The hydraulic diameter influenced the heat transfer performance of the wavy channel, and the heat flux increased when the flow direction changes. The pressure variation of air had a limited effect on PCHE heat transfer. The tempera- ture distributions of the cold and hot fluids were almost the same for the four-stage intercooled heat exchanger, but the flow resistance distribution showed a great differ- ence; a higher air pressure led to a smaller flow resistance. The incline angle had a significant effect on heat transfer and flow resistance. The best performance in terms of heat transfer and resistance was realized when the bending angle was 15◦ in this study.
