Abstract (en)
[origin: EP1770250A2] The exchanger has inner and outer flow areas for exhaust gas (G) and cooling water (W), respectively. The inner area is formed by a hose line (10) and the outer area is formed between the hose line and a casing line (2), where the hose line extends concentrically to the casing line and has annular wave-shaped corrugation. Spacing units (16, 17, 18) are arranged in the outer flow area between the casing line and the hose line. An axial curved area is formed by the deformation of the hose and casing lines, and the spacing units are formed in a ring or helical shape.
