A manifold (12) for heat exchangers with a manifold segment (14) having longitudinal spaced slots (20-26) for receiving flat tubes (50-56) separated by webs (30-34). The webs (30-34) each have a pair of depressions (90a, 90b-94a, 94b) to strengthen the material on each side of each relatively flat web (30-34) such that the cross section of the manifold segment (14) has a generally D-shaped profile. At least one baffle (70) is inserted in the manifold segment (14), centered between a pair of adjacent slots (20-26). The baffle (70) has a principle circular edge (70a) and a truncated edge (70b) to correspond to the approximately D-shaped profile of the manifold segment (14) and an outwardly extending lip (72) over a portion of its perimeter at the principle circular edge (70a). The lip (72) has projections (72b) extending from its ends, dimensioned to provide an interference fit between the baffle (70) and the manifold segment (14). |
