COOLING SYSTEM OF BRAKING DISC Russian patent published in 2017 - IPC F16D65/12 F16D65/847 

FIELD: machine engineering.

SUBSTANCE: cooling a brake disc is formed as a disk body formed in the radial nonintersecting channels separated by partitions. Each radial channel consists of alternating converging and diffusing sections and channel section is designed as a circle, an ellipse or a quadrangle. The length of the diffuser is greater than or equal to the length of confuser site. This provides turbulence in the air flow channels of variable section.

EFFECT: cooling efficiency of the brake disc friction surfaces by passive convective heat transfer intensification, which reduces the maximum temperature of heating, protection from premature wear and increased service life of the brake disc.
