Embodiment 1

[0017] A kind of edge-wrapped graphite sheet provided by the invention, such as figure 1 As shown, it includes a graphite substrate 1, the four corners of the two sides of the graphite substrate 1 are provided with metal frames 2, and the graphite substrate 1 is an artificial graphite sheet. The metal frame can be made of copper or aluminum.

Embodiment 2

[0019] A kind of edge-wrapped graphite sheet provided by the invention, such as figure 2 As shown, a graphite substrate 1 is included, and the four sides of the two sides of the graphite substrate 1 are provided with metal frames 2, and the graphite substrate 1 is an artificial graphite sheet. The metal frame can be made of copper or aluminum.

[0020] An edge-wrapped graphite sheet disclosed in the present invention is provided with a metal frame on the four corners or four sides of one side of the graphite substrate. Since the thermal conductivity and heat dissipation of the graphite sheet are higher than that of the metal material, the heat can be more concentrated by the exposed graphite substrate. It can reduce the emission from the metal frame, so as to ensure the use function of its surrounding objects without affecting its heat conduction and heat dissipation performance, and bring great convenience to the enterprise. At the same time, a metal frame can also be provi...

Abstract

The invention discloses an overlapping graphite sheet including a graphite substrate. Four corners or edges at a side of the graphite substrate are provided with a metal frame. As heat conduction and dissipation properties of the graphite sheet is higher than metal materials, the arrangement of the metal frame at the four corners or edges at the side of the graphite substrate allows the heat to be dissipated in a more focused manner from the exposed graphite substrate, the dissipation from the metal frame is reduced, therefore the use function of surrounding objects is ensured without affecting the heat conduction and dissipation properties of the graphite sheet, and great convenience is brought to companies.

Description

technical field [0001] The invention relates to the application field of heat conduction and heat dissipation materials, in particular to an edge-wrapped graphite sheet. Background technique [0002] In recent years, with the continuous development of electronic technology and the continuous upgrading of electronic products, the size of its working components is getting smaller and smaller, the speed and efficiency of work are getting higher and higher, and its heat generation is also increasing. Therefore, it is often Graphite heat sink is used as the first choice material to solve the heat conduction and heat dissipation of electronic products. [0003] Graphite heat sink not only has good heat conduction and heat dissipation performance, but also has relatively uniform heat dissipation, which is bound to have a certain impact on the objects around the graphite heat sink, which is more likely to affect the use of surrounding objects, and even shorten the service life of su...
