A system of numerical flow simulation with an automated mesh generator and parallelized solver was applied to the flow field inside flat panel displays. A uniformly spaced Cartesian grid was used to reduce the simulation time and to automatically generate a mesh from CAD data for complicated geometries such as in a PDP set. Comparison of the simulation results between a fan-less model and a fan-equipped model is the first step in developing more efficient cooling structures. The high temperature region inside the upper body of the fan-equipped model was reduced relative to that of the fan-less model, but the temperature difference between the upper and lower regions still remained. The results also showed that other high-temperature regions formed where a panel module faced a large circuit board, since cooling flow was obstructed by frames, cables, etc.
