Abstract

Die Erfindung betrifft ein metallisches Wärmeaustauscherrohr (1) mit auf der Rohraußenseite helixförmig umlaufenden, integral ausgeformten und durchgehend ausgebildeten Rippen (2), deren Rippenfuß (3) im Wesentlichen radial von der Rohrwandung (5) absteht, sowie mit zwischen jeweils benachbarten Rippen (2) sich befindenden Primärnuten (6). Im Bereich des Nutengrundes (7) der Primärnuten (6) ist mindestens eine hinterschnittene Sekundärnut (8) angeordnet. Diese Sekundärnut (8) ist zur Primärnut (6) hin durch ein Paar einander gegenüberliegender, aus Material jeweils benachbarter Rippenfüße (3) geformter Werkstoffvorsprünge (9) begrenzt. Diese Werkstoffvorsprünge (9) erstrecken sich kontinuierlich entlang der Primärnut (6). Der Querschnitt der Sekundärnut (8) wird in regelmäßigen Intervallen variiert, ohne dabei die Form der Rippen (2) zu beeinflussen. Zwischen den gegenüberliegenden Werkstoffvorsprüngen (9) ist ein Abstand (S), wobei dieser Abstand (S) in regelmäßigen Intervallen variiert wird, wodurch lokale Kavitäten (10) ausgebildet sind.
