Heat dissipation plate

A heat dissipation plate, being adapted for a bicycle disc brake, the bicycle disc brake comprising two corresponding cases coupled together, two back panels, two brake linings, and a pin, the back panels, brake linings and pin being assembled between the cases, each of the back panels having a first surface and a second surface, the brake linings being respectively fixed on the first surfaces, each of the back panels being formed with an aperture, the pin penetrating through the apertures, the brake linings being located between the back panels, the heat dissipation plate comprising:

• a heat dissipator,
• two elastic plates, fixed under the heat dissipator, each of the elastic plates extending from a bottom of the heat dissipator so as to form with a connection section, an extension section, and two abutting sections, the connection section being fixed to the heat dissipator, the connection section extending vertically, the connection section being formed with a positioning hole, the positioning hole being adapted to be penetrated by the pin, the extension section laterally extending from two sides of a distal end of the connection section, the abutting sections respectively extending vertically from the extension section, the abutting sections being adapted to abut against the first surface of one of the back panels;
• wherein the elastic plates have an elastic tendency to depart from each other, so that the abutting sections abut against the back panels so as to separate the brake linings from each other;
• wherein the whole of the heat dissipator is located beyond the two cases, the connection sections gradually approach to each other from their respective distal ends toward the heat dissipator, and at least part of the bottom of the heat dissipator is continuously connected between the two elastic plates.
