The present invention relates to a cover of a heating hot water pipe and a method of manufacturing the same, and more particularly, a cover for allowing a large amount of heat to be transferred to an ondol layer on an outer surface of a hot water pipe to perform heating, and thus, a floor of an indoor room. By allowing a greater amount of heat to be transmitted to the ondol layer forming a, it relates to a cover of a heating hot water pipe for maximizing the heat dissipation efficiency and heating effect when performing heating in winter and the like and a method of manufacturing the same.

In general, even in winter, in order to maintain an appropriate indoor temperature, a heating device that converts thermal energy or electrical energy by combustion into thermal energy is used.

The heating apparatus is mainly used as a boiler, which consists of a main body for forming hot water through combustion of fuel, and a heating hot water pipe for circulating the heated hot water to a position requiring heating to raise the ambient temperature.

1 and 2 and 3, the heating hot water pipe, the water heated from the boiler (not shown) in a zigzag or coil type between the concrete layer 300 and the ondol layer 200 is a hot water pipe Piped to be circulated through the interior of the (100).

Therefore, the hot water circulated into the hot water pipe 100 heats the hot water pipe 100, and the heat radiated from the hot water pipe 100 is conducted to the ondol layer 200 to perform indoor heating.

Hot water pipe 100 is a metal material having good thermal conductivity, such as copper (copper) or aluminum is used a lot, but the hot water pipe 100 made of a metal material is repeated cooling and heating depending on the change of seasons or the operation of the boiler. As a result, the shrinkage / expansion of the hot water pipe 100 itself is repeated, and corrosion is likely to occur due to chemical action with the aged concrete by-products. This corrosion has a problem that can be to hinder the hot water circulation, or even damage by narrowing or blocking the pipeline of the hot water pipe (100).

Therefore, the production of hot water pipes 100 using synthetic resins, such as chemically crosslinked polyethylene resins (also called Excel pipes), having high corrosion resistance and high shrinkage and expansion rate due to temperature change, such as metal materials, is gradually spreading. The hot water pipe 100 is relatively weak in strength compared to a metal material, and has a defect in that cracks are easily generated or easily broken by external impact or pressure.

Moreover, regardless of whether the hot water pipe 100 is made of metal or synthetic resin, the heating structure of the hot water pipe as in the prior art all has a problem that the heating efficiency is not high.

That is, the distance of the 'a' section of FIG. 3 showing the distance from the upper end of the hot water pipe 100 to the upper end of the ondol layer 200 has a thickness of about 10 mm or more and 30 mm, and the heat of discharge of the hot water pipe 100 is the ondol layer. Not enough to reach the top of the (200). Therefore, the heating efficiency corresponding to the operation rate of the boiler cannot be expected.

Therefore, although the thickness of the ondol layer is conventionally formed to be thin (about 10 mm) for heating efficiency, when the thickness of the ondol layer 200 is formed as described above, cracks may form in the ondol layer 200. There is a problem, which has a problem that can lead to damage of the hot water pipe (100).

The present invention for solving the above problems, by combining the cover of the metal material to increase the heat dissipation area on the outer surface of the hot water pipe installed between the ondol layer and the concrete layer, the heat generation of the hot water pipe through the cover At the same time, when the ondol layer is bonded to the cover in a state in which the bonding force is increased, even when the thickness of the ondol layer is formed thin (about 10 mm) for heating efficiency, the hot water pipe is not cracked in the ondol layer. It is to provide a cover of a heating hot water pipe to prevent damage.

 Another object of the present invention is to provide a method for manufacturing a cover of a heating hot water pipe to cope with a weakness in strength (durability) of a synthetic resin hot water pipe so that the hot water pipe can sufficiently withstand an impact or pressure from the outside.

The object of the present invention and the heat sink is bent to be curved to have the same inner peripheral surface and the outer peripheral surface of the hot water pipe disposed between the concrete layer and the ondol layer; In the configuration consisting of a heat radiation fin protruding to the outside of the heat sink;

The heat dissipation fin is configured by shaping the connecting portion formed between the cutouts in the shape of a fin.

On the other hand, the material of the cover it turns out that the copper material is most preferred.

In addition, it is noted that the heat radiation fin is bent to be arranged in a zigzag.

Hereinafter, the technical configuration of the present invention with reference to the accompanying drawings in detail.

Figure 4 is an exploded perspective view showing a state before the heat sink of the cover is formed so that the heat sink fin is projected to the outside of the hot water pipe, Figure 5 is a perspective view showing a state in which the cover of the present invention is coupled to the hot water pipe, Figure 6 is an enlarged cross-sectional view showing the main portion showing a state installed between the ondol layer and the concrete layer in a state in which the cover of the present invention is coupled to the hot water pipe.

Referring to Figure 4, the cover 400 of the present invention is wrapped around the outer surface of the hot water pipe 100, the heat sink 410 is formed to be bent so as to form an inner peripheral surface and the same as the outer diameter of the hot water pipe 100 is formed And a heat dissipation fin 420 formed to be bent in a plurality of U-shapes to protrude outward of the heat dissipation plate 410.

The heat dissipation fin 420 cuts the cutout portions 440 in a state of maintaining a predetermined interval and length between the connection portions 450, and protrudes the connection portion 450 toward the outside in a ∩ shape.

Meanwhile, as shown in FIGS. 5 and 6, the heat dissipation fin 420 is filled with the concrete material constituting the ondol layer 200 introduced into a space bent in a '∩' shape.

That is, when the hot water pipe 100 is connected to the concrete layer 300 to be heated by the cover 400 in a coupled state, when the ondol layer 200 is constructed of concrete, the ondol layer 200 is formed. As the cement to be formed is poured while being introduced into the space portion in the heat dissipation fin 420, the hot water pipe 100 is firmly coupled to the ondol layer 200.

In addition, the heat dissipation fin 420 is bent to be arranged in a zigzag shape on the outer side of the heat dissipation plate 410, the hot water pipe 100 to which the cover 400 is mounted on the concrete layer 300 and the ondol layer When constructing the 200, the hot water pipe 100 is poured into the ondol layer 200 by being poured while the cement forming the ondol layer 200 flows in a zigzag form on the heat sink 410. Can be installed firmly.

In addition, since the contact area between the heat dissipation fins 420 and the concrete layer is improved, heat dissipation is widely performed by the ondol layer 200, and thus the heat transfer effect is improved.

The cover 400 may be made of a material having high thermal conductivity, such as aluminum (Al) or copper (銅), in terms of improving thermal conductivity and ease of manufacture, and copper (Cu) is preferable. The heat dissipation fin 420 is formed of the same material as the heat sink 410 integrally.

In FIG. 4, the cover 400 may be coupled to the upper surface of the hot water pipe 100 placed on the concrete layer 300 by the inner circumferential surface formed to be bent.

Here, the cover 400 may have a variety of specifications according to the outer diameter of the hot water pipe 100, the action of the cover 400 will be further embodied through the description of FIG.

7 is a process diagram schematically showing a manufacturing method of a cover having a heat dissipation fin according to the present invention, Figure 8 is a plan view showing a state of the sheet being manufactured by the cover manufacturing method of the hot water heating pipe of the present invention, Figure 9 Is a front view showing the state of the sheet being manufactured by the cover manufacturing method of the hot water heating pipe of the present invention,

In the method for manufacturing a cover of the hot water pipe for heating according to the present invention, as shown in FIGS. 7 and 8 and 9, a cutout portion 440 parallel to the conveying direction as the sheet S made of a copper material of a predetermined thickness is transferred. And a punching step (P) for forming a connection portion 450 between the cutouts 440 by sequentially punching the positioning hole 430, and the sheet (S) punched in the punching step (P) by a transfer A heat radiation fin forming step (F) for forming a heat radiation fin 420 by bending the connecting portion 450 between the cutout portion 440 and the cutout portion 440 upward toward the upper portion as it is transferred step by step, and the heat radiation fin forming step. Cutting step (C) for cutting the sheet (S) formed with the heat radiation fins (420) in the required length (F) and the sheet (S) cut to the required size in the cutting step (C) of the hot water pipe 100 Curing step (CU) to obtain a finished product by curling to form the inner peripheral surface equal to the outer diameter is made sequentially It is prepared by.

At this time, the heat radiation fin 420 is bent so that the cross section is arranged in a zigzag at both ends of the connection portion 450 in the '∩' shape.

Therefore, the positioning hole 430 and the cutout 440 are formed while the sheet S introduced into the puncher passes through the punching step P, and the positioning hole 430 and the cutout 440 are formed. The sheet S is transferred by the transfer step by step to form a heat radiation fin 420 in a zigzag form.

At this time, the reason for forming the heating fin 420 in the '∩' shape is that the concrete material is filled therebetween as well as the effect of excellent bonding force, the heat dissipation fin 420 has a self-elasticity, so it is coupled with the hot water pipe 100 Tension can be acted on at the bending position when heating at.

That is, when the inside of the hot water pipe 100 is bent in a circular shape in the process of piping is compressed and the outside is tensioned, the cover 400 coupled to the outside of the hot water pipe 100 is required to stretch and deform together. , The heat dissipation fin 420 is to be stretched or contracted in the state of being molded into a w-shape to enable the elastic deformation action.

Therefore, when the hot water pipe 100 is piped in a state in which the cover 400 is coupled, the pipe work can be quickly and easily made while bending the shape freely in a bent position.

On the other hand, the sheet (S) formed with the heat radiation fin 420 while passing through the heat radiation fin forming step (F) as described above is cut to the length required during the operation while going through the cutting step (C), the cutting step ( The sheet (S) is cut to the length required for the work in C) is finally produced by curling (Curling) to be formed in a circular shape in which one side is opened in consideration of the outer diameter of the hot water pipe 100 You lose.

6 is a partially enlarged cross-sectional view showing an installation state of a cover having a heat radiation fin according to the present invention.

Referring to Figure 6, the hot water pipe 100 in the form of a cylindrical tube is usually installed in a predetermined arrangement form (see Fig. 1) on the concrete layer 300 constituting the floor of the building, one side above the hot water pipe 100 This open cylindrical cover 400 is in the form of being coupled.

In this case, since the cover 400 is formed by bending a sheet shape of a thin copper material, the elasticity is excellent, so that the opened opening is opened by applying a small force to the opened opening, and when the cover 400 is inserted into the hot water pipe 100, the coupling is easily performed and the mutual coupling is easily performed. will be.

Then, the ondol layer 200 is formed on the cover 400, so that the heat of the hot water pipe 100 is radiated to the ondol layer 200 via the cover 400.

At this time, the cover 400 is to be used by cutting to a predetermined length, it turns out that it can be installed in succession to cover the entire section of the pipe of the hot water pipe 100 installed on the concrete layer (300).

Alternatively, only a part of the hot water pipe 100 may be selectively taken or partially covered by a drop formula, which may be selected and changed by a designer according to the length of the cover 400, thermal efficiency, and material cost.

The inner circumferential surface of the cover 400 is preferably one side of a cylindrical shape, if the shape is a circular arc smaller than a semicircle, the contact area between the cover 400 and the hot water pipe 100 is reduced and the bonding force is small, the heat transfer efficiency is so small It is not desirable to lose.

The heating action of the heat dissipation structure of the hot water pipe configured as described above is as follows.

Referring to FIG. 6, when hot water heated from a boiler (not shown) circulates inside the hot water pipe 100, the heat of the hot water heats the hot water pipe 100 and the heated hot water pipe 100 is Since it is in contact with the heat sink 410 in contact with the outer circumferential surface it conducts heat evenly to the position of the heat sink 410 and the heat radiation fin 420.

As a result, heat is transmitted and released to the ondol layer 200 which is in contact with the circumference of the heat sink 410 and the surfaces of the plurality of heat sink fins 420.

In this case, thermal expansion of the heat dissipation fin 420 itself may be compensated for in a space (interval) between the heat dissipation fins 420.

As the heat dissipation fins 420 are formed, the total sum of the outer surface of the heat dissipation plate 410 and the surface areas of the heat dissipation fins 420 is larger than the surface area of the hot water pipe 100 of the cylindrical tube, thereby increasing the contact (heat transfer) area. You can increase it.

In addition, the heat transfer to the ondol layer 200 proceeds quickly, and as shown in FIG. 6B, the uppermost distance between the heat dissipation fins 420 and the ondol layer 200 is relatively larger than the distance from the general hot water pipe 100. Because it can be shortened by about 1/2, the heat transfer to the ondol layer 200 may be well.

In addition, even when a thick (not cracking) ondol layer 200 is formed as in the related art, the heat transfer distance can be shortened by the heat dissipation fins 420, resulting in high energy efficiency, leading to energy saving.

In addition, the cover 400 has a cylindrical structure covering the upper portion of the hot water pipe 100, and concentrates and transfers heat to the upper portion of the ondol layer 200 that needs to substantially transmit heat for heating. This results in higher heating efficiency. This cover made of copper recovers the hot water heat in the hot water pipe 100 and transfers it upward, considering that the heat is about to rise.

In other words, when the cover 400 is manufactured in a cylindrical shape covering the entire outer circumferential surface of the hot water pipe 100, the cover 400 emits heat to the bottom of the ondol layer, which does not need to conduct heat substantially for heating. Loss occurs. That is, the present invention can save energy.

According to the cover of the heating pipe having a heat dissipation fin according to the present invention as described above, not only the contact area between the cover heated from the hot water pipe and the ondol layer is widened, but also the heat dissipable portion (heat dissipation fin) and the top of the ondol layer. Since the distance is also shortened, the heat transfer rate to the ondol layer is fast and the range of heat transfer is widened, thereby minimizing heat loss and improving heating efficiency.

Furthermore, since the cover of the present invention is structured to be placed only on the upper side of the hot water pipe, assembly with the hot water pipe is easy, and heat dissipation heat is concentrated and transferred to the upper side of the ondol by the cover, thereby improving the heating efficiency. It has the advantage of saving energy.

In addition, the cylindrical cover is open on one side is not only easy to manufacture by various means, it is also easy to install because it only needs to be covered with a hot water pipe.

In addition, since the heating pipe cover of the present invention is made of a metal material having a relatively higher strength than the synthetic resin hot water pipe, and covers the upper portion of the hot water pipe, it is applied from the impact during curing for the construction of the ondol layer or from the top of the ondol layer. It can eliminate risk factors such as hot water pipe cracking or cracking by losing load.

That is, since the hot water pipe made of a resin material can be protected from impact and pressure from the outside, there is also an advantage that the durability of the heating piping structure as a whole is improved.

In addition, since the projection-shaped heat-dissipating fin is formed, it is possible to form a non-thin ondol layer while sufficient heat transfer, there is also an effect that can prevent the crack of the ondol layer.
