AI Technical Summary
Existing technologies for cooling digital micromirror devices (DMDs) have problems such as system complexity, bulkiness, high cost, prone to condensation accumulation, and the need for external equipment maintenance, making it difficult to achieve an efficient and compact cooling solution.
A stacked structure of vapor chambers and cooling units is adopted, with the vapor chambers facing the feet of the DMD and the cooling units facing the back surface of the DMD. Peltier elements and cold plates are used for efficient cooling and are integrated into the projector, avoiding external freezers and air dryers.
A cheaper, simpler, more reliable, compact, lightweight, and faster-starting cooling solution is achieved, which reduces maintenance requirements, improves the ecological performance of the projector, avoids condensation dripping, and reduces the impact on the environment.
