| 摘要 |
The invention relates to a heat exchanger system comprising a combustion engine (M) which is cooled via an engine cooling circuit (MK) and to which a medium, especially recirculated exhaust gas and/or charge air, can be delivered. Said heat exchanger system further comprises at least one heat exchanger (AGK; AGK2; ZLLK), particularly an exhaust gas heat exchanger or intermediate charge air radiator, to cool the medium as well as at least one thermostat that limits the minimum temperature of at least one surface of the heat exchanger (AGK2), across which a medium to be cooled or at least one coolant flows, and/or the minimum temperature of the coolant entering the heat exchanger (AGK2; ZLLK), and/or the minimum temperature of the discharged cooled medium, and/or the minimum temperature of the at least partly cooled medium entering a compressor (V2) mounted downstream. The invention also relates to a method for operating such a system. |
