Summer is hot and hot, not only people need to take heatstroke prevention measures, as the most popular outdoor display equipment, LED display also needs heatstroke prevention and cooling to work properly. So, how do we choose the heat dissipation equipment for the LED display? Due to the different installation areas, different sizes, and different installation methods of LED display screens, the equipment selected depends on the actual situation. The following authors have collated several common heat dissipation solutions to provide reference:
1. LED display within 20 square meters
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.
2. Display with an area over 20 square meters
1. If the installation position of your display is against the wall, it depends on how much the 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 installation position of the fan is on the side of the screen If you buy an outdoor led full-color screen with an 80 square ph16 LED display, it means that the fan you buy needs 6 axial fans with a diameter of about 600mm. The fan draws air outside That kind, and when installing the fan, make sure that there is a net inside to prevent the technician who repairs the display screen from sucking other things in the clothes when the display screen is repaired to take care of personal injury. The fan outlet of the fan is equipped with aluminum alloy shutters.
The display on the wall can also be equipped with air conditioner. Make sure that the main unit of the air conditioner is put in place without affecting 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 upper fan is the exhaust. This forms a complete air convection to make the heat dissipation effect. better.
If you have to install an air conditioner, there is no problem. Both the purchase cost and the use cost will increase, and the cooling effect will be worse than the fan. There is another question. If you want to install an air conditioner, one of the questions you must consider is whether the external unit is installed, whether it is hung on the post or on the back, whether it can guarantee the beautiful appearance.
