In summer, in addition to feeling the high temperature brought by the weather, the high temperature generated by various equipment around life and work is also directly contacted by people. The long-term operation of equipment at high temperature is a kind of Irreversible wear and tear may seriously lead to equipment failure or even spontaneous combustion.
Recently, many customers have contacted our company through the Internet to inquire about the related issues of high thermal conductivity gap filling materials, because they also know the relevant situation during the exchange process. At present, in the hot summer, in addition to the extremely hot weather, all kinds of machines The performance of the equipment is damaged due to high temperature, and even spontaneous combustion occurs.
With the continuous introduction of electrical equipment, people's lives have become more convenient and efficient. High performance and miniaturization are the trends of its development. Faster speed and stronger functions mean that the power of the equipment will also increase with the increase in power. , and heat generation is the commonality of electrical equipment, so the demand for heat dissipation is also enhanced.
Many people may not know that in reality, two solid surfaces that are in contact with each other are actually only some discrete areas in actual contact, and the other uncontacted interfaces are filled with air. It is well known that air is a poor conductor of heat. The additional resistance is called contact thermal resistance. The greater the contact thermal resistance between the two, the higher the resistance when the heat passes through, and the heat conduction efficiency is reduced.
Heat dissipation systems are widely found in all kinds of electrical equipment. Heat generation is a common feature of electrical equipment. Working at high temperatures for a long time will cause irreversible damage to the equipment. Therefore, the heat dissipation system is necessary and very important.
For an electrical equipment, the design and construction of the heat dissipation coefficient is very important. Heat generation is common to all electrical equipment, because heat will be generated when the current passes through the resistance. Since it cannot be avoided, it should be improved. The construction enables the device to operate at a controlled temperature.
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.
