鉛直に配置した長尺ヒートパイプの動作特性に対する充填率の影響

抄録

This paper presents effect of filling ratio on the transient and steady thermal performance for a long vertical heat pipe. This heat pipe consists of three sections: cooling section, heating section and sub-heating section. Sub heating section helps to increase the flow volume of working fluids and prevents lack of it in heating section during start-up. The experimental results show increasing fill ratio causes cyclic temperature variation in steady and transient performance and prevents temperature overshoot in transient performance.
