[0024] It should be noted that, in the absence of conflict, the embodiments and features in the embodiments of the present application can be combined with each other. Now, in conjunction with the accompanying drawings, a preferred embodiment of the present utility model is described in detail.
[0025] The utility model provides a heat dissipation protective shell, such as Figure 1 to Figure 2 As shown, the heat dissipation protective shell includes a shell 1, a first heat-conducting member 2 and a second heat-conducting member 3 for heat dissipation; a mounting cavity 11 for mounting an electronic device is formed on the shell 1, a through hole 12 is formed on the back of the shell 1, the through hole 12 is connected to the mounting cavity 11, and the second heat-conducting member 3 is arranged in the mounting cavity 11 and covers the through hole 12; the first heat-conducting member 2 is located in the through hole 12 and is attached to a surface of the second heat-conducting member 3 facing away from the mounting cavity 11.
[0026] The heat dissipation protection shell of the utility model is provided with a first heat conductive member 2 and a second heat conductive member 3, and a through hole 12 is provided on the back of the shell 1, the second heat conductive member 3 covers the through hole 12 on one side of the installation cavity 11, and the first heat conductive member 2 is attached to the side of the second heat conductive member 3 away from the installation cavity 11 through the through hole 12. In actual use, the second heat conductive member 3 can more directly conduct heat to the electronic equipment installed in the installation cavity 11, and can directly conduct heat to the first heat conductive member 2, and the opening of the through hole 12 not only realizes the internal and external connection and attachment of the first heat conductive member 2 and the second heat conductive member 3, but also removes the heat blocking of the shell 1, and the complete heat conduction path can transfer heat to the external environment faster, so that the heat conduction speed of the heat dissipation protection shell is fast, the efficiency is high, and the heat conduction effect is good.
[0027] The first heat conductor 2 and the second heat conductor 3 can be made of materials with good thermal conductivity. Specifically, the first heat conductor is an aluminum sheet. The aluminum sheet has excellent thermal conductivity, which helps to quickly and effectively conduct heat from the electronic device to the external environment of the heat dissipation protective shell. The aluminum sheet also has a lower density, which can reduce the weight of the overall heat dissipation protective shell, which is conducive to the lightweight design of the product. In addition, the aluminum sheet has good corrosion resistance, can maintain stable performance under various environmental conditions, and extend the service life of the heat dissipation protective shell. Since aluminum materials are usually inexpensive and easy to process, selecting aluminum sheets can reduce manufacturing costs and is conducive to product cost control. The second heat conductor 3 can be a copper sheet. Copper has higher thermal conductivity than aluminum, which helps to further improve the heat dissipation efficiency. Copper also has good electrical conductivity, which is conducive to rapid heat conduction. In addition, copper is more heat-resistant than aluminum, so it can maintain stable performance in a high temperature environment. Selecting a copper sheet as the second heat conductor 3 can also increase the stability and reliability of the overall heat dissipation.
[0028] Furthermore, the heat dissipation protective shell also includes a third heat-conducting member 4 for heat conduction, and the third heat-conducting member 4 is arranged in the mounting opening 11 and covers the second heat-conducting member 3. The arrangement of the third heat-conducting member 4 can further increase the heat dissipation of the heat dissipation protective shell, thereby improving the heat conduction and heat dissipation efficiency. By covering the second heat-conducting member 3 and improving the adhesion to the back of the electronic device, more heat can be effectively conducted and dissipated to the external environment. The arrangement of the third heat-conducting member 4 can optimize the heat transfer path, ensure that heat is conducted from the internal equipment or components to the outside of the heat dissipation protective shell more quickly and evenly, and improve the overall heat dissipation efficiency.
[0029] Specifically, the third heat-conducting member 4 is a graphene sheet. The graphene sheet has excellent thermal conductivity and can effectively conduct and dissipate heat, thereby further improving the heat dissipation efficiency. Graphene also has excellent mechanical properties and stability, can work stably in harsh environments such as high temperature, and improve the durability and stability of the heat dissipation protective shell. In addition, graphene has a lower density and higher strength, which can reduce the overall weight of the heat dissipation protective shell and improve the lightweight design of the heat dissipation protective shell.
[0030] A first arc-shaped notch 5 is provided at a corner where the third heat-conducting member 4 and the second heat-conducting member 3 overlap. Figure 4 The right-angled notch 7 shown in the figure has an arc-shaped first arc-shaped notch 5 at a corner where the third heat-conducting member 4 and the second heat-conducting member 3 overlap, ensuring a sufficient coverage area, allowing the third heat-conducting member 4 and the second heat-conducting member 3 to correspond to the batteries of most electronic devices, while saving materials for the third heat-conducting member 4 and the second heat-conducting member 3 and reducing costs. Specifically, the third heat-conducting member 4 and the second heat-conducting member 3 are rectangular sheet structures with a first arc-shaped notch 5 at one corner.
[0031] Furthermore, the heat dissipation protective shell further includes a magnetic attracting ring 6, which is mounted on the side of the first heat conducting member 2 away from the mounting opening 11. The arrangement of the magnetic attracting ring 6 can facilitate the magnetic attraction and fixation of the heat dissipation protective shell on the external device, and also facilitate accurate magnetic alignment with the wireless charging plate during wireless charging, thereby improving the charging efficiency. Specifically, as Figure 3 As shown, a mounting groove 21 is provided on the side of the first heat conducting member 2 facing away from the mounting opening 11, and the magnetic coil 6 is installed in the mounting groove 21. By providing the mounting groove 21 on the back of the heat conducting member, the magnetic coil 6 can be installed more stably, so that the magnetic coil 6 and the heat conducting member are more tightly combined, ensuring that their positions are accurate and stable. This helps to prevent the magnetic coil from shifting or falling off during operation, thereby ensuring the stability and reliability of heat dissipation. Specifically, the magnetic coil 6 is in a ring shape, and the mounting groove 21 is also in a ring shape. The magnetic coil 6 can be fixed in the mounting groove 21 by glue or the like.
[0032] The thickness of the graphene sheet is 0.045mm to 0.085mm, and the thickness of the copper sheet is 0.3mm to 0.8mm. For the graphene sheet, the thinner design range (0.045mm to 0.085mm) is conducive to improving the heat conduction efficiency and lightweight, so that it can quickly conduct heat and is suitable for situations with limited space. The moderate thickness range of the copper sheet (0.3mm to 0.8mm) provides good heat conduction and structural support. Within this range, the copper sheet can absorb and dissipate a large amount of heat, which helps to reduce the temperature of electronic equipment and keep the heat dissipation effect stable. By reasonably controlling the thickness of the graphene sheet and the copper sheet, the heat dissipation protective shell can achieve better heat dissipation performance and maintain structural stability. Specifically, the thickness of the graphene sheet can be any of 0.045mm, 0.050mm, 0.055mm, 0.060mm, 0.065mm, 0.070mm, 0.075mm, 0.080mm, and 0.085mm. The thickness of the copper sheet may be any one of 0.3 mm, 0.4 mm, 0.5 mm, 0.6 mm, 0.7 mm, and 0.8 mm.
[0033] The copper sheet is attached to the installation cavity 11 by means of a thermally conductive double-sided adhesive, the graphene sheet is glued to the copper sheet, and the aluminum sheet is attached to the copper sheet by means of a thermally conductive double-sided adhesive. The copper sheet, as a heat conduction medium, is attached to the installation cavity by means of a thermally conductive double-sided adhesive, which helps to quickly conduct heat while being fixed and improves heat dissipation efficiency. The graphene sheet is adhered to the copper sheet, and because graphene has excellent thermal conductivity, it can further enhance the heat conduction efficiency and improve heat dissipation performance. As another part of the heat dissipation protective shell, the aluminum sheet is connected to the copper sheet by means of a thermally conductive double-sided adhesive, which helps to improve the stability and heat transfer of the overall heat dissipation structure, thereby improving the reliability and efficiency of the overall heat dissipation. This layered design can make full use of the characteristics of different materials, achieve an optimized heat dissipation effect, and ensure that the equipment can work stably and efficiently. Specifically, the thickness of the double-sided adhesive is 0.08mm to 0.12mm. For example, the thickness of the double-sided tape may be any one of 0.08 mm, 0.085 mm, 0.09 mm, 0.095 mm, 0.1 mm, 0.105 mm, 0.11 mm, 0.115 mm, and 0.12 mm.
[0034] Furthermore, the heat dissipation protective shell also includes an active heat dissipation element, which is installed on the back of the shell to actively dissipate heat for the shell. The active heat dissipation element can be a fan, etc. Active heat dissipation through active heat dissipation elements such as fans can quickly take away heat, greatly improving the heat dissipation effect of the heat dissipation protective shell.
