FIELD: electric mechanical engineering, possible use for cooling electric generators and electric engines.
SUBSTANCE: in proposed system for cooling electric machines, containing compressed air source with force pipeline, splitting vortex pipe, having as a result of energy division to hollows - hot one and cold one, thermal pipe made inside the hollow shaft of electric machine, as a special feature, along axis of hollow shaft a tubular channel is made for passage of cold flow from splitting vortex pipe, and space, formed by external surface of tubular channel and internal surface of hollow shaft is thermal pipe, condensation area of which - external surface of tubular channel, and evaporation area - internal surface of hollow shaft.
EFFECT: efficient and even cooling of electric machine, simplified construction, increased manufacturability.
