ATLANTA, Ga. — Manufacturing Resources International Inc. (MRI) has announced a new cooling system for Outdoor Digital Displays that allows for operation in ambient temperatures up to +50ºC (+122ºF), even in direct sunlight conditions.
The patent-pending CoolVu TMS (Thermal Management System) has been developed by MRI using EFD (engineering fluid dynamics) to model air flow and cooling performance based on ambient temperature conditions and the impact of direct sun load on the LCD screen, running at 2000+ nit brightness. It is designed exclusively for MRI’s line of newly released BoldVu digital displays ranging from 32- to 82-inch diagonal in size.
This energy-efficient cooling system is achieved without the use of air conditioners or thermo-electric coolers and without the introduction of external ambient air over any optical surfaces or electrical components. All electronics, display surfaces, optical films and backlight assemblies are contained in a sealed, cool, dry and clean environment thereby prolonging the life of the electronics and significantly reducing field failures and associated maintenance costs.
In addition, the LCD surface is maintained at a safe temperature thereby preventing solarclearing, which results in black spots on the LCD surface or a completely blackened screen with prolonged sun exposure.
