Heat production are common of all electronic equipment, electronic equipment operation process, the current flow to the electrical components, because the relationship between the resistance to generate heat, this is unavoidable, air is a poor conductor of heat, high space utilization, inside the equipment to heat circulation were in equipment, easy to make the heat accumulation and makes the temperature rise.
High temperature has been one of the factors affecting the operation of electronic equipment, long time work under the high temperature easy to damage the electrical components, make its failure and even serious spontaneous combustion equipment, so the heat dissipation is an integral part of all electronic devices have in common, electronic equipment operation is unable to avoid generate heat, because when an electric current passes through electrical components will generate heat, as long as the control of the heat source temperature, To ensure the operation of the equipment.
Thermal conductive silica gel sheet, as a thermal conductive joint filling material specially used to solve the problem of heat conduction of equipment, is used in all walks of life in the demand for heat dissipation of equipment. When electronic equipment runs, it will inevitably produce heat. High temperature will affect the performance and service life of the equipment, so heat dissipation is a common feature of electronic equipment.
When people deal with the heat conduction problem of equipment, they tend to pay too much attention to the thermal conductivity of thermally conductive gap-filling materials, and often ignore the thermal resistance value of thermally conductive gap-filling materials. In fact, the thermal resistance of thermally conductive gap-filling materials is related to the surface-to-surface contact. Thermal resistance also needs attention.
The information age is the theme of the current society. People's lives and work are inseparable from the support of data and networks. As one of the representative industries of the information age, the information/data communication industry plays a very important role in the construction of a modern society. Because of their existence, people can connect with the world through terminals such as mobile phones and computers.
I believe most people will be exposed to the heat generated by electrical appliances. The higher the power of the electrical appliances, the higher the heat generated. Working at high temperatures for a long time will cause irreversible damage to electrical parts, and it is easy to cause spontaneous combustion. The phenomenon occurs, so electrical safety has always been a concern of people.
People often come into contact with some consumer electronic products in their life and work. Consumer electronic products contain electronic devices and equipment specially designed to meet people's daily needs, such as communication equipment, household appliances, office supplies and so on.
When people deal with the heat conduction problem of equipment, they often think of installing a heat dissipation module on the heat source components in the equipment to actively guide heat transfer and improve the temperature in the heat source. However, after installing the heat dissipation module, it is found that the actual working efficiency of the heat dissipation module does not meet expectations. why is it like this?
Many people know that heat can be effectively transferred from a high temperature to a low temperature surface by contacting each other, but there is a gap between the surfaces, because the two solid surfaces that are in contact with each other actually contact some discrete areas, The other non-contact interfaces are filled with air, which causes the heat to be subjected to its additional resistance when passing through, which is the resolution of the contact thermal resistance.
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.
