Abstract

The invention provides a heat dissipation structure of a wind driven generator and a wind power generation device, and relates to the technical field of wind power generation equipment. The heat dissipation structure of the wind driven generator comprises a stator assembly, a rotor assembly and a heat dissipation device. The rotor assembly and the stator assembly are rotatably matched and form a gap. And the heat dissipation device introduces air flow into the gap. The stator assembly comprises a stator core, a stator support and a stator winding. A plurality of ventilation openings are formed in the stator core. The stator support is provided with an air inlet channel and an air outlet channel. The air inlet channel and the air outlet channel are both communicated with at least one ventilation opening. And the air outlet channel is configured to lead in airflow from the ventilation opening and lead out from the inner side of the stator bracket. The heat dissipation device is further configured to guide airflow into the air inlet channel and guide the airflow out of the ventilation opening. The wind power generation device provided by the invention adopts the heat dissipation structure of the wind power generator. According to the wind driven generator heat dissipation structure and the wind power generation device, the problem that in the prior art, the cooling and heat dissipation effect is poor can be solved.

Description

technical field [0001] The invention relates to the technical field of wind power generation equipment, in particular to a heat dissipation structure of a wind power generator and a wind power generation device. Background technique [0002] Nowadays, in order to promote green environmental protection, the demand for pure energy is increasing, for example, wind power generation. The generators used in wind power generation will generate a lot of heat during operation. If the temperature is too high, the operating power of the motor will be affected, thereby affecting the power conversion rate of wind power generation. Therefore, it is necessary to machine for cooling. [0003] In the prior art, air cooling is usually used to provide cooling to wind power generators, but in general, the air cooling method has a low cooling effect on the windings of the generator, resulting in poor heat dissipation of the generator. Well, it will lead to a reduction in the conversion rate of...
