Abstract

L'invention concerne un échangeur de chaleur en plaque comprenant un corps avec des parois cylindriques, des collecteurs d'admission et d'évacuation de milieux d'échange de chaleur, et une buse disposée dans le corps et se présentant sous forme d'un ensemble de plaques/films gaufrées ou lisses courbées dans la direction radiale en spirale, disposées en couches et définissant des canaux longitudinaux alternants pour le passage dans des directions opposées de milieux d'échange de chaleur, et sur les extrémité d'entrée et de sortie desquelles sont disposés des inserts-réducteurs d'extrémité qui chevauchent partiellement les canaux afin de former des sections d'entrée et de sortie communiquant avec les collecteurs correspondants d'admission et d'évacuation de milieux d'échange de chaleur ; les sections d'entrée des canaux sont disposées sur les côtés opposés du corps. Les extrémités d'entrée des canaux comportent des inserts-réducteurs d'extrémités qui chevauchent partiellement les canaux dans la zone centrale du corps tandis que les extrémités de sortie des canaux comportent respectivement des inserts-réducteurs qui chevauchent partiellement les canaux depuis les côtés opposés dans la zone périphérique du corps.
