AI Technical Summary

Benefits of technology

The present disclosure aims to provide an impeller and fan that can effectively dissipate heat and reduce noise caused by the blades. The impeller includes a wheel hub and multiple blades, which are connected to the hub through their roots. The blades have different lengths and angles with the hub, and their centroid is located at the impeller's axis center. This design helps to decrease noise and increase user satisfaction during heat dissipation.

Problems solved by technology

Moreover, to decrease the generated noise and the abnormal sound as the fan rotates is also a very important issue.
If the rotating heat-dissipating fan generates laud noise, abnormal sound and wind noise, the user may be affected by these noises and sound and feel uncomfortable.

Embodiment Construction

[0033]The present disclosure 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.

[0034]FIG. 1A is a schematic diagram of a fan according to an embodiment of the disclosure, FIG. 1B is a schematic diagram of an impeller according to an embodiment of the disclosure, and FIGS. 1C and 1D are top views of the impeller of FIG. 1B. To be noted, the lengths and shapes of the blades and the impeller 1 of FIGS. 1A to 1D are for illustrations only, and they can be modified based on the environment and the heat source of the target electronic device.

[0035]As shown in FIG. 1A, the impeller 1 is configured in a heat-dissipating fan. The fan can be applied to dissipate heat of any electronic device such as, for example but not limited to, a computer, power device, CPU, VGA, IC, mainboard, or lamp, which can generate a lot of heat. The fan can be configured to force the air flow...

Abstract

An impeller includes a wheel hub and a plurality of blades. The blade has a blade root, and the blade connects to the wheel hub through the blade root. The blades have different lengths. Each blade has an included angle between the blade root and the wheel hub, and the included angles of the blades are different. A centroid of the blades is located at an axis center of the impeller. The impeller is further configured with a blade reinforcement structure.

Description

CROSS REFERENCE TO RELATED APPLICATIONS[0001]This Non-provisional application claims priority under 35 U.S.C. § 119(a) on Patent Application No(s). 201720192846.9 filed in People's Republic of China on Mar. 1, 2017, the entire contents of which are hereby incorporated by reference.BACKGROUNDTechnology Field[0002]This disclosure relates to an impeller and, in particular, to an impeller having blades with different lengths and included angles.Description of Related Art[0003]The heat dissipation device has been widely applied in various electronic devices. In particular, the heat-dissipating fan has low cost, high heat-dissipating effect, and high reliability, so it is one of the popular heat dissipating devices for various systems.[0004]In order to design a proper heat-dissipating fan, the provided air quantity, air pressure and / or rotation speed must satisfy the requirements. Moreover, to decrease the generated noise and the abnormal sound as the fan rotates is also a very important ...
