Abstract

A system for the handling of the heat loads produced by a wind turbine. The present invention proposes a novel method (and various arrangements for its materialization) based on the transfer of the heat loads from the nacelle to a 'meeting point' where these heat loads are being transferred -through a device called, as 'thermal carrier' (100) to a cooling liquid which circulates between the aforementioned 'meeting point' and a still heat exchanger located remotely from the nacelle. One principal aspect of this invention is that the cooling liquid arrives at the 'meeting point' (and leaves the 'meeting point') under ambient atmospheric pressure. A pump (2) draws coolant form a heat exchanger (1) and transfers this coolant to a still nozzle (3) located near the thermal carrier (100) which is rotating simultaneously with the nacelle, around a vertical axis, during the continuous re-orientation of the wind turbine to the direction of the wind. The nozzle (3) injects a spray of coolant which covers a distance before its landing on the surface of the thermal carrier. Therefore, under ambient pressure, the coolant removes heat load from the thermal carrier and fells, due to the gravity, inside a heat bowl (12) from where it is re-introduced inside a heat exchanger which is located, usually, in a still position and, preferably, outside of the pylon.
