Abstract: The present disclosure provides a method for designing a supercritical heat exchanger based on pseudo-phase transition partition. The method mainly includes the following steps: inputting boundary conditions of a heat exchanger; calculating an upper boundary temperature and a lower boundary temperature of a pseudo-phase transition region; calculating a temperature of an inner wall surface of a supercritical fluid; determining an upper boundary temperature of a pseudo-superheated condensation region; and dividing the heat exchanger into four sections on the basis of above three boundary temperatures and inlet and outlet temperatures, and calculating the section size and the total size of the heat exchanger. According to the method, the automatic partition determination of single-phase cooling and pseudo-superheated condensation in a supercritical air cooler can be realized, requiring no division of the heat exchanger according to equal enthalpy change or equal length, and the calculation is rapid and accurate.
