Le collecteur (80) de l'échangeur de chaleur comprend un premier élément (40) dans lequel sont formés des trous d'insertion servant à insérer les tubes de transfert de chaleur (60), et une première rainure d'installation d'élément d'étanchéité formée autour des trous d'insertion et dans laquelle un premier élément d'étanchéité est ajusté par pression entre la première rainure d'installation d'élément d'étanchéité et les tubes de transfert de chaleur (60), et un second élément (50) dans lequel sont formés une partie de rainure (23c) pour former les orifices de raccordement (21, 22) et le trajet d'écoulement, et une cavité de stockage (30a) pour stocker le premier élément (40). Des parties à large diamètre (60b) destinées à empêcher le premier élément d'étanchéité de tomber sont formées aux extrémités des tubes de transfert de chaleur (60) insérés dans les trous d'insertion.
