Abstract

Abstract Translated from French Echangeur à plaques comprenant une multiplicité de plaques métalliques (10-15) juxtaposées et séparées par des intervalles (A, B), un intervalle sur deux (A) étant destiné à la circulation d'un premier fluide et les autres intervalles (B) étant destinés à la circulation d'un second fluide sensiblement parallèlement au premier, chaque plaque étant reliée à sa périphérie aux deux plaques voisines de manière étanche, de manière à obturer, tout au moins partiellement lesdits intervalles (A, B) tout en ménageant des orifices d'admission et de sortie pour lesdits fluides, lesdites plaques étant assemblées par paires (10-11, 12-13, 14-15) par soudure linéaire (16, 17) dans deux zones extrêmes opposées des plaques de chaque paire, caractérisé en ce qu'une plaque (14) au moins par paire comporte une aile (20), au moins dans l'une desdites zones extrêmes et au voisinage de ladite soudure (16), repliée sensiblement à l'équerre et raccordée dans sa zone marginale libre à une plaque (13) en vis-à-vis d'une paire voisine, par soudure linéaire. Plate exchanger comprising a multiplicity of metal plates (10-15) juxtaposed and separated by intervals (A, B), one interval out of two (A) being intended for the circulation of a first fluid and the other intervals (B) being intended for the circulation of a second fluid substantially parallel to the first, each plate being connected at its periphery to the two adjacent plates in a sealed manner, so as to close, at least partially said intervals (A, B) while providing inlet and outlet ports for said fluids, said plates being assembled in pairs (10-11, 12-13, 14-15) by linear welding (16, 17) in two opposite end zones of the plates of each pair, characterized in that at least one plate (14) per pair comprises a wing (20), at least in one of said end zones and in the vicinity of said weld (16), folded substantially at right angles and connected in its zone marginal free to a facing plate (13) is from a neighboring pair, by linear welding.
