Please refer to FIG. 1 to FIG. 3 , which shows a brake disc having a heat dissipation structure provided by the present invention, which comprises a substantially circular thin plate body 1 , wherein the plate body 1 is made of steel. The plate body 1 has a central portion 11 and a circumferential portion 12 surrounding the central portion 11. The annular portion 13 is formed between the central portion 11 and the circumferential portion 12, and the central portion is formed. 11 is connected to the circumferential portion 12 by a plurality of connecting arms 14, and the plurality of connecting arms 14 divide the interval 13 into a plurality of hollow chambers 15.

The central portion 11 is provided with a coupling hole 16 for coupling the axle of the vehicle tire (not shown); and the surrounding ring of the coupling hole 16 is provided with a plurality of mounting holes 17 for assisting the fixing of the axle.

The outer circumferential edge of the aforementioned circumferential portion 12 is substantially circular, and can be formed into various shapes according to functional or aesthetic requirements. A plurality of heat dissipation holes 121 are defined in the circumferential portion 12 to increase the area of the circumferential portion 12 in contact with the air, thereby improving heat dissipation efficiency.

Each of the connecting arms 14 extends from the inner periphery of the circumferential portion 12 and extends in a direction not pointing to the central position of the central portion 11 to be connected to the central portion 11, whereby the space 13 is formed with a plurality of hollows. Room 15. Further, in the present embodiment, the circumferential portion 12 projects a plurality of spines 122 at positions corresponding to the respective hollow chambers 15.

Further, in the present embodiment, the central portion 11, the circumferential portion 12, and the connecting arms 14 are integrally connected.

Furthermore, a heat dissipating member 2 is disposed in each of the hollow chambers 15 formed by the connecting arms 14 and the central portion 11 and the circumferential portion 12 for guiding the thermal energy of the plate body 1. Each of the heat dissipating members 2 is made of an aluminum alloy material and is fixed to the plate body 1 by heat fusion or forging; in detail, each of the heat dissipating members 2 is coated by heat fusion or forging in the hollow chamber 15 in which it is located. Outside the spine portion 122, the peripheral edge of each of the heat dissipating members 2 extends to cover the side edges of the connecting arm 14 and the circumferential portion 12, thereby enhancing the stability of the heat sink 2 and the plate body 1.

In addition, in the embodiment, each of the heat dissipating members 2 has a plurality of heat dissipating fins 22 extending toward the same side of the board body 1; wherein the heat dissipating fins 22 on the same heat dissipating member 2 are juxtaposed and parallel to each other. Extend the ground.

With the above structure, in addition to dissipating heat through the heat dissipation holes 121 in the circumferential portion 12, the present invention can increase the contact area with the air through the heat dissipating members 2 and the heat dissipation fins 22 provided thereon, thereby enhancing the contact area. Cooling efficiency. On the other hand, each of the heat dissipating members 2 is in a combined shape with the spine portion 122 in the hollow chamber 15 and covers the connecting arm 14 and the circumferential portion 12, except that the heat dissipating members 2 are more firmly coupled thereto. In addition to the plate body 1, the contact area between the heat dissipating members 2 and the plate body 1 is increased, thereby improving the conduction efficiency of the heat energy, so that the heat energy on the plate body 1 is quickly led to the heat dissipating members 2, and through the heat dissipating fins. 22 scatters, thus achieving the effect of maintaining brake performance.

However, the above description of the embodiments is merely illustrative of the present invention and is not intended to limit the present invention. Therefore, the replacement of equivalent elements should still be within the scope of the present invention.
