Air heating device for integration into an air-conducting housing arrangement

摘要

An air heating device for integration into an air-conducting housing arrangement, particularly a housing arrangement of a vehicle air conditioner, includes a burner region, a heat exchanger region with a heat exchanger body, wherein in the heat exchanger body a combustion exhaust gas conducting space is constituted in which flow the hot combustion exhaust gases produced in the combustion in the burner region. At an outer side of the heat exchanger body a heat transfer rib arrangement with numerous heat exchange ribs for the air conducted in the housing arrangement to flow around; wherein at least a portion of the heat transfer ribs are constituted separately from the heat exchanger body and are kept in heat transfer contact with this.
