To minimize the temperature of propulsion motor and reduce flow loss in water-cooling structure during operation an underwater unmanned vehicle, this paper employs a multi-objective genetic algorithm to optimize dimensions inner outer dual-channel as well rate cooling water. Firstly, influence design variables on response was examined through sensitivity analysis. Subsequently, model sample library for simulating coupled fields constructed, surface between developed. Finally, appropriate points were selected from Pareto solution set verify validity optimization results CFD simulation error The analysis indicate that water had greatest impact both maximum losses structure, with values 77.79% 99.84%, respectively. On other hand, optimal parameters four channel obtained. Compared initial decreased 332.86 K 331.46 K. Simultaneously, 100.02 kPa 59.58 kPa, reduction 40.43%. effect system is significant, which provides valuable insights under premise ignoring interactions.
