Simulation and calculation of modular integrated design of heat exchanger

The modular integrated design of the five heat exchangers of the air-conditioning system, auxiliary cooling system and air quasi-system in the aircraft environmental control system resulted in four plans: comprehensive plan 1, comprehensive plan 2, comprehensive plan 3, and comprehensive plan 4; Use MATLAB/Simulink to simulate and model the ram air system components including heat exchangers and build a ram air full-channel simulation platform; Build a single-channel heat exchanger test platform to verify the validity and correctness of the simulation platform;The simulation platform is used to calculate the performance of the full envelope of the four plans.
