Title (EN) MECHANICALLY ASSEMBLED HIGH INTERNAL PRESSURE HEAT EXCHANGER
(FR) ECHANGEUR DE CHALEUR FORME PAR ASSEMBLAGE MECANIQUE, A PRESSION INTERNE ELEVEE
Abstract: front page image
(EN)The present invention relates to mechanically assembled high internal pressure flat oval tube heat exchangers, where fin plates are provided with a special wavy configuration forming pattern of a zig-zag, sinuous or semicircular form or a combination of these forms. Preferably the waves are running in parallel in relation to the longest axis of the flat oval tube cross sections in a direction vertical to the tubes' longitudinal axis, thus increasing substantially the deformation pressure yield of the tubes.
(FR)La présente invention concerne des échangeurs de chaleur, à pression interne élevée, constitués de tubes ovales plats, assemblés mécaniquement, comprenant des ailettes présentant une configuration spéciale à ondulations, ces ondulations ayant une forme en zig-zag, sinusoïdale ou semi-circulaire, ou bien résultant d'une combinaison de ces trois types de formes. De préférence, ces ondulations sont parallèles au grand axe de la section transversale du tube ovale plat, dans le sens vertical par rapport à l'axe longitudinal des tubes, ce qui augmente nettement la résistance des tubes à la déformation due à la pression.
