Combined heat exchanger system

Abstract

A combined heat exchanger system includes a first heat exchanger for cooling a first cooling medium, a second heat exchanger for cooling a second cooling medium, and a compressor for compressing the first cooling medium to be supplied to the first heat exchanger. The first heat exchanger is separated from the second heat exchanger, being integrally assembled with the compressor in such a way that the first compressor can be directly and fluidically connected with the compressor. The first heat exchanger liquid-cools the first cooling medium, which is outputted from the compressor, by using the second cooling medium that is cooled by the second heat exchanger.
