Description
Technical field
The present invention relates to a kind of for the hollow cooler on the wind power generator, high-power wind turbine generator cooler particularly.
Background technology
The cooler of the generator on the existing 1.5MW wind power equipment connects circle by single exogenous wind transportation work style machine, ventilating cabinet, tube sheet, the heat exchanger tube of rectangular arranged, outer wind path side and forms.Cooler is installed on the generator, and the inside wind path of cooler links to each other with the inner chamber of generator.By the generator amature rotation, drive the wheel rotation of two ends of rotor, produce the wind bundle.The wind band is walked the heat that the motor loss produces, and enters from the middle part of cooler, through the outer tube surface of subcooler, gets back to motor cavity from the two ends of cooler, forms circulated air.The wind that exogenous wind transportation work style machine produces is through the pipe endoporus, carries out heat exchange with the hot blast of interior wind path, and heat is taken away, and the temperature that wind path is got back to generator inner chamber wind in making reduces, and circulated air makes the temperature rise of motor controlled.Because the interior wind path of cooler itself is not with blower fan, circulated air is achieved by the impeller of two ends of rotor, and the length dimension of rotor must be considered impeller can be installed when generator designs, and the entire length size of generator is lengthened, volume increases, and makes the whole mobile inconvenience of cooler.The pipe of rectangular arranged is big to the resistance of wind in addition, and the local area easily produces the very low phenomenon of wind speed, forms the dead angle, influences the effect of heat exchange.Outer wind path adopts single blower fan, and the suffered pressure in tube sheet surface does not wait, and intermediate pressure is big, and all round pressure is little, and the distinguished and admirable speed that flows through the heat exchange pipe does not wait, and makes the weak effect of the heat exchange pipe heat exchange that is distributed in all round.
Summary of the invention
It is little to the purpose of this invention is to provide a kind of volume, good effect of heat exchange, reliability height, cooler of wind power generator easy for installation.
The present invention includes exogenous wind transportation work style machine, ventilating cabinet, tube sheet, M shape heat exchanger tube, wind collecting unit, go out, air intake vent, heat exchanger tube, tube sheet, dividing plate have been formed the core body of cooler, ventilating cabinet, cover plate have formed interior wind path with the core body of cooler; Dividing plate is separated into three part air ducts with the core body of cooler, interior wind path blower fan is extracted hot blast out from wind power generator middle part air outlet, through the middle air channel of subcooler and air channel, both sides with outside wind path force carry out air heat exchange after, send cool breeze back to motor internal from wind power generator both sides air intake vent, form the inner loop of wind, it is characterized in that being installed on the cover board by wind path blower fan in forming with the cover plate of molded dish type motor mount, by centrifugal blower and motor on this ventilating cabinet, cover plate and ventilating cabinet adopt and push and plug fastening mounting means.
Have spiral case on the ventilating cabinet half, also have half spiral case on the cover plate, half spiral case on wind collecting unit, the ventilating cabinet and half spiral case on the cover plate have formed the volute casing of centrifugal blower together, and air intake vent and the wind collecting unit at the interior wind path centrifugal blower fan blade wheel place after the installation join.
Because the heat exchanger tube that has adopted M shape to arrange has reduced interior wind path windage, flow velocity is even everywhere to make hot blast through heat exchanger tube, take full advantage of heat exchange area, outer wind path adopts two blower fan structures, and the tube sheet surface is subjected to uniform blast, the wind speed that flows through heat exchanger tube is even, good effect of heat exchange.Interior wind path carries blower fan structure, removes from when making the wind power generator design and considers two ends of rotor installation impeller, makes things convenient for design of electrical motor, and the volume of generator can reduce, and saves the space in cabin.Have molded dish type motor mount on the cover plate, interior wind path blower fan is installed on the cover board, and cover plate pushes and plugs fastening mounting means together with blower fan and ventilating cabinet employing, installs very convenient.Owing to have molded dish type motor mount on the cover plate, reduced the height of motor, the whole height of cooler is reduced, be convenient to cooler and in the cabin, move operation.
