The angle of the vertical face of each the said flange and the said strip metal body left and right sides is provided with groove.
The upper surface and the lower surface both sides of said strip metal body are respectively equipped with flange, and therefore the shape of said strip metal body is just like same " II " word.In the use, heat sink strip is placed on the left and right sides of said heater tube, with each said flange bending, said heat sink strip is stuck on the heater tube then through flange.With respect to gluing mode, avoided producing the problem of glue flavor, reduced chemical contamination, environmental protection has more been avoided because the aging back of glue produces loosening problem simultaneously, and service time is longer.With respect to the traditional heating organ pipe, be applicable to fields such as small-sized electric heater, air-conditioning, auto heater, aircraft heater, train heater, heater peculiar to vessel more.When being applied to room conditioning, advantage is more outstanding.
Angle at the vertical face of said flange and strip metal body is provided with groove, can be so that adopt each flange of roll extrusion technology turnover.When adopting each flange of roll extrusion technology turnover, because the groove material is thinner, folding is moving easily, so the folding line rule, and makes combination more firm.
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～16.0mm; 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 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 utility model is simple in structure, production cost is low.The utility model is fixed on heat sink strip on the heater tube with the mode of roll extrusion, and fixing is more firm, increases the useful life of the utility model, has eliminated the problem that is easy to generate the glue flavor in the heating process.
Description of drawings
Fig. 1 is the structural representation of a kind of electric heater with II type pipe;
Fig. 2 is the side structure sketch map that heat sink strip is housed.
Embodiment
For technological means, creation characteristic that the utility model is realized, reach purpose and be easy to understand with effect and understand, below in conjunction with the further elaboration the utility model of concrete diagram.
With reference to Fig. 1, a kind of electric heater comprises that with II type pipe one is used to place the heater tube of heating element.Heater tube adopts a strip metal body 1.Upper surface 2 both sides of strip metal body 1 are respectively equipped with flange.Lower surface 3 both sides of strip metal body 1 are respectively equipped with flange 13.The angle of the vertical face of each flange and strip metal body 1 left and right sides is provided with groove 14.The upper surface 2 and lower surface 3 both sides of strip metal body 1 are respectively equipped with flange 12,13, so the shape of strip metal body 1 is just like same " II " word.
