Title (EN) A HEAT EXCHANGER COMPRISING PLATE ELEMENTS WITH SPIRAL DUCTS
(FR) ECHANGEUR DE CHALEUR COMPRENANT DES ELEMENTS DE PLAQUE MUNIS DE CONDUITS SPIRALES
Abstract: front page image
(EN)The invention relates to a heat exchanger consisting of plate elements which are provided with a profile and arranged such that the profile produces spaced ducts or layers of ducts through which one or more fluids are conveyed. The plate elements (1) comprise at least two parts (2, 3), which have a plurality of substantially longitudinally extending grooves (4) provided with spiral profiles (5), so that the grooves together form tubular ducts (6) with spiral profiles. Spaced flow paths are achieved hereby, so that two or more fluids may be conveyed in these without getting into direct contact with each other. It is also ensured that the ducts may be made with different cross-sectional areas and geometry, thereby allowing the flow characteristics to be optimized individually.
(FR)L'invention concerne un échangeur de chaleur constitué d'éléments de plaque dont le profil et l'agencement permettent de définir des couches de conduits ou des conduits espacés à travers lesquels un ou plusieurs fluides sont acheminés. Ces éléments de plaque (1) comprennent au moins deux parties (2, 3) munies d'une pluralité de rainures sensiblement longitudinales (4), ces rainures présentant des profils spiralés (5) et définissant ensemble des conduits tubulaires (6) dotés de profils spiralés. On obtient ainsi des voies d'écoulement espacées, au moins deux fluides pouvant être acheminés dans ces voies sans venir directement au contact l'un de l'autre. Ce système permet également d'obtenir des conduits dont la géométrie et les zones transversales diffèrent, d'où la possibilité d'optimiser les caractéristiques d'écoulement de manière individuelle.
