A wind power installation includes a nacelle, and energy conversion system for converting wind power into electric energy. The energy conversion system includes a heat-generating source which is disposed in the nacelle and constructed to include a closed primary cooling system using air for dissipating generated heat. Further provided is an open secondary cooling system which uses ambient air for cooling heated air from the primary cooling system.

Wind power installation with separate primary and secondary cooling circuits

A wind power installation includes a nacelle for housing a generator, and a turbine having at least one rotor blade. At least the generator includes a closed primary cooing system, and the nacelle is provided with a cooling system for cooling the primary cooling system in dependence on an output of the generator or generator losses.

A shock-proof electric marine engine, e.g. an engine or generator, is for a marine (Navy) ship, and includes a stator and a rotor in a housing. The stator and the rotor are connected in such a way that they are rotatably displaceable in a counter direction and in a radial/axial manner with limited slack. The rotor and stator form a displaceable unit in relation to the housing, which can be displaced away from the housing with a higher vibration overshoot range. The housing is elastically connected to the marine (navy) ship.
