Means for cooling a coolant, a circuit for charging an internal combustion engine and method for cooling an intended for charging an internal combustion engine substantially gaseous charging fluid

摘要

The invention relates to a device (1, 2) for cooling a coolant, which is provided for cooling a charging fluid (L) for charging an internal combustion engine, with a refrigerant guide (20), in particular a refrigerant circuit, and a coolant guide (10), in particular one coolant circuit; wherein - the refrigerant guide (20) has a first evaporator (29) for a refrigerant for cooling an ambient air, a second evaporator (19) for a refrigerant for cooling the coolant, - the coolant guide (10) a heat exchanger (11) for the charging fluid (L), a coolant radiator (13), and the second evaporator (19) for the refrigerant of the refrigerant guide (20) for cooling the coolant. According to the invention, in a first variant it is provided that the first and the second evaporator (29, 19) are arranged in the refrigerant guide (20) in a row arrangement. In a second variant it is provided that the first evaporator (29) and the second evaporator (19) in the refrigerant guide (20) are arranged in parallel, in particular where downstream of the second evaporator (19) a suction throttle (35) is arranged downstream of the refrigerant. Preferably, for controlling the capacity of the first and / or second evaporator (29, 19), a refrigerant bypass (30, 31, 33) for the first and / or second evaporator (29, 19).
