多股流板翅式换热器根据需要布置成不同的通道排列形式,可由一股或几股冷(热)流体同时冷却(加热)其他一股或几股热(冷)流体,从而起到多台两股流换热器或换热网络的作用。多股流板翅式换热器换通道分配、排列是否合理,直接决定着板翅式换热器的性能与经济指标。近年来,对板翅式换热器的研究主要集中在翅片结构尺寸及翅片的形式,对换热通道的研究甚少。Aspen Plus是一个生产装置设计、稳态模拟和优化的大型通用流程模拟系 Multi-flow fin-and-plate heat exchangers are arranged in different channel arrangements according to the needs, and one or more cold (hot) fluids can cool (heat) one or more other hot (cold) fluids at the same time, More than two stream heat exchangers or heat exchange network role. Multi-stream plate fin heat exchanger for passage distribution, arrangement is reasonable, directly determines the performance of plate-fin heat exchanger and economic indicators. In recent years, the research on the plate-fin heat exchanger mainly concentrates on the fin structure size and the form of the fin, and there is little research on the heat transfer channel. Aspen Plus is a large, general-purpose process simulation system for plant design, steady-state simulation and optimization
