Therefore, the ordered carbon nanotube film has a certain flexibility, can be bent and folded into an arbitrary shape without cracking, and the electrode 260 using the ordered carbon nanotube film has a long service life. Φ [0017] The ordered carbon nanotube film is obtained by further processing the carbon nanotube array, so the length is not limited, and the width and the size of the substrate on which the carbon nanotube array is grown may be related to actual needs. be made of. 01厘米至10厘米的厚度。 The thickness of the 0. 01 cm ~ 10 cm, the thickness of 0. 01 cm ~ 10 cm, the thickness of the ordered carbon nanotube film. 01 micron to 100 micron. The thickness of the ordered carbon nanotube film is preferably from 0.1 μm to 10 μm. [0018] In addition, the ordered carbon nanotube film may further include a plurality of long carbon nanotubes arranged in parallel.

Since the long carbon nanotube is a single carbon nanotube, its electrical resistance is smaller. Therefore, the ordered carbon nanotube film is disposed on the surface of the reflective layer 210 or the heating layer 204 as the electrode 206, which can conduct current more effectively and reduce the loss of electric energy. [0019] When the carbon nanotube structure comprises at least two layers of ordered carbon nanotube films disposed one on top of the other, the adjacent ordered carbon nanotube films are tightly bonded by van der Waals forces. Further, the number of layers of the ordered nano-carbon tube film in the carbon nanotube structure is not limited, and the adjacent two layers of ordered carbon nanotube film have a crossing angle of α90 degrees, which may be according to actual needs. _ Seek preparation. Since the carbon nanotubes in the ordered carbon nanotube film are aligned in the same direction, they have excellent electrical conductivity in the direction in which the carbon nanotubes are arranged. In this embodiment, the carbon nanotube structure can be made to have excellent electrical conductivity in all directions by changing the crossing angle α between adjacent two ordered ordered carbon nanotube films. In this embodiment, preferably, the intersection angle α=90 degrees 〇[0020] When the carbon nanotube structure includes at least one nano carbon tube long line, the nano carbon tube long line is wound around the reflective layer 210 or the heating layer 204. surface. The long line of the carbon nanotubes can be obtained by directly stretching a carbon nanotube array or stretching a carbon nanotube array and then twisting and spinning.

On October 17th, Shuttle is replacing the page tube. The carbon nanotubes have a length of 200 to 900 microns. Therefore, the long carbon nanotube line has a certain flexibility. [0021] The carbon nanotube structure may further include a plurality of carbon nanotube long lines, and a plurality of carbon nanotube long lines intersect and overlap the surface of the heating layer 204. The length, width and thickness of the carbon nanotube structure are not limited, and can be prepared according to actual needs. Since the long carbon nanotube has a certain flexibility, the carbon nanotube structure can be bent and folded into any shape without rupture. [0022] Since the carbon nanotubes in the long line of the carbon nanotubes are arranged along the length of the long line of the carbon nanotubes, the long carbon nanotubes have a small electrical resistance along the length direction. Therefore, the long carbon wire of the nano carbon tube is wound around the surface of the heating layer 204 to form an electrode 206, which can effectively conduct current and save electrical energy. [0023] When only one electrode 206 includes a carbon nanotube structure, the other electrode 206 is a metal sheet metal wire, a metal film or a conductive adhesive layer or the like.

The angle of intersection between the carbon tube films is 90 degrees. The ordered carbon nanotube film in the carbon nanotube structure has a length of 1 cm, a width of 1 cm, and a thickness of 30 μm. In this embodiment, two of the above-mentioned carbon nanotube structures are separately wrapped around the surface of the heating layer 204. Due to the good electrical conductivity of the carbon nanotube structure, a good electrical connection is made between the carbon nanotube structure and the heating layer 204. [0024] In this embodiment, the heating layer 204 is a carbon nanotube layer. Both electrodes 206 are formed by overlapping and intersecting 10 layers of ordered carbon nanotube film, and the angle between the adjacent two layers of ordered carbon nanotube film is 90 degrees.

The thickness of the insulating protective layer 208 is not limited and may be selected according to actual conditions. 5〜2毫米。 The thickness of the material is 0. 5~2 mm. The insulating protective layer 208 can be formed on the surface of the heating layer 204 by a coating or wrapping method. The insulating protective layer 208 is used to prevent the line heat source 20 from making electrical contact with the outside when in use, and also prevents the carbon nanotube layer in the heating layer 204 from adsorbing foreign impurities. The insulating protective layer 208 is an optional structure. When the line heat source 20 is in use, it can be placed on the surface of the object to be heated or spaced from the object to be heated, and can be heated by the heat radiation. Alternatively, a plurality of the line heat sources 20 may be arranged for use in various predetermined patterns. The line heat source 20 can be widely used in the fields of electric heaters, infrared therapeutic devices, electric heaters and the like. [0027] The line heat source 20 has the following advantages: First, the carbon nanotube has a lower electrical resistivity, so that the resistance of the electrode 206 is small, which is conducive to saving electrical energy. Secondly, the excellent mechanical properties of the carbon nanotubes make the carbon nanotube structure have good flexibility and mechanical strength. Therefore, the use of a carbon nanotube structure as the electrode 206 can correspondingly improve the line heat source 20, especially The durability of the flexible wire heat source 20 is such that the wire heat source 20 has a long service life; thirdly, the carbon nanotube has a low density, so the wire heat source 20 is light in weight and convenient to use. Fourth, the heating layer 204 adopts a carbon nanotube layer, and the carbon nanotube layer has a high electrothermal conversion efficiency. Fifthly, the heating layer 204 adopts a carbon nanotube layer, and the electrode 206 adopts a carbon nanotube structure, which can reduce the heating layer 204 and the electrode 206 by 1013396804-0 097128281^ single number A0101 page 10 / total 23 pages 1380734 ιοί The ohmic contact resistance between the years ι〇月 i7i improves the utilization of electric energy. [0028] In addition, in the embodiment, since the carbon nanotube has a diameter of a nanometer, the prepared carbon nanotube structure can have a small thickness, so a microwire can be prepared by using a small diameter linear substrate. Heat source. The carbon nanotubes have strong corrosion resistance, making them work in an acidic environment. Moreover, the carbon nanotubes have extremely strong stability, and even if they work in a vacuum environment of 300 or higher temperature, they do not decompose, so that the line heat source 20 is suitable for working under vacuum high temperature. The volume of the steel is 1 times higher than the weight, but the weight is only 1/6'. Therefore, the line heat source 20 using the carbon nanotubes has a higher strength and lighter weight.
