<p>A heat and/or matter exchanger for fluids, comprising a plurality of flat plates (1,13) and a plurality of spacing elements (6,6.R; 22,22.R), said flat plates (1,13) together with said spacing elements (6,6R; 22,22R) defining one or more primary heat and/or matter exchange chambers for the flowing of a primary fluid; said flat plates (1,13) together with said spacing elements (6,6.R; 22,22.R) also defining one or more secondary heat and/or matter exchange chambers for the flowing of a secondary fluid. The primary chambers are connected between themselves and with the outside by a plurality of primary openings (IP,UP) and are inserted in alternate sequence in the secondary chambers, which are connected between themselves and with the outside by a plurality of secondary openings (IS,US). The exchanger according to the present invention is characterized in that at least one of said primary and/or secondary chambers comprises two or more perforated flat plates (6,6.R) acting as spacing elements, each one with staggered through openings (11), so that the overlapping of said perforated flat plates forms contact zones (11.A) and through gaps (11.B) where the contact zones (11.A) ensure both a thermal and mechanical continuity between the perforated flat plates (6,6.R) and the through gaps (11.B) put in intercommunication at least some empty spaces obtained by the through gaps (11) inside each perforated flat plate. <IMAGE></p> |
