Abstract

The invention discloses a cooler applicable to a wind generating set. A fan is fixedly connected onto a motor shaft; a cooling core is arranged at the front end of the fan; a hairbrush is arranged onthe outer side face and / or the inner side face of the cooling core and is fixed on a hairbrush framework; a second transmission shaft for rotating the hairbrush framework is linked with the motor shaft through a clutch; a motor is driven by a PLC; when the motor rotates forward, the clutch is in the separating state; and when the motor rotates reversely, the clutch is in the closing state. The PLCcontrols forward and reverse rotation of the motor; when the motor rotates forward, the fan sucks cooling air passing through the cooling core; when the motor rotates reversely, the motor is linked with a cleaning device through the clutch, and the fan rotating reversely enhances the cleaning effect; a temperature sensor is adopted to detecting the temperature of coolant to feed the temperature back to the PLC, the PLC controls forward and reverse rotation of the motor to realize automatic operation and automatic cleaning operation of the cleaning device, so that the cooler plugging problem is effectively solved; and the cooler has high practicality and wide applicability.

Description

technical field

[0001] The invention relates to a cooler, in particular to a cooler suitable for wind power generating sets, and belongs to the technical field of wind power generation industry. Background technique

[0002] There are many heat-generating equipment during the operation of wind turbines, mainly including gearboxes, generators and frequency converters.

[0003] At present, large-scale MW-level wind turbines generally dissipate the heat generated by gearboxes, generators, and frequency conversion cabinets by installing oil cooling and water coolers.

[0004] The cooling effect of the cooler is mainly affected by the air flow inhaled by the cooling fan, but in the actual operation process, the dust particles and flocs in the air will be adsorbed on the surface of the air inlet of the cooling core, causing the air circulation to be blocked, which in turn will cause the wind turbine generator Overheating protection, reducing power or stopping power generation wil...
