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 aus dem Patentdokument
Ein Heizgerät gemäß dem Oberbegriff des Patentanspruchs 1 ist aus dem Patentdokument
Der Erfindung liegt die Aufgabe zugrunde, ein Heizgerät der eingangs genannten Art zu verbessern. Insbesondere soll ein Heizgerät mit einer weiter verbesserten Wärmeübertragung im Bereich des Heizgaszuges vom Abgas auf das Heizkreiswaser geschaffen werden.The invention has for its object to improve a heater of the type mentioned. In particular, a heater is to be created with a further improved heat transfer in the field of Heizgaszuges from the exhaust gas to the Heizkreiswaser.
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 claim 1.
Nach der Erfindung ist also vorgesehen, dass auf Seiten des Eintrittsbereichs die Wandstärke der Wärmeübertragungsrippen größer bzw. die Wärmeübertragungsrippen dickwandiger als auf Seiten des Austrittsbereichs ausgebildet ist bzw. sind und dass eine zwischen dem Abgas und dem Wasser angeordnete Wandung des Heizgaszuges eine Wandstärke aufweist, die kleiner als die kleinste Wandstärke der Wärmeübertragungsrippe ausgebildet ist.According to the invention, it is thus provided that the wall thickness of the heat transfer ribs is greater or the heat transfer ribs are thick-walled on the side of the entry region than on the side of the exit region and if a wall of the heating gas duct arranged between the exhaust gas and the water has a wall thickness which smaller than the smallest wall thickness of the heat transfer rib is formed.
Mit anderen Worten zeichnet sich die erfindungsgemäße Lösung somit dadurch aus, dass am Heizgaszug bauliche Maßnahmen ergriffen werden, die einer sich zwischen dem Eintritts- und Austrittsbereich abkühlenden Abgasströmung Rechnung tragen. Auf Seiten des Eintrittsbereichs, also dort wo die Temperatur des Abgases noch vergleichsweise hoch ist, wird dabei eine dickwandigere Wärmeübertragungsrippe als am Austrittsbereich eingesetzt. Diese Maßnahme führt, was unten noch genauer erläutert wird, zu einem an die jeweilige Temperatur des sich im Heizgaszugverlauf abkühlenden Abgases optimal angepassten Heizgaszug.In other words, the solution according to the invention is thus distinguished by the fact that constructional measures are taken on the hot gas flue which take into account a flow of exhaust gas which cools between the inlet and outlet regions. On the side of the inlet region, ie where the temperature of the exhaust gas is still comparatively high, a thicker-walled heat transfer rib is used than at the exit region. This measure, which will be explained in more detail below, leads to a heating gas train optimally adapted to the respective temperature of the exhaust gas cooling down in the course of the heating gas flow.
Die bezüglich der Variation der Wandstärke auf der Hand liegende alternative Lösung, nämlich einfach seitens des Eintrittsbereichs ein temperaturbeständigeres Material als am Austrittsbereich vorzusehen, ist dabei für die Lösung der gestellten Aufgabe insofern nicht zielführend, als die Verarbeitung unterschiedlicher Materialien im Verlauf des Heizgaszuges aufwändig und absehbar mit Problemen wegen unterschiedlicher Wärmeausdehnungen der unterschiedlichen Materialien verbunden wäre.With respect to the variation of the wall thickness obvious alternative solution, namely simply provide a more temperature-resistant material than the exit area from the inlet area, is not effective for the solution of the problem insofar as the processing of different materials in the course of Heizgaszuges consuming and foreseeable with problems because of different Thermal expansions of different materials would be connected.
Andere vorteilhafte Weiterbildungen ergeben sich aus den abhängigen Patentansprüchen.Other advantageous developments emerge 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 dargestellte Heizgerät besteht in an sich bekannter Weise aus einer Brennkammer 1 und einem zur Führung von heißem, in der Brennkammer 1 mit einem nicht extra dargestellten Brenner erzeugtem Abgas ausgebildeten Heizgaszug 2, wobei dieser einen Eintrittsbereich 2.1 und einen Austrittsbereich 2.2 aufweist und mit der Brennkammer 1 über den Eintrittsbereich 2.1 verbunden ausgebildet ist und wobei im Heizgaszug 2 zur Wärmeübertragung vom heißen Abgas auf den Heizgaszug 2 zueinander beabstandete, eine Wandstärke aufweisende Wärmeübertragungsrippen 3 aus einem metallischen Material angeordnet sind.The heater shown in the figures consists in a conventional manner of a combustion chamber 1 and a trained to conduct hot, in the combustion chamber 1 with a not-shown burner
Wie beim eingangs genannten Stand der Technik ist auch beim erfindungsgemäßen Heizgerät, um eine ausreichende Abgasmenge aus der Brennkammer 1 abführen zu können, vorgesehen, dass die Brennkammer 1 mit mehreren (hier vier), parallel vom Abgas durchströmten Heizgaszügen 2 verbunden ausgebildet ist. Der Heizgaszug 2 selbst weist dabei eine (etwa) rechteckige Querschnittsfläche mit einer Länge und mit einer Breite auf, wobei die Länge einem Vielfachen der Breite entspricht.As in the prior art mentioned above, in the heater according to the invention, in order to be able to dissipate a sufficient amount of exhaust gas from the combustion chamber 1, it is provided that the combustion chamber 1 is connected to a plurality of (here four)
Außerdem ist in an sich bekannter Weise vorgesehen, dass der Heizgaszug 2 über den Austrittsbereich 2.2 mit einer Abgassammelkammer 4 verbunden ausgebildet ist. Dabei ist weiterhin die Brennkammer 1 oberhalb des Heizgaszuges 2 und dieser oberhalb der Abgassammelkammer 4 angeordnet. Die Abgassammelkammer 4 ist ihrerseits in bekannter Weise (und daher nicht extra dargestellt) mit einem Kamin eines Gebäudes oder dergleichen verbunden.In addition, it is provided in a conventional manner that the
Wesentlich für das erfindungsgemäße Heizgerät ist nun, dass auf Seiten des Eintrittsbereichs 2.1 die Wandstärke der Wärmeübertragungsrippen 3 größer bzw. die Wärmeübertragungsrippen 3 dickwandiger als auf Seiten des Austrittsbereichs 2.2 ausgebildet ist bzw. sind.Essential for the heater according to the invention is now that on the side of the inlet region 2.1, the wall thickness of the
Wie eingangs erläutert, führen diese Maßgaben zu einem Heizgerät, bei dem einerseits die Wärmeübertragungsrippen 3 im Eintrittsbereich 2.1 den noch hohen Temperaturen des Abgases gut standhalten können und bei dem andererseits mit Hilfe von dünnwandigen Wärmeübertragungsrippen 3 im Austrittsbereich 2.2 für eine besonders gute Wärmeübertragung gesorgt ist.As explained above, these provisos lead to a heater in which on the one hand the
In den Figuren ist dabei ein Heizgaszug 2 mit zwei verschiedenen Zonen dargestellt.
Wie ohne weiteres verständlich zeigen die
Wie der Vergleich der
Bezüglich der Dimensionierung der Bauteile des erfindungsgemäßen Heizgerätes, bei dem außerdem, wie oben bereits erwähnt, der Heizgaszug 2 einerseits vom Abgas durchströmt und andererseits von Wasser (insbesondere Heizkreiswasser) umgeben ausgebildet ist, ist ferner für eine besonders gute Wärmeübertragung erfindungsgemäß vorgesehen, dass eine zwischen dem Abgas und dem Wasser angeordnete Wandung des Heizgaszuges 2 eine Wandstärke aufweist, die kleiner als die kleinste Wandstärke der Wärmeübertragungsrippe 3 ausgebildet ist. Hierzu ist weiterhin bevorzugt vorgesehen, dass die Wandung des Heizgaszuges 2 aus einem metallischen Blechmaterial gebildet ist.With regard to the dimensioning of the components of the heater according to the invention, in which also, as already mentioned above, the
Noch etwas genauer betrachtet, ist bei dem erfindungsgemäßen Heizgerät, bei dem außerdem eine Wandung des Heizgaszuges 2 und die Wärmeübertragungsrippen 3 als separate Bauteile ausgebildet sind, besonders bevorzugt vorgesehen, dass die Wärmeübertragungsrippen 3 als Abstützung der Wandung des Heizgaszuges 2 gegen den von außen anstehenden Wasserdruck ausgebildet sind.Considered in more detail, in the heater according to the invention, in which also a wall of the
Im Unterschied zum vorgenannten Stand der Technik ist darüber hinaus zur weiteren Verbesserung der Wärmeübertragung im Heizgaszug 2 für einen direkten Kontakt des Abgases mit einer Wandung des Heizgaszuges 2 ein von den Wärmeübertragungsrippen 3 freigelassener Wandbereich 2.4 am Heizgaszug 2 vorgesehen. Es gibt somit im Heizgaszug 2 einerseits direkt mit den Wärmeübertragungsrippen 3 in Kontakt stehende und diese abstützende Wandbereiche 2.5 und andererseits entsprechend frei gelassende Wandbereiche 2.4. Dabei sind, wie die Figuren zeigen, die Wärmeübertragungsrippen 3 vorzugsweise in ein- (siehe insbesondere
Da das erfindungsgemäße Heizgerät zur Erzielung eines hohen Wirkungsgrades als so genanntes Brennwertgerät betrieben werden soll, ist ferner besonders bevorzugt vorgesehen, dass der Heizgaszug 2 und/oder die Wärmeübertragungsrippen 3 aus einem einem aus dem Abgas resultierenden Kondensat widerstehenden Material gebildet ist bzw. sind.Since the heater according to the invention is to be operated as a so-called condensing boiler to achieve high efficiency, it is also particularly preferred that the Heizgaszug 2 and / or the

Diese Maßgabe bringt den Vorteil mit sich, dass sich das heiße, insbesondere im Zentralbereich in den Heizgaszug einströmende Abgas zunächst etwas abkühlen kann, bevor es mit den Wärmeübertragungsrippe 3 in Kontakt kommt. Gleichzeitig ist aber durch die im weniger mit heißem Abgas beaufschlagten Randbereich etwas verlängerte Ausbildung der Wärmeübertragungsrippen 3 nach wie vor für eine ausreichende Abstützung der Wandung des Heizgaszuges 2 gesorgt.This proviso has the advantage that the hot, especially in the central region in the Heizgaszug inflowing First, the exhaust gas can cool down a little before it comes into contact with the
