Based on the design and calculation of the initial thermal performance of the helicopter fin tube oil heat exchanger, the optimization design of the structure of the oil heat exchanger was studied by applying the numerical optimization principle and the structure optimization procedure was established. The weight of the heatsink is the objective function, which is controlled by the sine method and optimized by the simplex acceleration method.Examples show that combining the thermal performance calculation program of the oil heat exchanger with the structure optimization program can create an automatic matching exchange The design and optimization of the heater system.Using the software, enter the design requirements, can meet both the performance requirements, and the lightest weight of the tube-type oil cooler heat exchanger.The software can be widely used in various types of ribbed tube Heat Exchanger .
