Characteristics of heat transfer and resistance of double chevron plate heat exchanges with different corrugation pitch

Abstract

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. © 2012 Springer-Verlag GmbH.
