[0018] Such as Figure 1~4 Shown: The present invention is a direct-drive wind generator with a special ventilation and cooling structure. The casing of the wind generator is provided with a rotor 6 and a stator base 3 that cooperate with each other. The front cover 9 of the casing corresponds to the non-driving end of the wind generator, and the rear cover 11 corresponds to the driving end of the wind generator.
[0019] The two sides of the outer circumferential surface of the stator frame 3 are respectively provided with a front side baffle 11 and a rear side baffle 12. The front side baffle 11 and the rear side baffle 12 are in an annular shape and are fixedly connected to the stator frame 3. On both sides of the outer circumferential surface, the height of the front side baffle 11 and the rear side baffle 12 is higher than the outer circumferential surface by a certain distance, so that a ring of annular groove body is formed near the outer circumferential surface of the sta...
