Title:
Waste heat recovery device
Document Type and Number:
Japanese Patent JP6298370
Kind Code:
B2
Abstract:
PROBLEM TO BE SOLVED: To provide an exhaust heat recovery system capable of improving exhaust heat recovery efficiency.SOLUTION: An exhaust heat recovery system 100 comprises: a Rankine cycle system 20 using heat of cooling water W from an engine 10 and an EGR cooler 11 as a heat source; and a thermoacoustic cooling device 30 generating an acoustic wave within a thermoacoustic pipe 31 using heat of exhaust gas from the engine 10 as a heat source, thereby causing a cooler-heat exchanger 32a provided in a first normal temperature heat exchanger 32c via a first stack 32b to cool a working medium Q. In the exhaust heat recovery system 100, the thermoacoustic cooling device 30 converts heat energy of the exhaust gas from the engine 10 to cooling energy, and cools the working medium Q of the Rankine cycle system 20 to be able to cool the working medium Q.
