  • Heat exchanger with stacked flow channel modules
    Patent number: 11835304
    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.

  • MANUFACTURING A HEAT EXCHANGER USING A MATERIAL BUILDUP PROCESS
    Publication number: 20210071962
    Abstract: A method is provided for manufacturing at least a portion of a heat exchanger. During this method, a first heat exchanger section is formed that includes a base and a plurality of protrusions. The forming of the first heat exchanger section includes building up at least one protrusion material on the base to form the protrusions. The first heat exchanger section is attached to a second heat exchanger section. A plurality of flow channels are defined between the first heat exchanger section and the second heat exchanger section.
