[0022] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present utility model.

[0023] Please refer to Figures 1-3 , the present utility model provides a technical solution: a mobile phone graphite heat sink for preventing powder falling, including: heat sink body 1, graphite body 2, thermal conductive gasket 3, edge wrapping layer 4, protective layer 5, adhesive layer 6, positioning groove 7, connecting piece 8, adhesive piece 9.

[0024] First, as shown in Figure 1 , shown in Figure 2 , and shown in Figure 3As shown, it is adhered to the top of the heat sink body 1 through the graphite body 2, and a wrapping layer 4 is fixedly installed on the edge of the top of the heat sink body 1. At the same time, the height of the wrapping layer 4 is higher than that of the graphite body 2. Thus, the graphite body 2 can be blocked by the wrapping layer 4, and the falling of the graphite body 2 can also be prevented. Then, the protective layer 5 is set in a polyester material state. Thus, the bottom of the protective layer 5 can be adhered to the top of the wrapping layer 4. Then, with the protective layer 5 placed above the graphite body 2, the graphite body 2 can be enclosed through the mutual cooperation between the protective layer 5 and the heat sink body 1. Then, since the protective layer 5 is set in a polyester material state, and the polyester material has excellent transparency and heat resistance, the graphite body 2 on the top of the heat sink body 1 can be protected, and the integrity of the graphite body 2 can be ensured.

[0025] As shown in the attached Figure 2 and attached Figure 3 As shown, when installing the heat sink body 1, first, positioning grooves 7 are opened at both the upper and lower ends of the right end of the heat sink body 1, so that the positioning grooves 7 are engaged with the core component. At the same time, both the upper and lower ends of the adhesion layer 6 are set in a high-temperature double-sided adhesive state, and a connecting piece 8 is fixedly installed at the top of the right end of the adhesion layer 6. At the same time, an adhesion piece 9 is fixedly installed at the bottom of the connecting piece 8. Thus, the bottom of the adhesion piece 9 is adhered together. Then, through the positioning grooves 7, it is engaged with the core for guiding and positioning, so that the adhesion piece 9 is temporarily adhered to the core component, preventing displacement during the installation of the heat sink body 1. Then, a heat-conducting gasket 3 is fixedly installed at the bottom of the heat sink body 1, and both the upper and lower ends of the heat-conducting gasket 3 are in an adhered state. Thus, the heat-conducting gasket 3 can be adhered to the heat sink body 1, and at the same time, the bottom of the heat-conducting gasket 3 can be adhered to the core component of the mobile phone. Then, since the heat-conducting gasket 3 is set in a flexible adhesion state, the heat-conducting gasket 3 can provide good flexibility and heat conductivity. Thus, the heat-conducting gasket 3 is adhered to the heat sink body 1 and the core component. After the installation of the heat sink body 1 is completed, since the adhesion layer 6 is set in a double-sided adhesive state, the adhesion piece 9 can be pulled, so that the adhesion piece 9 is disengaged from the core component. At the same time, the adhesion piece 9 pulls out the covering surface on the surface of the adhesion layer 6 through the connecting piece 8 from the surface of the adhesion layer 6. Then, through the covering surface on the surface of the adhesion layer 6, the connecting piece 8 and the adhesion piece 9 are removed from the surface of the adhesion layer 6. Then, due to the adhesion effect of the adhesion layer 6, the adhesion layer 6 is connected and adhered to the cover plate of the core component. Thus, the adhesion layer 6 is adhered to the protective layer 5 and the mobile phone back cover, enabling the adhesion layer 6 to withstand high-temperature environments and ensuring that it is adhered to the components.
