A method of controlling a wind turbine is provided including at least one fan-cooled unit with a fan adapted to circulate air inside a housing of the fan-cooled unit, which method includes operating the fan-cooled unit in a dryout mode by: disabling a thermal energy reduction the fan-cooled unit, which thermal energy reduction means is adapted to reduce thermal energy of air inside the housing during a normal operation mode of the fan-cooled unit; actuating a fan of the fan-cooled unit to circulate the quantity of air contained in the housing; and monitoring a climate parameter until a target climate condition has been reached. A wind turbine configured to execute the steps of the inventive method is also provided.

A wind turbine has a wind turbine gearbox, a generator and/or a converter arranged inside a nacelle of the wind turbine. The wind turbine further has a liquid cooler arranged to cool a liquid flowing through the wind turbine gearbox, the generator and/or the converter by way of air ambient to the nacelle. The liquid cooler includes a first liquid cooler part having a first part cooling capacity and a second liquid cooler part having a second part cooling capacity, wherein the second part cooling capacity is greater than the first part cooling capacity. The liquid cooler also includes a bypass conduit arranged to guide a liquid from the first liquid cooler part past the second liquid cooler part, and valve means arranged to control flow through the bypass conduit, wherein the valve means are controlled based on at least one characteristic of the liquid flowing through the liquid cooler. A method for cooling a liquid is also provided.

A tower base automatic ventilation system for thermal convective wind power generation device, comprising: an duct body, which is a bottom-up extended molding structure for blowing hot air from the lower end of the duct body to the upper end of the duct body to form wind power; and a power generator, which is located in the holding chamber, and the power generator includes a driving shaft, rotating fan blades, and a power generation unit, and the rotating fan blades are rotatable by the driving shaft in the holding chamber, and the rotary fan blade is configured to start generating electricity by rotating at a high speed by the high efficiency blade group driven by the wind beam flowing from the bottom of the duct body to the top of the duct body due to the convection current and rapidly drive the power generation unit and continuously generate electricity.

A wind turbine with a tower and a nacelle with a nacelle housing is provided. The nacelle is placed on the tower. Further provided is a cooling flap, which is configured to close an opening in or on the area of the wind turbine to be cooled. At least one temperature-dependent passive actuator is configured to activate and open the cooling flap as a function of temperature, so as to enable a heat compensation in the area to be cooled by means of the opening. The temperature-dependent passive actuator can change its shape and/or its length without any external electrical energy as a function of temperature.

A wind turbine with adaptive nacelle preferably includes a geared blade shaft; and at least one reciprocating generator unit. The geared blade shaft includes a plurality of blade magnets attached to an outer perimeter of the blade shaft, which extend a portion of a length of the blade shaft. Each reciprocating generator unit preferably includes an intermediate magnetic gear, at least one magnetic generator gear, at least one electrical generator, at least one actuator and a retention frame. The intermediate magnetic gear and the at least one generator magnetic gear are pivotally retained in the retention frame. The at least one electrical generator is retained on the retention frame. The at least one actuator is used move the reciprocating generator unit to engage rotation of the geared blade shaft with the intermediate magnetic gear. Rotation of the geared blade shaft causes rotation of the electrical generator.
