Phase change material, air cooling and heat pipe coupled automobile brake disc heat dissipation system

The invention relates to a phase change material, air cooling and heat pipe coupled automobile brake disc heat dissipation system, which comprises a heat pipe, a cooling section of the heat pipe is arranged at an air inlet of a brake disc and adopts a snakelike design, a Tesla valve is arranged in the heat pipe, and the heat pipe is embedded in the brake disc; the metal pipe is arranged between the two layers of heat pipes, a phase change material is packaged in the metal pipe, the metal pipe and the evaporation section of the heat pipe are placed in a high-temperature area when the brake disc brakes, and the metal pipe is arranged between the upper disc piece and the lower disc piece; the radiating ribs are arranged between the upper disc and the lower disc and are used for supporting the upper disc and the lower disc; and the metal tube passes through the heat dissipation fins. The surface heat generated by braking of the automobile brake disc can be rapidly absorbed, meanwhile, heat of the most-heat-genera
