Abstract

Bubble jet loop heat pipe is what heat pipe operate in the horizontality. It is consist of one heating part creating bubble and one rounded U tube type radiator. This study shows whether the heat pipe operates well in the horizontality or not, and what optimized refrigerant charging rate is in the tube. But flow visualization of bubble jet heat pipe was not known. The purpose of this study is to visualize bubble jet loop heat pipe. The experiment was performed by changes of charging rate. Working fluid was R-141b. And heater of 220 V & 100 W was used. we take a photograph of flow visualization of bubble jet loop heat pipe in slow motion.
