Nacelle Cooling Loop
Water-glycol coolant headers circulate between the generator cold-plates, power converter and nacelle roof heat exchangers at loop temperatures from 45 °C to 70 °C. Generator and gearbox meshing excitation reaches 200 Hz — DIN 3015 cushion inserts damp vibration transmission to structure and maintain preload without creep across a 20-year service life.
