A device for cooling a coolant, for cooling a charging fluid for charging an internal combustion engine is provided that includes a refrigerant guide, particularly a refrigerant circuit, and a coolant guide, particularly a coolant circuit; wherein the refrigerant guide comprises a first evaporator for a refrigerant for cooling an ambient air and a second evaporator for a refrigerant for cooling the coolant, the coolant guide comprises a heat exchanger for the charging fluid, a coolant cooler, and the second evaporator for the refrigerant of the refrigerant guide for cooling the coolant. In a first variant, the first and the second evaporator are disposed in series in the refrigerant guide. In a second variant, the first evaporator and the second evaporator are disposed in parallel in the refrigerant guide, particularly wherein a suction throttle is disposed downstream in the refrigerant flow after the second evaporator. A refrigerant bypass for the first and/or second evaporator serves for controlling the performance of the first and/or second evaporator. |
