Device for cooling dosing module, particularly for feeding reducing agent into exhaust tract of internal combustion engine, comprises dosing module, which is assigned cooling unit, by which coolant is flowed through

摘要

The device comprises a dosing module (10), which is assigned a cooling unit, by which a coolant is flowed through, and a lateral surface (12) of the dosing module is enclosed by a cooling body. The coolant or the reducing agent circulates in the cooling body of the internal combustion engine. A cooling spiral is provided, which is embedded with heat transition casting material, such as tin solder, additives of silicon oil, zinc oxide, aluminum, copper, silver or thermoplastic plastic.
