Heat-dissipation structure of brake pad

A heat-dissipation structure of brake pad, adapted for being disposed on a caliper device wherein the caliper device includes a caliper body having a fixed-volume receiving room formed through the caliper body, the heat-dissipation structure of brake pad includes:

• a main plate, having a first face and an opposite second face, the main plate having a first heat-dissipation portion at a first end and a second heat-dissipation portion at a second end, the first heat-dissipation portion including a plurality of heat-dissipation pillars protruded from the first face, the second heat-dissipation portion including a plurality of protrusions protruded from at least one of the first face and the second face, the main plate having a brake pad on the second face, the brake pad being located between the first heat-dissipation portion and the second heat-dissipation portion, when the main plate is disposed on the caliper body, the main plate penetrates the receiving room, the first heat-dissipation portion and the second heat-dissipation portion are exposed outside the caliper body at two ends of the caliper body respectively, and the brake pad is received in the receiving room.
