Zusammenfassung:	The flat tube (1) is produced from one piece of strip. It has a turbulence creators (5a, 5b, 5c, 5d) stamped into it, facing inwards. The flat tube is in the form of a multi-chamber to one it has at least two chambers (3, 4), which are separated by a partition wall (2) formed from the single piece of strip from which the tube is made. Die Erfindung betrifft ein Flachrohr (1) für einen Wärmeübertrager, insbesondere für Kraftfahrzeuge, herstellbar aus einem einstückigen Blechband, mit nach innen gerichteten Einprägungen, so genannten Turbulatoren (5a, 5b, 5c, 5d). Es wird vorgeschlagen, dass das Flachrohr (1) als Mehrkammerrohr, d. h. mit mindestens zwei Kammern (3, 4) ausgebildet ist, welche jeweils durch eine aus dem Blechband geformte Trennwand (2) abgeteilt sind.
