Description
Die Erfindung bezieht sich auf ein Heizgerät mit hitzeempfindlichen Bauelementen gemäß dem Oberbegriff der unabhängigen Ansprüche.The invention relates to a heater with heat sensitive components according to the preamble of the independent claims.
Bei gasbetriebenen Heizgeräten wird ein Brenngas-Luft-Gemisch verbrannt, die heißen Verbrennungsabgase werden in einem Abgaswärmeaustauscher abgekühlt und anschließend durch eine Abgasleitung ins Freie geleitet. Häufig wird ein koaxiales Abgassystem verwendet, bei dem die Frischluftleitung konzentrisch um die Abgasleitung geführt wird. Ein Teil der im Abgas enthaltenen Wärme geht somit auf die Frischluft über die gemeinsame Wand des koaxialen Abgassystems über.In gas-powered heaters, a combustible gas-air mixture is burned Combustion gases are cooled in an exhaust gas heat exchanger and then passed outside through an exhaust pipe. Often a coaxial Exhaust system used in which the fresh air line concentric around the exhaust line to be led. Part of the heat contained in the exhaust gas is thus transferred to the fresh air common wall of the coaxial exhaust system over.
Heizgeräte verfügen häufig über eine geschlossene Kammer, die sogenannte Unterdruckkammer, in welche die Verbrennungsluft einströmt und welche die Brennkammer des Heizgerätes umströmt. Die Unterdruckkammer hat zwei Aufgaben: Einerseits können keine Abgase aus der Brennkammer in die Umgebung gelangen, da Leckströme in die Unterdruckkammer gelangen würden und dort mit der Frischluft über den Brenner gezielt in das Abgassystem geleitet würden. Andererseits nimmt die Frischluft Wärmeverluste der Brennkammer auf, so dass die Wärme im System bleibt.Heaters often have a closed chamber, the so-called Vacuum chamber into which the combustion air flows and which the combustion chamber flows around the heater. The vacuum chamber has two functions: On the one hand, it can no exhaust gases from the combustion chamber get into the environment, as leakage currents into the Vacuum chamber would enter and there with the fresh air through the burner the exhaust system would be directed. On the other hand, the fresh air takes heat losses from the Combustion chamber so that the heat stays in the system.
Manche Heizgeräten verfügen über eine abgasseitige Gebläseunterstützung. Bei diesen Geräten wird ein Brenngas-Luft-Gemisch in einer Brennkammer verbrannt, die heißen Verbrennungsabgase werden in einem Abgaswärmeaustauscher abgekühlt und anschließend von einem Abgasgebläse durch eine Abgasleitung ins Freie gedrückt. Das Abgasgebläse sorgt für einen Unterdruck im Heizgerät auf der Saugseite des Gebläses, wodurch Frischluft aus dem Freien in das Gerät strömt. Häufig werden koaxiale Abgassysteme verwendet, bei denen koaxial im Inneren eine Abgasleitung liegt und darum eine Frischluftleitung angeordnet ist. Ein Teil der im Abgas enthaltenen Wärme geht somit auf die Frischluft über die gemeinsame Wand des koaxialen Abgassystems über. Die Heizgeräte verfügen typischerweise über eine geschlossene Kammer, die sogenannte Unterdruckkammer, in welche die Verbrennungsluft einströmt und welche die Brennkammer des Heizgerätes umströmt.Some heaters have fan support on the exhaust gas side. With these Devices burn a mixture of gas and air in a combustion chamber called hot Combustion gases are cooled in an exhaust gas heat exchanger and then pushed into the open by an exhaust gas blower through an exhaust gas line. The Exhaust fan ensures a negative pressure in the heater on the suction side of the fan, whereby fresh air from outside flows into the device. Often they become coaxial Exhaust systems are used in which there is an exhaust pipe coaxially inside and therefore a fresh air line is arranged. Part of the heat contained in the exhaust gas is therefore lost to the fresh air through the common wall of the coaxial exhaust system. The Heaters typically have a closed chamber, the so-called Vacuum chamber into which the combustion air flows and which the combustion chamber flows around the heater.
Die Nutzung der Wärmeverluste durch das koaxiale Abgassystem und die Unterdruckkammer haben jedoch zur Folge, dass die Luft in der Unterdruckkammer stark erwärmt wird und somit manche Bauteile im Heizgerät nur ungenügend Abwärme abgeben können. Da in solchen Heizgeräten Temperaturen über 120°C auftreten können, sind Fehlfunktionen von hitzeempfindlichen Bauelementen nicht ausgeschlossen.The use of heat losses through the coaxial exhaust system and Vacuum chamber, however, have the consequence that the air in the vacuum chamber is strong is heated and therefore some components in the heater give off insufficient waste heat can. Since temperatures above 120 ° C can occur in such heaters, they are malfunctions not excluded from heat sensitive components.
Aufgabe der Erfindung ist es somit, ein Heizgerät mit Gebläse, insbesondere - jedoch nicht nur - Abgasgebläse und Frischluftzuführung zu schaffen, bei dem hitzeempfindliche Bauteile ausreichend gekühlt werden können.The object of the invention is therefore a heater with a fan, in particular - but not only - to create exhaust gas blowers and fresh air supply for the heat-sensitive components can be cooled sufficiently.
Erfindungsgemäß wird dies bei einem Heizgerät der eingangs erwähnten Art durch die kennzeichnenden Merkmale der unabhängigen Ansprüche erreicht.According to the invention, this is achieved in a heater of the type mentioned by characteristic features of the independent claims achieved.
Durch die vorgeschlagenen Maßnahmen des Anspruchs 1 kann sichergestellt werden, dass Frischluft, welche sich noch nicht im Heizgerät erwärmt hat, zur Kühlung des Gebläsemotors, der Gebläseelektronik und anderer elektrischen und elektronischen Bauteile verwendet werden kann. Hierbei ist einerseits vorteilhaft, dass die Frischluft noch relativ kühl ist, das heißt die Temperaturdifferenz zwischen Kühlmedium und zu kühlendem Medium ist relativ hoch, andererseits bewirkt die Platzierung im Strömungsweg einen guten Wärmeübergang; durch die relativ hohe Reynoldszahl ist der Wärmeübergangskoeffizient ebenfalls hoch.The proposed measures of claim 1 can ensure that Fresh air, which has not yet warmed up in the heater, to cool the blower motor, blower electronics and other electrical and electronic components can be. On the one hand, it is advantageous that the fresh air is still relatively cool, that The temperature difference between the cooling medium and the medium to be cooled is relative high, on the other hand the placement in the flow path causes a good heat transfer; due to the relatively high Reynolds number, the heat transfer coefficient is also high.

ist die Vorlauftemperatur nicht höher als 80°C, was zur Kühlung der Bauelemente ausreicht.

Durch die Merkmale des Anspruches 7 ergibt sich der Vorteil, dass die besonders niedrige

Die Erfindung wird nun anhand der Zeichnungen näher erläutert. Hierbei zeigt
- Fig. 1 ein erfindungsgemäßes Heizgerät und
- Fig. 2 ein alternatives erfindungsgemäßes Heizgerät.
- Fig. 1 a heater according to the invention and
- Fig. 2 shows an alternative heater according to the invention.
Ein Heizgerät 8 gemäß Fig. 1 verfügt über einen Brenner 1, der ein Brenngas-Luft-Gemisch verbrennt.
Die Abgase durchströmen den Brennraum 11, der sich in einer gekapselten Brennkammer 12 befindet.
Die Abgase werden in einem Wärmeaustauscher 2 abgekühlt und somit das Wasser eines
Wasserkreislaufs 3, der von einer Pumpe 13 angetrieben wird, erhitzt. Das abgekühlte Abgas gelangt
zu einem Lüfterrad 4 eines Gebläses und wird dann mit Überdruck durch eine Abgasleitung 9 ins Freie
gedrückt. Der Motor 6, das Netzteil 7 und die Elektronik 14 des Gebläses befinden sich außerhalb des
Abgasrohres 9 im Bereich des Frischlufteintritts. Die Frischluft gelangt durch eine Frischluftzuführung 5,
die konzentrisch um die Abgasleitung 9 angeordnet ist, in das Heizgerät 8. Frischluftzuführung 5 und
Abgasleitung 9 bilden somit ein koaxiales Abgassystem. Im Heizgerät 8 durchströmt die Frischluft eine
Unterdruckkammer 10, welche die Brennkammer 12 umschließt zum Brenner 1. Hierbei kühlt die
Frischluft den Motor 6, das Netzteil 7 und die Elektronik 14 des Gebläses, nimmt Abwärme der
Brennkammer 12 auf und gibt diese Energie später an den Wärmeaustauscher 2 ab.A
Es ist auch möglich, Frischluft und Abgas durch zwei getrennte Leitungen zu führen. In diesem Falle sollten die zu kühlenden Bauteile in die Frischluftleitung oder an den Eintritt der Frischluftleitung in das Heizgerät platziert werden.It is also possible to route fresh air and exhaust gas through two separate lines. In this case the components to be cooled should be in the fresh air line or at the entry of the fresh air line into the Heater are placed.
Während die Drehzahl von Wechselstromgebiäsen durch die Netzfrequenz auf 3000 U/min (50 Hz × 60 sec) begrenzt ist, können bei Gleichstromgebläsen deutlich höhere Drehzahlen erreicht werden. Die Drehzahl wird hierbei über ein Pulsweiten-Modulations-Signal vorgegeben. Dies erfordert eine Elektronik, welche das Signal vorgibt. Da in Heizgeräten mit Gebläseunterstützung durch aus in einer Unterdruckkammer Temperaturen über 120°C auftreten können, ist es von besonderer Bedeutung, die Elektronik zu kühlen, um Fehlfunktionen zu vermeiden. Eine Platzierung der Elektronik im Bereich des Frischlufteintritts garantiert Temperaturen, welche einen sicheren Betrieb der Elektronik gewährleisten und die Lebensdauer der Bauteile erhöht.While the speed of AC fans by the mains frequency to 3000 rpm (50 Hz × 60 sec) is limited, significantly higher speeds can be achieved with DC fans. The The speed is specified via a pulse width modulation signal. This requires one Electronics that provide the signal. Because in heaters with fan support through out in one Vacuum chamber temperatures can occur above 120 ° C, it is of particular importance that Cool electronics to avoid malfunctions. A placement of the electronics in the area of the Fresh air entry guarantees temperatures that ensure safe operation of the electronics and increases the life of the components.
Auch bei Heizgeräten mit einem Gebläse stromab des Brenners, bei dem das Brenngas-Luft-Gemisch durch den Brenner und das Abgas durch den Wärmeaustauscher gedrückt werden, ist die erfindungsgemäße Platzierung der wärmeempfindlichen Bauteile vorteilhaft.Also for heaters with a fan downstream of the burner, in which the fuel gas-air mixture through the burner and the exhaust gas through the heat exchanger is the placement of the heat-sensitive components according to the invention advantageous.
Ein Heizgerät gemäß Fig. 2 verfügt über einen Brenner 1, der ein Brenngas-Luft-Gemisch verbrennt.
Der Brenner 1 wird über ein Gebläse 4 mit Verbrennungsluft und eine Gasarmatur 19 mit Brenngas
versorgt. Die Abgase des Brenners 1 durchströmen den Brennraum 11, der sich in einer gekapselten
Brennkammer 12 befindet. Die Abgase werden in einem Wärmeaustauscher 2 abgekühlt und somit das
Wasser eines Wasserkreislaufs 3, der von einer Pumpe 13 angetrieben wird und bei dem Wasser über
die Rücklaufleitung 17 in das Heizgerät gelangt und über die Vorlaufleitung 18 das Heizgerät verlässt,
erhitzt. Das abgekühlte Abgas gelangt durch eine Abgasleitung 9 ins Freie gedrückt. Das Gebläse 4
verfügt über einen Antriebsmotor 6 und eine Steuerelektronik 14. Ferner besitzt das Heizgerät eine
Regelung 15, die unter anderem die Steuerelektronik 14 kontrolliert.2 has a burner 1 which burns a fuel gas-air mixture.
The burner 1 is powered by a
Die Steuerelektronik 14 und die Regelung 15 sind mit der Rücklaufleitung 17 verbunden, um eine
Kühlung zu gewährleisten. Eine gute Kühlung wird erreicht, wenn beispielsweise Kühlkörper der
Steuerelektronik 14 und der Regelung 15 über eine Wärmeleitpaste mit abgeflachten Rohrteilen der
Rücklaufleitung 17 verbunden werden.
