Abstract

The invention discloses a heat-pipe type automobile brake disc cooling device. The heat-pipe type automobile brake disc cooling device comprises a brake disc, a heat-pipe evaporation section, radiating fins and a heat-pipe condensation section. The interior of the brake disc is hollow and the cross section of the hollow part is in an L shape. The heat-pipe evaporation section and the heat-pipe condensation section form an L shape. An L-shaped interior cavity is filled with a working medium and sealed after being vacuumized. The radiating fins are welded to the exterior of the heat-pipe condensation section. When a vehicle is braked or braked for a long time, friction between a brake pad and the brake disc occurs and heat is generated; the heat passes through the working medium in a heating cavity of the brake disc and arrives at the condensation section after the working medium evaporates, and the heat is dissipated to the atmosphere through the radiating fins of the condensation section. Accordingly, the temperature of the brake disc is decreased, the braking heat fading phenomenon is reduced, and the traffic safety is improved.

Description

technical field [0001] The invention relates to a heat pipe type automobile brake disk cooling device, which uses the heat pipe principle to rapidly cool the brake disk and belongs to the technical field of automobile equipment. Background technique [0002] Braking is one of the most important parts of a car, and the quality of braking performance directly affects driving safety. When the car brakes for a long time, the temperature of the brake disc is very high. At night, you can even see the brake disc glow red. In this case, brake failure is very easy to occur. This situation is very dangerous when encountering continuous downhill on rugged mountain roads. Brake heat fade occurs even with daily service brake use. [0003] At present, in order to reduce the phenomenon of heat fading in vehicles, automobile brake manufacturers generally use hollow brake discs and drill holes in the brake discs to increase the heat dissipation area and reduce the phenomenon of heat fadin...
