How to Cool The LED Screen in Summer?

2021-07-21 www.myddisplay.com

With the development of economy and the continuous progress of society, led screens are more and more widely used. In the four seasons of the year, summer poses the greatest challenge to outdoor led screens, which must be moisture-proof and heat-dissipating. How to do a good job of preventing moisture in rainy weather while maintaining good heat dissipation in a high temperature environment has become a thorny issue facing outdoor led displays. So how do we dissipate heat for the led display?

1) LED displays also need fans and air conditioners

Summer is coming, for led displays, in addition to lightning protection, we must also pay attention to the high temperature weather in summer, especially outdoor led displays. In some provinces and cities, the outdoor temperature in summer is sometimes as high as 38°, 35°, and the led display still works continuously. Excessive temperature will cause its malfunction. How should we choose heat dissipation equipment for it in this hot summer?

As we all know, there are tens of thousands of tubes in the led display, the internal temperature is relatively high, and the screen is installed outdoors. In summer, the temperature is higher and needs to be cooled. In order to ensure the long-term stable operation of outdoor led displays, heat dissipation design can be said to be a top priority. Heat dissipation is to discharge the heat and hot air generated by the work in the led display in time to keep the air temperature in the led display and the working temperature of the device within the normal required range.

2) LED display within 20 square meters

1. For places north of Guangdong Province, it is recommended not to use air conditioners for LED displays within 20 square meters. If conditions permit, two small fans are sufficient.

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. It depends on the size of the installation space.

3) The led display more than 20 square meters

1. If your led display is installed against a wall, it depends on how much the display can protrude. If it can protrude by one meter from the wall, it is recommended to select the fan according to the size of the area, and the fan installation position is arranged in sequence above the side of the screen. If you buy an 80 square ph16 outdoor full color led display, it means that the fan you buy requires 6 axial fans with a diameter of about 600 mm. The fan is the kind that draws air outside, and when installing the fan, make sure that there is a protective net cover inside to prevent the technician from sucking in clothes or other things and causing injury when repairing the display. In order to be waterproof, aluminum alloy shutters should be installed on the air outlet of the fan on the outside aluminum-plastic panel.

The wall-mounted led display can also be equipped with an air conditioner. Make sure that the main unit of the air conditioner is placed in a place so as not to affect the overall appearance of the wall. The choice of air conditioner is required, and 1.5P, 2P and 3P air conditioners are generally used the most. Northern cities are calculated by 12 square meters of 1P air conditioners; southern cities are calculated by 9 square meters of 1P air conditioners. If the area of the outdoor led display is relatively large, the air conditioner should be customized directly by the manufacturer. If the area is not large, you can go to the specialty store to buy it.

2. If the led display is installed on a column, it is best to use a fan to dissipate heat. The fan is installed on the aluminum-plastic panel on the back of the big screen, and it is best to lean up and make it into the form of blinds so that when it rains, rain does not enter the screen. If it is a double column, open several shutters in the middle of the double column. This window is the air inlet, and the fan above is the air outlet, so that complete air convection is formed and the heat dissipation effect is better.
