Heat dissipation hole of a disk

Abstract

1. The name of the design product: the heat dissipation hole of a disc. 2. The use of the design product: the design product is a disc for a vehicle; the partial use is the heat dissipation hole of the disc. 3. The design points of the design product: in shape. 4. The picture or photograph that best shows the design points: Fig. 1 is a perspective view. 5. Other circumstances or explanations: in each view, the part claimed is shown in solid line and the part not claimed is shown in dotted line. Fig. 2 is a perspective view from another angle. Fig. A-A is a sectional view taken along the line A-A in the front view, showing the depth of the two shorter arc-shaped holes of the design. Fig. B-B is a sectional view taken along the line B-B in the front view, showing the depth of the longer arc-shaped hole of the design. Fig. C-C is a sectional view taken along the line C-C in the left side view, showing the shape of the shorter arc-shaped hole and the longer arc-shaped hole of the design. Reference diagram in use: the outer periphery of the disc is an 8-tooth structure when the design is implemented.
