A method for the production of heat exchangers (10, 110, 210) of the so-called plate type, comprising the operative steps of : - juxtaposing a couple of substantially identical metal plates (12, 14),- fixing together said juxtaposed plates (12, 14) to one another by means of welding performed at respective perimetric sides (13a, 13b, 13c, 13d) , - further fixing together said juxtaposed plates to each other by means of a plurality of welding tracts (22), arranged in at least two alignments, parallel and adjacent to a couple of opposite perimetric sides (13a, 13c) of the plates themselves (12, 14), and at a pre-established spaced relationship from said sides, - introducing a fluid under pressure between said juxtaposed metal plates (12, 14), to form a hollow, substantially box-shaped body (17), in which an internal chamber (16) and two substantially tubular passages (16a, 16b), formed between said couple of opposite perimetric sides (13a, 13c) and the respective adjacent alignments of the welding tracts (22), are defined, said substantially tubular passages (16a, 16b) having an axis parallel to said opposite perimetric sides (13a, 13c) and being in fluid communication with said internal chamber (16), - cutting said hollow body (17) along said substantially tubular passages (16a, 16c) and in the direction of their axis, thus obtaining a hollow body (17) equipped, on opposite sides, with substantially semi-tubular passages (16c, 16d), open towards the outside of the body (17) itself, - associating with said substantially semi-tubular passages (16c, 16d), respective distributor duct (18) and collector duct (20).
La présente invention concerne un procédé destiné à la production d~échangeurs de chaleur (10, 110, 210) dits à plaques, qui comprend les étapes suivantes : - la juxtaposition d~une paire de plaques métalliques (12, 14) sensiblement identiques ; - l~assemblage desdites plaques juxtaposées (12, 14) en soudant leurs côtés périmétriques respectifs (13a, 13b, 13c, 13d) ; - l~assemblage desdites plaques juxtaposées en se servant d~une pluralité de trajets de soudage (22), agencés en deux alignements au moins, parallèles et adjacents à une paire de côtés périmétriques opposés (13a, 13c) appartenant aux plaques (12, 14), et selon un espacement pré-établi depuis lesdits côtés ; - l~introduction d~un fluide sous pression entre lesdites plaques métalliques juxtaposées (12, 14), afin de former un corps creux sensiblement en forme de boîte (17) dans lequel une chambre interne (16) et deux passages sensiblement tubulaires (16a, 16b), formés entre ladite paire de côtés périmétriques opposés (13a, 13c) et les alignements adjacents respectifs des trajets de soudage (22), sont définis, lesdits passages sensiblement tubulaires (16a, 16b) possédant un axe parallèle auxdits côtés périmétriques opposés (13a, 13c) et étant en communication fluidique avec ladite chambre interne (16) ; - la coupe dudit corps creux (17) le long desdits passages sensiblement tubulaires (16a, 16c) et dans la direction de leur axe, ce qui permet ainsi d~obtenir un corps creux (17) doté, sur les côtés opposés, de passages sensiblement semi-tubulaires (16c, 16d), ouverts vers l~extérieur du corps (17) ; - l~association respective avec lesdits passages sensiblement semi-tubulaires (16c, 16d) d~un conduit de distribution (18) et d~un conduit collecteur (20).
