Wind-power-generator fan unit and wind power generator

Abstract

There are provided a wind-power-generator fan unit and a wind power generator in which the consumption of driving power for a cooler fan that cools a device provided in the wind power generator can be reduced. This wind-power-generator fan unit includes cooler fans that discharge air in a housing that accommodates devices that perform at least power generation by the rotational operation of rotor blades to the outside of the housing through the devices; and a control unit that controls the operation of the cooler fans on the basis of the temperatures of the devices and the operating states of the devices.

1 . A wind-power-generator fan unit comprising:
 a cooler fan that discharges air in a housing, which accommodates a device that performs at least power generation by rotational operation of rotor blades, to an outside of the housing through the device; and   a control unit that controls operation of the cooler fan on a basis of a temperature of the device and an operating state of the device.   
     
     
         2 . The wind-power-generator fan unit according to  claim 1 , wherein the control unit estimates the operating state of the device on a basis of results of measurement by an anemoscope/anemometer that measures a wind direction and a wind speed outside the housing and controls the operation of the cooler fan. 
     
     
         3 . The wind-power-generator fan unit according to  claim 1 , wherein the control unit estimates the operating state of the device on a basis of a rotational speed of the rotor blades and a pitch angle of the rotor blades and controls the operation of the cooler fan. 
     
     
         4 . The wind-power-generator fan unit according to  claim 1 , wherein the control unit estimates the operating state of the device on a basis of power output from the device and controls the operation of the cooler fan. 
     
     
         5 . The wind-power-generator fan unit according to  claim 1 , wherein
 the cooler fan is provided for each of a plurality of the devices; and   the control unit controls the operation of one of the cooler fans on a basis of the operating state of another of the cooler fans.   
     
     
         6 . A wind-power-generator fan unit comprising:
 a plurality of cooler fans, for a plurality of devices that performs at least power generation by rotational operation of rotor blades, that discharges air in a housing accommodating the devices to an outside of the housing through the devices; and   a control unit that controls operation of one of the cooler fans on a basis of a temperature of the device and an operating state of another of the cooler fans.   
     
     
         7 . A wind power generator comprising:
 a rotor blade that is driven by wind;   a device that performs at least power generation by rotational operation of the rotor blade;   a housing that accommodates the device in an interior thereof; and   a wind-power-generator fan unit according to  claim 1 .
