The factor of equipartition of entransy dissipation was defined at first, and then, applying three-dimensional CFD software-ANSYS CFX, the double chevron-type plate heat exchangers (DCPHE) were simulated, and the entransy loss rate, the exergy loss rate and the equipartition of entransy dissipation (EoED) of the working fluid in DCPHE with five corrugation angles were investigated. Results from numerical simulations showed that the exergy loss rate of the working fluid in DCPHE with β=30° were lower than those under same mass flow conditions; the entransy loss rate of the working fluid in DCPHE with β=30° were lower than those under same amount of heat conditions; the factor of EoED of the working fluid in DCPHE with β=30° were more than those under same number of transfer units (NTU) and effectiveness conditions.
