Abstract: A method and system are provided for cooling a heat-exchanger in a wind turbine that has an electric generator with a cooling air flow directed therethrough. Effluent cooling air flow from the electric generator is directed into an air ejector pump and acts as motive air through the air ejector pump. Cold air is drawn into the air ejector pump by the vacuum generated by the motive air moving through the air ejector pump. The heat exchanger is disposed in-line with the cold air flow so that the cold air is drawn through the heat-exchanger, removes heat from the fluid circulated through the heat-exchanger, and becomes heated air that is combined with the motive air and discharged from the nacelle.
