Wind turbine cooling system and wind turbine

Abstract

The invention relates to a wind generating set cooling system and a wind generating set. The wind generating set cooling system comprises an air inlet, a centrifugal fan and a control system, wherein the air inlet is formed in the wall of a tower barrel of the wind generating set; the centrifugal fan is communicated with the air inlet; the control system comprises a master control system, a temperature sensor and a wind speed sensor; the master control system is used for controlling the centrifugal fan; and the temperature sensor and the wind speed sensor are arranged in the tower barrel, and are electrically connected with the control system. The wind generating set cooling system can automatically control the centrifugal fan according to changes of a temperature and a wind speed of the wind generating set; even if the system resistance in the wind generating set is greater, stable wind can be provided to the interior of the wind generating set, and ventilates and cools a heating component in the wind generating set timely, and normal operation of the wind generating set can be guaranteed.

Description

technical field [0001] The invention relates to the technical field of heat dissipation of wind power generators, in particular to a heat dissipation system of wind power generators and a wind power generator with the heat dissipation system of wind power generators. Background technique [0002] As the capacity of wind turbines increases, the calorific value of wind turbines also increases, resulting in the fact that the original method of cooling wind turbines by natural wind can no longer meet the requirements. Forced cooling must be used to cool the entire wind turbine. Heat dissipation. [0003] At present, fans are usually used to cool the inside of the wind turbine with forced ventilation, but the existing fan cooling system cannot adjust the fan according to the temperature and wind speed changes in the wind turbine, resulting in poor air supply adaptability of the fan cooling system, especially in wind turbines.

[0002] As the capacity of wind turbines increases, the calorific value of wind turbines also increases, resulting in the fact that the original method of cooling wind turbines by natural wind can no longer meet the requirements. Forced cooling must be used to cool the entire wind turbine. cooling

[0003] At present, fans are usually used to cool the inside of the wind turbine with forced ventilation, but the existing fan cooling system cannot adjust the fan according to the temperature and wind speed changes in the wind turbine, resulting in poor air supply adaptability of the fan cooling system, especially in wind turbines. When the internal air supply resistance of the generator set is large, the air volume flowing to the upper part of the tower and the nacelle is insufficient, and the desired cooling effect cannot be achieved, and the heating components in the wind turbine generator set are prone to overheating faults
