A new method of manufacturing of integrated manifolds for heat exchangers is disclosed. A hollow shape (2) with a plurality of individual risers (23) having a substantially solid cross-section is provided and subsequently the risers (23) are reshaped by means of a reverse impact extrusion process into hollow risers (3). Finally, by perforating the hollow shape's (2) wall under the hollow risers (3), apertures are provided constituting inlets connecting the cavity of the hollow shape (2) with the individual hollow risers (3). |
