was der angestrebten Kompaktheit widerspricht.The boards are relatively expensive, since at least for the respective inner corrosion reasons a high quality stainless steel must be used. In addition, the material waste is quite high, since the approximately round boards are punched out of square pre-material. In the two burner-side cover elements is still the waste for the burner opening added. Finally, when welding for clamping the burner-side double board a fairly large clamping area is required. The outwardly projecting clamping areas cause a fairly large distance between coil and outer exhaust jacket, which increases the overall diameter of the heater, which contradicts the desired compactness.

Der Erfindung liegt die Aufgabe zugrunde, die genannten Nachteile des Heizgerätes der eingangs genannten Art auf möglichst einfache Weise zu beseitigen, und zwar insbesondere unter dem Aspekt, dabei die Montage zu erleichtern und das Heizgerät noch kompakter und kostengünstiger auszubilden.The invention has for its object to eliminate the aforementioned disadvantages of the heater of the type mentioned in the simplest possible way, in particular from the aspect to facilitate assembly and even more compact and cost-effective form the heater.

Diese Aufgabe ist mit einem Heizgerät der eingangs genannten Art durch die im Kennzeichen des Anspruchs 1 aufgeführten Merkmale gelöst.This object is achieved with a heater of the type mentioned by the features listed in the characterizing part of claim 1.

Mit anderen Worten wird also vorgeschlagen, an den Wendelenden des Wärmetauschers jeweils stirnseitig einen rohrförmig ausgebildeten Anschlußstutzen anzuschweißen. Diese zwischenbaugruppe stellt dann den kompletten hydraulischen Druckkörper dar. Auf die axialen Stirnseiten des Wärmetauschers werden die Platinen, die vorzugsweise aus Aluminumdruckguss hergestellt sind, aufgeschoben, wobei auch hier die Platinenoberfläche vorzugsweise an die Wendelsteigung angepasst ausgebildet ist, um einen Abgasstrom zwischen Wendel und Platine zu verhindern. Vorzugsweise über ein Dichtelement (zum Beispiel O-Ring) erfolgt die abgasseitige Abdichtung zwischen den Anschlussstutzen und den Deckelelementen. Ein weiteres Dichtelement ist ferner vorzugsweise jeweils zwischen der Platine und dem äußeren Abgasmantel (Mantelteil) vorgesehen. Das Mantelteil besteht aus einem annähernd zylindrischen Mantel, dessen Stirnseiten nach dem Einsetzen des Wärmetauschers und der Platinen vorzugsweise nach innen gebördelt werden, so dass diese Bauteile fixiert sind. Am Abgasmantel ist vorzugsweise eine obere Öffnung für den Abgasaustritt und eine untere für den Kondensatablauf vorgesehen. An der Frontplatine sind darüber hinaus vorzugsweise die Haltepunkte für den Brenner sowie die Schnittstelle zur Brennerdichtung intergriert. Schließlich sind an der Rückplatine die Aufhängepunkte für das gesamte Heizgerät sowie ein sogenannter Befestigungsdom für eine Brennraumdämmung angeordnet.In other words, it is therefore proposed to weld at the helical ends of the heat exchanger in each case the end face of a tubular connecting piece. This intermediate assembly then represents the complete hydraulic pressure body. On the axial end faces of the heat exchanger, the boards, which are preferably made of aluminum die-cast pushed, where also the board surface is preferably formed adapted to the helical pitch, to prevent an exhaust gas flow between the coil and the circuit board. Preferably, via a sealing element (for example, O-ring), the exhaust gas-side seal between the connecting piece and the cover elements takes place. A further sealing element is furthermore preferably provided in each case between the circuit board and the outer exhaust jacket (jacket part). The shell part consists of an approximately cylindrical shell whose end faces are preferably crimped inwardly after insertion of the heat exchanger and the boards, so that these components are fixed. The exhaust jacket is preferably provided an upper opening for the exhaust gas outlet and a lower for the condensate drain. In addition, preferably the breakpoints for the burner and the interface to the burner seal are integrated on the front panel. Finally, the suspension points for the entire heater and a so-called Befestigungsdom for a combustion chamber insulation are arranged on the backplane.

Andere vorteilhafte Weiterbildungen ergeben sich aus den abhängigen Ansprüchen.Other advantageous developments emerge from the dependent claims.

Das erfindungsgemäße Heizgerät einschließlich seiner vorteilhaften Weiterbildungen gemäß der abhängigen Ansprüche wird nachfolgend anhand der zeichnerischen Darstellung verschiedener Ausführungsbeispiele näher erläutert.The heater according to the invention, including its advantageous developments according to the dependent claims will be explained in more detail with reference to the drawings of various embodiments.

In Figur 7 ist zunächst ein nach dem Stand der Technik bekanntes Heizgerät dargestellt (siehe hierzu auch die jedenfalls ähnliche DE 101 14 490 C1 ). Dieses Heizgerät umfasst - wie auch das erfindungsgemäße - einen schraubenförmig gewendelten, aus Korrosionsgründen aus Edelstahl gebildeten Wärmetauscher 1, der kühlwasserseitig einen etwa rechteckigen Durchströmungsquerschnitt aufweist und bei dem zwischen den sich ergebenden Wendeln des Wärmetauschers 1 Abgasströmungsspalte 25 vorgesehen sind. Ferner ist eine zylindrische Brennkammer 2 vorgesehen, die axial von einem vorderen 3 und einem hinteren Deckelelement 4 und radial vom Wärmetauscher 1 begrenzt ist, wobei ein Brenner 5 für flüssige oder gasförmige Brennstoffe an einem der beiden Deckelelemente 3, 4 (hier Deckelelement 3) angeordnet ist. Darüber hinaus weist sowohl das erfindungsgemäße Heizgerät (siehe Figuren 1 bis 6 und 8 und 9) als auch das Gerät gemäß Figur 7 ein Gehäuse 6 auf, das aus einem Mantelteil 7 und den Deckelelementen 3, 4 gebildet ist und den Wärmetauscher 1 unter Ausbildung eines Abgaskanals 8 umschließt.In FIG. 7, a heater known from the prior art is first of all shown (see also the similar ones in any case) DE 101 14 490 C1 ). This heater comprises - as well as the inventive - a helically coiled, formed from stainless steel corrosion reasons heat exchanger 1, the cooling water side has an approximately rectangular flow cross-section and in which between the resulting coils of the heat exchanger 1 exhaust gas flow column 25 are provided. Further, a cylindrical combustion chamber 2 is provided, which is axially bounded by a front 3 and a rear cover member 4 and radially from the heat exchanger 1, wherein a burner 5 for liquid or gaseous fuels on one of the two cover elements 3, 4 (here cover element 3) is. In addition, both the heater according to the invention (see Figures 1 to 6 and 8 and 9) and the device according to Figure 7, a housing 6, which is formed from a shell part 7 and the cover elements 3, 4 and the heat exchanger 1 to form a Exhaust gas channel 8 encloses.

Wesentlich für das erfindungsgemäße Heizgerät ist nun, dass der Wärmetauscher 1 an seinen beiden Enden 9, 10 axial orientiert ausgerichtete Anschlußstutzen 11, 12 aufweist und dass an den Deckelelementen 3, 4 an die Anschlußstutzen 11, 12 formangepaßt ausgebildete und von diesen abgedichtet durchgriffene Öffnungen 13, 14 vorgesehen sind, wobei die Deckelelemente 3, 4 vorzugsweise axial in das Mantelteil 7 einschieb- und formschlüssig mit diesem abgedichtet verbindbar ausgebildet sind.Essential for the heater according to the invention is now that the heat exchanger 1 at its two ends 9, 10 axially oriented aligned connecting pieces 11, 12 and that on the cover elements 3, 4 formed on the connecting pieces 11, 12 form-fitting and sealed by these openings durchgriffene openings , 14 are provided, wherein the cover elements 3, 4 are preferably axially inserted into the shell part 7 and positively formed with this sealed connectable.

Wie insbesondere aus Figur 5 und 6 ersichtlich, wird der Wärmetauscher 1 also zunächst als Wendel hergestellt. An seinen beiden Enden 9, 10 werden vorzugsweise etwa kreisrunde Löcher eingebracht und der offene, rechteckige Durchströmungsquerschnitt wird, wie in Figur 6 dargestellt, mit einem Deckelelement verschlossen. In die kreisrunden Löcher werden die erwähnten, rohrförmig ausgebildeten und wie der Wärmetauscher 1 ebenfalls aus Edelstahl gebildeten Anschlußstutzen 11, 12 eingesetzt und angeschweißt.As can be seen in particular from FIGS. 5 and 6, the heat exchanger 1 is therefore initially produced as a helix. At his Both ends 9, 10 are preferably introduced approximately circular holes and the open, rectangular flow cross-section, as shown in Figure 6, sealed with a cover member. In the circular holes mentioned, tubular and formed as the heat exchanger 1 also made of stainless steel connecting pieces 11, 12 are used and welded.

Dieser als vollständiger hydraulischer Druckkörper ausgebildete Wärmetauscher 1 wird dann in einem nächsten Montageschritt unter Ausbildung des oben erwähnten Abgaskanals 8 in den Mantelteil 7 eingeschoben. Zur Fixierung des Wärmetauschers 1 werden ferner front- und rückseitig die oben bereits erwähnten Deckelelemente 3, 4 mit in das Mantelteil 7 miteingeschoben, wobei sowohl das Mantelteil 7 als auch die Deckelelemente 3, 4 vorzugsweise einen kreisförmigen Querschnitt aufweisen.This designed as a complete hydraulic pressure body heat exchanger 1 is then inserted in a next assembly step to form the above-mentioned exhaust passage 8 in the shell part 7. For fixing the heat exchanger 1, the cover elements 3, 4 already mentioned above are also pushed along in the front and rear side into the jacket part 7, wherein both the jacket part 7 and the cover elements 3, 4 preferably have a circular cross section.

Um einen gasdichten Abschluss der Deckelelemente 3, 4 zum Mantelteil 7 zu gewährleisten, ist vorteilhaft vorgesehen, dass zwischen diesen beiden Bauteilen eine Dichtung 16 - für einen besonders guten Toleranzausgleich vorzugsweise wie angedeutet dargestellt eine Lippen- bzw. Doppellippen-Dichtung - angeordnet ist. Darüber hinaus weist das Mantelteil 7 bei metallischer Ausführung beidseitig umlaufende Kanten 21 auf, die - wie aus den Figuren 1, 3 und 4 ersichtlich, nach Montage der Deckelelemente 3, 4 umgebördelt werden.In order to ensure a gas-tight closure of the cover elements 3, 4 to the shell part 7, it is advantageously provided that between these two components a seal 16 - for a particularly good tolerance compensation preferably as indicated a lip or double lip seal - is arranged. In addition, the shell part 7 at metallic version on both sides encircling edges 21, which - as shown in Figures 1, 3 and 4, after assembly of the cover elements 3, 4 are crimped.

Die vorzugsweise kreisförmig ausgebildeten Öffnungen 13, 14 an den Deckelelementen 3, 4 weisen ferner einen Durchmesser DO auf, der geringfügig größer als der Aussendurchmesser (DA) der rohrförmig ausgebildeten Anschlußstutzen (11, 12) ausgebildet ist, wobei darüber hinaus vorzugsweise zwischen den Anschlußstutzen 11, 12 und den Deckelelementen 3, 4 jeweils eine Dichtung 15, vorzugsweise eine O-Ring-Dichtung, vorgesehen ist.The preferably circular openings 13, 14 on the cover elements 3, 4 further have a diameter D O , which is slightly larger than the outer diameter (D A ) of the tubular connecting piece (11, 12) is formed, moreover, preferably between the Connection piece 11, 12 and the cover elements 3, 4 each have a seal 15, preferably an O-ring seal, is provided.

Als besonders vorteilhaft hat es sich herausgestellt, mindestens eines der beiden (vorzugsweise beide) Deckelelemente 3, 4 gusstechnisch herzustellen bzw. insbesondere aus Aluminiumdruckguss zu bilden. Diese Herstellungsweise ermöglicht vorallem auf einfache Weise die weitere, bevorzugte Maßgabe, die Deckelelemente 3, 4 wärmetauscherseitig jeweils mit einer an die Wendelsteigung angepaßten Oberflächenform zu versehen, so dass nicht ungewollt Abgas durch den Übergangsbereich zwischen Wärmetauscher 1 und Deckelelement 3, 4 strömt.It has proven to be particularly advantageous to produce at least one of the two (preferably both) cover elements 3, 4 by casting or, in particular, to form aluminum die-cast. This method of production makes possible above all In a simple way, the further, preferred proviso, the cover elements 3, 4 each heat exchanger side to be provided with a matched to the spiral pitch surface shape, so that not accidentally exhaust gas flows through the transition region between the heat exchanger 1 and cover element 3, 4.

Die aufgrund der guten Wärmeübertragung niedrigen Abgastemperaturen eröffnen ferner die insbesondere fertigungstechnisch günstige Möglichkeit, das Mantelteil 7 aus Kunststoff herzustellen. Insbesondere in diesem Fall ist dabei vorteilhaft vorgesehen, dass die Deckelelemente 3, 4, wie in Figur 8 und 9 dargestellt, über zuganker 26 fest, aber lösbar miteinander verbunden sind, wobei vorzugsweise mindestens drei, vorzugsweise vier Zuganker 26 vorgesehen sind, die außen am Gehäuse 6, das Mantelteil 7 umschließend angeordnet sind.The low exhaust gas temperatures due to the good heat transfer also open up the particularly favorable production possibility, the jacket part 7 to be made of plastic. In particular, in this case, it is advantageously provided that the cover elements 3, 4, as shown in Figure 8 and 9, via zuganker 26 firmly, but releasably connected to each other, preferably at least three, preferably four tie rods 26 are provided, the outside of Housing 6, the shell part 7 are arranged enclosing.

Unabhängig vom verwendeten Material ist ferner vorteilhaft vorgesehen, dass am Mantelteil 7 ein mit dem Abgaskanal 8 in Verbindung stehender Abgasaustritt 17 angeordnet ist. An diesen Abgasaustritt 17 schließt sich, was in Figur 9 dargestellt ist, ein Abgasrohr an, das vorzugsweise ebenfalls aus Kunststoff bestehen kann. Das Abgas selbst ist im Abgaskanal 8 bereits auf unter 100 °C abgekühlt und somit für einen Kunststoffmantel nicht mehr zu heiß.Regardless of the material used, it is furthermore advantageously provided that an exhaust gas outlet 17 communicating with the exhaust gas duct 8 is arranged on the casing part 7. At this exhaust gas outlet 17 closes, as shown in Figure 9, an exhaust pipe, which may preferably also consist of plastic. The exhaust gas itself is already cooled in the exhaust duct 8 to below 100 ° C and thus no longer too hot for a plastic jacket.

Wie beim Heizgerät gemäß Figur 7 weist auch der Mantelteil 7 des erfindungsgemäßen Heizgerätes an der geodätisch tiefsten Stelle einen Kondensatablauf 18 auf.
