Problems solved by technology

[0002] At present, among metal heating wire materials, nickel-chromium wire, iron-chromium-aluminum wire, etc. are mainly used. Because of their high resistivity, in the case of equal diameter and resistance, the length of the heating wire is relatively short, so compared with surface As far as heating materials are concerned, the same amount of heat generated under the same power is relatively concentrated, and the heating area is small, or under the same heating area, the heating is uneven. Uniform, but the price is more expensive; and the price of metal heating wire is lower; in addition, the metal heating wire also has the problem of electromagnetic radiation

Embodiment Construction

[0013] Use low-resistivity steel wire (1) with small diameter and unlimited varieties as the heating element. After selecting a certain diameter and length, the entire section of steel wire (1) is folded back and arranged in an unlimited way, dense, uniform, Arranged in an orderly manner on the same plane of the set area, the heating power of the whole section of steel wire (1) is adjusted by adjusting the power supply voltage; the whole section of steel wire (1) is pre-embedded densely, uniformly and orderly In the dielectric material plate (2), it is processed and formed at one time to make a heating plate; the whole section of steel wire (1) is densely, evenly and orderly arranged between two separate dielectric material plates (2), and the three are combined The heating plate is made as a whole; the dielectric material plate (2) is made of a material with good heat conduction and good insulation; the diameter of the steel wire (1) used as the heating wire is sufficiently sm...

Abstract

The invention provides a method for adopting a linear steel wire to produce surface-type heating effect so that a heating plate which is low in cost and high in quality is acquired. The steel wire, which is low in resistivity and fine in diameter without limitation of variety, is adopted to act as a heating element. After certain diameter and length are selected, the whole segment of the steel wire is densely, evenly and orderly arranged on the same plane of a medium material plate with the preset area in a back-turning arrangement mode without limitation of mode so that the heating plate is manufactured. Size of heating power of the whole segment of the steel wire is adjusted by adopting the mode of adjusting size of power supply voltage. The manufactured heating plate has the surface-type heating effect, and is low in cost and high in quality and simple in method without radiation so that the heating plate is worth promoting.

Description

technical field [0001] The invention relates to a method for making a heating plate, which is used in the field of low-temperature heating and heating. Background technique [0002] At present, among metal heating wire materials, nickel-chromium wire, iron-chromium-aluminum wire, etc. are mainly used. Because of their high resistivity, in the case of equal diameter and resistance, the length of the heating wire is relatively short, so compared with surface As far as heating materials are concerned, the same amount of heat generated under the same power is relatively concentrated, and the heating area is small, or under the same heating area, the heating is uneven. Even, but the price is more expensive; and the price of the metal heating wire is lower; in addition, the metal heating wire also has the problem of electromagnetic radiation. Contents of the invention [0003] The present invention provides a method of using linear steel wires to produce a surface heating effec...
