摘　　要：通道分配、排列是多股流板翅式换热器设计的关键,并对换热器的性能产生重大影响。如果通道分配、排列不合理,设计出来的换热器同一截面的温差较大,热负荷不平衡,存在大量的热量内耗,使得换热器即使有很大的富裕系数,也无法达到设计指标。并结合实际案例,进行详细对比设计,验证这一结果。Channel allocation, arrangement is more design of plate-fin heat exchanger is the key, and have a significant im- pact on the performance of the heat exchanger. If the channel allocation, unreasonable arrangement, designed heat ex- changer of the same cross section temperature difference is bigger, heat load imbalance, there are a large number of calories consumed, even if there is a lot of rich coefficient makes heat exchanger, also is unable to meet the design index. And combining with actual cases, detailed comparison desizn and verify the results. ＋
