Abstract

L'invention concerne un échangeur de chaleur à plaques (100) comprenant au moins un premier et un deuxième bloc d'échange thermique (10a, 10b). Chaque bloc d'échange thermique (10a, 10b) comprend plusieurs plaques séparatrices (4) parallèles, qui forment une pluralité de passages de transfert de chaleur (1) pour des fluides participant au transfert de chaleur. Les blocs d'échange thermique (10a, 10b) sont limités à l'extérieur par des plaques de recouvrement (5a, 5b). Une première plaque de recouvrement (5a) du premier bloc d'échange thermique (10a) est fixée à une deuxième plaque de recouvrement (5b) opposée du deuxième bloc d'échange thermique (10b). Selon l'invention, au moins un premier profilé allongé (11) est fixé à la première plaque de recouvrement (5a) et au moins un deuxième profilé (12) allongé et parallèle au(x) premier(s) profil(s) est fixé à la deuxième plaque de recouvrement (5b) de sorte que les deux profilés (11, 12) sont opposés l'un à l'autre dans une direction (R) parallèle aux plaques de recouvrement (5a, 5b). Un espace intermédiaire (15) est prévu entre les deux profilés, dans lequel un élément allongé (13) est relié par friction aux deux profilés (11, 12) de sorte que les deux plaques de recouvrement (5a, 5b) et donc les deux blocs d'échange thermique (10a, 10b) sont fixés l'une à l'autre, l'élément allongé (13) étant conçu comme un profilé creux. L'invention concerne par ailleurs un procédé correspondant.
