Abstract

La présente invention concerne un échangeur de chaleur (13), qui est lourd, et est soutenu par un premier châssis (17). Le premier châssis (17) permettant de soutenir l'échangeur de chaleur (13) est fixé à une paroi du côté installation (45) sans utiliser un second châssis (27). Le premier châssis (17) est configuré par la formation de façon solidaire d'une partie support d'échangeur de chaleur (17h) permettant de soutenir l'échangeur de chaleur (13), qui est lourd, avec une partie de montage devant être fixée directement à la paroi du côté installation (45). Il en résulte que, comparativement à un cas dans lequel un châssis permettant de soutenir un objet lourd et un châssis permettant une fixation à la paroi du côté installation (45) sont formés séparément, il est possible d'éliminer la fragilité d'une section raccord permettant de raccorder les châssis séparés, et d'augmenter la résistance du premier châssis (17).
