The invention relates to a heating unit and a PTC heating device. The heating device comprises a framework (2) made of an electrically insulated material, a PTC element accommodated in the framework opening (6) of the framework (2), and insulating layers (16) for accommodating (enclosing) the PTC element therebetween. The insulating layers are connected to the framework (2). Through the insulating layers, the PTC element (14) is exposed to the corresponding main lateral surface of the framework opening (6), and the framework surface (4) defining the framework opening (6) is at least partially covered. The abut protrusions (8) of the insulating layers protrude and exceed the framework surface (4) and completely or locally enclose the peripheries of the insulating layers (16)or surround the edge.

    本发明涉及一种加热单元和一种PCT加热装置,加热单元具有由电绝缘材料制成的框架(2)、容纳在框架(2)的框架开口(6)中的PTC元件(14)和在彼此之间容纳(包围)PTC元件的绝缘层(16),绝缘层连接到框架(2),并且通过绝缘层,PTC元件(14)的暴露在框架开口(6)中的相应主侧表面和限定框架开口(6)的框架表面(4)至少部分地被覆盖,其中,用于绝缘层(16)的抵靠突起(8)突出超过框架表面(4)并完全地或部分地在彼此之间包围绝缘层(16)的周向环绕边缘。
