Description

Die Erfindung bezieht sich auf einen Heizungswärmetauscher.The invention relates to a heating heat exchanger.

Bei derartigen Heizungswärmetauschern, die beispielsweise aus EP 1561075 B1 bekannt sind, wird Strahlungswärme und thermische Energie der Abgase eines zentrisch angeordneten, brennstoffbetriebenen Brenners auf einen diesen umgebenden, metallischen, wendelförmigen Wärmetauscher übertragen. Die Abgase werden in einem Gehäuse, welches den wendelförmigen Wärmetauscher umgibt, nach dem Wärmeaustausch gesammelt und dann über eine Abgasleitung abgeführt. Da die Abgase unter den Taupunkt abgekühlt werden, kann Kunststoff für das Gehäuse verwendet werden. Der wendelförmige, metallische Wärmetauscher wird mit Flanschen des Kunststoffgehäuses verbunden; an diese Flansche wiederum werden Kupferleitungen angeschlossen. Diese Kupferleitungen führen zu den Geräteanschlüssen, welche mit dem Heizungskreislauf verbunden werden und nehmen ferner die Umwälzpumpe auf. Gemäß dem Stand der Technik werden die Temperatursensoren zur Erfassung der Vorlauf- und Rücklauftemperatur an die Kupferleitungen angeklipst; die gute Wärmeleitung von Kupfer ermöglicht eine schnelle und exakte Erfassung der Vor- und Rücklauftemperatur.In such heating heat exchangers, for example EP 1561075 B1 are known, radiant heat and thermal energy of the exhaust gases of a centrally arranged, fuel-operated burner is transmitted to a surrounding metallic, helical heat exchanger. The exhaust gases are collected in a housing which surrounds the helical heat exchanger, after the heat exchange and then discharged via an exhaust pipe. Since the exhaust gases are cooled below the dew point, plastic can be used for the housing. The helical, metallic heat exchanger is connected to flanges of the plastic housing; In turn, copper pipes are connected to these flanges. These copper lines lead to the device connections, which are connected to the heating circuit and also take on the circulation pump. According to the prior art, the temperature sensors are clipped to the copper pipes for detecting the flow and return temperature; The good heat conduction of copper enables a fast and exact detection of the flow and return temperatures.

Aufgabe der Erfindung ist ein einfacherer Anschluss der Temperatursensoren an die Vorrichtung.The object of the invention is a simpler connection of the temperature sensors to the device.

Diese Aufgabe wird erfindungsgemäß dadurch gelöst, dass die Temperatursensoren nicht an die Kupferleitungen geklipst werden, sondern vielmehr in spezielle Sensoraufnahmen aufgenommen werden, welche eine direkte Berührung mit dem Wasserkreislauf ermöglichen.This object is achieved in that the temperature sensors are not clipped to the copper lines, but rather are included in special sensor recordings, which allow direct contact with the water cycle.

Vorteilhafte Ausgestaltungen ergeben sich aus den Merkmalen der abhängigen Ansprüche.Advantageous embodiments result from the features of the dependent claims.

Die Erfindung wird anhand der Figuren näher erläutert. Hierbei zeigen

  • Figur 1 einen Heizungswärmetauscher sowie
  • Figur 2 die erfindungsgemäßen Anschlussräume mit Temperatursensoranschlüssen für einen derartigen Heizungswärmetauscher.
The invention will be explained in more detail with reference to FIGS. Show here
  • FIG. 1 a heating heat exchanger as well
  • FIG. 2 the connection spaces according to the invention with temperature sensor connections for such a heat exchanger.

Figur 1 zeigt einen Heizungswärmetauscher 1 gemäß Stand der Technik, wie er detailliert in EP 1591075 B1 beschrieben ist. Ein metallischer Primärwärmeaustauscher 2 ist nahezu zentrisch in einem diesen umgebenden Gehäuse 3 aus Kunststoff angeordnet. Der Primärwärmeaustauscher 2 mündet mit seinen beiden Enden in zwei Anschlussräumen 4, 5; Details zur Befestigung und Abdichtung sind aus dem Stand der Technik bekannt. An den Anschlussräumen 4, 5 sind ferner Wasserleitungsanschlüsse 6, 7 zur Aufnahme von Leitungen eines üblichen Heizungskreislaufs angeordnet. Das Gehäuse 3 verfügt ferner über einen Abgasrohranschluss 9 zur Abführung der Verbrennungsabgase eines zentrisch innerhalb des Primärwärmetauschers 2 angeordneten Brenners. FIG. 1 shows a heating heat exchanger 1 according to the prior art, as described in detail in EP 1591075 B1 is described. A metallic primary heat exchanger 2 is arranged almost centrally in a surrounding plastic housing 3. The primary heat exchanger 2 opens with its two ends in two connection spaces 4, 5; Details for attachment and sealing are known from the prior art. At the connection spaces 4, 5 further water line connections 6, 7 are arranged for receiving lines of a conventional heating circuit. The housing 3 further has an exhaust pipe connection 9 for discharging the combustion exhaust gases of a burner arranged centrally within the primary heat exchanger 2.

Figur 2 zeigt am Gehäuse 3 einen Anschlussraum 4, in dem einerseits der metallische Primärwärmeaustauscher 2 endet. Zudem ist ein Heizungsrohr 10 über eine Flachdichtung 11 mit dem Anschlussraum 4 verbunden und über einen ersten Sicherungsring 12 gesichert. FIG. 2 shows on the housing 3 a connection space 4, in which on the one hand, the metallic primary heat exchanger 2 ends. In addition, a heating pipe 10 is connected via a flat gasket 11 to the connection space 4 and secured by a first securing ring 12.

Der Anschlussraum 4 verfügt des Weiteren über einen Temperatursensorenanschluss 8 mit einer Öffnung, durch welche ein Temperatursensor 13 in den Anschlussraum 4 ragt. Eine Radialdichtung 14 dichtet die Verbindung zwischen Anschlussraum 4 und Umgebung radial um den Temperatursensor 13 ab. Am Temperatursensor 13 ist ein Fixierring radial angeordnet, der eine Fixierung mittels eines zweiten Sicherungsrings 16 ermöglicht.The connection space 4 furthermore has a temperature sensor connection 8 with an opening through which a temperature sensor 13 projects into the connection space 4. A radial seal 14 seals the connection between connection space 4 and surroundings radially around the temperature sensor 13. At the temperature sensor 13, a fixing ring is arranged radially, which allows a fixation by means of a second locking ring 16.

Hierdurch ragt der Temperatursensor 13 direkt in den Wasserraum, so dass die Temperatur am Ein- und Auslauf des Primärwärmeaustauschers 2 mit einer - gegenüber der Messung mittels Sensorclip am Kupferrohr - schnelleren Reaktionszeit erfasst werden kann.In this way, the temperature sensor 13 projects directly into the water space, so that the temperature at the inlet and outlet of the primary heat exchanger 2 with a - compared to the measurement by means of sensor clip on copper pipe - faster reaction time can be detected.
