ABSTRACT:
In a heating device, particularly one intended for use as a vehicle auxiliary heating device, a heat exchanger is provided for a liquid heat exchange medium, which is of a quadrangular, preferably cuboid design, having a planar closed end. Inside the heat exchanger, inner fins are provided defining exhaust gas channels, whose free ends are approximately on a circle whose center is the center axis of the heat exchanger or that of the cylindrical combustion chamber as a transition between the cylindrical combustion chamber and a rectanguloid outer housing which surrounds the heat exchanger. An outer, flat surface of the housing may be formed with a receiver for a control or similar device. For optimizing the transfer of heat from the hot combustion gases at the inner side of the heat exchanger to the liquid heat exchange medium at the exterior of the heat exchanger, baffles are provided on the outer surface of the heat exchanger for guiding the liquid heat exchange medium in a manner which facilitates removal of steam or air bubbles therefrom and which adapts the flow of the liquid heat exchange medium to the heat flow at the respective surface of the heat exchanger.
