Heat exchange optimization method for wing type heat exchanger

The invention discloses a heat exchange optimization method for a wing type heat exchanger, and the method comprises the steps: taking S-CO2 as a flowing working medium, selecting key geometric parameters La, Lb and b which influence the flowing heat exchange characteristics of the heat exchanger as optimization parameters, and taking maximization deltaQ/deltaP and Nu/Eu as optimization targets; setting an action space based on the optimization parameter change, optimizing the heat exchanger by using an agent model through a manual parameter value adjustment simulation analysis method, and comparing the thermal hydraulic characteristics of the obtained heat exchanger with the original heat exchanger design; and establishing a reward function consistent with the optimization target, and comparing and analyzing the thermal-hydraulic characteristics of the heat exchanger optimized by adopting the DQN algorithm with the design of the original heat exchanger and the design of the heat exchanger obtained by manual
