Conventional Structure

A low-noise and high-performance “inclined fan-blowing-upward structure” for full high definition plasma display panel television sets was developed by using computational fluid dynamics with heat transfer based on a Cartesian grid system. In the conventional structure, the plasma panel and boards are cooled by fans and upward flow induced by natural convection. However, simulation results indicated that low-temperature flows between the bottom and rear inlets and fans are formed along the back cover, and the flows are not sufficiently supplied to the plasma panel and address-driver modules. Our solution is to mount the cooling fans inclined to the plasma panel so that the flows produced by the fans impinge on the panel to supply the low-temperature air to the panel and address-driver modules directly. In the new structure, larger fans can be used because fans are mounted inclined. With the larger fans, the rotation speed of the fans can be reduced, and the flow rate is increased. The experimental results show that the temperature of the panel and address-driver modules decreases respectively 3C and 8C at the same noise output level.

Zno Powder

Aluminum doped ZnO crystal powders have been successfully prepared by sol-gel method with low temperature (150°C) crystallization process. The AlNO3 as material dopant were varied by 0.5 wt% and 1.0 wt% relate to 5 mmol of zinc acetate dihydrate as precursor. Degradation of the methylene blue (MB) was used to evaluate the photocatalytic property. The results showed that all ZnO samples have spherical morphology with hexagonal wurtzite crystal structures. The ZnO powder with 0.5 wt % of aluminum has a better photocatalytic property that related to the optical characteristics. The optimum of Al content (0.5wt%) reduces the crystallite size and give some advantages in optical characteristics that directly relate to the increments in photocatalytic behavior. The photodegradation rate of Al doped ZnO 0.5 wt% is increase almost 100% compared with ZnO undoped. The stability and reusability of 0.5 wt% Al doped ZnO as photocatalyst, is also observed by monitoring the photocatalytic behavior under 14 hours irradiation (in three recycle used)
