Abstract

Die Erfindung betrifft ein Wärmeaustauschrohr (4) mit berippter Innenoberfläche, die in Umfangsrichtung in mindestens zwei Zonen (Z1, Z2, ..., Zn) unterteilt ist, die sich in mindestens zwei Zonenklassen (K1, K2,..., Kj, Kj+1,..., Km) unterscheiden lassen.
In Zonen mindestens einer Zonenklasse (K1, K2, ..., Kj) verlaufen Rippen (1) mit einer Rippenhöhe h1 und unter einem Steigungswinkel α1 zur Rohrlängsrichtung.
In Zonen mindestens einer weiteren Zonenklasse (Kj+1, Kj+2, ..., Km) verlaufen Rippen (2) mit einer Rippenhöhe h2 unter einem Steigungswinkel α2, die von unter einem Steigungswinkel α3 verlaufenden Rippen (3) einer Rippenhöhe h3 gekreuzt werden (α3≠α2).
Vorzugsweise sind h2, h3 ≤ h1+(Fig. 5).
