Description

Technical Field

[0001] The utility model relates to the technical field of heating wires, and more specifically to a double-helix carbon fiber heating wire. Background Art

[0002] With the continuous progress of society and the continuous improvement of power facilities, the use of heating wires is becoming more and more extensive. Heating wires are wires that generate heat by the thermal effect of current after being energized. Heating wires have the characteristics of high temperature resistance, fast heating, long service life, and stable resistance. They are widely used in large and small industrial furnaces, electric heating pipes for heating and air-conditioning equipment, and the interior of various household appliances.

[0003] Most of the heating wires on the market are heated by copper wire first. When the heating wire is energized, it generates a magnetic field. These electromagnetic fields are harmful to the human body. In addition, the electric heating efficiency of copper wire is low and it cannot achieve the purpose of solving energy problems. At the same time, the copper wire is easily deformed and broken when pulled and bent, which has many disadvantages. Therefore, we provide a double-helix carbon fiber heating wire. Utility Model Content

[0004] The purpose of this utility model is to provide a double-helix carbon fiber heating wire to solve the problems raised in the above background technology:

[0005] Most of the wires on the market heat up first by heating the copper wire. When the heating wire is energized, it generates a magnetic field. These electromagnetic fields are harmful to the human body. In addition, the electric heating efficiency of the copper wire is low and it cannot achieve the purpose of solving the energy problem. At the same time, the copper wire is easily deformed and broken when pulled and bent, and there are many disadvantages.

[0006] In order to achieve the above purpose, the present invention provides the following technical solutions:

[0007] A double-helix carbon fiber heating wire comprises a first flame-retardant insulating silicone protective layer and a second flame-retardant insulating silicone protective layer, wherein the first flame-retardant insulating silicone protective layer and the second flame-retardant insulating silicone protective layer are intertwined, and a non-magnetic carbon fiber wire is inserted into the interior of the first flame-retardant insulating silicone protective layer. The non-magnetic carbon fiber wire can shield electromagnetic waves, reduce external heat and has flame retardant effects. The magnetic field generated by the non-magnetic carbon fiber wire and the magnetic field generated when the heating wire is energized can offset each other, thereby effectively preventing the harm of the electromagnetic field to the human body. The heating efficiency is higher and the energy saving is greater than that of normal copper wire. The carbon fiber material is also more resistant to tension and bending, and the overall structure is lighter, more efficient and environmentally friendly. The interior of the second flame-retardant insulating silicone protective layer is inserted with an oxygen-free tinned copper wire.

[0008] Preferably, the first flame-retardant insulating silicone protective layer and the second flame-retardant insulating silicone protective layer are both made by refining silicone blocks and additives, wherein the additives serve to harden the raw materials and prevent corrosion.

[0009] Preferably, the additives include masterbatch, defrost and vulcanizer. The first flame retardant insulating silicone protective layer and the second flame retardant insulating silicone protective layer formed by refining the masterbatch, defrost and vulcanizer in combination with silicone blocks are more durable and can increase the service life of the first flame retardant insulating silicone protective layer and the second flame retardant insulating silicone protective layer.

[0010] Preferably, the first flame-retardant insulating silicone protective layer and the second flame-retardant insulating silicone protective layer have the same specifications, and the first flame-retardant insulating silicone protective layer and the second flame-retardant insulating silicone protective layer are wound together in a double helix structure.

[0011] Preferably, the outer wall of the carbon fiber wire with no magnetic boundaries is tightly fitted with the inner wall of the first flame retardant insulating silicone protective layer, and the first flame retardant insulating silicone protective layer is wrapped around the outside of the carbon fiber wire with no magnetic boundaries. The carbon fiber wire with no magnetic boundaries is composed of multiple strands and twisted into an integrated structure.

[0012] Preferably, the outer wall of the oxygen-free tinned copper wire is tightly fitted with the inner wall of the second flame-retardant insulating silicone protective layer, and the second flame-retardant insulating silicone protective layer is coated on the outer side of the oxygen-free tinned copper wire. The oxygen-free tinned copper wire is also composed of multiple wires and twisted into an integrated structure.

[0013] Compared with the prior art, the beneficial effects of the present invention are:

[0014] Currently, most of the wires on the market are copper wire heating. The utility model uses non-magnetic boundary carbon fiber wire, which can shield electromagnetic waves, reduce external heat, and has flame retardant effects. The magnetic field generated by the non-magnetic boundary carbon fiber wire and the magnetic field generated by the heating wire after power is turned on can offset each other, thereby effectively preventing the harm of electromagnetic fields to the human body. It can also be more efficient and energy-saving than normal copper wire electric heating. The non-magnetic boundary carbon fiber wire is also more resistant to tension and bending, and is lighter, more efficient and environmentally friendly as a whole. BRIEF DESCRIPTION OF THE DRAWINGS

[0021] See also Figures 1 to 4 A double-helix carbon fiber heating wire comprises a first flame-retardant insulating silicone protective layer 1 and a second flame-retardant insulating silicone protective layer 2. The first flame-retardant insulating silicone protective layer 1 and the second flame-retardant insulating silicone protective layer 2 are intertwined with each other. A non-magnetic carbon fiber wire 3 is penetrated inside the first flame-retardant insulating silicone protective layer 1. The non-magnetic carbon fiber wire 3 can shield electromagnetic waves, reduce external heat and flame retardant effects. The magnetic field generated by the non-magnetic carbon fiber wire 3 and the magnetic field generated after the heating wire is energized can offset each other, thereby effectively preventing the harm of the electromagnetic field to the human body. The overall structure is also lighter, more efficient and environmentally friendly. An oxygen-free tinned copper wire 4 is penetrated inside the second flame-retardant insulating silicone protective layer 2.

[0023] Furthermore, the additives include masterbatch, defrost and vulcanizer. The first flame retardant insulating silicone protective layer 1 and the second flame retardant insulating silicone protective layer 2 formed by refining the masterbatch, defrost and vulcanizer in combination with the silicone block are more durable and can increase the service life of the first flame retardant insulating silicone protective layer 1 and the second flame retardant insulating silicone protective layer 2.

[0025] Furthermore, the outer wall of the carbon fiber wire 3 with no magnetic boundaries is tightly fitted with the inner wall of the first flame-retardant insulating silicone protective layer 1, and the first flame-retardant insulating silicone protective layer 1 is wrapped around the outer side of the carbon fiber wire 3 with no magnetic boundaries. The carbon fiber wire 3 with no magnetic boundaries is composed of multiple strands and twisted into an integrated structure. The carbon fiber wire with no magnetic boundaries has higher electric heating efficiency and energy saving than normal copper wire, and is also more resistant to tension and bending.

We use a non-magnetic boundary carbon fiber wire 3. Different from the ones on the market, the non-magnetic boundary carbon fiber wire 3 can shield electromagnetic waves, reduce external heat (basically no), and has flame retardant effects.
