Compared with large-screen TV, LCD splicing screen is more suitable for the development and needs of the times. It is an independent and complete display unit, which can be hung and used at any time. Installation is as simple as building blocks. The use and installation of single or multiple LCD splicing screens are very simple. The digital processing technology used in LCD splicing series products is intended to let users really experience the full HD big screen effect. For the coming summer, the heat dissipation problem of LCD splicing screen has to be faced squarely. In the face of high temperature climate, we can cool down by turning on the air conditioner, fan and drinking cold drinks. However, splicing the screen still requires continuous work 7x24 hours a day. What are the methods of cooling and dissipating heat for splicing screens?
Heat dissipation of LCD splicing screen
The cooling mode of LCD panel can be divided into automatic cooling and passive cooling. The former forcibly takes away the heat emitted by the radiator through heat dissipation equipment such as an electric fan, while the latter naturally diffuses the heat of the large-screen splicing commercial light source as a heat source into the air through the radiator. In practice, automatic heat dissipation methods can be subdivided into air cooling, liquid cooling, heat pipe cooling, semiconductor cooling, chemical cooling and so on. High heat dissipation power and small equipment volume; Passive heat dissipation method, whose heat dissipation effect is proportional to the size of the heat sink, is mainly used to dissipate heat for equipment with no space requirements or components with small heat generation. Generally speaking, if you want to use LCD splicing screen normally, the optimal temperature is 0~42 degrees. In practice, when LCD splicing screen is used in indoor environment, relatively efficient automatic heat dissipation method will be the first choice. Industrial users can control the temperature by using air conditioning equipment, and the temperature is usually controlled between 25 and 26 degrees.
LCD splicing screen not only needs heat dissipation, but also needs dust removal.
In the working state of LCD panel, the lighting temperature can be as high as 1000 degrees, while the working temperature of many equipment inside the unit is below 70 degrees Celsius, which will become more and more severe in high temperature environment. In this case, professional users first choose air cooling mode to cool down and dissipate heat. It is worth noting that although this method can achieve a certain cooling effect, it is easy to bring dust from the air into the equipment during operation. Therefore, in the heat dissipation process of LCD panel, in addition to physical cooling operation, attention should also be paid to dust removal of equipment regularly. In addition, LCD splicing screen is also very easy to stick dust and fingerprints, so don't wipe it with paper towels and wet cloth, which will make the screen wear and tear, and it is easy for water stains to enter the machine and cause failures. Dust on the screen must be wiped with a special dust-proof cloth.
In addition, the service life of LCD splicing screen bulbs is limited. Light bulbs that have exceeded their service life are easy to explode if they continue to be used. Therefore, when used in high temperature environment in summer, users must pay attention to the inspection of light bulbs. After a period of use, if the brightness of the light bulb is greatly reduced, it is a warning that the light bulb has passed its service life.
