[0024] Example 1

[0025] like Figures 1-5 As shown in the figure, a microstructured heat dissipation silicone pad provided in this embodiment of the present invention includes: 100mm thermal pad; An upper thermal pad 200 is disposed on a lower thermal pad 100; and a thermal microstructure, which has a lower auxiliary thermal microstructure and multiple upper auxiliary thermal microstructures. The lower auxiliary thermal microstructure is disposed on the lower thermal pad 100, and the multiple upper auxiliary thermal microstructures are evenly distributed on the upper thermal pad 200. The lower auxiliary thermal microstructure and the multiple upper auxiliary thermal microstructures are interconnected internally and form several heat dissipation channels. The heat dissipated by the electronic components can be discharged through the heat dissipation channels formed in the thermal microstructure.

[0026] In this embodiment, by setting a lower heat dissipation silicone pad 100 and an upper heat dissipation silicone pad 200, and utilizing a heat dissipation microstructure with a lower auxiliary heat dissipation microstructure and multiple sets of upper auxiliary heat dissipation microstructures, the lower auxiliary heat dissipation microstructure and the multiple sets of upper auxiliary heat dissipation microstructures are interconnected to form several heat dissipation channels. The heat emitted by the electronic components can be discharged through these heat dissipation channels, thereby achieving heat dissipation.

[0027] Example 2

[0028] like Figures 1-5 As shown, improvements are made based on Example 1: Furthermore, the lower auxiliary heat dissipation microstructure consists of several heat dissipation holes 110 formed on the lower heat dissipation silicone pad 100.

[0029] In this embodiment, the lower auxiliary heat dissipation microstructure utilizes a plurality of heat dissipation holes 110 formed on the lower heat dissipation silicone pad 100 to provide a channel for heat transfer or temporary storage.

[0030] Furthermore, the multiple sets of upper auxiliary heat dissipation microstructures include multiple heat dissipation cavities 210 formed on the upper heat dissipation silicone pad 200. The multiple heat dissipation cavities 210 are equidistantly distributed along the length direction of the upper heat dissipation silicone pad 200. Each heat dissipation cavity 210 has several heat dissipation holes 220 formed at its top and bottom, and the several heat dissipation holes 220 are interconnected inside and out. Each heat dissipation cavity 210 can be connected to the heat dissipation hole 110 through the heat dissipation hole 220 located on the bottom side.

[0031] In this embodiment, multiple sets of upper auxiliary heat dissipation microstructures are formed by opening multiple heat dissipation cavities 210 that are equidistantly distributed along the length of the upper heat dissipation silicone pad 200. Each heat dissipation cavity 210 has several heat dissipation holes 220 that are open to the inside and outside at the top and bottom. This allows each heat dissipation cavity 210 to be connected to the heat dissipation hole 110 through the heat dissipation hole 220 on the bottom side, so that heat enters the heat dissipation cavity 210 from the heat dissipation hole 110 and is then discharged through the heat dissipation hole 220 at the top.

[0032] Furthermore, the lower surface of the upper heat-dissipating silicone pad 200 is bonded and fixed to the upper surface of the lower heat-dissipating silicone pad 100.

[0033] In this embodiment, by bonding and fixing the lower surface of the upper heat dissipation silicone pad 200 to the upper surface of the lower heat dissipation silicone pad 100, the stability of the overall structure is ensured, and the lower auxiliary heat dissipation microstructure and the upper auxiliary heat dissipation microstructure can be stably connected to form a heat dissipation channel.

[0034] Example 3

[0035] like Figures 1-5 As shown, the difference in Embodiment 2 is: Furthermore, it also includes multiple heat-dissipating silicone strips 300, which are evenly distributed on the upper heat-dissipating silicone pad 200.

[0036] In this embodiment, multiple heat-dissipating silicone strips 300 are evenly distributed on the upper heat-dissipating silicone pad 200, which can increase the contact area with the heat-generating components, assist in absorbing and conducting heat, and improve the overall thermal conductivity.

[0037] Furthermore, a blank space 230 is formed between each adjacent group of heat dissipation holes 220; Each thermal silicone strip 300 is adhesively installed on the corresponding blank part 230.

[0038] In this embodiment, a blank space 230 is formed between adjacent groups of heat dissipation holes 220. Each heat dissipation silicone strip 300 is bonded and installed on the corresponding blank space 230. This not only makes reasonable use of the space of the upper heat dissipation silicone pad 200, but also ensures the stability of the position of the heat dissipation silicone strip 300, so that heat can be stably transferred to the heat dissipation silicone strip 300.

[0039] Furthermore, the upper surface of each thermal silicone strip 300 is coated with a thermal grease coating 310.

[0040] In this embodiment, the upper surface of each heat-dissipating silicone strip 300 is coated with a thermally conductive silicone grease coating 310. The thermally conductive silicone grease coating 310 can reduce the thermal resistance between the heat-dissipating silicone strip 300 and the heat-generating component, so that the heat from the heat-generating component can be transferred to the heat-dissipating silicone strip 300 more efficiently.

[0041] Furthermore, heat dissipation grooves are formed between adjacent heat dissipation silicone strips 300 to facilitate heat dissipation.

[0042] Furthermore, the heat dissipation hole 220 located on the top side is connected to the heat dissipation groove.

[0043] In this embodiment, a heat dissipation groove is formed between adjacent heat dissipation silicone strips 300, and the heat dissipation hole 220 on the top side is connected to the heat dissipation groove, providing an additional channel for heat dissipation. This allows the heat in the heat dissipation cavity 210 to be dissipated more smoothly after entering the heat dissipation groove through the heat dissipation hole 220, thereby improving the overall heat dissipation efficiency.

[0044] Work steps: like Figures 1-5 As shown, electronic components can be mounted on multiple thermal silicone strips 300. After installation, the electronic components are in contact with the thermal grease coating 310 on each thermal silicone strip 300. At this time, the heat emitted by the electronic components is first transferred to the lower thermal silicone pad 100 and then transferred through the heat dissipation holes 110 on the lower thermal silicone pad 100. Next, the heat is discharged through the heat dissipation hole 220 at the bottom of the upper heat dissipation silicone pad 200, which is connected to the heat dissipation hole 110, and enters the heat dissipation cavity 210 that is equidistantly distributed along the length direction on the upper heat dissipation silicone pad 200. Subsequently, the heat diffuses within the heat dissipation cavity 210. On one hand, it is discharged through the heat dissipation hole 220 at the top of the heat dissipation cavity 210. On the other hand, the heat dissipation silicone strip 300 bonded to the blank part 230 of the upper heat dissipation silicone pad 200 efficiently absorbs heat with the help of the thermally conductive silicone grease coating 310 on its surface. Furthermore, the heat dissipation groove between adjacent heat dissipation silicone strips 300 is connected to the top heat dissipation hole 220, further guiding the heat to be discharged from the heat dissipation groove. Meanwhile, the upper heat dissipation silicone pad 200 and the lower heat dissipation silicone pad 100 are bonded and fixed to ensure stable communication between the lower auxiliary heat dissipation microstructure and the upper auxiliary heat dissipation microstructure, forming a complete heat dissipation channel, and ultimately achieving effective heat dissipation of electronic components.

[0045] In summary: 1. Significantly improved heat dissipation efficiency: The heat dissipation holes 110 of the lower heat dissipation silicone pad 100 and the heat dissipation cavity 210 of the upper heat dissipation silicone pad 200 are connected to the heat dissipation holes 220 to form a heat dissipation channel, which efficiently fills the gap between heat-generating and heat-dissipating parts and opens up the heat path. The thermal silicone strip 300 increases the thermal contact area, the thermal grease coating 310 reduces thermal resistance, and the heat dissipation groove provides an additional heat dissipation path. The synergy of these multiple structures greatly enhances heat transfer and heat dissipation efficiency.

[0046] II. Multifunctional and highly adaptable: The lower heat dissipation silicone pad 100, upper heat dissipation silicone pad 200 and heat dissipation silicone strip 300, which are based on silicone, have the functions of insulation, shock absorption and sealing, meet the design requirements of miniaturization and ultra-thinness of equipment, have outstanding processability and practicality, and have a wide range of applicable thicknesses.

[0047] III. Stable and reliable structure: The upper heat dissipation silicone pad 200 and the lower heat dissipation silicone pad 100 are bonded and fixed together, and the heat dissipation silicone strip 300 is bonded and installed to the blank part 230 of the upper heat dissipation silicone pad 200, ensuring the stability of each heat dissipation structure and enabling the heat dissipation channel and auxiliary heat dissipation structure to function stably and continuously.

[0048] It should be noted that the different embodiments described above can be combined, substituted, and used in combination with each other.

[0049] The above are merely preferred embodiments of the present utility model and are not intended to limit the implementation methods and protection scope of the present utility model. Those skilled in the art should realize that any equivalent substitutions and obvious changes made based on the description and illustrations of the present utility model should be included within the protection scope of the present utility model.
