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.
Automobile is a modern product that people often encounter or use. The energy it drives is fossil energy. In order to avoid the depletion of fossil energy in the future, the world has begun to vigorously promote new energy electric vehicles to reduce the need for fossil energy. Energy dependence while reducing environmental pollution, In the past, the technology of electric vehicles was not perfect, the battery life was insufficient, and problems occurred on the road. Now that the technology is gradually improved, many domestic and foreign automobiles have invested in the industry. It can be said that electric vehicles will become the mainstream of people’s future transportation. It is the energy that it drives. It needs to be charged when the power is insufficient, just like charging a mobile phone without electricity, and the charger of an electric car is called a charging pile.
Heating of equipment and equipment is a relatively common thing, and it is also a problem that people often encounter in daily life. There are many reasons for the heating of machinery and equipment, mainly because there is loss in the energy conversion process, and a large part of the loss is In the form of heat, the body heats up. Simply put, heat is generated when current passes through the resistor. In order to be able to effectively control the body temperature and ensure the stable operation of machinery and equipment. Under normal circumstances, a radiator is installed on the surface of the heat source to transfer heat to the radiator. However, if the radiator is directly installed on the heat source, the heat dissipation effect is very poor. Why does this happen?
The operation of electronic equipment is a process of energy conversion. In theory, there is no loss in converting electrical energy into other target energy and can be converted 100%. However, in reality, energy conversion cannot achieve 100% conversion, and there will be some energy. It is lost due to unavoidable factors, and in electronic equipment, much of the energy lost in this part is in the form of heat, which leads to heat generation during the operation of the electronic equipment. In order to avoid damage to machinery and equipment due to heat problems, a radiator is generally installed on the heat source to dissipate heat in a timely manner. It is not feasible to install the radiator on the heat source alone, which will cause poor heat dissipation, so both are required Fill the thermal conductive material between the gaps to fill the cavities between the gaps and remove the air between the gaps, thereby reducing the contact thermal resistance and improving the thermal conductivity.
Generally, a heat-conducting material needs to be filled between the radiator and the heat source to fill the large and small gaps in the gap and remove the air, so that the heat source and the radiator can be in close contact, improve the heat transfer efficiency, and achieve the effect of improving the heat dissipation effect. There are many kinds of thermal conductive materials on the market, such as thermally conductive silicone sheet, thermally conductive paste, thermally conductive phase change film, thermally conductive gel, non-silicon thermally conductive sheet, thermally conductive silicone cloth, etc. Each thermally conductive material has its own field and Features.
The heat generated during the operation of machinery and equipment is mainly because heat is generated when the current passes through the resistor, and the electrical energy cannot be completely converted during the conversion, and a part of the energy is lost, and heat is a larger part of it. The heat transfer efficiency in the air is low, and it cannot be quickly transferred to the outside without a special way, so it will accumulate on the surface of the heat source, and the temperature will rise over time and affect the performance of the machine.
The heat dissipation effect of the direct contact between the radiator and the heat source is very low. Even if people observe that there is no gap between the two, in fact, there are some gaps between the two, and the gap contains a lot of air, so the heat transfer efficiency will be reduced, so that The heat dissipation effect is not ideal. The thermal conductive material is to reduce the contact thermal resistance between the radiator and the heat source, eliminate the air in the gap, so that the heat source and the radiator can be in close contact, thereby improving the heat transfer efficiency.
When we as a business choose a thermally conductive silicone pad, we need to consider a number of factors, and besides thermal conductivity and cost, there are some other important considerations that need to be taken into consideration.
With the development of social science and technology, technology products have higher and higher requirements for thermal conductivity. Thermal silica gel sheets have appeared in our market. In fact, most people are still very unfamiliar with thermal silica gel sheets, but they only know about one of its functions. , The specific and more detailed knowledge is lacking, so I don't know where to start buying thermal silica gel sheets. So how do we choose when purchasing thermal silica gel sheets? What problems should we pay attention to? Under numerous specification parameters, these two problems have been bothering our relevant R&D and procurement personnel.
More and more vehicles are equipped with wireless chargers, which are easy to use and highly versatile, and avoid poor contact between charging plugs and charging sockets caused by frequent plugging and unplugging of data cables. However, one of the biggest problems in practical applications of wireless charging is heat dissipation. During the wireless charging process, because the coil at the transmitting end is oscillating, a large current is generated on the coil and a large amount of heat energy is generated at the same time, which makes the coil heat up, thereby affecting the charging effect.
The demand for computing power and bandwidth of data centers is increasing day by day, and the pressure on energy consumption is multiplying. High temperature is a performance killer of electronic systems and a potential reliability destroyer. The higher the temperature, the greater the power consumption and the lower the system performance. So controlling the temperature of server systems and associated electronics is critical for uninterrupted storage and processing of data.
ChatGPT is hot out of the circle, bringing new momentum to the development of the artificial intelligence industry.
Power supplies are very important components in both electronic devices and power systems. Commonly used power supply products include uninterruptible power supplies (UPS), PC power supplies for computers, switching power supplies for power distribution and control, power rectifiers for communications and lighting, driver power supplies for LEDs, etc. Power supplies generate a lot of heat when running at high power. If the heat cannot be dissipated in time, the temperature of the power supply will rise, which will affect the stability and reliability of the power supply, and even damage the power supply.
The popularization of assembled computers enables every household to have their own personal computer, through which they can play a variety of 3A game masterpieces or online multiplayer games, and when people play online games, they sometimes complain about the servers made of potatoes by game companies To describe the poor operating environment of the game.
People often come into contact with various electrical equipment in their life and work, such as our daily use of mobile phones, computers, electric vehicles, elevators, air conditioners... When electrical equipment is used, heat is generated, which is something people can Understand the phenomenon, and this situation cannot be avoided, so it is necessary to prepare for heat dissipation.
