Zusammenfassung:To provide an exhaust heater in which stable coupling between a heating conductor unit and a support unit is guaranteed on high exhaust temperatures in particular in improved heat transfer characteristics.SOLUTION: The exhaust heater for an exhaust device of an internal combustion engine has a support unit 12 and a heating conductor unit 20 including at least one heating conductor 22, 24 supported by the support unit 12. The support unit has an annular first support member 14 surrounding a longitudinal axis L of the exhaust heater and a plurality of second support members 16, 18 formed separately from the first support member 14, coupled with the first support member 14 in first coupling areas 52, 76, and coupled with a link area 44 of the heating conductor unit 20 in a second coupling area 54.SELECTED DRAWING: Figure 1 【課題】改良された熱伝達特性において、特に高い排気温度の場合に加熱導体ユニットと支持体ユニットとの安定的な結合が保証されている排気ヒータを提供する。【解決手段】内燃機関の排気装置用の排気ヒータであって、支持体ユニット12と、支持体ユニット12に支持された、少なくとも1つの加熱導体22,24を備える加熱導体ユニット20とを有しており、支持体ユニットは、排気ヒータ長手方向軸線Lを取り囲む環状の第1の支持体部材14と、第1の支持体部材14とは別個に形成された、第1の結合領域52,76において第1の支持体部材14に結合されかつ第2の結合領域54において加熱導体ユニット20の連結領域44に結合された複数の第2の支持体部材16,18を有している。【選択図】図1
