1. A gas turbine engine comprising:
a fan located at a forward portion of the gas turbine engine;
a compressor section and a turbine section arranged in serial flow order, the compressor section and the turbine section together defining a core airflow path;
a rotary member rotatable with at least a portion of the compressor section and with at least a portion of the turbine section; and
an outlet guide vane assembly comprising multiple outlet guide vanes located in an exhaust airflow path downstream of the turbine section, the multiple outlet guide vanes being spaced-apart circumferentially from each other over an angular range of about 360 degrees, and each multiple outlet guide vane defining a radial extent;
wherein at least one of the multiple outlet guide vanes comprises a cold fluid passageway extending at least partially radially therethrough through which a fluid coolant flows away from a thermal transport bus connected to a source of the liquid coolant and another of the multiple guide vanes comprises a heated fluid passageway extending at least partially radially therethrough through which the fluid coolant flows and receives heat from exhaust airflow from the core airflow path and returns to the thermal transport bus, the cold fluid passageway and heated fluid passageway are connected together forming a closed fluid passageway through the cold fluid passageway, away from the thermal transport bus and through the heated fluid passageway back to the thermal transport bus.
