Wave Disc

Abstract

A wave-shaped disc includes a body surrounding an axis and centered on the axis, and a partition unit. The body comprises two spaced-apart disc walls along the axis, a peripheral wall connecting the outer periphery of the disc walls and defining an annular space with the disc walls, and a plurality of air inlets penetrating the peripheral wall. The peripheral wall has a plurality of spaced-apart centrifugal surfaces gradually moving away from the axis, and a plurality of windward surfaces. Each windward surface connects to two adjacent centrifugal surfaces. The air inlets communicate with the outside environment and the annular space. The partition unit includes a plurality of ribs formed between the disc walls, separating the annular space to form a plurality of flow channels. Each flow channel guides air entering from the corresponding air inlet toward the axis. This increases the airflow into the flow channels, thereby improving heat dissipation.

Claims

1. A wave-shaped disc, comprising: a body surrounding an axis and centered thereon, including two disc walls spaced apart along the axis, a peripheral wall connecting the outer periphery of the disc walls, and a plurality of air inlets penetrating the peripheral wall, the peripheral wall and the disc walls defining an inwardly opening annular space, and having a plurality of spaced-apart centrifugal surfaces gradually moving away from the axis, and a plurality of windward surfaces, each windward surface connecting two adjacent centrifugal surfaces, the air inlets communicating with the outside and the annular space; and a partition unit including a plurality of ribs formed between the disc walls, the ribs partitioning the annular space to form a plurality of flow channels, each flow channel for guiding air entering from a corresponding air inlet and discharging it toward the axis.

2. The wave disc as described in claim 1, wherein, These air inlets are distributed on the centrifugal surface and the windward surface.

3. The wave disc as described in claim 1, wherein, Each of the centrifugal surfaces has a proximal end adjacent to the axis and a distal end opposite to the proximal end and away from the axis. Each of the windward surfaces connects the proximal end of one of two adjacent centrifugal surfaces and the distal end of the other.

4. The wave disc as described in claim 1, wherein, Each of these centrifugal surfaces can be a curved surface, a plane, or a combination thereof.

5. The wave disc as described in claim 1 or 4, wherein, Each windward surface can be a curved surface, a flat surface, or a combination thereof.

6. The wave disc as described in claim 3, wherein, The main body also includes several heat dissipation units, each of which has several vents penetrating the walls of the disks, and these vents connect the corresponding flow channels to the outside.

7. The wave disc as described in claim 6, wherein, Each heat dissipation unit has vents arranged along a virtual arc, with the vents at both ends adjacent to the outer and inner peripheries of the corresponding disk walls.

8. The wave disc as described in claim 3, wherein, Each of the disk walls has several grooves formed on its outer surface.

9. The wave disc as described in claim 8, wherein, Each of these grooves extends along a virtual arc, with its two ends adjacent to the outer and inner peripheries of the corresponding disk walls.

10. The wave disc as claimed in claim 1 further includes a connecting unit comprising a plurality of mounting portions connected to the inner periphery of one of the disc walls.

11. The wave disc as described in claim 1, wherein, Each rib extends along a virtual arc and defines several channels, each channel connecting two adjacent flow channels.
