Hereinafter, embodiments of the present invention will be described in detail with reference to the drawings.

1 and 2 show an example of the configuration of a heating wire in a heating elongate body used in the present invention. The heating wire 20 includes a conductive core 21 and a first coating layer (not shown) which is an insulator covering the outer peripheral surface of the conductive core 21 A second coating layer 24 covering the outer circumferential surface of the first coating layer 22 wound by the heating wire 23; a second coating layer 24 covering the outer circumferential surface of the first coating layer 22 wound by the heating wire 23; A shielding layer 25 covering the outer circumferential surface of the second coating layer 25 and a third covering layer 26 covering the outer circumferential surface of the shielding layer 25.

The conductive padding 21 uses a conductive metal wire such as a non-resistance copper wire. The first coating layer 22 may be formed of any one of silicone, nylon thermistor, insulated PVC, capton, enamel, nickel, and Teflon.

The heating line 23 uses a heating element that passes electricity and has a high resistance value and generates heat by itself. For example, most of the metal heating elements use nichrome wires or iron chrome wires. The nichrome wire can withstand a high temperature of about 1100 DEG C,

The roms are cheaper and are used instead of nichrome wires. In addition, iron, nickel, platinum, tungsten, and molybdenum are used for special purposes. The non-metallic heating element,

(Carborundum: hydrocarbon) heating element, which can be used at a high temperature of 1100 ° C or more because it can withstand a high temperature of about 1400 ° C. The component is mainly composed of silicon carbide (SiC), and various resistivities can be obtained depending on the mixing ratio of carbon and silicon. However, there is a drawback that it is difficult to install the terminal because the operation is difficult and complicated. In addition, the carbon heating element includes a carbon fiber yarn baked in the form of rod or barrel by applying a paste to a carbon powder.

For example, when the carbon fiber yarn is used, at least one aggregate of carbon fiber yarns is laminated so that the resistance value per 1 m is about 60 OMEGA. There are 3000 strands (130 Ω ± 5%), 6000 strands (70 ± 5%), and 12000 strands (34 ± 5%) in the currently commercialized carbon fiber. For example, when 6000 strands of a carpenter are used, only one of the carpenter aggregates (6000 strands) may be used. However, when 3000 strands of a carpenter are used, two carpenter aggregates (3000 strands) .

3, the conductive padding 21 and the heating wire 23 are connected to each other so that the conductive padding 21 and the heating wire 23 are connected to each other at the other end of the heating wire 23 And the power supply is applied to the left side. The reason for doing this is to cancel the magnetic waves generated in the conductive padding 21 and the magnetic waves generated in the heating line 23 since the electric current traveling paths of the conductive padding 21 and the heating wire 23 are opposite to each other to be.

The second coating layer 24 may be made of any one of silicone, nylon thermistor, insulated PVC, capton, enamel, nickel and Teflon, which are insulators. Here, since the second coating layer 24 is an insulator that surrounds the heating line 23, an insulator having excellent insulation characteristics and heat resistance characteristics is used. Silicon, for example, uses heat-resistant insulation such as Teflon, because it has brittle brittleness due to thermal damage to the tissue when it receives heat for a long time. The Teflon is a thermoplastic resin produced by polymerizing ethylene trifluoride, and is resistant to chemical resistance, especially to fluoric acid, and is resistant to heat and radiation, and is an excellent material as a high frequency insulating material.

The shielding layer 25 uses an electromagnetic wave absorber that blocks electromagnetic waves and does not affect the outside, or a conductive body for absorbing an electric field to convert it into electric current and then bypassing the electric current to ground. For example, the second coating layer 24 is wrapped with copper (or aluminum) braid, or is wound, or wrapped around an aluminum foil and winded. At this time, the shield layer 25 is grounded to a ground line, a separate ground plate, a frame ground, or the like.

The third coating layer 26 may be formed of any one of silicone, nylon thermistor, insulated PVC, capton, enamel, nickel, and Teflon, which are insulators. The third coating layer 26 is coated on the outermost surface with a predetermined thickness and is made of a material excellent in water resistance, heat resistance and cold resistance. Fig. 3 shows the AC power source according to Article 24 of the Electrical Equipment Standard, and shows that one side of the AC power source is grounded to the ground.

7 shows that the input side of the control board 38 is supplied with AC power in combination with a receptacle using a not shown flip and the output side of the control board 38 is connected to the first power line a and the second power line b) to the hot water pipe (12) or the heating wire (20). The heating wire 20 may be configured such that the first power line a is connected to the heating wire 23 and the second power line b is connected to the conductive padding 21. The control board 38 includes a rectifier 31 for rectifying an AC power source to DC power as shown in FIG. 7, a constant voltage isoist 32 for providing the output of the rectifier 31 as a constant voltage, and a power source for the constant voltage isher 32 Based on the sensed values of the sensor unit 35 and the sensor unit 35 formed of a thermistor or the like that recognizes the overheating of the microcomputer 33, the hot water pipe 12 or the heating wire 20, A relay 1 36 for controlling the operation of the heating wire 20, a relay 2 37 for controlling the operation of the hot water pipe 12 based on the sensing value of the sensor unit 35, And a ground line connecting the display 34 and the shielding layer 25. [

The first power source line a of the AC power source is connected to the heating wire 23 of the heating wire 20 and the second power source wire b is connected to the conductive padding 21 of the heating wire 20, do. Conversely, the first power supply line a may be connected to the conductive padding 21, and the second power supply line b may be connected to the heating line 21. The conductive padding 21 and the other end of the heating line 23 are electrically connected to each other via a control board 38.

The magnetic field generated by the current flowing through the conductive padding 21 and the magnetic field generated by the current flowing through the heating wire 23 are substantially equal to each other in the direction of the current flowing through the conductive padding 21 and the direction of the current flowing through the heating padding 23, ) Are opposite to each other in the direction of the magnetic field,

The center of the magnetic field formed on the conductive padding 21 and the center of the magnetic field formed on the heating line 23 coincide with each other. Therefore, the magnetic field formed by the conductive padding 21 and the magnetic field formed on the heating line 23 are canceled each other. In other words, it is based on the principle that the magnetic fields having the same center at the close distance and opposite in direction are canceled each other.

The electric field generated by the heating line 23 is induced by the shielding layer 25 having the earth ground potential (specifically, shielded and induced by aluminum foil and copper braiding) and is discharged to the ground (or ground) The electric field is not emitted to the outside of the heating wire 20.

1 to 3, and the hot water pipe 12 is connected to a hot water pipe through a hot water tank heated by a boiler or a separate hot water heater. The hot water pipe 20, which constitutes the heating elongate body H in the present invention, So that the description of the hot water pipe is omitted.

4 and 5, the heat exchanger according to the embodiment of the present invention includes an insert groove 42 formed on a surface of a slab bottom 1 and formed with a zigzag Pad 40;

A heating elongated body (H) which is fitted along the fitting groove (42) and which is one of a hot water pipe or a heating wire having a heat generating function and having the same outer diameter;

A heat conductive plate (60) placed on the heat insulating pad (40) in contact with the upper surface of the heating elongate body (H) to conduct heat of the heating elongate body (H); And

And a finishing upper plate (70) placed on the upper surface of the heat conduction plate (60).

As shown in Figs. 8 and 9, the fitting grooves 42 of the heat insulating pad 40 are formed such that the lateral grooves 42-1 of the depth h1 and the longitudinal grooves 42-2 of the depth h1 are spaced apart from each other by a predetermined distance And each corner of the rectangular projecting portion 45 formed on the bottom thickness h2 by the intersecting fitting groove 42 forms a curved portion 46 in which the heating elongate body H is bent without bending.

The curved groove 43 is formed to be wider in the fitting groove 42 corresponding to the curved portion 46 for each corner of the rectangular projecting portion 45.

10 is an exemplary view showing a state in which protrusions added to the rim of the heat insulating pad are assembled by connecting the heat insulating pads to each other in a continuous manner.

3 and 7, when the heating wire 20 is inserted into the fitting groove 42 and the heating wire body 20 is connected to the heating wire body 20 as shown in FIG. 3 and FIG. 7, Since the heat is rapidly conducted through the plate 60, it functions as a floor heating device having a high thermal efficiency. 5, since the vertical wall 42b and the upper space of the heating wire 20 form a stepped hole 42c, the bottomed cool air is blocked through the stepped hole 42c, 42c is overheated, the temperature rise is delayed, thereby providing an effect of preventing overheating.

Since the heating wire 20 and the hot water pipe 10 can be selected and used by matching the outer diameters of the heating wire 20 and the hot water pipe 10 to coincide with the fitting hole 42, So that it can be used for the heating wire 20 or the hot water pipe 10. Therefore, since the heat insulating pad is provided, it can be commonly used for the heating wire 20 system and the hot water pipe 10 system, which is economical.

The corner of the rectangular protrusion 45 corresponding to the intersection where the lateral groove 42a and the vertical groove 42b of the fitting groove 42 intersect the curved portion 46 constitutes the insulating pad 40 used in the present invention The heating elongate body H shown in Fig. 8 does not turn at an angle of substantially 90 degrees as it passes the curved portion 46 because the fitting groove 42 corresponding to the curved portion 46 is widened by the curved groove 43 And the curved groove 43 is additionally formed so that the bending can be performed. Therefore, even if the inventive longitudinal body H is bent at almost 90 degrees, it can be inserted into the fitting groove 42 without being bent.

In addition, since the projections protruding from the rim of the thermal pad 40 are inserted into the connection grooves of the other thermal pad 40 and assembled as shown in Fig. 10, assembly and installation are facilitated since they can be assembled without any tools.

6, the heat insulating pad 40 is formed on the upper surface of the slab bottom 1 and has a fitting groove 42 in a zigzag shape, ;

A heating elongated body (H) which is fitted along the fitting groove (42) and which is one of a hot water pipe or a heating wire having a heat generating function and having the same outer diameter;

And a finishing upper plate (70) placed on the upper surface of the heat conduction plate (60).

Another example of the present invention constructed as described above is such that the heating elongated body H constituting the hot water pipe 10 or the heating wire 20 is inserted into the fitting groove 42. In the case of the heating wire 20, As shown in Fig. 7, the connection is made via the control board 38. Fig.

Then, the strip-shaped thermal diffusion plate 50 is joined to cover the upper surface of the heating wire 20 and the upper surface of the heat-insulating pad 40 at the rim portion of the fitting groove 42. The thermal diffusion plate 50 may be made of a material such as copper or aluminum having a high thermal conductivity.

The heat generated in the heating elongate body H is transferred to the heat conductive plate 50 through the thermal diffusion plate 50 because the air between the heating plate 50 and the heat conductive plate 60 forms the air- It is conducted. In this case, since the air hole 50 is formed between the thermal diffusion plate 50 and the heat conduction plate 60, the air hole 52 forms an air layer, and the heat insulating pad 40, the slab bottom 1, Thereby preventing the cool air from being directly transferred to the heat conduction plate 60, thereby increasing the thermal efficiency. In addition, since the air-tightening holes 52 are mutually connected, it provides a cooling effect at the time of overheating of the heating elongated body H, thereby contributing to prevention of overheating. The sensor 35 shown in Fig. 7 is operated when the motor 34 is overheated, and the sensor 35 is operated by the microcomputer 33 to drive the relay 1 36 or the relay 2 37 which cuts off the driving power to the heating elongate body H. So that the power supply is interrupted to stably prevent overheating.

In the present invention, when a heat-resistant adhesive layer is added to the contact area between the thermal diffusion plate 50 and the heating elongate body H and the heat insulating pad 40, initial bonding is facilitated and the heating elongate body H is prevented from being displaced . In addition, even when the heating elongated body H has an outer diameter smaller than that of the fitting groove 42 of the heating elongate body H, adhesion is maintained by the contact force of the thermal diffusion plate 50 to enable heat conduction. In this case, the heat-insulating pad 40 is realized in the state of FIG. 8 to FIG. 10, so that it is easy to install and assemble without a separate tool, and the heat-generating long body is bent at 90 degrees to fit into the fitting groove, There is an advantage.
