FLAT PIPE COMPRISING A RETURN BEND SECTION AND A HEAT EXCHANGER CONSTRUCTED THEREWITH

摘要

The invention relates to a flat tube (1) comprising a return bend section (3), inside of which the flat tube (1) is bent back in such a manner that both planar tube sections (2a, 2b) thereof, which are connected to the return bend section, extend in a longitudinal direction with opposite flow-through directions (4a, 4b) and with longitudinal axes (5a, 5b) that are offset with regard to one another at least in the transverse direction (y). The invention provides that the return bend section (3) is formed in such a manner that a main bending axis (A) extends parallel to the flat tube plane and at a predeterminable angle to the tube longitudinal extension, whereby the flat tube plane is determined by the longitudinal and width extension of the flat tube (1).
