본 발명은 온돌난방용 전열관으로서 안전성과 열효율의 극대화를 위하여 알루이늄관 샤시내부에 열전도와 잠열보지 효과를 큰 전열재를 혼합 내장하고 2중의 절연체로 커버 밀봉하여 온도조절의 보상기능을 갖도록한 온도난방용 알루미늄제 전열관에 관한 것아다.The present invention is a heating heating tube for heating and heating to heat the aluminum aluminum chassis in order to maximize the safety and thermal efficiency, the heat conduction and latent heat preservation effect is mixed with a built-in heat transfer material and double insulation to cover the temperature of the aluminum to have a temperature control compensation function It's about my heat pipe.

종래에 있어서는 난방용으로 합성수지제파이프, 동파이프, 철제파이프, 스테인레스파이프등이 온수관을 보일러에 연결하여 난방효과를 높이거나, 아연 또는 동파이프내에 운모등의 전열재를 일부 삽입하여 전열파이프로서의 기능을 대체해왔으나 전자의 경우는 보일러를 사용하므로서 설비비가 많이 들고 동절기에 동파의 우려가 크며, 철재보일러의 가열관에서 발생하는 녹을 막을 수 없어 온수의 흐름을 방해하게 되고 나아가 수명단축 및 파손이 초래되고 이로 말미암아 수리비 및 관리비의 낭비를 초래하기 일쑤였으며, 또한 난방배연관의 열전도율이 낮음으로 인해 열효율이 떨어지고 연료비도 증가하는등 문제점이 많았다.Conventionally, for heating purposes, synthetic pipes, copper pipes, steel pipes, stainless pipes, etc., connect the hot water pipes to the boiler to increase the heating effect, or function as heat transfer pipes by inserting some heat transfer material such as mica into zinc or copper pipes. However, in the former case, boilers are used, which leads to high equipment costs and high risk of freezing in the winter. It also prevents rust from heating tubes of steel boilers, which hinders the flow of hot water and further shortens the life and damages. This causes waste of repair and maintenance costs, and also has a lot of problems such as low thermal efficiency and increased fuel cost due to the low thermal conductivity of the heating pipe.

또한 후자의 경우에서도 아연 또는 동파이프내에는 절연체로 코일을 감싸고 다시 그위에 운모등을 내장한것이 있으나 이는 절연제가 깨어지는 경우 누전이 발생하는등 절연효과를 기대할 수 없을 뿐만 아니라 운모등의 단순한 전열재로서는 열전도가 빠르면서도 지속적인 복사난방이 어려우며 환형의 저전열성 파이프이기때문에 열의 복사 범위가 좁아 열효율이 떨어지며, 온도조절에 있어서도 온도조절기의 기능이 마비될 경우, 즉 과부하가 걸리거나 노후로 인하여 제기능을 발휘하지 못하는 경우 과열되어 치명적인 재난을 초래할 수있는 문제점이 있는 것이었다.Also, in the latter case, there is a coil inside the zinc or copper pipe with an insulator, and there is a built-in mica light on top of it. However, if the insulation is broken, it is not possible to expect an insulation effect such as a short circuit. As heat conduction is difficult, continuous radiant heating is difficult, and because it is an annular low-heating pipe, the heat radiating range is narrow, so the thermal efficiency is low. If not, there was a problem that could overheat and cause catastrophic disaster.

본 발명은 이러한 제반 문제점을 해결하기 위한 것으로 관상부에 넓은 열방사면을 형성하여 하부를 상광하협으로 형성한 알루미늄제 관샤시를 사용하여 내부에 열보전성이 큰 전열재를 내장하되 1차 절열재외에 2차절연층을 피복하며, 주바이메탈 보다 온도 특성이 높은 보상바이메탈을 연설하여 상기한 바와 같은 온수보일러와 파이프 전열관의 결점을 일소시키려 함에 그 목적이 있는 것으로, 이를 첨부된 도면에 의거하여 상세히 설명하면 다음과 같다.The present invention is to solve the above problems and to form a large thermal radiation surface in the tubular part by using a tube made of aluminum formed in the upper and lower strait to the interior of the heat-insulating material having a large thermal integrity in addition to the primary thermal insulation material The purpose of the present invention is to cover the secondary insulating layer and to compensate the defects of the hot water boiler and the pipe heat pipe as described above by addressing the compensation bimetal having higher temperature characteristics than the main bimetal, which will be described in detail with reference to the accompanying drawings. Is as follows.

먼저 제2도에서와 같이 내측면으로 실리콘피복층(9)이 코팅처리된 관샤시(14)대의 중앙으로 석면부재(8)를 관통시켜 심봉으로 하되, 그 외주면상에는 발열코일(7)을 권설하여 그 양단을 관샤시(l4)의 전,후단부에 방수용 접착제로 부착 고정된 실리콘캡(4)을 관통한 접속핀(3)에 연결하고 발열코일(7)의 외주면으로는 다시 실리콘으로된 절연관(6)을 씌워 고정지지링(5)에 의해 관샤시(14)내에는 고정지지되게 하였으며, 관샤시(14)와 절연관(6)의 공간에는 소의 유리구슬(11) 30%와 규석(12) 50% 및 규사(13) 20%로 혼합된 절연재를 충진시켜 전열관(1)을 형성하고 이같은 전열관(1)은 상광하협으로 형성되어 상부양측에는 돌출부(21)(21')가 형성되고, 전열관(1)의 상단 양측으로는 반구형 요부(10)(10')를 형성되게 한것으로, 위와같이 구성된 본 발명 전열관(1)을 시공할 경우는 먼저 접속핀(3)을 접속플러그(도시안됨)로서 제6도에서와 같이 상호간에 병렬연결하여 제5도에서와 같이 몰탈(15)내에는 매설하게 되는데 매설된 상태에서는 전열관(1) 상부의 반구형요부(10)(10')에 의해 관샤시(14)의 강도가 증대되므로 비틀림이 방지되는 것임은 물론 몰탈(15)과의 결착 또는 견고토록한 것이다.First, asbestos 2 penetrates the asbestos member 8 to the center of the tube chassis 14 coated with the silicon coating layer 9 to the inner side to form a core rod, and on the outer circumferential surface, a heating coil 7 is recommended. The both ends are connected to the connecting pins 3 through the silicon cap 4 fixed to the front and rear ends of the tube chassis l4 with a waterproof adhesive, and the silicon is cut back into the outer circumferential surface of the heating coil 7. The tube (6) was covered to be fixed in the tube chassis (14) by the fixed support ring (5), and 30% of the glass beads (11) and silica in the space of the tube chassis (14) and the insulated tube (6). (12) Filling the insulating material mixed with 50% and 20% of the silica sand (13) to form a heat pipe (1), and such heat pipe (1) is formed by the upper and lower strait so that the protrusions (21, 21 ') formed on both sides of the upper When the heat transfer pipe 1 of the present invention configured as described above is formed to have hemispherical recesses 10 and 10 'formed at both upper ends of the heat transfer tube 1. First, the connecting pins 3 are connected to each other in parallel as shown in FIG. 6 as connection plugs (not shown) and embedded in the mortar 15 as shown in FIG. 5. In the embedded state, the upper part of the heat pipe 1 The hemispherical recesses 10 and 10 'of the tube chassis 14 are increased in strength, as well as being prevented from twisting, as well as binding or firmness with the mortar 15.

이같이 몰탈(15)내에는 매설된 전열관(1)은 상부양측 돌출부(21)(21')에 의해 열의 흐름을 유도하여 열의 좌우방향 방사도를 높혔으며 연의 보존력 또한 지속시킬 수 있는 것이며, 관샤시(14) 내측면으로 실리콘 피복층(9)을 형성시켰기 때문에 실리콘으로된 절연관(6)이 파손되는 경우에도 모체인 관샤시(14)로 전기전도를 방지할 수 있는 것이고, 관샤시(14)와 절연관(6)간에 혼합 충진된 절연재의 기본적인 조성비율은 전술한바의 구성설명 즉 제4도(a)에서와 같은 비율이 열보존 효과(잠열보지효과)를 높히는 가장 이상적인 비율인 것이되, 제4도(b)에서와 같이 유리구슬(11) 37.5%와 규석(12) 62.5%만을 혼합할 수도 있고, (c)에서와 같이 유리구슬(11) 60%와 규사(13) 40%만을 혼합할 수도 있으며, (d)에서와 같이 규석(12) 71.4%와 규사(13) 28.6%만을 혼합할 수도 있고 (e)에서와 같이 규석(12)만으로 충진하여도 상기한바의 열보존효과보다 떨어지나 또한 종래의 온수관을 보일러에 연결하는 것이나, 파이프내에는 운모등의 전열재를 삽입한 전열파이프보다 열보존 효과가 높은 것으로 이를 제7도 온도 특성 비교도와 관련하여 좀더 상세히 설명하면 500ml의 비이커에 동일부피로 각각의 전열재를 담고 LPG가스 중간불꽃으로 10분간 가열하였을 경우 온도대 시간의 잠열효과의 전도율은 유리구슬-규석-규사의 경우가 가장 양호하고 순도 99% 이상의 규석분100%의 경우가 그보다 약간 떨어지나 이 또한 극히 양호한 것으로 나타났으며 나머지도 종래 전열파이프 보단 양호한 것이다.In this way, the heat transfer pipe 1 embedded in the mortar 15 induces a flow of heat by the upper both side protrusions 21 and 21 'to increase the lateral radiation of the heat and to maintain the retention of the kite. (14) Since the silicon coating layer 9 is formed on the inner side, even when the insulating tube 6 made of silicon is broken, the electrical conduction can be prevented by the parent tube chassis 14, and the tube chassis 14 The basic composition ratio of the insulating material mixed and filled between the insulating tube and the insulating tube 6 is the ratio as described in the above description, that is, the ratio as shown in FIG. 4 (a) is the ideal ratio for increasing the heat preservation effect (latent heat preservation effect). As shown in FIG. 4 (b), only 37.5% of glass beads (11) and 62.5% of silica (12) may be mixed, and 60% of glass beads (11) and 40% of silica (13) may be mixed as in (c). Only the mixture may be mixed, and as in (d), only 71.4% of silica (12) and silica (13) may be mixed. As such, filling with only silica (12) is less than the heat preservation effect described above, but it is also connected to a conventional hot water pipe to the boiler, and the heat preservation effect is higher than the heat transfer pipes in which heat transfer materials such as mica are inserted into the pipe. More specifically with respect to the temperature characteristics comparison diagram, the conductivity of the latent heat effect of the temperature vs. time when the heat transfer material is contained in the same volume in 500 ml beaker and heated for 10 minutes with the medium flame of LPG gas is the glass beads-gyu-seok- The case of silica sand is the best and the case of 100% of silica powder with purity of 99% or more is slightly lower than that, but it is also shown to be extremely good and the rest is better than the conventional heat transfer pipe.

여기서 운모와의 비교는 제외하였는데 이는 운모가 고가이고 전도율이 낮아 예열시간이 길며 잠열시간은 비교적 짧고 분말화할 경우 물의 경우보다 온도 특성이 낮아 실용성이 없으므로 비교대상에서 제외한 것이다.Here, the comparison with mica is excluded. This is because mica is expensive and its conductivity is long, so the preheating time is long, and the latent heat time is relatively short.

또한, 이와 같은 전열관(1)은 회로구성에 있어서 통상 주바이베탈(18)만을 사용하여던 것을 과부하가 걸리거나 장시간 사용에 따른 온도조절기능이 떨어지는 것을 방지하기 위하여 소형의 보상바이메탈(2)을 각각전열관(1)에 설치하여, 제6도에서 보는 바와 같이 주바이메탈(18)이 55℃에서 탈점되면 전원램프(19)가 OFF되는 통상의 경우와 달리 각 전열관(1)에 이상이 발생할 경우와 주바이메탈(18) 온도특성이 떨어질 경우 상승하는 온도를 각각 보상바이메탈(20)에서 60℃로 잡아준다.In addition, such a heat transfer tube 1 has a small compensation bimetal 2 in order to prevent overloading of the use of only the main main valve 18 in the circuit configuration or deterioration of the temperature control function due to long-term use. When the heat transfer pipes 1 are installed on the heat transfer pipes 1, and as shown in FIG. 6, when the main bimetal 18 desorbs at 55 ° C, when the power lamps 19 are turned off, the heat transfer pipes 1 are abnormal. When the main bimetal (18) temperature characteristic falls, the rising temperature is set to 60 ℃ in the compensation bimetal (20), respectively.

이상과 같은 본 발명은 누전의 방지와 온도조절 보상기능을 갖춤과 동시에 특수한 전열재와 알루미늄관샤시를 사용하므로서 열보전성과 열방아사성이 뛰어날 뿐만 아니라 경험이 없는 초보자라도 쉽게 경제적으로 시공설치할 수 있으며 부속시설이 없고 안정성이 커서 경제적 효과 또한 큰 것이다The present invention as described above has a heat transfer prevention and temperature control compensation function and at the same time by using a special heat transfer material and aluminum tube chassis, excellent heat preservation and heat dissipation, and even beginners can be economically installed easily. There is no attached facility and the stability is large, so the economic effect is also great.
