Description

Technical Field

[0001] The utility model relates to the technical field of wind turbine generators, in particular to a heat dissipation device for wind turbine generator equipment. Background Art

[0002] The generator used in wind power generation will generate a large amount of heat during operation. When the temperature is too high, the operating power of the motor will be affected. In the prior art, air cooling is usually used to provide cooling for the wind power generator. However, in general, the air cooling method has a low cooling effect on the windings of the generator, which leads to poor heat dissipation of the generator, which will lead to a decrease in the power conversion rate and affect the efficiency of wind power generation.

[0003] After searching, the Chinese patent document application number is CN202110922106.7. The invention provides a wind turbine heat dissipation structure and a wind power generation device, which relates to the technical field of wind power generation equipment. The wind turbine heat dissipation structure includes a stator assembly, a rotor assembly and a heat dissipation device. The rotor assembly and the stator assembly are rotatably matched to form a gap. The heat dissipation device introduces airflow into the gap. The stator assembly includes a stator core, a stator bracket and a stator winding. A plurality of vents are formed on the stator core. An air inlet channel and an air outlet channel are provided on the stator bracket. The air inlet channel and the air outlet channel are both connected to at least one vent. The air outlet channel is configured to allow airflow to be introduced from the vent and exported from the inner side of the stator bracket. The heat dissipation device is also configured to introduce airflow into the air inlet channel and export the airflow from the vent. The wind power generation device provided by the invention adopts the above-mentioned wind turbine heat dissipation structure. The wind turbine heat dissipation structure and wind power generation device provided by the invention can improve the problem of poor cooling and heat dissipation effect in the prior art.

When there is too much dust accumulation inside the wind turbine, manual cleaning is required, which is time-consuming and labor-intensive. At the same time, dust accumulation will affect the normal operation of the wind turbine equipment and the heat dissipation effect of the wind turbine. Therefore, we need to propose a heat dissipation device for wind turbine equipment to solve the above problems. Utility Model Content
