Heating flange () for heating a flow of gas as it flows though a cross-section of flow (S), wherein the heating flange () is designed such that it can be inserted or interposed in an intake line (A) of an internal combustion engine and has at least one heat conductor () that extends through the cross-section of flow (S) from a mounting point () to an immediately following further mounting point () on the heating flange (), as well as a retaining leg piece (), which is provided with at least one of the mounting points (). In order to create an improved heating flange of a simple and robust construction that is easier to manufacture, mount and maintain, according to the invention, it is provided for the longitudinal axis of the one retaining leg piece () to form a triangle, on the one hand, with two heating leg pieces () of the heat conductor () between the one mounting point () and the other mounting point (), which is likewise arranged on the one retaining leg piece (), or, on the other hand, with the longitudinal axis of a further retaining leg piece (), on which the further mounting point () is provided, as well as with the straight line through the one () and the other mounting point ().

Heating flange with geometrically stable structure

The present invention relates to a heating flange, in particular for preheating air in an intake line leading to an internal combustion engine. The heating flange comprises at least one heating element for heating the air flowing past said heating element, and a body for mechanically holding and electrically contacting said heating element. For providing an improved heating flange, which is used in particular for preheating air in an intake line leading to an internal combustion engine and which guarantees fast heating of the intake air as well as increased robustness and simplified mounting, said body comprises a fastening bow having a substantially U-shaped cross-section, and said heating element comprises at least one substantially U-shaped meander loop which is fixedly connected to the base of said fastening bow.
