An efficient and accurate method for optimizing capsule-type plate heat exchangers is proposed in this paper. This method combines computational fluid dynamics simulation, a backpropagation algorithm and multi-objective optimization to obtain better heat transfer performance of heat exchanger structures. For plate heat exchangers, the heat transfer coefficient j and friction coefficient f are a pair of contradictory objectives. The optimization of capsule-type plate heat exchangers is a multi-objective optimization problem. In this paper, a backpropagation neural network was used to construct an approximate model. The plate shape was optimized by a multi-objective genetic algorithm. The optimized capsule-type plate heat exchanger has lower flow resistance and higher heat exchange efficiency. After optimization, the heat transfer coefficient is increased by 8.3% and the friction coefficient is decreased by 14.3%, and the heat transfer effect is obviously improved. Further, analysis of flow field characteristics through field co-ordination theory provides guidance for the further optimization of plates.

“…There are works concerning new ways to combine local heat transfer measurements and flow visualization using an FPHE simultaneously, obtaining viable solutions to obtain local heat transfer with a flow regime without a plate channel, preserving real geometry and operating condition [4]. Unprecedented cross-corrugated plate characterizations have been performed for aero-thermal performance for aerospace engine cycles, using a transient liquid crystal heat transfer (TLC) technique, with Reynolds 1300 to 13000, resulting in new Nusselt and Prandtl correlations for future plate heat exchanger optimizations [5], [6]. They have also conducted experimental comparative studies for sealed plate heat exchangers using three different plates, based on Reynolds numbers between 300-5000 and Prandtl numbers depending on Chevron's angle, correlations were obtained for each plate, deriving for the number of Nusselt and the friction factor [7].…”

The way to evaluate a device in charge of heat transfer under certain working conditions is through the study of the global coefficient of heat transfer, it was carried out using a test bench that includes the base unit where the heating and movement of water is carried out and a unit where the heat exchange is carried out connected by means of flexible tubes and using the fundamental equations that are required, the results obtained were respectively the global transfer coefficient for both fluids of work with their respective Nusselt number, finally it is observed that the relationships between other models for plate exchangers, the comparative error is very large (40%) and to have more concise results. the scale factor must be taken into account.
