Description
- 1. Field of the Invention
- 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.
- 2. Description of the Related Art
- 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 processor.
- In order to keep a high-efficiency heat dissipation function, the heat dissipation unit has inevitably become larger and larger and heavier and heavier. 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.

FIG. 1 , which is a perspective assembled view of aconventional fan module 1. Thefan module 1 includes acentrifugal fan 10, aheat pipe 11 and aheat dissipation unit 12. Thecentrifugal fan 10 serves to drive air to flow so as to carry away the heat of theheat dissipation unit 12 and lower the temperature. The performance of thefan module 1 is determined by the wind pressure and air volume of thecentrifugal fan 10 and the heat exchange area of the heat dissipation unit. The larger the heat exchange area of theheat dissipation unit 12 is, for example, the longer the radiating fin is, the better the heat dissipation effect of theheat dissipation unit 12 is. 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. - In order to meet the requirements for lightweight, slimness and miniaturization, the respective components are as minified as possible. Therefore, the centrifugal fan is miniaturized. 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.
- According to the above, the conventional fan module has the following shortcomings:
- 1. The volume is larger.
- 2. The blades tend to deflect in rotation to cause unstable operation.
- It is therefore a primary object of the present invention to provide a swing fan structure, which has a greatly minified volume.
- It is a further object of the present invention to provide the above swing fan structure, which overcomes the shortcoming of unstable operation of the conventional fan caused by deflection of the blades in rotation.
- To achieve the above and other objects, the swing fan structure of the present invention includes a main body and multiple blades. The main body has an upper face and a lower face opposite to the upper 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. Each blade has a locating section disposed on the upper face and a first end extending from the locating section along the short side of the main body. The blades define therebetween a flow way. The blades are drivable by the main body to reciprocally move along the long side.
- 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 and the specific aerodynamic property of the wing-shaped configuration, the airflow around the first ends of the blades are changed to create an air volume through the flow ways. Accordingly, the swing fan structure can be used instead of the conventional fan to minimize the volume of the fan. Also, the swing fan structure overcomes the shortcoming of unstable operation of the conventional fan caused by deflection of the blades in rotation.
