Embodiment Construction

[0032] figure 1 A wind turbine 1 is shown comprising a tower 2 mounted on a foundation and a nacelle 3 arranged at the apex of the tower 2 . The wind turbine 1 described herein is an onshore wind turbine such that the foundation is embedded in the ground, but the wind turbine 1 may be an offshore installation, in which case the foundation will be provided by a suitable offshore platform.

[0033] The rotor 4 is coupled in operation via a gearbox to a generator housed inside the nacelle 3 . The rotor 4 comprises a central hub 5 and a plurality of rotor blades 6 protruding outwardly from the central hub 5, it should be noted that the wind turbine 1 is a common type of horizontal axis wind turbine (HAWT) such that the rotor 4 is mounted It rotates at the nacelle 3 about a substantially horizontal axis defined at the center of the hub 5 . although figure 1 The example shown has three vanes, but those skilled in the art will recognize that other numbers of vanes are possible.

Abstract

A wind turbine cooling system comprising a cooling circuit arranged to convey a cooling fluid to and from a heat source, a cooling device arranged to cool the cooling fluid, a pump arranged to circulate the cooling fluid in the cooling circuit, and a cooling fluid tank arranged in fluid connection with the cooling circuit and having a first fluid port adjacent a top of the tank and a second fluid port adjacent a bottom of the tank, wherein the second fluid port is arranged to communicate with the cooling circuit, wherein the pump has an outlet arranged in fluid connection with the cooling circuit and in fluid connection with the tank, and wherein a fluid path between the pump outlet and the tank includes a flow restriction device.

Description

technical field [0001] The invention relates to a wind turbine cooling system, a wind turbine having such a cooling system and a method of operating a wind turbine cooling system. Background technique [0002] Wind turbines convert wind power into electrical energy using generators placed between other wind turbine components in the nacelle. When the generator converts the wind into energy, the walls and the air surrounding the component are heated, and thus the component. [0003] When these components are heated, the efficiency with which conversion occurs is significantly reduced. To cool the components, the walls and the air surrounding the components are cooled down by means of radiators positioned on the roof of the nacelle (the so-called "cooler roof"). Thus, cooled outside air passes through the radiator and cools the circulating cooling fluid within the radiator, which is then used to cool the walls and / or the air surrounding the component by circulating the cooli...
