Abstract :
This study utilizes a silver nano-fluid on a flat heat pipe. It studies the effect of various concentrations on flat heat pipe thermal performance by air-cooling testing equipment. The particles used in these experiments were silver particles 35 nm in size. The base working fluid was pure-water. Nano- fluids were prepared using a two-step method. In the experiment, the thickness and length of the heat pipe are 3 mm and 200 cm, respectively. An experimental system was set up to measure the temperature distribution of heat pipes and calculate the thermal resistance by equation R = DeltaT IQ. At the same charge volume, the thermal resistance of the heat pipe filled with nano-fluid was lower than that of DI water.
