Technology | summer is coming, how to heat the LED screen?

With the development of economy and the continuous progress of society, LED screen is widely used in daily life. In summer of the year, it is the biggest challenge for outdoor LED screen. Humid and high temperature weather makes LED screen damp proof and heat dissipation, which is a confrontation between the natural contradiction. How to do a good job of moisture-proof in rainy weather and keep good heat dissipation in high temperature environment has become a thorny problem for outdoor LED display. So how do we do a good job of LED display anti heat? The following small series to introduce how to do LED display heat dissipation.

LED display also needs fan and air conditioner

Summer is coming, for LED display, in addition to lighting, but also pay attention to the high temperature weather in summer, especially outdoor LED display. In some provinces and cities, the outdoor temperature is sometimes as high as 38 °， thirty-five °， LED display is still working, too high temperature will cause its poor operation, in this hot summer, how do we choose the cooling equipment for it?

As we all know, there are tens of thousands of light tubes in the LED display screen. The internal temperature is high, and the screen is installed outdoors. When the temperature is higher in summer, it needs to be cooled. In order to ensure the long-term stability of outdoor LED display, the heat dissipation design is the most important thing. Heat dissipation is to timely discharge the heat and hot gas generated by the work in the LED display screen, so as to keep the air temperature in the LED display screen and the working temperature of the device in the normal range.

LED display within 20 square meters

1. In the north of Guangdong Province, it is recommended not to use air conditioning for LED display within 20 square meters. If conditions permit, it is enough to use two small fans.

2. Some cities in the South: Guangdong, Guangxi, Hainan, Wuhan, Chongqing and other places need to install two fans. The diameter of the fan is about 500mm, depending on the size of the installation space.

A display with an area of more than 20 square meters

1. If your display screen is installed close to the wall, it depends on how much the display screen can protrude. If it can protrude one meter from the wall, it is recommended to select fans according to the size of the area. The fans are installed on the top of the side of the screen in turn. If you buy an 80 square PH16 outdoor LED full-color screen, That means you buy six axial-flow fans with a diameter of about 600mm. The fans are the ones that pump air from the outside. When installing the fans, make sure there is a net inside, so as to prevent the technicians who repair the display from sucking in clothes and other things when repairing the display, Aluminum alloy shutters should be installed at the air outlet of the fan on the outer aluminum plastic plate.

The display screen hanging on the wall can also be equipped with air conditioner. It is necessary to ensure that the host of the air conditioner is placed in a position, which does not affect the overall appearance of the wall. The choice of air conditioning is required. The most commonly used air conditioning is 1.5p, 2p and 3p. The calculation of 12 square 1p air conditioning in northern cities; In southern cities, 9 square 1p air conditioning is used. If the area of LED outdoor display is relatively large, the air conditioner will go to the manufacturer for direct customization. If the area is not large, it will go to the exclusive shop to buy, but the display cooling air conditioner has the function of power compensation.

2. If the installation method of LED display is column, it is better to use fan to dissipate heat. The fan is installed on the aluminum plastic plate on the back of the large screen, and it is better to lean up to make the shutter form, so that the rain does not enter into the display when it rains. If it is double column, open several shutters in the middle of the double column, and the Baiye window is the air inlet, The upper fan is the exhaust port, which forms complete air convection and makes the heat dissipation effect better.
