| 摘要 |
The invention relates to a heat exchanger, especially for motor vehicles, comprising a soldered heat exchanger network made of flat pipes ( 2, 3 ) and corrugated ribs ( 1 ). A liquid and/or vaporous-type medium can flow through the flat tubes ( 2, 3 ) and air can circulate around the corrugated ribs. One corrugated rib respectively comprises two surfaces ( 4, 5 ) which are arranged in an essentially parallel manner in relation to each other and which are connected respectively by an arch-shaped piece ( 6 ) which is soldered to a flat pipe, said arch-shaped piece comprising three sections ( 6 a , 6 b , 6 c) which have different curvatures.
