Embodiment Construction
[0021] figure 1 In the figure is a charge air cooler 1 according to the invention, which consists of a heat exchanger core 2 and air boxes 3 , 4 arranged on both sides. The heat exchanger core 2 consists of flat tubes 5 and corrugated fins arranged between the flat tubes and through which ambient air flows. The tubes 5 lead into the air boxes 3 , 4 and are brazed together with them and the corrugated fins 6 . All parts such as tubes 5, wave fins 6 and air boxes 3, 4 are made of aluminum alloy. Each air box is a single whole and is divided into three sections (take air box 4 as an example), namely connecting pipe 7, cylindrical part 8 (non-cylindrical) and tapered or gradually flattened, with a The portion 9 of the longitudinal groove 10 extends in the longitudinal direction of the air box 4 . The connecting pipe 7 has a straight portion 7a completely centered and connected to the straight air box portion 8, and a bent portion 7b bent by about 90° to 120°. The air box 3 is ...
