Abstract
A kind of synthetic graphite fin of sandwich structure, including double coated film, compound stone ink sheet and electric insulating film are the utility model is related to, compound stone ink sheet is arranged between double coated film and electric insulating film and by double coated film and electric insulating film environmental sealing.The utility model is by the way that graphite heat radiation fin is sandwiched structure, solve the problems, such as that broken drop easily occurs compound stone ink sheet for graphite in use well, so as to reduce the potential safety hazard of electronic product, the good mouldability of compound stone ink sheet is also gived, improves the use range of graphite heat radiation fin.
Description
Technical field
The utility model belongs to the technical field of graphite radiating, is dissipated more particularly to a kind of synthetic graphite of sandwich structure
Backing.
Background technology
Constantly bringing forth new ideas and develop with science and technology, the living standard of people are improved constantly, and each electronic product is also rapidly sent out
Exhibition.With increasing for function, the wasted work of electronic product is consequently increased, and the chip CPU of PC, mobile phone etc. temperature is also with computing
Being multiplied for speed and be substantially increased.It is well known that the operating temperature of electronic component directly determines its service life and stably
Property, to allow the operating temperature of each part such as mobile phone to be maintained in rational scope, strengthen heat dissipation problem and do not allow to avoid.Fin is
Presently the most effective radiating mode, as market occurs in succession for the wilderness demand of fin, all kinds of fin.Graphite dissipates
Backing is also referred to as conductive graphite piece, is a kind of heat conduction and heat radiation material, has unique crystal grain orientation, along both direction uniform heat conduction,
It is laminar structured to be well adapted for any surface, shielding thermal source and the performance that consumer electronics product is improved while component.
Why graphite heat radiation fin can be designed to, be the plasticity that make use of graphite, graphite material made one piece thin as paster
Piece, allow it to be attached to the circuit board top of interior of mobile phone, can both obstruct the contact between original paper, certain resist can also be played
Shake acts on.
But presently commercially available various ultra-thin, soft graphite fin, due to ultra-thin and its pliability, cause shaping to add
Work is difficult, and the problem of graphite falls chip be present.
The content of the invention
Technical problem to be solved in the utility model is to provide a kind of synthetic graphite fin of sandwich structure, solves
Synthetic graphite is fragile in use to go to sticks and staves the problem of considering the problem of producing hidden danger and mouldability to be worth doing.
Technical scheme is to provide a kind of compound stone of sandwich structure used by the utility model solves its technical problem
Black fin, including double coated film, compound stone ink sheet and electric insulating film, the compound stone ink sheet are arranged at double coated film and electricity
Between insulation film and pass through double coated film and electric insulating film environmental sealing.
As a kind of preferred embodiment of the utility model, the lateral edge of the compound stone ink sheet is thin by being electrically insulated
Film wraps up.
As the utility model another preferred embodiment, the double coated film is made of acrylic acid.
As the utility model another preferred embodiment, the compound stone ink sheet uses artificial synthesized graphite system
Into.
As the utility model another preferred embodiment, the electric insulating film uses poly terephthalic acid second two
Alcohol ester is made.
Beneficial effect
The utility model is by the way that graphite heat radiation fin is sandwiched structure, and compound stone ink sheet is by double coated film and electric insulation
Film environmental sealing, solve the problems, such as that graphite flake is easily broken in use well and drop, so as to reduce electronics
The potential safety hazard of product, the good mouldability of graphite flake is also gived, improve the use range of graphite heat radiation fin.
Brief description of the drawings
Fig. 1 is cross section structure schematic diagram of the present utility model.
Embodiment
With reference to specific embodiment, the utility model is expanded on further.It should be understood that these embodiments are merely to illustrate this
Utility model rather than limitation the scope of the utility model.In addition, it is to be understood that reading the content of the utility model instruction
Afterwards, those skilled in the art can make various changes or modifications to the utility model, and these equivalent form of values equally fall within this Shen
Please appended claims limited range.
A kind of synthetic graphite fin of sandwich structure as shown in Figure 1, including double coated film 1, the and of compound stone ink sheet 2
Electric insulating film 3.
Compound stone ink sheet 2 is arranged between double coated film 1 and electric insulating film 3, and by double coated film 1 and is electrically insulated thin
The environmental sealing of film 3, the lateral edge of compound stone ink sheet 2 are wrapped up by electric insulating film 3.Double coated film 1 is made of acrylic acid,
Graphite can be clung securely.Compound stone ink sheet 2 uses artificial synthesized graphite, and electrographite piece can be accomplished to compare natural graphite flakes
It is thinner, and thermal conductivity factor is also higher than natural graphite flakes.Electric insulating film 3 is made of polyethylene terephthalate,
Electric current can be completely cut off very well, protective effect well is played to synthesis graphite flake 2.
By the way that graphite heat radiation fin is sandwiched structure, solves the stone in use of compound stone ink sheet 2 well
It is black that broken the problem of dropping easily occurs, so as to reduce the potential safety hazard of electronic product, it is fine to also give compound stone ink sheet 2
Mouldability, improve the use range of graphite heat radiation fin.
