Abstract
A thermal management system is for utilization in a compact display device. A duct is provided within the lamp housing of the display device and a high-wattage light source is mounted within the duct. Multiple cooling fins are mounted to at least one inner surface of the duct and extend into the duct. A thermal radiation absorbent coating, such as black anodization, covers the interior of the duct and the cooling fins and provides for an increased surface absorption of thermal radiation. A port within the duct, which is transparent to visible light, is utilized to direct visible light through a display assembly. An infrared filter, which is reflective or absorptive of infrared radiation, such as a so-called 'hot mirror' is utilized to maintain thermal radiation within the duct and a fan is then utilized to pass cooling fluid through the duct, passing the cooling fluid over the cooling fins and removing thermal energy from the display device in a highly efficient manner.
