Abstract
A heat exchanger is provided for a gas turbine engine. This heat exchanger includes a pair of heat exchanger manifolds and a stack of flow channel modules arranged and fluidly coupled between the heat exchanger manifolds. The flow channel modules include a first flow channel module that includes a first heat exchanger section and a second heat exchanger section. The first heat exchanger section includes a base plate, a plurality of flow channel walls and a plurality of heat transfer augmentors. The flow channel walls project out from 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. The heat transfer augmentors project partially into at least one of the flow channels. A first of the heat transfer augmentors is formed from a different material than the base plate.
