Applications

The demand for high-performance heat spreaders becomes more urgent as the tablets and Ultrabooks become thinner and lighter. The thermal processor needs cooling, and the shell’s hot spot must be eliminated. All these must be done by thin and efficient heat-transfer products. With the widest range of ultra-high performance pyrolytic graphite sheets, we have the right thermal solutions to meet the performance needs of the industry.

Test situation description:
1. Test room temperature - 25.6℃, no convection wind, 2 tablets with the same configuration of the same model.
2. Open wireless connection; download the network game "protect corn".
3. Adjust the brightness, contrast, volume to maximum.
4. After installations, start games simultaneously on the two machines, place the tablet computers on the scaffold, two engineers operate the game.
5. Every 10 minutes, the temperature change of the core position of the main board is measured with a thermal imager.
6. The data are measured 3 times and data entry is completed.

Conclusion: the high thermal conductivity of graphite heat dissipation film is far superior to the traditional heat conduction materials.
From the above test process and data, we found the temperature difference is close to 10 degrees between using and not using the graphite heat dissipation film.
This feeling is very important for the customers.
