Swing fan structure

Abstract

A swing fan structure includes a main body and multiple blades. The main body has an upper face and a lower face. The main body also has a long side and a short side. The blades are side by side disposed on the upper face of the main body in parallel to each other. The blades define therebetween a flow way. The blades are drivable by the main body to reciprocally move along the long side to create an air volume. The swing fan structure has a greatly minified volume. Also, the swing fan structure overcomes the shortcoming of unstable operation of the conventional fan caused by deflection of the blades in rotation.

Description

BACKGROUND OF THE INVENTION[0001]1. Field of the Invention[0002]The present invention relates generally to a swing fan structure, and more particularly to a swing fan structure, which has a greatly minified volume. Also, the swing fan structure overcomes the shortcoming of unstable operation of the conventional fan caused by deflection of the blades in rotation.[0003]2. Description of the Related Art[0004]Along with the continuous advance of electronic technologies and industries, the density of transistors of various chips (such as central processor and execution unit) has been more and more increased. This enables the central processor to process data at higher and higher speed. However, the power consumption and heat generated by the central processor have also become higher and higher. In order to keep the central processor stably operating, it has become an important topic how to develop high-efficiency heat dissipation unit for dissipating the heat generated by the central pro...

AI Technical Summary

Benefits of technology

The present invention is for a swing fan structure that has a small volume and solves the issue of unstable operation caused by blad deflection during rotation. The blades have a wing-shaped configuration that changes the airflow around their ends to create an air volume through flow ways. This results in a reduced fan volume and stable operation.

Problems solved by technology

However, the power consumption and heat generated by the central processor have also become higher and higher.

However, in design of electronic device such as laptop, tablet, intelligent mobile phone and intelligent handheld electronic device, the limitation of space is always a greatest bottleneck of the design process.

However, the increase of the length of the radiating fin will lead to excessively large total volume of the fan module.

This fails to meet the requirements for lightweight, slimness and miniaturization of the laptop.

However, due to the miniaturization of the volume, the blades of the centrifugal fan are very thin.

This will cause more vibrations and make louder noise.

1. The volume is larger.

2. The blades tend to deflect in rotation to cause unstable operation.
