<P>PROBLEM TO BE SOLVED: To avoid decrease in efficiency of waste heat recovery while reducing warm-up time of a heat engine. <P>SOLUTION: A rankine cycle circuit 13 comprises an expander 31, a heat exchanger 47, a condenser 49, a pump 41, and a boiler 42. A high temperature and high pressure cooling medium heated by the boiler 42 is introduced into the expander 31 via a supply flow path 46. A heat exchanger 47 is provided downstream of the expander 31. The condenser 49 is provided downstream of the heat exchanger 47. The low-pressure cooling medium expanded by the expander 31 is sent to the condenser 49 via the heat exchanger 47. The heat exchanger 47 comprises a heat dissipation part 471 and a heat absorption part 472. A discharge flow path 48 and a connection flow path 50 are connected via the heat dissipation part 471. A heat absorption part 422 is provided at a branch flow path 521 of a cooling water circulation passage 52 connected to an engine 12. <P>COPYRIGHT: (C)2013,JPO&INPIT |
