Description

Surface type heater which emits infrared rays}

The present invention relates to a far-infrared radiant planar heating element using carbon fiber yarns, and in particular, by making grooves having a predetermined interval of lattice shape on the inner surface of the polymer insulating member and arranging carbon fiber heating wires along the grooves, It is possible to manufacture a carbon fiber yarn heating wire of a desired shape, including the shape, to provide a far-infrared radiation planar heating element having excellent far-infrared radiation characteristics and low production cost.

General planar heating element uses radiant heat generated by electric current, so it is easy to control temperature and is not polluted with air, so it is hygienic and no noise, so heating mat, heating pad, bed mattress, insulation blanket or blanket, apartment or general house It is widely used for residential heating equipment.

It also prevents the melting of snow or freezing of roads and parking lots, such as heating devices in commercial buildings such as offices and shops, industrial heating devices in workshops, warehouses, barracks, and other industrial heating devices, agricultural facilities such as vinyl houses and agricultural product drying systems. In addition to various freeze protection devices that can be used, it is also used for leisure, cold protection, home appliances, anti-fog of mirrors and glass, health supplement, livestock.

As a heating source of the planar heating element, metal heating wires such as nichrome and copper nickel alloys are mainly used. However, since the metal heating wires such as nichrome flow through one wire, if any part is broken, electricity does not pass through the entire heating wire. Therefore, there is a problem in losing the function as a heating element.

In addition, since the planar heating element using the metal heating wires listed above is a partial heating method in which only the heating wire portion is heated, there is a problem that the temperature distribution is unevenly formed.

In addition, metals such as nichrome have a low emissivity of far-infrared rays, so that heating of an object is performed by convection, so that energy efficiency is lower than that of radiation, and the effect of far-infrared rays is not available.

In order to solve the problem in the conventional planar heating element using the metal heating wire, instead of using a metal heating wire such as nichrome, a method using a carbon fiber yarn woven fabric woven with carbon fiber yarn has been proposed.

Since carbon fiber yarn has excellent far-infrared emissivity, the planar heating element using carbon fiber yarn heating fabric can be heated by radiation to improve energy efficiency, and additionally, various useful effects of far infrared ray can be used. .

Since the metal heating wire such as nichrome is easy to deform plastically, the uniform heating of the planar heating element We manufacture in shape.

However, carbon fiber yarns are very high in elasticity, and thus, plastic deformation is not easy. There is a problem that it becomes difficult to arrange in shape.

Therefore, a planar heating element using a carbon fiber heating paper in which carbon fibers are dispersed in a pulp, and a planar heating element using a carbon fiber yarn woven with carbon fiber yarn, are used, rather than a far-infrared radiant planar heating element using carbon fiber yarn heating wire.

However, in order to obtain a carbon fiber heating paper and a carbon fiber yarn fabric, a paper heating element and a weaving process are required, respectively.

SUMMARY OF THE INVENTION An object of the present invention is to solve the above-described conventional problems, and to form grooves having a predetermined interval of lattice shape on the inner surface of the polymer insulating member of the planar heating element and to form a carbon fiber yarn heating wire By arranging in a desired shape as the shape, it is possible to provide a far-infrared radiating planar heating element using carbon fiber yarn heating line and to provide a far-infrared radiating planar heating element with low production cost.

To this end, in the present invention, it is possible to arrange the carbon fiber yarn in the desired shape by inserting the lattice-shaped groove portion provided on the surface of the polymer insulation member, even if the carbon fiber yarn is deformed to a certain shape even if the elasticity and the plasticity is low Ensure that the state is maintained continuously.

On the other hand, in the present invention, it is possible to configure the far-infrared radiant heating element in the state of carbon fiber yarn heating wire, so that no additional work such as papermaking process or weaving process is required, so that far-infrared radiant heating element can be manufactured at a much lower cost than before. do.

It is for arranging in a shape, and can be easily formed by heating a punch embossed in a lattice shape and pressing the polymer insulating member 12.

At this time, the distance between the lattice of the lattice groove 14 formed on the surface of the polymer insulating member 12 can be adjusted to a desired size, and the lattice shape may be applied to various forms such as rectangular as well as square.

In addition, the width of the lattice groove 14 formed in the polymer insulating member 12 is 1 to 5 mm, the depth of 0.1 to 5 mm is suitable, but the width and depth of these grooves can be adjusted to suit the purpose.

Since the bent portion 15 is formed at the corner portion of the lattice-shaped groove portion 14 formed in the polymer insulating member 12 shown in FIG. 3, the carbon fiber yarn heating wire 11 touches the edge portion and is damaged. Can be prevented.

The bent portion 15 at the edge of the lattice groove 14 of the polymer insulating member 12 can be easily solved by giving a radius of curvature to the lattice intersection of the press punch embossed in the lattice shape.

The carbon fiber yarn heating wire 11 is formed along the lattice groove 14 formed in the polymer insulating member 12. According to the width and depth of the lattice groove 14 and the thickness of the carbon fiber yarn heating wire 11 when arranged in a shape, the adhesive 61 is applied to the carbon fiber yarn heating wire 11 to the polymer insulating member 12.

In addition, as the adhesive to be applied to the carbon fiber heating wire 11, polybenzeneimidazole, silicone or polyurethane-based high temperature adhesive, which exhibits stable adhesion even at high temperatures, is most suitable, but other types of synthetic resin adhesives may be used.

The carbon fiber yarn heating wire 11 is formed along the lattice groove 14 formed in the polymer insulating member (lower portion) 12 as described above. When the polymer insulating member (upper part) 13 is laminated in a shape by laminating by hot press or hot roller operation, a far-infrared radiation surface heating element as shown in Figs. 1 and 2 is formed.

One carbon fiber yarn heating wire 11 as shown in FIG. After arranging in a shape and placing an epoxy plate having a thickness of 3 mm as the upper polymer insulating member 13 thereon, lamination was performed by a hot press operation in a temperature range of 150 to 300 ° C. to produce a planar heating element.

In addition, a 3 mm-thick urethane plate was used as the lower polymer insulating member 12.

Along the carbon fiber heating wire (11) It is also possible, of course, to use only those arranged in the desired shape, including the shape, as the far-infrared radiation plane heating element. In this case, the carbon fiber yarn heating wire 11 In order to prevent the shape from being disturbed in use, the carbon fiber heating wire 11 coated with the adhesive 61 is formed along the lattice groove 14 of the polymer insulating member 12. It should be arranged in shape.
