웨이비 패턴을 가진 판형 열교환기의 성능에 관한 연구

Abstract

In terms of space-saving, the design of more compact heat exchangers is important. Also, to meet the demand for saving energy and resources today, manufacturers are trying to enhance efficiency and reduce the size and weight of heat exchangers. Over the past decades, there have been tremendous advancements in the manufacturing technology of high-efficiency heat exchangers. This has allowed the use of high-performance heat exchangers. Consequently, those heat exchangers have applied to almost all industries. When compared with the well-established shell & tube heat exchangers, plate heat exchangers show a lot of advantages like high NTU values, compactness, low cost, multi duties, and reduced fouling, etc. To get better thermal performances of plate heat exchangers, a new wavy patterned heat plate was developed through CFD analysis, and it then was experimentally tested to verify the validity of CFD and to compare with a plate heat exchanger with a conventional herringbone pattern. In this study, the development process is introduced, and the results are shared which wavy patterns are better than herringbone patterns.
