| 摘 要： | 通过实验对三维管换热元件与传统H型鳍片管进行测试，研究其传热特性. 结果表明，三维管换热器的总换热系数是H型鳍片管换热器的2?3倍，采用错列布置换热管比顺列布置换热管的阻力大. 修正的气侧对流换热系数关联式更符合实际，计算结果比原式提高约26%，FLUENT软件能很好模拟三维管换热器的实际情况，模拟结果误差较小.

| Abstract: | A comprehensive and detailed test had been performed for three-dimensional tube exchange components and traditional H-type fin tube through a prototype to investigated their heat transfer characterization. The results showed that the total heat transfer coefficient of the three-dimensional tube heat exchanger is 2 to 3 times that of the H-type fin tube heat exchanger, and the resistance of the heat exchanger in staggered arrangement was bigger than that of in-line arrangement. Besides, the modified correlation of gas side convective heat transfer was more realistic, and the calculated result is about 26% higher than that of the original correlation. FLUENT software can simulate the actual situation of three-dimensional tube heat exchanger, and the simulation results error is relatively small. |
