Fan capable of raising static pressure and its fan frame structure

The present invention relates to a fan and its frame structure, in particular to a fan and its frame structure capable of raising static pressure.

With the advancement of technology, the functions of computers and other 3C products are becoming more and more diversified, and the operating efficiency is getting higher and higher, so that the internal electronic components generate more heat, so most of the electronic components require heat dissipation devices. To dissipate heat, to prevent the high temperature of electronic components from affecting performance and stability during operation. Among them, a cooling fan is a common heat sink.

However, generally existing fans often have problems such as inconcentration of air output and insufficient air pressure, which leads to poor heat dissipation efficiency and cannot effectively dissipate the densely arranged electronic component areas or other places with high heat accumulation. In order to improve static Pressure and wind speed can be used to enhance the heat dissipation effect. Only by increasing the speed, it will cause excessive power consumption and excessive noise.

In view of this, the creator of the new type has focused on researching and cooperating with the application of theories in order to solve the above problems in order to solve the above problems, which has become the goal of the new type of creator's improvement.

Each vane includes a lower blade and an upper blade bent and extended from the lower blade. A first angle is formed between the upper surface of the lower blade and the axis. The upper surface of the upper blade and the axis A second included angle is formed therebetween, wherein the angle of the second included angle is greater than the angle of the first included angle.

In order to achieve the above objective, the present invention provides a fan capable of raising static pressure, which includes a fan frame structure and a fan wheel. The fan frame structure includes a frame, a bearing seat and a plurality of stationary blades, and the bearing seat has an axis parallel. Set in the frame body, each stationary blade system is respectively connected to the frame body and the bearing seat and arranged at intervals. Each stationary blade includes a lower blade and an upper blade bent and extended from the lower blade. A space is formed between the upper surface of the lower blade and the axis. In the first included angle, a second included angle is formed between the upper surface of the upper blade and the axis, wherein the second included angle is greater than the first included angle; the fan wheel includes a hub and a plurality of blades extending from the outer periphery of the hub.

The new model also has the following effects: the upper blade is configured to oscillate relative to the lower blade, so that the wind from each stationary blade is concentrated and the wind pressure is strong.

The detailed description and technical content of the present invention will be described as follows in conjunction with the drawings. However, the drawings are only for illustrative purposes and are not intended to limit the present invention.

The present invention provides a fan frame structure 10 capable of raising static pressure. Please refer to FIGS. 1 to 5. It includes a frame 11, a bearing seat 12 and a plurality of static blades 13.

The frame 11 can be formed by plastic injection molding. It has an air inlet 111, an air outlet 112 and an internal flow channel 113 for airflow. The air inlet 111 and the air outlet 112 are respectively arranged on the top of the frame 11 And the bottom, and the internal flow channel 113 is connected to the air inlet 111 and the air outlet 112, so that air enters from the air inlet 111 and flows out from the air outlet 112 after passing through the internal flow channel. The frame 11 is also provided with a plurality of fixing holes 114, each The fixing holes 114 are respectively locked by a screw element to fix the fan frame structure 10.

The supporting base 12 can be formed by integral molding of plastic injection, and has an axis 121. The supporting base 12 is disposed in the frame 11 and located on the air outlet 112.

Each stator blade 13 can be formed by integral plastic injection molding, which is connected to the frame body 11 and the bearing seat 12 and arranged at intervals. Each stator blade 13 includes a lower blade 131 and an upper blade 132 bent and extended from the lower blade 131. A first included angle 14 is formed between the upper surface of the lower blade 131 and the axis 121, and a second included angle 15 is formed between the upper surface of the upper blade 132 and the axis 121, wherein the angle of the second included angle 15 is greater than the angle of the first included angle 14 , And the upper surface of the upper blade 132 is a curved surface, and the second included angle 15 is formed by the intersection of the tangent 1321 of the curved surface and the axis 121.

To further illustrate, the angle difference between the second included angle 15 and the first included angle 14 can be any angle between 5 and 45 degrees, and the first included angle 14 can be any angle between 5 and 25 degrees.

Wherein, preferably, the angle difference between the second included angle 15 and the first included angle 14 can be any angle between 15 and 35 degrees, and the first included angle 14 can be any angle between 10 and 20 degrees.

Furthermore, most preferably, the angle difference between the second included angle 15 and the first included angle 14 is 25 degrees, and the first included angle 14 is 15 degrees.

To further explain, when the angle difference between the second included angle 15 and the first included angle 14 is greater than 45 degrees, the air flow generated by the air flow out of the frame 11 will be reduced, and when the second included angle 15 and the first included angle 14 are When the difference is less than 5 degrees, the lifting effect of static pressure is not obvious. Therefore, when the angle difference between the second included angle 15 and the first included angle 14 is any angle of 5 to 45 degrees, a certain static pressure can be raised and self-frame can be avoided. The air volume generated by the air flow out of the body 11 is too small.

Moreover, when the angle of the first included angle 14 is greater than 25 degrees, the air flow out of the frame 11 will not be concentrated; and when the angle of the first included angle 14 is less than 5 degrees, the air flow out of the frame 11 will be caused The generated air volume is too small, so the stator blade 13 with any angle from 5 to 25 degrees as the first included angle 14 can prevent the outflow of the air from being inconcentrated and avoid the generated air volume from being too small.

Please refer to Figure 6, the present invention also provides a fan 1 capable of raising static pressure, which includes a fan wheel 20 and a fan frame structure 10 as described above. The fan wheel 20 can be formed by plastic injection molding. It includes a hub 21 and a plurality of fan blades 22 extending from the outer periphery of the hub 21, and the fan wheel 20 is rotatably arranged in the frame 11 and connected to the supporting portion 12.

In summary, this new model has industrial applicability, novelty and advancement, and fully meets the requirements of a patent application. The application is filed in accordance with the Patent Law. Of course, the present invention can also have various other embodiments. Without departing from the spirit and essence of the present invention, those skilled in the art can evolve various corresponding changes and modifications according to the present invention, but these corresponding changes And deformation should belong to the protection scope of the patent applied for this new model.
