摘要 |
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 (10). An outer surface (34) of the metering module (10) is enclosed by a cooling member (18, 20, 22) through which the cooling fluid flows. The multi-part cooling member (18, 20, 22) comprises drainage openings (30) for discharging (78) the cooling fluid/for discharging liquids in order to prevent said fluid/liquids from accumulating on the bottom of the cooling member (18, 20, 22). |
