Abstract

La présente invention concerne une unité d'échange thermique pour véhicules automobiles, comprenant un premier échangeur thermique qui présente deux tubes accumulateurs espacés entre eux et sensiblement parallèles, qui sont reliés par une pluralité de tubes de liaison parallèles entre eux et espacés dans la direction longitudinale des tubes collecteurs. Selon l'invention, les tubes de liaison débouchent, vis-à-vis de la largeur du fond de tube, mesurée perpendiculairement à l'axe longitudinal du premier tube collecteur, de façon asymétrique dans le premier tube collecteur, et la seconde partie de paroi a une section considérée perpendiculairement à l'axe du tube collecteur, qui augmente sur son côté qui rejoint la seconde zone d'extrémité du fond de tube, en s'éloignant de la première extrémité du fond de tube, dans une direction perpendiculaire à l'axe longitudinal des tubes de liaison et perpendiculaire à l'axe longitudinal du tube collecteur.
