Title:
RANKINE CYCLE DEVICE
Document Type and Number:
Japanese Patent JP2020098067
Kind Code:
A
Abstract:
To provide a Rankine cycle device advantageous for improvement of reliability and durability.SOLUTION: A Rankine cycle device (10a) includes an evaporator (2), an expander (3), a condenser (4) and a pump (1). The evaporator (2) includes a plurality of heat exchangers disposed in a heating medium flowing direction. The plurality of the heat exchangers include a first heat exchanger (2a) and a second heat exchanger (2b). The first heat exchanger (2a) is a heat exchanger to which a working fluid is caused to flow in first in the evaporator (2). The second heat exchanger (2b) is a heat exchanger to which the working fluid that has passed through the first heat exchanger (2a) is caused to flow in. Corrosion resistance of a surface coming into contact with a heating medium of a member defining a flow passage of the working fluid in the first heat exchanger (2a) is higher than that of a surface coming into contact with the heating medium of a member defining a flow passage of the working fluid in the second heat exchanger (2b).SELECTED DRAWING: Figure 1
