Abstract
The invention discloses a cooling system of a 1.5MW wind turbine, which comprises a primary wind path and a secondary wind path, wherein, the primary wind path comprises two axial fans (4), an axial centrifugal fan (5), a wind shield (3) and a cooler (2), the axial fans (4) and the axial centrifugal fan (5) are mounted on a shaft, and the wind shield (3) and the cooler (2) are located on rotors (6); and the secondary wind path comprises a radial centrifugal fan (1), and two radial fans located inside the housing of an engine. By adopting the cooling arrangement combining the primary wind pathand the secondary wind path, the invention has the following advantages of high wind volume, high wind speed and low wind friction, wherein, the wind friction of the wind turbine can be controlled ata lower level while the requirements on temperature rise can be met; and the invention further has the advantages of simple structure and high turbine efficiency.
Description
Technical field
The present invention relates to a kind of engine-cooling system, particularly relate to a kind of 1.5MW wind-driven generator cooling system.
Background technology
Early stage wind-driven generator is because power is less, and its caloric value is also little, only needs just can reach the cooling requirement by natural draft effectively.Yet along with the power of wind-driven generator progressively increases, natural draft can't have been satisfied the cooling requirement of unit.In order to strengthen cooling effect, adopt by fan being set in wind-driven generator inside, thereby being carried out forced-air blast, each parts in the blower fan reach cooling effect.The air quantity of fan is big in theory, wind speed is high beneficial to the temperature rise of further reduction generator, but this can cause cooling fan oversize, and then has increased the abrasion of generator wind, and generator efficiency is reduced.Therefore, how to make the wind abrasion of generator can be controlled at reduced levels and can guarantee that its temperature rise meets the requirements and just become one of difficult problem that big capacity wind motor cooling system faces.
Summary of the invention
The objective of the invention is to overcome the deficiencies in the prior art, the big capacity wind-driven generator cooling system that a kind of air quantity is big, wind speed is high, the wind abrasion is little is provided.
The technical scheme that adopts for goal of the invention of the present invention is: 1.5MW wind-driven generator cooling system, it is made up of wind path and secondary wind path, wherein, wind path comprises that two are installed in axial fan 4, axial-centrifugal fan 5 on the axle, are positioned at deep bead 3 and cooler 2 on the rotor 6; The secondary wind path comprises radially centrifugal blower 1 and two radial fan that are positioned at engine outer cover inside.
The course of work of the present invention is:
A wind path: the cooling air of motor (cooling air) is produced by two axial fan and axial-centrifugal fans that are installed on the axle, enter rotor core by deep bead, and (the one tunnel arrives winding overhang to be divided into two-way at motor internal, another road is then by the core ventilation ditch) draw the heat of heat generating components, synthetic back hot-air flows to into aerial cooler, by it motor heat is discharged to (secondary cooling air) in the surrounding air.
The secondary wind path: the aerial cooler that this motor has been equipped band radially outer fan is done secondary circuit and is ventilated, and is undertaken him by centrifugal blower radially and fans cold.Is made up of the radial ventilation pipeline in this cooler outer cover, two radial fan that are positioned at outer cover inside are taken out secondary cooling air and through there being air pipe that air is extruded.
Because the combination type of cooling that has adopted wind path and secondary wind path to combine, not only air quantity is big, wind speed is high for 1.5MW wind-driven generator cooling system provided by the invention, and the wind abrasion is little, the wind abrasion of generator can be controlled at reduced levels and can guarantee that its temperature rise meets the requirements, and has advantage simple in structure, that generator efficiency is high.
