Beschreibung description
Die Erfindung betrifft ein Heizgerät wie im Oberbegriff des Anspruchs 1 umschrieben. Die Herstellung eines solchen Heizgeräts erfordert namentlich für die Herstellung des Wärmetauschers in der Regel einen hohen Kostenaufwand, da eine grosse Anzahl von Teilen durch Schweissen miteinander verbunden werden muss. Die Erfindung beabsichtigt, dieses Problem zu beheben und noch weitere Verbesserungen an dem Heizgerät und namentlich an dessen Wärmetauscher vorzunehmen. The invention relates to a heater as described in the preamble of claim 1. The manufacture of such a heater, particularly for the manufacture of the heat exchanger, generally requires a high cost because a large number of parts have to be connected to one another by welding. The invention intends to solve this problem and to make further improvements to the heater and in particular to its heat exchanger.
Dies wird erfindungsgernäss mittels der Massnahmen nach dem Kennzeichen des Anspruchs 1 erreicht. This is achieved according to the invention by means of the measures according to the characterizing part of claim 1.
Indem der Wärmetauscher in einem einzigen Arbeitsgang hergestellt wird, wird eine erhebliche Einsparung an Fertigungskosten erzielt. By manufacturing the heat exchanger in a single operation, a considerable saving in manufacturing costs is achieved.
Vorzugsweise sind zwischen Lamellen des Extru-sionsteils Leitplatten angebracht. Dadurch wird der Durchlauf der heissen Gase durch den Wärmetauscher erheblich verlängert, was die Wärmeübertragung auf den das Wärmetransportmediüm führenden Teil verbessert. Vorzugsweise verlaufen die Leitplatten einigermassen schräg nach unten, um etwaiges Kondenswasser abzuleiten. Die Leitplatten können durch Schweissen oder auf ähnliche Weise fest angebracht werden, oder aber lose hineingelegt werden. Guide plates are preferably attached between lamellae of the extrusion part. As a result, the passage of the hot gases through the heat exchanger is considerably lengthened, which improves the heat transfer to the part carrying the heat transfer medium. The guide plates preferably run somewhat obliquely downwards in order to discharge any condensed water. The guide plates can be firmly attached by welding or in a similar manner, or can be placed loosely in them.
Der das Wärmetransportmedium führende Teil kann mit Längsrippen versehen sein, um die Wärmeübertragung auf das Wärmetransportmedium zu verbessern. Der das Wärmetransportmedium führende Teil kann mit quer zu der Mediumtransportvorrichtung verlaufenden Leitwänden versehen sein, um die Wegstrecke des Mediumtransports durch den Wärmetauscher zu verlängern. The part carrying the heat transport medium can be provided with longitudinal ribs in order to improve the heat transfer to the heat transport medium. The part guiding the heat transport medium can be provided with guide walls running transversely to the medium transport device in order to extend the distance of the medium transport through the heat exchanger.
Die Erfindung wird anhand der Figuren näher erläutert. The invention is illustrated by the figures.
Fig. 1 ist eine perspektivische Ansicht eines er-findungsgemässen Heizgeräts, teils aufgeschnitten; 1 is a perspective view of a heating device according to the invention, partly cut away;
Fig. 2 ist eine Querschnittsansicht durch das Gerät aus Fig. 1; Fig. 2 is a cross-sectional view through the device of Fig. 1;
Fig 3 ist eine Perspektivansicht einer alternativen Ausführungsform. 3 is a perspective view of an alternative embodiment.
Das Heizgerät 1 zeigt einen Brenner 2, einen Wärmetauscher 3, der aus einem heisse Gase führenden Teil 4 und einem Wärmetransportmedium führenden Teil 5 besteht. An das Gerät ist eine Zu-fuhrleitung 7 für das Heizungssystem und eine Rücklaufleitung 6 angeschlossen. Der heisse Gase führende Teil besteht aus parallelen Lamellen 8, 8', 8"..., die mittels der Wand 9 miteinander verbunden sind. Die Wand 9 und die Lamellen 8, 8', 8"... sowie Längsrippen 12,12', 12"... des das Wärmetransportmedium führenden Teils 5 sind als ein Ganzes durch Extrusion aus Aluminium hergestellt. Der Wärmeaustauscher kann auch aus mehreren solchen Ex-trusionsteilen zusammengesetzt sein. Auf die übliche Weise wird durch die Kraftstoffleitur zum Beispiet Gas, 10 Kraftstoff zugeführt und im Brenner 2 verbrannt. Die heissen Gase bewegen sich danach senkrecht nach unten entlang den Lamellen 8, 8', 8"... und heizen dabei die Wand 9, die ebenfalls eine Begrenzungswand des das Wärmetransportmedium führenden Teils 5 bildet. Nach dem Gegenstromprinzip wird das Wärmetransportmediüm in Aufwärtsrichtung durch den Teil 5 transportiert. Weil die Verbrennungsgase abwärts strömen, kann Kondenswasser einfach abgeleitet werden. The heater 1 shows a burner 2, a heat exchanger 3, which consists of a hot gas-carrying part 4 and a heat transport medium part 5. A supply line 7 for the heating system and a return line 6 are connected to the device. The hot gas-carrying part consists of parallel fins 8, 8 ', 8 "... which are connected to one another by means of the wall 9. The wall 9 and the fins 8, 8', 8" ... and longitudinal ribs 12, 12 ', 12 "... of the part 5 carrying the heat transport medium are produced as a whole by extrusion from aluminum. The heat exchanger can also be composed of several such extrusion parts. In the usual way, the fuel line becomes gas, 10 fuel supplied and burned in the burner 2. The hot gases then move vertically downwards along the fins 8, 8 ', 8 "... and thereby heat the wall 9, which likewise forms a boundary wall of the part 5 carrying the heat transfer medium. According to the countercurrent principle, the heat transport medium is transported upwards through part 5. Because the combustion gases flow downwards, condensed water can easily be drained off.
Gemäss Fig. 2 sind in dem heisse Gase führenden Teil 3 zwischen den Lamellen 8, waagrechte Leitplatten 11,11 ', 11 "... angebracht, so dass die heissen Gase eine mäanderförmige Strecke durch den Wärmetauscher zurücklegen müssen. Dank dieser Massnahme ist die Strecke für die heissen Gase erheblich verlängert und wird infolgedessen die Wärmeübertragung verbessert. Zu einem entsprechenden Zweck können gemäss Fig. 3 in dem das Wärmetransportmediüm führenden Teil 5 zwischen den senkrecht verlaufenden parallelen Rippen 12, 12' 12"... ebenfalls schräg stehende Leitplatten 13, 13', 13"... angebracht sein. 2, horizontal guide plates 11, 11 ', 11 "... are fitted in the hot gas-carrying part 3 between the fins 8, so that the hot gases have to travel a meandering distance through the heat exchanger. Thanks to this measure, the 3 for the hot gases is considerably lengthened and, as a result, the heat transfer is improved. For a corresponding purpose, according to FIG. 3, in the part 5 guiding the heat transport medium between the perpendicular parallel ribs 12, 12 '12 "... also inclined guide plates 13 , 13 ', 13 "... be attached.
Die Verbrennungsgase treten durch einen Aus-lass aus, während das Kondenswasser über eine Kondenswasserleitung 21 abgeleitet wird. Die Konstruktion dieses Wärmetauschers .ist sowohl auf kondensierende wie auf nicht-kondensierende Kessel anwendbar. The combustion gases exit through an outlet, while the condensed water is discharged via a condensed water line 21. The construction of this heat exchanger is applicable to both condensing and non-condensing boilers.
