Abstract (en)

[origin: DE10306848A1] The flat tube (1) has a bent over section (3) so that connected sections (2a,2b) have opposite flow directions (4a, 4b) and mutually offset longitudinal axes (5a, 5b). The bent over section is formed so that a main bend axis (A) is parallel to the plane of the flat tube and at a definable angle to the pipe length, whereby the flat tube plane is defined by the length and width directions of the flat tube. An independent claim is also included for the following: (a) a gas cooler with an inventive device (b) and an evaporator with an inventive device.
