沸騰気泡駆動型ヒートパイプ BACH の熱輸送モデル検討

抄録

Bubble-actuated circulating heat pipe, BACH, is one of new types of heat pipe, utilizing buoyancy force of vapor bubbles generated at bubble-generation part for liquid circulation. In the former report, top-heat BACH consisting of heated section, cooled section and intermediate cooled section were presented. The bubble buoyancy force acts only at between the heated section and the intermediate cooled section, realizing liquid circulation for heat transport from the heated section to the cooled section. The heat transport model of the topheat BACH was proposed in the former report which show that heat transport rate of top-heat BACH is affected by several parameters. However, there were several problems to solve in order to establish general heat transport modeling of BACH. In this report, the authors proposed methods to solve these problems.
