Because of high demands for faster and smaller microelectronic systems, effective thermal design for electronic system is a critical issue. A pulsating heat pipe (PHP) is one of the promising solution for modern electronic systems. When a meandering tube is partially filled with a working fluid and a diameter of tube is smaller than certain value, then the effects of surface tension cause the formation of liquid slugs and vapor plugs in a sequence. Then heat can be transported by self-excited pulsating motion. Therefore, the thermal performance of PHP is significantly affected by motion of the working fluid. Previous researchers reported that the thermal performance of a PHP is enhanced by circulating motion of working fluid. However, there is no physical or experimental evidence supporting their assertion. In this study, experiments were performed to investigate the effect of the circulating motion on the thermal characteristics of a micro pulsating heat pipe (MPHP). Silicon-based PHPs were fabricated using MEMS techniques. R-134a was used as a working fluid for PHPs and filling ratio was set to 40%. To figure out flow and thermal characteristics of PHPs, flow visualization was conducted using a high-speed camera. As the size of the diameter of PHPs increases, oscillating motion to circulating motion was observed. Moreover, the thermal performance of PHP is enhanced significantly as fluid motion changes from oscillating motion to circulating motion.
