[0003] In related technologies, conventional heat dissipation structures are rigid, cannot be stretched, and are prone to breakage when bent. For foldable terminals, which have two usage states—folded and unfolded—conventional heat dissipation structures cannot stretch or contract, making it impossible to accommodate the distance difference between these two states. Therefore, conventional heat dissipation structures are unsuitable for heat dissipation in foldable terminals. Summary of the Invention
[0004] The following is an overview of the subject matter described in detail herein. This overview is not intended to limit the scope of the claims.
[0005] This invention provides a heat dissipation structure, a heat dissipation component, a method for installing the heat dissipation component, and a foldable terminal. The heat dissipation structure itself can be stretched and contracted.
[0006] In a first aspect, embodiments of the present invention provide a heat dissipation structure, comprising:
[0007] Multiple flexible heat-conducting units;
[0008] At least one layer of heat-conducting mesh, the heat-conducting mesh comprising multiple intersecting mesh wires, each pair of intersecting mesh wires being rotatable relative to each other, the multiple mesh wires intersecting to form gaps, and the elastic heat-conducting unit disposed within the gaps.
[0009] Secondly, embodiments of the present invention provide a heat dissipation component, including the heat dissipation structure described in the first aspect above.
[0010] Thirdly, embodiments of the present invention provide a foldable terminal, including a housing and a heat dissipation component as described in the second aspect above. The housing has a first heat dissipation surface and a second heat dissipation surface that are rotatable relative to each other, and a gap is provided between the first heat dissipation surface and the second heat dissipation surface. The heat dissipation component includes:
[0011] A first heat dissipation part is disposed on the first heat dissipation surface;
[0012] The second heat dissipation part is disposed on the second heat dissipation surface;
[0013] A connecting part is connected to the first heat dissipation part and the second heat dissipation part respectively, and the connecting part passes through the gap;
[0014] The first heat dissipation part, the second heat dissipation part, and the connecting part are all composed of the heat dissipation structure.
[0015] Fourthly, embodiments of the present invention provide a method for installing a heat dissipation component, applied to a foldable terminal. The foldable terminal includes a housing and the heat dissipation component as described in the second aspect above. The housing has a first heat dissipation surface and a second heat dissipation surface that are rotatable relative to each other. A gap is provided between the first heat dissipation surface and the second heat dissipation surface. The heat dissipation component includes a first heat dissipation part, a second heat dissipation part, and a connecting part that is respectively connected to the first heat dissipation part and the second heat dissipation part. The method includes:
[0016] Fix the first heat dissipation part to the first heat dissipation surface;
[0017] Pull the corner of the second heat dissipation part until the second heat dissipation part can pass through the gap;

[0021] The embodiments of the present invention include: a heat dissipation structure comprising multiple elastic heat-conducting units and at least one layer of heat-conducting mesh. The heat-conducting mesh comprises multiple intersecting mesh lines, which can rotate relative to each other. The multiple mesh lines intersect to form gaps, and the elastic heat-conducting units are disposed within the gaps. Therefore, when the heat-conducting mesh is stretched by an external force, its length along the stretching direction will increase due to the extension, while its length perpendicular to the stretching direction will decrease due to the contraction. At the same time, the elastic heat-conducting units also deform under the drive of the mesh lines and deform in unison with the heat-conducting mesh, thereby enabling the entire heat dissipation structure to achieve stretching and contraction.

[0032] To make the objectives, technical solutions, and advantages of this invention clearer, the invention will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative and not intended to limit the invention.
[0033] It should be understood that in the description of the embodiments of the present invention, "multiple" (or "amounts") means two or more, "greater than," "less than," and "exceeding" are understood to exclude the stated number, while "above," "below," and "within" are understood to include the stated number. If "first," "second," etc., are used in the description, they are only for the purpose of distinguishing technical features and should not be construed as indicating or implying relative importance, or implicitly indicating the number of indicated technical features, or implicitly indicating the order of the indicated technical features.
[0034] With the development of science and technology, flexible screen devices are developing towards larger screens. Based on the foldability of flexible screens, it is possible for flexible screen devices to be foldable, thus forming foldable terminals, which provides great convenience for flexible screen devices that carry large screens.
[0035] In related technologies, conventional heat dissipation structures are rigid, cannot be stretched, and are prone to breakage when bent. For foldable terminals, which have two usage states—folded and unfolded—conventional heat dissipation structures cannot stretch or contract, making it impossible to accommodate the distance difference between these two states. Therefore, conventional heat dissipation structures are unsuitable for heat dissipation in foldable terminals.
[0036] This invention provides a heat dissipation structure, a heat dissipation component, an installation method thereof, and a foldable terminal. The heat dissipation structure includes multiple elastic heat-conducting units and at least one layer of heat-conducting mesh. The heat-conducting mesh includes multiple intersecting mesh lines, which can rotate relative to each other. The multiple mesh lines intersect to form gaps, and the elastic heat-conducting units are disposed within the gaps. Therefore, when the heat-conducting mesh is stretched by an external force, its length along the stretching direction will increase due to extension, while its length perpendicular to the stretching direction will decrease due to contraction. At the same time, the elastic heat-conducting units also deform under the drive of the mesh lines and deform in the same way as the heat-conducting mesh. This allows the entire heat dissipation structure to achieve stretching and contraction, which can meet the distance difference between the folded and unfolded usage states of the foldable terminal. Even in the case of bending or stretching, it will not break. Moreover, placing the elastic heat-conducting units with elastic deformation within the gaps of the heat-conducting mesh can improve the heat conduction performance, thereby meeting the heat dissipation needs of the foldable terminal. Furthermore, for heat dissipation structures with multi-layer heat-conducting meshes, the heat flux of the heat dissipation structure can be further improved, provided that the requirements for different thicknesses of heat dissipation materials are met and the structural design space allows, thus enabling the foldable terminal to achieve better overall heat dissipation performance. Therefore, the heat dissipation structure provided in this embodiment can be stretched and contracted, and will not break when bent, making it suitable for the heat dissipation needs of foldable terminals.
[0037] like Figures 1 to 3 As shown, one embodiment of the present invention provides a heat dissipation structure 100. The heat dissipation structure 100 includes a plurality of elastic heat-conducting units 110 and at least one layer of heat-conducting mesh 120, wherein the heat-conducting mesh 120 includes a plurality of intersecting mesh wires 121, each pair of intersecting mesh wires 121 being rotatable relative to each other, the plurality of mesh wires 121 intersecting to form gaps 122, and the elastic heat-conducting units 110 are disposed within the gaps 122.
[0038] In this embodiment, when the heat-conducting mesh 120 is stretched by an external force, the length of the heat-conducting mesh 120 along the stretching direction will increase due to the stretching, while its length perpendicular to the stretching direction will decrease due to the contraction. For example... Figure 1 and Figure 2The microstructure shown, taking the stretching of the heat-conducting mesh 120 along the X-axis as an example, involves relative rotation between the intersecting mesh lines 121, and the gaps 122 formed by the intersecting mesh lines 121 change from a square arrangement to a rhomboid arrangement. In the X-axis direction, the length of the heat-conducting mesh 120 increases due to stretching; in the Y-axis direction, the length of the heat-conducting mesh 120 decreases due to contraction. Meanwhile, since the elastic heat-conducting unit 110 fills the gap 122, it also deforms along with the gap 122 under the drive of the mesh 121. That is, the elastic heat-conducting unit 110 deforms in unison with the heat-conducting mesh 120. When the heat-conducting mesh 120 is released by an external force in the X-axis direction, the elastic heat-conducting unit 110 recovers its elastic deformation, driving the heat-conducting mesh 120 back to its original state. This allows the entire heat dissipation structure 100 to stretch and contract, meeting the distance difference between the folded and unfolded states of the foldable terminal. Even in the event of bending or stretching, it will not break. Moreover, placing the elastically deformable heat-conducting unit 110 within the gap 122 of the heat-conducting mesh 120 improves heat conduction performance, thereby meeting the heat dissipation needs of the foldable terminal. In addition, when the heat-conducting mesh 120 is stretched, the gap 122 is compressed, thus squeezing the air within the gap 122, further enhancing the heat dissipation performance of the heat dissipation structure 100.
[0039] It should be noted that the heat-conducting mesh 120 can be a single layer or multiple layers. For example... Figure 3 The microstructure shown can further improve the heat flux of the heat dissipation structure 100 with multi-layer heat conduction mesh 120, while meeting the requirements for different heat dissipation material thicknesses and within the allowable space of the structural design, so that the foldable terminal can obtain better overall heat dissipation performance.
[0040] In one embodiment, a plurality of elastic heat-conducting units 110 are uniformly arranged within the heat-conducting mesh 120.
[0041] In this embodiment, multiple elastic heat-conducting units 110 are evenly arranged within the heat-conducting mesh 120. Specifically, the gaps 122 formed by the interlacing mesh lines 121 within the heat-conducting mesh 120 are approximately equal, and the size of each elastic heat-conducting unit 110 is also approximately equal. This ensures that the multiple elastic heat-conducting units 110 are evenly arranged within the heat-conducting mesh 120, resulting in a more uniform heat dissipation effect and further improving the stretchability and shrinkability of the heat-conducting mesh 120. Based on this, the entire heat dissipation structure 100 can be stretched and contracted, satisfying the distance difference between the folded and unfolded states of the foldable terminal, and will not break even in the event of bending or stretching.
[0042] In one embodiment, the flexible thermally conductive unit 110 is a mixture comprising alumina and silicon micropowder.
[0043] The elastic thermally conductive unit 110 can be made of a material with strong elasticity and thermal conductivity, such as alumina, magnesium oxide, zinc oxide, aluminum nitride, boron nitride, and silicon carbide. In this embodiment, a mixture including, but not limited to, alumina and silicon micropowder has particularly good elastic thermal conductivity, wherein the alumina particles are on the micrometer scale. It should be noted that using a mixture with alumina and silicon micropowder as the main components is only a preferred embodiment. Nanoparticle powder or graphene oxide powder can also be added to the alumina and silicon micropowder for further processing to improve thermal conductivity. By filling the gaps 122 of the thermally conductive mesh 120 with the elastic thermally conductive unit 110, the heat dissipation performance of the thermally conductive mesh 120 is ensured not to be weakened by the presence of a large number of gaps 122. Therefore, filling the gaps 122 of the thermally conductive mesh 120 with the elastically deformable thermally conductive unit 110 can improve thermal conductivity, thereby meeting the heat dissipation requirements of the foldable terminal.
[0044] In one embodiment, the network cable 121 is a carbon nanotube.
[0045] The mesh 121 can be made of a micro-thermal conductive material with ultra-high thermal conductivity, including but not limited to carbon nanotubes. In this embodiment, the use of carbon nanotubes for the mesh 121 is only a preferred embodiment. Specifically, the carbon nanotubes are woven into a micro-mesh structure to form the heat-conducting mesh 120. Multiple mesh wires 121 of the heat-conducting mesh 120 interweave to form gaps 122, which change from a square arrangement to a diamond arrangement as the heat-conducting mesh 120 is stretched. Elastic thermally conductive units 110 are filled in the gaps 122. When the heat-conducting mesh 120 is stretched, the elastic thermally conductive units 110 also deform along with the gaps 122 under the drive of the mesh wires 121, so that the elastic thermally conductive units 110 deform in unison with the heat-conducting mesh 120, thereby enabling the entire heat dissipation structure 100 to stretch and contract.
[0046] In one embodiment, when the number of heat-conducting meshes 120 is multi-layered, the multi-layered heat-conducting meshes 120 include at least one first heat-conducting mesh 130 and at least one second heat-conducting mesh 140, and the first heat-conducting mesh 130 and the second heat-conducting mesh 140 are arranged perpendicular to each other.
[0047] In this embodiment, as Figure 3As shown, when the number of heat-conducting meshes 120 is multi-layered, the multi-layered heat-conducting meshes 120 are formed into a 3D three-dimensional structure through processing technology. This three-dimensional structure includes at least one first heat-conducting mesh 130 and at least one second heat-conducting mesh 140. The first heat-conducting meshes 130 and the second heat-conducting meshes 140 are arranged perpendicular to each other, so that the first heat-conducting meshes 130 and the second heat-conducting meshes 140 are interlaced, and the gaps 122 formed by the interlacing are filled with elastic heat-conducting units 110. For the heat dissipation structure 100 with multi-layered heat-conducting meshes 120, under the premise of meeting the heat dissipation thickness requirements and within the allowable space of the structural design, it can further improve the heat flux of the heat dissipation structure 100, so that the foldable terminal can obtain better overall heat dissipation performance.
[0048] In one embodiment, the first heat-conducting mesh 130 and the second heat-conducting mesh 140 are integrally formed.
[0049] In this embodiment, as Figure 3 As shown, the first heat-conducting mesh 130 and the second heat-conducting mesh 140 are not only interlocked but also integrally formed. That is, the multi-layer heat-conducting mesh 120 is not spliced together by layer-by-layer combination, but is made by integral forming.
[0050] like Figure 4 As shown, this embodiment of the invention also provides a heat dissipation component 200, which includes a heat dissipation structure 100.
[0051] In one embodiment, since the heat dissipation component 200 adopts the heat dissipation structure 100, the macroscopic heat dissipation component 200 also possesses the telescopic and heat dissipation performance of the heat dissipation structure 100. Based on this, the heat dissipation component 200 can be stretched and contracted, and in the application scenario of foldable terminals, it can meet the distance difference between the folded and unfolded usage states of the foldable terminal, and will not break even in the event of bending or stretching.
[0052] It should be noted that the heat dissipation component 200 achieves good scalability based on the heat dissipation structure 100, and can be used in scenarios that require a certain degree of stretching. It does not need to be folded at the macro level. Therefore, the heat dissipation component 200 is not subject to the structural constraints of the foldable terminal and has strong versatility.
[0053] like Figure 5As shown, this embodiment of the invention also provides a foldable terminal, including a housing 300 and a heat dissipation component 200. The housing 300 has a first heat dissipation surface 310 and a second heat dissipation surface 320 that can rotate relative to each other. A gap 330 is provided between the first heat dissipation surface 310 and the second heat dissipation surface 320. The heat dissipation component 200 includes a first heat dissipation part 210, a second heat dissipation part 220 and a connecting part 230. The first heat dissipation part 210 is disposed on the first heat dissipation surface 310, the second heat dissipation part 220 is disposed on the second heat dissipation surface 320, and the connecting part 230 is connected to the first heat dissipation part 210 and the second heat dissipation part 220 respectively, and the connecting part 230 passes through the gap 330. The first heat dissipation part 210, the second heat dissipation part 220 and the connecting part 230 are all composed of a heat dissipation structure 100.
[0054] It should be noted that foldable terminals include, but are not limited to, foldable phones.
[0055] In one embodiment, taking a foldable phone as an example, the internal components and other heat sources of a typical foldable phone are located on the left side, while only the battery is on the right. In some user scenarios, this can cause the temperature difference between the left and right sides of the foldable phone to exceed 10°C, resulting in a poor user experience. Figure 6 and Figure 7 As shown, since the first heat dissipation part 210, the second heat dissipation part 220, and the connecting part 230 are all composed of heat dissipation structure 100, the heat dissipation component 200 has the characteristics of being stretchable and retractable. Therefore, the heat dissipation component 200 can easily pass through the gap 330 between the first heat dissipation surface 310 and the second heat dissipation surface 320 of the foldable phone. Specifically, the first heat dissipation part 210 is disposed on the first heat dissipation surface 310, the second heat dissipation part 220 is disposed on the second heat dissipation surface 320, and the connecting part 230 passes through the gap 330. In addition, since the connecting part 230 is connected to the first heat dissipation part 210 and the second heat dissipation part 220 respectively, it is equivalent to building a heat dissipation path between the first heat dissipation part 210 and the second heat dissipation part 220, which achieves the effect of temperature uniformity, effectively reducing the temperature difference between the first heat dissipation part 210 and the second heat dissipation part 220, thereby improving the user experience.
[0056] Meanwhile, since the first heat dissipation part 210, the second heat dissipation part 220 and the connecting part 230 are all composed of heat dissipation structure 100, the heat dissipation component 200 also has good heat dissipation performance, thereby meeting the heat dissipation needs of the foldable terminal.
[0057] When the foldable terminal is folded, the heat dissipation component 200 passing through the gap 330 will be subjected to an external force in the X direction. Since the heat dissipation component 200 has the characteristics of the heat dissipation structure 100, it has the ability to extend in the X direction and can therefore be stretched. When the foldable terminal is unfolded, the external force on the heat dissipation component 200 in the X direction is released, and the heat dissipation component 200 returns to its original state. Therefore, the heat dissipation component 200 can meet the distance difference requirements between the folded and unfolded usage states of the foldable terminal.
[0058] Based on this, the heat dissipation component 200 provided in this embodiment can stretch and contract itself, which can meet the distance difference between the two usage states of the foldable terminal when it is folded and unfolded, and will not break even when it is bent or stretched, thus adapting to the heat dissipation requirements of the foldable terminal.
[0059] like Figure 8 As shown, this embodiment of the invention also provides a method for installing a heat dissipation component. This method is applied to a foldable terminal. The foldable terminal includes a housing and a heat dissipation component. The housing has a first heat dissipation surface and a second heat dissipation surface that can rotate relative to each other. A gap is provided between the first and second heat dissipation surfaces. The heat dissipation component includes a first heat dissipation part, a second heat dissipation part, and connecting parts respectively connected to the first and second heat dissipation parts. The method includes, but is not limited to, the following steps:
[0060] Step 101: Fix the first heat dissipation part to the first heat dissipation surface;
[0061] Step 102: Pull the corner of the second heat dissipation part until the second heat dissipation part can pass through the gap;
[0062] Step 103: Move the heat dissipation component toward the gap so that the connecting part passes through the gap;
[0063] Step 104: Loosen the corners of the second heat sink and fix the second heat sink to the second heat sink surface.
[0064] In one embodiment, the first heat sink is first fixed to the first heat sink surface. Then, the corners of the second heat sink are pulled until the second heat sink can pass through the gap. The heat sink component is then moved toward the gap so that the connecting part passes through the gap. Finally, the corners of the second heat sink are loosened and the second heat sink is fixed to the second heat sink surface. The entire installation process is simple, convenient, and easy to operate. The fixing method includes, but is not limited to, electrostatic adsorption.
[0065] Specifically, such as Figure 7As shown, when the corners of the heat dissipation component are pulled, the heat dissipation component is stretched along the X-axis direction, and the heat dissipation component can reduce its size in the Y-axis direction, thereby passing through the restricted gap to build a heat dissipation path between the first heat dissipation surface and the second heat dissipation surface on the left and right sides of the foldable terminal, so as to play a role in equalizing the temperature, effectively reducing the temperature difference between the first heat dissipation part and the second heat dissipation part, thereby improving the user experience.
[0066] It should be noted that the heat dissipation component achieves good scalability based on its heat dissipation structure, enabling its application in scenarios requiring a certain degree of stretching. It does not require any further macroscopic folding, therefore, the heat dissipation component is not constrained by the structure of the foldable terminal and possesses strong versatility. Thus, the heat dissipation component can be stretched and contracted, accommodating the distance difference between the folded and unfolded states of the foldable terminal. Furthermore, the heat dissipation component will not break even under bending or stretching conditions.
[0067] In addition, embodiments of the present invention also provide a foldable terminal, which includes a heat dissipation structure or heat dissipation component.
[0068] Since the foldable terminal includes at least this heat dissipation structure, which comprises multiple elastic heat-conducting units and at least one layer of heat-conducting mesh, and the heat-conducting mesh comprises multiple intersecting mesh lines, each pair of intersecting mesh lines being rotatable relative to each other, and the multiple mesh lines intersecting to form gaps, with the elastic heat-conducting units disposed within these gaps, when the heat-conducting mesh is subjected to external force stretching, its length along the stretching direction will increase due to extension, while its length perpendicular to the stretching direction will decrease due to contraction. Simultaneously, the elastic heat-conducting units also deform under the drive of the mesh lines, and will... As the heat-conducting mesh undergoes uniform deformation, when the mesh is released from an external force along the X-axis, the elastic heat-conducting unit recovers its elastic deformation, driving the mesh back to its original state. This allows the entire heat dissipation structure to stretch and contract, accommodating the distance difference between the folded and unfolded states of the foldable terminal. It will not break even under bending or stretching conditions. Furthermore, placing elastically deformable heat-conducting units within the gaps of the heat-conducting mesh enhances thermal conductivity, thus meeting the heat dissipation needs of the foldable terminal. Additionally, when the heat-conducting mesh is stretched, the gaps are compressed, compressing the air within them and further improving the heat dissipation performance. For heat dissipation structures with multi-layered heat-conducting meshes, within the constraints of varying material thicknesses and structural design space, the heat flux can be further increased, resulting in better overall heat dissipation performance for the foldable terminal. Therefore, the heat dissipation structure itself can stretch and contract, and it will not break when bent, making it suitable for the heat dissipation requirements of foldable terminals.
[0069] Similarly, when a foldable terminal includes a heat dissipation component, because the heat dissipation component adopts a heat dissipation structure, it also possesses the expansion and contraction performance of the heat dissipation structure on a macroscopic level. Based on this, the heat dissipation component can be stretched and contracted, and in the application scenario of a foldable terminal, it can meet the distance difference between the folded and unfolded usage states of the foldable terminal. Even in the case of bending or stretching, it will not break, thus adapting to the heat dissipation requirements of foldable terminals.
[0070] The above provides a detailed description of the preferred embodiments of the present invention. However, the present invention is not limited to the above embodiments. Those skilled in the art can make various equivalent modifications or substitutions without departing from the spirit of the present invention. All such equivalent modifications or substitutions are included within the scope defined by the claims of the present invention.
