Abstract

L’invention concerne une machine électrique tournante (10) comprenant : un rotor (12) mobile en rotation autour d’un axe (X),un stator (11) disposé autour du rotor (12), etune chambre (31) de refroidissement annulaire de longueur axiale (lcr) et de hauteur radiale (hcr), disposée radialement autour du stator (12), délimitée entre une paroi radialement intérieure (70) et une paroi radialement extérieure (71) et dans laquelle s’écoule dans une direction circonférentielle un fluide de refroidissement, l’une au moins de la paroi radialement intérieure et extérieure (70, 71) comprenant une pluralité d’ailettes de refroidissement (38) s’étendant dans la direction circonférentielle, dans laquelle des ailettes de refroidissement (38) portent une pluralité de reliefs (73) faisant saillie en direction d’une autre ailette de refroidissement (38) sans atteindre cette dernière.
