摘要： 提出一种新型的蒸发器，在平行流的联箱中设计带分液小孔的隔板，利用其气液分离作用对蒸发区的制冷剂干度进行调控.建立了分液蒸发器的计算模型，并进行实验验证，结果表明传热系数和压降的偏差在±30%以内.分析了不同管程分布对分液蒸发器性能的影响，结果表明管程对性能的影响较大.

关键词: 分液蒸发器, 管程分布, 传热系数, 压降

Abstract: A novel evaporator with a vapor-liquid separation is proposed. It can control quality of refrigerants by vapor-liquid separation that is accomplished by the baffle with small holes in the heads. A steady model of the vapor-liquid separation evaporator is established. The calculated heat transfer coefficient and pressure drop are verified by experiments with errors within ±30%. The effect of tube arrangements on the thermodynamic performance of the evaporator is analyzed by this program. The results show that the effect is significant.

Key words: vapor-liquid separation evaporator, tube pass scheme, heat transfer coefficient, pressure drop
