Abstract

L’invention propose un échangeur thermique pour véhicule automobile, comprenant une pluralité de tubes 1 à l’intérieur desquels un premier fluide est apte à circuler, chaque tube 1 étant plat et doté d’une ailette 3 interne s’étendant à l’intérieur du tube 1 et étant pliée de façon à former un crénelage composé d’une succession de cloisons latérales 3a et de sommets 3b, lesdits sommets 3b étant en contact avec les parois transversales 2a, 2b du tube 1, ladite ailette 3 interne définissant une pluralité de canaux 4, chaque cloison latérale 3a s’étendant le long de l’axe X et séparant deux canaux 4 adjacents. Cet échangeur se caractérise en ce que lesdites cloisons latérales 3a sont pourvues de moyens d’augmentation du coefficient de transfert thermique consistant en des bossages 5.
