ABSTRACT:
A method and mechanism for cooling a display device, having an extremely bright light focused on its surface and is mounted inside a closed chassis, by conducting heat from the device directly to the chassis walls, where the heat is then transferred to the lower temperature air of the ambient surroundings. The mechanism uses an adjustable mechanical linkage to close the gap and make a good thermal contact between the projection device package or heat sink stud and the chassis wall. This approach reduces the requirements for large heat sinks and noisy cooling fans found in many conventional projection systems.
