Abstract
An evaporation unit for producing a gas flow including ammonia, in particular in connection with an SCR system in motor vehicles, includes at least a housing, at least one meandering flow channel delimited by a closed wall and having an inlet and an outlet and at least one heat conductor disposed in a first evaporation section of the at least one flow channel coaxially between the housing and the wall. A device and a motor vehicle having the evaporation unit are also provided.
Claims18
An evaporation unit for producing a gas flow including ammonia, the evaporation unit comprising:
- a central axis;
- a housing formed by steel material;
- at least one meandering flow channel having an inlet, an outlet, a first evaporation section and a closed wall delimiting and forming said at least one flow channel;
- said closed wall being formed by a tube including titanium;
- said at least one meandering flow channel having a periodic change in profile about said central axis;
- at least one heat conductor disposed at least in said first evaporation section of said at least one flow channel coaxially between said housing and said wall;
- and
- a basic body including at least aluminum or copper;
- at least said at least one flow channel or said at least one heat conductor being cast into said basic body causing said at least one heat conductor to be spaced apart from said housing and said at least one flow channel at least in said first evaporation section.
