Characteristics and application of thermal gel

The thermal gel is a silicone resin as a base material, and the thermally conductive filler and bonding material are configured in a certain proportion. The paste-like gap filling material processed by a special process is mixed and solidified according to 1: 1 (mass ratio) It becomes a high-performance elastomer, which is molded with the shape of the structure, and has the best structural applicability and surface-applied characteristics of structural parts. This material has some of the advantages of both thermal pads and thermal grease, which makes up for the weaknesses of the two, and is especially suitable for space-constrained thermal conduction needs.

Characteristics:

1. Excellent thermal conductivity. Compared with thermal pads, thermally conductive gels are softer and have better surface affinity. They can be compressed to a very small thickness, the thinnest to 0.1mm, which significantly improves the heat transfer efficiency. At this time, the thermal resistance can reach 0.08 ° C · in2 / W-0.3 ° C · in2 / W, which can reach the performance of some silicone greases. It not only provides a high guaranteed heat dissipation coefficient for electronic products, but also provides electronic products (especially high heat dissipation) Product) Stability during use guarantees the product's performance and life;

2. It has superior electrical properties, aging resistance, cold and heat resistance (can work at -50 ~ 200 ℃ for a long time), electrical insulation performance, shock resistance, vibration absorption and stability, which increases the electronic products' use in the process of use. Safety factor;

3. Meet a variety of applications. It has no sensitivity to thickness, has good self-adaptability in the process of equipment assembly, and is compatible with the influence of related devices or structural parts on dimensional tolerances. It can provide good contact between the heating surface and the heat dissipation surface under low pressure or no pressure.

4. Advantages of continuous operation. The thermal gel is easy to operate and can be applied manually or mechanically. The commonly used continuous use method is mechanical dispensing, which can achieve fixed-point quantitative control, meet any working environment and working conditions, save labor and improve production efficiency.

Applications:
Mobile phone communication terminal, computer chip cooling, LED lamp chip cooling, high performance server, communication system equipment. Thermal gel can also be used in the processor of mobile phones. The thermal gel heat sink is used on the processor of Huawei mobile phones. This is better than the contact with a graphite heat dissipation film, and the heat conduction will be faster.
