Thermal Grease is a heat-conducting medium containing silicon-based materials, usually composed of silicone oil, thermal conductive fillers (such as aluminum oxide, silicon nitride) and other additives. Its main function is to fill the tiny gaps between the heat sink and the electronic components to enhance the heat conduction effect.
Ingredients
Matrix: usually silicone oil or organic silicon compound.
Thermal conductive fillers: used to improve thermal conductivity, common ones are aluminum oxide, silicon nitride, aluminum nitride, etc.
Additives: used to improve performance, such as antioxidants, stabilizers, etc.
Applications
Heat dissipation of electronic equipment
In electronic equipment such as computers, mobile phones, graphics cards, etc., Thermal Grease is used between the heat sink and the CPU and GPU to help effectively transfer the generated heat to the heat sink to avoid overheating.
LED lighting
In LED lamps, Thermal Grease is used to improve the heat conduction between the LED chip and the heat sink and extend the service life of the lamp.
Power electronics
In power electronic equipment, Thermal Grease helps transfer the heat generated by power semiconductor devices to the heat sink, improving the reliability and efficiency of the equipment.
Automotive electronics
In automotive electronic control units (ECUs), sensors and other components, Thermal Grease is used to improve heat dissipation and ensure stable operation of electronic components in high temperature environments.
Industrial equipment
In various industrial equipment, it is used to improve the thermal management efficiency of equipment and prevent failures caused by overheating.
Precautions for use
Apply evenly
Make sure the grease is applied evenly and in a thin layer to avoid bubbles or uneven heat conduction.
Clean surface
Before applying Thermal Grease, make sure the surface is clean and free of oil and dust to improve thermal conductivity and adhesion.
Avoid excessive use of excessive grease may cause poor heat conduction, so use it according to the recommended amount.
Regular inspection
Thermal Grease may dry up or fail over time and temperature changes. Regular inspection and replacement are key to ensuring stable operation of the equipment.
