- each heat exchange device can also be arranged in a blade 28 of the rectifier.
- the heat is conducted by the material constituting the blade 28 from the internal fluid to the air flow.
- an aerodynamic element of the turbomachine by designating it as being a blade. It will be understood that this designation concerns both any casing arm, or any other stationary vane, which includes a heat exchange device. The description of each other blade comprising such a heat exchange device will be deduced by similarity from this description which follows.

- the circulation duct 46 surrounds the accumulator 44 of the heat pipe 39. It will be understood that the invention is not limited to this embodiment and that any other embodiment allowing heat exchange between the accumulator 44 and the circulation conduit 46 can be considered. For example, the accumulator 44 and the circulation conduit 46 are entangled.

- the cooling circuit may comprise a single blade 28 provided with a heat pipe or else several blades 28 which are distributed around the main axis of the turbomachine.
- blades 28 can thus be arranged in the turbomachine with their main radial axis which is oriented substantially vertically according to the earth's gravity with the foot 34 located vertically under the body 32 or with their axis inclined relative to the vertical direction with the foot 34 located above the body 32.
- the geometries of the various cavities of these non-vertical heat pipes can be optimized according to their inclinations to facilitate the circulation of the condensates.

These vanes 28 are preferably the blades located above a horizontal median plane of the turbine engine 10, so that the earth's gravity promotes the flow of the working fluid in the heat pipe
- the blade 28 shown is intended to be located below the horizontal median plane of the turbine engine 10.
- This blade 28 has an external radial head end 60 which is connected to the external stator of the turbomachine.
