Title:
WASTE HEAT COLLECTOR
Document Type and Number:
Japanese Patent JP2019090397
Kind Code:
A
Abstract:
To suppress the enlargement of a size of a waste heat collector in which a working medium is heated by the waste heat of an engine via a heat input medium.SOLUTION: A waste heat collector 25 comprises: a first circulation circuit 31 in which a heat input medium flows; a first pressure-sending machine 32 for making the heat input medium circulate to the first circulation circuit 31 by pressure-sending the heat input medium; a first heat exchanger 35 and a second heat exchanger 37 for raising a temperature of the heat input medium by exchanging heat with an exhaust gas; a second circulation circuit 41 in which a working medium flows; a second pressure-sending machine 42 for making the working medium flow to the second circulation circuit 41 by pressure-sending the working medium; an evaporator 44 for evaporating the working medium by exchanging heat with the temperature-raised heat input medium and the working medium which is pressure-sent by the second pressure-sending machine 42; an expander 46 which operates by the passage of the evaporated working medium; and a condenser 48 for condensing the working medium which has passed the expander 46. Both a drive shaft of the first pressure-sending machine 32 and a drive shaft of the second pressure-sending machine 42 are set as driven shafts which follow an output shaft of a common motor.SELECTED DRAWING: Figure 1
