Abstract
A heat dissipation device includes a plurality of fins connected to each other. Each fin includes a first section with a first surface, a second section with a second surface parallel to the first surface, and a connecting portion. The connecting portion connects the first and second sections and extends along a normal direction thereof. An air passage is formed between the first section and the second section, so that air passes sequentially through the first surface, the air passage and the second surface.
Claims18
A heat dissipation fin, comprising:
- a first section having a first surface;
- a second section having a second surface parallel to the first surface, wherein the first surface and the second surface are at different levels;
- and
- a connecting portion connecting the first and the second sections, wherein an air passage is formed on the connecting portion and between the first section and the second section so that an air passes sequentially through the first section, the air passage and the second section.
