The mobile phone may become hot after a long time of use. If it is not stopped or placed in a cool and ventilated place to dissipate heat, the mobile phone may crash. Heat is unavoidable during the use of electrical equipment. If it is ensured that the heat can be effectively transferred to the outside when the equipment is in use , which becomes the place to be concerned.
When people solve the problem of heat conduction in equipment, they often think of thermally conductive materials for the first time, because there is a gap in the contact interface between the heat source in the equipment and the radiator, and the heat is transferred between the two due to the resistance of the air, which causes the speed to drop, so that the heat dissipation effect reaches the equipment. Reasonable operation under the requirements.
Different materials have different characteristics of the products. As a material specially used for heat conduction problems in equipment - thermal interface material, its function and effect have been recognized by people, and it has been extended to more applications. Thermal interface materials are different from For other filling materials, its main function is to reduce the contact thermal resistance between the contact interfaces and improve the thermal conduction effect.
The phenomenon of equipment heating often occurs in people's lives, such as mobile phone heating, computer heating, motor heating, electric vehicle heating, etc. When the current passes through the resistance, heat will be generated, so the equipment heating is unavoidable, but the high temperature will affect the equipment. The operation of the equipment may even cause spontaneous combustion of the equipment in severe cases.
When the current passes through the electric resistance, heat is generated, which is widely present in all aspects of society. Although people have developed electric heating equipment such as electric heating rods, electric ovens, electric ovens, electric heaters, etc. according to this phenomenon, most of them Situation This is a loss of energy, energy cannot be completely converted into target energy, and high temperature is one of the factors affecting the operation and service life of electronic equipment.
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.
