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.

Abstract: A method and mechanism for cooling a display device 200, having an extremely bright light focused on its surface and is mounted inside a closed chassis, by conducting heat 220 from the device directly to the chassis walls 212, where the heat is then transferred 222 to the lower temperature air of the ambient surroundings. The mechanism uses an adjustable mechanical linkage 208 to close the gap 214 and make a good thermal contact between the projection device package 200 or heat sink stud 206 and the chassis wall 212. This approach reduces the requirements for large heat sinks and noisy cooling fans found in many conventional projection systems.
