STRUCTURED HEAT EXCHANGER AND METHOD FOR ITS PRODUCTION

The exchanger tube has integral external ribs (6) running around the outside of the tube in a helical-line-shaped manner. Roll mandrels (10, 20, 30) are fitted at a free end of a roll mandrel rod (40) and are mounted rotatably with respect to each other, where the mandrels are to be positioned in a...

Beschreibung
Zusammenfassung:	The exchanger tube has integral external ribs (6) running around the outside of the tube in a helical-line-shaped manner. Roll mandrels (10, 20, 30) are fitted at a free end of a roll mandrel rod (40) and are mounted rotatably with respect to each other, where the mandrels are to be positioned in a working region of roll tools (50, 60, 70). Tertiary grooves in notched internal ribs (2) of the tube are structured on sides, where the internal ribs are crossed over an entire circumference of the tube by spaced-apart secondary grooves. An independent claim is also included for a method of producing a structured heat exchanger tube.
