With the development of the LED display industry, small, ultra -thin, and lightweight has become an important direction for the development of the industry. With the miniaturization and lightness of the equipment, there are no large -volume heat dissipation fans and water cooling heat dissipation structures. By reduce the damage to high fever and its parts.
For the indoor LED display, there seems to be some harmful factors because there is no threat of sunlight. However, correspondingly, the indoor demand for the lightness of the product is higher, and the available heat dissipation pair space around the product is limited. These factors make indoor equipment heat dissipation.
Today's LED display equipment is divided into metal heat sinks, heat pipes, fans, water cooling and other methods. The first two are passive heat dissipation. The latter two are active heat dissipation. The so -called active heat dissipation and passive heat dissipation are mainly based on the need to provide additional electricity without providing additional electricity to define heat dissipation.
Heading tablets are the most typical passive heat dissipation components. In addition, Heat Pipe is also the increasingly popular passive heat dissipation element in recent years. In the field of heat dissipation, the high -heat conduction coefficient is still the main direction of technological development to guide heat to guide heat to guide heat Good sex, light quality, and easy -to -process metal such as aluminum or copper, and the better silver with better thermal conductivity is too expensive and usually not adopted. We use it in daily life, and we will also assist with the heating cream, such as the "silicone" inside our common computers.
The thermal pipe is another heat dissipation solution that is more common passive way. The characteristics of light and fast the average temperature of quality, which make it have excellent thermal conductivity characteristics. The use of thermal pipes is quite wide. Today, it is popularized in different application areas such as heat exchangers, coolers, etc., playing the role of heat transfer and heat dissipation.
The most common active heat dissipation is to use the motor to drive the wind and cold heat dissipation of the fan blades. In addition to the most common computer case and the power supply device, combine with the heat sink and thermal pipe into a composite heat dissipation device. It is widely used on important computer processors such as graphics cards, central processors.
Water -cooled heat dissipation refers to the calorie of the radiator with the use of the liquid under the drive of the pump. Compared with the wind and cold, it has the advantages of quietness, cooling stability, and small environmental dependence on the environment. The heat dissipation performance of the water cooling radiator is directly proportional to the current rate of the radiator (water or other liquid), and the flow rate of the refrigeration solution is related to the water pump power of the refrigeration system. Moreover, the heat of water is high, which makes the water -cooled refrigeration system has a good heat load capacity. It is equivalent to 5 times the air -cooled system, and the direct benefit is that the temperature curve of the relevant component's work is very gentle. For example, a system that uses wind and cold radiator will appear in a short period of time when running a CPU load is large, or it may exceed the CPU alert temperature, while the water cooling and heat dissipation system is relatively small, the heat fluctuations are relatively small, and the heat fluctuations are relatively small. It's much more.
