| 摘要 |
The invention relates to an electrical heating module for airflow heating. Said electrical heating module comprises at least one planar PTC element having a first contact surface and a second contact surface, a heat output region, through which air can flow and in which thermally conductive fins are arranged, which fins are connected to the PTC element in a thermally conductive manner, and a thermally and electrically conductive core, which bears the fins and which can be divided into a first core part and a second core part, wherein the PTC element is arranged between the first core part and the second core part and lies against the first core part at the first contact surface of the PTC element and against the second core part at the second contact surface of the PTC element. Furthermore, a fastening element is provided, which passes through the first core part, the PTC element, and the second core part and fastens the first core part, the PTC element, and the second core part to one another. |
