It is the circular arc type groove of circular arc type that said groove adopts a vertical section.The arc radius of said circular arc type groove is 0.1～0.6mm, preferred 0.2～0.4mm.Adopt the circular arc type groove, so that with the heat sink strip roll extrusion on heater tube the time, roll extrusion tightr.
Said heater tube is provided with a cavity, is provided with the PTC heating element that is used to heat in the said cavity.So that air is heated.
Distance between the lower surface of the upper surface of said strip metal body and said strip metal body is 10.0mm～20.0mm, preferred 12.0mm～20.0mm; Distance between the vertical face of the said strip metal body left and right sides is 8.0mm～15.0mm, preferred 8.0mm～12.0mm.
The pipe thickness of said strip metal body is 0.5mm～1.5mm, preferred 0.6mm～1.2mm.
Said insulating barrier, the insulating barrier that adopts insulating paper to constitute.To realize the insulation of PTC heating element and strip metal body.
Said PTC heating element adopts ceramic PTC heating element.Pottery PTC heating element has characteristics such as Fast Heating, the heat efficiency is high, cost is low.
Said PTC heating element adopts the metal PTC heating element.The metal PTC heating element has characteristics such as Fast Heating, heat efficiency height, good stability, inactivity decay, overload capacity are strong.
Owing to adopted technique scheme, the present invention is simple in structure, production cost is low.The present invention is fixed on heat sink strip on the heater tube with the mode of roll extrusion, and fixing is more firm, increases useful life of the present invention, has eliminated the problem that is easy to generate the glue flavor in the heating process.
