  • Two-stage cooling fan for an electric generator
    Patent number: 8125110
    Abstract: An engine driven generator (17) is provided with first and second stage fans (41,42) at one end thereof. The two-stage fan system draws in ambient air and forces it through the generator windings (38) and rotor-stator air gap (37,39) for the purpose of improving generator cooling. Stationary guide vanes (49) are disposed between the two fans (41,42) for the purpose of de-swirling the flow therebetween. The fans are of the centrifugal type and are preferably backward curved.
    Type: Grant

  • Wind turbine with improved cooling
    Patent number: 7963743
    Abstract: 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.

  • ELECTRIC GENERATOR DRIVEN BY COMBUSTION ENGINE AND HAVING FLUID COOLING
    Publication number: 20110042967
    Abstract: A combustion engine driven electrical generator includes a generator shaft to be driven by a combustion engine shaft. The generator shaft rotates near stator windings. An electrical terminal connection delivers generated electricity to a user. A cooling fluid circuit provides flooded cooling fluid to the stator and rotor windings. The oil or cooling fluid circuit takes hot cooling fluid from the generator and passes the hot cooling fluid through a cooler heat exchanger, and then back into the generator housing.
