Abstract

La présente invention concerne un échangeur de chaleur brasé à plaques (100) comprenant plusieurs plaques d'échange de chaleur (120, 130, 140, 150) empilées et présentant un motif de nervures (R) et de rainures (G) réalisé par pressage et conçu pour maintenir les plaques d'échange de chaleur (120, 130, 140, 150) dans la pile à une certaine distance les unes des autres par croisement de points entre les nervures (R) et les rainures (G) de plaques voisines. Il se forme ainsi des canaux d'écoulement entre les plaques, lesdits canaux d'écoulement étant en communication fluidique sélective avec des ouvertures d'orifices (A, B, C, D) de sorte que des fluides d'échange de chaleur peuvent s'écouler d'une ouverture d'orifice à une autre par les canaux d'écoulement entre les plaques sous échange de chaleur avec un fluide s'écoulant par un canal d'écoulement entre plaques voisin. L'échangeur de chaleur à plaques comprend en outre une plaque d'extrémité (110) qui est pourvue d'au moins une rainure de renfort (111 ; 112 ; 113). Ladite rainure de renfort (111 ; 112 ; 113) est une rainure réalisée par pressage dans la plaque d'extrémité, ladite rainure de renfort (111 ; 112 ; 113) étant orientée vers la plaque d'échange de chaleur voisine (120) et un motif de renfort (121 ; 122) conçu pour loger ladite rainure de renfort (111 ; 112 ; 113) de la plaque d'extrémité (110) étant agencé dans la plaque d'échange de chaleur (120) voisine de la plaque d'extrémité (110).
