    摘要: This study used numerical simulation to analyze the influence of different factors, such as
    vacuum degree, fill ratio and aspect ratio, on the heat transfer characteristics of low-watt thermosyphon
    in natural convection. The mass and energy source terms were added in the continuity and energy
    equation to simulate the exchanges between vapor and liquid phases. The comparison analysis of
    computed result and experiment data showed that the numerical model used in this study is appropriate
    to analyze the physical mechanism and heat transfer property of thermosyphon. The results confirmed
    that low vacuum degree and long evaporator characterize better thermal resistance. The optimal fill
    ratio was 60% when the vacuum degree was 35 torr and the aspect ratio was 11.8.
