Claim 0:
1. A heat exchange system of a turbomachine, the heat exchange system comprising: a heat exchanger comprising a support wall, a plurality of fins each extending in a radial direction from a radially outer surface of the support wall and configured to be swept by an air flow, and a cover covering the fins, wherein the cover is connected upstream, in a direction of flow of the air flow, to a first profiled wall and downstream to a second profiled wall,
wherein the first profiled wall is arranged upstream from the plurality of fins and configured so as to guide and slow down the air flow entering the heat exchanger through the plurality of fins, the first profiled wall comprising a first wall portion forming, with the support wall, an air inlet having a first radial height, said first height being less than a radial height of the fins
wherein the second profiled wall is arranged downstream of the plurality of fins and configured to accelerate the air flow exiting the heat exchanger,
wherein the cover has an at least partly curvilinear aerodynamic profile and an outer peripheral surface having surface continuity with radially outer surfaces of the first and second walls.
