蒸发

In order to improve the performance of high temperature thermosiphon, it is suggested that coaxial tube insert be employed in the evaporator to form natural flow boiling in an annular gap.

带内插管高温热虹吸管的研究。提出在高温热虹吸管蒸发段插入同心管形成环隙内的自然流动沸腾以改善高温热虹吸管的性能。

And, theoretical and experimental studies have been carried out of the performance of the heat transfer enhancement by adding a proper amount of nanoparticles to the thermosiphon with water as the working fluid. Compared with the ordinary thermosiphon, results indicate that this heat pipes posses such advantages as good startup, lower tube wall temperature, and its heat transfer coefficient is increased by 47～96%, heat flux is increased by 7.6～15% in the range of the experiment. The performance of the heat transfer relates to the diameter and the volume fraction of nanoparticle.

理论和实验的研究了这种热虹吸管蒸发段的工作特性，结果表明，与普通热管相比较，这种新式热管具有很好的启动特性，低的管壁温度，换热系数提高了47～96％，轴相热流率提高了7.6～15％，其换热性能随纳米颗粒粒径的减小而增大，随纳米颗粒加入量有所增加，当超过一定量时换热性能反而降低了。
