Abstract

L’invention concerne un échangeur de chaleur pour une turbomachine d’aéronef, cet échangeur comportant deux plaques planes parallèles, respectivement supérieure et inférieure , ainsi que des ailettes (12) s’étendant entre les plaques et perpendiculairement à celles-ci, les ailettes (12) ayant une forme générale plane et parallèle à une direction d’un flux de gaz (F) destiné à s’écouler entre les plaques, les ailettes (12) comportant chacune des bords d’attaque (13) et de fuite (14) du flux de gaz (F) qui s’étendent perpendiculairement aux plaques. Selon l’invention, les bords d’attaque (13) et de fuite (14) sont en dents de scie. L’invention concerne aussi une turbomachine d’aéronef comprenant un tel échangeur. Figure pour l'abrégé : Figure 2
