Description

[Detailed description of the invention]

[0001]

[Technical field to which the invention belongs]

 The present invention relates to a fan guide device for a notebook computer, and more particularly to a fan guide device for a notebook computer that can increase the air flow rate and improve the heat radiation effect.

[0002]

[Prior art]

 Generally, computers are electronic information products that are highly needed by modern people. Notebook computers have characteristics that are convenient to carry, such as small volume, thinness, and light weight, so that their share in computer sales is increasing.

However, since the conventional notebook computer is greatly limited in space and thickness, it has been necessary to solve the heat dissipation problem using a fan.

FIG. 1 is a perspective view showing a fan 10 of such a conventional notebook computer.

In FIG. 1, a fan 10 of a conventional notebook computer has an air inlet 11 on an upper surface and an air outlet 12 on one side.

FIG. 2 is a cross-sectional view when the fan 10 is provided on a main board in a notebook computer.

In FIG. 2, the notebook computer 100 incorporates a computer radiating fan 10 on an internal air passage 20, and introduces hot air from an air inlet 11 of the air passage 20 by operating the fan 10. Then, the hot air is led out of the outlet 12 to complete the heat radiation work.

Here, the main body of the fan 10 has a certain thickness, and forms a right angle with the wind path 20 when incorporated into the computer 100. For this reason, when the wind is guided by the operation of the fan 10, the three side ends (excluding the vent) of the fan 10 push back the wind to form a turbulent flow, and the wind is not discharged smoothly.

When the fan 10 operates, wind is introduced into the air inlet 11 from the air path and is led out from the air outlet 12. A part of the derived wind is sucked and circulated again by the wind absorption generated by the operation of the splash of the fan 10, so that the efficiency of the radiating fan 10 is reduced.

Due to such a cause, the intake by the fan 10 of the conventional computer 100 has not been smooth. Therefore, the airway had to be enlarged to make the air flow smooth. However, increasing the size of the airway causes a problem that the volume and thickness of the notebook computer 100 also increase.

[0011]

[Problems to be solved by the invention]

 In the conventional technology described above, the three side edges of the fan push back the wind force to form turbulence, and the fan intake is not smooth. Correspondingly, the wind path had to be enlarged to make the air flow smooth. However, enlarging the airway creates the problem of increasing the volume and thickness of the notebook computer.

The present invention has been made in view of the above circumstances, and an object of the present invention is to provide a notebook-type computer fan guide device that can reduce the wind pressure loss and increase the gas flow rate. Aim.

[0013]

[Means for Solving the Problems]

 In order to achieve the above object, the fan flow guiding device for a notebook computer according to claim 1 is provided with a fan for a notebook computer, which has a fan and a fan, respectively. A flow guiding device for guiding a flow, wherein a smooth curved air guiding body is provided on three sides outside the outer circumferential edge of the fan, the air guiding body being formed in a shape surrounding the outer peripheral edge of the fan, and the wind guiding body uses the air guiding body. Is smoothly introduced into the air inlet of the fan, and the other side is extended above the side of the air outlet of the fan to form a windproof portion, and the wind guided by the air outlet of the fan by the windproof portion. Preventing the diverted flow, smoothing the flow of the wind, increasing the flow rate, reducing the loss of wind pressure, improving the heat dissipation effect of the entire notebook computer, and increasing the thickness of the notebook computer And wherein the reducing.

According to such a configuration, when the flow guide device is incorporated into the outer peripheral edge of the fan of the computer, the wind can be smoothly introduced from the fluid guide into the fan of the computer quickly. There is no blind spot in the flow of air, and the installation of a windbreak prevents the air exhausted by the computer fan from flowing in the opposite direction. The diversion device acts to reduce the resistance of the fluid from entering the computer fan and increase the flow of air to enhance the heat dissipation of the notebook computer. In addition, since the material of the flow guide device is plastic, it has an effect of absorbing vibration and preventing noise.

FIG. 5 is a cross-sectional view when the flow guide device and the fan are provided on a main board in a notebook computer.

In FIG. 3, the flow guide device 3 of the notebook type fan according to this embodiment is made of a plastic material and is mainly formed by a combination of the wind guide 30 and the windbreak part 40.

The flow guiding device 3 has a pedestal shape, and has a space 31 at the center thereof, and the fan 1 is installed therein. A curved air guide 30 is provided on three sides of the pedestal, and a windproof part 40 extending upward is provided on the other side.

In FIG. 4, at the time of assembling, the flow guide device 3 is incorporated into the outer peripheral edge of the fan 1, and the windproof portion 40 of the flow guide device 3 and the air outlet 12 of the fan 1 correspond to each other.

With such a structure, the flow guiding device 3 guides the wind that is sucked and blown out by the air inlet 11 and the air outlet 12 of the fan 1 of the notebook computer, respectively.

The flow guiding device 3 is formed in a shape surrounding the outer peripheral edge of the fan 1, and has a smooth curved air guide 30 on three sides outside the outer peripheral edge of the fan 1.

The windshield 40 which is guided outside the mold computer 90 and on the air outlet 12 prevents circulation of the wind to be guided. After this, the wind to be led is sucked again from the outside by the wind force generated by the operation of the fan 1.

According to the flow guide device 3 of the present embodiment, when the fluid caused by the wind flows through different cross sections, the air guide body 30 having a smooth curved surface is used to smoothly flow the fluid and to prevent the fluid from flowing when flowing. The pressure loss can be reduced while increasing the flow rate. By using the windbreak unit 40 to prevent the fluid from circulating, the heat radiation effect of the heat radiation fan of the notebook computer is improved. Thus, the thickness of the notebook computer can be reduced.

The material of the flow guide device 3 is plastic, and when combined with the outer peripheral edge of the fan, has an effect of absorbing vibration and reducing noise. Therefore, the industrial use value is high.

As described above, the present invention has been disclosed by the preferred embodiments shown in FIG. 3 and FIG. 5, but this embodiment is not intended to limit the present invention, and is not limited to those skilled in the art. As can be easily understood, appropriate changes and modifications can naturally be made within the scope of the technical concept of the present invention.Therefore, by directly combining the diversion device with the cover of the fan, It is also possible to directly change the cover of the fan to the state shown in FIG. 4, and the scope of protection of the utility model must be determined based on the claims and the equivalent area.
