Description

Die Erfindung betrifft ein Heizgerät gemäß dem Oberbegriff des Patentanspruchs 1.The invention relates to a heater according to the preamble of patent claim 1.

Ein Heizgerät der eingangs genannten Art ist nach der EP 1 562 006 A1 bekannt. Dieses besteht aus einem schraubenförmig gewendelten, einen etwa rechteckigen Durchströmquerschnitt aufweisenden Wärmetauscher, einer Brennkammer, in der ein Brenner für flüssige oder gasförmige Brennstoffe angeordnet und die axial von mindestens einem Deckelelement und radial vom Wärmetauscher begrenzt ist, einem Gehäuse, das aus einem Mantelteil und dem mindestens einen Deckelelement gebildet ist und das den Wärmetauscher unter Ausbildung eines Abgaskanals umschließt, wobei der Wärmetauscher an seinem deckelelementzugewandten Ende einen axial orientiert ausgerichteten, rohrförmig ausgebildeten Anschlussstutzen zur Zu- oder Abführung eines Wärmeträgermediums (Heizkreiswasser) aufweist, wobei am Deckelelement eine formangepasst ausgebildete Öffnung vorgesehen ist, in die der Anschlussstutzen einsteckbar ausgebildet ist.A heater of the type mentioned is according to the EP 1 562 006 A1 known. This consists of a helically coiled, an approximately rectangular flow area having heat exchanger, a combustion chamber in which a burner for liquid or gaseous fuels arranged and which is axially bounded by at least one lid member and radially from the heat exchanger, a housing consisting of a shell part and the at least one cover element is formed and which encloses the heat exchanger to form an exhaust passage, wherein the heat exchanger at its cover element facing the end an axially oriented aligned, tubular connecting piece for supplying or discharging a heat transfer medium (Heizkreiswasser), wherein the cover member provided a shape adapted opening is, in which the connecting piece is formed plugged.

Typischerweise weist die beschriebene Lösung zwei Deckelelemente auf. Genausogut ist aber auch eine topfartige Mantelteilkonstruktion denkbar, die nur mit einem Deckelelement verschlossen wird. Darüber hinaus kann das Heizgerät auch mehr als einen Wendelrohrwärmetauscher aufweisen: dieserhalb wird auf die WO 2007/087801 A1 (siehe insbesondere Figur 6) verwiesen, die eine Doppelwendel mit einem gemeinsamen Anschlussstutzen zeigt.Typically, the described solution has two cover elements. But just as well, a cup-shaped shell part construction is conceivable, which is closed only with a cover element. In addition, the heater may also have more than one helical tube heat exchanger: thishalb is on the WO 2007/087801 A1 (see in particular FIG. 6 ), which shows a double helix with a common connecting piece.

Der Erfindung liegt die Aufgabe zugrunde, ein Heizgerät der eingangs genannten Art weiter zu verbessern.The invention has for its object to further improve a heater of the type mentioned.

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

Nach der Erfindung ist also vorgesehen, dass das Deckelelement einen Hohlraum zur Aufnahme des Wärmeträgermediums aufweist, in den der Anschlussstutzen ausmündend ausgebildet ist.According to the invention, it is thus provided that the cover element has a cavity for receiving the heat transfer medium, in which the connecting piece is formed ausmündend.

Mit anderen Worten mündet bei der erfindungsgemäßen Lösung der Anschlussstutzen nicht direkt in ein Rohr des Heizkreises, sondern in einen als Sammelraum ausgebildeten Hohlraum. Das Wärmeträgermedium strömt also wahlweise vom Hohlraum in den Wärmetauscher oder vom Wärmetauscher in den Hohlraum, wobei am Hohlraum selbst - zur Vermeidung eines hydraulischen Kurzschlusses - vorzugsweise distanziert zum Anschlussstutzen wahlweise der Vor- oder Rücklaufanschluss des Heizkreises angeschlossen ist. Im Unterschied zum vorbekannten Stand der Technik wird das Wärmeträgermedium also durch den Hohlraum geleitet, was in Konsequenz in überraschend einfacher Weise zu einem wassergekühlten Deckelelement führt.In other words, in the solution according to the invention, the connection pipe does not open directly into a pipe of the heating circuit, but rather into a cavity designed as a collecting space. The heat transfer medium thus flows either from the cavity in the heat exchanger or from the heat exchanger into the cavity, wherein the cavity itself - to avoid a hydraulic short circuit - preferably distanced to the connecting piece either the supply or return connection of the heating circuit is connected. In contrast to the prior art, the heat transfer medium is thus passed through the cavity, which leads in consequence in a surprisingly simple manner to a water-cooled cover element.

Als besonders vorteilhaft erweist sich die erfindungsgemäße Lösung dann, wenn, was unten noch genauer beschrieben wird, mehrere Wendelrohrwärmetauscher vorgesehen sind, und zwar insbesondere dann, wenn jeder Wendelrohrwärmetauscher deckelelementseitig einen eigenen Anschlussstutzen aufweist und diese über eine der Zahl der Wärmetauscher entsprechende Anzahl von Öffnungen in den erfindungsgemäßen Hohlraum ausmünden, was dann vorteilhaft dazu führt, dass das Wärmeträgermedium vor dem Eintritt in die Wärmetauscher bzw. in den Heizkreisvorlauf gleichmäßig vermischt wird bzw. ist.The solution according to the invention proves to be particularly advantageous if, as will be described in more detail below, a plurality of helical tube heat exchangers are provided, in particular if each helical tube heat exchanger has its own connecting piece on the cover element side and this has a number of openings corresponding to the number of heat exchangers open out the cavity according to the invention, which then advantageously leads to the fact that the heat transfer medium is uniformly mixed before entering the heat exchanger or in the heating circuit flow.

Andere vorteilhaft Weiterbildungen des erfindungsgemäßen Heizgerätes ergeben sich aus den abhängigen Patentansprüchen.Other advantageous developments of the heater according to the invention will become apparent from the dependent claims.

Das erfindungsgemäße Heizgerät einschließlich seiner vorteilhaften Weiterbildungen gemäß der abhängigen Patentansprüche 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.

Das in den Figuren 1 bis 7 dargestellte Heizgerät besteht aus mindestens einem (Figur 1 und 5 zeigen einen, Figur 6 und 7 zeigen drei) schraubenförmig gewendelten, einen etwa rechteckigen Durchströmquerschnitt aufweisenden Wärmetauscher 1, einer zylindrisch ausgebildeten Brennkammer 2, in der ein Brenner 3 für flüssige oder gasförmige Brennstoffe (Gas- oder Ölbrenner) angeordnet und die axial von mindestens einem Deckelelement 4 und radial vom Wärmetauscher 1 begrenzt ist, einem Gehäuse 5, das aus einem zylindrisch ausgebildeten Mantelteil 6 und dem mindestens einen Deckelelement 4 gebildet ist und das den Wärmetauscher 1 unter Ausbildung eines Abgaskanals 7 umschließt. Dabei weist der Wärmetauscher 1 an seinem deckelelementzugewandten Ende 8 einen axial orientiert (parallel zur Wärmetauscherwendelachse) ausgerichteten, rohrförmig ausgebildeten Anschlussstutzen 9 zur Zu- oder Abführung eines Wärmeträgermediums auf, wobei am Deckelelement 4 eine formangepasst ausgebildete Öffnung 10 vorgesehen ist, in die der Anschlussstutzen 9 einsteckbar ausgebildet ist. Dabei weisen sowohl der Anschlussstutzen 9 als auch die Öffnung 10 einen kreisförmigen Querschnitt auf, wobei zwischen dem Anschlussstutzen 9 und der Öffnung 10 ein Dichtelement 20, vorzugsweise ein O-Ring, angeordnet ist.That in the FIGS. 1 to 7 shown heater consists of at least one ( FIG. 1 and 5 show one, FIGS. 6 and 7 show three) helically coiled, an approximately rectangular flow area having heat exchanger 1, a cylindrically shaped combustion chamber 2, in which a burner 3 for liquid or gaseous fuels (gas or oil burner) arranged and the axially of at least one cover element 4 and radially from the heat exchanger. 1 is limited, a housing 5, which is formed of a cylindrical shell part 6 and the at least one cover member 4 and the heat exchanger 1 to form an exhaust passage 7 encloses. In this case, the heat exchanger 1 at its cover element facing the end 8 an axially oriented (parallel to the heat exchanger coil axis) aligned, tubular connecting piece 9 for supply or discharge of a heat transfer medium, wherein the lid member 4 is a form-fitting opening 10 is provided, into which the connecting piece is designed plugged. Both the connecting piece 9 and the opening 10 have a circular cross section, wherein between the connecting piece 9 and the opening 10, a sealing element 20, preferably an O-ring, is arranged.

Wesentlich für alle Ausführungsformen des erfindungsgemäßen Heizgerätes ist nun, dass das Deckelelement 4 einen Hohlraum 11 zur Aufnahme des Wärmeträgermediums aufweist, in den der Anschlussstutzen 9 ausmündend ausgebildet ist. Bei den Figuren 1, 6 und 7 sind jeweils an beiden Gehäuseenden bzw. beiden Enden der Brennkammer 2 Deckelelemente 4 mit jeweils einem Hohlraum 11 vorgesehen. Bei der Lösung gemäß Figur 5 ist nur am rechten Deckelelement 4 der erfindungsgemäße Hohlraum 11 vorgesehen. Die Kombination aus Hohlraum 11 und einsteckbarem Anschlussstutzen 9 führt, wie eingangs erläutert, zu einer leicht montierbaren Konstruktion, die darüber hinaus den Vorteil hat, dass die Deckelelemente 4 direkt wassergekühlt sind.Essential for all embodiments of the heater according to the invention is now that the cover member 4 has a cavity 11 for receiving the heat transfer medium, in which the connecting piece 9 is formed ausmündend. Both FIGS. 1 . 6 and 7 are each provided at both housing ends or both ends of the combustion chamber 2 cover elements 4, each having a cavity 11. In the solution according to FIG. 5 is provided only on the right cover element 4 of the cavity 11 according to the invention. The combination of cavity 11 and plug-in connection piece 9 leads, as explained above, to an easily assembled construction, which moreover has the advantage that the cover elements 4 are directly water-cooled.

Insbesondere mit Verweis auf Figur 3 und 4 ist bezüglich dieser Wasserkühlung bevorzugt vorgesehen, dass im Hohlraum 11 mindestens eine Strömungsführung 12 angeordnet ist.In particular with reference to FIGS. 3 and 4 is preferably provided with respect to this water cooling, that in the cavity 11 at least one flow guide 12 is arranged.

In Figur 3 ist diese in Form von Leittrennwänden ausgebildet, wobei der Rücklaufanschluss eines Heizkreises für die Zuführung von Wärmeträgermedium zum Hohlraum 11 an die Anschlussöffnung 17 angeschlossen ist (nicht extra dargestellt, da ohne weiteres vorstellbar). Das Wärmeträgermedium (Heizkreiswasser) durchströmt nach Eintritt in die Anschlussöffnung 17 und geführt von den Strömungsführungen 12 das Deckelelement 4, bis es zur Öffnung 10 (nur angedeutet dargestellt) und von dort über den Anschlussstutzen 9 in den Wärmetauscher 1 gelangt. Um dabei in das Deckelelement 4 eintretende Luft noch vor dem Eintritt in den Wärmetauscher 1 sicher abführen zu können, ist am oberen Ende des Deckelelements 4 ein mit dem Hohlraum 11 direkt in Verbindung stehender Entlüftungsanschluss 13 vorgesehen.In FIG. 3 this is designed in the form of Leittrennwänden, the return port of a heating circuit for the supply of heat transfer medium to the cavity 11 is connected to the connection port 17 (not shown separately, as readily imaginable). The heat transfer medium (heating circuit water) flows through after entry into the connection opening 17 and guided from the flow guides 12, the cover member 4 until it reaches the opening 10 (shown only indicated) and from there via the connecting piece 9 in the heat exchanger 1. In order to be able to safely discharge air entering the cover element 4 even before it enters the heat exchanger 1, a venting connection 13 directly communicating with the cavity 11 is provided at the upper end of the cover element 4.

In Figur 4, die ein Deckelelement 4 zeigt, das zur Aufnahme des Brenners 3 mit einer Aufnahmeöffnung 19 versehen ist, strömt das Wärmeträgermedium von der Öffnung 10 in den Hohlraum 11. Dort ist als Strömungsführung 12 ein kreisringförmiger Kanal gebildet, der das Wärmeträgermedium dann zur Anschlussöffnung 17 führt.In FIG. 4 , which shows a lid member 4, which is provided for receiving the burner 3 with a receiving opening 19, the heat transfer medium from the opening 10 into the cavity 11 flows. There, an annular channel is formed as a flow guide 12, which then leads the heat transfer medium to the connection opening 17 ,

Während also das Deckelelement 4 gemäß Figur 3 an den Rücklauf eines Heizkreises angeschlossen ist, ist das Deckelelement 4 gemäß Figur 4 an den Vorlauf des Heizkreises angeschlossen.Thus, while the lid member 4 according to FIG. 3 is connected to the return of a heating circuit, the cover element 4 is according to FIG. 4 connected to the flow of the heating circuit.

Eine weitere Besonderheit des erfindungsgemäßen Deckelelements 4 besteht gemäß Figur 1 bis 4 darin, dass dieses aus zwei, den Hohlraum 11 umschließenden Schalen 14, 15 gebildet ist, wobei eine erste Schale 14 (Außenschale) eine äußere Oberfläche des Gehäuses 5 und eine zweite Schale 15 (Innenschale) eine innere Oberfläche in der Brennkammer 2 bildet. Weiterhin ist die besagte Strömungsführung 12 jeweils an einer solchen Schale 14, 15 ausgebildet, wobei ferner die Schalen 14, 15 kreisscheibenförmig ausgebildet sind und wobei zwischen den Schalen 14, 15 ein Dichtelement 16 (nur angedeutet dargestellt) angeordnet ist.Another special feature of the cover element 4 according to the invention is according to Figure 1 to 4 in that it is formed from two shells 14, 15 enclosing the cavity 11, wherein a first shell 14 (outer shell) forms an outer surface of the housing 5 and a second shell 15 (inner shell) forms an inner surface in the combustion chamber 2. Furthermore, the said flow guide 12 is formed in each case on such a shell 14, 15, wherein further the shells 14, 15 are formed circular disc-shaped and between the shells 14, 15, a sealing element 16 (only indicated) is arranged.

Die Schalen 14, 15 gemäß den Figuren 1 bis 4 sind gusstechnisch hergestellt und bestehen vorzugsweise aus einem Aluminiumguss. Die Deckelelemente 4 gemäß den Figuren 5 und 6 sind auch gegossen, allerdings im so genannten Kerngussverfahren, d. h. diese Deckelelemente 4 sind einteilig ausgebildet, wobei der Hohlraum 11 durch einen entsprechenden verlorenen Kern beim Gießen erzeugt wird.The shells 14, 15 according to the FIGS. 1 to 4 are produced by casting and preferably consist of a cast aluminum. The cover elements 4 according to the Figures 5 and 6 are also cast, but in the so-called core casting process, ie these cover elements 4 are integrally formed, wherein the cavity 11 is generated by a corresponding lost core during casting.

Da sich an den Enden des Wärmetauschers 1 aufgrund der Steigung der Wendel ein Absatz ergibt, ist insbesondere unter Ausnutzung der Gusstechnik vorteilhaft vorgesehen, dass das Deckelelement 4 brennkammerseitig an den gewendelten Wärmetauscher 1 formangepasst ausgebildet ist. Dies ist gut an den Absätzen 18 in den Figuren 2 und 4 erkennbar.Since there is a shoulder at the ends of the heat exchanger 1 due to the pitch of the helix, it is advantageously provided, in particular by utilizing the casting technique, that the cover element 4 is formed in shape matching the combustion chamber side to the coiled heat exchanger 1. This is good at paragraphs 18 in the Figures 2 and 4 recognizable.

Weiterhin vorteilhaft ist vorgesehen (siehe insbesondere Figur 1, 5 und 6), dass das Deckelelement 4 in den Mantelteil 6 einschieb- und fixierbar, vorzugsweise durch Umbördeln, ausgebildet ist.Further advantageous is provided (see in particular FIG. 1 . 5 and 6 ), that the cover element 4 in the shell part 6 einschieb- and fixable, preferably by crimping, is formed.

Schließlich ist mit Verweis auf Figur 6 und 7 vorteilhaft vorgesehen, dass drei schraubenförmig gewendelte, ineinander gedrehte Wärmetauscher 1 zur Ausbildung eines besonders großen Heizgerätes eingesetzt werden. Das mit dem Hohlraum 11 versehene Deckelelement 4 bildet dabei, wie eingangs bereits erläutert, einen Sammler, in den entsprechend die drei Anschlussstutzen 9 der Wärmetauscher 1 um 120° versetzt ausmünden. Die Zu- oder Abfuhr des Wärmeträgermediums erfolgt über einen gemeinsamen Anschluss am Deckelelement 4, der in Figur 6 beim linken Deckelelement 4 mittig und beim rechten Deckelelement 4 oben angeordnet ist (die Pfeile verdeutlichen die Strömungsrichtung des Wärmeträgermediums).Finally, with reference to FIGS. 6 and 7 advantageously provided that three helically coiled, nested heat exchanger 1 are used to form a particularly large heater. The lid member 4 provided with the cavity 11 forms, as already explained, a collector into which the three connecting pieces 9 of the heat exchangers 1 are opened by 120 °. The supply or removal of the heat transfer medium via a common connection on the cover element 4, the in FIG. 6 the left lid member 4 is arranged centrally and the right lid member 4 above (the arrows illustrate the flow direction of the heat transfer medium).
