Description
Einrichtung zur Nutzbarmachung der in den Abgasen der Brennkraftmaschine eines Fahrzeuges, insbesondere eines Luftfahrzeuges enthaltenen Wärme zu Heizzwecken Die Erfindung betrifft eine Einrichtung zur Nutzbarmachung der in den Abgasen der Brennkraftmaschine eines Fahrzeuges, insbesondere eines Luftfahrzeuges enthaltanen Wärme zu Heizzwecken, bei welcher die den einzelnen Zylindern der Brennkraftmaschine angeschlossenen Abgasstutzen durch eine rohrförmige Heizmittelleitung hindurchgeführt sind und von der diese Leitung durchströmenden und zu erwärmenden Frischluft umspült werden.Device for utilizing the in the exhaust gases of the internal combustion engine a vehicle, in particular an aircraft, contained heat for heating purposes The invention relates to a device for utilizing the in the exhaust gases Internal combustion engine of a vehicle, in particular an aircraft Heat for heating purposes, in which the individual cylinders of the internal combustion engine connected exhaust pipe passed through a tubular heating medium line and is washed around by the fresh air flowing through this line and being heated will.
Es ,ist bekannt, Heizmittelleitungen der erwähnten Art als einheitliches Rohr auszuführen, durch welches die einzelnen Abgasstutzen hindurchgeführt sind. Die Herstellung derartiger Einrichtungen ist aber infolge des verwickelten Aufbaues schwierig und kostspielig. Auch haftet diesen Einrichtungen der Nachteil an, daß sie infolge der ungleichmäßiger Erwärmung durch Wärmeleitung von den .einzelnen hoch erhitzten Abgasstutzen und durch Wärmeübertragung aus dem bedeutend kühleren Heizmittel unterschiedliche Formänderungen erleiden, die solche Ausmaße annehmen können, daß die Einrichtungen durch die dadurch hervorgerufenen Spannungen zerstört werden. Sie bieten ferner nicht die Möglichkeit, einzelne Abgasstutzen, die schadhaft geworden sind, einfach und billig auszuwechseln.It is known, heating medium lines of the type mentioned as a unit Execute pipe through which the individual exhaust ports are passed. The manufacture of such devices is, however, due to the intricate structure difficult and costly. These facilities also have the disadvantage that they as a result of the uneven heating by conduction of the .individual highly heated exhaust pipe and through heat transfer from the significantly cooler one Heating means suffer different changes in shape that assume such dimensions can destroy the facilities due to the voltages caused thereby will. They also do not offer the possibility of individual exhaust gas connections that are defective have become easy and cheap to replace.
Gemäß der Erfindung werden diese Nachteile dadurch vermieden, daß die Heizmittelleitung in dem Bereich, in welchem sie von den Abgasstutzen durchsetzt wird, aus mehreren getrennt voneinander hergestellten, mit ihren einander zugekehrten Enden gasdicht verbundenen Rohrstücken gebildet wird, deren jedes von einem oder mehreren Abgasstutzen durchsetzt und mit diesen gasdicht verbunden ist. In weiterer Ausgestaltung der Erfindung wird vorgeschlagen, daß die Rohrstücke .der Heizmittelleitung mindestens an ihren Enden derart ausgebildet sind, daß die einander zugekehrten Enden je zweier Rohrstücke gasdicht ineinandersteckbar sind. Dies geschieht dadurch, daß die gasdicht ineinandersteckbaren Enden benachbarter Rohrstücke konisch ausgebildet sind.According to the invention, these disadvantages are avoided in that the heating medium line in the area in which it is penetrated by the exhaust gas nozzle is made from several separately produced, with their facing each other Gas-tight ends connected pipe pieces is formed, each of which penetrated by one or more exhaust gas connections and connected to them in a gas-tight manner is. In a further embodiment of the invention it is proposed that the pipe sections .The heating medium line are designed at least at their ends in such a way that the facing ends of two pieces of pipe can be plugged into one another in a gas-tight manner. This is done in that the gastight nested ends of adjacent ones Pipe sections are conical.
Der durch die Erfindung erzielte Fortschritt besteht darin, daß jeder Abgasstutzen mit seinem Rohrstück, durch welches er hindurchgeführt ist, ein Bauelement bildet. Hierdurch wird eine vereinfachte Herstellung dieser einzelnen Bauelemente und sein müheloser Zusammenbau der ganzen Anlage erreicht; auch sind Auswechselungen einzelner schadhaft gewordener Bauelemente ohne großen Arbeitsaufwand möglich. Weiterhin werden durch die Mehrteiligkeit der Heizmittelleitung die eingangs erwähnten Formänderungen infolge der unterschiedlichen Erwärmung von der elastischen Verbindung aufgenommen, so daß sich schädliche Spannungen nicht ausbilden können.The advance achieved by the invention is that everyone Exhaust gas nozzle with its pipe section, through which it is passed, a component forms. This simplifies the manufacture of these individual components and achieved its effortless assembly of the whole plant; also are substitutions Individual components that have become defective are possible without a great deal of work. Farther the above-mentioned changes in shape are due to the multi-part nature of the heating medium line absorbed by the elastic connection due to the different heating, so that harmful tensions cannot develop.
Die Zeichnung zeigt ein Ausführungsbeispiel der Erfindung im Längsschnitt.The drawing shows an embodiment of the invention in longitudinal section.
An der Brennkraftmaschine i sind die Abgasstutzen 2 befestigt. Jeder Abgasstutzen ist durch ein Rohrstück 3a, 3b, 3, quer hindurchgeführt, wobei die Durchtrittsstellen beispielsweise durch Schweißen gasdicht gemacht werden. Die auf diese Weise erzielten, aus Abgasstutzen und Rohrstück bestehenden Bauelemente werden einzeln. hergestellt. Die Rohrstücke 3" 3b und 3, sind mit ihren einander zugekehrten Enden aneinander festgelegt und an das Zuleitungsrohr 5 und an das Ableitungsrohr 4 angeschlossen, derart, daß sie zusammen mit diesem eine einzige durchgehende Leitung für das Heizmittel bilden. Gemäß dem dargestellten Ausführungsbeispiel sind die gasdicht ineinandersteckbaren Enden benachbarter Rohrstücke 5, 3" 3r. 3 und 4 konisch ausgebildet.The exhaust gas nozzles 2 are attached to the internal combustion engine i. Each exhaust pipe is passed transversely through a pipe section 3a, 3b, 3, the passage points being made gas-tight, for example by welding. The components obtained in this way, consisting of exhaust gas nozzle and pipe section, are made individually. manufactured. The pipe sections 3 " 3b and 3 are fixed with their ends facing each other and connected to the supply pipe 5 and to the discharge pipe 4 in such a way that they together with this form a single continuous line for the heating means. According to the illustrated embodiment, the ends of adjacent pipe sections 5, 3 ″ 3r which can be plugged into one another in a gas-tight manner. 3 and 4 conical.
