HEAT EXCHANGER(S) FOR RECOVERING WATER AND/OR HEAT ENERGY FROM TURBINE ENGINE COMBUSTION PRODUCTS

A turbine engine (20) with an axis (22) includes a fan section (28), a turbine engine core (34), a bypass flowpath (46; 56), an engine housing (36), an evaporator (112), a condenser (113) and a core flowpath (62). The turbine engine core (34) is configured to power the fan section (28). The turbine engine core (34) includes a core compressor section (30), a core combustor section (31) and a core turbine section (32). The bypass flowpath (46; 56) is fluidly coupled with and downstream of the fan section (28). The engine housing (36) includes a cavity (152) radially outboard of and axially overlapping the fan section (28) and/or the bypass flowpath (46; 56). The evaporator module (112) is within the cavity (152). The condenser module (113) is within the cavity (152). The core flowpath (62) extends sequentially through the core compressor section (30), the core combustor section (31), the core turbine section (32), the evaporator module (112) and the condenser module (113).
