Benefits of technology

[0013]For improving the cooling effect of the nacelle, the nacelle can be completely or partially made out of metal. It is preferable to use aluminum as the metal in order to also take advantage of the cooling effect of an outer surface area of the nacelle, which is constantly enveloped by wind, and thus to increase the wind turbine cooling. The outer surface area of the nacelle is cooled by atmospheric wind.

Problems solved by technology

This is particularly disadvantageous if the outside air is humid or, particularly in coastal regions, if it has a high salt content, and the cooling elements are then exposed to this humid and high salt content air.
This problem is especially extreme with wind energy facilities that stand directly on a coast or, in offshore technology, directly in salt water.
Another problem is the environmental contamination of air heat exchanges being clogged and blocked.

Embodiment Construction

[0021]With reference now to the drawings, and particularly to FIG. 1, there is shown a side view of a wind turbine 1. The wind turbine 1 preferably includes a nacelle 4, a rotor 6, a pivot system 8 and a tower 10. The nacelle 4 is pivotally retained on a top of the tower10 with the pivot system 8. A bottom portion of the tower 10 is anchored in the ground (not shown). The nacelle 4 houses a rotor drive shaft, generator and other components of the wind turbine 1. The components found in the nacelle 4 are well known in the art and need not be shown or explained in detail. The rotor 6 extends from an end of a rotor drive shaft 9. The rotor 6 includes a plurality of blades 7 and the rotor drive shaft 9.

[0022]With reference to FIGS. 2-3, the nacelle 4 includes a shaft housing 12, a reservoir housing 14 and a plurality of external cooling fins 16. The shaft housing 12 may be secured to the reservoir housing 14 with any suitable method. The rotor drive shaft 9 is inserted through a drive s...

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.

Description

BACKGROUND OF THE INVENTION[0001]1. Field of the Invention[0002]The present invention relates generally to wind turbines and more specifically to a wind turbine with improved cooling, which provides improved cooling for components of the wind turbine.[0003]2. Discussion of the Prior Art[0004]Most wind turbines use heat transfer devices, such as fans to dissipate heat into the environment. In this way, cold air is suctioned in from the outside by the fans to cool wind turbine components such as the generator. The heated air is then blown back outside. Some wind turbines transfer component heat within a nacelle to a heat exchanger mounted external on the nacelle for atmosphere environment air to pass through and transfer the heat.[0005]All of these known solutions have in common a large amount of air that is always needed from the outside. This is particularly disadvantageous if the outside air is humid or, particularly in coastal regions, if it has a high salt content, and the coolin...
