Optimization Design of a New Safety Structure of Plate-Fin Heat Exchanger Using Genetic Algorithm

Abstract:

A safety structure of plate-fin heat exchanger is designed for some special applications to avoid fluid leakage from one fluid side to the other fluid side. A cavity is designed between two channels and a part of cavity volume is filled with good-thermal conductivity material which is divided into a number of columns. For better thermal performance of this structure, distribution of these columns is optimized. Genetic algorithm is used in optimization of distributions, it is effective and the output is better than the simple optimization. The structure in this paper can provide a new feasible structure of secure plate-fin heat exchanger, and the optimization results obtained by using genetic algorithm can provide some guidelines for the optimal designs of heat exchangers.
