碩士 === 國立高雄應用科技大學 === 機械與精密工程研究所 === 103 === The thesis of a new optimization strategy is applied to the heat exchanger design, mainly with response surface meth and genetic algorithm to explore the relationship between optimal fluid flow velocity and temperature of the heat exchanger. First, finite volume method analysis of the temperature inside the heat exchanger and flow distribution case, and hot and cold water temperature and flow rate of three design parameters utilizing Response surface methodology to identify the most suitable simulation equations, Application of genetic algorithms and then do the best analysis, to find the best number of field synergy, and finally back to the simulation and verification. The results are presented in hot water at 90OC cold water flow rate 0.533 (m /s) to achieve the highest water flow rate of the heat transfer efficiency to 0.1 (m/s), the best results, make reference to the energy-saving design of the heat exchanger.
