Abstract
A cooling device for a liquid crystal display monitor has a sealed container within which a light source is immersed in a thermally-conductive liquid coolant. The container is rigid and includes a transparent panel through which light travels from the light source to a display screen of the monitor. The liquid coolant transfers heat from the light source to the walls of the container, where it is transferred to the ambient environment. A flexible bladder is provided within the container, which is compressed by coolant volume increases resulting from heating of the coolant by the light source, thereby to protect the container from internal pressure stress. The bladder, filled with an easily compressible fluid, can be vented to the ambient environment, or can be fully contained within the container.
