Selection skills of LED display cooling device
1. Small LED display screen below 20 square meters
A 20 square LED display is a indoor fine pitch LED display. Most of the time, two small fans are enough for a small LED display. The diameter of the fan is about 500mm, which can be determined according to the size of the installation space.
2. LED display with an area greater than 20 square meters
LED displays larger than 20 square meters are generally called large and medium-sized LED displays. The heat dissipation of these screens is a very important issue. Of course, the installation method is different, and the selected heat dissipation method is also different.
1. If your display screen is installed 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 size of the area. The fan installation position is on the side of the screen. If you buy an outdoor LED full-color screen with a ph16 size of 80 square meters, it means that the fans you buy need 6 axial fans with a diameter of about 600mm, and the fans are exhausted to the outside. That kind, and when installing the fan, make sure that there is a net inside, to prevent the technicians who repair the display screen from sucking clothes and other things into the body when repairing the display screen. The air outlet of the fan is equipped with aluminum alloy shutters.
2. If the installation method of the LED display is to use a column, then it is best to use a fan to dissipate heat. The fan is installed on the aluminum-plastic panel on the back of the large screen. It is best to lean up and make it in the form of shutters to facilitate the rain. Rainwater does not enter the display screen. If it is a double column, open a few shutters in the middle of the double column. This Baiye window is the air inlet, and the fan above is the exhaust port, which forms a complete air convection and makes the heat dissipation effect. better.
The wall-mounted display screen can also be equipped with air conditioners. It is necessary to ensure that the main unit of the air conditioner has a place to place it without affecting the overall appearance of the wall. There are requirements for the choice of air conditioners. Generally, 1.5P, 2P and 3P air conditioners are the most used. The calculation of 12 square 1P air conditioners in northern cities is calculated by 9 square 1P air conditioners in southern cities. If the area of the LED outdoor display is relatively large, the air conditioner should be customized directly by the manufacturer. If the area is not large, it should be purchased at a specialty store, but the display cooling air conditioner has the function of compensation for incoming calls.
