BACKGROUND OF THE INVENTION
[0001] 1. Field of Invention
[0002] The invention relates to a blower and an impeller structure thereof and, in particular, to a centrifugal blower and an impeller structure thereof.
[0003] 2. Related Art
[0004] In the conventional electrical system, the electrical component, such as a CPU, is usually provided. The electrical component may generate heat and have decreased performance as the temperature rising. In such a case, to maintain the acceptable performance of the electrical component, the generated heat must be removed as soon as fast. To achieve this objective, a blower is usually adopted to dissipate heat quickly.
[0005] The conventional blower commonly includes a motor and an impeller structure. As shown in FIG. 1, a conventional impeller structure 1 includes a hub 11, a ring portion 13 and a plurality of blades 15. Herein, the ring portion 13 is disposed annularly around the hub 11, and the blades 15 are connected to the ring portion 13. Since...
