Description
The utility model relates to a kind of constant temperature far-infrared electric body.
At normal temperatures, when electric current passes through conductor, owing to the resistance reason all will produce heat.So people according to this characteristic, develop various electric heating appliances, to satisfy people's needs.But along with the variation of ambient temperature and voltage, and problem such as product quality occurs, and makes electric heating appliance often break down, and gently then damages, heavy then fire hazardous.
The purpose of this utility model provides a kind of constant temperature far-infrared electric body, this electric heating element safety, reliable, volume is little, it is simple not take up space, make.This electric heating element has thermostatic characteristics.
For achieving the above object, the utility model is taked following design: this constant temperature far-infrared electric body is three layers; Bottom is an insulation board, and the middle level is a conductive layer, and the upper strata is an insulating protective layer, and wherein, conductive layer is made up of with the conductive electrode that its two opposite sides end is connected the firming body of far infrared conductive liquid.
In the utility model, far infrared conductive liquid firming body can be different shape: plane, and linearity, curve-like.
In the utility model, the firming body of described far infrared conductive liquid is plane.
In the utility model, some the isometric linearities of the firming body of described far infrared conductive liquid for equidistantly being arranged in parallel, described conductive electrode is positioned at the place, two ends of some linearities.
In the utility model, some the same curve shapes of the firming body of described far infrared conductive liquid for equidistantly being arranged in parallel, described conductive electrode is positioned at place, some curvilinear two ends.
The utility model is described in further detail below in conjunction with accompanying drawing.

1, i.e. the purpose of constant temperature.
With conductive liquid by air brushing, wire mark, brushing flexo technology on insulation board 1, make (as Fig. 2) plane 2; Or isometric, equally spaced (as shown in Figure 3) linearity 12; or equally spaced identical curve-like 22 (as shown in Figure 4); two ends also are provided with the conductive coating of conductive electrode 3; topped more above one deck insulation insulating protective layer; dried 20 to 40 minutes down at 100 ℃ the encapsulation back, makes the utility model far-infrared electric body.This product can be widely used in each motor vehicle cold start-up, the defrosting of various apparatus, house heating residential, agricultural greenhouse heat and water in heating every field such as (as fish jars).
Conductive liquid compound method of the present utility model is as follows:
One, the conductive liquid proportioning (by weight percentage) of 40 ℃ of design temperatures
1, by liquid rubber, the macromolecule carrier 45% that synthetic cement or latex are formed;
2, the conductive filler of forming by carbon black, graphite powder, metal powder or conductive fiber 10%;
3, the far-infrared composite material 35% of carborundum, quartz, diatomite, bentonite composition;
4,10% of the oxide of forming by zinc oxide, aluminium oxide, manganese oxide;
5, above-mentioned raw materials fully mixed.
When two, design temperature was 70 ℃, the said sequence proportioning was high score carrier 30 as one kind %; Conductive filler 40%, far-infrared composite material 25%, oxide 5%.
In sum, electric heating element safety of the present utility model, reliable, volume is little, do not take up space, and makes simply, and has thermostatic characteristics.
