Comprehensive understanding and market prospect analysis of heat-conducting graphite sheet products

Graphite heat dissipation filmIt is a new type of thermal conductivity and heat dissipation material with a unique grain orientation that conducts heat uniformly in two directions. The layered structure can adapt well to any surface, shielding heat sources and components while improving the performance of electronic products. Graphite heat dissipation film is not uncommon. Many years ago, manufacturers installed a thin film of thermal conductivity and heat dissipation on mobile phones, tablets, and other devices to reduce the temperature of the phones. But bringing it out to talk about Xiaomi Technology is the first time. The reason behind this is that the heat dissipation effect of the vast majority of heat dissipation films is not significant.

So, what is graphite heat dissipation film? Is there any difference or difference? Is the heat dissipation film used in Xiaomi phones effective? Next, Advanced Institute will unveil the secret of this heat dissipation film for everyone!

Graphite heat dissipation film is a thin film that conducts heat and dissipates heat. Graphite heat dissipation film is a new type of thermal conductive material with a unique grain orientation that conducts heat uniformly in two directions. Its layered structure can adapt well to any surface, shielding heat sources and components while improving the performance of electronic products. It is widely used in lightweight electronic products such as smartphones and tablets. The main categories of graphite heat dissipation film are:

Artificial graphite/carbon nanotube heat dissipation filmQuick heat dissipation, with little difference in heat dissipation effect. High price and easy to shape.

Natural graphite heat dissipation film: It is cheap, but it cannot be made very thin and has poor heat dissipation effect, making it difficult to form.

Graphene heat dissipation film: the best effect, but the price is too expensive, often over a thousand yuan; Low output.

1. Excellent thermal conductivity: thermal conductivity up to 600-1200w/(m-k) (equivalent to 2 to 4 times that of copper and 3 to 6 times that of aluminum), thermal resistance 40% lower than aluminum and 20% lower than copper;

2. Light specific gravity: 1.0-1.9g/cm3 (density equivalent to 1/4 to 1/10 of copper and 1/1.3 to 1/3 of aluminum);

3. Low thermal resistance, soft and easy to cut (can be repeatedly bent);

4. Ultra thin: thickness (0.025-0.1mm);

5. The surface can be combined with other materials such as metal, plastic, adhesive, etc. to meet more design functions and needs.
