The metal tube body 110 has opposite inner and outer surfaces, and the inner surface of the metal tube body 110 forms an inner space for accommodating a body to be heated (not shown). The semiconductor insulating layer 120 is disposed on one side of the outer surface of the metal body 110, and the metal body 110 is isolated from the outside of the metal body 110 by the semiconductor insulating layer 120.
As shown in fig. 1, in an embodiment, the semiconductor insulating layer 120 may have a single-layer structure, and the semiconductor insulating layer 120 includes a semiconductor material and a thermal conductive adhesive. And the semiconductor material is doped in the heat-conducting glue to form mixed semiconductor glue. The semiconductor paste may be applied to the outer surface of the metal pipe body 110, thereby forming the semiconductor insulating layer 120.

The semiconductor material layer 122 is adhered to the outer surface of the metal tube 110 by the heat conducting glue or the heat conducting sheet, so that the formed heating tube 11 has a good heat conducting effect.

Specifically, the semiconductor insulating layer 120 may cover only a portion of the metal body 110 and expose another portion of the metal body 110.
