Novel ventilating structure of power generator of distribution shaft extension through-flow turbine

The utility model relates to a novel ventilating structure of a power generator of a distribution shaft extension through-flow turbine. The novel ventilating structure comprises a machine set body, wherein a rotor, a stator and an end shield are arranged inside the machine set body; two groups of air coolers are arranged above the machine set body; a middle air duct is formed between the two groups of air coolers; two outer air ducts are formed at the outer sides of the two groups of air coolers; the stator and the end shield are in an integral molding structure; and the air coolers are in a sheet-punching expansion joint type. In the novel ventilating structure, the air coolers are arranged above the machine set, a bran-new ventilating duct is designed, hot air coming out of the stator enters the left air cooler and the right air cooler respectively through the middle air duct; after the hot air is cooled, the cooled air enters the rotor along the two outer air ducts, blows the rotor and enters the stator so
