<First Embodiment>

1A to 1F are manufacturing process diagrams sequentially illustrating a method of manufacturing a heating device according to a first embodiment of the present invention.

First, as illustrated in FIG. 1A, a manufacturing method for manufacturing the heating device 100 according to the first embodiment of the present invention performs a material preparation step of preparing a material 102 for heat generation.

At this time, the raw material 102 is produced in a curved shape. Preferably, the raw material 102 is made into a cylinder.

Here, the material 102 is made of a transparent quartz or ceramic material having a small coefficient of thermal expansion so as to reduce the stress from the thermal shock.

Thereafter, as shown in FIG. 1B, it is positioned at both sides of the material 102, and the cover for preventing deposition 103 is inserted in both parts of the material 102.

More specifically, the deposition preventing cover 103 is formed to be fitted with the material 102, but is formed to be fitted to the position where the electrode terminal 107 to be described later will be formed.

Here, the deposition preventing cover 103 is made of a heat resistant or insulating material, preferably, the deposition preventing cover 103 is made of at least one of asbestos and ceramic materials.

In this case, the deposition preventing cover 103 is manufactured by including an asbestos material used as a heat dissipation material, a fire protection material, an insulation material, or a ceramic material having strong heat resistance even at a high temperature.

However, the present invention is not limited thereto, and both asbestos and a part of a ceramic material may be included to manufacture a cover 103 for preventing deposition while increasing insulation and being resistant to heat.

Thereafter, as shown in FIGS. 1C and 1D, a conductive film forming step of forming a conductive film 105 by depositing a conductive material on the material 102 except for the deposition preventing cover 103 is performed.

More specifically, any one or more of stannic chloride, hydrochloric acid, antimony chloride, fluorine, ammonium, and distilled water may be formed by using a nozzle means 106 on the upper portion of the material 102 except for the deposition preventing cover 103. The conductive material containing is formed by depositing in a liquid form.

However, the present invention is not limited to this, but is not shown, but using a laminating means (not shown) on the top of the material (not shown) except for the cover for deposition prevention, tin tin chloride, hydrochloric acid, antimony chloride, fluorine, ammonium It may be formed by depositing a conductive material containing any one or more of distilled water in the form of a film.

In this case, the conductive material is deposited on the material 102 that is preheated at 600 ° C. to 900 ° C. except for the deposition preventing cover 103, and is formed of the conductive film 105.

Here, the conductive film 105 is formed based on a tin compound and with other additives added thereto. In other words, the conductive film 105 is 10 to 30% by weight of ditin chloride, 8 to 18% by weight hydrochloric acid, 0.5 to 2% by weight antimony chloride, 1 to 10% by weight of fluorine, 0.2 to 1% by weight of ammonium fluoride, and The rest is made up of distilled water. At this time, the mixture is mixed and aged for about 36 hours.

When the tin tin is 30% by weight or more, hydrolysis is not performed smoothly. Therefore, after the formation of the conductive film 105, a cloudy phenomenon occurs, which reduces transparency.

In addition, when the tin tin is 30% by weight or more, the conductive film 105 is unstable, and unbalanced heat generation occurs, and the conductive film 105 is easily damaged at high temperature heat of about 300 ° C. On the other hand, when the tin tin is 10 wt% or less, the heat generation state of the conductive film 105 is insufficient.

When antimony chloride is 2% by weight or more, hydrolysis is not performed smoothly. Therefore, a cloudy phenomenon occurs after the conductive film 105 is formed, thereby reducing transparency.

In addition, when the antimony chloride is 2% by weight or more, the conductive film 105 becomes unstable and unbalanced heat generation occurs. On the other hand, when the antimony chloride is 0.5 wt% or less, the heat generation state of the conductive film 105 is insufficient.

When the fluorine is 10 wt% or more, the fluorine does not dissolve in hydrochloric acid, so that the conductive film 105 is unstable and unbalanced heat generation occurs. On the other hand, when the fluorine is 1 wt% or less, the heat generation state of the conductive film 105 is insufficient.

When the ammonium fluorine is 1% by weight or more, the fluorine ammonium is not dissolved in hydrochloric acid, so that the conductive film 105 is unstable and unbalanced heat generation occurs. On the other hand, when the ammonium fluoride is 0.2 wt% or less, the heat generation state of the conductive film 105 is insufficient.

When the hydrochloric acid is 18% by weight or more, the heat generation state of the conductive film 105 is insufficient, and when the hydrochloric acid is 8% by weight or less, hydrolysis is not performed smoothly, so that a cloudy phenomenon occurs after the conductive film 105 is formed. The transparency will be reduced.

The following experimental tables show the results of the effects of ditin and antimony chloride on the thickness of the conductive film according to the temperature characteristics and the weight% of the conductive material.

Experimental Table 1 is an experimental result table of the tin tin chloride on the thickness of the conductive film.

Test Table 2 is a test result table of antimony chloride on the thickness of the conductive film.

① Experimental material: Quartz tube 20Φ250㎜ 2t (113㎠)

② Spray time of conductive material: 2 seconds

③ Rotational speed of material: 50 RPM / min

<Experiment Table 1>

<Experiment Table 2>

As shown in Test Table 1 and Test Table 2, it can be seen that the thickness of the conductive film becomes thicker when the weight percent of ditin and antimony chloride in the conductive material increases.

Further, as shown in Test Table 1 and Test Table 2, it can be seen that as the temperature of the ditin and antimony chloride in the conductive material increases, the thickness of the conductive film becomes thicker.

Therefore, it can be seen that the relationship between the tin tin chloride and the antimony chloride increases proportionally with respect to the weight% range and the temperature range.

On the other hand, the thickness of the conductive film 105 is determined under the appropriate conditions of the material and the rotational speed, temperature, spraying time and air pressure of the material and is formed to about 100 kPa to 6000 kPa.

At this time, when the thickness of the conductive film 105 is 100 kW or less, the heat generation amount is insufficient, and when 6000 kPa or more, the heat generation amount is excessive, making it unsuitable for use as a heat generator.

In addition, the resistance value of the conductive film 105 is 5Ω to 10000Ω / cm 2 and the resistance value may be adjusted according to the applied voltage.

Therefore, the heating device should be manufactured in consideration of the heating temperature and heating area, the temperature of the material according to the applied voltage, the spraying time of the conductive material, the rotational speed of the material, and the reactivity between the material and the conductive material.

Subsequently, as shown in FIG. 1E, electrode terminal materials are deposited on both ends of the conductive film 105 by using electrode nozzle means 108 for electrodes, and baked at 650 ° C. to 700 ° C. to form electrode terminals 107. The electrode terminal forming step is performed.

However, the present invention is not limited thereto, but the electrode terminal material is deposited by laminating means (not shown) on both ends of the conductive film (not shown), and then baked at 650 ° C. to 700 ° C. to form the electrode terminal 107. ) Is performed to form an electrode terminal.

In this case, the electrode terminal material may include any one or more of silver (Ag), copper (Cu), and gold (Au) having high thermal conductivity. The electrode terminal 107 is electrically connected to a power supply unit (not shown), which will be described later, and receives a proper voltage by the power supply unit (not shown) to preheat the conductive film 105.

Finally, as shown in FIG. 1F, a drying and firing step of drying and firing the conductive film 105 and the electrode terminal 107 under appropriate conditions is performed.

As described above, since the heating device 100 sequentially manufactured uses instantaneous high temperature heating, it is possible to efficiently supply heat by supplying warm air to the inside of the material 102, which can be used as a dryer or a hot air heater, which is an industrial and home heating element.
