Abstract (en)

[origin: EP1775540A1] The manifold has a circular cross section and inwardly adjusted, flat oval passages (2) for receiving flat pipes. Deformed areas (3) are arranged in a center between adjacent passages and are designed flattened in a peripheral direction. The length of the flattened areas in the peripheral direction corresponds approximately to the length of longitudinal sides of the passages. Conically inclined surfaces (8, 9) are provided in a longitudinal direction of the manifold.
