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
The present invention relates to composite material application, the novel graphite composite material that particularly a kind of heat conduction and heat radiation is used.
Background technology
In recent years, development along with electronic technology, electronic product is constantly updated and is regenerated, the size of its work package is more and more less, speed and the efficiency of work are more and more higher, and its caloric value is also increasing, therefore not only require it to be equipped with corresponding heat abstractor, also to guarantee that heat abstractor has stronger heat-sinking capability, to guarantee the reliability of properties of product and to extend its service life.
Graphite heat conducting heat sink material, because its distinctive low-density (with respect to metal species) and high heat conduction and heat radiation coefficient and low thermal resistance become the preferred material that hyundai electronics series products solves heat conduction and heat radiation technology, graphite heat radiation fin is heat conduction and heat radiation along the horizontal, vertical directions, the laminar structured surface that can adapt to better any product.Yet, the shell of at present conventional heat abstractor adopts metal material more, as copper or aluminium etc., and the heat conduction and heat radiation of these metal materials is poorer than graphite heat radiation fin, the heat that can not meet interiors of products is derived and is left by shell place timely, caused the continuous accumulation of interiors of products heat, overlong time, can have a certain impact to the performance of product.In prior art, also exist some such as paste the corrective measures such as graphite heat radiation fin on the inner surface of metal shell, although the method can be directed to shell place by the heat of interiors of products, but do not change the heat dispersion of shell, still there is the inside of product in heat, does not reach satisfied improvement effect.
Summary of the invention
For solving the problem existing in above-mentioned background technology, the object of the present invention is to provide a kind of novel graphite composite material, to reach acquisition advanced composite material (ACM), and improve the object of its heat conduction and heat radiation performance.
For achieving the above object, technical scheme of the present invention is as follows:
