Turbo fan structure

This creation is about a cooling fan structure, especially a supercharged fan structure.

With the advancement of technology, the functions of 3C products such as computers are becoming more diverse, and the heat generated by the internal electronic components is also more impressive. If the temperature of electronic components is too high, the performance and stability during operation will be affected. Most electronic components require heat sinking to ensure proper operation of the electronic components. Among them, the cooling fan is a common heat sink, and in order to increase the heat dissipation area, the cooling fan is usually used in parallel arrays.

However, the installation space of the modern heat dissipating device is limited. Therefore, the above-mentioned plurality of fans are not easy to install the air-conducting and pressurized structure, which causes problems such as uneven airflow and insufficient wind pressure of the fans, which leads to poor heat dissipation efficiency and inability to provide intensive cooling. Arranged electronic component areas or other high heat accumulations for more efficient heat dissipation.

In view of this, the creator has made great efforts to solve the above problems by focusing on the above-mentioned prior art, and has devoted himself to the application of the theory, that is, the goal of the creator's improvement.

The purpose of the present invention is to provide a supercharged fan structure, which is formed by laminating a first fan blade group and a second blade group portion, and the stacking region can effectively increase the wind pressure and the air supply volume to achieve The booster fan structure has the advantages of improving heat dissipation efficiency, reducing noise, and reducing the combined space.

In order to achieve the above object, the present invention provides a supercharged fan structure including: at least one first fan having a first blade group; and at least one second fan having a second blade group, the first A portion of the blade group and a portion of the second blade group are stacked to form a laminated region.

The present invention also has the following effects: the first blade gradually reduces the thickness to form a first inclined surface, and the second blade gradually reduces the thickness to form a second inclined surface, the first inclined surface at each position of the laminated region and each second inclined The faces are generally equidistantly disposed such that the sum of the thicknesses of the first blade and the second blade stack is maintained at a thickness of about one blade to maintain the volume of the booster fan structure within a defined thickness range.

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

Referring to FIG. 1 to FIG. 3 , the present invention provides a booster fan structure. The booster fan structure 10 mainly includes one or a plurality of first fans 1 and one or a plurality of second fans 2 .

The first fan 1 has a first blade group 11 and a first hub 12, and the first blade group 11 includes a plurality of first blades 111 disposed around the periphery of the first hub 12, each of the first blades 111 having A first end 112, each of the first blades 111 tapers from the first hub 12 toward the first end 112 to form a first inclined surface 113.

The second fan 2 has a second blade group 21 and a second hub 22, and the second blade group 21 includes a plurality of second blades 211 disposed around the periphery of the second hub 22, each of the second blades 211 having A second end 212, each of the second blades 211 is gradually reduced in thickness from the second hub 22 toward the second end 212 to form a second inclined surface 213.

Wherein, a portion of the first blade group 11 and a portion of the second blade group 21 are stacked to form a layered area a, and the remaining portion of the first blade group 11 and the remaining portion of the second blade group 21 are not stacked. The first inclined surfaces 113 disposed at the stacked area a and the second inclined surfaces 213 are disposed to face each other upward and downward.

In addition, each of the first inclined surfaces 113 positioned in the layered region a and the second inclined surfaces 213 are disposed substantially equidistantly, that is, the first inclined surfaces 113 and the second inclined surfaces 213 are substantially equidistantly disposed. The sum of the thicknesses of the first blade 111 and the second blade 211 is maintained at a thickness of about one blade, and the total thickness of the layer a is prevented from being greater than the thickness of the first fan 1 or the second fan 2, so as to increase The volume of the fan structure 10 is maintained within a defined thickness range.

In addition, in the embodiment, the number of the first fans 1 is one, and the number of the second fans 2 is two, but not limited thereto, and the second fan 2 is disposed on the left and right sides of the first fan 1, The left and right sides of the first blade group 11 are respectively stacked with the two second blade groups 21, and the rotation direction of the first fan 1 is opposite to the rotation direction of the second fan 2.

Moreover, the arrangement of the first inclined faces 113 at the position of the laminated region a and the second inclined faces 213 substantially equidistantly disposed is only a preferred embodiment of the present invention, and is not intended to limit the present creation. Therefore, each of the first blades 111 can also maintain the same thickness from the first hub 12 toward the first end 112 without the first inclined surface 113, and each of the second blades 211 can also be from the second hub 22 toward the second The direction of the end 212 is maintained at the same thickness without the second inclined surface 213; or the first inclined surface 113 of the laminated area a and the second inclined surface 213 may be disposed at a non-equal distance, not in this embodiment. limit.

In addition, the second fan 2 of the present embodiment is disposed on the left side or the right side of the first fan 1, and is not limited to the embodiment. The second fan 2 can also be disposed on the upper side or the lower side of the first fan 1 according to actual conditions. .

As shown in FIG. 1 to FIG. 3, the combination of the present supercharging fan structure 10 utilizes a first fan group 1 having a first blade group 11; the second fan 2 has a second blade group 21, a first blade A part of the group 11 and a part of the second blade group 21 are stacked to form a laminated area a. Thereby, compared with the portion where the first blade group 11 and the second blade group 21 are not stacked, the layered area a can increase the wind pressure and the air supply amount, and the layered area a corresponds to the densely arranged electronic component area or the like. The high heat accumulation is configured to provide more air supply, so that the booster fan structure 10 has excellent heat dissipation efficiency.

In addition, a part of the first blade group 11 and a part of the second blade group 21 are stacked to form a layered area a, that is, the effect of locally increasing the wind pressure and the air supply amount can be achieved, and the air guiding supercharging structure does not need to be added. The booster fan structure 10 has the feature of reducing the combined space.

Furthermore, compared with the heat dissipating fan with the air guiding and supercharging structure, the wind pressure of the laminated area a is large, and the supercharging fan structure 10 has the advantage of reducing noise.

Please refer to FIG. 4 , which is another embodiment of the present invention. The embodiment of FIG. 4 is substantially the same as the embodiment of FIG. 1 to FIG. 3 , but the embodiment of FIG. 4 and FIG. 1 to FIG. 3 . The embodiment differs in that the direction of rotation of the first fan 1 is in the same direction as the direction of rotation of the second fan 2. Therefore, the present invention can adjust the rotation direction of the first fan 1 to be the same direction or the opposite direction to the rotation direction of the second fan 2 depending on actual use requirements.

In summary, the structure of the supercharged fan of the creation can achieve the intended purpose of use, and solve the lack of conventional knowledge, and has industrial utilization, novelty and progress, fully comply with the requirements of new patent applications, and converts to the patent law.
