Characteristics of Heat Transfer and Resistance of Double Chevron Plate Heat Exchanges with Different Corrugation Pitch

A mathematical model is developed in algorithmic form for the steady-state simulation of plate heat exchangers with generalized configurations. In present works, 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 PHE (DCPHE). The heat transfer character, the flow resistance and the Performance Evaluation Criteria (PEC) of the working fluid in double chevron PHE have been discussed; Results showed that the double chevron PHE with 9mm of corrugation pitch was better one.
