Abstract: A manifold for heat exchangers with a manifold segment having slots which are perpendicular to the tube axis and spaced in the longitudinal direction and separated by webs, into which hollow flat tubes can be inserted and joined to the contact surface of the respective slot. The webs each have a pair of stampings to strengthen the material on each side of each web and the webs are relatively flat in shape such that the cross-section of the manifold segment has a generally D-shaped profile. At least one baffle is inserted in the manifold segment, centered between a pair of adjacent slots. The baffle has a principle circular edge and a truncated edge so as to have a truncated circular profile substantially corresponding to the approximately D-shaped profile of the manifold segment.
