Recently an effective energy management technique becomes important in an OA machine design for accumulation of several parts and compact size. Especially, heat control of the machine is necessary to keep the good quality of precise image in copier or printer. PSU(Power Supply Unit) is one of the highest temperature parts in the copier.
Thermal plume of the natural convection from the PSU is analyzed by the thermal vision using infrared light with an aid of the wire-net method. Also, the flow field of the thermal convection from the PSU is visualized using smoke-wire technique, PIV method is applied to these images to determine the quantitative flow velocities for various setting conditions. The compared results between them show a good agreements.
