Waste heat recovery arrangement of a motor vehicle and method for using waste heat in a waste heat recovery arrangement

摘要

The invention relates to a waste heat utilization arrangement (1 to 1 ') for utilizing waste heat of an internal combustion engine (4) in a working medium circuit (3) of a waste heat recovery device (1.2), characterized in that - in a coolant circuit (2) of the internal combustion engine (4) Internal combustion engine (4) a conveyor (5.1) and downstream of at least a first heat exchanger (6) are arranged which cools a waste heat in a line (8) waste heat stream (AS) and the heat of the exhaust stream (AS) to a coolant (KM) the coolant circuit (2) transmits, and that - in the coolant circuit (2) the first heat exchanger (6) a second heat exchanger (7) is connected downstream, the heat of the coolant (KM) to a working fluid (AF) in the working medium circuit (3) transfers, so that the working medium (AF) in the working medium circuit (3) at least partially evaporated, and that - the Arbeitsmedi Circulation (3) is designed as a steam power process, the at least the output side of the second heat exchanger (7) has an expander (9) and this downstream of an air-cooled condenser (10).
