考虑制造约束的印刷电路板式换热器优化设计

Aiming at the integrated design and manufacturing of micro-channel structure parameters for printed circuit heat exchanger (PCHE), the performance optimization research of heat exchangers considering manufacturing constraints is carried out. Through fluid simulation, the influence of flow channel width, depth, and aspect ratio on temperature distribution, pressure loss, and heat transfer coefficient is analyzed. A multi-objective genetic algorithm (MOGA) is used to establish a multi-variable and multi-objective optimization simulation model for heat transfer performance. The results of the performance simulation are used to establish the microchannel structure rolling forming process, and the manufacturing constraints are obtained. The manufacturing constraints are fed back to the performance optimization simulation model. Consequently, the microchannel design parameters with a width of 0.29 mm and a depth of 0.39 mm are obtained, and the feasibility of the optimization method was verified by the roll-to-roll (R2R) process test. The designed method of heat-exchanger optimization considering manufacturing constraints introduce process constraints in the stage of performance optimization design, and is proved an effective measure to achieve the integrated design and manufacture of heat exchangers.
