Description

Technical Field

[0001] The utility model relates to the technical field of heating tubes, in particular to a graphene heating tube. Background Art

[0002] With the development of society, there are many electric heating methods, which are widely used in various scenarios. Among them, the most widely used are the following three: electromagnetic heating, resistance wire heating, and microwave heating.

[0003] Analysis of the advantages and disadvantages of the three methods:

[0004] 1. Electromagnetic heating has the advantages of high heat conversion efficiency, cleanliness, hygiene, and precise control, but it also faces disadvantages such as high power, high equipment cost, restrictions on heating objects (especially ceramics), and potential radiation damage to humans caused by electromagnetic waves.

[0005] 2. Resistance wire heating has the advantages of low production cost, high stability and simple structure, but it also faces disadvantages such as high energy consumption, short service life, slow heating speed, large heating inertia and difficulty in precise control.

[0006] 3. Microwave heating has advantages such as fast speed and environmental protection, but it also faces common disadvantages such as high power consumption and uneven heating.

[0007] To sum up, the three common heating methods all have adverse factors such as high energy consumption, heating limitations, and potential radiation risks. It is necessary to design a heating component that can solve the above disadvantages. Utility Model Content

[0008] The purpose of the utility model is to provide a graphene heating tube in view of the defects and shortcomings of the prior art.

[0009] To achieve the above-mentioned purpose, the technical solution adopted by the utility model is: a graphene heating tube, the innovation of which is: comprising copper wire, terminal blocks, a graphene heating core, a quartz glass tube and a silicone sheath; the terminal blocks are pressed at both ends of the graphene heating core; the copper wire is pressed at the other end of the terminal blocks; after the terminal blocks, copper wire and graphene heating core are assembled, they are placed in a quartz glass tube; the two ends of the quartz glass tube are pressed and sealed at high temperature to form a pressed end face, and inert gas is added to the quartz glass tube; the bottom of the silicone sheath faces the graphene heating core until the pressed end face of the quartz glass tube is in contact with the root of the silicone sheath notch, and is penetrated by the copper wire to form a copper wire electrode.

[0010] Furthermore, the quartz glass tube includes a straight line, a U-shape and a ring shape, and the graphene heating core also includes a straight line, a U-shape and a ring shape, so the graphene heating tube also includes a straight line, a U-shape and a ring shape.

[0011] Furthermore, the graphene heating core is a continuous S-shaped structure.

[0012] After adopting the above structure, the utility model has the following beneficial effects:

[0013] 1. The utility model utilizes the characteristics of graphene such as rapid heating, efficient heat conduction, energy saving, environmental protection and pollution-free, long service life and unique far infrared, which better solves the problems and troubles faced by traditional heating methods.

[0014] 2. Stable power: Graphene has a unique hexagonal structure and a very small thermal expansion coefficient, which makes its physical properties very stable. During the entire experimental process, the feedback of the heating performance is very stable, ensuring that the power of the entire graphene heating tube is very stable. It has a stability that traditional resistance wires and electromagnetic heating cannot match.

[0015] 3. High thermal conductivity efficiency: The core component of the graphene heating tube, the graphene heating core, carries the excellent electrical and thermal conductivity of graphene; the thermal conductivity coefficient is as high as 3000W (mk), which is 5 times that of copper. Therefore, it can convert and transport heat energy as quickly as possible, achieving thermal conduction efficiency that exceeds any other heating method; taking a 500W graphene heating tube as an example, the glass tube temperature can be heated to above 580°C within 3 seconds.

[0016] 4. Unique far-infrared characteristics: The utility model uses graphene with excellent far-infrared characteristics and can also be applied to medical devices. The graphene heating tube can generate infrared light between 5 and 20 microns. This light can penetrate human skin and directly act on subcutaneous tissue, thereby producing some physiological effects, such as promoting blood circulation, reducing fatigue, relieving pain, etc. Graphene can generate radiation in the far-infrared band, and the radiation intensity is much higher than that of ordinary materials, so it can be used in the field of far-infrared health care.

[0017] 5. Long service life: The graphene heating core in the graphene heating tube runs smoothly under the protection of inert gas, and the power is stable, which prolongs the service life of the graphene heating tube; the service life is at least 1 times longer than that of ordinary resistance wire heating tubes / components.

[0018] 6. Low manufacturing cost: Compared with traditional electromagnetic heating and microwave heating, the structure of graphene heating lamp is relatively simple, and the manufacturing cost of each component is very low. It does not require more complex mechanical equipment. Therefore, its comprehensive manufacturing cost is almost negligible compared with other heating methods. According to incomplete calculations, the manufacturing cost of graphene heating tubes of the same power is 1 / 2 of the manufacturing cost of resistance wire, 1 / 10 of electromagnetic heating, and 1 / 5 of microwave heating.

[0019] 7. Green and environmentally friendly: Graphene heating tubes are composed of conventional parts, and the main component of the graphene heating core is carbon, so it realizes the pure conversion of electrical energy into thermal energy, and does not produce radiation risks like microwave heating and electromagnetic heating.
