Abstract：According to the design requirement of decreasing the volume and material uses, corresponding object function was established. Genetic algorithm was used to optimize the structure of radiator, including the wave hight and distance of the corrugated fin, length and width of the water pipe cross section, and core width as the decision variables. By studying the characteristics of optimization course, population initialization, selection operator and mutation operator of simple genetic algorithms were modified. Optimal design software was developed so as to verify the correctness of optimal model and modified genetic algorithms. Optimal example showed that the heat transfer area was reduced by 31.2% after optimization. So this modified method can obtain a better optimal effect on the radiator structure optimization.
