摘　　要：平行流换热器因其结构紧凑、换热效率高,被当作冷凝器广泛地应用于汽车空调系统。近年来,又作为蒸发器被应用于家用空调器。但是,平行流蒸发器的冷凝水排除问题限制了其在家用空调器的应用发展和普及。本文针对家用空调器用的平行流蒸发器的冷凝水排除问题进行综合性评述,系统讨论蒸发器材料表面特性、蒸发器布置及导流、蒸发器内通道均流等因素对冷凝水排除的影响。The parallel flow heat exchanger as condenser has been widely applied into the automobile air-conditioning system due to its compact structure and high heat transfer efficiency. Recently, this kind of heat exchanger has also been used as evaporator in room air conditioner. However, it is found that the condensed water in such a case is easily stagnant and weakens the performance of the parallel flow heat exchangers. In this paper, summarizes several main methods to remove the condensed water. In particularly, discusses the influence of the surface property of material, the arrangement of evaporator, cu- rrent sharing on the condensed water removal.
