    • Effects of a Secondary Wick on the Thermal Performance of a Loop Heat Pipe 

      Taketani, Masahiko; Nagai, Hiroki (44th International Conference on Environmental Systems, 2014-07-13)
      A Loop Heat Pipe (LHP) is a heat transfer device utilizing the phase change of fluid. It has high heat transfer performance and robustness to changes in the ambient temperature. However, LHPs have problematic startup ...
    • Mathematical Modeling and Experimental Validation of Oscillating Heat Pipes 

      Daimaru, Takurou; Yoshida, Shuhei; Nagai, Hiroki; Okamoto, Atsushi; Ando, Makiko; Sugita, Hiroyuki (44th International Conference on Environmental Systems, 2014-07-13)
      This paper is intended to investigate the startup behavior of Oscillating Heat Pipes (OHPs). First, a mathematical model of OHPs is presented. The model is a one-dimensional slug flow model in which the movement of liquid ...
    • Operation Characteristics of Loop Heat Pipes with PTEF and SUS wicks 

      Okazaki, Shun; Ogawa, Hiroyuki; Nagano, Hosei; Nagai, Hiroki (44th International Conference on Environmental Systems, 2014-07-13)
      A loop heat pipe (LHP) is a two-phase heat transfer device. Recently, small LHPs on the order of a few hundred watts have been investigated. We have developed a new primary wick made of stainless steel (SUS). In this study, ...
    • Visualization of Loop Heat Pipe with Multiple Evaporators under Microgravity 

      Matsuda, Yuta; Nagano, Hosei; Okazaki, Shun; Ogawa, Hiroyuki; Nagai, Hiroki (45th International Conference on Environmental Systems, 2015-07-12)
      In this paper, a loop heat pipe with multiple evaporators (MLHP) whose evaporators and a condenser can be visualized was newly designed, fabricated. The inside of a wick core and a compensation chamber were observed by ...
