摘　　要：结合传统的管壳式换热器设计加工出一个冷凝器,冷凝器管箱两端的隔板上开有分液小孔,并通过设计搭建的凝结换热实验台,对冷凝器的换热特性进行了实验研究。通过对实验结果的归纳,结果表明凝结液封稳定的情况下,凝结换热系数随开启漏液管数增加而变大。这是对以后设计高效换热器进行的有益探索。Based on the design of the traditional tube and shell heat exchanger, a condensor was fabricated and a hole on the clapboard at the ends of condensor was punched. The results show that condensation heat transfer coefficient is larger with the in- crease of number of discharge tube under the condensation liquid seal stability. This is beneficial exploration for high - efficiency heat exchanger design in the future.
