The carbon nanotube heating element 200 provided inside the tube 100 is provided in a plate shape as shown in FIG. 3, and the detailed configuration thereof is illustrated in FIG. 4, and a manufacturing process is illustrated in FIG. 5.

The carbon nanotube heating element 200 is formed to include a conductor 210, an insulating layer 220, a pair of electrodes 230, a carbon nanotube heating layer 240, and a protective layer 250.

The conductor 210 is a portion that forms a basic body for forming the carbon nanotube heating element 200, and is formed long in the longitudinal direction in a plate shape to be provided inside the tube 100.

The carbon nanotube heating layer 240 is formed to be energized with the electrode 230 on the upper side of the insulating layer 220, and forms a thin layer by using a screen printing method, such that can be manufactured to a thin thickness In addition, the size of the entire heater can also be miniaturized.

Since the discovery of the soccer ball-shaped carbon molecule C60 (60 carbon atoms: fullerene) in 1985, many research institutes around the world have been working on synthesizing new structured carbon. Dr. Ijima, a research institute, discovered an electron microscope that coincided with a long, long, dense carbon structure in 1991, and reported it to Nature, the world's leading scientific journal. . In carbon nanotubes, one carbon atom is bonded to three other carbon atoms and forms a hexagonal honeycomb pattern. If we draw this honeycomb pattern on flat paper and roll the paper round, it becomes a nanotube structure. In other words, one nanotube has the shape of a hollow tube or cylinder. This is called nanotubes because they are extremely small, usually one nanometer (one billionth of a meter) in diameter. The honeycomb pattern on the paper is rounded to form a nanotube. Depending on the angle at which the paper is rolled, the carbon nanotube may be an electrical conductor (Armchair structure) or a semiconductor (Zigzag structure). In addition, depending on the dried form, it may be classified into single-wall nanotubes, multi-wall nanotubes, and bundle nanotubes.

These carbon nanotubes have a high length / diameter ratio, and have a very large surface area per unit area, and have a chemical stability that is physically about 100 times stronger than steel. In particular, carbon nanotubes have been reported to have a higher thermal conductivity (20 to 66 W / cm · K) than diamond (33.3 W / cm · K), which has the highest thermal conductivity at room temperature. Therefore, the thermal conductivity is tens to hundreds of times higher than that of aluminum (0.243 W / cm · K) or copper (4.01 W / cm · K) used in the heat sink.

The carbon nanotube heating layer 240 is formed by transferring the material as described above to form a layer, and generates heat when power is applied to the electrode.

The protective layer 250 is provided to surround the electrode 230 and the carbon nanotube heating layer 240 on the upper side of the insulating layer 220, such as overglaze, the carbon nanotube heating Protect layer 240.

As shown in FIG. 5, the carbon nanotube heating element 200 has an insulating layer 220, an electrode 230, a carbon nanotube heating layer 240, and a protective layer 250 on the upper side of the conductor 210. ), And then sintered to complete.

Meanwhile, in the heater 1000 using the carbon nanotube heating element of the present invention, an insulating member 110 may be further inserted between the inner wall surface of the tube 100 and the protective layer 250 of the carbon nanotube heating element 200. In this case, the insulating member 110 is preferably formed of a mica (Mica) having an insulating effect and a shock absorbing effect.

Accordingly, the heater 1000 using the carbon nanotube heating element of the present invention can quickly heat air using the carbon nanotube heating element 200, and the fins 700 are interposed between the tubes 100 and the air. It is possible to increase the heat exchange performance of the miniaturization, while being provided with a temperature switch 500 for supplying power on / off to prevent problems such as fire due to overheating in advance, and has the advantage of higher safety.
