본발명은 태양열 보일러 시스템에 있어서, 내부에 난방부재가 삽입설치되어 난방배관인 진공관 내 온수의 온도를 상승시킬 수 있는 난방부재가 설치된 태양열 진공관에 관한 것이다.The present invention relates to a solar vacuum tube in which a heating member is installed in a solar boiler system, and a heating member is inserted therein to increase the temperature of hot water in the vacuum tube.

일반적으로 태양열을 이용하여 냉수를 온수로 전환시켜 사용하는 온수시스템은 등록특허공보 10-1051760호에 종래기술로 기재된 바와 같이, 냉수를 파이프내로 유입시킨 뒤이 파이프를 태양열로 가열하여 파이프내의 냉수가 데워지면 이 온수를 축열탱크에 담아두었다가 사용하는 기본원리로 구성되어 지지만, 집열과 축열, 열 교환 등에 있어서 얼마나 효율성이 높으냐에 따라 시스템의 성능이나 실제적용에의 성공여부가 판가름되므로 태양열 집열부분에 대한 기술개발이 보다 폭넓고 깊게 행하여져왔다.In general, a hot water system that converts cold water into hot water using solar heat is described in the prior art in Korean Patent Publication No. 10-1051760, and after the cold water is introduced into the pipe, the pipe is heated by solar heat to heat the cold water in the pipe. The ground consists of the basic principle of storing and using hot water in the heat storage tank.However, the efficiency of the system or the success of the application depends on how efficient the heat storage, heat storage and heat exchange are. Technology development has been done more broadly and deeply.

진공관형 태양열 집열기술은 태양의 복사열로 물을 데워서 보관하는 이른바 진공보온병(Thermo Flask)의 원리를 응용한 것으로, 이중벽(Double Skin) 사이공간을 진공 단열처리 하여 대류나 열전도로 인한 열손실을 최소화시킴에 따라 오랫동안 온수를 보관하도록 사용되어 왔다.Vacuum tube solar heat collection technology applies the principle of the so-called Thermo Flask, which heats and stores water by the sun's radiant heat, and minimizes heat loss due to convection or heat conduction by vacuum-insulating the space between double skins. It has been used to store hot water for a long time.

여기서, 태양열 집열기는 상기 종래기술에 기재된 바와 같이, 외형적인 구조와 적용성을 고려하여 평판형과 진공관형의 태양열 집열기로 구분되며, 유리튜브를 (단일)진공관의 형태로 사용하는 방법이 개발되어서 유리튜브 내부에 집열판이 장착된 히트파이프를 삽입시키고 유리튜브의 상단으로 히트파이프를 돌출 설치시킨 상태에서 금속재질의 마개로 밀폐시키고 그 내부를 진공처리하여 집열판 표면에서 집열된 태양열을 대류에 의한 외부로의 열손실을 차단시키는 것이 있으며, 두 개의 유리튜브를 이중진공관의 형태로 사용하는 방법의 진공관형 태양열 집열기 등도 있다. 그러나, 이경우 매체(물)를 집열튜브 내에 직접 채워서 가열하는 방식은 일부에서 동절기등의 혹한기에 동파 문제나, 태양열에 의해 가열된 집열튜브내에 물이 갑자기 유입되면 열응력에 의해 열쇼크 현상이 발생하여 집열튜브가 파손되는 문제가 발견되고 있으며 또한, 튜브가 파손되면 축열조의 물이 파손된 튜브로 누수되는 위험성이 있다.Here, the solar collector is classified into a flat plate and a vacuum tube solar collector in consideration of its external structure and applicability, as described in the related art, and a method of using a glass tube in the form of a (single) vacuum tube has been developed.

However, in this case, the method of heating the medium (water) by filling it directly into the heat collecting tube is a problem of freezing in cold weather such as winter season, or when the water suddenly flows into the heat collecting tube heated by solar heat, thermal shock occurs due to thermal stress. There is a problem that the collecting tube is broken, and if the tube is broken, there is a risk that water in the heat storage tank leaks into the broken tube.

The present invention will be described in detail with reference to the accompanying drawings. 1 is a heating member installation photo of the solar vacuum tube is installed the present invention heating member, Figure 2 is a heating device installation detailed picture of Figure 1, Figure 3 is a perspective view of a rectangular bar heating member of the solar vacuum tube is installed the present invention, Figure 4 Is a perspective view of a trapezoidal heating member of a solar vacuum tube with the present invention heating member, Figure 5 is a cross-sectional view of the concave groove formed in the rectangular bar heating member of the solar vacuum tube with the present invention heating member, Figure 6 is a solar heat installation with the present invention heating member Sectional view in which the recessed groove is formed in the trapezoidal heating member of the vacuum tube, Figure 7 is a cross-sectional view of a rectangular bar heating member integrally integrated with the inner member and the outer member in the solar vacuum tube equipped with the present invention heating member, Figure 8 is the present invention is installed In the solar vacuum tube, the inner and outer members are integrally formed in a cross section of a quadrilateral heating element.

본발명 난방부재가 설치된 태양열 진공관은 태양열에 의하여 물을 데워서 난방을 하는 태양열 시스템에 설치되는 태양열 진공관(200)에 있어서, 상기 진공관(200) 내부에는 난방부재(100)가 설치되는 것이다.     The solar vacuum tube provided with the present invention heating member is a solar vacuum tube 200 installed in a solar system that heats water by solar heat, and the heating member 100 is installed inside the vacuum tube 200.

그리고 상기 난방부재(100)는 단면이 사각형인 사각막대이며, 상기 사각막대 양 끝단에는 철판과 같은 금속재질의 탄성이 있는 고정대(120)가 설치된다.곧, 상기 고정대(120)가 진공관(200)내부에 탄성력에 의해 긴밀하게 고정되는 것으로, 상기 고정대(120)는 가로, 세로 밴드(121, 122)가 사각막대의 양끝단에서 십자형으로 교차하며 내부로 굴곡되며 난방부재의 양끝단을 파지하며, 동시에 고정대(120)의 가로, 세로 밴드(121, 122)의 측면 굴곡된 부위 가 진공관(200) 내면에 탄성력에 의해 긴밀하게 이탈되지 않게 고정된다.In addition, the heating member 100 is a rectangular bar having a rectangular cross section, and both ends of the rectangular bar are provided with fixing rods 120 having elasticity made of metal such as iron plates. In other words, the fixing rod 120 includes a vacuum tube 200. It is tightly fixed by the elastic force inside the, the holder 120 is horizontal, vertical bands (121, 122) crosses at both ends of the square bar crosswise and bent to the inside and grips both ends of the heating member At the same time, the side bent portions of the horizontal and vertical bands 121 and 122 of the holder 120 are fixed to the inner surface of the vacuum tube 200 so as not to be intimately separated by elastic force.

상기와 같이 삽입설치된 난방부재에 의해 진공관 내부의 물흐름 구간을 나누게 되므로, 진공관 내부에서 태양열에 의해 가열되어 수온이 높은 부위와 수온이 상대적으로 낮은 부위가 서로 혼합되어 흐름을 방해하여 물 및 온도의 흐름이 원활하지 않아 온수의 온도를 떨어뜨리는 현상을 방지하게 된다.Since the water flow section inside the vacuum tube is divided by the heating member inserted as described above, the portion of the high temperature and the relatively low water temperature are mixed with each other by being heated by solar heat inside the vacuum tube to prevent the flow of water and the temperature. The lack of flow prevents the warming of the water.

한편, 본발명의 상기 난방부재(100)는 단면이 사다리꼴형인 사다리꼴막대로 형성할 수 있다.On the other hand, the heating member 100 of the present invention can be formed into a trapezoidal rod having a trapezoidal cross section.

Therefore, when the heating member 100 is inserted into the vacuum tube 200, the elastic outer member is tightly fixed to the inside of the vacuum tube 200. In this case, the shape of the heating member is a square bar or trapezoid bar.

한편, 본발명에서 난방부재를 내외부를 일체로 하는 방법에 대해 기재하면, 인서트 사출방법을 이용하는 것으로 상기 난방부재의 내부부재를 먼저 고밀도폴리에틸렌(HDPE) 재질로 사출성형하는 것으로, 사각형 또는 사다리꼴 단면 형상의 금형 내부에 가열용융된 수지를 넣고 사출성형하여 사각막대 또는 사다리꼴 막대형상으로 제작하고, 이후 상기 사출성형된 내부부재를 별개의 금형 내에 안치한 후, 저밀도폴리에틸렌(LDPE) 또는 실리콘 재질 가열용융수지를 인서트 사출하여 내부부재 및 외부부재가 일체로 성형되는 것이다.Meanwhile, in the present invention, a method for integrating the heating member into the inside and the outside is described by using an insert injection method, wherein the inner member of the heating member is first injection-molded with a high density polyethylene (HDPE) material, and has a rectangular or trapezoidal cross-sectional shape. Heat-molded resin was put into the mold of the mold and injection molded to form a rectangular bar or trapezoidal rod shape. Then, the injection-molded inner member was placed in a separate mold, and then a low density polyethylene (LDPE) or silicone hot melt resin was prepared. By insert injection, the inner member and the outer member are molded integrally.

한편, 상기 난방부재의 외면은 오목홈을 형성하여 유체의 와류현상을 감소하게 할 수 있다.On the other hand, the outer surface of the heating member may form a concave groove to reduce the vortex phenomenon of the fluid.

따라서 본발명은 태양열 난방시스템의 진공관 내부에 난방부재를 삽입설치하여 진공관 내 고온수와 저온수를 명확히 구분하여 흐르게 하여 물 및 온도의 흐름을 원활하게 하여 결과적으로 진공관 내의 온수의 온도를 상승시키고 에너지 효율을 높이는 현저한 효과가 있다.     Therefore, the present invention inserts a heating member inside the vacuum tube of the solar heating system so that the hot water and the cold water in the vacuum tube are clearly distinguished and flows to facilitate the flow of water and temperature, thereby raising the temperature of the hot water in the vacuum tube and increasing energy. There is a remarkable effect of increasing the efficiency.
