A combustion chamber assembly unit for a fuel-operated vehicle heater includes a mixing chamber () extending in a direction of a combustion chamber assembly unit longitudinal axis (L) for generating an air/fuel mixture. A fuel feed device () feeds fuel to the mixing chamber () and a combustion air feed device feeds combustion air to the mixing chamber (). A diffuser device () is arranged downstream in relation to the mixing chamber () in the direction of the combustion chamber assembly unit longitudinal axis (L). The fuel feed device () includes an evaporator device (). The combustion air feed device () includes a swirling flow generation device (). The swirling flow generation device () is arranged with the evaporator device () upstream in relation to the mixing chamber () in the direction of the combustion chamber assembly unit longitudinal axis (L).

Combustion chamber assembly unit for a fuel-operated vehicle heater

A vehicle heater housing () has an inlet area (), an outlet area () and an air flow space () for air to be heated with a burner chamber assembly unit (), to be fed with combustion air and fuel. A heat exchanger area (), including a heat exchanger housing (), is elongated in the direction of a housing longitudinal axis (L) with an outer side () around which air flowing in the air flow space flows. Heat transfer ribs are on a side of the heat exchanger housing. The heater housing has a housing circumferential wall () and an outlet front wall area (). The heat transfer ribs have a longitudinal edge () extending along the housing circumferential wall and a radial edge extending along the outlet front wall area. A distance of the radial edge from the outlet front wall area changes from radially outwards to radially inwards.
