Hot air exhaust device for a jet engine air intake fairing with de-icing circuit

The air intake cowling (9) for a jet engine, whose leading edge (16) is hollow and traversed by a hot air flow for de-icing (17), comprises outlets for the hot air flow to the outside of said leading edge (16), which form an arrangement (18) such that at least two jets of hot pressurized air passing through two adjacent orifices present, downstream of a calibrating piece (23) in which said orifices are formed, different inclinations with respect to said calibrating piece.
