Abstract
A heat exchanger arrangement is provided for an internal-combustion engine having a heat engine, which converts hot steam of a working medium by way of an expansion device to kinetic energy. The working medium, that can be delivered by a pump, can be heated in a first heat exchanger by a coolant and in a second heat exchanger by an exhaust gas of the internal-combustion engine. In the delivery direction, the working medium first flows through the first heat exchanger and, subsequently, through the second heat exchanger. The exhaust gas can flow through the first heat exchanger.
