La structure de raccordement de tube de réfrigérant en aluminium selon la présente invention comprend : un corps de raccordement, qui est un corps de tube ayant un trou traversant formé au centre de façon à pénétrer dans celui-ci dans la direction longitudinale, qui a une partie boulon formée sur la surface externe de celui-ci, et qui a une surface de pressurisation interne formée sous une forme effilée, le diamètre externe de la surface de pressurisation interne diminuant graduellement à partir de l'avant de la partie boulon vers l'extrémité avant ; un dispositif de fixation, qui est un corps de tube ayant un trou traversant formé au centre de façon à pénétrer dans celui-ci dans la direction longitudinale, une partie écrou étant formée sur la surface interne du dispositif de fixation, et couplée par vissage à la partie boulon du corps de raccordement, et une surface de pressurisation externe étant formée sous une forme effilée, le diamètre interne de la surface de pressurisation externe diminuant graduellement à partir de l'avant de la partie écrou vers l'avant de façon à correspondre à la surface de pressurisation interne du corps de raccordement ; un tube de réfrigérant en aluminium ayant une partie d'extension de tube formée sous une forme effilée, le diamètre de la partie d'extension de tube augmentant vers une extrémité, de telle sorte que celle-ci est disposée entre la surface de pressurisation interne et la surface de pressurisation externe ; un manchon interne ayant une surface externe insérée dans une entrée d'extrémité du tube de réfrigérant en aluminium de façon à venir en contact avec la surface interne du tube de réfrigérant en aluminium, une partie joint d'étanchéité interne étant formée sur une partie d'extrémité d'un côté de celui-ci et s'étendant de façon à correspondre à la partie d'extension de tube du tube de réfrigérant en aluminium ; et un manchon externe, dans lequel la partie d'extrémité du tube de réfrigérant en aluminium est insérée, de telle sorte que la surface interne du manchon externe vient en contact avec la surface externe du tube de réfrigérant en aluminium, une partie joint d'étanchéité externe étant formée sur une partie d'extrémité du manchon externe et s'étendant de façon à correspondre à la partie d'extension de tube du tube de réfrigérant en aluminium. La partie d'extension de tube du tube de réfrigérant en aluminium est formée de façon à avoir une première partie d'extension de tube, qui est formée de façon à être inclinée selon un premier angle d'inclinaison par rapport à la direction longitudinale, et une seconde partie d'extension de tube, qui s'étend à partir de la première partie d'extension de tube, et qui est formée de façon à être inclinée selon un second angle d'inclinaison qui est supérieur au premier angle d'inclinaison. La partie joint d'étanchéité interne du manchon interne est formée de façon à avoir des première et seconde parties joint d'étanchéité correspondant aux première et seconde parties d'extension de tube du tube de réfrigérant en aluminium. Après qu'une extrémité du tube de réfrigérant en aluminium a été insérée dans le manchon externe, et après que le manchon interne a été inséré dans l'extrémité du tube de réfrigérant en aluminium, la partie écrou du dispositif de fixation et la partie boulon du corps de raccordement sont fixées par vissage, de telle sorte que la surface de pressurisation interne du corps de raccordement vient en contact avec la surface interne de la partie joint d'étanchéité du manchon interne, et de telle sorte que la surface de pressurisation externe du dispositif de fixation vient en contact avec la surface externe de la partie joint d'étanchéité du manchon externe.
