ABSTRACT:
A method of manufacturing integrated manifolds for heat exchangers include providing hollow shape with a plurality of individual risers each having a substantially solid cross-section. Subsequently, the risers are reshaped by means of a reverse impact extrusion process into hollow risers. Finally, by perforating the wall of the hollow shape under the hollow risers, apertures are provided constituting inlets connecting the cavity of the hollow shape with the individual hollow risers.
