What is a liquid metal thermal paste?
Liquid metal thermal paste is a paste-like material with metallic characteristics.
It has the following characteristics:
1. High thermal conductivity
2. Good adhesion
3. High temperature resistance
4. Does not flow at high temperatures
6. Does not oxidize
7. Does not cure at room temperature
9. Non-flammable and explosive
10. Non-toxic environmental protection
Application fields of liquid metal thermal paste.
Liquid metal thermal pastes can be used in magical aerospace and Computer configuration, and much more. This is a novel in recent years, and its thermal conductivity is far superior to traditional silicone oil-based silicone grease.
The method of use is to first clean the surface of the object, take out a small amount of liquid metal thermal paste, and apply it evenly on the surface.
It is also a pure metal paste-like thermal interface material, which has super high thermal conductivity and stability, can break through the traditional thermal interface materials, and has excellent thermal conductivity. Widely used for heat dissipation of electronic equipment in high temperature and high density heat flow occasions.
How often to replace the liquid metal thermal paste ?
After testing, the performance of the liquid metal thermal paste used on the CPU for more than 2 years has not deteriorated
It can be seen that the liquid metal thermal paste has a long service life.
Liquid metal is
conductive, novices need to do a good job to insulation, and don’t put liquid
metal with aluminum and aluminum alloy
Liquid metal thermal paste and thermally conductive silicone grease
Silicone grease filling effect
For safety considerations, the conductivity of silicone grease must be very weak. Therefore, some silver and aluminum will be added on the basis of aluminium oxide to improve the thermal conductivity. Due to the smallest particles still can’t fill the gap completely, the effect of silicone grease is very limited.
Advantages of liquid metals
Even if the traditional silicone grease doesn’t care about the conductivity, full use of metal powder is useless. The cost of moving from micron to nanometre will increase exponentially, but the performance will be not very strong.
Metals are directly composed of atoms, and the atoms are connected by metal bonds. Since the outer layer of the gallium atom has only three electrons, the force of constraining between the atoms is very weak, so the gallium-based alloy can be in a liquid state at normal temperature.
Liquid metal filling effect
The performance of liquid metal is modified by a special process. The metal thermalpaste made by adding nanometre metal particles is a 100% thick metal thermal grease with a thermal conductivity that more than 20 W / m · K, it’s very adhesive and heat resisting. It will not flow, evaporate, oxidize or dry out in high temperature environments. It is an ideal thermally conductive material to replace silicone grease. It can also be used for IGBT and large LED cooling, power battery cooling, CPU / GPU cooling, and can maintain high thermal conductivity and safety for a long time.
Metal thermal paste is a non-toxic product that complies with EU RoHS standards. It can be directly applied between the heat source and the heat sink, which can completely fill the gap and take advantage of the high thermal conductivity of the metal. The applied thickness can be between 0.01 mm and 0.2 mm. At the same time, the liquid metal does not react with copper and stainless steel, so that the safety and service life of the contact device can be achieved.

At present, the liquid metal thermal conductive agent is most widely used in the CPU cover opening, and its purpose is to enhance the performance of the thermal conductive medium between the silicon chip and the top cover. In fact, you can use it on the top cover and graphics card as long as you handle it carefully. In size-constrained devices such as laptops and graphics docks, liquid gold can be used instead of thermal grease to increase thermal conductivity. When liquid metal is used for servers that seek stability and heat dissipation, it can reduce the temperature and reduce the number of rotations of the cooling fan, which can reduce the temperature and save power.
