EXHAUST GAS HEATER

To provide an exhaust gas heater in which an assembly that is stable irrespective of the temperature of the exhaust gas heater is ensured.SOLUTION: An exhaust gas heater for an exhaust device of an internal combustion engine includes a carrier assembly 24, and a heating conductor assembly 18 having at least one heating conductor 14, 16. The at least one heating conductor 14, 16 is supported with respect to the carrier assembly 24 by at least one connecting element 32, which is elongate in the direction of a connecting element longitudinal axis V. At least one length compensation assembly 44 is provided in association with at least one connecting element 32, the at least one length compensation assembly having a first length compensation element 46, which has a first supporting surface 54 providing a wedge formation, and a second length compensation element 48, which has a second supporting surface 56 supported on the first supporting surface 54 and providing a counter-wedge formation. The first length compensation element 46 and the second length compensation element 48 have different coefficients of thermal expansion which are different from one another.SELECTED DRAWING: Figure 3 【課題】排ガスヒータの温度に左右されない安定した複合が保証されている排ガスヒータを提供する。【解決手段】内燃機関の排ガス装置用の排ガスヒータは、少なくとも１つの加熱導体１４，１６を備えた加熱導体アセンブリ１８とを備え、少なくとも１つの加熱導体１４，１６は、結合要素長手方向軸線Ｖの方向に長く延在した少なくとも１つの結合要素３２によって支持アセンブリ２４に対して支持されており、少なくとも１つの結合要素３２に割り当てられて、楔構成を提供する第１の支持面５４を備えた第１の長さ補償要素４６と、第１の支持面５４に支持されていて、対応楔構成を提供する第２の支持面５６を備えた第２の長さ補償要素４８とを有する少なくとも１つの長さ補償アセンブリ４４が設けられており、第１の長さ補償要素４６と第２の長さ補償要素４８とは、互いに異なる熱膨張係数を有する。【選択図】図３
