摘要（英）：

The invention provides an air heat exchanger leakage detection system and method and a wind driven generator. The air heat exchanger leakage detection system comprises an air heat exchanger, a first air valve, a first fan, a pressure sensor and a controller. The air heat exchanger is used for carrying out heat exchange between an air cooling system and external environment. The first air valve is used for closing an inner circulation air flue of the air cooling system. The first fan is installed in the inner circulation air flue of the air cooling system. The pressure sensor is installed in the inner circulation air flue of the air cooling system and used for detecting gas pressure. The controller is used for controlling the rotating speed and/or direction of the first fan and receiving pressure data detected by the pressure sensor. According to the air heat exchange leakage detection system, the problems that the air heat exchanger is difficult to overhaul and leakage of the air heat exchanger cannot be found in time in practical application of the wind driven generator are solved, the cooling system can be conveniently overhauled, and fault problem can be found in time.
