强化管材质的导热系数对膜状凝结传热过程具有重要的影响,本文通过实验对比了铝黄铜和白铜两种材料制成的三维高效管和低肋管的凝结传热特性.结果表明对于同种材质的强化管,三维高效管比低肋管强化效果好;当强化管类型相同时,较低导热系数管冷凝管传热系数较低,即铝黄铜的凝结传热强化效果优于白铜。 The heat transfer coefficient of the strengthened pipe material has an important influence on the film condensation heat transfer process. In this paper, the condensation heat transfer characteristics of the three-dimensional high-efficiency pipe and the low-cost pipe made of aluminum brass and white copper are compared by experiments. The same material of the enhanced tube, three-dimensional high-efficiency tube than the low-cost tube to enhance the effect is good; when the same type of tube, the lower thermal conductivity of the tube heat transfer coefficient is lower, that aluminum, aluminum condensation heat transfer enhancement is better than White copper.
