Outdoor fixed led billboard how to cool down efficiently

In the process of using outdoor fixed led billboard LED full-color display, the overall power is large, especially for the LED large screen, the power is higher. Fire safety hazards caused by heat dissipation problems are also worthy of caution. At the same time, heat dissipation also helps to extend the life of the screen. For the LED full-color display of different areas to select the cooling device, you can refer to the following:

   One, 30 square meters of outdoor fixed led screen full-color display

   1. For areas north of Guangdong Province, it is recommended not to use air conditioners because there is no hot weather. If conditions permit, it is enough to use two small fans.

   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 determined according to the size of the installation space.

   Second, the outdoor fixed led sign full-color display area of ​​more than 30 square meters

   1. If the display is installed against the wall, first determine how much the display protrudes. If the position of the wall is one meter, it is recommended to select the fan according to the size of the area. The fan installation position is arranged above the side of the screen. For example, the customer has customized a 50-square-meter P16 outdoor full-color LED display in Lianchengfa. It is conceivable to install four axial-flow fans with a diameter of about 600mm. The fan is the one that draws air to the outside. The fan outlet on the board is fitted with aluminum shutters.

   2. If the outdoor fixed LED display is installed with a column, use a fan to dissipate heat. The fan is mounted on the back of the large-screen aluminum-plastic panel, preferably up. If it is a double-column, open a few louvers in the middle of the double-column as the air inlet, and the upper fan is the exhaust port to form complete air convection so that the heat dissipation effect is better.

   3. If the display is mounted on a wall, air conditioning can be installed, but the purchase cost and the cost of use will increase, and the heat dissipation effect will be worse than that of the fan. In addition to air conditioning, the air conditioning host must be placed in a position that does not affect the overall appearance of the wall. The most commonly used air conditioners are 1.5P, 2P, and 3P. The northern city is calculated according to 10 square meters 1P air conditioner; the southern city is calculated by 8 square meters 1P air conditioner. If the area of ​​the LED outdoor display is really large, it is more than 100 square meters, the air conditioner will go directly to the manufacturer to order if the area is not big, you can go to the store to buy, but the air conditioner must have call compensation function.

   The above is about the selection of outdoor fixed led billboard LED full-color display cooling equipment, combined with the screen area, installation location weather, installation methods, etc., which can better solve the heat dissipation problem, thus eliminating safety hazards, ensuring stable use and life of the display.
