In hot summer, not only do we humans need to prevent high temperature, but also other things, especially electronic devices. today LED display manufacturerLet's talk about how to choose the heat dissipation device of LED display screen:
　　
1、 Small LED display screen with less than 20 square meters
　　
A 20 square meter LED display screen is a small LED display screen. Most of the time, two small fans are enough for a small LED display screen. The diameter of the fan is about 500mm, which can be determined according to the size of the installation space.
　　
2、 LED display screen with an area greater than 20 square meters
　　
The LED display screen with an area of more than 20 square meters is generally called large and medium-sized LED display screen. The heat dissipation of these screens is a very important problem. Of course, the different installation methods also have certain differences in the selected heat dissipation methods.
　　
1. If the installation position of your display screen is near 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 the fan according to the area. The installation position of the fan is arranged above the side of the screen in turn. If the display screen you buy is an 80 square PH16 outdoor LED full-color screen, it means that you need 6 axial flow fans with a diameter of about 600mm, The fan is the kind that exhausts air to the outside, and when installing the fan, ensure that there is a net inside, so as to prevent the technicians who repair the display screen from sucking clothes and other things into it to hurt people. In order to be waterproof, install aluminum alloy shutters on the fan outlet on the outer aluminum-plastic plate.
　　
2. If the installation method of LED display screen adopts columns, it is best to use fans to dissipate heat. The fans are installed on the aluminum-plastic plate on the back of the large screen. It is best to lean up and make them into the form of louvers so that the rain does not enter the display screen when it rains. If it is double column, open several louvers in the middle of the double column. This Baiye window is the air inlet, and the fan above is the exhaust port, In this way, complete air convection is formed, which makes the heat dissipation effect better.
　　
The display screen hanging on the wall can also be equipped with an air conditioner. It is necessary to ensure that the host of the air conditioner has a position, which will not affect the overall appearance of the wall. There are requirements for the selection of air conditioners. Generally, the most commonly used air conditioners are 1.5p, 2p and 3P, and the calculation of 12 square 1p air conditioners in northern cities; Southern cities use 9 square meters of 1p air conditioning. If the area of the LED outdoor display screen is relatively large, the air conditioner will be directly customized by the manufacturer. If the area is not large, you need to buy it in a specialty store. However, the display cooling air conditioner has the function of call compensation.
