Abstract
The invention discloses a novel artificial graphite flake. One side of the artificial graphite flake is plated with a nickel layer by electroless plating, and one side of the nickel layer is plated with a copper layer by electroless plating. By the electroless plating mode, the artificial graphite flake is firstly plated with the nickel layer, and then the nickel layer is plated with the copper layer. Thus, thermal conductivity of the artificial graphite flake in the thickness direction is enhanced, and thermal conductivity of copper in the plane direction is also improved. Heat conduction of the artificial graphite flake in each direction tends to be balanced, and uniform and good heat conduction and heat radiation effects are achieved.
Description
Technical field
Heat Conduction Material application, particularly a kind of novel artificial graphite flake the present invention relates to dispel the heat.
Background technology
In recent years, along with the development of electronic technology, electronic product is constantly updated and is regenerated, the size of its work package is more and more less, speed and the efficiency of work are more and more higher, and its caloric value is also increasing, therefore not only requires it to be equipped with corresponding heat abstractor, also to guarantee that heat abstractor has stronger heat-sinking capability, to ensure the reliability of properties of product and to extend its useful life.
Graphite radiating Heat Conduction Material, because its distinctive low-density (with respect to metal species) and high heat radiation conductive coefficient and low thermal resistance become hyundai electronics series products and solve the preferred material of heat radiation heat conduction technology.Graphite heat radiation fin can be along in-plane heat conduction, all right through-thickness heat conduction, and a little less than thickness direction heat conduction, metal material is copper such as, heat conduction than graphite heat radiation fin in-plane a little less than, and stronger than graphite heat radiation fin thickness direction, therefore, a kind of new material that had not only strengthened the thermal conductivity of graphite heat radiation fin thickness direction but also strengthened copper in-plane thermal conductivity urgently occurs.
Summary of the invention
For solving the problems of the technologies described above, a kind of novel artificial graphite flake provided by the invention, to reach the object that not only strengthens the thermal conductivity of graphite heat radiation fin thickness direction but also strengthen copper in-plane thermal conductivity.
For achieving the above object, technical scheme of the present invention is as follows:
A kind of novel artificial graphite flake, the one side chemistry of described electrographite sheet is coated with a nickel dam, and the one side chemistry of described nickel dam is coated with a bronze medal layer.
Preferably, the another side of described electrographite sheet is pasted with a film.
Pass through technique scheme, novel artificial graphite flake provided by the invention, by the mode of chemical plating, first electrographite sheet is plated to a nickel dam, nickel dam is being plated to a bronze medal layer, both strengthening the thermal conductivity of electrographite sheet thickness direction, strengthening again copper in-plane thermal conductivity, make the heat conduction of these novel artificial graphite flake all directions be tending towards balanced, reach evenly good heat conduction and heat radiation effect.

Embodiment
Below in conjunction with the accompanying drawing in the embodiment of the present invention, the technical scheme in the embodiment of the present invention is clearly and completely described.
A kind of novel artificial graphite flake provided by the invention; as shown in Figure 1, the one side chemistry of electrographite sheet 1 is coated with a nickel dam 2, and the one side chemistry of nickel dam 2 is coated with a bronze medal layer 3; the another side of electrographite sheet 1 is pasted with a film 4, and film 4 plays the effect of protection electrographite sheet 1.
Coating mode described in above-described embodiment is not defined as chemical plating, also can adopt the mode coating such as plating, and the embodiment of the present invention is not done any restriction.
A kind of novel artificial graphite flake disclosed by the invention, by the mode of chemical plating, first electrographite sheet is plated to a nickel dam, nickel dam is being plated to a bronze medal layer, both strengthened the thermal conductivity of electrographite sheet thickness direction, strengthen again copper in-plane thermal conductivity, made the heat conduction of these novel artificial graphite flake all directions be tending towards balanced, reached evenly good heat conduction and heat radiation effect.
To the above-mentioned explanation of the disclosed embodiments, make professional and technical personnel in the field can realize or use the present invention.To be apparent for those skilled in the art to the multiple amendment of these embodiment, General Principle as defined herein can, in the situation that not departing from the spirit or scope of the present invention, realize in other embodiments.Therefore, the present invention will can not be restricted to these embodiment shown in this article, but will meet the widest scope consistent with principle disclosed herein and features of novelty.
