DEVICE AND METHOD FOR COOLING AN EXHAUST GAS AFTERTREATMENT APPARATUS

The present disclosure relates to a method and a device (10) for cooling an exhaust-gas after-treatment apparatus (12). The device (10) has a coolant circuit (16) with a cooling region (18) for heat transfer with the exhaust-gas aftertreatment apparatus (12) and has at least one backflow preventer (...

Beschreibung
Zusammenfassung:	The present disclosure relates to a method and a device (10) for cooling an exhaust-gas after-treatment apparatus (12). The device (10) has a coolant circuit (16) with a cooling region (18) for heat transfer with the exhaust-gas aftertreatment apparatus (12) and has at least one backflow preventer (20, 22). The at least one backflow preventer (20, 22) is arranged upstream and/or downstream of the cooling region (18) and is configured and/or oriented such that, in the event of a change in volume of the coolant in the cooling region (18) and in a section of the coolant circuit (16) between the cooling region (18) and the at least one backflow preventer (20, 22), said at least one backflow preventer (20, 22) opens, which takes place below a boiling point of the coolant. A natural circulation of the coolant in the coolant circuit (16) below the boiling point of the coolant can thus preferably be provided.
