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.

What is claimed is: 1. A wind power installation, comprising: a nacelle; energy conversion means for converting wind power into electric energy, said energy conversion means including a heat-generating source disposed in the nacelle and constructed to include a closed primary cooling system using air for dissipating generated heat; and an open secondary cooling system received in the nacelle and using ambient air for cooling heated air from the primary cooling system. 2. The wind power installation of claim 1, wherein the secondary cooling system is thermally coupled to the primary cooling system. 3. The wind power installation of claim 1, wherein the secondary cooling system is constructed in the form of a tube bundle having tubes aligned in parallel relationship to a wind direction. 4. The wind power installation of claim 1, wherein the primary cooling circuit includes a tubular member which has the shape of a grip and extends to an area outside the nacelle, with the secondary cooling system being realized by freely flowing ambient air. 5. The wind power installation of claim 4, wherein the tubular member has a first port, disposed in an upper portion of the nacelle for receiving heated air from the heat-generating source, and a second port, disposed at a location below the outlet, for returning cooled air into the nacelle. 6. The wind power installation of claim 4, and further comprising a fan for assisting a circulation of air through the tubular member of the primary cooling circuit.
