[0002] Automobile brakes are the braking devices of automobiles. Brakes used in automobiles are almost all friction type, which can be divided into two categories: drum type and disc type. The rotating element in the friction pair of drum brakes is the brake drum, which has a connection hole on the mounting surface. When the automobile brakes, the friction between the friction pad and the inner wall of the brake drum forms a braking torque to achieve the purpose of braking the automobile. When the automobile brakes, the friction between the friction pad and the inner wall of the brake disc will generate a lot of heat, but the existing brake drum generally dissipates heat through air convection or automatically dissipates heat, resulting in poor heat dissipation effect. Once a long-term emergency brake is encountered, it is easy to cause the brake system to overheat and be damaged, seriously affecting the service life of the brake drum. Summary of the invention
