Laboratory study and simulation of the effect of geometric changes of the plate heat exchanger in improving its performance.

Plate heat exchangers are one of the new ways of exchanging heat energy between two or more fluids at different temperatures.In this paper the hydraulic and thermal performance of a new design of a plate heat exchanger using simulation and laboratory methods is investigated. In the proposed plate heat exchanger design, first the special geometry including the proposed curved Chevron pattern for the heat transfer zone in the plates is introduced.The results of this proposed plate heat exchanger are evaluated by laboratory method with M6B plate heat exchanger. The simulation and laboratory results show that while maintaining the heat efficiency of the converter, the pressure drop is significantly reduced. This significant reduction in pressure drop of the proposed model leads to a reduction in the number of plates and savings in raw material consumption, reducing the capacity and energy consumed by the pump for fluid transfer, production time and installation space.
