Abstract
An evaporator assembly unit, especially for a vehicle heater or a reformer arrangement of a fuel cell system, includes a wall arrangement (12) enclosing an evaporation chamber (20) with a circumferential wall (14) and with a bottom wall (16). An air introduction shoulder (18) extending in the direction of a wall longitudinal axis (L) is provided with a plurality of first air introduction openings (22). Evaporator medium (26), that is porous at least in some areas, is provided on the side of the wall arrangement (12) facing the evaporation chamber (20). An auxiliary air opening arrangement (34) with at least one second air introduction opening (36) is provided in the wall arrangement (12).
Claims16
An evaporator assembly unit for a vehicle heater or a reformer arrangement of a fuel cell system, the evaporator assembly unit comprising:
- a wall arrangement enclosing an evaporation chamber with a circumferential wall with a wall longitudinal axis and with a bottom wall;
- an air introduction shoulder provided at said bottom wall and extending in the direction of said wall longitudinal axis and with a plurality of air introduction openings;
- a porous evaporator medium provided on a side of said wall arrangement facing said evaporation chamber at least in some sections;
- and
- an auxiliary air opening arrangement having at least one auxiliary air introduction opening in said wall arrangement, at least one auxiliary air introduction opening being provided in said circumferential wall, said circumferential wall comprising two wall components which follow each other in the direction of said wall longitudinal axis, said two wall components being rigidly connected to one another, said auxiliary air introduction opening being formed by an intermediate space between said two wall components.
An evaporator assembly unit comprising:
- a wall arrangement including a circumferential wall extending in an axial direction and with a bottom wall, said wall arrangement defining an evaporation chamber;
- an air introduction shoulder extending interiorly of said circumferential wall and in the axial direction from said bottom wall, said air introduction shoulder having a plurality of air introduction openings;
- an at least partially porous evaporator medium provided on a side of said wall arrangement facing said air introduction shoulder;
- and
- an auxiliary air opening arrangement with an auxiliary air introduction opening in said wall arrangement, said circumferential wall comprising two wall components which follow each other in the axial direction, said two wall components being rigidly connected to one another, said auxiliary air introduction opening being formed by an intermediate space between said two wall components.
