Abstract
Heat exchanger for recovering heat from the exhaust gases of a motor vehicle, in which the exhaust gases circulate between two manifolds delimited by respective caps and by the end walls of a cylindrical casing, passing in tubes which are elongated in the axial direction in the casing. The caps are produced by stamping from a thin sheet metal, which leads to a reduction in weight and in cost and allows the caps to remain fitted snugly by elasticity on the ends of the casing, until brazed.
