Information

Start with thermal design and thermal management solutions

The Nature of Heat：The phenomenon is essentially a manifestation of the irregular motion of a large number of molecules within an object (the current mainstream perception in science)

Thermodynamics：Heat is the rate at which the extra-nuclear electrons operate, and the movement of electrons is closely related to heat (high … … high extra-nuclear electron rate;low extra-nuclear electron rate).

Material classification

Product Description

The nano-thermal cooling material is a new generation of composite even heat conduction and heat dissipation material developed by taking the nano-treatment of copper/aluminum-platinum as the substrate and combining with the nano-thermal conductive material, thermal radiation even heat material, insulating low-acid thermal conductive adhesive, special treatment graphite and other materials, the cooling of the whole machine of this series of materials reaches 10~20 ℃, and the even heat dissipation performance is better than the artificial&natural graphite in the current market.

Product structure：

The above material structure layer thickness is not a fixed value, can be adjusted according to customer requirements, due to the different requirements of the thermal degradation of electronic products, you can adjust the material structure.

note：Due to the increased thickness of the metal material, the heat-melting ratio of the material increases, its surface temperature and the heat drop ratio of the bottom heat source will change significantly

Product Advantages：

1. Through the conduction heat dissipation + convection heat dissipation + radiation heat dissipation can quickly convert the point heat source into surface heat source, and through the radiation heat dissipation to achieve cooling. Effect.

2. Can reduce the temperature of electronic products, protect electronic components and extend the life of electronic products.

3. Exclusive research and development of heat radiation, low acid heat evenly, insulating low-acid thermal conductivity glue, will not corrode electronic components.

4. The material has excellent insulating properties.

5. After die-cutting, the edges are neat and dust free (single natural graphite film or synthetic graphite film with graphite on the edges after die-cutting). (dust, which will affect the electronic elements inside products such as mobile phones and tablet computers).

6. It is good for reworking the machine and can be used again (natural graphite film or synthetic graphite film will be damaged during reworking and cannot be used again. (not conducive to return to service).

7. After die-cutting, it can be used directly, some products do not need to wrap (such as direct contact with electronic components circuit and line processing is recommended to wrap to avoid). (natural or artificial graphite would need to be hemmed and insulated, which would waste time and increase costs). (cost).

8. The most cost-effective advantage.

Test conclusion

Test data
	Test-1	Test-2	Test-2
Material Name	artificial graphite	TY-CNTp series	A Japanese brand
thickness	0.05MM	0.045MM	0.05MM
time	30min-60min	30min-60min	30min-60min
hot spot temperature	75.7	77.5	74.5
Heat sink material temperature	51.4	54.5	50.7
Enclosure testing	48.5	47.3	47.9

The TY-CNTp series had the highest point heat source during the test and the highest temperature in the heat sink material, reflecting the Excellent thermal conductivity of the material itself (the higher the temperature, the faster the temperature transfer); the temperature in the housing is the lowest. The reason is that the thermal energy is converted into infrared energy for heat dissipation through radiation heat dissipation, which reflects the heat dissipation of the product. Experiment proves, TYGS series of multi-level thermal conductivity, heat dissipation principle is better than similar products on the market today.
