본 발명에 의하면 보일러에서 공급되는 고온의 가열유체로 내부라인 외면의 열매체가 기화되어 외부라인의 내부를 이동하기 때문에 배관의 설치 길이나 각도(기울기, 구배)의 제약 없이 사용이 가능하며, 보일러에서 순환되는 가열유체의 관수량을 현저히 감소시켜 보일러 설치 용량을 줄여 사용할 수 있는 효과가 있다.According to the present invention, since the heating medium on the outer surface of the inner line is vaporized with the high-temperature heating fluid supplied from the boiler and moves inside the outer line, it can be used without restrictions on the installation length or angle (slope, gradient) of the pipe, and in the boiler It has the effect of reducing the boiler installation capacity by significantly reducing the amount of irrigation of the circulating heating fluid.
또한, 내부라인과 외부라인 사이를 진공 또는 부진공으로 유지시켜 내부라인으로 공급되는 가열유체를 일반 배관 난방에 비해 상대적으로 적은 1/3 ∼1/2 양만으로도 열매체를 빠르게 기화 및 증발시킬 수 있기 때문에 적은 에너지만으로 동일한 난방효과를 달성할 수 있는 것이다. In addition, since the heating fluid supplied to the internal line can be quickly vaporized and evaporated with only 1/3 to 1/2 of the heating fluid supplied to the internal line by maintaining a vacuum or sub-void between the internal line and the external line. It is possible to achieve the same heating effect with less energy.
또한, 가열유체의 열을 이용하여 열매체를 상변화 시켜 잠열 이동방식으로 열을 전달하게 되면, 일반적인 가열유체의 열전달 방식이 열이 높은 곳으로부터 낮은 곳으로 서서히 이동하는 전도열 방식, 즉 현열이동방식인 것에 비해 월등히 높은 3∼5배의 열전달이 이루어짐으로써, 현열이동방식 난방 대비 상대적으로 1/3 정도의 적은 에너지만으로 동일한 난방효과를 달성할 수 있는 것이다. In addition, when the heating medium is phase-changed using the heat of the heating fluid and heat is transferred by the latent heat transfer method, the general heat transfer method of the heating fluid is a conductive heat method in which the heat slowly moves from a high place to a low place, that is, a sensible heat transfer method. Since heat transfer is 3 to 5 times higher than that of heat transfer, the same heating effect can be achieved with relatively less energy of about 1/3 compared to sensible heat transfer heating.
또한, 외부라인의 일단과 타단에 열매체 순환관을 형성하기 때문에 내부라인의 외면에 함침된 열매체의 차등 가열에 의한 기화율에 차이가 발생되더라도 가장 먼저 기화되는 외부라인의 열매체가 가장 나중에 기화되는 외부라인으로 이동하여 외부라인 전체를 신속하고 고르게 가열시켜 난방효율을 증가시킬 수 있는 효과가 있다.In addition, since the heating medium circulation tube is formed at one end and the other end of the outer line, even if there is a difference in the vaporization rate due to differential heating of the heating medium impregnated on the outer surface of the inner line, the heat medium of the outer line that vaporizes first is vaporized last. It has the effect of increasing the heating efficiency by moving to the line and heating the entire external line quickly and evenly.

The outer line 10 has a predetermined length in an open shape. In this case, the outer line 10 is preferably a material having high thermal conductivity so that the heat of the heating fluid is easily transferred to the surface. This external line 10 may be buried in the floor for residential heating, commercial use as a radiator, etc., buried in the soil of a house for industrial purposes, or used as a radiator.
한편, 외부라인(10)의 내부면은 직선, 또는 나선형 그루브(11)를 형성되는 것이 바람직하다. 이러한 직선, 또는 나선형 그루브에 의해서 내부라인(20)의 가열된 열매체(40)가 외부라인(10)의 내부면에서 응결되어 발생하는 응축수가 모세관 현상으로 흡수되고, 직선 또는 나선형 그루브를 따라 중력에 의해 외부라인(10)의 하단으로 용이하게 회귀되게 된다.On the other hand, it is preferable that the inner surface of the outer line 10 is a straight line or a spiral groove 11 is formed. The condensed water generated when the heated heating medium 40 of the inner line 20 is condensed on the inner surface of the outer line 10 by such a straight or spiral groove is absorbed by a capillary phenomenon, and is subjected to gravity along the straight or spiral groove. By this, it is easily returned to the lower end of the outer line 10 .
내부라인(20)은 외부라인(10)의 내부를 따라 위치하면서 일단과 타단이 외부라인(10)의 외측으로 연장되어 있으며, 일단으로 보일러에서 가열된 가열유체가 유입되어 내부를 관류하면서 타단으로 배출된다. 이때, 내부라인(20)은 가열유체의 열이 용이하게 표면으로 전달되도록 열전도율이 높은 물질이 사용되는 것이 바람직하다. 이러한 내부라인(20)은 일단이 보일러의 유출구에 연결되고 보일러의 유입구에 연결되어 가열유체를 순환시키면서 내부라인(20)의 외면을 가열하게 된다. 이때, 내부라인(20)을 순환하는 가열유체는 일반적인 보일러에서 사용되는 온수, 또는 오일 인 것이 바람직하다.The inner line 20 is positioned along the inside of the outer line 10, and one end and the other end extend to the outside of the outer line 10, and the heating fluid heated in the boiler flows into one end and flows through the inside to the other end. is emitted In this case, the inner line 20 is preferably a material having high thermal conductivity so that the heat of the heating fluid is easily transferred to the surface. One end of the inner line 20 is connected to the outlet of the boiler and connected to the inlet of the boiler to heat the outer surface of the inner line 20 while circulating the heating fluid.

In addition, the inner line 20 further includes a gap maintaining portion 21 that protrudes outward in a radial shape at regular intervals from the outer surface. It is possible to prevent heating by directly contacting the outer line 10 by maintaining a constant interval of the inner line 20 positioned inside the outer line 10 by the spacing maintaining unit 21 .
함침부(30)는 내부라인(20)의 외면에 밀착되어 있으며 열매체(40)가 함침된다. 이때, 함침부(30)는 다공질 및 난연성의 성질을 갖는 난연성 섬유인 것이 바람직하다. 이러한 함침부(30)는 내부라인(20)이 외부라인(10)에 직접 접촉을 방지하는 차단재 역할을 하고, 다공질의 공극(Pore)에 열매체가 안정적으로 함침되며 이탈을 최소화한다. 또한, 다공질의 함침부 공극(Pore)에 가열유체가 분자구조로 함침됨으로써 용이한 가열, 기화될 수 있게 되다. The impregnated part 30 is in close contact with the outer surface of the inner line 20 and the heating medium 40 is impregnated. In this case, the impregnated portion 30 is preferably a flame-retardant fiber having porous and flame-retardant properties. The impregnated portion 30 serves as a barrier material preventing the inner line 20 from directly contacting the outer line 10, and stably impregnates the porous pore with a heating medium and minimizes separation. In addition, the heating fluid is impregnated with a molecular structure in the pores of the porous impregnated part, so that it can be easily heated and vaporized.
한편, 함침부(30)는 열매체가 용이하게 흡입하고 배출될 수 있는 유로를 구성하고, 아울러 진공 배기과정에서 잔존 공기가 용이하게 배출될 수 있도록 배기로가 구성되도록 소정거리 이격되면서 일정폭으로 내부라인(20)의 길이방향으로 위치하는 다수개의 분리된 서브함침부(31,32,32)로 이루어지는 것이 바람직하다. On the other hand, the impregnated part 30 constitutes a flow path through which the heating medium can be easily sucked and discharged, and is spaced apart by a predetermined distance to form an exhaust path so that the residual air can be easily discharged in the vacuum exhaust process. It is preferable to consist of a plurality of separate sub-impregnated portions 31 , 32 , 32 positioned in the longitudinal direction of the line 20 .

In addition, a refrigerant with low viscosity and high thermal conductivity in liquid and gaseous phases, which is not flammable and harmless to the human body, may be used. In addition, the amount of the heating medium 40 impregnated in the impregnated portion 30 of the inner line 20 is used, and in particular, it is preferable to use 20 to 80% by weight based on the total impregnable amount. When the heating medium 40 is heated, it moves between the inner line 20 and the outer line 10 in a gaseous phase to rapidly increase the overall temperature and maintain it evenly.
