| 摘 要： | 1引言行化行业大量的立、卧式重沸器等中都涉及沸腾相变传热。超大规模集成电路的正常工作需要具有10’W／m’量级甚至更高的散热能力山，航天热环境控制也同样要求在小温差下具有极高的散热强度问。对于这些高热流、低温差传热问题，往往也采用沸腾相变的方法解决。沸腾强化技术研究有很长历史，已发展出许多有效的方法，Thome问对过去数十年的工作做了系统的综述。具有烧结多孔表面薄展的HIGHFLUX管则，机加工扩展表面的THERMOEXEC－E管问，西德研制的GEWA－T管问，虽然在强化池沸腾时具有优异性能，很少用于强化流动沸腾。在…

| Abstract: | An experimental investigation was conducted to identify the heat transfer performanceof liquld flow boiling through microchanneled tubes. Compared with smooth tube, the flowboiling heat transfer in enhanced tubes is apparently intensified, and the wall superheat ofboiling initiation is significantly decreased. For the case of small flow rate, the boiling heattransfer coefficient of enhanced tube is 1.7 times higher than that of smooth tube. |

| Keywords: | flow boiling heat transfer enhanced tube microchanneled surface |
