Abstract

The present invention proposes a technique that provides cooling arrangement for offshore wind turbines. Piles of tower foundations are used as flow channels for the coolant and sea water as heat sink. The cooling arrangement is inside bottom of tower which blows cool air to tower bottom. The cool air is blown with the help of a fan or blower and sucks the hot air to circulate through the foundations where the cooling arrangement loses heat and then returns back to tower bottom. A flow path is created for cooling air or liquid to circulate through the foundation piles or tubes.

OFFSHORE WIND TURBINE COOLING ARRANGEMENT

BACKGROUND

The present invention generally relates to a wind turbine and more particularly to a technique for providing offshore wind turbine cooling arrangement.

In general, power electronics, such as, down tower assembly (DTA) in a wind turbine is expensive. Conventional cooling techniques are not optimum in terms of cost.

A conventional technique includes a cavity formed inside a foundation. The foundation has chambers where heated air gets in and heat is transferred to water and then returns back to the tower. However, the technique requires additional cost in configuring cavity inside the foundation.

Therefore, there is a need in the art for a technique to cool offshore wind turbines in a cost effective manner.

BRIEF DESCRIPTION OF THE DRAWINGS

Figure 1 depicts proposed technique design and examples of offshore foundations where the proposed technique is implemented.
