多管式换热器的研究及工业应用分析

多管式换热器是一种较为新型的高效换热器，目前对于这种换热器的研究较少，其传热性能的研究也鲜见报道。对多管式换热器做了初步的研究，并以实际工业装置工况为例，采用管壳式、多管换热器和翅片管多管式作为换热器设计的三种方案，利用HTRI软件进行模拟，比较出三个方案在传热和经济方面的性能差异，分析多管式换热器在工业应用中优势，为研究和推广这种新型的换热器提供有价值的参考依据。

Research of Heat Exchanger with Multi Type Tubes and Its Application in Industry

The heat exchanger with multi type tubes is one new high efficiency heat exchanger.Currently,there is rare research focused on this king exchanger,and there is a less reported research on the feature of heat transfer for this exchanger.In this article, the primary research for this exchanger was carried out.With practical conditions in industrial constructions,tubular,multi type tubes and fin tube heat exchangers were compared in the properties of heat transfer and economy by using software HTRI.The pros of multi type tubes exchanger in industrial application were analyzed,by which references for the research and spreading of this kind of exchanger are provided.
