Benefits of technology

[0011] As mentioned above, the blower and the impeller structure of the invention have a connecting part for connecting the hub and the blades. Besides, the connecting part has a plurality of apertures formed by, for example, an aperture-making process. Thus, the balance-free objective can be achieved according to the apertures. Comparing with the prior art, the blower and impeller structure of the invention can achieve balance-free without the specific additional balance process, the conventional modification of mold. Therefore, the manufacturer can produce the blower and impeller structure of balance-free much easier. Accordingly, the manufacturing cost can be reduced so as to increase the marketing competitiveness of the products.

Problems solved by technology

The electrical component may generate heat and have decreased performance as the temperature rising.
The balance-free demand may not be achieved.
However, the modification of the mold is not easy due to the design of the conventional impeller structure.

Embodiment Construction

[0016] The present invention will be apparent from the following detailed description, which proceeds with reference to the accompanying drawings, wherein the same references relate to the same elements.

[0017] With reference to FIG. 2, a fan 2 according to a preferred embodiment of the invention comprises a driving device 21 and an impeller structure 23. The driving device 21 drives the impeller structure 23, so that an air flow is induced by the rotation of the impeller structure 23. In the embodiment, the fan 2 is a centrifugal fan or a blower, and the driving device 21 is a motor.

[0018] Please refer to FIGS. 3A to 3E for illustrating the detailed structure of the impeller structure 23. As shown in FIGS. 3A to 3C, the impeller structure 23 includes a hub 231, a connecting part 233, and a plurality of blades 235. In this embodiment, the connecting part 233 is disposed around the hub and connects to the hub 231. The blades 235 are disposed at the periphery of the connecting part 2...

Abstract

A blower includes a driving device and an impeller structure having a hub, a connecting part, and a plurality of blades. The driving device connects to and drives the hub. The connecting part is disposed around the hub and has a plurality of apertures. The blades are disposed at the periphery of the connecting part.

Description

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...
