Abstract

Die Erfindung betrifft ein Verfahren zur Herstellung eines Wärmeaustauschrohres (1) mit einer hochporösen Oberflächenstruktur, insbesondere zur Verdampfung von Flüssigkeiten aus Reinstoffen oder Gemischen auf der Rohraußenseite.
Das Verfahren geht aus von einem Walzvorgang, durch den auf der Rohraußenseite schraubenlinienförmige Rippen (2) erzeugt werden, die ihrerseits in mehreren Stauchschritten mittels zahnradartiger Stauchscheiben (7, 8) derart verformt werden, daß die gebildeten Auskragungen (12a, 12b) jeweils einen Deckel (3a) für die zwischen den Rippen (2) befindlichen Kanäle (3) formen. Die hohe Porosität wird durch die verbleibenden Poren (13) und/oder Schlitze (14) erreicht.
