Disk Brake Pad

VORTEX COOLING TECHNOLOGIES

Heat Removal 1: Conduction Oversized backing plate to give more mass and lager surface area to conduct heat away from the friction material

Heat Removal 2: Convection Protruding Pyramid fins section allow greater surface area in contact with wind increasing the heat transfer from the backing plate to the atmosphere

Heat Removal-3: Vortex Cooling “V” Fins speed up cooling, generating local vortexes in air –flow allowing constant replacement of heated contact air with passing cool air

  • Improved Performance: Meaning you can brake harder and longer
  • Reduced “Brake Fade”: Pads cool so quick compound doesn’t reach temperatures associated with fade
  • Reduced “Pump-Up”: Heat transferred away from the brake piston limits potential for brake fluid to expand or vaporize; improving safety
  • Improved Pad Life: Keeping the compound cool significantly improves pad life by as much as 3X
  • Reduce Noise: Due to lower pad/disk temperatures

PRIMUS : Heat Pipe Technology Pat. Pending

A Heat Pipe is a device that combines the principles of thermal conduction and phase transition. At the hot interface (brake pad friction material) liquid is heated by the thermally conductive aluminum pipe (backing) until it becomes a vapor. The vapor then travels along the pipe to the cooler interface (reservoir/radiator), located at the top of the backing, where it evaporates and becomes a liquid and by so doing releasing the latent heat. The liquid then returns, aided by gravity to the hot interface where the cycle is repeated.

Note the vapor pressure at the high temperature end is much higher than the liquid low pressure end resulting in rapid mass transfer. The molecular speed in a gas approaches the speed of sound which makes the heat transfer rates of heat pipes much higher than simply relying on thermal conduction alone.

Benefits:

  • Rapid cooling of brake pads, meaning you can brake harder and longer
  • Reduced “Brake Fade”, as the pads cool so quick compound doesn’t reach temperatures associated with fade
  • Reduced “Pump-Up”, transferring the heat away from the brake piston limits potential for brake fluid to expand or vaporize; improving safety
  • Improved Pad Life, keeping the compound cool significantly improves pad life as much as 3X
