Embodiment:
Below in conjunction with accompanying drawing the present invention is done and to describe in further detail:
As shown in Figure 1, the water-cooled wind-driven generator comprises that mainly stator, rotor, bearing portion group, labyrinth type water-cooled end cap, two-layer equation water jacket support 1, cooling water connect flexible pipe, inner shaft band centrifugal fan, slip ring carbon brush group.
As shown in Figure 2; Cooling water gets into drive end water-cooled end cap from front end housing 2 (drive end) water inlet; Behind the supercooling drive end bearing, flow out from the end cap delivery port; Get into the water inlet of generator two-layer equation water jacket support 1 behind the process connection flexible pipe, flow out from water jacket support delivery port 20 behind the cooling water process cooled electric generator rotor, get into rear end cap 3 (anti-drive end) water inlet behind the cooling water process connection flexible pipe; Cooling water flows out from the end cap delivery port behind the supercooling non-driven-end bearing, and whole water-flow chart has been accomplished the good heat radiating of generator stator-rotator and bearings at both ends.
Shown in Figure 3 is labyrinth type water-cooled end cover structure, and this structure mainly is made up of end cap body, water channel gusset, water inlet pipe, outlet pipe and water channel welded cover plate.This maze-type structure can be strengthened the turbulence intensity of water greatly, thus enhanced heat exchange, cooling bearing effectively.
Shown in Figure 4 is two-layer equation water jacket support 1 structure, and this structure is mainly by inner barrel 14, water inlet pipe, outlet pipe, water channel, water channel muscle, intermediate cylinder, air channel 18, support air channel muscle, outer cylinder body 16, footing, and hanger is formed.This main structure body is water channel and the air channel 18 that two-layer equation distributes: inner barrel 14 has constituted cooling-water duct with intermediate cylinder and water channel muscle, and intermediate cylinder and air channel muscle and outer cylinder body 16 have constituted cooling air channel 18.The heat that stator produces is taken away by the cooling water in the cooling water channel through heat conduction, and radiating effect is good.Welding one circle air channel muscle has significantly increased the heat convection area in the cooling air channel 18.The heat that rotor produces passes to cooling support air channel muscle 23 by circulating air and is finally taken away by the cooling water in the cooling water channel, has significantly reduced the temperature rise of rotor.
