Zusammenfassung:	The invention provides a Rankine cycle system with a phase change energy storage heat exchanger. The Rankine cycle system comprises an overheating heat exchanger, heat-into-power conversion equipment, a condensation heat exchanger and a pump which are sequentially connected in series. The heat-into-power conversion equipment is connected with an electric generator. The Rankine cycle system further comprises the phase change energy storage heat exchanger and a preheating heat exchanger. One end of the phase change energy storage heat exchanger is connected with one end of the preheating heat exchanger, and the other end of the phase change energy storage heat exchanger is connected with the overheating heat exchanger. The other end of the preheating heat exchanger is connected with the pump. According to the Rankine cycle system provided by the invention, the phase change energy storage heat exchanger is combined with an existing Rankine cycle technology, the small heat transfer temperature difference between
