| 摘 要： | 采用红外测温仪测量了液体工质在受热微槽表面的温度场分布,实验研究结果表明:相同深度条件下,较窄的微槽液体工质温度分布较均匀;相同宽度条件下,深度对微槽内液体工质温度分布的影响不大.在较小的热流密度条件下,深度相同时,较窄的微槽汽液界面平均温度较低,宽度相同时,深度的变化对汽液界面平均温度的影响不明显;在较大的热流密度条件下,深度相同时,较窄的微槽汽液界面平均温度较高,宽度相同时,较浅的微槽汽液界面平均温度较高.

| Abstract: | The temperature distribution of vapor-liquid interface on the surface of the microgrooves was surveyed using the infrared thermoviewer.The experimental results show that under the same depths,the narrower microgrooves have the more average temperature distribution;under the same widths,the depth have the small influence on the temperature distribution of working liquid.If the heat flux is smaller,the narrower microgrooves have the lower temperature at the same depth,the depth change is not obvious influence on the temperature of working liquid;if the heat flux is higher,the narrower microgrooves have the higher temperature at the same depth,and the shallower microgrooves have the higher temperature at the same width. |
