Novel graphite composite metal material

Abstract

The invention discloses a novel graphite composite metal material which comprises metallic matrixes and artificial graphite sheets. The metallic matrixes are machined into powder. The artificial graphite sheets are smashed into powder through a smasher. The artificial graphite sheets and the metallic matrixes are mixed sufficiently. The mixture of the artificial graphite sheets and the metallic matrixes are heated until the metallic matrixes are in a melting state, and then the mixture is cooled. The metal materials of the metallic matrixes comprise silver, copper, aluminum, iron, steel and alloy of silver, copper, aluminum, iron and steel. According to the novel graphite composite metal material, the artificial graphite sheets and the metallic matrixes are mixed sufficiently so as to form a novel composite material. The inside and all the surfaces of the novel composite material have the heat-conducting and heat-dissipating performance of the artificial graphite sheets, so that the heat-conducting and heat-dissipating performance of the novel composite material is improved, and heat inside a product can be dissipated timely and effectively. Consequently, the performance stability of the product is ensured. Due to the even distribution of the artificial graphite sheets, the novel composite material is even and stable in heat-conducting and heat-dissipating performance, and a satisfactory effect can be achieved.

Description

technical field [0001] The invention relates to the application field of composite metal materials, in particular to a novel graphite composite metal material 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 conduction and heat dissipation materials, because of their unique low density (compared to metals), high thermal conductivity and heat dissipation coefficient, and low thermal r...

Problems solved by technology

However, the shells of commonly used heat sinks are mostly made of metal materials, such as copper or aluminum, and the thermal conductivity and heat dissipation of these metal materials are worse than graphite heat sinks, which cannot satisfy the internal heat of the product from the shell in a timely manner. In order to prevent the continuous accumulation of heat inside the product, if the time is too long, it will have a certain impact on the performance of the product

In the prior art, there are also some improvement measures such as pasting graphite heat sinks on the inner surface of the metal shell. Although this method can guide the heat inside the product to the shell, it does not change the heat dissipation performance of the shell, and the heat still exists. The interior of the product cannot achieve a satisfactory improvement effect
