LED light pole display how to reduce heat efficiently

For electronic equipment, heat and high temperature is a "fatal injury", how to cool the LED advertising machine, become a headache for the current LED light pole display advertising machine manufacturers, let's talk about how to cool the LED advertising machine!

1. Let the LED advertising machine be in a low load state

To solve a problem, it is necessary to understand from the source, why is the LED advertising machine hot? A large part of the reason is that the load is too large, so the LED advertising machine is in a low load state to effectively help the LED advertising machine to "cool down."

How to make the LED advertising machine under low load? The selected core card such as the sending card and receiving card must be close to 80 °C, and the area of ​​the transmitting card can be not too large. The memory 1G is enough to ensure that the main control card is in low power consumption and low load. Capacitors must reach the industrial level.

2, LED advertising machine needs to use a large power supply

The power supply is also a "main force" for the LED advertising machine. When the ambient temperature is 30 °C, the conversion rate of the outdoor LED advertising machine power supply is 90%, 60 °C is reduced to 60%, and when it reaches 80 °C, it is only 50%, so when the internal temperature rises, the conversion rate of the power supply drops rapidly, so the power supply must be increased. After the remaining amount, the heat of the power supply is also reduced, and the internal temperature is lowered.

3, LED advertising machine needs to use a large chip

In fact, the screen of the LED advertising machine is composed of LED lamp beads. Therefore, in order to control the heating temperature of the LED lamp bead, the LED advertising machine manufacturer must use a large chip to design the brightness of the LED advertising machine to 7000 cd or more. About 4500cd, the power supply, the driver chip, and the light-emitting chip are all in a light load state, and the energy consumption of each unit can be reduced at the same time.

4, LED light pole screen needs to meet the principle of thermal convection

In addition to the above-mentioned points, the internal layout of the LED led light pole video screen advertising machine is also very important, especially the placement of high-heat components such as sending cards, receiving cards, power supplies, etc., can not be prevented by their own preferences, and It is placed in the lower half of the cabinet, and the fan is placed on the top of the cabinet. At the same time, the internal wiring design should be horizontal and vertical. At this time, the shortest line is easier to achieve internal heat convection.

5, LED light pole video display needs to design the air outlet

In order to really cool the LED advertising machine, the air outlet and the fan must be indispensable. In addition, the box body should also be made of metal materials with good thermal conductivity. The air outlet and the air inlet should be designed as large as possible, and the number of fans should be increased. Reduce heat during daily use to avoid damage to the equipment.

As a professional LED light pole display advertising machine manufacturer, TBC focusing on high-quality LED advertising machine products, it also summarizes many application problems, and the serious consequences brought by high temperature to LED advertising machine is one of them. Therefore, LED advertising machine adopts intelligent LED heating and cooling integration temperature. The control system realizes automatic temperature sensing, comprehensively upgrades the aluminum material with good thermal conductivity, reduces the burden of high temperature, and carries a custom-developed 5V turbofan, and meets the outdoor environment temperature of -40 degrees to +70 degrees, making outdoor applications more reliable and more stable.
