태양열 집열판용 진공집열관{VACUUM TUBE TYPE SOLAR ENERGY COLLECTING PIPE}Vacuum heat collecting tube for solar heat collecting plate {VACUUM TUBE TYPE SOLAR ENERGY COLLECTING PIPE}

본 발명은 태양의 복사열을 흡수하는 진공집열관에 관한 것으로, 보다 상세하게는 태양 복사열이 진공집열관에 보다 효과적으로 집열될 수 있도록 하여 열효율을 높인 태양열 집열판용 진공집열관에 관한 것이다.The present invention relates to a vacuum collector tube for absorbing the radiant heat of the sun, and more particularly to a vacuum collector tube for a solar heat collecting plate to increase the heat efficiency by allowing the solar radiation heat to be more effectively collected in the vacuum collector tube.

최근 화석연료의 자원적 한계와 화석연료의 사용에 따른 공해물질의 배출로 오존층의 파괴, 지구온난화 등 그에 따른 각종 환경적 문제가 발생하여 공해물질의 배출이 없고 무한적인 자연 에너지원의 활용이 늘어나고 있는 추세이다.Recently, various environmental problems such as destruction of ozone layer and global warming have occurred due to the emission of pollutants due to the resource limitation of fossil fuels and the use of fossil fuels. There is a trend.

도 1은 종래에 사용되는 일반적인 태양열 집열기를 도시한 사시도를 도시한 것으로, 특히 태양광선의 복사열을 이용하여 물을 데워 난방 또는 온수로 사용하는 태양열 집열기는 태양의 복사열을 흡수하는 진공집열관(20)을 구비하는 집열판(10)과 매니폴드(12)로 구성되어 사용되고 있다.1 is a perspective view showing a conventional solar collector used in the prior art, in particular, the solar collector using the heating or hot water to heat the water by using the radiant heat of sunlight is a vacuum collector tube 20 to absorb the radiant heat of the sun (20) It consists of the heat collecting plate 10 and the manifold 12 provided with ().

상기와 같은 종래의 진공집열관(20)은 내부에 히팅부재가 내장되어 진공집열관(20)에 투입되어 태양 복사열을 전달하며 히팅부재와 매니폴드(12)에 그 에너지가 전달되어 진다.The conventional vacuum heat collecting tube 20 as described above has a heating member embedded therein and is injected into the vacuum collecting tube 20 to transmit solar radiation and its energy is transferred to the heating member and the manifold 12.

그러나 이와 같은 종래의 태양열 집열기는 진공집열관(20)이 태양의 위치에 따라 진공집열관에 투입되는 태양광선이 입사되어 복사열을 전달함과 동시에 대부분의 복사열을 갖는 태양광선은 외부로 바로 반사되어 빠져나가게 되어 열 흡수 효율이 좋지 않으며, 또한 태양의 위치에 따라 진공집열기에 투입되는 태양광선 또한 줄어들어 동일한 열 흡수 효율을 유지하는 것이 불가능 하였다.However, such a conventional solar collector has a solar radiation beam which is introduced into the vacuum collector tube according to the position of the sun to the vacuum collector tube 20 to transmit radiant heat, and at the same time, the solar ray having most of the radiant heat is directly reflected to the outside. The heat absorbing efficiency is not good because it escapes, and the sun rays applied to the vacuum collector are also reduced according to the position of the sun, so that it is impossible to maintain the same heat absorption efficiency.

본 발명은 종래 태양광 집열기에 사용되는 진공집열관의 문제점을 해소하기 위한 것으로, 태양의 위치에 따라 진공집열관에 태양광선이 효율적으로 투입되지 못하는 문제점을 해소하여 태양광선 흡수 효율을 증대시킨 진공집열관을 제공하는데 그 목적이 있다.The present invention is to solve the problem of the vacuum collector tube used in the conventional solar collector, to solve the problem that the solar light is not efficiently injected into the vacuum collector tube according to the position of the sun to increase the sunlight absorption efficiency vacuum The purpose is to provide a heat collecting tube.

상기 본 발명의 목적을 달성하기 위하여, 직경을 달리하는 내,외측 유리관이 중첩되어 일체로 형성되며 그 사이에 진공부가 형성된 진공집열관과, 상기 외측 진공관의 진공부가 형성된 내측면에 길이 방향으로 길게 형성되어 투입되는 빛의 방향에 상관없이 내측 유리관에 집중되어 조사될 수 있도록 빛의 방향을 굴절시키는 외측 유리관의 내주연을 따라 복수의 굴절부가 형성된 태양열 집열판용 진공집열관을 제공한다.In order to achieve the object of the present invention, the inner and outer glass tubes of different diameters are integrally formed and integrally formed, the vacuum collecting tube formed with a vacuum portion therebetween, and the longitudinal direction is long on the inner surface formed with the vacuum portion of the outer vacuum tube Provided is a vacuum collector tube for a solar heat collecting plate having a plurality of refracting portions formed along the inner circumference of the outer glass tube for refracting the direction of light so as to be concentrated and irradiated to the inner glass tube irrespective of the direction of the light is formed and introduced.

본 발명은 태양의 위치에 상관없이 항상 많은 양의 태양 빛을 진공집열관 중 내측 유리관에 집중되게 공급함으로써 진공집열관의 에너지 흡수 효율성을 향상시킴은 물론 반사되어 빠져나가는 태양열을 재차 내측 유리관으로 반사시켜 인입된 태양 빛의 복사열을 보다 효과적으로 흡수할 수 있도록 향상시킨 것이다.The present invention improves the energy absorption efficiency of the vacuum collector tube by supplying a large amount of solar light to the inner glass tube of the vacuum collector tube at all times regardless of the position of the sun, and also reflects the reflected solar heat back to the inner glass tube. This is to improve the absorption of the radiant heat of the incoming solar light more effectively.
