Benefits of technology

The patent describes a high-speed blower with reduced noise. It includes a fan blade assembly with a cylinder, fan blades, and damping ribs. The damping ribs are placed between the fan blades to improve their structure and act as a vibration reducer for the fan blades when the blower operates at high-speed. The technical effect of this design is to create a more efficient and effective blower that produces less noise and vibration.

Problems solved by technology

Electronic devices such as central processing units (CPUs) frequently generate large amounts of heat during normal operation, which can destabilize operation of the electronic device and possibly cause damage.
The blower works at high speed to provide greater airflow, however, with greater speed comes greater noise.

Embodiment Construction

[0010]Referring to FIG. 1 and FIG. 2, a blower in accordance with a preferred embodiment of the present invention includes a fan blade assembly 100, a rotor 200, a stator 300, and a scroll housing 400. The fan blade assembly 100 includes a cylinder 110, an annular upper ring 120, an annular lower outer ring 130, an annular lower inner ring 140, a plurality of spaced fan blades 150, and damping ribs 160. The cylinder 110 is fixed to and surrounding the rotor 200. The fan blades 150 are arranged along a circumferential face, which surrounds and spaces the cylinder 110. The upper ring 120 connects with upper ends of the fan blades 150. The lower outer ring 130 connects with one side of lower ends of the fan blades 150. The lower inner ring 140 interconnects an opposite side of the lower ends of the fan blades 150 with the cylinder 110. The damping ribs 160 are set between each two adjacent fan blades 150 and arranged at a circle concentric with the cylinder 110. Adjacent two damping ri...

Abstract

A blower includes a fan blade assembly. The fan blade assembly includes a cylinder, fan blades, and damping ribs. The fan blades are fixed by an upper ring, a lower outer ring, and a lower inner ring. The cylinder is surrounded by the fan blades and coupled to the lower inner ring. The damping ribs are set between each two adjacent fan blades for enhancing structural integrity of the fan blade assembly thereby acting as a vibration damper of the fan blades when the blower operates at high-speed.

Description

FIELD OF THE INVENTION[0001]The present invention relates to a blower, and particularly to a blower for dissipating heat from electronic devices.DESCRIPTION OF RELATED ART[0002]Electronic devices such as central processing units (CPUs) frequently generate large amounts of heat during normal operation, which can destabilize operation of the electronic device and possibly cause damage. Oftentimes, a heat dissipation assembly is used to dissipate heat from the electronic device. The heat dissipation assembly frequently comprises a fan facilitating removal of heat from the electronic device.[0003]As computer technology continues to advance, the electronic devices of computers are being made to provide faster operational speeds and greater functional capabilities, which cause more heat to be generated. Therefore, high-speed blowers are used to dissipate the generated heat instead of ordinary fans. FIG. 3 shows a conventional blower. The blower includes a fan blade assembly 10, a rotor 20...
