Heat dissipation hole of a disk

Abstract

1. The name of the design product: the heat dissipation hole of the disc. 2. The use of the design product: the design product is a disc for vehicle brake, and the local use is the heat dissipation hole of the disc. 3. The design points of the design product: the shape. 4. The picture or photo that can best show the design points: the perspective view 1. 5. Other circumstances that need to be explained: the dotted line in the drawing is the part that is not claimed by the design; the perspective view 2 is a perspective view from another angle; the A-A sectional view is a sectional view taken along the line A-A in the front view, which is used to illustrate the depth of the arrow-shaped heat dissipation hole of the design; the B-B sectional view is a sectional view taken along the line B-B in the left view, which is used to illustrate the shape of the arrow-shaped heat dissipation hole of the design; the use state reference drawing is used to illustrate that the outer periphery of the disc is an 8-tooth structure when the design is implemented.
