| 摘 要： | 本文应用界面化学理论研究表面作用对分离式热管小螺旋管蒸发段管内流动和换热特性的影响。通过实验及分析，提出通过在一定范围内提高热管工作温度和添加润湿剂以降低水的表面张九提高管内壁的粗糙度以增强液膜的铺展性能。利用这两种方法可以有效地增强小螺旋管内壁面的润湿性能，从而提高管内换热性能．

| Abstract: | The Influence of surface effects on flow and heat transfer inside small helical coiled tubes of evaporator of separate type heat pipe was studied using theory of interface chemistry. Surface tension can be reduced through increasing working temperature of heat pipe over a suitable range and applying wetting agent; expansive performance of liquid film can be improved through increased roughness of coiled tube's inside wall. Wetting capability of wall was advanced using this two ways, therefore, performance of heat transfer was enhanced. |
