What is the Heat Dissipation Effect of Graphite Powder?

As a Graphite Electrodes Solutions Supplier, share with you. Graphite has excellent thermal conductivity, 700-1300 watts/(MK) thermal conductivity (corresponding to 2 to 3 times copper, thermal conductivity of metal materials such as copper and aluminum far exceed), the weight is more than copper and aluminum Light, with a density of 0.85-1.9 g/cm3 (corresponding to 1/4 to the density of copper, 1/10 of the density of aluminum, 1/1.3 to 1/3), and has a better processing natural graphite material than aluminum It is made of copper material with high thermal, chemical and physical stability and high conductivity. Excellent heat dissipation is the material used for radiators.

Graphite Electrodes

Graphite rods are often used as electric heating elements in high-temperature vacuum furnaces. The maximum operating temperature can reach 3000°C. It is easy to oxidize at high temperatures. Except for vacuum, it can only be used in neutral or reducing atmospheres. Its thermal expansion coefficient is small, thermal conductivity is large, resistivity is (8~13)×10-6 Ω·m, processability is better than SiC, MoSi2 rod, high temperature resistance, extreme cold and extreme heat resistance, good price Cheaper. Graphite block is a kind of artificial graphite, and artificial graphite is made by artificial heating of coke products. Generally, if it is purified to make high-purity or carbon fiber, the added value is high.

Graphite electrodes are mainly made of petroleum coke and needle coke as raw materials, coal tar pitch as a binder, and are made by calcination, batching, kneading, pressing, roasting, graphitization, and machining. It releases electric energy in the form of electric arc in an electric arc furnace The conductors that heat and melt the charge can be classified into ordinary power, high power and ultra-high power according to their quality indicators. Graphite electrodes mainly include four types of ordinary power graphite electrodes, anti-oxidation coating graphite electrodes, high-power graphite electrodes and ultra-high-power graphite electrodes. The thermal conductivity of the famous Chinese graphite radiator is 700-1300 watts/(Mk), the thermal conductivity of 0.85-1.9 g/cm3, the density of the thermal conductivity characteristics, the use of these natural materials of graphite and processing into various shapes according to the company’s product market requirements The radiator has excellent chemical and physical system stability, excellent electrical conductivity, directional heat dissipation efficiency, high heat dissipation efficiency, and can effectively shield electromagnetic wave radiation and absorb nuclear radiation. It is widely studied and applied in China Chemical Industry, Metallurgy, aviation, electronics, nuclear physics and other fields.
