How to improve the heat dissipation effect of outdoor LED display?
With the continuous advancement of society and technology, new products have been developed in the field of display screens in our country, and LED displays are one of the most popular ones. With the increase in product demand over the years, the number of LED displays has also increased. The market size has also gradually grown. As we all know, LED displays will generate a lot of heat during use, especially outdoor LED displays, which will consume a lot of power. Therefore, if you want to reduce power consumption, you must dissipate more heat. Next, I will explain to you which methods can improve the heat dissipation effect of LED display.
1. The simplest method is to use a fan to dissipate heat. The heat dissipation effect can be enhanced by using a long-lasting and efficient fan inside the lamp housing. This method is relatively low-cost and has better effects.
2. Use aluminum heat dissipation fins, which is the most common way of heat dissipation. Use aluminum heat dissipation fins as part of the shell to increase the heat dissipation area.
3. Heat pipe heat dissipation. Heat pipe technology is used to conduct heat from the LED display chip to the heat dissipation fins of the housing.
4. Surface radiation heat dissipation treatment. The surface of the lamp shell is subjected to radiation heat dissipation treatment. The simpler method is to apply radiation heat dissipation paint, which can take the heat away from the lamp shell surface by radiation.
5. Thermal conductivity and heat dissipation integration - the use of high thermal conductivity ceramics. The purpose of heat dissipation of the lamp housing is to reduce the operating temperature of the LED high-definition display chip. Since the expansion coefficient of the LED chip is very different from that of our common metal thermal conductivity and heat dissipation materials, The LED chip cannot be welded directly to avoid high and low temperature thermal stress from damaging the LED display chip.
6. Air fluid mechanics uses the shape of the lamp housing to create convection air, which is the most cost-effective way to enhance heat dissipation.
7. Thermal conductive plastic shell is filled with thermally conductive material when the plastic shell is injection molded, thereby increasing the thermal conductivity and heat dissipation capacity of the plastic shell.
It can be seen that the maturity and progress of LED display heat dissipation technology will be conducive to its conservation and environmental protection concepts. LED electronic display manufacturers have various methods to improve the heat dissipation of LED displays in the production of LED displays. There are different considerations when dissipating heat depending on the power level and the place of use.
Indoor LED displays are used in indoor environments, and the brightness requirements are not high, generally 600-1000CD, so the heat generated is not large, and in the summer, the air conditioner is basically turned on indoors, which has a great impact on the heat dissipation of the screen. benefit. The LED transparent screen adopts a light bar design, and the flow of hot air naturally dissipates heat. Moreover, the LED transparent screen is generally installed indoors for outdoor viewing, and the indoor air conditioner also plays a big role in cooling it. What requires more heat dissipation methods is the outdoor LED display. When installing the outdoor LED display, if the area is relatively large, an air conditioner will be installed inside the screen to cool down.
