A flow-directing insert for a heating device having an evaporator burner, wherein: the evaporator burner has a fan chamber or combustion air pre-chamber, an evaporator holder and a combustion chamber, the evaporator holder has a base wall and a circumferential wall with at least two combustion air passage openings to direct combustion air from the fan chamber or combustion air pre-chamber initially along an exterior of the evaporator holder through the combustion air passage openings into the combustion chamber, the flow-directing insert comprises at least a first region for positioning over at least one of the combustion air passage openings and a second region for fixing in the fan chamber or combustion air pre-chamber of the evaporator burner, the first region being in the shape of a tongue.

A hot air feed wheel, for a vehicle heater, includes a hub (44) to fix the hot air feed wheel (22) to a drive shaft and a feed area (50), adjacent to the hub (44), in a transition area (48). A plurality of feed blades (36) are arranged following one another about a feed wheel longitudinal axis (L) in the circumferential direction. The transition area (48) includes a plurality of connection webs (66) following one another about the feed wheel longitudinal axis (L) in the circumferential direction.

A heating apparatus for a vehicle includes: a heat-generating apparatus including a heat-generating portion generating heat and a heat-insulating portion positioned above the heat-generating portion and insulating the heat generated from the heat-generating portion; and a storage apparatus storing the heat-generating apparatus.

The present invention relates to a vehicle air conditioning device capable of improving sealing ability by doubly sealing a defrost vent of an air conditioning case, and increasing the amount of airflow discharged inside a vehicle while simultaneously preventing an increase in the amount of force needed to actuate a face door and, more particularly, to a vehicle air conditioning device comprising: a ball; the air conditioning case in which a floor vent is formed; a defrost door installed to be rotatable via rotation shafts respectively inside the air conditioning case, and opening and closing each of the vents; the face door; the defrost vent for discharging air entering through the floor door and an air inlet inside the air conditioning case; and a face vent (in the passage of which an evaporator and a heater core are installed in that order), wherein the vehicle air conditioning device is characterized in that the face door is configured to doubly seal the defrost vent.

A combustion chamber assembly unit, for a fuel-operated vehicle heater, includes a combustion chamber housing (12) with a combustion chamber (18) defined by a circumferential wall (14) and by a bottom area (16). A flame tube (30) follows the circumferential wall (14) in the direction of a housing longitudinal axis (L) and encloses a waste gas flow space (32) that is open in the direction of the housing longitudinal axis (L). A flame diaphragm (34) has a flow-through opening (60). A waste gas backflow space (46) is formed between the flame tube (30) and a housing (38) enclosing same. The waste gas flow space (32) is open towards the waste gas backflow space (46) in a first axial end area (48) of the waste gas backflow space (46). A catalytic converter device (54), through which combustion waste gases can flow, is provided in the waste gas backflow space (46).

A delivery device provides two medium flows guided separately from one another in a fuel-operated vehicle heater. The delivery device includes a first delivery wheel (14) rotatable about a first rotation axis (A) for delivering a first medium, a second delivery wheel (16) rotatable about a second rotation axis (A) for delivering a second medium, as well as a drive motor (12) for driving the first delivery wheel (14) and the second delivery wheel (16). At least one delivery wheel (16) is coupled with the drive motor (12) via a magnetic coupling device (60).

A heating apparatus for generating a hot air flow comprises a single fan, a burner heating element and a resistance heating element. In this respect, an air passage that conducts air to be heated and a combustion air passage that leads to a burner adjoin the fan downstream, wherein a combustion air flow in the combustion air passage can be controlled by a control element associated with the combustion air passage.
