Embodiment Construction

[0015] see Figure 1-Figure 2 As shown, the technical solution adopted in this specific embodiment is: it is made up of metal shell 1, upper graphite layer 2, adhesive tape 3, lower graphite layer 4, protective film 5, and its preparation method is: first upper graphite layer 2 and The lower graphite layer 4 is pasted and stacked together by the adhesive tape 3; then the protective film 5 is completely wrapped around the upper graphite layer 2 and the lower graphite layer 4; finally, the metal shell 1 is completely wrapped around the graphite layer 2 and the lower graphite layer 4.

[0016] The metal casing 1 is uniformly provided with cooling holes 6 . The function of the heat dissipation holes 6 is to discharge the heat absorbed by the graphite to the outside.

[0017] The metal shell 1 is made of one metal or multiple metal alloys among iron, copper, aluminum, tin, nickel, gold, silver, lead and zinc. These metal materials are very common in real life, and the cost is rel...

Abstract

The invention discloses a novel graphite sheet and a preparation method thereof, relates to the field of heat dissipation and heat conduction material applications, in particular to a novel graphite sheet and a preparation method thereof. The novel graphite sheet comprises a metal housing (1), an upper graphite layer (2), an adhesive tape (3), a lower graphite layer (4) and a protective film (5);and the preparation method comprises the steps of firstly pasting and superposing the upper graphite layer (2) and the lower graphite layer (4) together through the adhesive tape (3); completely wrapping the upper graphite layer (2) and the lower graphite layer (4) with the protective film (5); and finally completely wrapping the upper graphite layer (2) and the lower graphite layer (4) with the metal housing (1). After the technical scheme is adopted, the novel graphite sheet has the beneficial effects that the novel graphite sheet is simple in structure and convenient to produce, furthermore, the graphite sheet can be well protected and the heat dissipation performance of the graphite sheet is improved.

Description

technical field [0001] The invention relates to the application field of heat dissipation and heat conduction materials, in particular to a novel graphite sheet and a preparation method thereof. Background technique [0002] Graphite sheet is a brand-new heat conduction and heat dissipation material, which conducts heat evenly in two directions, shields heat sources and components, and improves the performance of consumer electronics products. With the acceleration of the upgrading of electronic products and the increasing demand for thermal management of miniature, highly integrated and high-performance electronic equipment, graphite thermal pads have received more and more attention because of their outstanding characteristics in thermal conductivity. Mobile phones, ultra-thin PCs and LED TVs have a wide range of applications. However, the existing graphite sheet is generally designed as a single piece, the structure is very thin, easy to break, and the heat dissipation e...
