Abstract
The invention relates to a device for cooling a metering module, in particular a module for metering an operating agent/auxiliary agent such as a reducing agent into the exhaust gas system of an internal combustion engine. A cooling device through which a cooling fluid flows is associated with the metering module (). An outer surface () of the metering module () is enclosed by a cooling member () through which the cooling fluid flows. The multi-part cooling member () comprises drainage openings () for discharging () the cooling fluid/for discharging liquids in order to prevent said fluid/liquids from accumulating on the bottom of the cooling member ().
