Abstract

A cooling arrangement for cooling charge air of a supercharged internal combustion engine. In a charge-air line that leads to the internal combustion engine, there are provided a compressor arrangement, which has at least one compressor stage, and an expansion arrangement, which has at least one expansion stage for lowering the pressure level and thus for cooling the charge air. A cooling device is provided between the compressor arrangement and the expansion arrangement. The at least one compressor stage and the at least one expansion stage are connected in series and are respectively connected in terms of drive to an electric motor. The compressor arrangement has at least two compressor stages connected in parallel.
