Abstract�� Basing on numerical optimization principles and thermodynamic performance design, efforts were made to optimize the design of finned-tube lubricate heat exchangers used in helicopters. By taking the weight of the lubricate heat exchangers as an objective function, using the sine method to deal with design constrains, and selecting the simplex accelerated method to search optimization results, optimization design program was developed for the exchangers. An example was given to show that optimum design requirements can be realized by coupling the structure optimization program with the thermodynamic performance design program.
Keywords�� heat exchangers   structure design   optimum design
