Abstract: Manifold with integrated pipe for a heat exchanger A manifold for, e.g. a motor vehicle heat exchanger, has a first part formed from a shaped metal sheet and featuring a bottom and two lateral walls folded face-to-face, at least one of which is provided with an aperture for fixing a pipe there. A second part is formed from a shaped metal sheet and able to be fitted onto the lateral walls of the first part to form a cover opposite the bottom of this first part. Either the first part or the second part has a manifold plate. The first part, the second part and the pipe are assembled by brazing.
