The invention describes an electric heating unit for preventing and removing ice. The electric heating unit comprises: a base body made of an insulating material; an electric heating film located on one surface of the base body, wherein the electric heating film is made of an alloy material and comprises at least two heating strips, and corner transition areas are arranged at the adjacent ends ofthe heating strips; and a transition film made of the metal material, wherein the shape of the transition film is consistent with the shape of the corner transition areas of the heating strips, and the transition film is overlapped on the corner transition areas of the electric heating film. Due to the structural design that the good conductor is adopted at the corners of the electric heating filmfor transition, the problem that local heating is uneven, especially overheating is caused due to the fact that currents flow through the corners of the electric heating film in a near-line mode is effectively solved while the preset current transmission function is achieved.

    本发明描述了一种用于防冰除冰的电加热单元,其包括:基体,所述基体由绝缘材料构成;电加热膜,所述电加热膜位于所述基体的一表面上,所述电加热膜由合金材料构成并且包括至少两个加热条,在所述加热条的相邻端处具有拐角过渡区域;过渡膜,所述过渡膜由所述金属材料构成,所述过渡膜的形状与所述加热条的所述拐角过渡区域的形状相一致,并且所述过渡膜叠置在所述电加热膜的所述拐角过渡区域上。根据本发明,由于在电加热膜拐角位置处采用良好导体进行过渡的结构设计,由此在完成预定电流传输功能的同时,还有效地解决了电加热膜拐角位置因电流在电加热膜内部“抄近道”而导致局部加热不均、尤其是过热的问题。
