In this study, We disigned and manufactured the Hot Chuck which can be operated until $120^{\circ}C$. Its shape is circular, wide is 300mm and depth is 15mm. Two types working fluid was used as working fluid(distilled water, 0.1%-$TiO_2$ nanofluid). The experimental results were compared to each working fluid. The effect of various working fluid, charging volume ratio was investigated. Also we investigated heat transfer rate against each working fluid. By using nanofluid, heat transfer rate can be enhanced and the wick structure can be constructed automatically on smooth surface. The experiment of 40% charged 0.1%-$TiO_2$ nanofluid showed the best performance of thermal accuracy and uniformity. To improve performance of Hot Chuck, more study is needed.
