　　利用阳极氧化法在钛换热管内表面制备出了一层管阵列结构纳米薄膜。以该纳米管阵列表面管为传热元件，蒸馏水为工质，采用管外电加热竖管强制循环工艺，在恒质量流速下考察了纳米管阵列表面管的流动沸腾传热性能。在实验的基础上，得出了纳米管阵列表面管流动沸腾传热系数关联式。实验结果表明，与光滑表面管相比，流动沸腾传热温差降低了30%～55%，在没有增加阻力的情况下，沸腾传热系数提高了1.5～2.2倍。

A nano-film with structure of tube arrays was prepared on the inner surface of titanium tube via anodic oxidization. Taking deionized water as the working fluid,the flow boiling heat transfer properties of the nanoporous surface vertical tube with electrically heated outside surface were studied at constant mass velocity employed by forced circulation. The flow boiling heat transfer coefficient correlation of the tube was obtained. Compared to the smooth tube,the flow boiling heat transfer temperature differences were lowered 30%-55%,and its boiling heat transfer coefficient could be increased 1.5-2.2 times.
