Embodiment
Further specify below in conjunction with the embodiment of accompanying drawing the utility model.
Like Fig. 1, shown in Figure 2, the utility model comprises stator core 1 and is wound on the stator winding 2 on the stator core 1, and cooling sandwith layer 5 is arranged in permanent-magnetic wind driven generator stator core 1 disk body, and cooling sandwith layer 5 tops are provided with water inlet 3 and delivery port 4.Coolant flow channel 6 is located at cooling sandwith layer 5 inside, and coolant flow channel 6 is being double-spiral structure in the radial direction, and connects with one section bend pipe 8 near rotating shaft 7 places at disk, guarantees that current can turn back to delivery port 4 places of cooling structure along coolant flow channel 6 adverse currents.Coolant flow channel 6 can be processed or constituted by in cooling sandwith layer 5, being processed into groove as shown in Figure 2 by copper pipe in the utility model.Like Fig. 3, shown in Figure 4, the cross section of its further groove can be that circle also can be a rectangle.In order to guarantee radiation effect of motor, cooling sandwith layer 5 contains the air gap place and must use the heat-conducting glue of good heat conductivity to fill.In addition, the position of water inlet 3 and delivery port 4 is all in the same side of cooling sandwith layer 5, and staggered with stator winding 2.
The characteristics of the type of flow of the double-spiral structure water channel of the utility model are; After cooling water gets into coolant flow channel 6 from water inlet 3; Flow in a clockwise direction along coolant flow channel 6, when water flows near rotating shaft 7 places, through a bend pipe 8; Counterclockwise to flow out delivery port 4 through coolant flow channel 6, the water (flow) direction of wherein adjacent two coolant flow channels 6 is opposite again for current.
The water inlet 3 of the utility model and delivery port 4 be all on the surface of cooling sandwith layer 5, and water inlet 3, delivery port 4 link to each other with external cooler, guaranteed that cooling water carries out lowering the temperature after the heat exchange.Through water pump pressure is provided, makes cooling water pass through double helix coolant flow channel 6, finally get back to delivery port 4 and form the airtight water cooling circulatory system by water inlet 3.
Above-described only is the preferred implementation of the utility model, and the utility model is not limited to above embodiment.Be appreciated that other improvement and variation that those skilled in the art directly derive or associate under the prerequisite of the basic design that does not break away from the utility model, all should think to be included within the protection range of the utility model.
