The invention relates to a soldered heat exchanger, especially a capacitor for a motor vehicle ventilation system, comprising a heat exchanger network made of tubes and ribs and at least one collector pipe made of a base ( 2 ) and a cover ( 3 ) and separating walls ( 8 ), whereby the base ( 2 ) and the cover ( 3 ) have edges ( 4, 5, 6, 7 ) which overlap on the longitudinal sides thereof. The base ( 2 ) receives the ends of the tubes and the separating walls ( 8 ) are fixed in relation to the cover ( 3 ) by means of a first and second shoulder ( 8 b , 8 c and a lug ( 8 a). According to the invention, groove-shaped recesses ( 3 b , 3 c) are arranged in the edges ( 6, 7 ) of the cover ( 3 ) in the region of the separating walls ( 8 ), wherein the shoulders ( 8 b , 8 c) of the separating walls ( 8 ) engage. A secure positioning of the separating walls in the collector pipe is obtained in addition to a leakage-free soldering of the capacitor. |
