Abstract

The utility model discloses an electric heating tube with strong anti-bending capacity. The electric heating tube comprises electrodes, a tubular shell, insulators and a heating element, wherein the heating element is positioned inside the tubular shell, and two ends of the heating element are connected with the electrodes; the two ends of the tubular shell are sealed by the insulators; the heating element is a cylindrical tubular body woven from a basalt fiber and a carbon fiber; and the basalt fiber plays a role in insulation and protection of the carbon fiber. In the way, the electric heating tube with stronger anti-bending capacity not only has the functional characteristic of electro-thermal effect, but also has high tensile strength and low percentage elongation, so that the anti-bending capacity of the carbon fiber is improved and the service life of the carbon fiber heating element is prolonged; moreover, because of the addition of the basalt fiber, high temperature resistance performance of the carbon fiber is improved; and the electric heating tube with strong anti-bending capacity has the advantages of safety, reliability and good durability.

Description

The electrothermal tube that a kind of flexural capacity is stronger

Technical field

The utility model relates to the electrical heating elements field, particularly relates to the stronger electrothermal tube of a kind of flexural capacity.

Background technology

The electrothermal tube of existing employing nonmetal heating unit uses carbon fiber as heater usually; The carbon fiber heating pipe is a kind of black body material; Therefore have characteristics such as heat up rapidly, thermo-lag is little, heating is even, radiant heat transfer distance, rate of heat exchange are fast; It is a kind of a kind of high-tech product heating element that after traditional heat-generating pipes such as metal tube, quartz ampoule, halide torch, earthenware, had just risen over the past two years; Luminous flux is far smaller than the electrothermal tube of metallic heating body in the course of work, and electric conversion efficiency is up to more than 98%.Programming rate is very fast after the opening power, and body has felt hot in the time of 1 ~ 2 second, 5 second surface temperature can reach the 300-700 degree.

The energy radiation pattern of carbon fiber electric heating tube is to be main with far infrared radiation, and the far infrared wavelength that it is launched is between 8 μ m ~ 14 μ m, and the far infrared line spectrum of this section wavelength is called as " light of life ", accounts for more than 80% of whole wavelength.It can be absorbed by airborne hydrone and produce resonance frictional heat effect simultaneously, has realized the effect of quick raising heating ambient temperature.Particularly effectively the activating human body histocyte, stimulate circulation, quicken new metabolism, enhance immunity ability; Also have effects such as deodorization dehumidifying is antibiotic simultaneously; When carbon fiber electric heating tube heats, can produce the infrared radiation of 765.9W/M, be equivalent to a spectral physiotherapy appearance.If can significantly be alleviated and remission effect after often using by the people of arthritis or the puzzlement of other rheumatisms for a long time.

Carbon fiber stone heat pipe; Its life-span (continuity point burning) >=more than 6000 hours; Frequent starting, close and long-term continuous operation in, heater non-oxidation and punch-through, generate heat photochromic evenly, tube wall is inside and outside cleans; Different with metallic heating body, it has avoided the generation of electromagnetic field fully.

But because carbon fiber itself is a kind of fragile material, be prone to phenomenon of rupture, and can't repair basically after the damage, can only change.

The utility model content

The technical problem that the utility model mainly solves provides the stronger electrothermal tube of a kind of flexural capacity, shortcoming such as can not repair after can solving the easy fracture of carbon fiber own, damage.

For solving the problems of the technologies described above; The technical scheme that the utility model adopts is: provide a kind of flexural capacity stronger electrothermal tube; Comprise: electrode, tubular shell, insulator and heater; Said heater is positioned at tubular shell and two ends connection electrode, insulated body sealing around the said tubular shell, and said heater is the cylindrical tubular body that is become with carbon fiber knit by basalt fibre.

In preferred embodiment of the utility model, said tubular shell is quartz glass or ceramic shell.

In preferred embodiment of the utility model, said insulator is silicone insulation body or ceramics insulator.

In preferred embodiment of the utility model, said electricity level adopts the sheet metal and the outside to connect power lead.

The beneficial effect of the utility model is: the functional characteristic that the electrothermal tube that a kind of flexural capacity of the utility model is stronger (1) not only has electrocaloric effect; And itself have advantages of higher tensile strength and a lower elongation; The flexural capacity of enhanced carbon fiber, the useful life of prolongation carbon fiber exothermic part; (2) because the interpolation of basalt fibre, strengthened the resistance to elevated temperatures of carbon fiber, have advantages such as safe and reliable, good endurance.
