Abstract

La présente invention concerne une machine électrique (1) tournante comprenant un rotor (7), un stator (6) et un dispositif de refroidissement. Le dispositif de refroidissement comprend un canal (8) de circulation d'un liquide caloporteur. Le canal comprend des zones sensiblement circonférentielles, dans lesquelles le canal (8) est subdivisé en plusieurs passages (13). Le canal comprend en outre des zones sensiblement hélicoïdales (12), dans lesquelles le canal (8) n'est pas subdivisé.The present invention relates to a rotary electrical machine (1) comprising a rotor (7), a stator (6) and a cooling device. The cooling device comprises a channel (8) for circulation of a heat transfer liquid. The channel comprises substantially circumferential zones, in which the channel (8) is subdivided into several passages (13). The channel further comprises substantially helical zones (12), in which the channel (8) is not subdivided.
