Abstract

L'invention concerne un ventilateur d'échange de chaleur comportant une pluralité de rails de guidage (11) installés à l'intérieur d'un carter externe (5), entrant en prise avec un cadre (22) d'échangeur de chaleur et guidant la fixation d'un échangeur de chaleur (8) au carter externe (5) et sa séparation à partir de ce dernier, un filtre à air (12) disposé en aval de l'échangeur de chaleur (8) dans le passage d'alimentation en air dans le carter externe (5) afin d'éliminer les impuretés contenues dans l'écoulement d'alimentation en air, et une partie de support de filtre à air fixée à une première surface dans le carter externe (5) et destinée à porter le filtre à air (12). La partie de support de filtre à air est disposée, sur la première surface, au niveau d'une position faisant face à un rail de guidage aval, c'est-à-dire un rail de guidage entrant en prise avec un cadre (22) d'échangeur de chaleur fixé à un côté dans le carter externe (5) disposé du côté aval du circuit de ventilation d'alimentation en air. Le filtre à air (12) est porté entre la partie de support de filtre à air et le rail de guidage aval, étant en même temps en contact étroit avec la partie de support de filtre à air et le rail de guidage aval.
