[0003] The patent with application number CN202321654011.2 discloses a brake disc with good heat dissipation performance, including a brake disc body, wherein the brake disc body includes a brake center disc, a brake disc, and a brake caliper.

A wear-resistant layer is provided on the surface of the brake disc to increase the friction coefficient of the brake disc, thereby improving the braking performance and wear resistance of the brake disc. A plurality of air guide blades are fixedly installed inside the brake disc, and a heat dissipation channel is formed between adjacent air guide blades. The air guide blades rotate at high speed to accelerate the air circulation in the heat dissipation channel, and the cold air is used to quickly dissipate heat, thereby reducing the temperature of the brake disc and improving the heat dissipation effect.
