Abstract:
1. A device for utilizing waste heat of an internal combustion engine, comprising: a heat exchanger of a circuit of a working medium situated in an exhaust system of the internal combustion engine, the circuit including an expansion machine; a pump connected upstream from the heat exchanger; and a coupling heat exchanger situated in the circuit of the working medium, the working medium of the circuit and a cooling medium of the internal combustion engine flowing through the coupling heat exchanger; wherein at least one flow out of the coupling heat exchanger is selectively fed into a connecting line which is connected to the internal combustion engine in a warm-up phase of the internal combustion engine preceding reaching of a normal operating temperature of the internal combustion engine, and wherein the at least one flow out of the coupling heat exchanger is selectively fed into a radiator inlet of a radiator when the internal combustion engine is operating at the normal operating temperature.
