Abstract
Description
Technical Field
[0001] This utility model relates to a woven mesh, and more particularly to a woven mesh structure with a reverse folding zone. Background Technology
[0002] With the rapid advancement of technology, electronic products are continuously evolving towards smaller size and weight, and the heat dissipation components installed within them also need to meet these technological demands. Therefore, two-phase flow cooling devices, such as vapor chambers, have gained attention; however, their circulation efficiency is often affected by the capillary structure within them. For example, while the capillary structure of sintered powder has excellent capillary force, it is not suitable for applications requiring thinner profiles or the ability to withstand repeated bending.
[0003] Therefore, fibrous or woven mesh structures have become a capillary structure design option besides sintered powders. These woven mesh structures are typically formed by interlacing metallic or non-metallic wires in the warp and weft directions, and then cut to appropriate sizes for later use. However, as... Figure 1 As shown, after cutting, the edges of the weft yarns 91 and warp yarns 92 in the braided mesh structure will be exposed, making the yarn prone to peeling, loosening, and falling off, resulting in overflow. Overflow not only damages the capillary effect but also makes the braided mesh structure uneven, unable to be completely flat, thus affecting circulation. Ultimately, the working fluid tends to accumulate at the overflow points, leading to low-temperature freezing and expansion bulging, or dry burning due to the inability of the working fluid to flow back.
[0004] Furthermore, overflowing threads at the edges of the woven mesh can even cause the heat dissipation device to lose its seal, leading to leakage of working fluid. Therefore, how to solve the aforementioned problems and deficiencies in the woven mesh structure is the direction that the designers of this project and related industry players urgently need to study and improve. Utility Model Content
[0005] To effectively solve the above problems, the main objective of this utility model is to provide a woven mesh structure.
[0006] This utility model provides a woven mesh structure, comprising a first mesh component, including a plurality of first threads and a plurality of second threads woven in an interlaced manner; wherein, at least one edge of the first mesh component is folded back to form at least one folded area. This folded area effectively prevents the first mesh component from overflowing.
[0007] In this case, the two ends of the plurality of first lines or the plurality of second lines located in the at least one folded area are formed with a plurality of hook segments.
[0008] In this configuration, the at least one folded area of the first mesh component is formed in pairs at the at least one opposite edge.
[0009] In this case, at least one folded area of the first mesh component is folded back towards the same side of the first mesh component.
[0010] The at least one folded area of the first mesh component is formed around the at least one edge of the first mesh component.
[0011] The first mesh component is rectangular.
[0012] This utility model provides a woven mesh structure, comprising a first mesh member and at least one second mesh member. The first mesh member includes a plurality of first threads and a plurality of second threads woven in an interlaced manner, and at least one folded area is formed by folding at least one edge of the first mesh member; and the at least one second mesh member is placed on one side of the first mesh member, and at least one edge of the second mesh member is covered by the at least one folded area of the first mesh member.
[0013] In this configuration, at least one folded area of the first mesh component is folded back toward the same side of the first mesh component and correspondingly covers at least one edge of the second mesh component.
[0014] This invention improves the structural stability and anti-spinning ability of the first mesh component by providing at least one folding area at the edge of the woven mesh structure. This folding area compresses or confines the wires at the edge to the inside of the first mesh component, significantly enhancing its structural stability and anti-spinning ability. Simultaneously, the folding area further covers and protects the plurality of second mesh components.
[0015] This invention increases friction and restricts displacement through the folded area, which effectively limits the freedom of movement of the wire ends at the edge, thereby reducing slippage and loosening of the wire caused by mechanical force, friction or vibration. This significantly reduces the problem of overflowing wires (wire ends coming off, lateral detachment) and improves the overall durability and capillary effect stability of the woven mesh.

[0022] The above-mentioned objectives of this utility model, as well as its structural and functional characteristics, will be explained with reference to the preferred embodiments shown in the accompanying drawings. Please refer to... Figure 2 The diagram shown is a cross-sectional schematic of an embodiment of the woven mesh structure of this utility model. Figure 3 This is a partial schematic diagram of the edge of an embodiment of the woven mesh structure of this utility model; Figure 4 This is a cross-sectional schematic diagram of another embodiment of the woven mesh structure of this utility model; and, Figure 5 This is a partial schematic diagram of the edge of another embodiment of the woven mesh structure of this utility model.
[0023] like Figure 2 and Figure 3 As shown, this utility model provides a mesh structure 1, which includes at least one first mesh component 11. For example, the first mesh component 11 is woven from a plurality of first threads 111 and a plurality of second threads 112, which are interlaced in mutually perpendicular directions. The plurality of first threads 111 may be weft threads, and the plurality of second threads 112 may be warp threads, or vice versa.
[0024] In some embodiments, the first mesh member 11 can be directly cut from a large-area woven mesh. Thereby, the first mesh member 11 has multiple edges formed by cutting (e.g., main edges 11E). See also... Figure 2 and Figure 3 As shown, the first mesh component 11 of this invention has at least one folded area 110, which is formed by at least one fold at the edge (main edge 11E) of the first mesh component 11. For example, the folded area 110 can be formed by folding the plurality of first lines 111 back along the weft direction (the plurality of first lines 111), so that after the plurality of first lines 111 of the folded area 110 are folded back along the normal direction at the edge, they are in close contact with the surface of one side of the first mesh component 11.
[0025] Please see Figure 3As shown, in this embodiment of the present invention, by forming the folding area 110, the wire located at the main edge 11E is compressed through the folding, thereby increasing friction and limiting displacement. For example, when the plurality of first wires 111 in the folding area 110 are pressed back, a plurality of hook segments 110A will be formed at both ends of the plurality of first wires 111 in the folding area 110. Because of the folding, the plurality of hook segments 110A will clamp the plurality of second wires 112 that are intertwined therein. At this time, the friction between the wires in the folding area 110 will be greatly increased, thereby effectively preventing the situation where the wire at the edge is prone to overflow due to insufficient binding force, as is common in the present invention.
[0026] In some embodiments, please refer to [link / reference]. Figure 2 , Figure 3 As shown, the at least one folding area 110 of the first mesh member 11 can be formed in pairs at opposite edges of the first mesh member 11. At this time, the ends of the plurality of first threads 111 or the plurality of second threads 112 located in the at least one folding area 110 will be folded back to form pairs of opposing hook segments 110A. These hook segments 110A, together with the transversely interwoven threads, constitute the at least one folding area 110, increasing friction and effectively limiting the movement of the threads. For example, when the hook segments 110A at both ends of the plurality of first threads 111 are folded back in pairs and hooked back to the interlaced plurality of second threads 112, the ends of the plurality of first threads 111 will be restricted by the plurality of second threads 112, thus preventing them from easily coming off due to external force and effectively preventing the ends of the plurality of first threads 111 from coming off. Meanwhile, the plurality of second threads 112 will also be less likely to slip off laterally because they are blocked on both sides by the plurality of hook segments 110A of the plurality of first threads 111. In this way, the slippage and loosening of the threads are effectively restricted, and the overall structural stability and anti-spillage ability of the first mesh component 11, especially at the edges (e.g., the main edge 11E), are significantly improved.
[0027] In some embodiments, such as Figure 2As shown, the at least one folded area 110 of the first mesh member 11 can also be folded towards the same side of the first mesh member 11. Simultaneously, the at least one folded area 110 of the first mesh member 11 can be formed around the edge of the first mesh member 11 (i.e., the main edge 11E). This ensures that the edge is fully reinforced by the at least one folded area 110 and its paired arrangement, achieving a stable and complete anti-overflow effect around the edge (main edge 11E). For example, the first mesh member 11 can be rectangular, wherein the ends of the plurality of first lines 111 and the plurality of second lines 112 are respectively formed with a plurality of hook segments 110A, which together constitute the at least one folded area 110. In this case, the at least one folded area 110 is formed in pairs on two pairs of opposite sides of the rectangular first mesh member 11.
[0028] In other embodiments, such as Figure 4 and Figure 5 As shown, in addition to the first mesh component 11, it may also include at least one second mesh component 12, for example, one, two, three, or more of the plurality of second mesh components 12. The second mesh component 12 can also be woven from yarn in a cross-woven manner in both warp and weft directions, and this invention is not limited thereto. The plurality of second mesh components 12 are placed on one side of the first mesh component 11, and the edge of the second mesh component 12 (i.e., the secondary edge 12E) is covered by the at least one folded area 110 of the first mesh component 11. In this way, the at least one folded area 110 not only provides structural stability and anti-overflow for the first mesh component 11, but also protects the edge of the plurality of second mesh components 12 (i.e., the secondary edge 12E), preventing the yarn at the secondary edge 12E of the second mesh component 12 from slipping or loosening. Therefore, in the design of using multi-layer woven mesh in the structure, the at least one reverse folding area 110 of this utility model can effectively prevent overflow of filaments for all the woven mesh components at once.
[0029] Similarly, the at least one folded area 110 of the first mesh member 11 can also be folded back towards the same side of the first mesh member 11, correspondingly covering all edges (secondary edges 12E) of the second mesh member 12. Furthermore, the at least one folded area 110 of the first mesh member 11 can be formed around the edge (main edge 11E) of the first mesh member 11, thereby completely covering all edges (secondary edges 12E) of the second mesh member 12.
[0030] In summary, by increasing friction and restricting displacement through the folded area 110, a structure can be formed in the first mesh component 11 that effectively restricts the freedom of movement of the wire ends, thereby reducing wire peeling, loosening, and detachment at the edges. This significantly reduces problems such as filament overflow (wire end detachment, lateral detachment), improving the overall durability and capillary effect stability of the braided mesh. Thus, the long-standing problem of filament overflow at the edges of the braided mesh structure can be solved simply and effectively, optimizing its reliability and lifespan in various applications such as heat dissipation, filtration, and capillary structures.
