Abstract

L’invention concerne un échangeur de chaleur (10) pour une turbomachine, présentant un premier axe (X), l’échangeur de chaleur étant destiné à réaliser un échange thermique entre deux fluides, l’échangeur de chaleur comprenant un corps formant une enceinte à l’intérieur duquel sont agencés une première série de premiers tubes creux et une deuxième série de deuxièmes tubes creux qui s’étendent parallèlement suivant au premier axe, les premier et deuxième tubes comprenant chacun une première extrémité débouchant dans une zone de retour. Selon l’invention, l’échangeur de chaleur comprend une troisième série de troisièmes tubes (25) agencés dans la zone de retour et reliant les premières extrémités des premiers tubes et des deuxièmes tubes, chaque troisième tube étant venu de matière avec un premier tube et un deuxième tube, et en ce que les troisièmes tubes (25) forment des motifs prédéterminés de manière à présenter au plus deux longueurs (L, L1, L2) prédéterminées.
