Abstract

The utility model relates to a single-side heating body. The single-side heating body comprises heating wires and a flaky substrate attached with the heating wires, wherein tooth-shaped concave-convex portions are formed on two sides of the flaky substrate, the heating wire is wound on the flaky substrate; on the front surface of the flaky substrate, the heating wires span between the tooth-shaped concave-convex portions on the two sides; and on the back surface of the flaky substrate, the heating wires are alternatively distributed along the tooth-shaped concave-convex portion on the same side; and two ends of the heating wires are welded on the surface of the flaky substrate. By adopting the above structure, most of the heating wires are arranged on the front surface of the flaky substrate, and the heating wires are distributed on the back surface of the flaky substrate along the width direction of only half of the tooth-shaped concave-convex portions, the length of the heating wire on the back surface accounts for a small percentage of the total length of the heating wires, thus the heating amount of the heating wires mainly concentrates on the front surface of the flaky substrate, and the heating amount on the back surface is very small, therefore the single-side heating body is formed. The heating amount of the single-side heating body is more concentrated, the heat loss is smaller, larger space of the product is saved, the production cost is saved, and the heating effect is stable.

Description

A kind of single-side heating body

Technical field:

The utility model belongs to technical field of electronic products, relates to electric heating products, refers in particular to the single-side heating body.

Background technology:

What electric heating products commonly used mainly adopted at present is the resistance-type heating, the PTC heater, Electric radiant Heating Film, with exothermic materials such as common heating wires, wherein, when adopting the heating wire material to make heater, normally heating wire is wrapped on the matrix so that the heating wire typing, namely heatable after the energising, but, this class heater adstante febre is because heating wire centers on the matrix design, therefore the adstante febre all directions all can produce heat, so just cause the heat utilization rate of heater not high, produce larger heat waste, and, this class heater must arrange heat-barrier material at corresponding position when installing and using, otherwise its heating can make the parts of electric equipment products impaired or reductions of service life own.

The utility model content:

The purpose of this utility model is to overcome the above-mentioned weak point of existing heater, provides that a kind of concentrated, hot utilization rate of generating heat is high, the single-side heating body of conserve space and cost more.

The utility model realizes that the technical scheme that its purpose adopts is: a kind of single-side heating body, comprise heating wire and be used for adhering to the plate shape substrates of heating wire, the both sides of this plate shape substrates form the dentation jog, described heating wire is wound on the plate shape substrates, and the front at plate shape substrates, heating wire is across between the dentation jog of both sides, and at the back side of plate shape substrates, heating wire compartment ground distributes along the dentation jog of homonymy; The both ends of heating wire are welded in the surface of plate shape substrates.

The both ends of described heating wire are welded on the back side of plate shape substrates.

The solder joint place at described heating wire both ends also is connected with respectively lead-in wire.

After the utility model adopts said structure, the major part of heating wire all is positioned at the front of plate shape substrates, and the back side only is distributed with heating wire on the Width of half dentation jog, the ratio that its length accounts for the heating wire total length is very little, therefore, the main heating of heating wire all concentrates on the front of plate shape substrates, and the heating at the back side is very little, thereby forms the single-side heating body; The utility model single-side heating body is not only simple in structure, manufacture craft is easy, compare with the multiaspect heater of traditional whole wound form, generate heat more concentrated, thermal loss is less, more saves product space and cost of manufacture, with respect to prior art, in the situation of the heating wire that adopts equal length, the efficient of the utility model single-side heating body is higher, and heating is stable.

Description of drawings:

Fig. 1 is the structural representation of a kind of embodiment of the utility model;

Fig. 2 is the schematic diagram at the utility model embodiment single-side heating body back side.

Embodiment:

Below in conjunction with specific embodiments and the drawings the utility model is further specified.

As shown in Figure 1, 2, single-side heating body described in the utility model, comprise heating wire 1 and be used for adhering to the plate shape substrates 2 of heating wire 1, the both sides of this plate shape substrates 2 form dentation jog 21, the number of the dentation jog 21 of both sides can be the same or different, and can symmetrically also can be dislocatedly distributed; For example, the number of the dentation jog 21 of upside is 6 among the present embodiment figure, and downside is 7, and both sides are the mutual dislocation distribution.Described heating wire 1 is wound on the plate shape substrates 2, and in the front of plate shape substrates 2, heating wire 1 is across between the dentation jog 21 of both sides, and at the back side of plate shape substrates 2, heating wire 1 compartment ground distributes along the dentation jog 21 of homonymy; When namely twining heating wire 1, twine along the Width of plate shape substrates 1 in the front, in the time of overleaf, walk around dentation jog 21 along the length direction of substrate, the front of wraparound plate shape substrates 1 again, so uniform winding gets final product.Like this, the major part of heating wire 1 all is positioned at the front of plate shape substrates 2, and the back side only is distributed with heating wire on the Width of half dentation jog 21, the ratio that its length accounts for the heating wire total length is very little, therefore, the main heating of heating wire all concentrates on the front of plate shape substrates 2, and the heating at the back side is very little, thereby forms the single-side heating body.The both ends of heating wire 1 are welded in the surface of plate shape substrates 2.

In the present embodiment, the both ends of heating wire 1 are welded on the back side of plate shape substrates 2, and the solder joint place at both ends also is connected with respectively lead-in wire 3.The both ends of heating wire 1 be welded on plate shape substrates 2 back sides be for the front that keeps plate shape substrates 2 more smooth, thereby be conducive to contacting between plate shape substrates 2 and heating object such as heat-conducting plate etc., be more conducive to the heat transmission.

The heating wire that uses in the present embodiment is variable heating wire, under heating wire total length 30cm, string diameter 0.14mm specification, its resistance is about 5.8 Ω, rated power is 3W, heating wire 1 is fastened on the plate shape substrates 2 of dimension by diagramatic way, when passing to the 5V direct voltage, the heating temp in single-side heating body front can reach 80 ℃ ~ 90 ℃, go for the small-sized heaters such as USB heating cup pad, USB essence device, USB humidifier, be particularly useful for the dewaxing essence box take solid wax as consumptive material.

To sum up, the utility model single-side heating body is not only simple in structure, manufacture craft is easy, compares with the multiaspect heater of traditional whole wound form, generates heat more concentrated, thermal loss is less, more save product space and cost of manufacture, with respect to prior art, in the situation of the heating wire that adopts equal length, the efficient of the utility model single-side heating body is higher, and heating is stable.
