Further, heat-generating pipe is provided with cooling mechanism, cooling mechanism comprises radiating fin, and radiating fin has multiple bending part, and multiple bending part interval on the bearing of trend of heat-generating pipe is arranged.
Further, cooling mechanism also comprises fixed strip, and radiating fin is between fixed strip and heat-generating pipe, and the bearing of trend of fixed strip is identical with heat-generating pipe bearing of trend.
Further, cooling mechanism is two, and heat-generating pipe is between two cooling mechanisms.
Further, electric heater of the present utility model also comprises: electrode terminal, and portion is electrically connected with electric heating.
According to another aspect of the present utility model, provide a kind of courtyard machine, comprising: above-mentioned electric heater.
Application the technical solution of the utility model, because heat-generating pipe is convexly curved, more can adapt to courtyard machine inner for installing the arc space of electric heater, what can contact with air is more abundant, that is, the air flowing through courtyard machine all can contact with heat-generating pipe substantially, and is given heating by heat-generating pipe.As the above analysis, electric heater of the present utility model has better heating effect.
Accompanying drawing explanation
The Figure of description forming a application's part is used to provide further understanding of the present utility model, and schematic description and description of the present utility model, for explaining the utility model, is not formed improper restriction of the present utility model.In the accompanying drawings:
Fig. 1 shows the structural representation of the embodiment according to electric heater of the present utility model.
Wherein, the Reference numeral in above-mentioned figure is as follows:
10, heat-generating pipe; 11, electrode terminal; 20, cooling mechanism; 21, radiating fin; 22, fixed strip.
Embodiment
It should be noted that, when not conflicting, the embodiment in the application and the feature in embodiment can combine mutually.Below with reference to the accompanying drawings and describe the utility model in detail in conjunction with the embodiments.
As shown in Figure 1, the electric heater of the present embodiment comprises heat-generating pipe 10 and electric heating portion.Electric heating portion is positioned at the inside of heat-generating pipe 10, and heat-generating pipe 10 is convexly curved, and that is, heat-generating pipe 10 is curve bend, and its bearing of trend is camber line.Heat-generating pipe 10 is in circular arc.
The electric heater of application the present embodiment, because heat-generating pipe 10 is convexly curved, more can adapt to courtyard machine inner for installing the arc space of electric heater, what can contact with air is more abundant, that is, the air flowing through courtyard machine all can contact with heat-generating pipe 10 substantially, and is given heating by heat-generating pipe 10.As the above analysis, the electric heater of the present embodiment has better heating effect.
In the present embodiment, electric heating portion and heat-generating pipe 10 insulate and arrange, and that is, electric heating portion and heat-generating pipe 10 have clearance for insulation, heat-generating pipe 10 can be prevented charged and cause accident, improve the fail safe of the electric heater of the present embodiment.In addition, be convenient to take out and place electric heating portion.
In the present embodiment, electric heating portion is the electric heating sheets of ceramic PTC.The heating-up temperature of the electric heating sheets of ceramic PTC only has 100 degree, that is, the temperature of heat-generating pipe 10 only has 100 degree, the heat-generating pipe 10 with lower temperature will cause temperature to be elevated to the degree of burn combustible thing because the electric current in electric heating portion is excessive, improves the fail safe of the electric heater of the present embodiment.
In the present embodiment, insulant is provided with between electric heating portion and heat-generating pipe 10.Insulant can play and support the effect in electric heating portion, thus realizes electric heating portion and heat-generating pipe 10 interval and arrange, and is convenient to the transmission of heat, further increases the heating effect of the electric heater of the present embodiment.
In the present embodiment, insulant is be wrapped in the insulating paper in electric heating portion.Adopt said structure, be convenient to take out and place electric heating portion.
As shown in Figure 1, in the present embodiment, heat-generating pipe 10 is provided with cooling mechanism 20, cooling mechanism 20 comprises radiating fin 21, and radiating fin 21 has multiple bending part, and multiple bending part interval on the bearing of trend of heat-generating pipe 10 is arranged.Fig. 1 only illustrates a part for radiating fin 21, and not all.Radiating fin 21 absorbs the heat of heat-generating pipe 10 and distributes, and increases the contact area that contacts with air and be convenient to air to pass, and further increases the heating effect of the electric heater of the present embodiment.Each bending part forms gas flow, and the through direction of gas flow is identical with the wrap direction (in Fig. 1, heat-generating pipe 10 is bendings obliquely upward) of heat-generating pipe 10.
As shown in Figure 1, in the present embodiment, cooling mechanism 20 also comprises fixed strip 22, and radiating fin 21 is between fixed strip 22 and heat-generating pipe 10, and the bearing of trend of fixed strip 22 is identical with heat-generating pipe 10 bearing of trend, and that is, fixed strip 22 is convexly curved.Fixed strip 22 plays the effect of stable radiating fin 21 structure, avoids radiating fin 21 to be out of shape.
As shown in Figure 1, in the present embodiment, cooling mechanism 20 is two, and heat-generating pipe 10 is between two cooling mechanisms 20.Adopt said structure, further increase the heating effect of the electric heater of the present embodiment.
As shown in Figure 1, the electric heater of the present embodiment also comprises electrode terminal 11, and electrode terminal 11 is electrically connected with electric heating portion.Electrode terminal 11 is convenient to be connected with terminals or distribution.Electrode terminal 11 is multiple, for connecting obstructed electrode.
Present invention also provides a kind of courtyard machine, the courtyard machine (not shown) of the present embodiment comprises the electric heater of above-described embodiment.The courtyard facility of the present embodiment have better heating effect.
The foregoing is only preferred embodiment of the present utility model, be not limited to the utility model, for a person skilled in the art, the utility model can have various modifications and variations.All within spirit of the present utility model and principle, any amendment done, equivalent replacement, improvement etc., all should be included within protection range of the present utility model.
