Title
(EN) ARRANGEMENT AT PLATE HEAT EXCHANGER
(FR) DISPOSITION D"UN ECHANGEUR DE CHALEUR A PLAQUES
Abstract
(EN)
A plate heat exchanger, which comprises a plurality of plates located to the side of each other and consisting each of two sheets facing toward each other, which sheets are formed with longitudinal valleys, which facing toward each other form passages between the sheets when the sheets abut each other. The object of the invention is to provide a plate heat exchanger with straight unobstructed passages in order to reduce the problem of clogging and to facilitate cleaning. Between adjacent passages there must be free flow so that washing can be carried out even when a single passage should have been clogged. A further advantage is that the sheets can be formed in press tools without risk of fracture indications to arise. The invention implies that the valleys (5) are formed with grooves (19) transverse to the longitudinal direction of the valley and extending continuously from one outermost located valley to the other outermost located valley.
(FR)
Un echangeur de chaleur a plaques comprend une pluralite de plaques situees les unes a cote des autres et consistant chacune en deux feuilles disposees l"une en face de l"autre, ces feuilles etant formees avec des vallees longitudinales qui, lorsqu"elles sont face-a-face, forment des passages entre les feuilles lorsque celles-ci sont accolees. L"objet de l"invention est de produire un echangeur de chaleur a plaques avec des passages droits non obstrues en vue de diminuer les difficultes de colmatage et de faciliter le nettoyage. Entre les passages adjacents il doit y avoir un ecoulement libre de maniere a pouvoir permettre le lavage meme si un seul passage est colmate. Un autre avantage est que les feuilles peuvent etre formees a la presse sans risque de rupture. L"invention implique que les vallees (5) soient formees avec des rainures (19) transversales par rapport aux vallees et s"etendant de maniere continue d"une vallee situee le plus a l"exterieur a l"autre vallee situee le plus a l"exterieur.
