Mobile phone common cooling materials are:
1, artificial graphite sheet
Thickness is thin, up to 0.017mm; high thermal conductivity, thermal conductivity in the 1500-2000w/m.k; thermal conductivity effect is very good, the price is slightly higher.
Artificial graphite sheet common application industries: cell phones and other electronic products, communication industry, notebooks, medical equipment, LED substrates and other thermal cooling.
2, metal backsheet (film)
The thermal conductivity area is large, the metal thermal conductivity is high, can quickly dissipate heat; wide range of uses, good texture, good heat dissipation; but the strength is low, easy to break.
Metal backsheet (film) materials are commonly used in the following industries: cell phones and other electronic products, medical equipment, industrial production and other cooling.
3, thermally conductive gel
Soft and has a good affinity; no obvious hardness, the equipment does not produce internal seating force; adhesion is weak, can not be used to fix the heat sink.
Thermal conductive gel common application industries: cell phones and other electronic products, electrical equipment, heat dissipation facilities, such as cooling.
4, phase change cooling materials
Solid-solid phase change or solid-liquid phase change materials, can conduct heat can also absorb pastoral heat; can meet the thinner body, the processor part of the heat consumption, heat dissipation and cooling effect is good; but at present, the phase change material cost is higher; common force Wang new materials heat absorption and cooling phase change materials.
Cooling phase change materials are commonly used in the following industries: 5G communication equipment, cell phones and other electronic products, electrical equipment, and other heat dissipation and cooling.
Materials need to be good quality effect is more obvious, choose a large company, such as the force king of new materials, small companies are prone to uneven quality. At present, with the development of science and technology and the maturity of the cooling program, some of the original cooling materials used in the PC and cooling technology is also used in the cell phone, such as copper cooling, water cooling.
