The invention relates to an electric heating device having at least two hollow contour elements (2), which form a fluid channel (8) for a fluid to be heated, and a heating chamber (24) opposite the fluid channel (8), the heating chamber (24) being delimited by opposite contact surfaces (4) on which at least one PTC element (20) rests in a thermally conductive manner. According to the invention, the hollow profile elements (2) are connected to each other by means of complementary form-fitting sections (10, 12), allowing the electrical heating device to be extendable and more convenient to assemble.
本发明涉及一种电加热装置,该电加热装置具有至少两个中空的轮廓元件(2)以及与流体通道(8)相对的加热室(24),该中空的轮廓元件(2)形成用于待加热流体的流体通道(8),加热室(24)由相对的接触表面(4)限界,至少一个PTC元件(20)以导热方式抵靠在该接触表面(4)上。通过本发明中中空的轮廓元件(2)借助互补的形状配合段(10、12)相互连接,实现了对电加热装置的可扩展和更方便的组装。
