Abstract
This paper describes cooling performance for panels in liquid crystal projector. We divide a light from the lamp into three parts. Those are R (red), G (green) and B (blue). We have three optical components in R, G and B, severally. We consider the three optical components as the parallel plates. Both the pressure drops between the inlet and the exit in the parallel plates, and the mean heat transfer coefficients between the parallel plates are calculated. The gap between the parallel plates is optimized once we use a fan in the liquid crystal projector. In this paper, the optimum gap is 1.1-1.2mm. The temperatures in the three optical components for R, G and B are predicted.
