Problems solved by technology

Air cooling is to use the air with a lower ambient temperature to cool the heat-generating components in the unit. However, if the installation environment temperature of the unit is high, the temperature of the outside air will also be high, and the cooling effect is not ideal.

Description

technical field [0001] The invention relates to wind power generation technology, in particular to a cooling device, a cooling system and a wind power generating set for a wind power generating set. Background technique [0002] In modern large-scale wind turbines, as the power generated by a single machine increases, the heat generated by the heat-generating components inside the wind turbine is also increasing, especially for units that have been in a high-temperature environment for a long time. This requires the design of a novel cooling device for wind turbines to cool its internal heat-generating components, so as to ensure that the wind turbines can operate safely and without failure in a high-temperature environment. [0003] At present, wind turbines are mostly cooled by air cooling. Air cooling is to use the air with lower ambient temperature to cool the heat-generating components in the unit. However, if the installation environment temperature of the unit is hig...
