Fig. 2 is a stereogram of the present invention.
[embodiment]
Describe the present invention below in conjunction with accompanying drawing:
As shown in the figure, the Large-scale Wind Turbines of generator and the shared water cooling method of gear-box, include pylon 1 and the main frame 2 that is installed in pylon 1 top and be connected the impeller 3 of main frame 2, described main frame 2 includes cabin 21 and is located at the gearbox 23 that is connected with impeller 3 in the cabin 21, the generator 22 that is connected with gearbox 23.Impeller 3 rotates and drives gearbox 23 rotations, and after process gearbox 23 carried out speedup, gearbox 23 output shafts just can drive generator 22 and generate electricity.
In order to realize that generator and gearbox adopt a cover water-cooling heat radiating system, present embodiment adopts following scheme: be provided with water/oil heat exchanger 4 on gearbox 23.In generator 22, be provided with water cycle heat dissipation pipeline 5.In cabin 21, be provided with the water pump water supply assembly 6 that supplies water to water/oil heat exchanger 4, water cycle heat dissipation pipeline 5.21 afterbodys are provided with water/air heat exchanger 7 in the cabin.Described water/air heat exchanger 7 is connected respectively on the outlet pipe of water/oil heat exchanger 4, water cycle heat dissipation pipeline 5 by inlet pipeline, make the water that has heat in water/oil heat exchanger 4 and the water cycle heat dissipation pipeline 5 enter into water/air heat exchanger 7, enter into water/air heat exchanger 7 again and dispel the heat.Water/air heat exchanger 7 is connected on the water pump water supply assembly 6 by rising pipe by the water after dispelling the heat again.
Its circuit route: provide cooling water to water/oil heat exchanger 4, water cycle heat dissipation pipeline 5 respectively by water pump water supply assembly 6 earlier, cooling water is taken away the heat in the gearbox 23 through behind water/oil heat exchanger 4.Behind the cooling water process water cycle heat dissipation pipeline 5, take away the heat in the generator 22.Afterwards, the water that comes out from water/oil heat exchanger 4 and from the required water/air heat exchanger 7 of water that water cycle heat dissipation pipeline 5 comes out.Dispel the heat through water/air heat exchanger 7, water/air heat exchanger 7 is back in the water pump water supply assembly 6 behind the water-cooled again, realizes heat absorption, heat radiation circulation.
