To provide a cooling device for an offshore wind force energy apparatus, effectively preventing excessive biological fixation to ensure the operation with a little maintenance by improving the device including a heat absorbing device for absorbing heat to be led out, a radiating device for discharging heat to water 14 existing in the periphery, wherein the heat absorbing device has a first cooling circuit operated by liquid-like refrigerant, the first cooling circuit discharges the absorbed heat to the radiating device 12 in a heat exchanger 20, and the radiating device 12 has a second cooling circuit 22 operated by water 14 as a refrigerant.
Two or more electrodes 36a, 36b, 36c, 36d, 36e, 36f are disposed at spaces from each other in the drawing direction of the second cooling circuit in an inner wall of a duct line 30 of the cooling circuit 22, and the electrodes are connected to a voltage supply device 38 to generate AC high voltage at least between two electrodes.
