Abstract

L'invention porte sur un échangeur de chaleur extérieur (5), dans au moins trois rangées, lequel échangeur comprend un échangeur de chaleur principal (8) et un sous-échangeur de chaleur (9). Par la constitution d'une extrémité de l'échangeur de chaleur principal (8) et du sous-échangeur de chaleur (9) par des plaques d'extrémité séparées (10a, 10b), il devient inutile de supporter l'échangeur de chaleur extérieur (5) d'un seul tenant en trois rangées à l'aide d'un ensemble, ou analogues. Par conséquent, à l'extrémité non reliée aux plaques d'extrémité, la chute d'une ailette (20) d'une rangée d'échangeurs de chaleur qui constitue le centre de trois rangées est évitée, cette chute étant provoquée par le fait que l'ailette (20) est soumise à une force de pression à partir de rangées d'échangeurs de chaleur aux deux extrémités, et une fonctionnalité de soufflage est améliorée.
