Characteristics Analysis of Double Chevron-Type Plate Heat Exchanges with Different Corrugation Ratios

The thermal and hydraulic performances of working fluid in three corrugated channels have been investigated, numerically by a three-dimensional model with a new-type corrugation Plate Heat Exchanger (PHE)—double chevron-type PHE (DCPHE). The heat transfer character, the flow resistance and the Performance Evaluation Criteria (PEC) of the working fluid in double chevron-type PHE have been discussed; Results showed that the double chevron-type PHE with 2:1 of corrugation ratio was better one
