September 16, 2011, Xiaomi cell phone in Beijing 798 held a conference. At the meeting, Lei Jun, CEO of Xiaomi Technology, said: As Xiaomi cell phone uses a dual-core 1.5G processor and a large screen, the heat dissipation problem is very critical. After the use of graphite cooling film, users will almost never experience the hot phone in the process of use. The term "graphite thermal film" is known to all.
Graphite thermal film is a new thermal conductive material with unique grain orientation, uniform thermal conductivity in both directions, lamellar structure that can be well adapted to any surface, shielding the heat source and components while improving the performance of consumer electronics products. The product dissipates heat uniformly while also providing thermal isolation in terms of thickness. The molecular structure of thermally conductive graphite flakes is shown below: Graphite Thermal Conductive Sheet Solutions The unique combination of thermal dissipation and insulation properties make thermally conductive graphite an outstanding material choice for thermal management solutions. Thermally conductive graphite sheet has an ultra-high thermal conductivity in the range of 150-1500 W/m-K in-plane.
GS Thermal Graphite sheet is a naturally occurring mineral with a single element of carbon (C) as its chemical composition. Thin film polymer compounds can be chemically high temperature and high pressure graphitized film, because carbon is a non-metallic element, but there are metal materials, electrical conductivity, thermal conductivity, but also has the same plasticity as organic plastics, and there are special thermal properties, chemical stability, lubrication, and can be coated on the surface of solids, and so on some of the good process performance, therefore, thermally conductive graphite in the electronics, communications, lighting, aviation and defense industry and many other fields. Aviation and defense industry and many other fields have been widely used.
Graphite thermal conductive materials provide the heat management industry with a comprehensive high performance unique solution. Thermally conductive graphite materials through a series of different thermal management solution applications to the increasingly wide range of needs of the industrial heat dissipation field to bring new technology solutions, thermally conductive graphite material products provide the electronics industry heat management of innovative new technologies. Thermally conductive graphite by reducing the weight of the device in the case of providing better thermal conductivity, B&C thermal graphite thermal solution is a new application of thermal design program. Thermal graphite effectively solves the thermal design problems of electronic devices, widely used in PDP, LCD TV, Notebook PC, UMPC, Flat Panel Display, MPU, Projector, Power Supply, LED and other electronic products Graphite thermal material. Graphite heat dissipation material has been widely used in communication industry, medical equipment, Sony/DELL/Samsung notebooks, ZTE cell phones, Samsung PDP, PC memory sticks, LED substrates and other heat dissipation.
GS graphite thermal film features advantages:
1. Excellent thermal conductivity: thermal conductivity of up to 600-1200 w/(m-k) (equivalent to 2 to 4 times the copper, 3 to 6 times the aluminum), thermal resistance than the aluminum is 40% lower than the copper is 20% lower
2. Specific gravity is light: 1.0-1.9 g/cm3 (density of copper 1/4-1/10, aluminum 1/1.2%, aluminum 1/1.3%, aluminum 1/1.3%, aluminum 1/1.3%, aluminum 1/1.3%, aluminum 1/1.3%. 10, aluminum 1/1.3 to 1/3)
3. Low thermal resistance, soft and easy to cut (can be bent repeatedly)
4. Ultra-thinness: thickness (0.025-0.1mm)
5. Surface can be combined with other materials such as metal, plastic, sticker, etc. to meet the needs of more design functions and requirements
