Flat tube with a transverse offset - reversal arc section and thus heat exchanger constructed

摘要

The invention relates to a flat tube (1) with at least one U-bend section (3) in which the tube is bent such that its two flat tubular sections (2a, 2b), which are adjacent to the U-bend section, in their longitudinal direction have opposite directions of flow (4a, 4b) and longitudinal axes (5a, 5b) which are offset in relation to each other at least in the transverse direction (4). The flat tube transverse axis (7) forms an angle of no more than 45 DEG with a plane which is parallel to the longitudinal and transverse direction and vertical to a direction of stacking.
