Air-to-air cooling double-fed asynchronous wind driven generator

Abstract

The invention relates to an air-to-air cooling double-fed asynchronous wind driven generator, in particular relates to an air-to-air cooling double-fed asynchronous wind driven generator with a good heat radiation effect. With the adoption of the air-to-air cooling double-fed asynchronous wind driven generator disclosed by the invention, the problem that the conventional double-fed asynchronous wind driven generator has poor ventilation and a heat radiation effect of a motor due to an unreasonable structure can be solved. The air-to-air cooling double-fed asynchronous wind driven generator comprises an engine seat, a rotating shaft, a stator, a rotor and an air-to-air cooler. An axial ventilation channel is arranged on the rotating shaft; a radial rotor air vent is arranged on a rotor iron core; a radial stator air vent is arranged on a stator iron core; a baffle is fixedly arranged in the axial ventilation channel; the left end of the rotating shaft is fixedly connected with a left centrifugal fan, and the right end of the rotating shaft is fixedly connected with a right centrifugal fan; and a rotor winding connection wire end is located at the right side of a fixed rotor, and a stator winding connection wire end is located at the right side of the fixed rotor. The generator disclosed by the invention is in a ventilation structure and has the good heat radiation effect. The ventilation structure of the air-to-air cooling double-fed asynchronous wind driven generator can be widely applied to double-fed asynchronous wind driven generators.

Description

technical field [0001] The invention relates to an air-to-air cooling double-fed asynchronous wind generator, in particular to a low-temperature lift-off air-cooled double-fed asynchronous wind generator with a mixed ventilation structure. Background technique [0002] The existing air-to-air cooling doubly-fed asynchronous wind power generator includes a base, a rotating shaft, a stator, a rotor, and an air-to-air cooler located above the base; the base is supported with several annular ribs with an outer square and an inner circle (outer square inner circle Refers to the outer side of the annular rib plate is square and the inner side is round), the inner wall of the annular rib plate is fixed with several axial rib plates for supporting the stator; The air inlets at both ends and the air outlet in the middle of the base; there are several axial air passages on the rotating shaft, and several rotor radial air holes communicating with the axial air passages on the rotor...
