Description

DEUTSCHESGERMAN

Bei Röhrenwärmetauschern wird bekanntlich das um die Rohre fließende Medium durch besondere, quer zu den Rohrachsen liegende Wände geführt. Zum Halten dieser Wände gegen Verschieben wurden bisher über einen Teil der Rohre Rohrhülsen geschoban oder ein Teil der Rohre durch Anker mit übergeschobenen Rohrhülsen u. dgl. ersetzt. Auf diese Weise nehmen alle für die Diistanzierung vorgesehenen Rohre am Wärmetauscher nicht teil. Dieser Austauschverlust ist besonders bei kleinen Apparaten erheblidh. With tubular heat exchangers, as is well known, the medium flowing around the tubes is Walls lying transversely to the pipe axes are guided. These walls were used to hold them against moving up to now pipe sleeves pushed over part of the pipes or part of the pipes with anchors pushed over Tube sleeves and the like replaced. In this way, all take for the distance provided Pipes not part of the heat exchanger. This loss of exchange is particularly noticeable in the case of small devices.

Erfindungsgemäß wird dieser Nachteil dadurch vermieden, daß zur Distanzierung Hülsen aus Streckmetall verwendet werden, wobei die Oberfläche der Hülsen entweder glatt oder gewellt sein kann. Durch die Verformung des Streckmetalls werden die einzelnen Stege gewunden, so daß die Distanzhülsen nur an verschiedenen Punkten an den Röhren' anliegen und die Rohrfläche ganz von der Strömung erfaßt wird. Die gewundenen Stege des Streckmetalls haben den Vorteil, daß das am Rohr vorbeifließende Medium durcheinandergewirbelt wird und ein höherer Wärmeübergang entstellt.According to the invention, this disadvantage is avoided in that sleeves made of expanded metal for spacing purposes can be used, the surface of the sleeves can be either smooth or corrugated. By the deformation of the expanded metal, the individual webs are wound, so that the spacer sleeves only different points on the tubes' and the pipe surface is completely covered by the flow. The twisted webs of the expanded metal have the Advantage that the medium flowing past the pipe is swirled around and a higher heat transfer disfigured.

Es ist zweckmäßig, daß die längeren Achsen des Rautenmusters des Streckmetalls parallel zur Längsachse der Hülsen verlaufen, da in diesem Fall die axiale Druckbelastung höher sein kann.It is useful that the longer axes of the diamond pattern of the expanded metal parallel to the longitudinal axis of the sleeves, since in this case the axial pressure load can be higher.

Außerdem ist es von Vorteil, die Streckmetalldistanzen im äußeren Rohrkranz des Röhrenbündels unterzubringen, da dort eine geringere Geschwindigkeit herrscht und der geringe Wärmeübergang durch die von Streckmetall hervorgerufene Wirbelung wesentlich verbessert wird.It is also advantageous to keep the expanded metal distances in the outer tube ring of the tube bundle to accommodate, since there is a lower speed and the low heat transfer through the vortex caused by expanded metal is significantly improved.
