The Invention of Nanocarbon Heat Dissipation and Heating Technologies

 
TAOYUAN, Taiwan - Feb. 25, 2024 - PRLog -- In the process of making graphene, a large amount of defective products are produced. Dr. Hung-Chih Lu felt that it was a pity to discard them and wanted to make use of them. Through his experiments, he found that these defective products did not have good electrical and thermal conductivity, but their thermal radiation was still excellent.

The first product he applied to was LED, which was a big bottleneck for heat dissipation at that time. He achieved very good results. The thermal radiation power was proportional to the fourth power of the temperature. The higher the temperature, the better the thermal radiation. Therefore, he applied for and obtained the US patent US9170015 in 2013. Although the embodiment of this patent was LED, the scope of the patent was not limited to this. Dr. Hung-Chih Lu also invented the application of nanocarbon heating technology.

The best implementation of nanocarbon heat dissipation technology is shown in Figure 1. This is a passive liquid-cooled heat sink using nanocarbon heat dissipation technology. The left side of Figure 1 is the overall appearance diagram, and the right side is the cross-sectional diagram, which is used to explain the internal structure.

A heat-dissipation plate at the bottom is connected to a heat source. It transfers the heat to a liquid inside it. The liquid has a special shape that helps it touch more of the metal and cool it down faster. The liquid then moves to another heat-dissipation plate at the top and gives it the heat. The top plate has a honeycomb design that looks nice and feels good. It also has a thin layer of carbon that radiates the heat away.

In order to compare the thermal radiation capabilities of these nanocarbon families: such as graphene, nanocarbon spheres, nanocarbon tubes and diamond-like carbon, pure aluminum plates are plated with these carbon family materials respectively, and Dr. Hung-Chih Lu's nanocarbon heat dissipation material with a special formula mixture is added. The test results of thermal radiation heat dissipation ability are shown in Figure 2. After thermal equilibrium, pure aluminum without coating is about 96 degrees, nanocarbon family, the difference is very small, the temperature is about 86 degrees, Dr. Hung-Chih Lu's nanocarbon mixture is the lowest, the temperature is about 81 degrees, which can prove that in actual use, nanocarbon materials can provide excellent thermal radiation heat dissipation.
