Embodiment 1

[0033] (1) The back cover body is made of aluminum alloy material, and the honeycomb-shaped small holes with a diameter of 1 mm and a draft angle of 10 degrees are set on the back cover body, and the distance between the centers of adjacent small holes is 2 mm.

[0034] (2) The ultrafiltration membrane is made of polyacrylonitrile (PAN), the thickness of the film is 300 microns, the diameter of the pores on the film is circular, and the diameter is 0.15 microns.

[0035] (3) Use 0.4mm thick and 1mm wide silver strips to weave into a silver screen with 16 meshes and 1 mm aperture. The area of ​​the silver screen is 0.5 mm wider than the inner wall of the back cover body.

[0036] (4) Clean the inner surface of the back cover body first, then evenly apply 502 adhesive to the four corners of the inner surface of the back cover body and the corresponding parts of the ultrafiltration membrane, and then tightly bond the ultrafiltration membrane to the back cover body The inner surfa...

Embodiment 2

[0038] (1) Using a mold, the back cover body is processed by injection molding from a polycarbonate composition, and honeycomb-shaped small holes with a diameter of 1.5 mm and a draft angle of 5 degrees are formed on it, and the center-to-center distance between adjacent small holes is 3 mm;

[0039] (2) The ultrafiltration membrane is made of polyvinyl chloride (PVC), the thickness of the membrane is 0.3 mm, the diameter of the pores on the membrane is circular, and the diameter is 0.15 microns.

[0040] (3) Use 0.4mm thick and 2mm wide silver strips to weave into a 32-mesh drying net with an aperture of 0.5mm. The area of ​​the drying net is 0.5mm wider than the inner wall of the back cover body.

[0041] (4) Pre-treat the four corners of the inner surface of the cleaned back cover body with a heat welding gun at a temperature of 240-270°C for 1-5 minutes; Apply polycarbonate solvent glue evenly on the parts, then tightly bond the ultrafiltration membrane to the inner surfa...

Abstract

The invention provides a mobile phone back cover capable of radiating. The mobile phone back cover comprises a back cover body, wherein a ultra-filtration membrane and a silver sunning net are orderly arranged on the inner wall of the back cover body; and cellular holes are formed on the back cover body to enable the internal of the mobile phone to produce conduction with the external to facilitate the air circulation, the heat is taken away, and the radiating function of the mobile phone is improved; furthermore, the drafting type cellular holes prevent the external dust and liquid from directly entering the mobile phone through the cellular holes, but enable the dust and the liquid to fall on the hole wall as much as possible, thereby effectively protecting the internal electron components of the mobile phone. The ultra-filtration membrane not only enables the air convection, but also effectively prevents the dust and liquid entering through the cellular holes on the mobile phone back cover body from entering the internal of the mobile phone, thereby effectively protecting the internal electron components of the mobile phone.

Description

technical field [0001] The invention relates to the communication field, in particular to a back cover for a heat-dissipating mobile phone. Background technique [0002] With the continuous and rapid development of the level of science and technology, mobile phones are becoming more and more intelligent and mobile terminalized, and many functions of the past computer are given to mobile phones. To meet these advanced requirements, mobile phones are equipped with more and more high-performance electronic components, such as multi-core central processing units / CPUs for faster operation, large-capacity memory, and graphics processing for high-quality display functions. processor / GPU, etc., but these electronic components are getting hotter and hotter. The heating of electronic components not only affects the performance of the time, but also seriously affects the service life of the components. [0003] Since the mobile phone is a small carrier, it is limited that it cannot...
