新型板式换热器具有模块化设计、易实现大型化的结构特点以及低压降、防腐蚀的性能优势，在炼油、化工、钢铁、冶金、电力等行业将成为未来的应用主流。但是由于设计完成的换热机产品太大，制作成本高，时间长，不适合用来进行加工试验。所以在其结构基础上，基于相似理论，设计了一个小型的逆流式板式换热器样机及相应的试验台以进行试验。%The new plate heat exchanger with modular design is easy to realize the large-scale. It also has the performance advantage of low pressure drop and anticorrosion. The oil refining, chemical industry, steel and iron, metallurgy, electric power industries will be the future main application of it. But the designed engine for product is too big, the production cost is high, the production time is long, and it does not suit for processing experiment. Based on the above product structure and similarity theory, the paper designs another small type of reflux plate heat exchanger and the corresponding bench for testing.
