Description

DEUTSCHESGERMAN

Die Erfindung bezieht sich auf eine in Wärmetauscher eingebaute Rohrschlange, insbesondere eine in einem Niederdruck-Heißwasserspeicher eingebaute Hochdruckrohrschlange, in deren Windungen die Zähne von kammartig ausgebildeten, an mehreren Stellen ihres Umfanges angeordneten Versteif ungsblechen greifen. Bei einer bekannten Einrichtung wird die Rohrschlange durch Laschen gehalten, die durch entsprechende Bearbeitung von Profileisen gebildet und die nach dem Einlegen der Rohrschlange an die Rohre angebogen oder angestemmt werden. Der Einbau einer Rohrschlange in eine solche Halterung ist umständlich und der Ausbau sehr schwierig, insbesondere besteht aber die Gefahr, daß die Rohre beim Anstemmen der Laschen beschädigt werden.The invention relates to an in heat exchanger built-in coil, especially one built into a low-pressure hot water tank High-pressure pipe coil, in the turns of which the teeth of a comb-like design, on several Place their circumference arranged stiffening ungsblechen grab. At a known facility the pipe coil is held by brackets, which are formed by appropriate processing of profile iron and which are bent or crimped onto the pipes after the pipe coil has been inserted. The installation of a pipe coil in such a bracket is cumbersome and the removal very difficult, in particular, however, there is the risk that the tubes will be damaged when the tabs are caulked.

Die Erfindung beseitigt diese Schwierigkeiten. Erfindungsgemäß sind die Versteifungsbleche V-förmig gebogen und halten mittels ihrer Zähne, die durch im gleichen Abstand wie die Windungen der Schlange angeordnete Aussparungen gebildet sind, die Rohrschlange durch Federkraft fest.The invention overcomes these difficulties. According to the invention, the stiffening plates are V-shaped bent and held by means of their teeth, which pass through at the same distance as the coils of the serpent arranged recesses are formed, the coil tightly by spring force.

In der Zeichnung ist ein Ausführungsbeispiel der Erfindung dargestellt. Sie zeigt einen Niederdruck-Heißwasserspeicher mit eingebauter Hochdruckrohrschlange zum Teil im Längsschnitt.An exemplary embodiment of the invention is shown in the drawing. It shows a low-pressure hot water tank with built-in high pressure pipe coil, partly in longitudinal section.

Der Kessel des Heißwasserspeichers besteht aus dem Mantel 1, dem Boden 2 und dem Deckel 3. Diese Teile sind miteinander hart verlötet. An dem Mantel 1 sind je drei am Umfang gleichmäßig verteilte Abstandhalter 4 durch Hartlötung befestigt. Die zu einem Winkel gebogenen Abstandhalter 4 greifen in Aussparungen 5 von Versteifungsblechen 6 ein. Die Versteifungsbleche 6, die beispielsweise aus Federbronzeblech bestehen, sind zu einem V-förmigen Querprofil gebogen. Die durch die Aussparungen 5 gebildeten Zähne 7 greifen zwischen die Windungen 8 einer Rohrschlange 9 ein. Die Aussparungen sind den Abmessungen der Schlange so angepaßt, daß die Versteifungsbleche durch Zusammendrücken mittels geeigneter Spannvorrichtungen leicht zwischen die Windüngen eingesetzt werden können und nach dem Abziehen der Spannvorrichtungen die Windungen der Rohrschlange durch Federkraft festhalten. In die Versteifungsbleche ist in bekannter Weise je ein starker Draht 10 eingezogen, der verhindert, daß sich die einzelnen Windungen der Rohrschlange aus den Versteifungsblechen lösen.The boiler of the hot water storage tank consists of the jacket 1, the bottom 2 and the lid 3. These Parts are hard soldered together. On the jacket 1 are three spacers evenly distributed around the circumference 4 fixed by brazing. The spacers 4, which are bent at an angle, engage in Recesses 5 of stiffening plates 6. The stiffening plates 6, for example made of spring bronze sheet are bent into a V-shaped cross-section. The through the recesses 5 The teeth 7 formed engage between the turns 8 of a coil 9. The recesses are the Dimensions of the snake adjusted so that the stiffening plates by pressing together by means of suitable Jigs can be easily inserted between the windings and after being pulled off the tensioning devices hold the coils of the pipe coil by spring force. In the Stiffening plates are each drawn in a strong wire 10 in a known manner, which prevents that Loosen the individual turns of the pipe coil from the stiffening plates.

Dadurch, daß die Rohrschlange lediglich durch die Federkraft der Versteifungsbleche festgehalten wird, ist eine Beschädigung der Rohrschlange unmöglich, In Wärmetauscher eingebaute
Rohrschlange
Because the coil is only held in place by the spring force of the stiffening plates, damage to the coil is impossible. Built-in heat exchangers
