This paper introduces the clarifying influence of the intertube spacing, the tube arrangement,the heat flux and the working fluid on boiling heat tra(?)sfer of smooth tube bundles. The tube bundles include the arrangements of twin tubes, triple tubes, seven tubes and thirteen tubes. The relative intertube spacing of the tube bundles is from 0. 9 to 3. 3. Experimental results show that the tube position and intertube spacting have no effect on boiling curves for the region of fully-devoloped boiling. And they considerably affect the heat transfer coefficient for the transition region between natural convection and nucleate boiling. In general,the heat transfer coefficient in the transition region for the upper tubes can be enhanced by 0. 5 to 1. 5 times.

本文实验研究了管束间距、管排数、管束排列方式、热负荷大小和沸腾工质物性等因素对光管管束池沸腾传热的影响规律。实验包括有二排管束、三排管束、七管束、十三管束等,管束相对间距在0.9~3.3之间。实验结果表明,对于旺盛核池沸腾区域,管束中管间距的影响甚微,沸腾曲线基本上与光管时吻合;对于自然对流向核沸腾转折区域,管束各管间的影响较大,明显地使传热强化,一般可提高10~100%。
