Abstract

La présente invention concerne des réservoirs de collecteur (2, 3) pour un échangeur thermique qui se composent de plaques (8, 31) pour former des sections de collecteur, de plaques (9, 32) destinées à raccorder des tuyaux, et de plaques intermédiaires (10, 33) interposées entre les plaques (8, 9, 31, 32). Des sections gonflées de façon externe (12A, 12B, 34A, 34B) sont formées sur les plaques (10, 33). Entre des sections adjacentes gonflées de façon externe (12A, 12B, 34A, 34B) sont formés des trous débouchants (28, 29, 30, 44, 45, 46) dans les trois plaques (8, 9, 10, 31, 32, 33), dans des positions où les trous sont alignés les uns avec les autres. Des brides (30a, 46a) sont formées de façon solidaire avec des bords périphériques des trous débouchants (30, 46) des plaques intermédiaires (10, 33). Les brides (30a, 46a) sont insérées dans les trous débouchants (18, 44) des plaques (8, 31) et leur diamètre est agrandi, et, en outre, des bords périphériques des trous débouchants (29, 45) des plaques (9, 32) sont en saillie jusqu'au côté des plaques (10, 33) pour être comprimés dans les trous débouchants (30, 46). En conséquence, les trois plaques (8, 9, 10, 31, 32, 33) sont serties et fixées au niveau des bords périphériques des trous débouchants (28, 29, 30, 44, 45, 46), et, dans cet état, les trois plaques sont alors brasées les unes aux autres. La résistance à la pression des réservoirs de collecteur est améliorée.
