본 발명은 이중 유리관형 태양열 집광장치에 관한 것으로서 더욱 상세하게는 일반온수 및 냉,난방장치의 열원으로 사용하거나 산업체에서 필요로 하는 고온의 작동유체를 생산할 수 있도록 개선된 태양열 집광장치의제공에 관한 것이다.The present invention relates to a double glass tubular solar light concentrating device, and more particularly, to provide a solar heat concentrating device which can be used as a heat source for general hot water and cooling and heating devices or to produce a high temperature working fluid required by an industry. will be.

태양열 집광장치는 전기, 가스 및 기름과 같은 직접적인 별도의 열원을 이용하지 않고서 태양열을 이용하여 일반온수나 낸,난방에 필요한 열원 또는 각종의 산업체에서 필요로 하는 열원인 작동유체를 생산하도록 하는 것이다.The solar heat collecting device is to use the solar heat to produce a working fluid that is a heat source required for general hot water, heating or heating, or a heat source required by various industries, without using a separate direct heat source such as electricity, gas, and oil.

이러한 태양열 집광장치는 평판타입 또는 진공관타입의 것이 많이 사용되고 있는 실정이며 대표적인 예를 도 4와함께 살펴보면 다음과 같다.Such a solar light collecting device is a situation that a lot of flat plate type or vacuum tube type is used, and a representative example will be described with reference to FIG. 4.

반원형상으로 구비되는 케이스(1)의 내측에 반사경(2)을 장착한 집열기(3)를 구비하고, 상기 집열기(3)의 내부에는 유체관(4)을 고정한 집열판(5)을 설치한다.A collector 3 having a reflector 2 is provided inside the case 1 provided in a semicircular shape, and a collector plate 5 having a fluid tube 4 fixed therein is provided inside the collector 3.

상기 케이스(1)의 상부에는 유리(6)를 고정하여 집광장치(10)를 구성하게 된다.The glass 6 is fixed to the upper part of the case 1 to configure the light collecting device 10.

상기와 같은 종래의 집광장치는; 태양광을 집광하지 않고 직사되는 태양열만을 집열하여 작동유체의 온도를 올리게 되므로 작동유체의 온도를 올리는데 상당한 제약이 따르고, 작동유체의 온도를 고온(60도씨이상)으로 할수는 있으나 이렇게 할 경우에는 집열장치의 효율이 20％정도 낮아지는 단점을 가진다.Conventional light collecting device as described above; Since it collects only direct sunlight without condensing sunlight and raises the temperature of the working fluid, there is a significant limitation in raising the temperature of the working fluid, and the working fluid temperature can be high (60 degrees Celsius or more). It has a disadvantage that the efficiency of the heat collecting device is lowered by about 20%.

상기와 같이 작동유체를 고온으로 할 경우 낮아지는 효율로 인하여 충분한 효율을 얻을 수 있도록 작동유체의 온도를 40～50℃정도의 낮은 온도로 밖에 생산할 수 없다.As described above, when the working fluid is heated to a high temperature, the working fluid can only be produced at a low temperature of about 40 to 50 ° C. to obtain sufficient efficiency.

그러므로 종래의 기술로 생산되는 작동유체는 일상적으로 사용할 수 있는 생활용수로 밖에 사용이 불가능하고, 상기와 같이 생활용수로 사용할 경우에는 에너지 절약에는 기여할 수 있으나, 태양열 집광장치의 설치비용에 비하여 그 효율성이 미비한 단점을 가진다.Therefore, the working fluid produced by the conventional technology can only be used as daily water for daily use, and when used as living water as described above, it can contribute to energy saving, but its efficiency is inefficient compared to the installation cost of the solar light concentrator. Has its drawbacks.

이에 본 발명에서는 상기와 같은 문제점들을 해결하기 위하여 발명된 것으로서 태양열을 이용하여 중온까지 작동유체를 상승시킬 수 있는 집광장치를 제공함으로서 집광효율을 증대시켜 일반온수는 물론 냉,난방장치와 산업체에서 필요로 하는 고온의 작동유체를 생산할 수 있도록 함으로서 집광장치의 성능과 품질향상에 기여하면서도 충분한 활용성을 가질 수 있도록 하는데 그 목적을 둔다.Therefore, the present invention has been invented to solve the above problems, by providing a light collecting device that can raise the working fluid to the middle temperature by using solar heat to increase the light collecting efficiency, as well as general hot water, cooling, heating devices and industrial needs By making it possible to produce a high-temperature working fluid, the purpose of the present invention is to contribute to the performance and quality of the light collecting device and to have sufficient usability.

도 1은 본 발명의 기술이 적용된 이중 유리관형 태양열 집광장치를 도시한 사시도, 도 2는 본 발명의 기술이 적용된 이중 유리관형 태양열 집광장치인 도 1의 A - A선을 따라서 취한 단면도, 도 3은 본 발명의 기술이 적용된 이중 유리관형 태양열 집광장치의 요부를 발췌한 단면도로서 함께 설명한다.1 is a perspective view showing a double glass tubular solar light collecting device to which the technique of the present invention is applied, FIG. 2 is a sectional view taken along line A-A of FIG. Is a cross-sectional view showing the main portion of the double glass tubular solar light collecting device to which the technique of the present invention is applied.

본 발명의 기술이 적용되는 집광장치(30)는, 반사율이 높은(98％) 포물면 반사경(31)을 외부유리관(32)으로 구성되는 케이스(33)의 내부에 설치한다.The light concentrating device 30 to which the technique of this invention is applied provides the parabolic reflector 31 with high reflectance (98%) inside the case 33 which consists of the outer glass tube 32. As shown in FIG.

상기 반사경(31)의 상부 양단부는 외측으로 절곡시켜 고정날개(34)를 형성한 후 외부유리관(32)과 고정시켜 유동과 열변형을 방지할 수 있도록 한다.The upper both ends of the reflector 31 is bent outward to form a fixed wing 34 and then fixed with the outer glass tube 32 to prevent flow and heat deformation.

또한, 상기 반사경(31)의 초점위치에는 V자 형상의 노치부(미도시)가 일체로 형성된다.상기 반사경(31)의 초점위치인 노치부에는 태양광 에너지의 흡수율을 극대화 시킬 수 있도록 브랙크롬이 도금된 구리관(35)을 위치시켜 유체가 유동할 수 있도록 한다.In addition, the V-shaped notch portion (not shown) is integrally formed at the focal position of the reflector 31. The notch portion, which is the focal position of the reflector 31, is a black so as to maximize absorption of solar energy. A chrome plated copper tube 35 is positioned to allow fluid to flow.

상기 구리관(35)의 외부에는 구리관(35)이 흡수한 에너지의 손실을 방지할 수 있도록 유리관(36)을 배치하여 집광장치(30)를 구성한다.The light collecting device 30 is configured by disposing a glass tube 36 outside the copper tube 35 so as to prevent loss of energy absorbed by the copper tube 35.

상기와 같은 본 발명의 집광장치(30)는;The light collecting device 30 of the present invention as described above;

반사경(31)의 초점부위인 노치부에 유체가 흐르는 구리관(35)을 배치하고 그 외부를 유리관(36)으로 보호하여 구리관(35)이 흡수한 태양광에너지의 손실을 방지하게 된다.특히, 구리관(35)의 표면에는 블랙크롬을 도금하여 태양광에너지의 흡수효율을 증대시키게 됨으로서 구리관(35)을 통하여 유동하는 유체의 온도를 고온(약70～120℃)상태로 생산할 수 있게 된다.The copper tube 35 through which the fluid flows is disposed in the notch, which is the focal point of the reflector 31, and the outside thereof is protected by the glass tube 36 to prevent loss of solar energy absorbed by the copper tube 35. In particular, the surface of the copper pipe 35 is plated with black chromium to increase the absorption efficiency of solar energy, so that the temperature of the fluid flowing through the copper pipe 35 can be produced at a high temperature (about 70 to 120 ° C.). Will be.

그리고, 집광장치(30)가 원통형의 외부유리관(32) 내부에 포물면 반사경(31)을 고정시키고, 다시 유리관(36)의 내부에 반사경(31)의 초점위치인 노치부에 구리관(35)을 배치함으로서 태양광을 추적하지 않고서도 태양광을 효율적으로 집속하여 구리관(35)이 흡수할 수 있게된다.또한, 상기 반사경(31)의 상부 양단부를 외측으로 절곡시켜 형성되는 고정날개(34)는 외부유리관(32)에 고정됨으로써 반사경이 외부유리관(32)의 내측에서 유동되는 것을 방지하고, 반사경에 흡수되는 열을 외부유리관(32)에 분산시키는 역할을 수행하여 열변형을 방지한다.계속하여, 상기 외부유리관(32)과 반사경(31)은 전체가 접합된 상태가 아니기 때문에 열팽창 차이에 의한 열변형의 유발은 염려할 필요가 없다.그리고, 상기 반사경(31)의 초점위치에는 V자 형상의 노치부(미도시)가 일체로 형성되어 반사경의 초점을 찾기위해 별도의 위치결정 작업이 불필요 하다.Then, the light collecting device 30 fixes the parabolic reflector 31 inside the cylindrical outer glass tube 32, and again the copper tube 35 in the notch which is the focal position of the reflector 31 inside the glass tube 36. By arranging the laser beam, the copper pipe 35 can be absorbed efficiently by focusing sunlight without tracking sunlight. Further, the fixed blade 34 formed by bending the upper both ends of the reflector 31 to the outside ) Is fixed to the outer glass tube 32 to prevent the reflector from flowing inside the outer glass tube 32, and serves to disperse heat absorbed by the reflector in the outer glass tube 32 to prevent thermal deformation. Subsequently, since the outer glass tube 32 and the reflecting mirror 31 are not all bonded together, there is no need to worry about the occurrence of thermal deformation due to the difference in thermal expansion. Notch part (not shown) of the shape is work It is formed into a sieve so that no separate positioning work is needed to find the focus of the reflector.

상기와 같은 본 발명은 이중의 유리관(외부유리관과 유리관)내부에 구리관을 설치하여 고비용의 진공관을 이용하지 않으면서도 열손실을 최소화 하여 높은 온도의 작동유체를 생산할 수 있어 시스템 전체의 효율성이 높은 장점을 가지게 된다.The present invention as described above is to install a copper pipe inside the double glass tube (outer glass tube and glass tube) to minimize the heat loss without the use of expensive vacuum tube to produce a high temperature working fluid high efficiency of the whole system You have an advantage.

상기와 같이 생산된 고온의 작동유체는 일반온수는 물론 냉,난방에 필요한 열원으로의 사용은 물론, 각종 산업체에서 필요한 작동유체로 충분한 활용성을 가지는 것이다.The high temperature working fluid produced as described above has sufficient utility as a working fluid required for various industries as well as use as a heat source required for cooling and heating as well as general hot water.
