| 中文摘要: |
| 围绕径向热管的等温性能，对无吸液芯径向热管的外管壁面和内管壁面的温度特性进行了实验研究，分析了不同充液率和不同控制温度下，无吸液芯径向热管管壁的温度分布以及径向热管的换热机理。通过实验研究发现，径向热管轴向不仅具有良好的等温性能而且具有良好的温度稳定性；由于热管本身比较大的等效热容，使得径向热管对温度波动具有明显的衰减作用。 |
| 英文摘要: |
| Radialheat pipe has more advantages than axial heat pipe in terms of isothermal. This paper presents an experimental investigation of the radial heat pipe behaviors in isothermal characteristics. In this paper, the heat transfer mechanism of radial heat pipe is analyzed under different controlled temperature and different fill ratios. The results show that radial heat pipe not only has good isothermal performance, but also has good temperature stability. Moreover，the radial heat pipe has a damping effect on the temperature fluctuations because of its equivalent heat capacity. |
