Summary of the invention
In view of this, be necessary that providing a kind of can improve the outer casing member of radiating efficiency and use the electronic installation of this outer casing member.
A kind of outer casing member, it comprises a housing, a heat dissipating layer and a cover glass.Described housing comprises an outer surface.Described heat dissipating layer is arranged on the outer surface of described housing, and described cover glass is arranged on described heat dissipating layer.The described heat dissipating layer of part exposes outwards to dispel the heat from described cover glass.The conductive coefficient of described heat dissipating layer is greater than described housing.
A kind of electronic installation, it comprises an outer casing member and as above and is housed in display screen in described outer casing member.
Outer casing member provided by the invention by arranging heat dissipating layer between housing and cover glass; conductive coefficient due to heat dissipating layer is greater than described housing; thus make the heat conducting to housing can enter this heat dissipating layer; and be rapidly to outer distributing by the part that heat dissipating layer exposes this cover glass, improve radiating effect.
Embodiment
As shown in Figure 1-2, a kind of electronic installation 100 that embodiment of the present invention provides, it multiple electronic component comprising an outer casing member 10 and be housed in described outer casing member 10, such as, display screen and circuit board.In present embodiment, described electronic installation 100 is a mobile phone.
Described outer casing member 10 comprises housing 11, heat dissipating layer 12, cover glass 13 and two optical cement layer 14.
Described housing 11 is in rectangular shape, and it adopts metal or plastic material to make.Described housing 11 comprises an outer surface 111.
The conductive coefficient of described heat dissipating layer 12 is greater than described housing 11.Described heat dissipating layer 12 is graphene film or carbon nano-tube film.Described graphene film and described carbon nano-tube film are the allotrope of carbon, described graphene film is that honeycomb lattice structure forms film, described carbon nano-tube film is by the film of multiple carbon nanotube arrangement, and these two kinds of films all have larger area of dissipation.Described heat dissipating layer 12 is transparent membrane, only absorb the light of about 2.3%, and conductive coefficient is about 5300W/mK, and has reelability.In present embodiment, the thickness of described heat dissipating layer 12 is about 100um-1000um.
Described cover glass 13 is in tabular, and it is toughened glass.Described cover glass 13 comprises upper surface 131 and a lower surface 132 relative with described upper surface 131.The case hardness of described upper surface 131 reaches 8-9H.Described lower surface 132 has nano level etching.The conductive coefficient of described cover glass 13 is about 1.1W/mK.In present embodiment, the thickness of described cover glass 13 is about 10um-150um.
Described optical cement layer 14 adopts and is formed by rigid optical glue.Described rigid optical glue is epoxy resin, and it has good translucent effect.
In the process of assembling, first on the outer surface 111 of described housing 11, apply one deck epoxy resin to form described optical cement layer 14, then be attached in described optical cement layer 14 by described heat dissipating layer 12, make described heat dissipating layer 12 mutually bonding with described housing 11.Then, described heat dissipating layer 12 applies one deck epoxy resin again to form another layer of optical cement layer 14, then the lower surface 132 of described cover glass 13 is attached to described optical cement layer 14, make described cover glass 13 mutually bonding with described heat dissipating layer 12.The described heat dissipating layer of part 12 exposes described cover glass 13.In present embodiment, the edge of described heat dissipating layer 12 is not coated by described cover glass 13 institute, thus described heat dissipating layer 12 is directly contacted with outside.Secondly, because described heat dissipating layer 12 has reelability, described cover glass 13 can effectively be fitted with described housing 11.Moreover, the lower surface 132 due to described cover glass 13 has nano level etching, make described cover glass 13 can with described housing 11 stable adhesion.
In the process used, on the heat conduction that described electronic installation 100 produces to described housing 11, because described heat dissipating layer 12 has higher conductive coefficient, thus make the heat on described housing 11 can conduct to described heat dissipating layer 12 rapidly.Further, due to the design feature of described heat dissipating layer 12, the heat on described heat dissipating layer 12 can be distributed rapidly.When there being External Force Acting on the upper surface 131 of described cover glass 13, on the one hand because described upper surface 131 has higher hardness, described cover glass 13 is not easily scratched; On the other hand, because described optical cement layer 14 adopts rigid optical glue to be formed, act on described cover glass 13 external force will absorb by described housing 11, thus make described cover glass 13 not easily broken.
Outer casing member provided by the invention by arranging heat dissipating layer between housing and cover glass; conductive coefficient due to heat dissipating layer is greater than described housing; thus make the heat conducting to housing can enter this heat dissipating layer; and be rapidly to outer distributing by the part that heat dissipating layer exposes this cover glass, improve radiating effect.
Be understandable that, for the person of ordinary skill of the art, other various corresponding change and distortion can be made by technical conceive according to the present invention, and all these change the protection range that all should belong to the claims in the present invention with distortion.
