Description

발열장치를 구비한 방열기{A radiator equipped with a heating device}[0001] The present invention relates to a radiator equipped with a heating device,

본 발명은 발열장치를 구비한 방열기에 관한 것으로, 더욱 상세하게는 열효율을 증대시켜 전력소모를 절감할 수 있는 발열장치를 구비한 방열기에 관한 것이다. BACKGROUND OF THE INVENTION 1. Field of the Invention [0001] The present invention relates to a radiator having a heating device, and more particularly, to a radiator having a heating device capable of increasing thermal efficiency to reduce power consumption.

일반적으로 발열장치는 방열기, 온풍기, 식기건조기, 빨래건조기 등에 사용되고 있다.In general, a heating device is used in a radiator, a hot air fan, a dish dryer, a laundry dryer, and the like.

상기 발열장치의 일 실시예로써 전술한 방열기를 예로 들어 살펴보면, 상기 방열기(radiator)는 실내의 난방을 목적으로 설치된 것으로, 다수개의 방열판과, 상기 방열판에 통하도록 상,하부에 결합부로 구성된다.For example, the radiator is provided for heating the room, and includes a plurality of heat dissipating plates, and upper and lower joining parts for communicating with the heat dissipating plates.

상기 방열판 및 통체 내에 오일이나 물과 같은 열매체유를 충전시킨 후 상기 결합부의 내측에 발열장치를 설치하여 구성된다.And a heating device is installed inside the coupling portion after filling the heat dissipation plate and the cylinder with a heating medium such as oil or water.

전술한 방열기는, 발열장치가 대개 방열판의 하부에 구비된 통체 내에 설치되며, 상기 발열장치의 발열에 의해 방열판 내의 유체를 가열함으로써 발열이 되도록 하였다.In the above-described radiator, a heat generating device is usually provided in a tubular body provided below the heat radiating plate, and heat is generated by heating the fluid in the heat radiating plate by the heat generated by the heat generating device.

상기 발열장치는 대략 "U"자형으로 된 발열코일 내에 발열선이 삽입된 후 그 끝단에 전원선의 (+)극과 (-)극이 연결된 것으로, 상기 전원선을 통해 전원이 인가되면 상기 발열선이 발열됨으로써 열전달이 이루어질 수 있게 된다.In the heating device, a heating wire is inserted into a heating coil having a substantially U shape, and a (+) pole and a (-) pole of a power line are connected to the end of the heating wire. When power is applied through the power line, Heat transfer can be achieved.

그러나 종래 기술에 따른 방열기는 전력 소비가 많은 문제점이 있었다. 즉, 15핀의 종래 발열장치는 통상 3kw를 소모하게 되는데, 1단모드에서 약 1000w가 소모되고, 2단모드에서 약 2000w 가 소모되므로 전력 소모량이 많은 단점이 있었다.However, the radiator according to the related art has a problem of high power consumption. That is, a conventional 15-pin heat generating device usually consumes 3 kW, which consumes about 1000 W in the first stage mode and consumes about 2000 W in the second stage mode.

또한 종래 기술에서는 발열선을 지지하는 절연 고정구가 마그네슘을 주원료로하는 도자기로 제작되는데 파손되는 단점이 있었다. Also, in the prior art, there is a disadvantage that the insulating fixture for supporting the heating wire is made of ceramics containing magnesium as its main raw material and broken.

또한 종래 기술에서는 발열선이 수용되는 발열관체가 길이가 길어질수록 쳐짐이 발생되어 발열선과 방열기를 연결하는 부위에 유격이 생겨서 내부의 열매체유가 누설되는 문제점이 있었다. Also, according to the related art, there is a problem that as the length of the heating tube accommodating the heating wire becomes longer, a stiction is generated and a clearance is formed at a portion connecting the heating wire and the heat sink, thereby leaking the inner heating oil.

한국 등록특허 10-0733280호Korean Patent No. 10-0733280

본 발명의 목적은, 다수의 방열판이 연결되어 구성되고, 하부에는 발열장치가 수용되는 결합부가 형성되며, 열매체유가 충진되어 이루어지는 방열기에 적용되는 것으로, 상기 발열장치는, 전도율이 높은 발열관체; 상기 발열관체의 내부에 다수로 결합되며 절연 고정구; 상기 절연 고정구에 결합되며 발열관체의 내부에 수납되며 전원선과 연결되는 발열코일;을 포함하되, 상기 절연 고정구의 외주면과 상기 발열관체의 내주면에 틈새가 형성되고, 상기 틈새에 충전되는 단열 충진재를 포함하며, 상기 발열관체의 외주면에 외부링이 형성되고, 상기 외부링은 방열판의 결합부에 접촉 지지되어 이루어지는 발열장치를 구비한 방열기에 의해 달성될 수 있다. An object of the present invention is to provide a radiator having a plurality of radiating plates connected to each other and a coupling portion for receiving a heating device at a lower portion thereof and filled with thermal oil, A plurality of insulated fixing members coupled to the inside of the heating tube; And a heat-generating coil coupled to the insulating fixture and housed in the heat-generating tube and connected to a power line, wherein a gap is formed in an outer circumferential surface of the insulating fixture and an inner circumferential surface of the heat-generating tube, and the heat- And an outer ring is formed on an outer circumferential surface of the heating tube, and the outer ring is in contact with the coupling portion of the heat sink.

상기 발열관체의 외주면에 결합되며 외부링의 양측에 배치되며 방열판의 결합부에 지지되는 열전달부재를 포함하는 것을 특징으로 한다. And a heat transfer member coupled to the outer circumferential surface of the heating tube and disposed on both sides of the outer ring and supported by the coupling portion of the heat sink.

상기 열전달부재는 구리와 아연을 혼합한 다공질금속망인 것을 특징으로 한다. And the heat transfer member is a porous metal mesh in which copper and zinc are mixed.

상기 절연 고정구는 산화마그네슘, 산화알루미늄, 이산화규소, 산화철의 혼합물로 이루어지는 것이며, 원통형으로 소성 가공되고, 측면에는 발열코일이 삽입되는 절개홈이 길이방향으로 형성되어 이루어지고, 상기 다수의 절연 고정구가 직렬배치되어 상기 발열관체의 길이에 대응하는 길이를 갖도록 형성되는 것을 특징으로 한다. Wherein the insulating fixture is made of a mixture of magnesium oxide, aluminum oxide, silicon dioxide, and iron oxide, and is formed into a cylindrical shape by plastic working, and a side surface of the insulating fixture is formed with a cutout groove for inserting a heat generating coil in the longitudinal direction, And are arranged in series so as to have a length corresponding to the length of the heating tube.

본 발명에 따르면, 절연 고정구의 파손이 방지될 수 있어 내구성이 향상될 수 있으며, 열 발산 면적을 높일 수 있고, 균일한 가열면적이 증가될 수 있으며, 낮은 전력소모로도 높을 발열 효과를 얻을 수 있는 효과가 있다. According to the present invention, breakage of the insulating fixture can be prevented, durability can be improved, heat dissipation area can be increased, a uniform heating area can be increased, and a high heating effect can be obtained even at a low power consumption It is effective.

장시간 끄지 않고 오랜 시간 사용할수록 공간 내 열을 지속하기 유리하여 열효율이 증대될 수 있다. The longer the use for a long time without turning off the power for a long time, the more the heat in the space can be sustained and the thermal efficiency can be increased.

기존 가열작동 25분 가열, 15분 차단 반복에서의 단점을 보완할 수 있다. It is possible to compensate for the drawbacks of the existing heating operation for 25 minutes heating and 15 minutes for repeated heating.

기존 절연 고정구는 마그네슘 성분이 많아 그 탄성이 떨어져 열을 장시간 지속유지함에 미비하였으나 본 발명은 성분 조성물을 개선하여 안정적인 효과가 있다. The conventional insulating fixture has a low magnesium elasticity due to its large amount of magnesium components, which is insufficient for keeping the heat for a long time. However, the present invention improves the composition composition and has a stable effect.

또한 외부링이 발열관체의 쳐짐을 방지함으로써 발열관체와 방열기의 체결부위에 유격이 발생되어 내부 열매체유가 누설될 우려를 예방할 수 있는 효과가 있다. In addition, since the outer ring prevents the heating tube from being squeezed, there is an effect that it is possible to prevent the inner heating medium oil from leaking due to the occurrence of clearance at the coupling portion between the heating tube and the radiator.

상기 방열판(100)은 내부에 공간이 형성되고 상부 및 하부 양면에는 개구공을 갖는 원통형상의 포트가 형성된 것으로, 다수의 방열판(100)이 병렬 배치되고 각 포트가 서로 통하도록 연결됨으로써 결합부(120)가 형성되고, 결합부(120)는 원통형상을 구성하게 된다. A plurality of heat sinks 100 are arranged in parallel, and the ports are connected to each other to communicate with each other. As a result, the heat sinks 100 (120) And the engaging portion 120 constitutes a cylindrical shape.

상기 발열장치(H)는, 전도율이 높은 발열관체(2); 상기 발열관체(2)의 내부에 다수로 결합되며 절연 고정구(4); 상기 절연 고정구(4)에 결합되며 발열관체(2)의 내부에 수납되며 전원선과 연결되는 발열코일(6);을 포함한다. The heating device (H) comprises a heating tube (2) having a high conductivity; A plurality of heat-insulating tubes (4) coupled to the heat-generating tubes (2); And a heating coil (6) coupled to the insulating fixture (4) and housed in the heating tube (2) and connected to a power line.

상기 발열관체(2)는 내측에 중공을 갖는 대경의 파이프로써, 전단은 막혀있고 후단은 개구부가 형성되어 있으며, 개구부를 통해 발열코일(6) 및 절연 고정구(4)가 삽입되고, 방열기(A)의 결합부(120)에 결합될 수 있는 마개(68)가 포함된 다.The heating tube 2 is a large diameter pipe having a hollow inside and has a front end closed and an opening at the rear end. The heat generating coil 6 and the insulation fixing member 4 are inserted through the opening and the radiator A And a stopper 68 which can be coupled to the engaging portion 120 of the engaging portion 120.

발열관체(2)는 열전달률이 뛰어난 구리, 알루미늄, 스테인레스강 등의 도전성이 좋은 금속으로 형성된다The heating tube 2 is formed of a metal having good conductivity such as copper, aluminum, or stainless steel

상기 발열코일(6)은 니크롬 재질의 철사를 스프링 형상으로 형성한 것이며, 발열코일(6)의 양끝단에 전원선(5)의 (+)극과 (-)극이 연결되며 방열판(100)의 결합부(120)를 막아 밀봉되는 마개(68)의 도전단자에 각기 연결되어 전기가 통할 수 있도록 형성된다.The positive and negative poles of the power line 5 are connected to both ends of the exothermic coil 6 and the heat sink 100 is connected to the negative terminal of the heat generating coil 6, And is electrically connected to each of the conductive terminals of the plug 68 which is sealed by sealing the engaging portion 120 of the connecting portion 120.

본 발명의 실시예에서는 발열코일(6)은 대개 짝수로 구비됨이 바람직하며, 통상 6개 정도가 적당하다.In the embodiment of the present invention, it is preferable that the heat generating coils 6 are provided in an even number, and usually about six are suitable.

상기 절연 고정구(4)는 산화마그네슘을 기본 원료로 하여 소성 가공되는 것으로, 대략 원통형상이되 측면에 발열코일(6)이 수용될 수 있는 절개홈(42)이 형성된다.The insulating fixture 4 is formed by burning magnesium oxide as a base material. The insulating fixture 4 is formed in a substantially cylindrical shape and has a cutout groove 42 on a side surface thereof to receive the heat generating coil 6 therein.

절개홈(42)은 절연 고정구(4)의 외주면에 길이방향으로 절개되어 옆트임 형태로 형성됨으로써 발열코일(6)의 열이 절개홈(42)을 통해 외부로 발산될 수 있도록 하여 발열효율이 더욱 향상될 수 있다. The cutout groove 42 is formed in a lateral shape in the longitudinal direction on the outer circumferential surface of the insulating fixture 4 so that the heat of the heat generating coil 6 can be diverted to the outside through the cutout groove 42, Can be improved.

바람직하게는 절연 고정구(4)는 산화마그네슘과, 산화알루미늄(Al2O3), 이산화규소(SiO2), 산화철(Fe2O3)을 혼합하여 이루어진다. Preferably, the insulating fixture 4 is made by mixing magnesium oxide, aluminum oxide (Al 2 O 3 ), silicon dioxide (SiO 2 ), and iron oxide (Fe 2 O 3 ).

산화마그네슘의 성상은 굵기는 40~200목, 견디는 온도는 500 내지 550℃이다. Magnesium oxide has a thickness of 40 to 200 and a temperature of 500 to 550 ° C.

상기 산화마그네슘에 산화알루미늄(Al2O3), 이산화규소(SiO2), 산화철(Fe2O3)을 혼합한 개선된 산화마그네슘 혼합물은 굵기는 50~325목이고, 내열성이 증대될 수 있다. The improved magnesium oxide mixture in which magnesium oxide is mixed with aluminum oxide (Al 2 O 3 ), silicon dioxide (SiO 2 ), and iron oxide (Fe 2 O 3 ) has a thickness of 50 to 325 and heat resistance can be increased .

일 실시예에 따르면, 절연 고정구(4)를 형성하는 전체 혼합물은 산화마그네슘 30~40중량%와, 산화알루미늄(Al2O3), 이산화규소(SiO2), 산화철(Fe2O3)이 혼합된 혼합물 60~70중량% 혼합된다. According to one embodiment, the entire mixture forming the insulating fixture 4 is composed of 30 to 40 wt% magnesium oxide, aluminum oxide (Al 2 O 3 ), silicon dioxide (SiO 2 ), iron oxide (Fe 2 O 3 ) 60 to 70% by weight of the mixed mixture is mixed.

산화마그네슘이 30중량% 보다 적으면 단열성능이 저하되고, 40중량% 보다 많으면 쉽게 깨지는 단점이 있다. If the amount of the magnesium oxide is less than 30% by weight, the heat insulating performance is deteriorated, and if it is more than 40% by weight, the magnesium oxide is easily broken.

산화알루미늄(Al2O3), 이산화규소(SiO2), 산화철(Fe2O3)이 혼합된 혼합물이 60 중량% 보다 적으면 탄성이 낮아 파손 우려가 높아지며, 70중량% 보다 많으면 탄성이 높아지나 단열성능이 저하된다. When the content of the mixture of aluminum oxide (Al 2 O 3 ), silicon dioxide (SiO 2 ) and iron oxide (Fe 2 O 3 ) is less than 60% by weight, the elasticity is low and the possibility of breakage increases. And insulation performance deteriorates.

상기 산화알루미늄(Al2O3), 이산화규소(SiO2), 산화철(Fe2O3)이 혼합된 혼합물은, 산화알루미늄(Al2O3) 62 내지 72중량%, 이산화규소(SiO2) 27 내지 37중량%, 산화철(Fe2O3) 0.5 내지 1중량%가 혼합되어 이루어지며, 부피비중이 2.40 내지 2.57, 것보기 기공율 15 내지 19(%), 압축강도 83 내지 90(N/㎟)으로서 1700℃에서 소성된 혼합물이다. The aluminum oxide (Al 2 O 3), silicon dioxide (SiO 2), iron oxide (Fe 2 O 3) are mixed mixture is aluminum oxide (Al 2 O 3) 62 to 72% by weight, silicon dioxide (SiO 2) 27 to 37% by weight and iron oxide (Fe 2 O 3 ) in an amount of 0.5 to 1% by weight and having a bulk specific gravity of 2.40 to 2.57, a porosity of 15 to 19% and a compressive strength of 83 to 90 N / Lt; RTI ID = 0.0 > 1700 C. < / RTI >

이들 조성물들을 혼합하여 반죽한 후 몰드에 넣고 가마에서 1350℃~1700℃에서 소성 가공하여 대략 원통형상으로 제작하며, 내열성을 갖는 도자기류의 절연 고정구(4)가 완성된다. These compositions are mixed, kneaded, put into a mold, baked at 1350 ° C. to 1700 ° C. in a kiln to produce a substantially cylindrical shape, and an insulating fixture 4 of a ceramic type having heat resistance is completed.

절연 고정구(4)의 측면에는 발열코일(6)이 삽입되는 절개홈(42)이 길이방향으로 형성되어 이루어지고, 상기 다수의 절연 고정구(4)가 직렬배치되어 상기 발열관체(2)의 길이에 대응하는 길이를 갖도록 형성된다. A plurality of insulating fixtures 4 are arranged in series to form a length of the heating tube 2 so that the length of the heating tube 2 is longer than the length of the insulating tube 4. [ As shown in Fig.

바람직하게는 상기 절연 고정구(4)의 외주면과 상기 발열관체(2)의 내주면 사이에 틈새(26)가 형성되도록 한다. Preferably, a gap 26 is formed between the outer circumferential surface of the insulating fixture 4 and the inner circumferential surface of the heating tube 2. [

즉 절연 고정구(4)의 외경을 발열관체(2)의 내경 보다 작게 형성시킴으로써 틈새(26)가 형성되는 것이다. That is, the outer diameter of the insulating fixture 4 is made smaller than the inner diameter of the heat generating tube 2, the gap 26 is formed.

상기 틈새(26)에는 단열 충진재(8)가 충진된다. The gap (26) is filled with the heat insulating filler (8).

상기 단열 충진재(8)는 산화마그네슘분말이며, 절연 고정구(4)와 발열관체(2) 사이의 틈새(26)에 충분한 양을 채워넣는다.The heat insulating filler 8 is magnesium oxide powder and fills a gap 26 between the insulating fixture 4 and the heat generating tube 2 in a sufficient amount.

따라서 산화마그네슘분말의 특성에 의해 발열코일(6)의 열이 발열관체(2)에 전달되되 지속적이면서 장시간 열이 잔류하게 됨으로써 열효율이 월등히 향상될 수 있다. Accordingly, the heat of the heat generating coil 6 is transmitted to the heat generating tube 2 due to the characteristics of the magnesium oxide powder, and the heat is retained for a long time, thereby improving the thermal efficiency remarkably.

한편 상기 발열관체(2)의 외주면에 외부링(7)이 결합된다. 상기 외부링(7)은 철(Fe)로 된 금속링이 적당하며, 외부링(7)이 방열판(100)의 결합부(120)에 접촉 지지된다. On the other hand, the outer ring (7) is coupled to the outer peripheral surface of the heating tube (2). A metal ring made of iron (Fe) is suitable for the outer ring 7, and the outer ring 7 is held in contact with the coupling portion 120 of the heat sink 100.

외부링(7)은 방열판(100)의 결합부(120)의 중앙부위에 지지되고, 발열관체(2)의 처짐을 방지하기 위해 발열관체(2)의 하중을 견딜 수 있도록 순수한 철 또는 철이 포함된 합금으로 형성된다. The outer ring 7 is supported at a central portion of the coupling portion 120 of the heat sink 100 and includes pure iron or iron so as to withstand the load of the heating tube 2 to prevent deflection of the heating tube 2 Alloy.

또한 상기 발열관체(2)의 외주면에 결합되며 외부링(7)의 양측에 배치되며 방열판(100)의 결합부(120)에 지지되는 열전달부재(300)를 포함한다. And a heat transfer member 300 coupled to the outer circumferential surface of the heating tube 2 and disposed on both sides of the outer ring 7 and supported by the coupling portion 120 of the heat sink 100.

상기 열전달부재(300)는 구리와 아연을 혼합한 다공질금속망이 바람직하다. The heat transfer member 300 is preferably a porous metal net in which copper and zinc are mixed.

다공질금속망은 외부링(7)의 외경과 동일한 외경을 갖도록 형성되며, 결합부(120)의 타측에 꼭맞게 결합되어 지지력을 제공하게 되고, 아울러 발열관체(2)의 열을 다공질금속망을 통해 전달시켜 방열판(100)에 전달하게 된다.The porous metal net is formed to have the same outer diameter as the outer diameter of the outer ring 7 and is tightly fitted to the other side of the coupling part 120 to provide a supporting force. So that the heat is transferred to the heat sink 100.

또한 다공질금속망은 열매체유가 통과할 수 있는 공극을 갖게되므로 열매체유가 발열관체(2)의 외면에 접촉되어 가열될 수 있으면서 방열판(100)의 결합부(120)의 내부에 전체적으로 순환될 수 있다. In addition, since the porous metal net has a cavity through which the heat medium oil can pass, the heat medium oil can be entirely circulated inside the coupling part 120 of the heat sink 100 while being heated by being in contact with the outer surface of the heat generating tube 2.
