Abstract

L'invention concerne un échangeur de chaleur gaz-liquide (20) pour un conduit d'écoulement (16) de gaz dans une turbomachine. L'échangeur (20) comprend une partie aval (23). La partie aval (23) comprend des étages (22) comprenant chacun au moins un passage d'écoulement du gaz (30) et au moins un passage d'écoulement de liquide (46). Au moins certains des passages d'écoulement du gaz (30) et/ou de liquide (46) participent à la délimitation d'une surface externe aval (S2) qui délimite l'échangeur (20, 220) vers l'aval et qui est destinée à être en contact du gaz s'écoulant dans le conduit (16). Les étages (22) étant de longueurs (l1, l2) variables vers l'aval, de sorte que la surface externe aval (S2) est au moins partiellement aérodynamique.The invention relates to a gas-liquid heat exchanger (20) for a gas flow duct (16) in a turbomachine. The exchanger (20) includes a downstream part (23). The downstream part (23) comprises stages (22) each comprising at least one gas flow passage (30) and at least one liquid flow passage (46). At least some of the gas (30) and / or liquid (46) flow passages participate in the delimitation of a downstream external surface (S2) which delimits the exchanger (20, 220) downstream and which is intended to be in contact with the gas flowing in the conduit (16). The stages (22) being of lengths (11, 12) variable downstream, so that the downstream external surface (S2) is at least partially aerodynamic.
