Description

technical field [0001] The present invention relates to a method for manufacturing a heating element, a heating element and a method for using the same, especially a method for reducing the combined resistance value by synthesizing a plurality of ultra-thin wires with a high resistance value in a parallel structure in which the entire area is in contact with each other. At the same time, the high resistance value of each ultra-thin line is maintained, thereby improving the heating efficiency of the heating element manufacturing method, the heating element and the use method thereof. Background technique [0002] An electric heating element capable of generating heat when an electric current is applied has a certain resistance value. [0003] The above-mentioned resistance converts electrical energy into heat energy by obstructing the flow of electric current and releases heat. [0004] The electric heating element as described above can be used in many types of products, bu...

AI Technical Summary

Problems solved by technology

[0006] First, the conversion of electrical energy into heat is not efficient relative to the amount of electricity consumed

[0007] Therefore, many existing electric heaters and electric heating wire products are not popular compared with other heating methods because of their excessive power consumption relative to the heat generated.

[0008] Second, there is almost no technical capability for customized production, and it is impossible to achieve multi-purpose use

[0009] Only tens of thousands to hundreds of thousands of electric heating wires (heating elements) can be customized according to specific needs or on-site requirements for development, according to their calorific value or electrical characteristics (such as voltage, current, AC use, DC use, etc.) In order to be widely applicable to all industrial fields and ensure its electrical safety, the technologies related to electric heating wires or heating elements that have been developed so far hardly have the technical capability of customized production as mentioned above

[0010] Third, electrical security is very fragile

[0011] Most of the electric heating elements (heating wires) that have been developed and circulated at present will cause the current deviation to the part with uneven resistance value due to the uneven resistance value, which will cause fire, electric shock, electric leakage and other dangers, and its performance cannot be guaranteed. electrical safety

[0012] In particular, the carbon heating element that is used in combination by mixing conductive polymer (such as carbon, etc.) powder with a liquid adhesive for ink, and then coating it on a linear or planar body, has very high electrical safety. Fragile

[0013] Fourth, the metal heating wire cannot use the characteristics of the material itself to realize the constant temperature function without a separate temperature adjustment device.

[0014] When using non-thermostatic metal heating wires as described above, if the power supply regulation device or the individual temperature regulation device fails, there is a high risk of fire.

[0015] Fifth, it is almost impossible to achieve a heating effect on a wide space, and it is impossible to achieve uniform heating in the entire space

[0020] And even if some heating elements that can release radiant heat (such as heating elements containing carbon components) are used, it is almost impossible to realize the wide space because the distance that radiant heat can radiate (the distance of far infrared rays) is relatively short. heating effect

[0021] Sixth, some heating elements that can release radiant heat (such as carbon, etc.) have no electrical stability, and because they cannot achieve high-temperature heat generation, the far-infrared rays can travel relatively short distances, thus failing to achieve a wide space heating effect

[0022] A heating element capable of releasing radiant heat that can solve the above-mentioned fifth problem is relatively dangerous because there is actually no guarantee of electrical safety, and the heating element that can emit radiant heat by containing carbon components has been developed so far. Most of the heating elements adopt the method of mixing conductive polymer powder (such as carbon, etc.) This method will fundamentally cause the uniformity of its resistance value to be much lower than that of metal heating elements (metal heating wires), and after a period of use, it will cause electrical conductivity due to the difference in expansion coefficient between the conductive powder and the adhesive. Shedding of permanent powder, and eventually lead to a very obvious change in loading (reduction of calorific value)

[0023] In addition, even if the material itself can generate far-infrared radiant heat, it will cause the problem of short propagation distance of radiant heat because the temperature of the heating element cannot be heated to a high temperature state, and ultimately lead to the inability to realize the heating effect for a wide space

[0024] In addition, the heating element is used by mixing conductive powder into a liquid adhesive to make ink and then applying it to another third object. The basic principle is to use the molecules of conductive powder when the temperature rises. The method of increasing the spacing and causing the increase of the resistance value to reduce the current value (PTC (Positive Temperature Coefficient, Positive Temperature Coefficient) principle) generates heat, so the heating element cannot be heated to a high temperature state through the automatic constant temperature function

[0025] Seventh, because it is impossible to make a heating element (heating wire) that can realize the heating function at low voltage, especially under DC low voltage conditions, it is also impossible to make a heating element (heating wire) that can be directly connected with solar power generation equipment and generate heat. )

[0026] Eighth, the efficiency of burning hot water is not high

[0027] There is no heating element technology that can use low voltage to generate high temperature heat in long electric heating wires, especially when the operating voltage is lower than 24V, it is impossible to use low voltage to generate high temperature heat

[0028] Ninth, because it has no flexibility and low tensile strength, it is easy to break, and at the same time, it is easy to harden and pulverize because of poor durability and strong oxidation, resulting in short service life, and it cannot achieve ultra-high-speed heating and ultra-high temperature heating effects
