Definitions

  • the chamber is configured to be leakproof with respect to the coil heads
  • the flange comprises a plurality of first and second orifices for an inlet or a cooling fluid outlet of the chamber, said openings opening on a peripheral face of the flange. So the room
  • the separating plate comprises notches allowing a circulation of the cooling fluid between an external cylindrical space located on the side of the outer part and an internal cylindrical space located on the side of the inner part. These notches allow both to regulate the flow of the cooling fluid in the chamber, as well as the pressure drops and to provide a cooling path bypassing the chamber.
  • the ring comprises radial projections delimiting a cavity and having at least one hole
  • the notches 32 of the separator plate 3 are offset angularly with respect to the first orifices 72 and the second orifices 74, in order to avoid disturbing the circulation of the cooling fluid passing through these orifices 72, 74.
  • This first embodiment is particularly suitable for electrical machines with individual winding, that is to say a winding comprising a winding around a single tooth of the plates 90 forming the stator 9.
  • each coil 106 comprises two coil heads 10, and the coil heads 10 are individual and adjacent to each other.
  • the internal part 4 thus comprises only the U-shaped section. 50, of T or I.
  • the ring 8 comprises projections 81 which extend radially towards the inside of the flange 1, that is to say which extend towards the center of the flange 1, here represented by the longitudinal axis L.
  • the internal part 4 has grooves 48 open on its inner face 44 and intended to receive the projections 81.
  • the inner part 4 comprises radial walls 47 on its inner face 44 forming a plurality of housings 43, as in the first embodiment of the flange 1.
  • the inner portion 4 provided with grooves 48 may comprise a single housing 43 circular, as in the second embodiment of the flange.
  • the second path allows the cooling fluid to bypass the chamber 5, that is to say not to enter the chamber 5, and to borrow 15 directly the flow of circulation formed between the fins 96 of the stator 9 passing by the notches 32 of the separator plate 3.
  • the cooling fluid present in the outer cylindrical space 62 passes into the internal cylindrical space 64 while circulating through the notches 32.
