Embodiment

[0023] see Figure 1-3 , the present invention provides a technical solution: an air-cooled wind power generator set, including a blade 1, a hub 2, a gearbox 3, a generator 4, a nacelle 5 and a tower 6, the blade 1 is installed on the hub 2, and the hub 2 rotates Installed at one end of the nacelle 5, the gearbox 3 and the generator 4 are located in the inner chamber of the nacelle 5, the output shaft of the gearbox 3 is connected to the rotor shaft of the generator 4 through a coupling, and the input shaft of the gearbox 3 is connected to the hub 2 , the nacelle 5 is horizontally installed on the top of the tower 6;

[0024] The wind turbine is mainly composed of blades 1, hub 2, generator 4, nacelle 5, tower 6, gearbox 3, converter and other components. The blade 1 absorbs the incoming wind energy and converts the wind energy into the rotational mechanical energy of the impeller system, thereby driving the coaxial gearbox 3. After speeding up, the generator 4 converts the m...

Abstract

The invention belongs to the technical field of wind power generation, and particularly discloses an air cooling type wind generating set. The air cooling type wind generating set comprises blades, ahub, a gear box, a generator, a cabin and a tower rack. The blades are mounted on the hub. The hub is rotationally mounted at one end of the cabin. The gear box and the generator are located in an inner cavity of the cabin. An output rotating shaft of the gear box is connected with a rotor shaft of the generator through a coupling. An input rotating shaft of the gear box is connected with the hub.The cabin is transversely mounted at the top end of the tower rack. A first heat exchanger, a second heat exchanger, a third heat exchanger, a unit heat exchanger and a circulating pipeline are further arranged in the tower rack, unit heat radiation can be achieved well, and the temperature level is further reduced. By means of the unit area temperature control manner fully utilizing natural resources, systematic temperature control and lower unit energy consumption are achieved. Heat in the tower rack is adjusted and controlled from top to bottom, and the heat in the tower rack is adjusted and controlled to be uniform.

Description

technical field [0001] The invention relates to the technical field of wind power generation, in particular to an air-cooled wind power generating set. Background technique [0002] A wind turbine is a device that converts wind energy in nature into electrical energy, and the corresponding electrical energy is a green and clean energy. With the increasing capacity of the wind turbine unit, the heat loss of the various subsystems and components of the unit itself is increasing. According to incomplete statistics, the heat loss of the unit itself accounts for almost 8% to 10% of the unit capacity of the unit. For example: if a single unit For a unit with a capacity of 10MW, the heat loss value of the unit itself is as high as nearly 1MW, which shows that the heat loss value is quite considerable. A problem directly caused by the huge heat loss is the heat dissipation problem, how to efficiently and quickly dissipate the heat generated by the unit itself. Contents of the inv...
