China has put forward many policies to vigorously develop energy-saving and environmental protection LED video display products. However, due to the high cost of LED electronic panels, there are a series of questions, such as the lack of standards, the need to improve the cooling performance, and the re planning of power drive demand. Here, let’s talk about the heat dissipation problem of LED electronic screen.
1、 LED electronic screen within 20 square meters
1. For the local area to the north of Guangdong Province, 20 square meters of LED display advocate not to use air conditioning, if conditions permit, the use of two small fans is enough.
2. In some cities in the South: Guangdong, Guangxi, Hainan, Wuhan, Chongqing and other local needs, it is enough to install two fans. The diameter of the fans is about 500mm, which depends on the size of the installation space.
2、 Electronic screens with an area of more than 20 square meters
1. If your display device orientation is close to the wall, you can see how much the display can protrude. If you can protrude one meter from the wall, it is suggested to select fans according to the size of the area. The fan device orientation is arranged in sequence on the top of the side of the screen. If the display screen you buy is p16 outdoor LED electronic screen with an area of 80 square meters, it means that you need 6 fans with a diameter of 600 For axial flow fan with diameter of about mm, the fan is the type that exhausts air from the outside. When installing the fan, make sure that there is a net inside, so as to avoid the technician repairing the display screen from sucking in other things to cause personal injury. In order to prevent water, install aluminum alloy blinds on the air outlet of the fan on the outer aluminum plastic plate.
The wall mounted electronic screen can also be installed with air conditioner. It is necessary to ensure that the host of the air conditioner is positioned in a certain direction, which does not affect the overall appearance of the wall. The selection of air conditioning is requested. The most commonly used air conditioners are 1.5p, 2p and 3P, with the air conditioning accounting of 12 square meters in northern cities and 9 square meters of 1p air conditioning in southern cities. If the area of LED outdoor electronic screen is relatively large, the air conditioner will go to the manufacturer to order directly. If the area is not large, you should go to the exclusive store to purchase, but the electronic screen cooling air conditioner has the function of calling compensation.
2. If the installation method of LED electronic screen is column, the best choice is fan for heat dissipation. The fan is installed on the aluminum plastic plate on the back side of the large screen. It is best to lean up and make blinds so that the rain does not enter the electronic screen when it rains. If it is a double column, open several louvers in the center of the double column. The Baiye window is the air inlet The fan is the exhaust port, which forms a good air convection and makes the heat dissipation function very good.
If you request it is necessary to install air conditioning, there is no doubt about this. The cost of purchasing and using should be added, and the cooling effect will be worse than that of fans. There is another question, if you want to install air conditioning, it is necessary to think about a question, that is, where the external unit is installed, whether it is hung on the column or on the reverse side, whether it can ensure the appearance of beauty.
