- the flow air Fx is likely to be generated by blowing as in the schemes (m) to (o) illustrates.
- the air flow Fx is pushed by the propeller 5 to the heat exchanger or exchangers, the propeller 5 being disposed in front of the exchangers.
- the air flow Fx is likely to be generated by suction.
- the air flow Fx is sucked by the propeller 5 through the heat exchanger or exchangers, the propeller 5 being disposed after the heat exchangers, in particular between these and the equipment 1 .
- Diagrams (c), (d) and (e) of FIG. 11 respectively illustrate various examples of arrangement of the hydraulic circuit 31a, 31b and 31c formed inside the stator 7a.
- At least one first annular channel 50a extends at least partly along the ring 50.
- the component or components 50, 51 and / or 52b stator 7a are individually or collectively arranged in double shells assembled axially with each other, particularly by sealing.
- the radiator or radiators 8a, 8b, or even the condenser 8c are successively arranged one after the other in the direction of movement of the air flow Fx, in particular parallel to their general plane.
- the flow of air Fx generated by the motor-fan unit 3 passes successively through the condenser 8c if present, the radiator appendix 8b at low temperatures if it is present, then the main radiator 8a, said high temperatures.
- the flow of air Fx is likely to be generated by blowing as in the diagrams (f) to (h) illustrates. In this embodiment, the air flow Fx is pushed by the propeller 5 to the heat exchanger or exchangers, the propeller 5 being disposed in front of the exchangers.
