  • the pre-fixing sleeve 222 ' is soldered together with the cover 207 and the terminal 210, for which it is prepared accordingly, so that it additionally stiffened the connection point lid-connection in the finished soldered state of the heat exchanger.
  • the prefixing of the connection 210 on the cover 207 takes place by means of gluing, ie a suitable adhesive is introduced between the connection 210 and the cover 207, possibly also only in one or more small subregions , which ensures sufficient pre-fixing.
  • the adhesive evaporates or hardens further - depending on the adhesive used - and the connection is securely fixed to the cover.
  • relatively large contact surfaces between the terminal and cover are provided, since the shape of the contact surface of the terminal 210 is adapted to the shape of the outside of the lid 207, which is formed at least partially curved in the region of the contact surface to the terminal 210.
  • connection and cover positively fix together, so that in the context of the (further) assembly and in the soldering oven no slipping the components to each other.
  • the contact surfaces of the terminals are formed according to the outer contours of the lid and possibly the bottom, so that no further processing of the moldings takes place. Due to the shape of the molded parts, the contact surfaces in the case of the embodiments described with reference to single-row gas cooler double-curved, in this case by two different, skewed axes, the curvature does not necessarily have to be cylindrical, while the contact surfaces in the case of described with reference to the double-row gas cooler described embodiments are simply curved. In addition to the curvatures are also flat surfaces, possibly also edges, in particular between curved and flat surfaces, provided.

Abstract

La présente invention concerne un échangeur thermique, en particulier un refroidisseur à gaz, comprenant au moins un dispositif d'accumulation et/ou de répartition (4; 104) et au moins un dispositif d'écoulement le dispositif d'accumulation et/ou de répartition (4; 104) présentant au moins deux voies de circulation destinées à un fluide, et étant formé par au moins deux pièces moulées (5; 105), au moins une ouverture d'entrée ou de sortie (8; 108) destinée au fluide, étant pratiquée dans au moins l'une des pièces moulées (5; 105), et un élément de raccord (10; 110; 210) étant mis en place sur la pièce moulée (5; 105), ledit élément de raccord étant appliqué de façon étanche à la surface du côté extérieur de la pièce moulée (5; 105). Selon l'invention, la forme de la surface d'appui de l'élément de raccord (10; 110; 210), est adaptée à celle du côté extérieur de la pièce moulée (5; 105) qui présente au niveau de la surface d'appui sur l'élément de raccord (10; 110; 210), au moins par zones, une double courbure.
