Graphite sheet knowledge
Graphite sheet is a new kind of heat conduction and heat dissipation material, which can conduct heat evenly in two directions, shield heat sources and components, and improve the performance of consumer electronic products. With the acceleration of the upgrading of electronic products and the growing demand for heat management of mini, high integration and high-performance electronic equipment, our company has launched a new heat dissipation technology for electronic products, that is, a new solution for graphite heat dissipation. This new natural graphite solution has the advantages of high heat dissipation efficiency, small space occupation, light weight, uniform heat conduction along two directions, eliminating “hot spot” areas, shielding heat sources and components, and improving the performance of consumer electronic products. The main uses of graphite sheet are as follows: It is used in notebook computer, high power LED lighting, flat panel display, digital camera, mobile phone and personal assistant equipment. The heat dissipation principle of graphite fin heat dissipation technology is as follows: The important function of graphite sheet is to create a large effective area on which heat is transferred and taken away by external cooling medium. Graphite heat sink is through the uniform distribution of heat in the two-dimensional plane, so as to effectively transfer heat, to ensure that the components work under the temperature. Product features: the surface can be combined with metal, plastic, self-adhesive and other materials, more design functions and needs. Excellent thermal conductivity: 150-1200w / m.k, better than that of metal. Light weight, specific gravity only 1.0-1.3, soft, easy to operate. Low thermal resistance. The color is black. Thickness: 0.012-1.0mm, adhesive: 0.03mm, thermal conductivity: plane conduction: 300-1200w / m.k, vertical conduction: 20-30w / M.K. temperature resistance: 400 ℃. Low thermal resistance: 40% lower than aluminum and 20% lower than copper; Light weight: 25% lighter than aluminum and 75% lighter than copper. And according to the needs of customers to do any form of cutting. Volume Resistivity ASTM D257Ω/CM 3.0＊10；Hardness ASTM D2240 shore A＞80
