A wind turbine generator () includes a tower (), a nacelle () rotatably mounted to the tower (), the nacelle having a longitudinal axis and being configured to align the longitudinal axis with the direction of the incoming wind during operation of the wind turbine generator (), one or more heat-generating components () housed in the wind turbine generator (), and a containerized HVAC module () mounted on a roof () of the nacelle () and operably connected to the one or more heat-generating h components () for cooling the heat-generating components (). The module () includes a shipping container () having a floor (), a roof (), a pair opposed longer side walls (), a pair of opposed shorter end walls (), and a longitudinal axis, the longitudinal axis of the shipping container () being oriented generally perpendicular to the longitudinal axis of the nacelle (), the shipping container () having at least one heat exchanger () therein.

Rooftop containerized HVAC module for wind turbine generator

A wind turbine () includes a nacelle () with a longitudinal axis (LA) aligned with the flow of the incoming wind during operation. When so aligned, the nacelle defines a longitudinal direction (X). The wind turbine () includes one or more heat-generating components () and a modular cooler () operatively coupled to the one or more heat-generating components (). The modular cooler () includes one or more cooling modules () with each including one or more cooling units (). Each cooling unit () includes a heat exchanger () defining a cooling area (), which defines a normal axis (NA) and a deflector plate () to divert the flow of the incoming wind by an angle less than 180° relative to the longitudinal direction (X). Each cooling unit () is oriented such that the normal axis (NA) is non-parallel to the longitudinal axis (LA). The modular cooler () is scalable in multiple dimensions to increase the cooling capacity of the cooler (). A method of assembling the modular cooler () is also disclosed.

A wind turbine () includes a tower (), a nacelle () coupled to the tower () and housing one or more heat generating components (), a rotor () having a least one wind turbine blade (), and a cooler () mounted to the nacelle () and configured to cool the one or more heat generating components () in the nacelle () by circulating a working fluid. The cooler () includes a support frame () coupled to the nacelle () and a heat exchanger () coupled to the support frame () and configured to cool the working fluid. The heat exchanger () includes at least two cooling panels () in non-planar relation with each other. The at least two cooling panels () may also be pivotably coupled to each other. A method of assembling a cooler () is also disclosed.

Cooler for a wind turbine having pivotable cooling panels

A heli-hoist pad that is incorporated into a wind turbine nacelle in a manner that is optimized for helicopter approach and positioning of the heli-hoist pad, such as by being located within a recess in an upper surface of the wind turbine nacelle. Heat exchangers may also be positioned within the free flow of wind outside of a nacelle in manners that provide for serviceability while also allowing for optimal positioning of a heli-hoist pad.

Nacelle construction for a wind turbine

A wind turbine with a tower; a nacelle supported by said tower; at least one unit to be cooled and arranged in the tower or the nacelle; a tower mounted heat exchange structure arranged outside the nacelle and tower; and a circuit facilitating a flow of a fluid medium between the at least one unit and the heat exchange structure. To improve thermal convection with the ambient space, the heat exchange structure comprises a set of panels mutually angled and extending outwards from the tower such that a flow of ambient air can pass transversely trough the panels and thereby cool the unit.

A method of starting up a wind turbine includes heating first and second components, the first component having a first minimum operating temperature and the second component having a second minimum operating temperature. Excess heat is generated after the second component has been heated to the second minimum operating temperature. The excess heat is transferred to the first component to assist heating the first component to the first minimum operating temperature. The first and second components are cooled after reaching the first and second minimum operating temperatures.

A wind turbine having a cooling system, which wind turbine includes a nacelle in connection with which one or more wind turbine components are arranged, is disclosed. The cooling system includes at least one cooling circuit arranged to lead a heat transfer medium to and from one or more of the wind turbine components, at least one cooling device arranged to cool the heat transfer medium, at least one pump arranged in connection with the at least one cooling circuit to circulate the heat transfer medium in the cooling circuit, and at least one medium tank arranged in connection with the cooling circuit. The at least one medium tank is arranged inside the nacelle.

Cooling system for a wind turbine

The invention provides a wind turbine wind turbine with two vessels, each being interchangeably in thermal communication with a heating medium which transfers heat from a heat generating structure to the vessel, and with a cooling medium which transfers heat from the vessel to an ambient space. The vessels form a compression structure which form part of a refrigerating circuit which can circulate a working fluid between the compression structure, a condenser and an evaporator. At the evaporator, cooling effect is obtained based on evaporation of a working fluid, and the cooling can be utilized for cooling a heat generating component in the wind turbine.
