Hereinafter, exemplary embodiments of the present invention will be described in detail with reference to the accompanying drawings. In addition, the embodiments of the present invention are provided to more fully explain the present invention to those skilled in the art, the following examples may be modified in various other forms, the scope of the present invention Is not limited to the following examples.

1 is a block diagram showing a heating mat of the DC power supply method using a carbon nanotube seal according to an embodiment of the present invention.

As shown in Figure 1, the heating mat of the DC power system using a carbon nanotube seal according to an embodiment of the present invention to control the size of the DC power supply of the DC power supply device 11, DC power supply device 11 It may include an output control device 12, and a mat (15) supplied with a DC power from the DC power supply (11).

The DC power supply device 11 may be formed of a primary battery or a secondary battery that receives an AC power from the outside and converts the DC power or provides a DC power. Accordingly, the DC power supply 11 converts external AC power into DC power and supplies the carbon nanotube seal 14 of the mat 15 to the carbon nanotube chamber 14, or is formed of a primary battery such as a dry battery or a secondary battery such as a storage battery. DC power can be supplied directly to the tube chamber 14.

The output control device 12 adjusts the size of the DC power supplied from the DC power supply 11, for example, voltage or current, to adjust the heating temperature of the mat 15. To this end, the output control device 12 may be provided such that the temperature control switch for controlling the strength of the DC power supplied from the DC power supply 11 to the mat 15 is exposed to the outside.

On the other hand, the DC power supply 11 and the output control device 12 has a configuration that is separated as in this embodiment, so that the output control device 12 is supplied with DC power from the DC power supply 11 to the mat 15 It can be installed on the power cable or made of a single piece to be electrically connected to the mat 15 through the power cable.

The mat 15 is fixed so that the carbon nanotube seal 14 connected to supply the DC power from the DC power supply 11 is distributed to the fabric 13 by stitching, and dissipates the heat of the carbon nanotube seal 14. To be dispersed by (13). Here, the fabric 13 may be made of a single layer or a plurality of layers of various fibers, or a heat insulating material may be provided inside.

Meanwhile, the mat 15 may be provided with an adapter (not shown) for connecting the carbon nanotube seal 14 to a power cable at one side, where the adapter (not shown) may be detachably connected to the power cable. Can be.

The mat 15 is leaked at regular intervals so that the carbon nanotube seal 14 on the fabric 13, for example, to obtain a sufficient heating effect, the carbon nanotube seal 14 is directly or via a copper wire It may be connected to the output control device 12, it may be connected to the DC power supply device 11 through the carbon nanotube seal 14 or the copper wire from the output control device 12.

As shown in FIG. 2, the carbon nanotube seal 14 of the heating mat of the DC power supply method using the carbon nanotube seal according to the embodiment of the present invention may be made of carbon nanotubes (Carbon-Nanotube: CNF). Can be.

The carbon nanotube seal 14 is a method of creating a condition in which carbon nanotubes can be generated during the cooling process after vaporizing solid carbon such as graphite, and arc discharge, laser, etc. to vaporize the solid carbon. This method is used, but the method used here is a gaseous carbon compound containing carbon such as C 2 H 2 , CH 4 , C 2 H 4 , C 2 H 6 , CO at 500 ~ 1,500 ℃ Carbon nanotubes with a thickness of less than 0.5 ~ 30nm made by extracting carbon nanotubes by reacting with catalytic metals such as Ni, Co, Fe, Si, SiO 2, etc. are used. Used as a heating material.

In addition, the carbon nanotube seal 14 may have a length of 0.5m to 50m, in which case the heat generation amount is insufficient when less than 0.5m, it may be difficult to use because the heat generation amount exceeds 50m.

Carbon nanotube seal 14 made of carbon nanotubes according to an embodiment of the present invention is a carbon nanotube monolith, or Pt, Au, Ag, Cu, Cr, Ni, Al, Co, Fe, Si, SiO 2 , ITO, IGO, AGO, sulfur compounds, conductive polymers may be made of carbon yarn made of any one or a mixture thereof.

According to the present invention, the thermal conductivity may vary depending on the thickness and the amount of the carbon nanotube seal 14. Therefore, since the thermal conductivity varies depending on the thickness and the amount of use of the carbon nanotube seal 14, the carbon nanotube seal 14 is made to have an appropriate thickness based on the data, and an appropriate amount of carbon nanotube seal 14 is used. It is important.

The thickness of the carbon nanotube seal 14 may be changed in the heating mat of the DC power supply method using the carbon nanotube seal according to the embodiment of the present invention. By varying the thickness of the carbon nanotube seal 14 to 0.01 ~ 1mm, it is possible to increase the electrical conductivity and heat generating efficiency to obtain a heating effect of thinner, lighter and more comfortable than conventional heating material. That is, in the case of a heating mat generally used, when the thickness of the carbon nanotube seal 14 is less than 0.01 mm, it is difficult to expect a heating effect for the user, and when the thickness of the carbon nanotube seal 14 exceeds 1 mm It can be uneconomical for consumption.

In addition, the carbon nanotube thread 14 may be used as a thread for quilting one strand on a mat, but may be used as a thread by making dozens to hundreds of strands, for example, 30 to 300 strands, twisted as needed. .

The operation of the heating mat of the DC power supply method using a carbon nanotube seal according to an embodiment of the present invention having such a configuration will be described.

The data shown in Table 1 below is an experimental result showing the temperature effect appearing on the mat by use time when supplying a DC current using a 24V 2.5A adapter to a DC power heating mat using a carbon nanotube seal according to the present invention. It can be seen that using a carbon nanotube seal of less than 10m and using a low voltage direct current that generates little electromagnetic waves exhibits sufficient heat generation effect.

division 20 minutes 60 minutes normally 24 ℃ 24 ℃ 10-20W (1 phase) 25 ℃ 25 ℃ 20 ~ 30W (2 levels) 27 ℃ 30 ℃ 30 ~ 40W (3 steps) 28 ℃ 40 ℃ 40-50W (4 phases) 37 ℃ 50 ℃ 50 ~ 60W (5 steps) 42 ℃ 60 ° C

In addition, all of the conventional heating mat is made of a material such as a planar heating element such as copper wire, water or copper thin film, carbon fiber, and the like, since the heat generation efficiency is relatively low when using these materials, the conventional heating mat configured as described above It is difficult to use, store and wash by stacking thick cotton and multiple layers of fabric to protect the material or to be uncomfortable to the human body. There are several problems, such as being exposed. However, the heating mat of the DC power supply method using the carbon nanotube seal according to the present invention obtains sufficient heat generating effect by using a special material called carbon nanotubes, which has better electrical conductivity than copper and has better thermal conductivity than diamond. Positive power supply, a direct current power supply, is also possible, resulting in a breakthrough in heating devices.

In addition, as shown in Figure 3, when looking at the results of the human thermal imaging experiments of the Far Infrared Association for the heating mat of the DC power system using the carbon nanotube seal according to the present invention, it can be seen that it affects the human body temperature change evenly. . That is, the upper body temperature before use is about 33 ~ 36 ℃ at 25 ℃ room temperature, the upper body temperature after using the DC power heating mat of 10 minutes using a carbon nanotube seal according to the present invention to 38 ~ 40 ℃ Far-infrared rays are transmitted evenly to the body, and the temperature of the body can be seen to increase.

In addition, according to the heating mat of the DC power supply method using the carbon nanotube seal according to the present invention, by coating the conventional carbon on various fibers or cotton in the form of ink to weave in the form of cloth to use a high voltage such as 220V By using carbon nanotube yarn 14, which is far superior to the inefficient method and has a much higher thermal conductivity, sufficient heat of 40 ° C. to 80 ° C. is simply quilted at regular intervals on a thermal pad such as various kinds of cotton. Generate. The amount of the carbon nanotube seal 14 used is sufficient to obtain the above-mentioned exothermic effect even when the amount is less than 10 meters. In other words, it is possible to make a heating mat in a simple manner by simply squeezing a small amount of carbon nanotube thread 14 on a thin mat made of a cotton-like material that maintains warmth, and other heating sheet, heating clothing, heating sheet, It can be applied to various places such as heating wallpaper, heating sleeping bag, heating tent, heating shoes, heating gloves, heating insulation bag, heating insulation box, heating thermos, etc. It is convenient to use, store and wash and supply DC power such as adapter under 24V. By choosing the method, the electricity cost is significantly reduced, and the electromagnetic wave is rarely generated. For example, in the case of the existing carbon coated fiber, if the electricity bill of 5,000 won per month used for 8 hours a day, the carbon nanotube yarn heating mat consumes only about 1,000 electricity per month for the same time.

As described above, the present invention has been described with reference to the accompanying drawings, but various modifications and changes can be made without departing from the spirit of the present invention. Therefore, the scope of the present invention should not be limited to the described embodiments, but should be determined by the equivalents of the claims, as well as the following claims.
