AB - The efficiency of cooling system is critical for wind turbines, particularly  during the hot season, when high temperatures could damage the electric  generator and mechanical parts of the turbine. The cooling system proposed in  this paper is able to increase the efficiency of heat transfer with the use  of nanofluids and the wind turbine tower as a heat exchanger to dissipate  waste heat in the environment. In this study the use of Al2O3-water  nanofluids has been considered. The results of this investigation appear  encouraging because they have shown that the proposed new solution is able to  assure highly efficient heat transfer and to limit thermal stresses on the  electrical and mechanical components of wind turbines.
