[0012] Further, the height of the blade extending on the base is not less than 1 / 3 of the height of the base.

[0013] Further, the blade extends outward, and the width of the extension is not less than 1 / 2 of the radius of the base.

[0014] Further, the width of the blade is not less than 1.2 times the height of the blade.

[0015] The beneficial effects of the present application are as follows: the large-power motor cooling fan provided by the present application is integrally formed with the base and the support plate, thereby improving the strength of the fan base, and the blade is integrally formed with the base and the support plate, thereby realizing that the blade can extend outward on the surface of the support plate, improving the area and support strength of the blade, thereby improving the cooling efficiency in a limited space, and because the wind guide groove is added to improve the airflow speed, the cooling effect is further improved.
