With the arrival of summer, high temperature weather makes maintenance of many outdoor LED electronic displays more difficult. How can the outdoor full-color LED display be not affected by high temperature and dissipate heat reasonably on a hot summer day? The following authors give recommendations for heat dissipation for LED displays with an area of ​​less than 20 square and more than 20 square.
How to dissipate heat of LED display within 20 square
1. For the area north of Guangdong Province, it is recommended not to use air conditioners for LED displays within 20 square feet. 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, depending on the size of the installation space.
How to dissipate heat for LED display with more than 20 square meters
1. If the LED display installation position is against the wall, it depends on how much the LED display can protrude. If it can protrude from the wall by one meter, 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 Lined up in order. If the LED display purchased by the customer is a P16 outdoor LED full-color screen of 80 square meters, six axial fans with a diameter of about 600mm should be selected. Special attention should be paid to ensure that the fan is pumping outside, and a protective net is installed to prevent the technician who repairs the display screen from sucking clothes into it when the display screen is being repaired to take personal injury. In addition, it is necessary to install aluminum alloy shutters on the air outlet of the aluminum-plastic plate on the outside to achieve the waterproof effect.
The full-color LED display on the wall can also be equipped with air-conditioning. It is necessary to ensure that the main unit of the air-conditioning is placed in a position that does not affect the overall appearance of the wall. The choice of air-conditioning is required. The most commonly used are the 1.5P, 2P and 3P air-conditioning. The northern city is 12 square meters 1P air conditioner calculation; the southern city uses 9 square 1P air conditioner calculation. If the area of ​​the LED outdoor display is relatively large, the air conditioner will be customized directly by the manufacturer. If the area is not large, it will be purchased at a specialty store, but the display cooling air conditioner has a call compensation function.
2. If the installation method of the LED display is a column, it is best to use a fan to dissipate heat. The fan is installed on the back of the aluminum-plastic board on the back of the large screen. It is best to lean it up and make it in the form of shutters to facilitate rain. Rainwater does not enter the display. If it is a double-column, several blinds are opened in the middle of the double-column. This louver is the air inlet, and the fan above is the exhaust, so that a complete air convection is formed to make the heat dissipation effect better.
The maintenance plan of the full-color LED display is a measure for heat dissipation, and the second is to avoid improper operation during use. It is generally recommended to configure a fan or air conditioner to enhance the cooling function.
