Abstract
The invention discloses a graphite heat-conducting flake. The graphite heat-conducting flake comprises a graphite flake layer and a lining layer, wherein the graphite flake layer and the lining layer are bonded and fixed together through a double-side tap layer, a film layer is coated on the upper surface of the graphite flake layer, and the edge positions of the graphite flake layer, the double-side tap layer and the film layer are the same. By means of the method, the graphite heat-conducting flake can ensure that the graphite in the graphite heat-conducting flake delaminates and the edge of the graphite is complete, avoids the bad phenomenon of powder falling, guarantees the heat-conducting effect, and prolongs the service life.
Description
Technical field
The present invention relates to the graphite field, particularly relate to a kind of graphite heat-conducting fin.
Background technology
Native graphite belongs to hexagonal crystal system, and the netted surface ga(u)ge of hexagonal that its crystal is comprised of carbon atom is then piled up and formed, and has layer structure.In every one deck, carbon atom is even must to be arranged in hexagon, and the crystal structure of this uniqueness causes its heat transmission mainly to concentrate on both direction: X-Y axle and Z axis.The conductive coefficient of X-Y axle is 300-1500W/mk, and the conductive coefficient of Z axis is about 8-15W/mK.
In consumer electronics today under the development trend of ultrathin, intellectuality and multifunction, power day by day increase and product do thinner and thinner day by day to show the problem that heat is dispersed. because of its in the outstanding characteristic aspect the heat conduction, graphite heat-conducting fin has received increasing concern, is having a wide range of applications aspect smart mobile phone, ultra-thin PC and LED TV etc.
There are the bad generations such as dry linting at graphite laminated in the existing graphite heat-conducting fin and graphite edge, affect the heat-conducting effect of conducting strip.
Summary of the invention
The technical problem that the present invention mainly solves provides a kind of graphite heat-conducting fin, can guarantee that graphite laminated and graphite edge in the graphite heat-conducting fin are complete, solve the bad phenomenon such as dry linting, guaranteed the heat-conducting effect of graphite heat-conducting fin, prolonged the useful life of graphite heat-conducting fin.
For solving the problems of the technologies described above, the technical scheme that the present invention adopts is: a kind of graphite heat-conducting fin is provided, comprise graphite flake layer and laying, described graphite flake layer and laying are adhesively fixed by layers of two-sided, described graphite flake layer upper surface is coated with rete, and the marginal position of described graphite flake layer, layers of two-sided and rete is identical.
Preferably, described layers of two-sided is high temperature resistant layers of two-sided.
Preferably, described rete is high temperature resistant rete.
The invention has the beneficial effects as follows: a kind of graphite heat-conducting fin of the present invention, can guarantee that graphite laminated and graphite edge in the graphite heat-conducting fin are complete, solve the bad phenomenon such as dry linting, guaranteed the heat-conducting effect of graphite heat-conducting fin, prolonged the useful life of graphite heat-conducting fin.
