Summer is coming, how to make LED screen cool better?
Jul 01, 2021
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?
01
The LED display also needs to blow fans and air conditioning
Summer comes, for LED display, in addition to lightning, but also pay attention to the summer high temperature weather, especially outdoor LED display. Outdoor temperature in some provinces and cities sometimes reaches 38 in summer °，LED display still works constantly, too high temperature will cause its operation is bad, how should we choose the equipment for heat dissipation in this hot summer?
As we all know, there are tens of thousands of light tubes in LED display, with high internal temperature and outdoor screen. In case of higher temperature in summer, it needs to cool down. In order to ensure the long-term stable operation of outdoor LED display, the heat dissipation design is a vital life. Heat dissipation means that heat and hot air generated by work in LED screen are discharged in time to keep the air temperature and device working temperature in the normal range of requirements.

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.
03
A display with an area of more than 20 square meters
1) If your display is installed close to the wall, it depends on how much the display 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. In order to prevent water, aluminum alloy shutters shall be installed at the fan outlet on the outer aluminum plastic plate.
In order to prevent water, aluminum alloy shutters shall be installed at the fan outlet 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 window-blinds is the air inlet, and the upper fan is the exhaust port, which forms complete air convection and makes the heat dissipation effect better
