In the heat dissipation management of modern electronic equipment, thermally conductive silicone sheets, as an important thermal interface material, play a key role. It is widely used in heat conduction processing of various equipment due to its excellent thermal conductivity, low thermal resistance and soft elasticity. However, in the process of using thermally conductive silicone sheets, there is a problem that cannot be ignored-the precipitation of silicone oil, which may have an adverse effect on some specific equipment.
As a new product in the heat dissipation adhesive market, high thermal conductivity silicone gaskets are thermal conductive media mixed with silica gel base materials and auxiliary materials such as metal oxides. They are specially used to reduce the contact thermal resistance between heat sources and heat dissipation devices. This material is designed to efficiently transfer heat between heating parts and heat dissipating parts. It not only improves heat dissipation efficiency, but is also widely favored for its environmentally friendly and economical properties.
In today's digital era, LED displays have become an important tool in many fields such as advertising and information display. Especially in outdoor environments, LED displays are popular for their distinctive visual effects. However, whether it is an outdoor or indoor LED display, it will generate a lot of heat during use. If this heat cannot be effectively discharged, it will have a serious impact on the reliability and life of the display.
In the operation of modern electrical equipment, an effective heat dissipation system is a key factor in maintaining equipment stability and extending its service life. Since electrical equipment inevitably generates heat during long-term operation, if not controlled, the high-temperature environment may cause irreversible damage to the equipment. Therefore, an efficient cooling system is not only necessary, but also critical.
the thermal gel can also be used in the mobile phone processor, Huawei's mobile phone processor will be used similar to the silicone grease thermal conductivity of the heat, this is better than the only sticky graphite heat film contact effect better , Heat conduction will be more rapid.
In the ordinary life and work, the Thermal Silicone Adhesive film has been gradually widely used in electronic and electrical products control board, motor, external pad and foot pad, electronic appliances, automotive machinery, computer host, laptop, DVD, VCD and any Need to fill and heat the module material.
Thermal Silicone Adhesive is based on silica gel as the substrate, add metal oxide and other auxiliary materials, through a special process of synthesis of a thermal medium material, is designed for the use of heat transfer design of the gap design, to fill the gap, to complete the heat And heat dissipation between the parts, but also play a role in insulation, shock absorption, sealing, etc., to meet the equipment miniaturization and ultra-thin design requirements, is very technical and usability, and the thickness of a wide range of applications, An excellent thermal filler.
Thermal Silicone Adhesive with silica gel as the carrier, by adding thermal conductive material and to alkali-free glass fiber as the support, rolling by the thin material rolling machine can be filled with a good heat sink and heat sink between the gap, Uneven surface of the air, can form a good heat flow channel; and itself has a good thermal conductivity, is widely used in electrical and electronic products, thermal conductivity material.
Beauty paper tape has good adhesion, good adhesion, good temperature resistance, excellent anti-solvent penetration function, good stability.
Generally speaking, the thinner the thermal conductive silicone pad, the better, so that it can be more useful for conducting heat. However, there is also a limit, it is not possible to reach the thickness of thermal insulating materials or thermal conductive silicone screen printing.
Often we see that because you can't tell the difference between thermal conductive silicone grease and smooth silicone grease, you don't know how to use it after buying silicone grease. Maybe Zhang Guanli Dai used the wrong silicone grease and made some ironic things. As a hardware enthusiast who has been burning for several years, I have some knowledge of silicone grease. Let me give you a brief introduction to this small "silicone grease".
Mobile phones are electronic products with a high penetration rate in society. Basically, people have their own mobile phones when they go to college, and people who work in society have multiple mobile phones. As the pace of life continues to accelerate, mobile phones do not Electricity has become one of the problems that worry people, and fast charging source adapters that can realize fast charging have become people's pursuit. Major manufacturers have also realized this problem and invested in it. Under normal circumstances, the power adapter used by the mobile phone is a standard type. The charging time of the mobile phone is determined according to the battery capacity of the mobile phone, and the fast charging source adapter can greatly reduce the charging time, which can reduce the original two hours to half an hour , So that people can spend the least time to get the best results.
Under normal circumstances, there is no gap between the heat source and the radiator when observed with the naked eye, but in fact, there are some uneven pits on the surface of the two. When the two are attached, there will be some gaps. The air in the gap hinders the heat. Because of the transfer factor, direct bonding will lead to heat transfer efficiency. The heat transfer material needs to be filled here so that the gap between the two can be filled and the gap between the interface can be eliminated, so that the heat source and the radiator can be in close contact and improve the heat transfer efficiency.
Many people have a question when assembling a computer. Why do you need to apply a layer of grease to the CPU when installing the cooling fan? There is a slight gap, and the thermal conductivity of solid is better than that of gas, so theoretically the heat dissipation effect will be quite good, but in fact it is not. Why is it so? The surface of the heat sink and the CPU looks like a smooth and flat surface, but there are actually some irregular planes, so when the two are attached, there will be many pits. There are a lot of air in the pits. When the heat comes from the surface of the heat source (CPU) When transferred to the heat sink, 100% seamless transfer cannot be achieved, but some heat needs to pass through the air in the pit before being transferred to the heat sink, so the heat dissipation effect is not ideal.
When it comes to computers, people first think of thin and light displays, simple and efficient chassis, and then the world's first general-purpose computer has the size of two rooms. The computer has changed from the size of two rooms to the size of a suitcase. It can be said that the future development direction is the trend of light and thin, multi-functional. In real life, people use mobile phones, tablets, smart watches and other electronic products that are multi-functional, thin and lightweight. As time goes by, the frequency of mobile phones is also accelerated. It may have been two years before a new generation was released. Mobile phones, which may be released in half a year now, and the new generation of mobile phones are thinner, more versatile, and more durable than the previous generation, which leads to further compression of their internal space utilization. When electronic products are in use, heat will be dissipated, because the energy conversion cannot reach 100%, there will be a part of energy loss, and a large part of this part of energy is lost in the form of heat. Other analysis is When current flows through the resistor, heat is generated. This phenomenon is normal, but serious heat will cause damage to the components, so heat dissipation should be performed in time.
