Benefits of technology

[0014]In the above swing fan structure, the locating sections of the blades are located on the upper face of the main body with the first ends of the blades extending along the short side of the main body. When a power member is turned on, the main body is driven by the power member to move along the long side. At this time, the blades are driven by the main body to reciprocally move. Due to the wing-shaped configuration of the blades an

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

Example

[0037]Please now refer to FIG. 7, which is a perspective assembled view of a fifth embodiment of the swing fan structure of the present invention. The fifth embodiment is partially identical to the first embodiment in component and relationship between the components and thus will not be repeatedly described hereinafter. The fifth embodiment is mainly different from the first embodiment in that the swing fan structure includes multiple main bodies 20 and multiple blades 21 disposed on the main bodies 20. The main bodies 20 are serially connected with each other to form a large-size swing fan structure. This can achieve the same effect as the above embodiments.

[0038]In conclusion, in comparison with the conventional fan structure, the present invention has the following advantages:

[0039]1. The volume of the fan structure is greatly reduced.

[0040]2. The shortcoming of unstable operation of the conventional fan structure caused by deflection of the blades in rotation is overcome.

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...
