| 摘要 |
<p>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.</p> |
