An engine driven generator () is provided with first and second stage fans () at one end thereof. The two-stage fan system draws in ambient air and forces it through the generator windings () and rotor-stator air gap () for the purpose of improving generator cooling. Stationary guide vanes () are disposed between the two fans () for the purpose of de-swirling the flow therebetween. The fans are of the centrifugal type and are preferably backward curved.

Two-stage cooling fan for an electric generator

A wind turbine with improved cooling, which provides liquid cooling for a wind turbine with a completely closed or at least partially closed cooling circuit, with which the heat to be dissipated from the cooling circuit is dissipated by a nacelle of the wind turbine. The wind turbine with improved cooling dissipates energy losses from heat and applied for the conversion of kinetic energy of wind into mechanical and electrical energy of the wind turbine.
