Abstract

Abstract Translated from French On décrit un dispositif d'échange thermique - (17) dont la zone d'échange est constituée d'un empilement de plaques perforées (1,2) présentant des perforations disposées de telle façon que la superposition des perforations crée des espaces de circulation pour au moins deux fluides à des températures différentes, lesdites plaques perforées étant séparées deux à deux par au moins un joint - (7) disposé de manière que chaque perforation des plaques correspondant à un espace de circulation parcouru par un fluide soit séparé des perforations correspondant aux espaces de circulation parcourus par un fluide différent, ledit empilement étant maintenu sous une pression de serrage de 2 à 50 bars à l'aide d'une pluralité de tirants le traversant et ledit joint étant constitué par un graphite expanse fabriqué dans des conditions telles qu'il présente une masse volumique apparente d'environ 200 à 500 kg.<sub>m</sub>-<sub>3</sub>. A heat exchange device - (17) is described, the exchange zone of which consists of a stack of perforated plates (1,2) having perforations arranged in such a way that the superposition of the perforations creates circulation spaces for at least two fluids at different temperatures, said perforated plates being separated in pairs by at least one seal - (7) arranged so that each perforation of the plates corresponding to a circulation space traversed by a fluid is separated from the perforations corresponding to the circulation spaces traversed by a different fluid, said stack being maintained under a clamping pressure of 2 to 50 bars by means of a plurality of tie rods passing therethrough and said seal being constituted by an expanded graphite manufactured under conditions such as 'it has a bulk density of about 200 to 500 kg. <sub> m </sub> - <sub> 3 </sub>.
