KAISERLICHESIMPERIAL
PATENTAMT.PATENT OFFICE.
Die Erfindung betrifft eine Rohrschlange, wie sie zweckmäßig für Flüssigkeitserhitzer und ähnliche Vorrichtungen Verwendung finden kann. Es ist bekannt, solche Rohrschlangen mit abwechselnd aufeinander folgenden Verengungen und Erweiterungen zu versehen, um stellenweise den an der Außenwandv des Rohres vorbeistreichenden Heizgasen eine größere Heizfläche zu bieten, soThe invention relates to a pipe coil, as it can be expediently used for liquid heaters and similar devices. It is known to provide such coiled tubes with alternating constrictions and widenings in order to offer a larger heating surface in places to the heating gases passing on the outer wall v of the tube, see above
ίο daß eine raschere Erhitzung und Erwärmung der Flüssigkeit erzielt wird.ίο that faster heating and warming the liquid is achieved.
Zweck der Erfindung ist es, den Wirkungsgrad solcher Rohrschlangen dadurch zu erhöhen, daß die Übergangsstellen zwischen den Verengungen und Erweiterungen des Rohres eine plötzliche Richtungsänderung aufweisen, welcher die unter Druck stehende hindurchströmende Flüssigkeit nicht folgen kann, so daß sie in ihrer Strömung abge-The purpose of the invention is to increase the efficiency of such pipe coils by that the transition points between the constrictions and widenings of the pipe suddenly change direction have which the pressurized liquid flowing therethrough does not follow can so that they
lenkt wird. Jene Übergangsstellen sind daher scharfkantig ausgebildet. Wie Versuche ergeben haben, wird dadurch vermieden, daß die Flüssigkeit in gerader Richtung durch das Rohr strömt. Sie wird vielmehr in solcher Weise abgelenkt, daß Wirbelbewegungen in den RohrerweiterungeiT entstehen. Zweckmäßig ist es, die Rohrverengungen zylindrisch zu gestalten.is steered. Those transition points are therefore sharp-edged. As experiments show this prevents the liquid from flowing straight through the Pipe flows. Rather, it is deflected in such a way that vortex movements in the pipe expansion arise. It is useful to make the pipe constrictions cylindrical to design.
Auf der Zeichnung ist der Erfindungsgegenstand in der Gestalt eines durch einen Gasofen beheizten Flüssigkeitserhitzers dargestellt; es zeigt Fig. 1 einen Längsschnitt durch die Wasserheizvorrichtung nach A-A der Fig. 3; Fig. 2 ist ein Schnitt nach B-B der Fig. 3; Fig. 3 veranschaulicht einen Querschnitt nach C-C der Fig. 1.In the drawing, the subject matter of the invention is shown in the form of a liquid heater heated by a gas furnace; 1 shows a longitudinal section through the water heating device according to AA of FIG. 3; Fig. 2 is a section along BB of Fig. 3; FIG. 3 illustrates a cross section according to CC of FIG. 1.
Die in dem Ofen angeordnete Rohrschlange fghi, durch welche das zu erwärmende Wasser unter Druck hindurchfließt, besteht aus annähernd gleich langen, verengten, zylindrischen Teilen e und erweiterten Teilen n. Wie ersichtlich, sind die Übergangsstellen zwischen den Rohrverengungen e und den Rohrerweiterungen η scharfkantig ausgebildet. Durch die scharfen Kanten an den Übergangsstellen zwischen den Teilen η und e und durch die abwechselnde Einpressung und Freigebung des Wasserstromes werden Wirbel hervorgerufen, welche bewirken, daß die Wasserteilchen mit möglichst viel Fläche der dünnwandigen erweiterten Rohrstellen vor dem Weiterströmen in Berührung kommen. The pipe coil fghi, through which the water to be heated flows under pressure, is arranged in the furnace and consists of narrowed, cylindrical parts e and widened parts n of approximately the same length.As can be seen, the transition points between the pipe constrictions e and the pipe widenings η are sharp-edged . The sharp edges at the transition points between parts η and e and the alternating pressing in and releasing of the water flow create eddies, which cause the water particles to come into contact with as much area as possible of the thin-walled widened pipe points before they continue to flow.
