Title
(EN) PLATE HEAT EXCHANGER
(FR) ECHANGEUR DE CHALEUR A PLAQUES
Abstract
(EN)
A plate heat exchanger, which comprises a plurality of plates (1) arranged to the side of each other, each plate consisting of two metal sheets (2, 3), which are welded one to the other along two parallel edges and have longitudinal bulgings in parallel with said edges. The invention has the object to produce a plate heat exchanger where the medium flowing within the plate is guided in a direction in parallel with the extension of the bulgings and back in the same direction. Each plate (1) is formed with a turning zone in that the bulgings in pairs meet in such a manner, that in the sheet plane two outermost bulgings meet along a semicircle line, thereafter the two bulgings next to the outermost ones, and so on, and the number of bulgings is an integer number.
(FR)
Un echangeur de chaleur a plaques comprend une pluralite de plaques (1) disposees les unes a cote des autres, chaque plaque consistant en deux feuilles metalliques (2, 3) qui sont soudees l"une a l"autre le long de deux bords paralleles et possedent des renflements longitudinaux paralleles auxdits bords. L"objet de l"invention est de produire un echangeur de chaleur a plaques ou le milieu s"ecoulant dans la plaque est guide dans une direction parallele a l"extension des renflements et effectue le retour dans la meme direction. Chaque plaque (1) est formee avec une zone tournante dans laquelle les renflements en paires se rencontrent de telle maniere que, dans le plan de la feuille, les deux renflements les plus a l"exterieur se rencontrent selon une ligne semi-circulaire, puis les deux bombements suivant les deux renflements les plus a externes etc., le nombre de renflements etant un nombre entier.
