KLASSE 17/.CLASS 17 /.
Vorliegende Erfindung betrifft Wärmeaus- ·.;■· tauschvorrichtungen, bei denen Einsätze in den Rohren angeordnet sind.The present invention relates to heat exchange devices in which inserts in the tubes are arranged.
Vermittels dieser Einsätze soll die durch das Rohr strömende .gasförmige oder tropfbare Flüssigkeit durcheinandergewirbelt und ein schnellerer Wärmeausgleich zwischen ihr und der Rohrwand erzielt werden. Die Erfindung ist in zwei Ausführungsformen in den ίο Fig. ι bis 4 dargestellt.By means of these inserts, the .gaseous or dripping Fluid mixed up and a faster heat exchange between it and the pipe wall can be achieved. The invention is in two embodiments in FIGS ίο Fig. ι to 4 shown.
: Zur Erreichung dieses Zweckes werden Quer- : To achieve this purpose, transverse
stege α eingesetzt, die mit ihren Enden die Rohrwand berühren. Diese Querstege können untereinander mittels Längsstreifen b aus Blech oder Draht verbunden sein oder auch mit diesen aus einem Stück bestehen.webs α used, which touch the pipe wall with their ends. These transverse webs can be connected to one another by means of longitudinal strips b made of sheet metal or wire or can also consist of one piece with them.
Die das Rohr durchströmende Flüssigkeit
wird gegen die Querstege prallen und wirbel-. bildend aus der. ursprünglichen Strömungsao
richtung abgelenkt werden. Jedes einzelne Teilchen wird infolge' der Durcheinanderwirbelung
sehr oft mit den gut wärmeleitenden Querstegen und der Rohrwand in Berührung kommen; es wird somit in kurzer
ag Zeit ein Temperaturausgleich zwischen Rohrwand
und Flüssigkeit stattfinden.
/ Die Anwendung dieser Einsätze ist von
■ bedeutendem Vorteil bei Oberflächenkondensatoren, Röhrenvorwärmern, Überhitzern und
ähnlichen Vorrichtungen.The liquid flowing through the pipe will collide against the crosspieces and swirl. forming from the. original direction of flow are deflected. As a result of the turbulence, each individual particle will very often come into contact with the transverse webs, which are a good conductor of heat, and the pipe wall; a temperature equalization between the pipe wall and the liquid will take place in a short time.
/ The application of these inserts is of significant ■ advantage in surface condensers, tube preheaters, superheaters and similar devices.
Bei Dampfüberhitzern z. B. wird eine Tropfenbildung mitgerissener Wasserteile vollkommen verhindert, da jeder Wassertropfen und jedes Wasserbläschen schon beim Eintritt in das Rohr an den Querstegen zerschellt. Eine vollständige Überhitzung des Dampfes auf die Rohrtemperatur wird demnach im kürzeren Rohr bezw. vermittels kleinerer Rohrheizfläche erfolgen als bei Rohren ohne diese Einsätze.For steam superheaters z. B. a drop formation of entrained water parts is complete prevents every drop of water and every water bubble from shattering on the crosspieces as soon as it enters the pipe. A complete overheating of the steam to the pipe temperature is therefore in the shorter tube respectively. by means of a smaller pipe heating surface than with pipes without these stakes.
Die Einsätze sind leicht in das Rohr einzuführen und erhöhen das Gewicht des Rohres nicht wesentlich. .The inserts are easy to insert into the pipe and add to the weight of the pipe not essential. .
