Description
DEUTSCHESGERMAN
Die Erfindung bezieht sich auf Glattrohr-Gegenstrom-Wärmeaustauscher mit bündelartig angeordneten Rohren. Dabei werden die gebündelten Rohre an ihren Enden in drucksteifen Rohrböden gehaltert. Das wärmeabgebende Medium niederen Druckes strömt um die Rohre und das wärmeaufnehmende Medium höheren Druckes durch die Rohre. Sehr enge und dünnwandige Rohre, wie sie etwa für Wärmeaustauscher bei Heißluftturbinenanlagen mit geschlossenem Kreislauf in sehr großer Zahl verwendet werden, lassen sich jedoch nicht in wirtschaftlicher Weise mit einer dickeren Rohrbodenplatte abdichtend und fest verbinden.The invention relates to smooth tube countercurrent heat exchangers with a bundle-like arrangement Pipes. The bundled tubes are held at their ends in pressure-resistant tube sheets. That heat-emitting medium of low pressure flows around the pipes and the heat-absorbing medium higher pressure through the pipes. Very narrow and thin-walled tubes, such as those used for heat exchangers are used in very large numbers in hot air turbine systems with closed circuit, however, cannot be economically sealed and firmly sealed with a thicker tube sheet associate.
Man hat deshalb auch schon daran gedacht, die Rohrboden durch gegenseitige Anlage der Rohrenden zu bilden, die dann nur von einem Rahmen oder Ring umgeben und zusammengehalten werden. Dabei sind die Rohrenden zum Überbrücken der Abstände mit aufgesetzten Muffen versehen oder entsprechend aufgeweitet und zugleich verformt, um ebene Seitenflächen zu bilden. Noch günstiger im Sinne eines möglichst kleinen Durchmessers solcher Rohrboden zur besseren Widerstandsfähigkeit gegen hohe Betriebsdrücke und größeren relativen Nutzleistung des Austauschers ist es jedoch, die Rohrenden ohne Verstärkungsmuffen oder Aufweitung bis zur unmittelbaren gegenseitigen Berührung in vorzugsweise versetzten Reihen zusammenzuführen.One has therefore already thought about the tube sheet by mutual contact of the tube ends to form, which are then only surrounded by a frame or ring and held together. Are there Provide the pipe ends with attached sleeves to bridge the gaps or widen them accordingly and at the same time deformed to form flat side surfaces. Even cheaper in the sense of one The smallest possible diameter of such a tube sheet for better resistance to high operating pressures and greater relative efficiency of the exchanger is, however, the pipe ends without reinforcing sleeves or expansion up to the immediate mutual contact in preferably offset Merge rows.
Von der letzten Art der Rohrbodenbildung ausgehend soll mit der Erfindung eine einwandfreie Lösung für das Problem der Überbrückung der durch die kreisrunde Rohrform bedingten kleinen zwickelartigen Zwischenräume sowie einer druckfesten Verbindung aller Rohrenden zu einem einheitlichen Gesamtkörper geschaffen werden. Dazu genügt keineswegs eine Lippenschweißung an den Stirnseiten, vielmehr müssen auf einer der Rohrbodenstärke entsprechenden Länge die Rohrzwischenräume vollkommen ausgefüllt und die Rohrenden miteinander verbunden sein. Dafür eignet sich aber kein Schweißverfahren, zumal dünnwandige Rohre bei derartig hohen Temperaturen sich leicht verziehen oder durchbrennen. Starting from the last type of tube sheet formation, the invention aims to provide a flawless solution for the problem of bridging the small gusset-like caused by the circular tube shape Interstices as well as a pressure-tight connection of all pipe ends to form a uniform overall body be created. A lip weld on the end faces is by no means sufficient for this, rather the pipe gaps must be completely at a length corresponding to the pipe sheet thickness filled out and the pipe ends connected to each other. But no welding process is suitable for this, especially since thin-walled pipes are easily warped or burned through at such high temperatures.
Ferner ist auch schon der Vorschlag gemacht worden, in den Rohrzwischenräumen drahtartige Füllstücke anzuordnen, die das Eindringen flüssigen Schweißgutes zwischen die Rohre verhindern und das Durchführen einer Lippenschweißung erleichtern sollen. Im Gegensatz dazu bedient sich die Erfindung der Maßnahme, solche FüMstücke anzuordnen, in der Weise, daß die Füllstücke einen den Rohrzwischenräumen entsprechenden Querschnitt mit dem Außenumfang der Rohre angepaßten, konkav gekrümmten Seiten haben und die verbleibenden Spalte praktisch Glattrohr - Gegenstrom.-WärmeaustauscherFurthermore, the proposal has already been made to insert wire-like filler pieces in the spaces between the pipes to be arranged that prevent the penetration of liquid weld metal between the pipes and the To make it easier to carry out a lip weld. In contrast, the invention makes use of it the measure of arranging such FüMstück in such a way that the filler pieces one of the pipe gaps Corresponding cross-section with the outer circumference of the tubes adapted, concavely curved Sides have and the remaining column practically smooth tube - countercurrent heat exchanger

überall gleich und so schmal sind (0,05 bis 0,2 mm), daß zum Abdichten und Verbinden vorgesehenes Hartlot bei entsprechender Arbeitstemperatur durch Kapillarwirkung in die Spalte hineingesaugt wird. Erst mit einer solchen Lötverbindung kann zum Unterschied von den bisherigen Schweißverbindungen eine wirklich einwandfrei dichte und für die vorkommenden Betriebsverhältnisse genügend drucksteife Rohrbodenbildung erreicht werden.everywhere the same and so narrow (0.05 to 0.2 mm) that what is provided for sealing and connecting Hard solder is sucked into the gap by capillary action at the appropriate working temperature. It is only with such a soldered connection that it differs from the previous welded connections a really perfectly tight one and sufficiently rigid against pressure for the operating conditions that occur Tube sheet formation can be achieved.
