HEAT EXCHANGER

Abstract: a turbofan gas turbine engine comprises, in axial flow sequence, a heat exchanger module, a fan assembly, a compressor module, a turbine module, and an exhaust module. the fan assembly comprises a plurality of fan blades defining a fan diameter (d). the heat exchanger module is in fluid communication with the fan assembly by an inlet duct, and the heat exchanger module comprises a plurality of radially-extending hollow vanes arranged in a circumferential array with a channel extending axially between each pair of adjacent hollow vanes. the heat exchanger module has a square axial cross-sectional profile, where a side length of the square cross-section is d.
