Discussion on the heat dissipation solution of LED full color display

near 40 degrees high temperature, is the LED full-color display still working normally?” we have to sigh how important it is to make a good heat dissipation solution for the customer’s LED display screen! Here, we recommend wall mounted and column mounted cooling solutions.

First, the explanation of common heat dissipation methods

1. Air hydrodynamics, using the shape of lamp shell to produce convection air, is the lowest cost way to strengthen heat dissipation.

2. Thermal conductive plastic shell, which is filled with thermal conductive materials during injection molding, increases the thermal conductivity and heat dissipation capacity of the plastic shell.

3. Aluminum fin, which is the most common way of heat dissipation, is used as a part of the shell to increase the heat dissipation area. [large electronic display screen]

4. The surface radiation heat treatment, the lamp shell surface to do radiation heat treatment, the simple is to paint radiation heat dissipation paint, can take the heat away from the lamp shell surface by radiation.

2. Wall mounted and column mounted cooling solutions

If the installation method of LED display screen is column, it is better to use fan for heat dissipation. The fan is installed on the aluminum plastic plate on the back of the large screen, and it is better to lean upward to make the form of louver, so that the rain water will not enter the display screen when it rains. If it is a double column, a few blinds should be opened in the middle of the double column. The Baiye window is the air inlet, and the fan above is the exhaust port. In this way, complete air convection is formed and the heat dissipation effect is better.

2. [vehicle LED display] if the installation position of LED display is close to the wall, it depends on how much the LED display can protrude. If it can protrude one meter from the wall, it is recommended to select the fan according to the area, and the fan installation position should be arranged above the side of the screen. If the LED display screen purchased by the customer is p16 outdoor full-color LED screen with an area of 80 square meters, six axial-flow fans with a diameter of about 600 mm should be selected. Special attention should be paid to ensure that the fan is pumped out and equipped with protective net, so as to prevent the technicians repairing the display screen from sucking in clothes and causing personal injury. In addition, the air outlet of the fan on the outside aluminum plastic plate should be installed with aluminum alloy blinds, which can achieve the waterproof effect.

The full-color LED display screen hanging on the wall can also be installed with air conditioner. It is necessary to ensure that the host of the air conditioner is placed in a position, which does not affect the overall appearance of the wall. The selection of air conditioning is required. Generally, 1.5p, 2p and 3P air conditioners are used most, and the air conditioning calculation of 12 square 1p air conditioning in northern cities and 9 square 1p air conditioning calculation in southern cities are adopted. If the area of LED outdoor display screen is relatively large, the air conditioner will be directly customized by the manufacturer. If the area is not large, you should go to the exclusive store to buy it. However, the display panel cooling air conditioner has the function of calling compensation.
