| 摘 要： | 对水－甲醇混合工质两相闭式热虹吸管的传热特性进行了实验研究，实验表明，水－甲醇混合工质热管与纯工质（水）热管之间，以及在不同倾角条件下，热管轴向壁温分布均有较大差别，这是由于甲醇（易挥发组分）轴向浓度分布不同造成的。

| Abstract: | The heat transfer characteristics of a closed two-phase thermosiphon at different incline angles are experimentally investigated. The working fluid is a mixture of methanol and water with different ratios. The axial temperature distribution at the heating wall is much different from that in the case of one-component (water) working fluid. There is also a difference between heat pipes working with different mixture ratios. This is due to the axial distribution of methanol concentration. |
