ABSTRACT:
A stamped manifold for a heat exchanger includes a central portion having a plurality of mating tubular members for connection to tubes of a heat exchanger. The manifold includes a plurality of folds disposed between the mating tubular members to form a pair of channels below a plane of the central portion and a central fold above the plane of the central portion. The manifold includes a first extension member extending from a side edge of the central portion and a second extension member extending from another side of the central portion and opposing the first extension member. The free ends of the first extension member and the second extension member are disposed in the pair of channels in contact with the central fold and secured in place to define a first fluid conduit and a second fluid conduit.
