Claims (1)

<Desc/Clms Page number 1>  <Desc / Clms Page number 1>   Die Erfindung bezieht sich auf einen Wärmetauscher gemäss dem Oberbegriff des Patentan- spruches 1.  The invention relates to a heat exchanger according to the preamble of patent claim 1. Bei derartigen Wärmetauschern sind die Nadeln direkt an den Innenwänden der von den Brenngasen durchströmbaren Kammern angeordnet. Dabei ergibt sich jedoch der Nachteil, dass die Kammern nur mit einem sehr erheblichen Aufwand gereinigt werden können. Dadurch werden die Wartungsintervalle meist extrem lang angesetzt und der Wärmetauscher mit einem erheblich verminderten Wirkungsgrad betrieben.  In such heat exchangers, the needles are arranged directly on the inner walls of the chambers through which the fuel gases can flow. However, this has the disadvantage that the chambers can only be cleaned with very great effort. As a result, the maintenance intervals are usually set extremely long and the heat exchanger is operated with a significantly reduced efficiency. Ziel der Erfindung ist es, diese Nachteile zu vermeiden und einen Wärmetauscher der ein- gangs erwähnten Art vorzuschlagen, der sich durch eine einfache Wartung auszeichnet Erfindungsgemäss wird dies bei einem Wärmetauscher der eingangs erwähnten Art durch die kennzeichnenden Merkmale des Patentanspruches erreicht.  The aim of the invention is to avoid these disadvantages and to propose a heat exchanger of the type mentioned at the outset which is distinguished by simple maintenance According to the invention, this is achieved in a heat exchanger of the type mentioned at the outset by the characterizing features of the patent claim. Durch die vorgeschlagenen Massnahmen ist es auf einfache Weise möglich, die mit Nadeln ver- sehenen Wärmeleitregister aus den Kammern zu entfernen und in optimaler Lage zu reinigen, wo- nach die Wärmeleitregister wieder eingebaut werden können.  The proposed measures make it possible in a simple manner to remove the heat-conducting register provided with needles from the chambers and to clean them in an optimal position, after which the heat-conducting register can be reinstalled. Weiters ergibt sich der Vorteil, dass durch Austausch der Wärmeleitregister durch solche mit einer geänderten Nadelbestückung eine Anpassung an geänderte Betriebserfordernisse sehr ein- fach möglich ist.  Furthermore, there is the advantage that, by replacing the heat-conducting registers with those with a changed needle configuration, adaptation to changed operating requirements is very simple. Die Erfindung wird nun anhand der Zeichnung näher erläutert, die schematisch einen erfin- dungsgemässen Wärmetauscher zeigt.  The invention will now be explained in more detail with reference to the drawing, which schematically shows a heat exchanger according to the invention. Ein erfindungsgemässer Wärmetauscher 1 weist Stellfüsse 4 auf, mit denen sich Seitenwände 10, die einen Brennraum 5 begrenzen, abstützen.  A heat exchanger 1 according to the invention has adjustable feet 4 with which side walls 10, which delimit a combustion chamber 5, are supported. Der Wärmetauscher 1 weist Mittel- sowie Endglieder 6,7 auf, von denen das Endglied 7 mit einem Vorlauf-Anschluss 2 und einem Rücklaufanschluss 3 versehen ist.  The heat exchanger 1 has middle and end members 6, 7, of which the end member 7 is provided with a flow connection 2 and a return connection 3. Der Wärmetauscher 1 weist weiters von Brenngasen durchströmbare Kammern 9 auf, die von- einander durch die Glieder 6,7, 12 distanziert sind, wobei jede dieser Kammern 9 vom zu erwär- menden Medium, z. B. Wasser umströmt ist. In diese Kammern 9 sind Wärmeleitregister 8 einge- schoben, die mit Nadeln 11 bestückt sind. Zweckmässigerweise sind die Nadeln 11 in die Wärme- leitregister 8 eingeschraubt.  The heat exchanger 1 furthermore has chambers 9 through which fuel gases can flow and which are spaced apart from one another by the members 6, 7, 12, each of these chambers 9 being separated from the medium to be heated, eg. B. water is flowing around. Thermal conductors 8, which are equipped with needles 11, are inserted into these chambers 9. The needles 11 are expediently screwed into the heat-conducting register 8. Im Betrieb werden im Brennraum 5 mittels eines nicht dargestellten Brenners Brenngase er- zeugt, die durch die Kammern 9 und über die Wärmeleitregister 8 abströmen und an diese ihre Wärme abgeben.  In operation, combustion gases are generated in the combustion chamber 5 by means of a burner, not shown, which flow through the chambers 9 and via the heat conducting registers 8 and give off their heat to them. Da die Wärmeleitregister 8 in gutem wärmeleitenden Kontakt mit den Wänden der Kammern 9 bzw. der wasserführenden Gliedern 6,7, 12 stehen, fliesst die Wärme von den Wärmeleitregistern 9 in die Wände jeder Kammern 8 und von diesen in das diese umgebende wärmeaufnehmende Medium, z. B. Wasser.  Since the heat-conducting registers 8 are in good heat-conducting contact with the walls of the chambers 9 and the water-carrying members 6, 7, 12, the heat flows from the heat-conducting registers 9 into the walls of each chamber 8 and from these into the surrounding heat-absorbing medium, e.g. , B. water. Zu Wartungszwecken können die Wärmeleitregister 8 aus den Kammern 9 gezogen werden.  The heat conducting register 8 can be pulled out of the chambers 9 for maintenance purposes. Danach können die Wärmeleitregister 8 bequem gereinigt und danach wieder eingebaut werden. Thereafter, the heat register 8 can be easily cleaned and then reinstalled. PATENTANSPRUCH : Wärmetauscher mit von Brenngasen durchströmbaren und vom zu erwärmenden Medium um- strömbaren Kammern (9), in denen zur Verbesserung des Wärmeüberganges Nadeln (11) an- geordnet sind, dadurch gekennzeichnet, dass die Nadeln (11) an in die Kammern (9) ein- schiebbaren Wärmeleitregistern (8) angeordnet sind, die im eingeschobenen Zustand in gut wärmeleitendem Kontakt mit den Wänden der Kammern (9) stehen. **WARNUNG** Ende CLMS Feld Kannt Anfang DESC uberlappen**.  PATENT CLAIM: Heat exchanger with chambers (9) through which fuel gases can flow and around which the medium to be heated can flow, in which needles (11) are arranged to improve the heat transfer, characterized in that the needles (11) fit into the chambers (9) - Slidable heat-conducting registers (8) are arranged, which in the inserted state are in good heat-conducting contact with the walls of the chambers (9). ** WARNING ** End of CLMS field knows overlap beginning of DESC **.
