Abstract
In this study, the performance of plate heat exchanger with snake pattern that is expected to occur more turbulent than the conventional herringbone pattern was investigated.

Generally, there are three kinds of plate heat exchanger types, H, M, L. H type consists of heat transfer plate with 120° chevron angle, L type with 60°and M is a mixed type with H and L types.

First, computational fluid dynamics(CFD) analysis were used to predict the heat transfer and pressure drop characteristics of each plate heat exchanger with snake and herringbone patterns, and then experiments were carried out to find out performance data of H, L M-type. Finally, the performance of plate heat exchangers with snake pattern was compared with that of the conventional plate heat exchangers with herringbone pattern.

The heat transfer performance of snake pattern is about 10% higher than
