Description
<B>Zusatzpatent zum Hauptpatent Nr. 454 931</B> Wärmeübertrager Das Hauptpatent bezieht sich auf einen Wärme übertrager mit mindestens einem Rohr, das schrauben- linienförmig oder spiralförmig gewunden ist, wobei die Rohrwindungen in mindestens drei über den Umfang des Rohrgebildes verteilten Platten gehaltert sind, die sich in Ebenen erstrecken, welche sich im Bereich der Achse des Rohrgebildes schneiden.
Die vorliegende Erfindung bildet eine Weiterent wicklung des Erfindungsgegenstandes des Hauptpaten tes und ihr liegt die Aufgabe zugrunde, den Wärme übertrager auch für sehr hohe Temperaturen, nämlich höher als 500 C, und hohen Wärmeübergang von dem die Rohrwindungen umströmenden Medium auf das in den Rohrwindungen strömende Medium verwendbar zu machen. Gleichzeitig soll der Wärmeübertrager so aus gebildet werden, dass Rohrschwingungen vermieden wer den.
Erfindungsgemäss wird diese Aufgabe dadurch ge löst, dass ausser den die Windungen tragenden Halte rungsplatten zwischen diesen Platten vorgesehen sind, die sich ebenfalls in Ebenen erstrecken, die sich im Bereich der Achse des Rohrgebildes schneiden, wobei die radiale Breite der Platten um mindestens eine radiale Rohrteilung kleiner ist als die radiale Breite des Rohrbündels, und die Platten so gehalten sind, dass sie sich in Umfangsrichtung des Rohrgebildes nicht wesent lich verschieben können.
Unter radialer Breite ist die Abmessung der Platte bzw. des Rohrgebildes in radialer Richtung gemessen zu verstehen. Mit radialer Rohrteilung ist - in radialer Richtung gesehen - der Abstand von Rohrmitte zu Rohrmitte zweier benachbarter Rohre gemeint.
Ein Ausführungsbeispiel der Erfindung ist in der folgenden Beschreibung anhand der Zeichnung näher erläutert. Es zeigen: Fig. 1 eine Ansicht des. erfindungsgemässen Wärme übertragers, wobei das diesen umgebende Gehäuse im Axialschnitt dargestellt ist, Fig. 2 eine Draufsicht zu Fig. 1.
An einem zentralen Verdrängungskörper 30 sind drei Halterungsplatten 4, 5, 6 befestigt, die sich in Ebenen erstrecken, die sich im Bereich der Achse des Rohrgebildes schneiden. Die Platten 4, 5, 6 sind mit Löchern versehen, in die Rohrwindungen 2 einge schraubt sind, die an den Platten 4, 5, 6 fixiert sind.
Die Rohrwindungen bestehen aus schraubenlinienförmig gewundenen Rohren und bilden zehn ineinander ange ordnete Rohrwendeln mit unterschiedlichem Windungs- durchmesser. In den sektorartigen Räumen zwischen den drei Halterungsplatten sind über den Umfang des Rohr gebildes ungleichmässig verteilt fünfzehn Platten 60 vor gesehen, die sich in Ebenen erstrecken, die sich eben falls im Bereich der Achse des Rohrgebildes schneiden. Die Platten 60 sind ebenfalls mit Löchern versehen und je an mindestens einer der sie durchsetzenden Rohr windungen fixiert, zum Beispiel durch Schweissen.
Die radiale Breite der Platten 60 ist um mindestens eine radiale Rohrteilung kleiner als die radiale Breite des Rohrgebildes. Die Länge der Platten 60 in axialer Rich tung ist gleich derjenigen der Platten 4, 5, 6. Sowohl die dem Verdrängungskörper 30 am nächsten liegenden Platten 60 als auch die anderen, vom Verdrängungs körper entfernt befindlichen Platten 60, haben keine starre Verbindung mit dem Verdrängungskörper und auch nicht mit dem das Rohrgebilde umgebenden Ge häuse 61.
Dadurch, dass die Platten 60 auch nicht starr mit den Halterungsplatten 4, 5, 6 verbunden sind, wird es möglich, dass bei grossen Temperaturdifferenzen zwi schen Primär- und Sekundärmedium und bei hohem Wärmeübergang die Rohrabschnitte zwischen zwei Halte- rungsplatten sich verformen können und dabei von der idealen Form der Rohrwendel etwas abweichen, ohne dass dabei in den Rohren grosse Spannungen auftreten.
Die in einem sektorartigen Raum zwischen zwei Halterungs- platten befindlichen, in Umfangsrichtung des Rohrge bildes einander benachbarten Platten 60 schliessen unter schiedliche Sektorwinkel ein, wodurch sich unterschied liche Rohrstützweiten ergeben, die so gewählt werden, dass die freie Rohrlänge zwischen zwei Platten nicht zu Resonanzschwingungen angeregt werden kann, Bei dem beschriebenen Wärmeübertrager sind die Rohrwindungen schraubenlinienförmig ausgebildet; sie können auch spiralförmig verlaufen.
Es ist auch mög lich, Wärmeübertrager mit schraubenlinienförmigen Rohrwindungen herzustellen, bei denen die Rohrwindun gen auf einer Kegelfläche liegen.
Anstelle des beschriebenen Verschweissens der Plat ten 60 mit den Rohrwindungen 2 ist es auch möglich, :die Platten 60 über einen nachgiebigen Stab mit einer be nachbarten Halterungsplatte zu verbinden, so dass die Stäbe die Dehnbewegungen der Rohrwindungen infolge Temperaturänderungen und damit auch entsprechende, nicht wesentliche Bewegungen der Platten 60 zulassen.
<B> Additional patent to main patent no. 454 931 </B> Heat exchanger The main patent relates to a heat exchanger with at least one tube that is helically or spirally wound, with the tube turns in at least three plates distributed over the circumference of the tube structure are held, which extend in planes which intersect in the area of the axis of the pipe structure.
The present invention is a further development of the subject of the invention of the main patents and it is based on the object of the heat exchanger for very high temperatures, namely higher than 500 C, and high heat transfer from the medium flowing around the pipe windings to the medium flowing in the pipe windings to make usable. At the same time, the heat exchanger should be designed in such a way that pipe vibrations are avoided.
According to the invention, this object is achieved in that apart from the holding plates carrying the turns are provided between these plates, which also extend in planes that intersect in the area of the axis of the pipe structure, the radial width of the plates by at least one radial pipe division is smaller than the radial width of the tube bundle, and the plates are held so that they can not move wesent Lich in the circumferential direction of the tube structure.
Radial width is to be understood as the dimension of the plate or the pipe structure measured in the radial direction. With radial pipe division - seen in the radial direction - the distance from the center of the pipe to the center of the pipe of two adjacent pipes is meant.
An embodiment of the invention is explained in more detail in the following description with reference to the drawing. 1 shows a view of the heat exchanger according to the invention, the housing surrounding it being shown in axial section, FIG. 2 a plan view of FIG.
On a central displacement body 30, three mounting plates 4, 5, 6 are attached, which extend in planes which intersect in the region of the axis of the pipe structure. The plates 4, 5, 6 are provided with holes, are screwed into the pipe turns 2, which are fixed to the plates 4, 5, 6.
The pipe coils consist of helically wound pipes and form ten coiled pipes with different coil diameters. In the sector-like spaces between the three mounting plates, fifteen plates 60 are unevenly distributed over the circumference of the pipe structure, which extend in planes that intersect in the area of the axis of the pipe structure. The plates 60 are also provided with holes and each fixed to at least one of the pipe coils passing through them, for example by welding.
The radial width of the plates 60 is smaller by at least one radial pipe division than the radial width of the pipe structure. The length of the plates 60 in the axial direction is equal to that of the plates 4, 5, 6. Both the plates 60 closest to the displacement body 30 and the other plates 60 located away from the displacement body have no rigid connection with the displacement body and also not with the housing 61 surrounding the tubular structure.
Because the plates 60 are also not rigidly connected to the mounting plates 4, 5, 6, it is possible for the pipe sections between two mounting plates to deform in the event of large temperature differences between the primary and secondary medium and high heat transfer deviate somewhat from the ideal shape of the coiled tubing without causing great stresses in the tubes.
The plates 60, which are located in a sector-like space between two mounting plates and are adjacent to one another in the circumferential direction of the tube structure, include different sector angles, resulting in different tube support widths that are selected so that the free tube length between two plates does not cause resonance vibrations In the case of the heat exchanger described, the pipe windings are helical; they can also run spirally.
It is also possible, please include to produce heat exchangers with helical pipe windings, in which the Rohrwindun conditions are on a conical surface.
Instead of the described welding of the plates 60 with the pipe windings 2, it is also possible: to connect the plates 60 via a flexible rod to an adjacent mounting plate, so that the rods do not undergo the expansion movements of the pipe windings due to temperature changes and thus also corresponding, non-essential Allow movement of the plates 60.
