ABSTRACT:
An integral manifold for a heat exchanger is formed from a hollow shape having a plurality of individual risers, initially having substantially solid cross-sections and subsequently reshaped by means of a reverse impact extrusion process into hollow risers. The walls of the hollow shape under the hollow risers are perforated, thus forming apertures constituting inlets connecting the cavity of the hollow shape with the individual hollow risers.
