1. A heat exchanger for a gas turbine engine, comprising:
a first heat exchanger manifold;
a second heat exchanger manifold; and
a stack of flow channel modules arranged and fluidly coupled between the first heat exchanger manifold and the second heat exchanger manifold, the flow channel modules comprising a first flow channel module that includes a first heat exchanger section and a second heat exchanger section;
the first heat exchanger section including a base plate, a plurality of first fins, a plurality of flow channel walls and a plurality of heat transfer augmentors;
the first fins projecting out from a first side of the base plate;
the flow channel walls projecting out from a second side of the base plate, which is opposite the first side of the base plate, to the second heat exchanger section thereby forming a plurality of flow channels between the first heat exchanger section and the second heat exchanger section; and
the heat transfer augmentors projecting out from the second side of the base plate partially into at least one of the flow channels;
wherein a first of the heat transfer augmentors is formed from a different material than the base plate;
wherein a first of the first fins overlaps a first of the flow channel walls at an intermediate location along the base plate;
wherein the base plate has a vertical thickness measured vertically from the first side of the base plate to the second side of the base plate at the intermediate location;
wherein the first of the first fins has a vertical height measured vertically from the first side of the base plate to a distal end of the first of the first fins at the intermediate location; and
wherein the vertical thickness is greater than the vertical height.
