Abstract

Die Erfindung betrifft beidseitig strukturierte Wärmeaustauscherrohre (1) mit ausgezeichneten Wärmeübertragungseigenschaften, die auf der Außenseite Vertiefungen (3, 7) und auf der Innenseite Rippen (5) bestimmter Abmessungen aufweisen.
Die für verschiedene Verfahrensvarianten verwendeten Strukturierungswerkzeuge werden so eingestellt, daß sie nicht nur fluchtende, kontinuierliche Nuten (3) und nicht-fluchtende, voneinander beabstandete Vertiefungen (7) sondern auch sekundäre Strukturen erzeugen können. Die vorzugsweise mit glatten Enden (1a) und glatten Zwischenstücken (1b) versehenen Wärmeaustauscherrohre (1) werden insbes, in Rohrbündelwärmeaustauschern eingesetzt (Fig. 3).
