A surface type air to oil cooler enables oil to flow from an inlet and down a first pass of an oil passageway. A first bypass, before the end of the first pass, allows oil to flow from the first pass to a second pass of the oil passageway. A second bypass may exist toward the end of the second pass to allow the oil to flow from the second pass to an outlet before the end of the second pass.

A heat exchange system for a turbomachine includes a heat exchanger that has a support wall extending along a longitudinal direction L and a plurality of fins each extending along a radial direction from a radially external surface of the support wall. The heat exchanger further includes a first profiled wall arranged upstream from the fins and configured to guide and slow down the flow of air entering the heat exchanger through the fins. A second profiled wall is arranged downstream from the fins and configured to accelerate the flow of air leaving the heat exchanger. Each first and second profiled wall is attached to the support wall via support elements extending radially from the radially external surface.
