To maintain the following description of the embodiments of the present disclosure clear and concise, a detailed description of known functions and known components have been omitted from the present disclosure.
The first embodiment of the present disclosure provides a vortex generator, where the vortex generator may be disposed on a blade of a fan to improve aerodynamic performance of a large-thickness airfoil of the fan blade, and improve power generation efficiency, and the vortex generator includes a bottom plate portion 1, where the bottom plate portion 1 includes a first bottom plate 11 and a second bottom plate 12, and the first bottom plate 11 and the second bottom plate 12 are connected by a connecting portion 13, so that the first bottom plate 11 and the second bottom plate 12 are respectively located on two sides of the connecting portion 13 and are symmetrically disposed with respect to the connecting portion 13, where the connecting portion 13 is, for example, a special-shaped connecting portion. The first base plate 11 and the second base plate 12 are connected by the connecting portion 13 to improve the easy installation of the vortex generator. The connecting part 13 is designed to be a special-shaped curved surface structure to realize weight reduction and connecting functions.
The first air receiving plate 10 and the second air receiving plate 20 are respectively disposed on first surfaces of the first bottom plate 11 and the second bottom plate 12 of the bottom plate 1, and are respectively disposed perpendicular to the bottom plate 1. The first wind receiving plate 10 and the second wind receiving plate 20 are symmetrically arranged like the first bottom plate 11 and the second bottom plate 12, so that a predetermined angle is formed between the first wind receiving plate 10 and the second wind receiving plate 20. Wherein a first distance H between the first ends of the first wind receiving plate 10 and the second wind receiving plate 20 is smaller than a second distance H between the second ends of the first wind receiving plate 10 and the second wind receiving plate 20.
Further, a plurality of protrusions 14 are provided on a second surface of the bottom plate portion 1 opposite to the first surface, the plurality of protrusions 14 are uniformly provided on the second surface of the bottom plate portion 1 according to a predetermined manner, the protrusions 14 may be, for example, cylindrical, square, diamond or other irregular structures, and in one embodiment, the height of the protrusions 14 may be, for example, 0.05-1mm, wherein the second surface is a surface for connecting with a blade of a fan, and the protrusions 14 are provided to increase surface roughness so as to improve bonding strength with the blade.
Further, the first wind receiving plate 10 and the second wind receiving plate 20 are of a gradual change structure, specifically, when viewed from a direction parallel to the bottom plate portion 1, a width from the bottom B to the top a of the first wind receiving plate 10 or the second wind receiving plate 20 is gradually narrowed, and when viewed from a direction perpendicular to the bottom plate portion 1, a thickness from the bottom B to the top a of the first wind receiving plate 10 or the second wind receiving plate 20 is also gradually narrowed, so that the stability and strength of each wind receiving plate are increased by the wider arrangement of the bottom B of the first wind receiving plate 10 or the second wind receiving plate 20. Further, the height of the second end of the first wind receiving plate 10 or the second wind receiving plate 20 is the largest as viewed in the direction perpendicular to the floor portion 1, which can improve aerodynamic performance to the maximum extent.
Further, the bottom plate edges of the first bottom plate 11 and the second bottom plate 12 are of a gradual structure, and the gradual width can be 0.5-3mm, for example, wherein the gradual width is determined according to the overall size of the vortex generator. The edges of the first bottom plate 11 and the second bottom plate 12 are the thinnest, and the thinnest position can reach 0.1-0.5 mm. This can reduce the negative impact on the wind field.
In order to better improve the use effect of the vortex generator, the windward position of the vortex generator is generally set to be as smooth as possible without obvious bulges so as to reduce the influence of the edge of the vortex generator on the wind condition.
The vortex generator related to the embodiment of the disclosure has a corresponding manufacturing method, wherein the traditional manufacturing method of the vortex generator is injection molding, the difficulty of the traditional injection molding process is higher when a thin-wall product with the thickness of less than 0.5mm is manufactured, and even if the thin-wall product can be injection molded, the thin-wall product is easy to warp and deform. In addition, for small-size high-precision products, the precision of the injection mold is required to be high, so that the processing cost is increased, and the small-size high-precision position of the mold is damaged. In addition, when an injection molding process is adopted, the vortex generator is required to be rough in the glued joint bottom surface, and a rough structure is designed on the surface of a corresponding mold, so that the difficulty in demolding after injection molding is increased. The demoulding difficulty of the thin-wall structure is increased, and the rejection rate is higher.
Based on the vortex generator according to the first embodiment of the present disclosure, a second embodiment of the present disclosure provides a manufacturing method for manufacturing the vortex generator by using a 3D printing technique: the method comprises the following steps:
s1, constructing three-dimensional modeling of the vortex generator;
s2, obtaining the first bottom plate 11, the second bottom plate 12, the connecting part 13, the first air receiving plate 10 and the second air receiving plate 20 in a 3D printing mode and carrying out edge gradual change polishing treatment; the model is manufactured by 3D printing, the printing technology includes, but is not limited to, melt extrusion, laser sintering and the like, and the material includes, but is not limited to, PC (polycarbonate), modified PC (polycarbonate), ASA (copolymerized by styrene acrylonitrile and acryl rubber), modified ASA, ABS (terpolymer of three monomers of acrylonitrile (a), butadiene (B) and styrene (S)), PA (polyamide) and the composite material thereof.
S3, the first bottom plate 11 and the second bottom plate 12 are connected by the connecting portion 13, and the first wind receiving plate 10 and the second wind receiving plate 20 are respectively mounted on the first bottom plate 11 and the second bottom plate 12.
According to the manufacturing method of the vortex generator, the three-dimensional digital analogy of the vortex generator can be optimally designed in the early design stage of manufacturing, and a small-size, high-precision and special-shaped complex structural part is manufactured based on three-dimensional modeling, wherein the vortex generator after the optimal design can not be formed by adopting the traditional injection molding process, a mold is not needed in the process of manufacturing the vortex generator by the 3D printing technology, and the digital analogy can be directly formed for manufacturing after the design optimization. The vortex generator manufactured by adopting the 3D printing technology has good flowing performance and can solve the problems that the thin wall size cannot be realized and the warping deformation is caused. Overall, the production of the vortex generators by means of a 3D printing method can offer advantages not generally available with conventional injection molding processes, such as: forming a thin-wall structure; a mould is not needed for forming a complex structure; cost advantage; the design optimization space increases.
