도 2 및 도 3은 본 발명의 일 실시예에 따른 태양전지 발전기에서 방열구조를 설명하는 도면이다.2 and 3 are views illustrating a heat dissipation structure in a solar cell generator according to an embodiment of the present invention.
도 2 및 도 3에 나타난 바와 같이, 본 실시예의 지지패널(20)은 태양을 향하는 전면이 태양전지패널(10)의 타면을 지지한다. 이에 따라, 지지패널(20)의 후면 및 인접한 영역에는 태양열이 도달하지 않는 그늘이 형성되어 전면에 비하여 낮은 온도를 가지는 영역이 형성되며, 지지패널(20)의 후면에는 방열을 수행하는 히트파이프(30)가 결합된다.As shown in Figure 2 and 3, the support panel 20 of the present embodiment supports the other surface of the solar cell panel 10 is the front surface facing the sun. Accordingly, a shade which does not reach solar heat is formed on the rear side and the adjacent region of the support panel 20 to form a region having a lower temperature than the front side, and a heat pipe that radiates heat on the rear side of the support panel 20. 30) are combined.
히트파이프(30)는 지지패널(20)에 결합되어 지지패널(20)에서 전달된 열을 방열하는 부분이다. 본 실시예의 방열부재는 상대적으로 온도가 낮은 지지패널(20)의 후면에 결합되어 온도차를 이용하여 열을 방출할 수 있다. The heat pipe 30 is coupled to the support panel 20 to radiate heat transferred from the support panel 20. The heat dissipation member of the present embodiment may be coupled to the rear surface of the support panel 20 having a relatively low temperature to release heat by using a temperature difference.
특히, 본 실시예의 히트파이프(30)로는 작동유체가 주입되는 세관형 히트파이프가 사용되어서 신속한 방열이 이루어질 수 있다. 구체적으로, 진동세관형 히트파이프가 사용될 수 있다.In particular, the heat pipe 30 of the present embodiment can be a rapid heat dissipation by using a tubular heat pipe to which the working fluid is injected. Specifically, a vibrating tubular heat pipe may be used.
진동세관형 히트파이프는 세관(32) 내부에 작동유체(34)와 기포(36)가 소정 비율로 주입된 후 세관(32) 내부가 외부로부터 밀폐되는 구조를 가진다. 이에 따라, 진동세관형 히트파이프는 기포(36) 및 작동유체(34)의 부피팽창 및 응축에 의하여 열을 잠열 형태로 대량으로 수송하는 열전달 사이클을 가진다. The vibrating tubular heat pipe has a structure in which the working fluid 34 and the bubble 36 are injected into the tubule 32 at a predetermined ratio and the inside of the tubule 32 is sealed from the outside. Accordingly, the vibrating tubular heat pipe has a heat transfer cycle for transporting a large amount of heat in latent form by volume expansion and condensation of the bubble 36 and the working fluid 34.
열전달 메카니즘을 살펴보면, 열을 흡수한 흡열부(30a)에서는 흡수된 열량만큼 핵비등(Nucleate Boiling)이 일어나면서 흡열부(30a)에 위치된 기포(36)들이 부피 팽창을 하게 된다. 이때 세관(32)은 일정한 내부 체적을 유지하므로, 흡열부(30a)에 위치된 기포(36)들이 부피 팽창을 한 만큼 열을 발산하는 방열부(30b)에 위치된 기포(36)들은 수축하게 된다. 따라서 세관(32) 내의 압력 평형상태가 붕괴되면서, 세관(32) 내에서 작동유체(34) 및 기포(36)의 진동을 포함한 유동이 수반되고, 이에 따라 기포(36)의 체적 변화에 의한 온도의 승강에 의하여 잠열 수송이 이루어짐으로써 방열이 수행된다.Looking at the heat transfer mechanism, the heat absorbing portion (30a) is nucleate boiling (Nucleate Boiling) occurs by the amount of heat absorbed bubbles (36) located in the heat absorbing portion (30a) is the volume expansion. At this time, since the tubule 32 maintains a constant internal volume, the bubbles 36 located in the heat dissipating part 30b dissipating heat as much as the bubbles 36 located in the heat absorbing part 30a have a volume expansion so that they contract. do. Accordingly, as the pressure equilibrium in the tubule 32 collapses, the flow including the vibration of the working fluid 34 and the bubbles 36 in the tubule 32 is accompanied, and thus the temperature due to the volume change of the foam 36 is accompanied. The heat dissipation is carried out by the latent heat transportation by lifting and lowering.
여기서, 진동세관형 히트파이프는 열전도도가 높은 구리, 알루미늄 등의 금속 소재로 이루어진 세관을 포함할 수 있다. 이에 따라, 열을 빠른 속도로 전도 받음과 아울러 그 내부에 주입된 기포(36)의 체적변화를 빠르게 유발할 수 있다.Here, the vibrating capillary heat pipe may include a capillary tube made of a metal material such as copper and aluminum having high thermal conductivity. Accordingly, while conducting heat at a high speed, the volume change of the bubble 36 injected therein can be quickly induced.
또한, 세관(32)으로 형성된 히트파이프(30)는 부피 대비 넓은 열전달면적을 가질 수 있으므로, 대량의 열을 빠르게 흡수 또는 방출할 수 있다. 그리고, 열전달의 방향성에 대한 제약이 없어서 어떠한 방향으로든 열전달이 우수하며 배치가 자유로운 장점도 있다.In addition, since the heat pipe 30 formed of the tubule 32 may have a large heat transfer area to volume, it may quickly absorb or release a large amount of heat. In addition, since there is no restriction on the direction of heat transfer, heat transfer is excellent in any direction, and there is an advantage in that the arrangement is free.
또한, 진동세관형 히트파이프는 별도의 동력을 공급하지 않고도 방열을 수행함으로써, 구조가 간단하고 설치 및 유지보수가 용이한 방열구조를 형성할 수 있다.In addition, the vibrating tubular heat pipe performs heat dissipation without supplying additional power, thereby forming a heat dissipation structure having a simple structure and easy installation and maintenance.
한편, 진동세관형 히트파이프의 연통구조는 개루프(open loop)와 폐루프(close loop) 모두 가능하다. 또한, 진동세관형 히트파이프가 복수 일 때, 진동세관형 히트파이프의 전부 또는 일부는 이웃하는 진동세관형 히트파이프와 연통될 수 있다. 이에 따라, 복수의 진동세관형 히트파이프는 설계상 필요에 따라 전체적으로 개루프 또는 폐루프 형상을 가질 수도 있다.On the other hand, the communication structure of the vibrating tubular heat pipe can be both an open loop (close loop) and (close loop). In addition, when there are a plurality of vibrating tubular heat pipes, all or part of the vibrating tubular heat pipe may be in communication with a neighboring vibrating tubular heat pipe. Accordingly, the plurality of vibrating capillary heat pipes may have an open loop or closed loop shape as a design necessity.
도 2 및 3에 나타난 바와 같이, 본 실시예에서 진동세관형 히트파이프는 나선형 구조의 방열루프를 형성한다. 이에 따라, 진동세관형 히트파이프에서 지지패널(20)과 결합된 흡열부(30a)와 지지패널(20)에서 이격되어 열을 방출하는 방열부(30b)가 반복적으로 형성되어서, 흡열부(30a)와 방열부(30b) 사이에 짧은 열전달 경로를 통하여 신속하게 열을 방출할 수 있다. 또한, 방열루프의 나선 사이로는 공기가 자유롭게 통과할 수 있으므로, 방열에 필요한 높은 통기성도 확보할 수 있다.As shown in Figures 2 and 3, the vibrating tubular heat pipe in this embodiment forms a heat radiation loop of a spiral structure. Accordingly, the heat absorbing portion 30a coupled to the support panel 20 and the heat dissipating portion 30b spaced apart from the support panel 20 to release heat in the vibrating tubular heat pipe are repeatedly formed, thereby absorbing the heat absorbing portion 30a. ) And the heat dissipation portion 30b can be quickly released through a short heat transfer path. In addition, since air can pass freely between the spirals of the heat dissipation loop, high ventilation required for heat dissipation can be ensured.
더불어, 경량의 진동세관형 히트파이프를 이용하여 방열을 수행하므로, 종래의 방열구조에 비해 무게를 현저하게 줄일 수 있으며 이에 따라 구조적인 안정성을 확보할 수 있다.In addition, since heat radiation is performed using a lightweight vibrating tubular heat pipe, the weight can be remarkably reduced compared to the conventional heat dissipation structure, thereby ensuring structural stability.
도 4는 본 발명의 다른 실시예에 따른 태양전지 발전기를 나타낸 사시도이고, 도 5는 본 발명의 다른 실시예에 따른 태양전지 발전기에서 방열구조를 설명하는 도면이다.4 is a perspective view showing a solar cell generator according to another embodiment of the present invention, Figure 5 is a view for explaining a heat radiation structure in the solar cell generator according to another embodiment of the present invention.
도 4 및 도 5에 도시된 바와 같이 본 실시예에 따른 태양전지 발전기의 경우, 상술한 바와 같이 흡열부(30a)와 방열부(30b)를 반복적으로 형성하는 나선형 구조의 방열루프가 환형으로 말아짐으로써, 히트파이프(30)가 전체적으로 환형 구조를 이루게 된다.As shown in FIGS. 4 and 5, in the solar cell generator according to the present embodiment, the heat dissipation loop having a spiral structure repeatedly forming the heat absorbing portion 30a and the heat dissipating portion 30b as described above is rolled in an annular shape. As a result, the heat pipe 30 has an annular structure as a whole.
이에 따라 흡열부(30a) 및 방열부(30b) 각각은 이러한 환형 구조의 중심축을 기준으로 방사상으로 배치될 수 있다. 다시 말해, 흡열을 수행하는 흡열부(30a)와 방열을 수행하는 방열부(30b)가 환형 구조의 중심축을 중심으로 방사상으로 배치되며, 이에 따라 방열에 필요한 공기의 유동이 보다 자유롭게 되어 보다 높은 효율의 방열이 이루어질 수 있다.Accordingly, each of the heat absorbing portion 30a and the heat dissipating portion 30b may be disposed radially with respect to the central axis of the annular structure. In other words, the heat absorbing portion 30a for performing heat absorption and the heat radiating portion 30b for radiating heat are disposed radially around the central axis of the annular structure, thereby allowing more free flow of air for radiating heat, resulting in higher efficiency. The heat dissipation can be made.
그리고 이러한 히트파이프(30)와 지지패널(20)의 후면 사이에는 예를 들어 구리 등으로 이루어진 판형 구조의 서멀베이스(35)가 개재될 수 있다. 즉, 히트파이프(30)의 흡열부(30a)에는 서멀베이스(35)가 부착될 수 있으며, 이와 같이 히트파이프(30)가 부착된 서멀베이스(35)를 지지패널(20)의 후면에 부착함으로써 보다 용이하게 히트파이프(30)를 지지패널(20)의 후면에 결합할 수 있게 된다.In addition, a thermal base 35 having a plate structure made of, for example, copper may be interposed between the heat pipe 30 and the rear surface of the support panel 20. That is, the thermal base 35 may be attached to the heat absorbing portion 30a of the heat pipe 30, and the thermal base 35 to which the heat pipe 30 is attached is attached to the rear surface of the support panel 20. By doing so, the heat pipe 30 can be more easily coupled to the rear surface of the support panel 20.
