What is thermal paste?

High temperature is a phenomenon that people cannot ignore. If people work under high temperature for a long time, it is easy to cause serious adverse reactions in the body. In severe cases, it can cause shock or even death. Even machines and equipment that appear to be sturdy by humans are not suitable.

High temperature can cause damage and aging of internal parts of machine equipment, which has a negative impact on its performance and service life. In severe cases, it can cause machine equipment to crash or even catch fire. During the operation of machine equipment, it will generate heat, such as when the motor is used, when the phone is used, the back is heated, and when the computer is used, the motherboard is heated, etc. This is mainly because the computer converts heat into energy, which is accompanied by energy loss. When the current passes through a resistor, heat is generated, which is also one of the main reasons for machine equipment heating during operation.

The internal space of machine equipment is built through calculation, so the internal space will be relatively narrow. The heat emitted by the heat source is not easy to conduct to the outside, so it is easy to accumulate, which makes the machine equipment heat up without proper heat dissipation measures. In order to effectively reduce the temperature of the machine equipment and ensure its stable operation for a long time, people will install a radiator above the heat source, intentionally guiding the heat into the radiator to lower the temperature.

However, in reality, the heat dissipation effect does not meet expectations because there are gaps between the heat sink and the heat source, where there is a large amount of air. Air is a poor conductor of heat, and the rate of heat transfer through air is reduced, resulting in the unsatisfactory heat dissipation effect. The solution to this problem is relatively simple. By filling thermal conductive materials between the heat source and heat sink, the air between the gaps is eliminated, allowing the heat sink and heat source to come into close contact, thereby improving thermal conductivity.

There are many kinds of thermal conductive materials on the market, such as thermal conductive silicon film, silicon free thermal conductive sheet, thermal conductive phase change sheet, thermal conductive gel, thermal conductive silicon tape, carbon fiber thermal conductive gasket and thermal paste. Thermal paste is one of the widely used thermal conductive insulation materials, and its practicality and high cost performance are loved by people. So what is thermal paste?

Heat dissipation paste, also known as thermal  paste, is a popular thermal conductivity material in the field of thermal conductivity materials today. It is a semi fluid paste like composite based on silicone resin, with high thermal conductivity, low thermal resistance, and excellent lubrication performance. It can form an extremely thin surface layer at rough interfaces, which is easy for secondary heavy industry. It is commonly used to fill the gaps between power consuming electronic components and heat sinks to improve the thermal conductivity efficiency of heat sinks, and is widely applicable in the current industrial process field.
