Description

Technical Field

[0001] The utility model relates to the technical field of mica sheets, in particular to a mica sheet with good heat dissipation effect. Background Art

[0002] Mica sheets, as a common insulating and thermal insulation material, are widely used in electronics, electrical appliances, aerospace, and other fields due to their excellent electrical properties, high-temperature resistance, and mechanical strength. However, with the increasing integration of modern electronic devices, especially in 5G communications and high-performance computing, the requirements for heat dissipation materials are becoming increasingly stringent.

[0003] Traditional mica sheets will generate a lot of heat after long-term use. The mica sheets themselves have limited heat dissipation effect and cannot effectively dissipate the heat generated by high-power devices, causing the device temperature to rise, affecting performance and lifespan.

[0004] Therefore, in view of the above situation, it is urgent to develop a mica sheet with good heat dissipation effect to overcome the shortcomings in current practical applications. Utility Model Content

[0005] The purpose of the embodiments of the present invention is to provide a mica sheet with good heat dissipation effect, aiming to solve the problems raised in the above-mentioned background technology.

[0006] To achieve the above objectives, the present invention provides the following technical solutions:

[0007] A mica sheet with good heat dissipation effect comprises an outer shell, an upper mica sheet and a lower mica sheet, the upper end of the inner wall of the outer shell is fixedly connected to the upper mica sheet, the lower end of the inner wall of the outer shell is fixedly connected to the lower mica sheet, and the end surfaces of the upper mica sheet and the lower mica sheet close to each other are coated with a thermal conductive layer, the thermal conductive layers are fixed with heat dissipation plates, the heat dissipation plates are provided with a plurality of evenly distributed heat dissipation grooves, each heat dissipation groove is fixed with a plurality of spoilers, second air inlet grooves are provided on both side walls of the outer shell, each of the heat dissipation plates close to the thermal conductive layer is provided with a first air hole and a second air hole, and the two side walls of the outer shell are also provided with a plurality of evenly distributed first air inlet grooves, and the first air inlet grooves are connected to the corresponding first air hole and second air hole.

[0008] According to a further technical solution, the heat conducting layer is made of a high thermal conductivity polymer.

[0009] According to a further technical solution, the spoilers in each heat dissipation slot are arranged obliquely, and the spoilers in the same heat dissipation slot are not coplanar and intersect with each other.

[0010] According to a further technical solution, a plurality of evenly distributed windless power caps are fixedly provided on the other two side walls of the shell.

[0011] According to a further technical solution, the first air hole and the second air hole are arranged alternately, the first air hole and the second air hole are of the same size, and the radius of the first air hole gradually increases from one side of the heat dissipation plate to the other side, while the radius of the second air hole gradually decreases.

[0012] According to a further technical solution, the surfaces of the heat dissipation plate and the heat dissipation groove are coated with hydrophilic or hydrophobic materials.

[0013] In summary, the embodiments of the present invention have the following beneficial effects compared with the prior art:

[0014] 1. The heat dissipation area is effectively increased through the heat dissipation grooves and heat dissipation plates, which promotes heat convection and accelerates the transfer of heat from the inside of the heat-conducting layer to the external environment. The heat-conducting layer uses a high thermal conductivity polymer to effectively improve the heat conduction efficiency, quickly transferring heat from the upper or lower mica sheet to the heat dissipation plate. The spoiler causes the fluid to be continuously disturbed and accelerated during the flow process, thereby improving the convection heat dissipation effect of the heat and quickly cooling the upper and lower mica sheets, thereby improving performance and service life.

[0015] 2. The first air hole and the second air hole gradually change in radius, so that the outside air can enter each heat dissipation slot without being blocked by the inner wall of the heat dissipation slot, thereby enhancing the heat dissipation effect.

[0022] In order to make the purpose, technical solutions and advantages of the present invention more clearly understood, the present invention is further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present invention and are not intended to limit the present invention.

[0023] The specific implementation of the present invention is described in detail below with reference to specific embodiments.

[0024] like Figure 1-4 As shown, an embodiment of the present invention provides a mica sheet with good heat dissipation effect, including a shell 1, an upper mica sheet 2 and a lower mica sheet 6, the upper end of the inner wall of the shell 1 is fixedly connected to the upper mica sheet 2, the lower end of the inner wall of the shell 1 is fixedly connected to the lower mica sheet 6, and the end surfaces of the upper mica sheet 2 and the lower mica sheet 6 close to each other are coated with a thermal conductive layer 12, and a heat dissipation plate 8 is fixed on the thermal conductive layer 12, and a plurality of evenly distributed heat dissipation grooves 7 are provided on the heat dissipation plate 8, and a plurality of spoilers 9 are fixedly arranged in each heat dissipation groove 7, and second air inlet slots 5 are provided on both side walls of the shell 1, and each end of the heat dissipation plate 8 close to the thermal conductive layer 12 is provided with a first air hole 10 and a second air hole 11, and a plurality of evenly distributed first air inlet slots 4 are also provided on both side walls of the shell 1, and the first air inlet slots 4 are connected to the corresponding first air hole 10 and second air hole 11.

[0025] Furthermore, the heat-conducting layer 12 is made of a highly thermally conductive polymer, thereby effectively improving the heat conduction efficiency and quickly conducting heat from the upper mica sheet 2 or the lower mica sheet 6 to the heat sink 8 .

[0026] Furthermore, the spoilers 9 in each heat dissipation slot 7 are arranged at an angle, and the spoilers 9 in the same heat dissipation slot 7 are not coplanar and intersect with each other. The presence of the spoilers 9 causes the fluid to be continuously disturbed and accelerated during the flow process, thereby improving the convection heat dissipation effect of heat.

[0027] Furthermore, a plurality of evenly distributed windless power caps 3 are fixedly provided on the other two side walls of the housing 1 . The windless power caps 3 adopt the existing technology and will not be described in detail here.

[0028] It is understood that the heat sink 7 and the heat sink 8 are an integrated structure. The working principle of the non-powered hood is mainly based on natural wind and the convection effect of indoor and outdoor air. As long as there is a temperature difference between indoor and outdoor (usually the temperature difference between indoor and outdoor exceeds 0.5°C), the non-powered hood can work through the thermal convection effect. The higher temperature indoor air will flow outward, driving the turbine inside the hood to rotate, thereby achieving indoor and outdoor air convection.

[0029] Further, such as Figure 3 and Figure 4As shown, the first air holes 10 and the second air holes 11 are arranged in a staggered manner. The first air holes 10 and the second air holes 11 are of the same size. The radius of the first air holes 10 gradually increases from one side of the heat sink 8 to the other side, while the radius of the second air holes 11 gradually decreases. The gradual change in radius of the first air holes 10 and the second air holes 11 allows external air to enter each heat sink 7 more effectively without being blocked by the inner wall of the heat sink 7, thereby enhancing the heat dissipation effect.

[0030] Furthermore, the surfaces of the heat sink 8 and the heat sink 7 are coated with hydrophilic or hydrophobic materials to improve the heat exchange efficiency with the cooling medium (such as air) and further enhance the heat dissipation performance.

[0031] Specifically, the heat dissipation area is effectively increased through the heat dissipation groove 7 and the heat dissipation plate 8, heat convection is promoted, and the transfer of heat from the inside of the heat-conducting layer 12 to the external environment is accelerated. The heat-conducting layer 12 adopts a high thermal conductivity polymer, thereby effectively improving the heat conduction efficiency, and quickly conducting heat from the upper mica sheet 2 or the lower mica sheet 6 to the heat dissipation plate 8. The spoiler 9 allows the fluid to be continuously disturbed and accelerated during the flow process, thereby improving the convection heat dissipation effect of heat, and quickly cooling the upper mica sheet 2 and the lower mica sheet 6, thereby improving performance and service life; the first air hole 10 and the second air hole 11 gradually change through the radius, so that the outside air can enter each heat dissipation groove 7 without being blocked by the inner wall of the heat dissipation groove 7, thereby enhancing the heat dissipation effect.

[0032] The working principle of the present invention is as follows: when the upper mica sheet 2 generates heat during operation, the heat will be efficiently transferred to the heat sink 8 in the heat sink 7 through the heat conductive layer 12. Subsequently, the high-temperature gas (mainly air heated by the heat on the heat sink 8) will be discharged outward through the second air inlet slot 5 and partially through the windless power cap 3. At the same time, when external wind blows towards the first air inlet slot 4 and the second air inlet slot 5, the air will enter the heat sink 7 through the first air inlet slot 4, and after being accelerated by the disturbance of the spoiler 9, it will carry the heat to the middle of the outer shell 1 and be discharged from the outer shell 1 through the second air inlet slot 5, thereby achieving effective heat dissipation and cooling of the device. In addition, part of the high-temperature gas will also enter the interior of the heat sink 7 through the guidance of the first air hole 10 and the second air hole 11, further enhancing the heat dissipation effect.

[0033] The circuits, electronic components and modules involved are all existing technologies and can be fully implemented by those skilled in the art. Needless to say, the content protected by this utility model does not involve improvements to software and methods.

[0034] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent replacements and improvements made within the spirit and principles of the present invention should be included in the scope of protection of the present invention.
