摘要
The invention relates to a coolant circuit (1) with an integrated metering module (2) for an auxiliary, in particular for a urea-water solution (HWL), the metering module (2) being arranged on an exhaust pipe (3) of an internal combustion engine (4) and one Has heat sink (5), which is connected to the coolant circuit via an inlet (6) and an outlet (7), so that a coolant of the coolant circuit (1) flows through the heat sink (5) during operation of the internal combustion engine (4), further comprising a heat sink (8) and / or heat source (9) integrated in the coolant circuit. According to the invention, in the installed position of the metering module (2), the outlet (7) of the heat sink (5) is arranged closer to the exhaust pipe (3) than the inlet (6). The invention further relates to a method for cooling an integrated in a coolant circuit (1) Dosing module (2) for an auxiliary.
