1 is a diagram schematically showing a heating system using multiple heating wires according to a preferred embodiment of the present invention, and a transparent hose is removed to check the electrical connection between the heating part and the lead wire.

As shown, the heating system according to a preferred embodiment of the present invention includes at least one heating unit 1, a control unit 2 for controlling power supply to the at least one heating unit 1, a heating unit 1 and a control unit. (2) It consists of a lead wire 3 interposed so as to be able to communicate with each other, and a binding part 5 for connecting the heat generating part 1 and the lead wire 3.

The heating system using multiple heating wires according to the present invention can supply power to each heating unit 1 through the control unit 2. The control unit 2 extends the lead wires 3 connected in parallel to the outside, wherein the control unit 2 is a power supply source capable of applying a current to the heating wire bundles 11 (see Fig. 2) through the lead wires 3 would. The present invention is not limited thereto, and the heating system according to the present invention may be used by connecting one or more heating units in series. As shown, the control unit 2 draws a pair of lead wires 3 consisting of, for example, + and-poles from four channels, and connects the heating unit 1 to the end of the lead wire 3 so that it can be electrically connected. do. Accordingly, the present invention can generate heat by selectively supplying power to each lead wire 3 with a power voltage of 220V through the control unit 3 with a preset output voltage (60V to 220V). have. The heating system according to the present invention reduces the pressure to a rated voltage of about 60V, which is lower than the household voltage, in each heating unit 1, so that effects such as electric shock prevention and electricity saving can be expected. The control unit 2 may heat the four heating units 1 through four channels, but is not limited thereto and may apply current to one or more or a plurality of heating units.

The control unit 2 is designed to maintain a preset temperature, for example, by sensing the ambient temperature of the heating unit 1 and turning on/off the power supplied to the lead wire 3 wired in each channel. In addition, a display (not shown) may be installed to display the amount of voltage supplied to each channel, a set temperature, and a current heating temperature. In order to help a clear understanding of the present invention, a detailed description of the specific configuration of the control unit 2 will be excluded.

In the present invention, as described above, the outer circumferential surface of the heating unit 1 including a bundle of heating wires that generates heat according to the application of a current is coated in a waterproof processing method, so that a waterproof effect as well as a heating effect can be expected. This waterproof effect can improve the durability of the heating part 1 by preventing water from penetrating into the heating part 1 in advance.

FIG. 2 is an exploded perspective view illustrating the internal structure of the constituent members shown in FIG. 1.

The inside of the heating part 1 is composed of a winding tape 12, a first coating layer 13, and a second coating layer 14 using a bundle of heating wires 11 that generate heat by the application of electric current as a heating element as described above. do. Here, the heating wire bundle 11 may be a multiple heating wire composed of one or more carbon fiber heating wires 11a and an alloy heating wire 11b made of one or more ultrafine wires, and is a heating material that converts electrical energy into heat energy. As is widely known to those skilled in the art, the alloy heating wire can induce high temperature heat in a short time even under a low power source, and can be manufactured thinly in nano units. In contrast, the carbon fiber heating wire does not generate electromagnetic waves and can maintain a stable heating state due to a constant temperature characteristic that does not increase to a higher temperature when it reaches a certain temperature, and power use can be minimized. Specifically, the present invention can further increase the maximum heating temperature than the case of employing only the carbon fiber heating wire by combining the thin-walled alloy heating wire 11b and the carbon fiber heating wire 11a, and heating and cooling ), it provides the advantage of smoothly dissipating heat to the outside by supplementing the durability and tension of the alloy heating wire with the heating part.

Specifically, the heating unit 1 includes a bundle of heating wires 11, a conductive winding tape 12 disposed on the outer circumferential surface of the heating wire bundle 11, and a first covering layer 13 disposed on the outer circumferential surface of the winding tape 12 , And a second covering layer 14 disposed on the outer circumferential surface of the first covering layer 13, while the heating unit 1 is further provided with a transparent hose 6 around the outer circumferential surface of the second covering layer 14 as necessary. You may. Preferably, the transparent hose 6 is formed of a transparent Teflon material, the transparent hose 6 is a heating unit (1), a lead wire (3) connected to one end of the heating unit (1), and the heating unit (1) ) And the lead wire 3 are sized and shaped to accommodate a binding portion 5 (see FIG. 1) that electrically connects each other. The transparent hose 6 may be made of a transparent Teflon material in order to maintain the far-infrared wavelength emitted from the heating unit 1.

The heating wire bundle 11 may be composed of multiple heating wires combined with one or more carbon fiber heating wires 11a and one or more alloy heating wires 11b, as described above. Connected. The heating wire bundle 11 is spirally wound around the outer circumferential surface with a winding tape 12 along its longitudinal direction so that the carbon fiber heating wire 11a and the alloy heating wire 11b are in close contact with each other.

As shown, the winding tape 12 can constrain the heating wire bundle 11 so as not to be disturbed, and at the same time reduce the contact resistance present in the contact portion between the end of the heating wire bundle 11 and the end of the lead wire 3. Play a role. In general, the lead wire (pole wire) is in contact with the end of the bundle of hot wires as shown in Fig. 1 of Patent Document 1, which concentrates the current streamline only at the end to increase the contact resistance, which reduces current loss. On the other hand, it acts as a factor of unexpected local overheating and ignition. The present invention is designed in a structure capable of reducing the current loss moving the winding tape and the heating wire bundle by increasing the contact area between the heating wire bundle 11 and the winding tape 12 to minimize contact resistance. As a result, power consumption can be lowered and a power saving effect can be expected. To this end, the winding tape 12 may be manufactured by weaving copper fibers and aramid fibers. The present invention is not limited thereto, and the conductive winding tape may be laminated and arranged with a copper fiber layer on the inner peripheral surface of the base layer composed of aramid fibers. In addition, the winding tape 12 can also be produced by weaving copper fibers, aramid fibers, and heat-resistant fibers.

As described above, the winding tape 12 is made of copper fibers and aramid fibers, and thus provides the properties of copper and aramid fibers at the same time to compensate for the weakness of each composition. Copper can reduce the contact resistance existing in the contact portion between the ends of each of the heating wires 11a and 11b and the ends of the lead wires 3 and simultaneously transfer heat generated from the heating wire bundles 11 to the outside quickly. In contrast, the aramid fiber can provide heat resistance while providing low shrinkage and high strength properties even under high temperature. The winding tape overcomes the limitations of copper having ductility and brittleness due to the aramid fibers, thereby maintaining a wound state around the outer peripheral surface of the heating wire bundle 11. In addition, the winding tape can provide flexibility in terms of winding characteristics.

The heating system of the present invention may be coated with double coating layers 13 and 14 to provide a waterproof effect, an insulation effect, and the like of the heating part 1. The first coating layer 13 is coated on the outside of the winding tape 12 to protect the internal components of the heating unit, while the second coating layer 14 covers the outermost layer of the heating unit 1.

The first coating layer 13 may be made of a Teflon material capable of blocking penetration of moisture from the outside and securing heat resistance, insulation stability, and waterproofness. Additionally, the first covering layer 13 may be coated with a transparent Teflon material. The heating unit 1 may be extruded or coated with a transparent Teflon material, for example, in order to maintain the far-infrared wavelength emitted from the heating wire bundle 11.

In contrast, the second covering layer 13 may be coated with a silicone material capable of providing heat resistance and waterproofness, and the second covering layer made of silicone may serve as a buffer for an external shock and provide flexibility to the heating unit.

The heating system according to the present invention comprises the first and the first surrounding the end of the heating part 1 so that the winding tape 12 of the heating part 1 and the copper wire 31 of the lead wire 3 can be reliably electrically connected. 2 The covering layers 13 and 14 are stripped and a solder layer 4 is disposed around the outer peripheral surface of the exposed winding tape 12. In other words, in the present invention, the solder layer 4 is interposed between the winding tape 12 and the copper wire 31, and the copper wire 31 can be reliably received by the winding tape 12 of the heating unit 1 At the same time having a structure, it is possible to reduce the contact resistance by disposing a current conductor layer between them.

3 is a cross-sectional view illustrating a connection state between an end of the heating part 1 and an end of the lead wire 3.

In the present invention, the end of the heating part 1 and the end of the lead wire 3 can be stably connected through the binding part 5, and reliable watertightness at the connection part of the heating part 1 and the lead wire 3 It can secure structural stability so as not to be disconnected by providing connection strength while securing and helping mutual connection with a structure that can reduce contact resistance.

The lead wire 3 is extended in length from the control unit 2, which is a power supply source, and is electrically connected to implement the heating operation of the heating unit 1 to apply a current to the heating unit 1. The lead wire 3 may be a general electric wire, and surrounds the outer circumferential surface of the copper wire 31 having excellent conductivity with a coating layer 34.

The heating part 1 removes the second covering layer 14 and the first covering layer 13 surrounding the ends thereof to expose the winding tape 12 surrounding the heating wire bundles 11; 11a, 11b, and exposes the lead wire ( 3) In addition, the coating layer 34 surrounding the end of the copper wire 31 is removed to expose the copper wire 31. The exposed winding tape 12 is surrounded by a solder layer 4 illustrated in FIG. 2. The exposed copper wire 31 is disposed in contact with the solder layer 4 disposed on the winding tape 12, and the overlapped copper wire 31, the solder layer 4, the winding tape 12, and the hot wire An aluminum layer 51 around the bundle 11 is fixed and supported. The aluminum layer 51 is deformed into a predetermined shape through a vacuum compression method so as to be fixed and supported while applying pressure to the copper wire 31, the solder layer 4, and the winding tape 12. The aluminum layer 51 provides conductivity between the copper wire 31 and the solder layer 4, and has higher tensile strength than copper, so that flexibility can be provided to the connection portion.

The binding part 5 is the exposed copper wire 31 of the lead wire fixed by being surrounded by the aluminum layer 51, the exposed winding tape 12 of the heating part, and the connection part of the solder layer 4, respectively, of the heating part 1. 1 The same transparent Teflon coating layer 52 as the coating layer 13 is extruded or coated to finish the connection between the heating unit 1 and the lead wire 3.

In step S400, the copper wire 31 is disposed to be in contact with the outer circumferential surface of the solder layer 4 disposed at the end of the heating part 1 so that the heating part 1 and the lead wire 3 can be electrically connected. To help, the copper wire 31 is wound so as to completely surround the outer circumferential surface of the solder layer 4 so that the separation of the copper wire 31 from the solder layer 4 during a subsequent process can be prevented in advance. When winding with the copper wire 31, the solder layer 4 and the winding tape 12 are clamped to more reliably support the heat wire bundle 11.
