Abstract

L'invention concerne un échangeur de chaleur permettant l'échange de chaleur entre un fluide extérieur s'écoulant à l'extérieur et un milieu de chaleur, comprenant : une partie centrale (4) formée en empilant une pluralité de tubes (9) canalisant le milieu de chaleur ; et un réservoir de distribution (2, 3) raccordé à au moins une partie d'extrémité des tubes, le réservoir de distribution (2, 3) collectant ou distribuant le milieu de chaleur. Le réservoir de distribution comprend un premier élément de cloison (52) permettant de diviser l'espace interne du réservoir de distribution en deux dans la direction longitudinale des tubes en un premier espace (17A) et un second espace (17B) ; et un second élément de cloison (54) permettant de diviser le premier espace et/ou le second espace en deux dans la direction dans laquelle les tubes sont empilés. Le second élément de cloison est intercalé par le réservoir de distribution (2, 3) et/ou le premier élément de cloison (52) depuis les deux côtés par rapport à la direction dans laquelle les tubes (9) sont empilés.
