Abstract
The invention discloses a flat heating wire comprising a heating wire. The heating wire is a flat resistance heating wire. The surface of the heating wire is covered with an insulated layer which is a polychlorotrifluoroethylene layer. Compared with the previous cylindrical heating wire, in the condition of the same volume and length, the flat heating wire has the advantages of smaller cross-sectional area, larger resistance, higher heating amount, larger surface area, faster heat radiation, and great improvement of heating efficiency.
Description
Technical field
The present invention relates to a kind of Electrothermic wire, especially a kind of heating wire of flat structure.
Background technology
Existing resistive heater normally cross section is circular heating wire, the resistance wire of equal length, its area of section is less, and resistance is larger, and is also larger by its caloric value of same current, but when reducing circular cross-sectional area, the surface area of heating wire also can correspondingly reduce, so that its heating area reduces greatly, affects its efficiency of heating surface, and circular cross-section is less, and resistance wire more easily blows or fractures.
Summary of the invention
In order to solve the problems of the technologies described above, a kind of flat heating wire provided by the invention, the cross section is the flat structure, and heating area is larger during energising, and the efficiency of heating surface is higher.
To achieve these goals, the technical solution adopted in the present invention is:
A kind of flat heating wire comprises heating wire, and described heating wire is the resistive heater of flat, heating wire surface coverage one layer insulating.
As further improvement in the technical proposal, described insulating barrier is the polytrifluorochloroethylene layer.
The further improvement of technique scheme, described heating wire is winding structure in the shape of a spiral.
The further improvement of technique scheme, described heating wire undulate structure.
Beneficial effect of the present invention: flat heating wire of the present invention, compare cylindrical heating wire in the past, in the situation that equal volume and length, the area of section of flat heating wire is less, and resistance is larger, caloric value is higher, and its heating area is also larger, dispels the heat faster, and the efficiency of heating surface improves greatly, be not easy to blow or fracture, also further improve useful life.
Description of drawings
Below in conjunction with accompanying drawing the specific embodiment of the present invention is described further.
Fig. 1 is schematic diagram of the present invention.
Fig. 2 is helicoidal structure schematic diagram of the present invention.
Fig. 3 is wavy shaped configuration schematic diagram of the present invention.
Embodiment
With reference to Fig. 1; a kind of flat heating wire provided by the invention; comprise heating wire 1; described heating wire 1 is the resistive heater of flat; heating wire 1 surface coverage one layer insulating; described insulating barrier is the polytrifluorochloroethylene layer, has good chemical stability, insulating properties and heat-resisting quantity, effectively protects heating wire 1.
The heating wire 1 of said structure, section thickness is less, its cross-sectional width is larger, be the heating wire 1 more flat sheet that levels off to, coiling is convenient, is not easy to fracture, make in the shape of a spiral winding structure of coiling heating wire 1 by equipment, or the undulate structure, referring to Fig. 2 and shown in Figure 3, the present invention is not limited to above-mentioned two kinds of embodiment.
Flat heating wire 1 of the present invention is compared cylindrical heating wire in the past, in the situation that equal volume and length, the area of section of flat heating wire 1 is less, and resistance is larger, and caloric value is higher, and heating surface is long-pending large, and heating rapidly.
The above is preferred embodiment of the present invention, and the present invention is not limited to above-mentioned execution mode, as long as it reaches technique effect of the present invention with identical means, all should belong to protection scope of the present invention.
