Abstract (en)
[origin: EP0326813A1] The heat exchanger consists of a plurality of flat tubes (1) which are aligned with their side faces mutually parallel and are held in a leakproof fashion with both ends in corresponding openings of tube bottoms (3). In the region of the plane of the tube bottoms (3), there is provided at least one supporting web (5), which extends between the parallel tube walls (4) of the flat tubes (1) and is formed by lugs (6, 6') which are stamped from the tube wall (4) and bent inwards. Owing to these measures, the flat tubes are more stably formed in the region in which denting is to be feared because of the pressure forces of the tube bottoms. <IMAGE>
