摘　　要：针对"氮侧一程、氧侧三层加长板式主冷凝器"结构,得出氮侧一程由上至下的液化饱和压力、饱和温度连续降低。结果是对应氧一层至氧三层传热能力,包括:传热温差Δt积分、传热系数K、传热负荷Q依次下降。最终达不到设计参数条件下总传热负荷要求。This article contrapose the structure of＂nitrogen-side-one-route and oxygen-side-three-layers extension plate-fin main condenser＂,get the results that the liquefaction saturation pressure and saturation temperature consecutive decrease in nitrogen-side-one-route from top to bottom. This leads to the result that the heat-transfer capability which includes the heattransfer temperature difference Δtinte,the heat-transfer coefficient K and the heat-transfer load Q decline from the first layer to the third layer of oxygen side. Finally the total heat-transfer load can not meet the demand under the design condition.
