초록

A cooling system 44 for an electrical generator 42 is disclosed. The cooling system rejects excess heat to the engine fuel through a primary heat exchanger 46 and at low fuel flow rates, supplementarily rejects heat to fan air at a secondary heat exchanger 48 located remotely from the fan duct 30. In one embodiment, the secondary heat exchanger is disposed in a nacelle fan compartment 14. In another embodiment, the secondary heat exchanger is disposed in a nacelle core compartment 16.
