摘要： 将“分液冷凝”强化传热应用于板式冷凝器, 建立了多流程分液板式冷凝器的物理和数学模型, 采用性能评价参数(η)比较了相同传热面积的4种结构板式冷凝器(普通型、两流程、三流程和四流程)的热力性能。结果表明：流程数越多, 分液板式冷凝器的综合性能越好, 其η最高, 为1.12。普通型板式冷凝器后一流程的传热系数比前一流程要低, 而分液冷凝器与之相反。在相同工况下, 分液冷凝器的热负荷与出口干度均高于普通型板式冷凝器。

Abstract: In this paper, the liquid-separation condensation, which is a heat transfer enhancement technology, is applied to the plate condenser. The physical and mathematical models of the liquid-separation plate condenser with multi-path are established. The thermal performance of four plate condensers (conventional type, two-path, three-path and four-path) having the same heat transfer area is compared by using performance evaluation parameters (η). The results show that the performance of liquid-separation plate condenser increases with the path numbers. The η can reach up to 1.12. In the conventional plate condenser, the heat transfer coefficient in the later path is lower than that in the previous path, whereas it is opposite in the liquid-separation plate condenser. Under the same working condition, the heat load and vapor quality at the outlet of liquid-separation plate condenser are higher than these of the conventional plate condenser.

Key words: liquid-vapor separation plate condenser, multi-path, performance evaluation parameters, heat transfer coefficient
