The development of science and technology has brought a lot of convenience to people. Electronic products or electrical equipment have become indispensable in people's life and work. When the current passes through the resistance, heat will be generated. High temperature will damage the performance and service life of the equipment. Operation may cause the device to spontaneously ignite, so timely cooling is essential.
Thermally conductive material is a new type of material specially designed to solve the problem of heat conduction of equipment. It is widely used in all walks of life. my country's thermally conductive material industry started late, and currently occupies a large share of the domestic thermally conductive material market. It is an international brand with a high reputation in the world. , Such as Bergquist, Laird, Chomerics, ShinEtsu, Henkel, Denka and so on.
As we all know, the more sophisticated the equipment, the higher the environmental requirements for its operation. When people use various electronic products or electrical equipment, they often notice that the temperature will rise over time, and there will be lags during use. This is because the temperature is too high and affects the performance of the body. If the temperature is not lowered in time, the equipment may spontaneously ignite.
Excessive temperature has always been one of the factors affecting the performance and service life of electronic components. If the temperature is too high, the equipment may fail or even spontaneously ignite. In order to ensure the normal operation of the equipment, heat dissipation is essential.
Many people don’t know the ways of heat transmission. Simply put, they are heat conduction, heat convection, and heat radiation. The molecular arrangement in the air is relatively scattered, and the heat transfer speed is lower than that between solids, so some people will say Air is a poor conductor of heat. It is well known that heat is generated when current passes through electrical components. This is a common phenomenon. As long as electrical equipment is used, it will generate heat. Heat is not easy to circulate in the space, and it is easy to cause heat to accumulate, which makes local temperatures too high. As a result, the performance and service life of electrical components are lost, and in serious cases, it may cause spontaneous combustion of machinery and equipment.
With the development of science and technology, people are pursuing a higher and faster experience, and various electronic products and machines have higher performance requirements. The higher the performance, the higher the power consumption of the electrical component, which also means The higher the heat it emits. It is well known that high temperature is one of the factors that affect the performance and service life of electronic components. When operating at high temperatures for a long time, electronic components may fail, and the aging rate of materials at high temperatures will accelerate. Failure to solve the heat dissipation problem in time may result in machinery and equipment. Spontaneous combustion.
For a period of time, I have frequently received new and old customers about the thermal conductivity of thermally conductive silicone sheets. After understanding, I know that the product upgrade is fast and its performance requirements are getting higher and higher, so it is necessary to improve the performance of core components. , And the power of the equipment increases, the heat generated by it will increase, and the demand for heat dissipation will also increase.
Thermal conductive material is a new type of material that people often use to solve the problem of heat conduction of equipment. It is mainly used to fill the gap between the heat source and the radiator, eliminate the air in the gap, reduce the contact thermal resistance, and improve the heat conduction efficiency, thereby improving the overall equipment heat radiation.
All kinds of household electrical appliances and industrial machinery and equipment flood people’s lives and work. They bring convenience to people’s lives, but also have hidden dangers. Any electrical appliance will generate heat when it is in operation, because in reality there will be losses when electrical energy is converted into other energy. , Heat will be generated when the current passes through the resistor, so it is necessary to dissipate heat on the device. The heat in the electrical equipment is not easy to circulate, and the heat cannot be quickly dissipated to the outside after the heat is generated, which causes the temperature to rise. Therefore, a radiator is generally used. The radiator is installed above the heat source, and the heat is removed through the contact between the two The surface of the heat source is guided into the radiator, thereby reducing the temperature of the heat source.
In the recent communication with customers, I learned that the frequency of new product development by end customers is getting higher and higher, and the demand for heat dissipation is also higher and higher. In the past, relatively standard thermal conductivity materials can no longer meet its requirements, and they need to use better thermal conductivity. Of thermally conductive materials. The development of science and technology means that today's seemingly advanced technology may be surpassed in a short time. If it does not keep up with the pace of development in time, it may derail the world. Therefore, the development of thermal conductive materials also needs to keep up with the development of science and technology.
The development of the modern chemical industry is inseparable from the existence of electricity. It is necessary to use electricity to drive the operation of machines from large factories to small individual workshops. If you use various electrical equipment, it is naturally inseparable from the heat generation. And this This phenomenon cannot be avoided. Electrical equipment generates heat when it is running, because energy loss will occur during energy conversion, and heat will be generated when current passes through the resistor. Heat in the space inside the equipment is not easy to circulate, so it is easy to cause local temperature rise, so that electronic components will be affected by excessive temperature. Performance and service life.
Most people have experience in assembling a computer. When installing a computer CPU, you need to lightly apply a layer of silicone grease on the CPU in advance, and then install the cooling fan directly. If silicone grease is not applied, the temperature of the CPU during use It is still above the safe range, so silicone grease needs to be applied between the cooling fan and the CPU. Although the surface of the CPU and the cooling fan contact sheet are smooth and flat, there is a gap between the two bonding, and the heat transfer will be hindered, so that the heat cannot be effectively dissipated to the outside. The function of the thermal grease is to pass Fill the gap between the two and fill the gap with air, thereby reducing contact thermal resistance and improving thermal conductivity
With the development of science and technology, discrete graphics cards that used to be regarded as high-end accessories have now become popular in most computers, especially personal assembled computers. The performance of discrete graphics cards determines the computer's graphics processing capabilities. Currently sold and developed on the market 3A masterpieces and some image and video rendering require high-performance discrete graphics cards. In electrical equipment, the higher the performance of the equipment, the higher the heat generated, and the higher the heat dissipation configuration required. A large amount of heat will be generated when the computer is running. People often say that the computer burns mainly to describe a certain computer. Components burned due to excessive temperature, and graphics cards, CPUs, motherboards, hard drives, etc. are all key areas.
People often ignore their common problems when using various electrical equipment: fever, such as large servers, security monitoring equipment, assembly line production robots, logistics robots, etc. often need to work 24 hours a day. If the heat dissipation is not done well, It may cause electrical equipment to malfunction or even burn. Electrical equipment will generate a lot of heat when used, because when current passes through the resistor, it will generate heat. The greater the power of the electrical equipment, the more heat it generates. The internal space of the equipment is not easy to circulate heat, and the heat is easy to accumulate, making the local temperature too high. , And high temperature will cause the failure of electronic components, and the high temperature will accelerate the aging rate of the material, so it is necessary to dissipate heat in time.
The heat conduction problem of equipment is the most common phenomenon, such as heat generation of various consumer electronic products, household appliances, industrial machinery, etc. When current passes through the resistor, heat will be generated. Therefore, the operation of electrical equipment must generate heat. of. Temperature is one of the key factors that affect the performance and service life of the equipment, and high temperature will cause the temperature-sensitive electronic components to fail. At high temperatures, the material aging of the equipment will accelerate, which may cause fires in severe cases. In order to ensure the operation of the equipment, a heat dissipation system is necessary.
