Problems solved by technology

In the actual production process, graphite heat sinks with a thickness of 0.01-0.1mm are usually pasted on the surface of the working components of the product to achieve the purpose of heat conduction and heat dissipation. However, each product includes multiple working components. If each The surface of each working component is pasted with graphite heat sink, which not only increases the workload of the work, but also increases the production cost of the product due to the increase in the number of graphite heat sinks.
The distance between two adjacent working components is often greater than the thickness of a single graphite heat sink, so that there is a certain gap between two adjacent working components, so that the heat is suspended, which is not conducive to the timely dissipation of heat. If there are many above-mentioned gaps and heat suspension phenomena, it will affect the performance of the product, and even affect its service life

Abstract

The invention discloses a compressible artificial graphite sheet comprising a graphite substrate which is made of artificially synthesized graphite and is 0.1-0.35mm thick. The graphite substrate can be compressed according to various thickness demands, and the thickness of the graphite substrate after compression is 0.01-0.25mm. The graphite sheet not only is wide in application scope, but also can fill a gap between two adjacent working assemblies with the spacing of less than 0.3mm. By the adoption of the graphite sheet, the heat impending phenomenon is avoided, the two adjacent working assemblies are integrated, and the heat conductivity and the heat radiating property are further improved. For a gap between two adjacent working assemblies with the spacing of more than 0.35mm, the heat impending space can be reduced, the heat radiating quantity is increased, and the using property of a product is ensured.

Description

technical field [0001] The invention relates to the application field of heat conduction and heat dissipation materials, in particular to a compressible artificial graphite sheet for heat conduction and heat dissipation. Background technique [0002] In recent years, with the continuous development of electronic technology and the continuous updating 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. It is equipped with a corresponding heat dissipation device, and it is also necessary to ensure that the heat dissipation device has a stronger heat dissipation capacity, so as to ensure the reliability of product performance and prolong its service life. [0003] Graphite heat dissipation material, because of its unique low density (compared to metals), high thermal conductivity and heat dissipation coefficient and low thermal resis...
