The heat conducting fin made of metal is directly used for heat dissipation, although the heat transfer efficiency is high, in the heat conducting fin made of metal, although the arrangement of internal crystal particles is relatively orderly, the heat conducting fin still has the disorder of heat transfer in the heat transfer process, namely, the heat of a heat generating component is led out and is simultaneously spread on the surface contacting the heat generating component, and the heat is spread to a region with less heat generation, so that the temperature of the whole space is increased, and the work of other components is influenced, therefore, the heat dissipation of the existing high-heat-generation product does not directly use metal heat dissipation fins.

The heat-conducting layer 2 of 30-100nm graphite is deposited on the heat-conducting sheet matrix 1, and a specific deposition technology is a conventional technology, and no specific technology is applied in the application, so that all technologies capable of depositing the graphite heat-conducting layer on the heat-conducting sheet matrix can be applied, and the applicant does not need to describe in detail herein.
In other embodiments of the present application, graphene may be used in place of graphite for depositing the graphene thermal conductive layer.
Deposit metal deposition layer 3 on the graphite heat-conducting layer, in the technical scheme of this application, the metal element of metal deposition layer can also be different with the element of conducting strip base member is the same, and this place can choose as required, and in the technical scheme of this application, the preparation technique of metal deposition layer is current conventional technique also.
The outer surface of the metal deposition layer is coated with an alumina film layer 4, and in other embodiments of the present application, other heat conducting film layers can be selected.
The thickness of the graphite heat conduction layer is larger than that of the metal deposition layer.
