Abstract

ÉCHANGEUR THERMIQUE à DÉFLECTION L’invention concerne un échangeur de chaleur (10) comportant un premier et un deuxième étages (E1, E2) séparés par une plaque transversale (20), chaque étage permettant la mise en circulation d’un fluide (14, 16), configuré pour que le premier et le deuxième fluide (14, 16) se croisent dans une zone d’échange (12), l’un des étage comportant, en amont de la zone d’échange, une zone de distribution (24) qui comporte une zone de déflection (27). La zone de distribution présente trois parties distinctes (A, B, C) : - une première partie (A), située en amont du point de déflection, comportant deux ailettes à direction constante, - une seconde partie (B), située à l’endroit de la zone de déflection (27) des fluides (14, 16), comportant deux déflecteurs principaux (28) présentant un angle de déflection (β), - une troisième partie (C) comportant deux déflecteurs principaux (28) et deux déflecteurs secondaires (30) intercalés entre eux.
