DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS Hereinafter, exemplary embodiments of the present invention will be described in detail with reference to the accompanying drawings. In the following description, well-known functions or constructions are not described in detail since they would obscure the invention in unnecessary detail.

FIG. 1 is a perspective view of a heating block applied to an induction heating type heating system according to an embodiment of the present invention. FIG. 2 is a sectional view taken along the line AA of FIG. 1, and FIG.

The induction heating type heating system according to an embodiment of the present invention has a structure in which a plurality of heat pipes can be individually mounted in a plurality of installation grooves in which coils are wound, and one side of the mounted heat pipe is heated according to the induction heating principle And heat is transferred to the other side so that the entire heat pipe can be heated.

The induction heating type heating system according to the present embodiment includes a plurality of heating blocks 1 having a structure connectable to each other.

The heating block 1 includes a main body 10 and a plurality of heat pipes 100.

The main body 10 has a rectangular block shape having four sides in the front, rear, left and right directions. On the left and right side surfaces of the main body 10, a plurality of installation grooves 20, in which the heat pipes 100 can be installed, are formed.

The plurality of installation grooves 20 may be arranged at regular intervals on the horizontal line of the side surface. The quantity of the mounting grooves 20 can be varied as needed. The mounting groove 20 may be formed on only one side of the left side surface or the right side surface.

A coil (25) is wound around the mounting groove (20). 3, one side of the heat pipe 100 (for example, an induction cap 120 to be described later) is inserted into the coil 25, as shown in FIG. 3, when one side of the heat pipe 100 is inserted into the installation groove 20 It is possible to exhibit the same effect as that of being wound by the coil.

The heat pipe 100 is a heat transport device having a thermal conductivity tens or hundreds of times larger than that of the high heat conductive metal.

The heat pipe 100 basically includes a housing 110. The housing 110 is made of a gas-tight solid material such as stainless steel, copper, aluminum or the like, and may have a tubular shape having a closed space in which the interior is empty. Although the housing 110 is illustrated as being circular in cross section in the drawings, it is to be understood that this is merely one embodiment, and its cross section may have various shapes such as polygonal, elliptical, and the like.

In the housing 110, a working fluid for transferring the heat generated from one side to the other side may be injected. When heat is applied from one side of the housing 110, the working fluid evaporates in the internal space of the heating section, and the evaporated steam rapidly moves to the other side not subjected to heat and is condensed so that latent heat of the fluid is transported from the heating section to the condensation section Function. The condensed liquid is returned to the heating section by the capillary force by the wick structure provided inside the housing.

The production of such a heat pipe 100 can be carried out as follows. An injecting step of injecting a working fluid into the housing 110 through the main inlet and a partial pressing of the main inlet of the housing 110 to discharge the working fluid in the form of mist through the main inlet when the working fluid is heated A degassing step of removing foreign substances including non-condensed gas generated in the housing 110 together with a working fluid discharged through a main inlet by heating the housing 110; And a sealing step for sealing. It is possible to prevent the working fluid passing through the partially squeezed portion from being lost in the form of a liquid lump while maintaining the passage cross-sectional area of the partial squeeze portion at an appropriate size, thus completing the production of the heat pipe 100 efficiently.

In addition, the heat pipe 100 according to the present embodiment may further include an induction cap 120 in addition to the housing 110. The induction cap 120 may be mounted on one side of the housing 110, i.e., a heating portion.

The induction cap 120 may be made of a material that induces a secondary current well by electromagnetic induction. For example, the induction cap 120 may be made of a metal, an electric conductor such as carbon, silicon (silicon), germanium, Arsenic, fused silica, or the like.

When a current flows through the coil 25, a secondary current flows through the induction cap 120 due to the electromagnetic induction phenomenon, so that one side of the housing 110, that is, the heating portion, can be heated. When the heating unit is heated, the inside of the heat pipe 100 can be heated by allowing the internal working fluid to evaporate, move, and condense so that heat is transferred to the other side of the housing 110, that is, the condensing unit.

The main body 10 is formed with a main wiring 30 extending in the longitudinal direction so as to extend from the front side to the rear side. The main wiring 30 may have a pair of wire structures having (+) and (-) poles.

The branch wiring 40 is branched from the main wiring 30 and connected to both ends of an arbitrary coil 25. [ The current supplied through the main wiring 30 is supplied to each of the coils 25 through the branch wiring 40. The branch wiring 40 may also have a pair of wire structures.

The current supplied to the coil 25 is supplied to the one end of the heat pipe 100 located in the coil 25 So that Joule's heat is generated at one end of the heat pipe 100 and the entire heat pipe 100 is heated. In this case, the coil 25 becomes a heating coil and one end of the heat pipe 100 becomes a material to be heated.

A male connector 50 may protrude from one of the front and rear sides of the heating block 1 and an inner female connector 55 may be provided to the other. The male connector 50 and the female connector 55 are electrically connected through the main wiring 30.

Here, the female connector 55 and the male connector 50 have a structure corresponding to each other. Therefore, when the male connector 50 of the arbitrary heating block 1a is fitted into the female connector 55 of the adjacent heating block 1b, the two heating blocks are assembled to each other and the main wiring of the two heating blocks 30) can be electrically connected (see Fig. 2).

That is, by continuously assembling the heating block 1, it becomes possible to secure a main wiring having a desired length. This is because it is possible to secure the main wiring having a length suitable for the construction area by adjusting the number of the heating blocks 1 to be assembled according to the construction area after manufacturing a plurality of standardized heating blocks 1, do. In other words, it is not necessary to separately produce heating blocks having various sizes according to various construction areas, and it is sufficient to manufacture and assemble standardized heating blocks by unit size, so that the manufacturing cost of heating blocks can be lowered, There is an advantage that it can be secured.

A controller (5) can be installed at the foremost or the last room of the continuously assembled heating blocks. The end of the controller 5 is composed of a male connector 50 or a female connector 55 and can be electrically connected while being fastened to the heating block 1. Although the figure shows the case where the male connector 50 is provided at the end of the controller 5, this is merely an example, and it goes without saying that the female connector 55 may be provided.

The controller 5 controls the supply of current through the main wiring 30. Receives the user input inputted through a separate user input unit or a remote control terminal (e.g., a smart phone, a boiler device, etc.), receives the user input through the main wiring 30 of the heating block 1 so as to have a specified heating temperature corresponding to the user input, So that the current is supplied through the second terminal. In this case, the intensity of the supplied current can be adjusted corresponding to the target heating temperature.

Regarding the current supply controlled by the controller 5, the power supply capacity necessary for induction heating may be controlled. The power supply capacity required for induction heating is determined by the weight of the object to be heated (heat pipe 100), the heating temperature, and the required heating time.

The required electric power P1 in the case of considering only the heat directly applied to the object to be heated without considering the coupling loss between the coil 25 and the object to be heated is calculated as follows.

P (total required power) = P1 + P2 + P3 + P4

P1: Power absorbed in the object to be heated

P2: Heat Dissipation

P3: Tropical Loss

P4: Heat conduction hand

P1 = conversion factor (4.186) x M x C x DELTA T / heating sec

M: weight (kg), specific heat (cal) of heated object,? T: surface rising temperature (占 폚)

1) Weight of heating part (ST pipe 15A)

W = 3.14 (10.85 ² -8.2 ² ) x 50 x 7.8 ÷ 1000 (g) ÷ 1000 = 0.0618 kg

(1.25 kg / m in the case of steel pipe for piping) = 0.0625 kg (5 cm)

2) average specific heat (in the case of iron: 0.104cal / g ℃)

3) Heating temperature DELTA T (80 DEG C)

* P1 = 4.186 x 0.0625 x 0.104 x 80 = 2.17672 Kw · sec

Based on the above-mentioned equation, the heating ratio according to the existing gas heating and the heating ratio according to the present embodiment are compared as follows.

If you are heating a floor of 20py (py), gas heating will heat up 63ℓ of water inside the 15φ XL pipe.

The heat required to heat 63 l of water at 10 ° C to 80 ° C is as follows.

63 占 폚 (80 占 폚 - 10 占 폚) = 4,410 占

If the thermal efficiency of the boiler is 80%, the heat of 4,410㎉ / 0.8 = 5,512.5. Is required.

Assuming 30 times of heating,

165,375㎉ / 10,500 = 15.75㎥ City gas is consumed.

Average calorific value 42.959 MJ / m3 x 15.75 m3 = 676.604 MJ

Heating price 676.604MJ × 16.1674 won = 10,938 won (Basic charge, VAT excluded)

On the other hand, in the case of induction heating heating according to the present embodiment, the following assumption is made for comparison under the same conditions. 15φ XL pipe 63ℓ of water inside the pipe is 200m piping, so there are 50 places where the heat pipe used for floor construction of 20py is heated.

The power consumed at one place is the same as the following P1, but accurate calculation is difficult due to heat loss, thermal runaway, thermally conductive wire, other circuit loss, coil load coupling loss and plate loss. 5 times.

* P1 = 4.186 x 0.0625 x 0.104 x 80 = 2.17672 Kw · sec

Electricity charge will vary depending on the progression rate per 1kwh.

3600sec = 1h

Based on household rates (base fee and VAT are not included), the following are based on the progressive tax.

2.17672 (power required) × 5 (including loss) × 50 (number of places) × 30 (number of times) / 3600

= 4.535 kwh × 60.7 won = 275.275 won (less than 100 kwh)

= 4.535 kwh x 125.9 yuan = 570.957 yuan (101-200 kwh)

= 4.535 kwh x 187.9 yuan = 852.127 yuan (201-300 kwh)

= 4.535 kwh x 280.6 yuan = 1,272.521 yuan (301 to 400 kwh)

In the case of a commercial office (officetel) (in the case of general-purpose infra-high pressure A selection II), the followings depend on the type of load.

= 4.535 kwh × 66.10 won = 299.764 won (light load)

= 4.535 kwh × 96.50 won = 437.628 won (intermediate load)

= 4.535 kwh x 111.30 yuan = 504.746 yuan (maximum load)

That is, the heating cost according to the present embodiment can be reduced by at least 1/10 times, up to 1/30 times as much as the heating cost by the existing gas heating.

4 and 5 are a perspective view and a plan view showing a heat pipe installation of a heating block according to another embodiment of the present invention.

An installation groove 20 having a predetermined depth is formed on a side surface of the main body 10 of the heating block 1. [ A guide protrusion (60) protrudes from the inner surface of the mounting groove (20).

Guide grooves 130a to 130c having a width corresponding to the guide protrusion 60 are formed on the surface of one side of the heat pipe 100 (e.g., the induction cap 120).

The guide grooves 130a to 130c may have a bent shape having a bent portion 134 once bent at an extension portion 132 extending in the longitudinal direction at the end.

A plurality of guide grooves 130a to 130c may be formed according to the length of the extended portion 132. [ In the present embodiment, the length in the longitudinal direction of the first guide groove 130a to the third guide groove 130c (i.e., the length of the extended portion 132) may become longer (L1 <L2 <L3).

One of the guide grooves 130a to 130c is selected according to the depth to be installed when the heat pipe 100 is inserted into the installation groove 20 and the guide protrusion 60 is inserted into the guide grooves 130a to 130c As shown in Fig.

When the first guide groove 130a is selected, it can be inserted up to L1, and when the third guide groove 130c is selected, it can be inserted up to L3. The number of windings of the coil 25 relative to the induction cap 120 varies according to the depth of the heat pipe 100. Even if the same current flows through the coil 25, The amount of current can vary. If the amount of the secondary current is changed, the generated heat may be changed. That is, the user can freely adjust the heating condition of the heat pipe 100 by a simple operation when the heat pipe 100 is assembled. For example, the depth of the heat pipe 100 positioned at a portion requiring rapid heating in accordance with the environmental conditions of the installation space is deepened, and the depth of installation of other portions is shallow, It can be done in harmony.

Further, by using the guide protrusion 60 and the guide grooves 130a to 130c, the heat pipe 100 can be firmly assembled. When the heat pipe 100 is fully inserted and the guide protrusion 60 is slid to the end of the extended portion 132 in the longitudinal direction, the heat pipe 100 is rotated so that the guide protrusion 60 is inserted into the bent portion 134 of the guide groove . In this case, since the guide protrusion 60 is located in the bent portion 134, it is possible to prevent the heat pipe 100 from being separated from the mounting groove 20, thereby making it possible to assemble firmly.

In the present embodiment, the guide protrusions 60 are provided on the inner surface of the mounting groove 20 and the guide grooves 130a to 130c are formed on the surface of the heat pipe 100. Conversely, A guide groove may be formed on the surface of the heat pipe, and a guide protrusion may protrude from the surface of the heat pipe.

FIG. 6 is a view showing an installation state of a heat fighter according to another embodiment of the present invention.

The assembling of the heat pipe 100 using the guide protrusion 60 and the guide grooves 130a to 130c has been described. In another embodiment of the present invention, a ball plunger is used in assembling the heat pipe 100.

A ball plunger is installed in the mounting groove 20. A ball 70 resiliently supported by a spring is provided on the inner surface of the ball 70 so as to protrude in the direction of the central axis. The ball 70 enters the inner surface by an external force and can spring out in the direction of the central axis by spring elasticity.

A plurality of positioning grooves 140 having a diameter corresponding to the balls 70 may be formed at regular intervals on the surface of the heat pipe 100. The plurality of positioning grooves 140 may be arranged in a straight line.

During the process of inserting the heat pipe 100 into the mounting groove 20, the ball 70 enters into the inner surface of the mounting groove 20 and then comes into contact with any one of the plurality of positioning grooves 140, And can be fitted into the positioning groove (140).

According to the present embodiment, the heat pipe 100 can be easily inserted or separated by applying a large external force to the elastic force of the spring, and the ball 70 is positioned in the position adjusting groove 140 at a desired position, It is possible to achieve a certain level of rigid assembly.

FIG. 7 is a cross-sectional view showing a state before and after installation of a heat pipe according to another embodiment of the present invention.

In the installation groove 20 of the main body 10 according to the present embodiment, a cover structure 80 is provided.

The cover structure 80 includes a cover 82, a spring 88, a support bar 84, and a shorting portion 86.

The cover 82 is elastically supported by a spring 88 so that the cover 82 is located at the outermost side of the installation groove 20 in a state where the heat pipe 100 is not installed. That is, it is possible to prevent penetration of foreign matter and to secure excellent durability.

A support bar 84 having a predetermined length is provided inside the cover 82 and a shorting portion 86 is provided at an end of the support bar 84. At this time, the cover 82 is located in the mounting groove 20, and the shorting portion 86 is located below the bottom surface of the mounting groove 20. That is, the cover 82 and the short-circuit portion 86 are connected to each other by a support bar 84 passing through the bottom surface of the mounting groove 20.

The shorting portion 86 is made of a material (for example, a conductor or a semiconductor) through which a current can flow. The short circuit portion 86 is electrically connected to the two connection terminals 42a and 42b provided on the branch wiring 40 connected to both ends of the coil 25 wound around the installation groove 20.

That is, when the shorting portion 86 meets the two connection terminals 42a and 42b, the shorting portion 86 electrically short-circuits the branching wiring 40, so that no current flows through the coil 25. [ If the shorting portion 86 is moved and separated from the two connection terminals 42a and 42b, the electrical shorting of the branching wiring 40 is released and a current flows through the coil 25. [

(a), the short circuit portion 86 when the cover 82 is located at the outermost side of the installation groove 20 (first position) is connected to the two connection terminals 42a and 42b of the branch wiring 40 I will meet. In this case, current does not flow in the coil 25 even when the heat pipe 100 is not installed, thereby preventing unnecessary current waste and protecting the coil 25 and the peripheral portion thereof.

(second position) when the cover 82 is pushed into the mounting groove 20 by an external force (pressurization of the heat pipe 100) when the heat pipe 100 is installed, The shorting portion 86 connected through the bar 84 is also pushed inwardly and thus the contact of the branch wiring 40 with the two connection terminals 42a and 42b is broken. Thus, the electric short-circuiting of the branch wiring 40 is released, and current can flow through the coil 25. [ When a current flows through the coil 25, the heat pipe 100 inserted into the mounting groove 20 can be heated by induction.

That is, when the cover structure 80 is provided, current flows through the coil 25 only when the heat pipe 100 is installed, and current does not flow when the heat pipe 100 is not installed, And the inside of the installation groove 20 is blocked by the cover 82 from the outside, so that foreign matter can be prevented from being introduced.
