Benefits of Outdoor LCD Cooling System
Outdoor lcd offers benefits over traditional methods that make it a cost effective solution in many cases and now it's becoming the popularity of this engaging and dynamic digital marketing medium becomes mainstream.
outdoor digital signage displays is able to withstand both hot and cold surroundings, Internal air-cooling system or air-conditioning systems can be customized to allow the display to work at an optimal level in almost any climate.
Outdoor digital signs prevent all airborne swarf, dust and other particles; broadening the range of possible environments, prevent dust, debris and moisture from the air entering with IP65 level(some model even with IP66 level). And digital signage outdoor displays screens is using high brightness with 2500-5000 cd/m2.
As we all knows , the cooling system is very important for outdoor digital signage. Outdoor digital signage totem usually put outside, there will be strong sunlight, bring a lot of heat, especially in summer, long time overheating, If without outdoor cooling system, the outdoor screens can't display content normally, the outdoor screen will get black spots, even can burn the screen in serious cases, that would make outdoor display broken.
So outdoor cooling system is vital for outdoor screen equipment. Considering this points, Marvel Independent research and development own cooling solutions, We make outdoor advertising player screen comes with ventilations holes in up and down. The air inlet and outlet are designed with a special dust-proof filter (efficient dust-proof filter) to filter fine dust in the air and prevent mosquitoes from entering the inside of the machine. The down ventilations is for sucking cooling air into the screen, the up ventilation holes is for exhausting hot air out. And the cooling air will blow the heating in the surface of the LCD panel via the cooling air going through the front space of LCD panel. All external air enters the filter first, and divides the wind into two air ducts before and after the screen.
When the internal temperature is high due to special circumstances such as blocked inlet and outlet air ducts and other special circumstances that are not detected and maintained in time, the system will turn off the power of the LCD screen, and the air-cooled system will continue to operate normally to cool down to protect the LCD screen, motherboard and other major components.
In some areas, the temperature will be very hot in summer, such as the Middle East (Israel, UAE and Arab regions), it is usually recommended to use air conditioning cooling system, which can be combined with an outdoor operation and maintenance cloud system, when outdoor device working with high temperature (The air conditioner working temperature is manually set, you can set it by yourself to maintain a constant temperature), the air flow cooling system will working.
Besides Marvel build up intelligent temp management module inside the outdoor screen, when the inside temp is up, the cooling fans will speed up , otherwise ,the cooling fans speed will slow down or keep constant speed to make screen with low power consumption. What is the most important that Marvel also has configure the outdoor digital signage with filter detective percentage sensor, the sensor will tell you how's the status of the filer block percentage.
With over 12 years experience in outdoor digital signage field, we know if the filter is blocked, the cooling system will break down. That's why all of our outdoor screen builds up OMC to monitor the outdoor signs. And the OMC can control the screen to do self-diagnosis when distributed to different location.And users are free to know the status of all screens easily whenever and wherever they are. For the cooling system can be used outdoor screens, And marvel can provide the API and all kinds of sensors to detect the environmental data.
OMC with 10 kinds of sensor: --Light sensor --Screen sensor --Humidity sensor --Temperature sensor --Door sensor --Ponding sensor --Smoking sensor --Current sensor --Tilt sensor--Filter sensor.
Each sensor with specific function. See more information please contact marvel freely!
