本文对所开发的两种微槽沸腾相变传热管进行了流动沸腾实验研究,考察了强化管对沸腾传热的强化效果和传热性能。实验结果表明,这种结构简单、加工方便、易于应用的强化技术可有效地提高沸腾传热,使核沸腾传热所需的壁面过热度比光管要低得多,EH比SM管低4～5C以上,EC比SM管低10C以上,临界热负荷也显著提高,增强了临界热负荷区的运行稳定性。 In this paper, two kinds of micro-trough boiling phase change heat transfer tubes were developed for the flow boiling experiment, and the strengthening effect and heat transfer performance of the tube on boiling heat transfer were investigated. The experimental results show that this kind of strengthening technology with simple structure, convenient processing and easy application can effectively improve the boiling heat transfer and make the wall superheat required by nucleate boiling heat transfer be much lower than that of the light pipe. The EH is lower than the SM pipe by 4 ~ 5C above, EC is lower than 10C above SM tube, critical heat load is also significantly increased, and enhance the critical heat load zone operating stability.
