1. An aircraft propulsion assembly comprising:
an engine;
a nacelle positioned around the engine;
an annular duct, which is defined by the engine and the nacelle, in which a bypass flow of cold air can flow;
at least one bifurcation connecting the engine and the nacelle, wherein the at least one bifurcation has:
a leading edge; and
a primary structure of a pylon housed in the at least one bifurcation, wherein the pylon is configured to connect the engine to an aircraft wing; and
at least one heat exchange device, which comprises:
a heat exchanger comprising a first hot air circuit connecting a first inlet and a first outlet, and comprising a second cold air circuit connecting a second inlet and a second outlet;
a hot air supply duct connected to the first inlet and configured to take hot air from the engine;
a hot air outlet duct connected to the first outlet and configured to convey hot air towards at least one item of aircraft equipment;
a cold air supply duct connected to the second inlet and configured to take cold air from the bypass flow; and
an exhaust duct connected to the second outlet and configured to expel the air out of the aircraft;
wherein the heat exchanger is a plate heat exchanger, having a hexagonal longitudinal section and positioned in the bifurcation.
