Abstract

La présente invention concerne un échangeur de chaleur comprenant : une partie centrale comprenant une partie de réservoir d'entrée et une partie de réservoir de sortie dans laquelle un espace pour stocker et faire circuler de l'eau de refroidissement est formé, et une pluralité de tubes qui sont raccordés aux deux extrémités des parties de réservoir pour former des trajets d'écoulement d'eau de refroidissement, et comportant une rainure d'insertion d'élément d'étanchéité formée de façon concave sur une surface externe de celle-ci; et un élément d'étanchéité comprenant un corps ayant un côté inséré dans la rainure d'insertion d'élément d'étanchéité de la partie centrale, et un joint à lèvre s'étendant depuis le corps et faisant saillie depuis la surface externe du noyau. Ainsi, l'élément d'étanchéité est aisément couplé à la partie centrale, et lorsque la partie centrale est insérée et logée dans un boîtier, un espace entre la partie centrale et le boîtier est scellé au moyen de l'élément d'étanchéité pour empêcher l'air de passer entre le boîtier et la partie centrale, de sorte que l'efficacité d'échange de chaleur puisse être améliorée.
