The problem of mobile phone heating has become a trouble that people often encounter in daily life, and if it is serious, it may cause the mobile phone to ignite spontaneously, so the heat dissipation problem of the mobile phone is the focus of the engineers to solve. Mobile phone heating is unavoidable, because in reality, the energy conversion process is often accompanied by loss, especially the conversion of electrical energy into other target energy is heavier. The operation of mobile phones requires batteries to increase power, and heat will be generated when current passes through the resistor. , And the amount of heat is related to the power of the device, which is why the heat dissipation requirement of 5G mobile phones is much higher than that of 4G mobile phones.
Why can't the radiator directly contact the heat source to dissipate heat, but need to fill the medium between the two? When assembling a computer, people usually apply thermal paste on the surface of the CPU before installing the cooling fan above the CPU, and then install the cooling fan, because there are gaps between the radiator and the heat source, there are many holes and air in the gap, and the heat is The transmission process will be hindered, thereby reducing the heat dissipation effect.
When the machine and equipment are running, the heat is generated when the current passes through the resistance. The heat is not easy to circulate in the interior, which can easily lead to local temperature rise and affect the equipment. It is necessary to install a radiator above or near the heat source to guide the heat from the surface of the heat source to the outside, so as to reduce its temperature.
Thermal conductive material is a kind of new material to solve the problem of heat transfer equipment, machinery and equipment usage will fever is the common fault of the power devices, want to solve the problem of heating is impossible, because in reality is accompanied by a loss of energy conversion, this part of the loss of a large share of energy in the form of heat to the outside, if there is no in time will lead to the external heat, The machine equipment may cause performance damage or even crash due to high temperature.
The heat generated by electrical equipment during operation is mainly because heat is generated when current passes through the resistor. The heat does not flow easily inside the electrical or electronic product, so it is easy to increase the local temperature. It is necessary to install a radiator to guide the heat emitted by the heat source to the radiator , In order to reduce the temperature.
The heat conduction problem is one of the key solutions in the field of thermal management today. Electrical equipment or machinery will generate heat during operation. Because the external current passes through the resistor, it will generate heat. The internal space of the equipment is not easy to circulate heat, which will easily lead to an increase in temperature. The performance and service life of the equipment.
All kinds of electronic products and electrical equipment fill people’s lives and work. The convenience and efficiency of electrical equipment make people deeply dependent on them, just like the status of mobile phones in people’s hearts. In addition to mobile phones, like There are many machines driven by electric energy in large-scale machine tools, electroplating fields, pure electric vehicles, etc., and they also have inevitable problems.
The contact surface of the cooling fan is attached to the surface of the CPU. The excess heat of the CPU will be transferred to the radiator through the contact between the two. However, there is a gap between the contact surface of the radiator and the CPU, even though both are smooth and flat. It is necessary to use a thermal conductive material similar to thermal grease to fill the gap between the two to eliminate air, reduce the contact thermal resistance between the two, and improve thermal conductivity, so as to ensure that the CPU will not malfunction due to excessive temperature during operation.
The thermal gap filling material is a new type of material that solves the heat transfer problem of equipment or electronic products. With the development of science and technology, the development trend of miniaturization, high integration, light and thin dexterity makes the product’s heat dissipation requirements higher, and the general direct Contact heat dissipation can no longer meet its heat dissipation requirements, so the emergence of thermal gap filling materials provides a solution to its heat conduction problem. There are many kinds of thermal gap filling materials, such as silicone thermal film, silicone oil-free thermal pad, thermal gel, thermal conductive silicone cloth, thermal grease, thermal phase change film, carbon fiber thermal pad, etc. Most of the thermal gap filling materials It is made with silicone oil as raw material. Of course, some products that are sensitive to silicone oil or require high operating environment require the use of heat-conducting materials that do not contain silicone oil.
Many electrical equipment and electronic instruments have a prescribed voltage. When current passes through a resistor, heat is generated. The heat is not easy to circulate inside, resulting in an increase in temperature and affecting the equipment. High temperature will cause temperature-sensitive semiconductors, electrolytic capacitors, and processors. When electronic components fail, the aging speed of materials will be accelerated under high-temperature environments, so heat needs to be directed to the outside to reduce the temperature of the equipment.
The use of electrical equipment is a process of energy conversion, and the conversion of electrical energy into target energy is often accompanied by loss, and most of the lost energy will be dissipated in the form of heat. The greater the power, the greater the amount of heat it emits. The more, the higher the requirements for heat dissipation. Mounting the radiator above the radiator can effectively reduce the temperature of the heat source, but there is a problem: there is a gap between the radiator and the heat source.
High temperature will cause temperature-sensitive semiconductors, electrolytic capacitors, processors, and other electronic components to malfunction, material aging speeds up, internal parts are prone to fire due to high temperatures, so timely heat dissipation is required, and the heat source of machinery and equipment is not the whole, but Similar to power consumption electronic components, it is necessary to install a radiator or heat sink above or near it to guide the heat to the outside, thereby reducing the temperature.
Contact between the radiator and the heat source surface is a common way to dissipate heat, but there is a gap between the radiator and the heat source surface. When the heat transfer from the heat source surface to the radiator is hindered, the heat dissipation effect is reduced, so thermally conductive gap fillers are required. There are many types of thermally conductive jointing materials, such as thermally conductive silicone sheet, thermally conductive silicone cloth, thermally conductive gel, thermally conductive silicone grease, non-silicone oil thermally conductive gasket, carbon fiber thermally conductive gasket, etc. Most of the raw materials of thermally conductive gap filler contain silicone oil. Therefore, it is impossible to avoid the precipitation of small siloxane molecules during use, which will affect the performance and service life of the product.
There are gaps in the direct contact between the radiator and the heat source. No matter how smooth the surface is and how strong the pressure is, there will still be gaps, so use thermally conductive gap fillers. Most of the thermal conductive materials on the market are made of silicone oil as raw materials, so it is inevitable that small siloxane molecules will precipitate during use. Some industries and products require thermal conductivity materials that do not precipitate small siloxane molecules due to equipment environmental conditions. -Non-silicone oil thermally conductive gasket.
Electricity-driven machinery and equipment, such as mobile phones, computers, smart watches, and electric cars, are flooding all aspects of people’s lives, and they will inevitably generate heat during operation. If the temperature continues to rise and not drop, it may Will cause damage to the equipment, so why is it hot? Theoretically, the conversion of energy is conserved, but in reality, under the resistance of many factors, the conversion of energy is accompanied by time loss. When electric energy is converted into other target energy, it is accompanied by the occurrence of heat generation. The simple understanding is that when current passes through the resistance, it will be generated. Heat, but the space in the equipment is narrow, the air circulation is not smooth, the heat is not easy to dissipate and accumulate in a local location, causing the local temperature of the equipment to rise.
