Cooling back plate construction

This creation is about a kind of heat dissipation back plate structure, especially the double-layer hollow structure and the penetrating heat dissipation channel to increase the heat convection phenomenon, improve the heat dissipation speed, and maintain the good braking condition to heat the film. Backboard.

The steam locomotive is the most important transportation tool today. It has the advantages of fast driving speed and high maneuverability. With the development of steam locomotives, the sense of distance between the two places is shortened, and people's living circles are expanded. However, the steam locomotive is driving at high speed. In order to cope with various emergencies on the road, the most important safety mechanism is the brake mechanism that can stop the steam locomotive at any time.

The principle of steam locomotive braking is to use the film to clamp the brake disc, and the friction between the two can quickly convert the kinetic energy of the locomotive into heat dissipation, and stop the locomotive.

It can be seen from the above description that the disc and the order piece need to withstand extremely high friction force, thereby converting the kinetic energy of the high speed running of the steam locomotive into heat energy, which is bound to make the brake disc and the order piece need to withstand high temperature and may affect the braking. Safety, so in order to maintain good braking performance, high heat dissipation speed is an important characteristic that the brake disc and the order piece need.
