Description

Technical Field

[0001] This utility model relates to the field of carbon nanotube technology, and in particular to an ultrathin carbon nanotube heating element. Background Technology

[0002] Ultrathin carbon nanotubes are nanomaterials with unique structures and excellent properties. Their tubular structure, composed of carbon atoms arranged in a hexagonal pattern, exhibits extremely high mechanical strength, electrical conductivity, and thermal conductivity. Ultrathin carbon nanotubes have broad application prospects in electronics, thermal management, and energy storage. Especially in heating elements, their superior electrical conductivity and lightweight properties make them ideal heating materials. By utilizing the resistance heating effect of ultrathin carbon nanotubes, heating elements can reach high temperatures in a very short time and achieve relatively uniform heat distribution, thus finding wide application in portable heating devices, smart wearable devices, and automotive and electronic products.

[0003] Existing ultrathin carbon nanotube heating elements typically use traditional threaded connections to secure the housing during installation. However, while simple to operate, traditional threaded connections lack effective positioning structures, often leading to excessive or insufficient twisting of the housing during installation. This not only affects installation accuracy but can also degrade the element's sealing performance, thus impacting heating efficiency and equipment stability. Therefore, this paper proposes an ultrathin carbon nanotube heating element to address these issues. Utility Model Content

[0004] To overcome the above shortcomings, this utility model provides an ultrathin carbon nanotube heating element, which aims to improve the problem that the traditional threaded connection in the prior art lacks a positioning structure, resulting in excessive or insufficient torsion of the shell during installation.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] An ultrathin carbon nanotube heating element includes a connector and a heating rod. A connecting seat is fixedly connected to the top of the connector. The heating rod passes through the connecting seat and is connected to the connector. A carbon nanotube shell is provided on the outside of the heating rod. A positioning mechanism is provided on the outside of the carbon nanotube shell.

[0007] The positioning mechanism includes a connecting cover with a recessed hole fixedly connected to the bottom of the connecting cover. An annular groove is opened inside the connecting seat, and a rubber block is fixedly connected inside the connecting seat. The side wall of the connecting cover is slidably connected inside the annular groove, and the rubber block is disposed inside the annular groove. The annular groove and the rubber block fit together. The carbon nanotube shell is threadedly connected to the side wall of the connecting seat.

[0008] As a further description of the above technical solution:

[0009] A sealing ring one is fixedly connected to the outer wall of the connecting cover, and a sealing ring two is fixedly connected to the inner wall of the connecting cover.

[0010] As a further description of the above technical solution:

[0011] Both the first sealing ring and the second sealing ring are attached to the top of the connecting seat.

[0012] As a further description of the above technical solution:

[0013] The carbon nanotube shell consists of a thermally conductive layer, a protective layer, and a carbon nanotube heating film from the outside to the inside.

[0014] As a further description of the above technical solution:

[0015] The thermally conductive layer is made of graphene material.

[0016] As a further description of the above technical solution:

[0017] The protective layer is made of silicon nitride.

[0018] As a further description of the above technical solution:

[0019] The top of the carbon nanotube shell is fixedly connected to a side ear.

[0020] This utility model has the following beneficial effects:

[0021] 1. In this utility model, when installing the carbon nanotube shell, it is rotated to the top of the connecting seat and the bottom of the connecting cover is slid into the annular groove. With the help of the thread, the shell gradually moves down and squeezes the rubber block until the rubber block enters the concave hole, thus completing the installation. Through the cooperation between the above structures, the shell is prevented from being over-twisted or not twisted in place.

[0022] 2. In this utility model, the thermal efficiency, durability and reliability of the heating element are improved by the cooperation between the thermal conductive layer, the protective layer and the carbon nanotube heating film. The graphene thermal conductive layer ensures rapid heat conduction, the silicon nitride protective layer provides external protection, and the carbon nanotube heating film ensures rapid and stable heating performance.

[0029] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0030] Reference Figures 1-3 This utility model provides an embodiment of an ultrathin carbon nanotube heating element, comprising a connector 1 and a heating rod 3. A connecting seat 2 is fixedly connected to the top of the connector 1. The heating rod 3 passes through the connecting seat 2 and is connected to the connector 1. The heating rod 3 is existing technology and will not be described in detail here. A carbon nanotube shell 4 covers the heating rod 3, and a positioning mechanism is provided on the outside of the carbon nanotube shell 4. The positioning mechanism includes a connecting cover 5, with a recessed hole 8 fixedly connected to the bottom of the connecting cover 5. An annular groove 9 is formed inside the connecting seat 2, and a rubber block 10 is fixedly connected inside the connecting seat 2. The sidewall of the connecting cover 5 is slidably connected to the annular groove 9. Inside, the rubber block 10 is set inside the annular groove 9, and the annular groove 9 matches the rubber block 10. The carbon nanotube shell 4 is threaded to the side wall of the connecting seat 2, making the entire heating element tighter during use and avoiding loosening. The outer wall of the connecting cover 5 is fixedly connected with a sealing ring 6, and the inner wall of the connecting cover 5 is fixedly connected with a sealing ring 7. Both the sealing ring 6 and the sealing ring 7 are attached to the top of the connecting seat 2, preventing external substances from entering the element and avoiding the corrosion of moisture, dust or other corrosive substances, thus enhancing the safety and service life of the element. The top of the carbon nanotube shell 4 is fixedly connected with a side ear 11.

[0031] After prolonged use, when the carbon nanotube shell 4 needs to be replaced, it can be rotated by turning the side lug 11. During rotation, the carbon nanotube shell 4 gradually rises along the threads and, through contact with the rubber block 10, compresses the rubber block 10, causing it to deform and disengage from the recess 8. As the carbon nanotube shell 4 rises, disassembly is completed. When installing a new carbon nanotube shell 4, align it with the top of the connecting seat 2 and rotate it to the correct position. The bottom of the connecting cover 5 slides into the annular groove 9. With the rotation caused by the threads, the carbon nanotube shell 4 gradually moves downwards, applying pressure to the rubber block 10 until it returns to the recess 8. This ensures a secure installation of the carbon nanotube shell 4, effectively preventing excessive twisting or improper installation, guaranteeing accuracy and stability, and ensuring the high efficiency of the heating element during use.

[0032] Reference Figure 4 The carbon nanotube shell 4 is provided with a thermally conductive layer 12, a protective layer 13, and a carbon nanotube heating film 14 from the outside to the inside. The carbon nanotube heating film 14 converts electrical energy into heat energy efficiently through its high electrical conductivity and excellent resistance characteristics, providing rapid heating and a long-lasting heat source. The thermally conductive layer 12 is made of graphene material, which can effectively conduct the heat generated by the heating rod 3 to the carbon nanotube shell 4, thereby improving the overall heating efficiency. The protective layer 13 is made of silicon nitride material, which can effectively protect the heating element from environmental factors such as high temperature and chemical corrosion.

[0033] Working principle: When the device is in use, when current passes through the heating rod 3, according to Ohm's law, the resistive part of the heating rod 3 will generate heat, thereby heating the surrounding environment. With the cooperation of the carbon nanotube shell 4, the heat can be evenly distributed, improving heating efficiency. After long-term use, when the carbon nanotube shell 4 needs to be replaced, it can be rotated through the side lug 11. During the rotation, the carbon nanotube shell 4 will squeeze the rubber block 10, causing it to deform and thus detach it from the concave hole 8. As the carbon nanotube shell 4 gradually rises, the disassembly is completed. When installing a new carbon nanotube shell 4, it is twisted again to the top of the connecting seat 2, and the bottom of the connecting cover 5 slides inside the annular groove 9. Under the action of the thread, the carbon nanotube shell 4 will gradually move down, gradually squeezing the rubber block 10. When the rubber block 10 is placed inside the concave hole 8, the installation of the carbon nanotube shell 4 is completed, ensuring the accuracy of the installation and avoiding over-twisting or under-twisting.

[0034] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
