Abstract
In the heat exchanger for motor vehicles with ribbed flat tubes, the tube interior space thereof is each connected with headers, a first of which is arranged in the region of the first ends and a second is arranged in the region of the second ends of the flat tubes. The internal heat exchange fluid can be admitted to the flat tubes in an individual or group-wise sequence alternately at their first ends from the first header and at their second ends from the second header by each header comprising a supply and a return of the corresponding heat exchange fluid. The ends of the flat tubes opposed to their header have a U-shaped flow reverse in the flat tube.
