    • The invention relates to an electrical vehicle heating device (1) comprising: at least one substantially plate-shaped ceramic PTC heating element (2), which has a first main surface (2a) and a second main surface (2b) opposite the first main surface; a metal first contacting layer (4), which electrically contacts the first main surface (2a) substantially over the full area; a metal second contacting layer (3), which electrically contacts the second main surface (2b) substantially over the full area; an electrically insulating, ceramic first insulating structure (5), which covers a side of the first contacting layer (4) facing away from the first main surface (2a); and an electrically insulating, ceramic second insulating structure (6), which covers a side of the second contacting layer (3) facing away from the second main surface (2b). The PTC heating element (2), the first contacting layer (4), the second contacting layer (3), the first insulating structure (5), and the second insulating structure (6) are connected to each other in a bonded manner.
    • 提供了一种电动车辆加热设备(1),包括:至少一个具有第一主表面(2a)和与其相对的第二主表面(2b)的基本上板形的陶瓷PTC加热元件(2) 基本上在整个区域上与第一主表面(2a)电接触的金属第一接触层(4) 基本在整个区域上电接触第二主表面(2b)的金属第二接触层(3) 覆盖第一接触层(4)远离第一主表面(2a)的一侧的电绝缘陶瓷第一绝缘结构(5); 以及覆盖第二接触层(3)的远离第二主表面(2b)的一侧的电绝缘陶瓷第二绝缘结构(6)。 PTC加热元件(2),所述第一接合层(4),所述第二粘接层(3),第一绝缘结构(5)和第二绝缘结构(6)相互接合。
