Embodiment Construction
[0037] The present invention will be further described below in conjunction with the accompanying drawings and specific embodiments.
[0038] Such as figure 1 As shown, a high-efficiency heat dissipation system for the magnetic pole coil of a hydro-generator includes a stator 1, a rotor 2 rotatably arranged in the stator, and a cooling and heat dissipation system (not shown in the figure) for cooling and driving the cooling air, such as figure 2 As shown, the rotor includes a middle shaft 23, a peripheral yoke 24, a bracket 25 for connecting the shaft and the yoke, a number of magnetic poles arranged around the yoke, the magnetic poles include an iron core 26, and a Several layers of rectangular frame-shaped copper bars 27. In order to facilitate the heat dissipation and cooling of the rotor and stator, such as image 3 As shown, we need to respectively set several radial ventilation holes 241 arranged at intervals along the axial direction on the yoke, the iron core and th...
