Analysis of Heating System for PDP Panel Using $RADCAD^{TM}$

Analysis of radiation heating system for producing 60" size PDP panels was carried out using $RADCAD^{TM}$ software. Optimum arrangement of infrared heating elements was found to obtain uniform temperature distribution in PDP panel during heating. Heating capacity of each heater was determined to obtain an appropriate maximum panel temperature. Parametric study to find the effect of design parameters such as the thermophysical and optical properties of glass and cooling system was carried out. As a reference system, about 35 kW heating capacity was chosen to obtain about 800 K maximum panel temperature after 30 minute heating. The maximum temperature difference in panel was below 20 K. The maximum/minimum and its difference in the panel were very sensitive to the variation of the emissivity of glass and cooling block.
