[0039] Vehicle braking usually adopts disc brake system, when the vehicle has braking demand, the force assembly of brake caliper receives the pipeline pressure generated by brake controller, and the brake friction plate and brake disc are clamped under the action of normal pressure to generate braking torque, so as to achieve the preselected deceleration. In the process of friction braking, heat is generated in the friction pair, which is transferred to the brake disc and brake caliper through the paths of heat conduction, heat convection and heat radiation.

[0040] In the prior art, the heat dissipation mode of the brake disc usually adopts natural heat dissipation or air cooling heat dissipation. In the air cooling heat dissipation, a wind guide pipe is usually arranged on the vehicle body; the oncoming airflow of the vehicle is introduced into the vicinity of the center of the brake disc for heat dissipation.

[0041] After the vehicle is stopped or decelerated by braking, the vehicle experiences the braking process, and the brake disc is in the stage of urgently needing heat dissipation.
