摘要： A vehicle auxiliary heating device of the type which has a burner aggregate, a burner pipe forming a combustion chamber and a heat transfer arrangement that contains an inner jacket with ribs and an outer jacket is improved by having the outer jacket and the inner jacket provided with ribs formed of a one-piece extruded profile part. On the ends of the inner and outer jackets facing away from the burner aggregate, lid parts are attached which, preferably, are welded on and effectively are formed by aluminum sheet parts and/or cast parts. Furthermore, the end of the extruded profile part facing the burner aggregate may be shaped to directly provide a receiving flange for the burner aggregate or a closure ring part may be fastened, preferably by welding, at this end of the extruded profile part, for the attachment of the burner aggregate.
