Wind Generator Air to Air Indirect Cooling System

Wind power system background

Wind power is a kind of clean energy, with the characteristics of renewable, pollution-free, large energy and broad prospects. The development of clean energy is the strategic choice of all countries in the world.

However, if the air is directly fed into the generator cabin for cooling, the dust and corrosive gas will be brought into the cabin (Especially wind turbines installed offshore).

Indirect cooling system solution

The indirect cooling method can make the air from inside and outside perform indirect heat exchange to achieve the effect of cooling the wind generator cabin without bringing dust and corrosive gases from outside into the cabin.

The main component of the indirect cooling system is the BXB plate heat exchanger. In the BXB plate heat exchanger, two channels are separated by aluminum foil. The air in the cabin is closed circulation, and the outside air is open circulation. The two airs are doing heat exchange. The air in the cabin transfers heat to the outside air, which reduces the temperature in the wind generator. In addition, the air inside and outside the cabin will not be mixed due to the isolation of aluminum foil, which prevents dust and corrosive gases outside the cabin from being brought into the cabin.
