Abstract
The invention relates to a heat exchanger (16) between a fluid and an air flow (FS), the heat exchanger comprising a heat exchange wall (17) separating the fluid and the air flow (FS), the heat exchange wall (17) having a heat exchange surface (18) extending parallel to the longitudinal direction (AX) of the air flow (FS), the air flow (FS) being in contact with the heat exchange surface. According to the invention, the heat exchange wall (17) comprises at least one turbulence generator (22) extending in a recessed manner relative to the heat exchange surface (18).
