Description
본 발명은 태양열 집열기에 관한 것으로서, 더욱 상세하게는 열손실을 최소화하여 집열성능을 향상시킬 수 있는 태양열 집열기에 관한 것이다.The present invention relates to a solar heat collector, and more particularly, to a solar heat collector capable of improving heat collecting performance by minimizing heat loss.
일반적으로 태양열 집열기는 태양의 직사광 또는 산란광을 열에너지로 전환시키는 장치이며, 태양열 집열시스템을 구성하는데 있어서 가장 핵심적인 부분이다. 집열기는 형상이 고정되고 건물의 옥상 등 제한된 장소에 설치되는 집열기(이하 편의상 '고정식 집열기') 및 집열기의 설치 및 해체가 자유로워 집열기의 설치가 특정장소에 한정되지 않는 집열기(이하 편의상 '비고정식 집열기')가 있다. 태양열 집열기의 집열매체로는 주로 공기 또는 물이 사용된다.In general, a solar heat collector is a device that converts direct sunlight or scattered light into heat energy, and is the most important part in constructing a solar heat collection system. The collector is fixed in shape and installed in a limited place such as the roof of the building (hereinafter referred to as'fixed collector' for convenience) and the collector is free to install and disassemble, so the collector is not limited to a specific place (hereinafter referred to as'non-fixed' for convenience) Collector'). Air or water is mainly used as a heat collecting medium for the solar heat collector.
도 1을 참조하여, 종래의 공기를 집열매체로 사용하는 고정식 집열기(100)를 설명하면 다음과 같다.Referring to Figure 1, a description of the fixed collector 100 using the conventional air as a heat collecting medium is as follows.
케이스(110)의 내부에 열매체인 공기가 흐르는 집열덕트(120)가 배열되고, 공기의 출입을 위하여 유입구와 유출구가 마련된다. 집열덕트(120)는 알루미늄과 같이 열전달 효율이 좋은 재질을 사용하여 케이스(110) 내부에 지그재그로 절곡되어 형성되어 있다. 집열기(100)의 집열면은 투명한 유리 또는 폴리카보네이트 등으로 덮여 있다. 집열기(100)는 지면에 대하여 일정각도로 기울여 설치되는 것이 보통이나 도 1과 같이 반사판(130)을 둘 경우 지면에 수직이 되도록 설치되기도 한다.Inside the case 110, a heat collecting duct 120 through which air, which is a heating medium, flows is arranged, and an inlet and an outlet are provided for air in and out. The heat collecting duct 120 is formed by bending in a zigzag manner inside the case 110 using a material having good heat transfer efficiency, such as aluminum. The heat collecting surface of the heat collector 100 is covered with transparent glass or polycarbonate. The collector 100 is usually installed at a certain angle with respect to the ground, but is also installed to be perpendicular to the ground when the reflector 130 is placed as shown in FIG. 1.
이러한 고정식 태양열 집열기를 이용한 집열과정을 설명하면 다음과 같다. 태양의 직사광, 반사광 또는 산란광이 유리덮개를 통과하여 집열덕트(120)에 닿으면 열에너지로 전환된다. 또한 일부의 태양광은 온실효과로 케이스(110) 내부의 공기를 가열하고 가열된 공기의 대류와 전도에 의해 열이 집열덕트(120)에 전달된다. 집열덕트(20)에 전달된 열은 상기 집열덕트(120) 내부의 공기를 가열한다. 가열된 공기는 유출구를 통하여 집열기(100)를 빠져나가며, 필요에 따라 난방이나 온수제조의 용도로 사용된다.The process of collecting the heat using the fixed solar heat collector is as follows. When direct sunlight, reflected light or scattered light of the sun passes through the glass cover and contacts the heat collection duct 120, it is converted into thermal energy. In addition, some sunlight heats the air inside the case 110 due to the greenhouse effect, and heat is transferred to the heat collection duct 120 by convection and conduction of the heated air. The heat transferred to the heat collecting duct 20 heats the air inside the heat collecting duct 120. The heated air exits the collector 100 through the outlet, and is used for heating or hot water production if necessary.
그러나 이러한 고정식 태양열 집열기는 제조비용이 고가이며, 형상이 고정되어 있으므로 제한된 장소에 설치해야 하며, 집열기를 특정장소에 설치한 다음 다른 장소로 이동시키는 것이 자유롭지 못한 문제점이 있었다. 또한 집열기의 설치와 해체가 자유롭지 못하다.However, these fixed solar collectors are expensive to manufacture and must be installed in a limited place because the shape is fixed, and there is a problem in that it is not free to move the collector to another place after installing the collector. Also, it is not possible to install and disassemble the collector.
상술한 고정식 태양열 집열기의 단점을 해결하기 위한 것이 비고정식 집열기이다. 비고정식 집열기는 한국공개특허공보 제10-2008-0089954, 한국공개특허공보 제10-2012-0046945 등에 제안되어 있다.The non-fixed collector is intended to solve the above-mentioned disadvantages of the fixed solar collector. Non-fixed collectors are proposed in Korean Patent Publication No. 10-2008-0089954, Korean Patent Publication No. 10-2012-0046945, and the like.

태양광은 보호막(240), 보온부(220)을 투과하여 직접 집열부(210)로 가거나(A), 또는 반사를 거듭하여 집열부(210)로 가게된다(B, C, D).The sunlight passes through the protective film 240 and the warming part 220 and goes directly to the heat collecting part 210 (A), or is repeatedly reflected and goes to the heat collecting part 210 (B, C, D).
도 3을 참조하여, 종래의 비고정식 태양열 집열기의 문제점을 설명한다.Referring to FIG. 3, the problem of the conventional non-fixed solar heat collector will be described.
태양열 집열기(200)는 궁극적으로 집열부(210)의 내부에 있는 집열매체로 열을 집열하는 것이다. 따라서, 집열성능을 최대화하기 위해서는 집열매체로 집열을 최대화하는 것뿐만 아니라, 집열매체에 집열된 열이 다시 집열매체에서 방출되어 열이 손실되는 것을 최소화하여야 한다.The solar heat collector 200 ultimately collects heat with a heat collecting medium inside the heat collecting part 210. Therefore, in order to maximize the heat collection performance, it is necessary to minimize not only maximizing heat collection with the heat collecting medium, but also heat dissipated from the heat collecting medium and heat loss.
그런데, 종래의 태양열 집열기(200)에서는, 집열매체에서 다시 외부로 방출되는 열이 많다는 문제가 있다. 그 이유를 설명하면 다음과 같다.However, in the conventional solar heat collector 200, there is a problem that there is a lot of heat discharged from the heat collecting medium to the outside again. The reason is as follows.
집열부(210) 내부의 온도(T1), 보온부(220) 내부의 온도(T2), 보호막(240) 내부의 온도(T3) 및 외부의 온도(T4)는 물론 각 위치에 따라 다를 것이지만, 정성적 관점에서 보면 대략 T2 > T3 > T4 이다. (도 3에서는 각각의 온도를 정성적으로 비교하기 위하여, 편의상 지면에서 수직한 방향으로 각각의 온도를 표시한 것이다.)The temperature (T1) inside the heat collecting part 210, the temperature (T2) inside the heat keeping part 220, the temperature (T3) inside the protective film 240, and the outside temperature (T4) will be different depending on each location, of course, From a qualitative point of view, approximately T2> T3> T4. (In FIG. 3, in order to qualitatively compare each temperature, for convenience, each temperature is displayed in a vertical direction from the ground.)
이러한 온도 차이에 의하여, 집열부(210)에 집열된 열이 보온부(220) 및 보호막(240)를 통하여 외부로 열전달되어 열손실이 발생하는 것을 피하기는 어렵다. 그러나 이러한 온도차의 의한 열손실을 피할 수는 없어도 열손실을 최소화하는 것이 바람직하다.Due to this temperature difference, it is difficult to avoid heat generated by heat collected in the heat collecting part 210 being transferred to the outside through the heat keeping part 220 and the protective film 240. However, it is desirable to minimize heat loss even if heat loss due to the temperature difference cannot be avoided.
그런데, 도 3에 도시한 바와 같이, 종래의 태양열 집열기에서는, 보호막(240)의 일부 즉 상측은 보온부(220)에 직접 접촉하고 있다. 보호막(240)과 보온부(220)가 직접 접촉한 부분에서는 온도차는 (T2 - T4)이다. 그런데 보온부(220)와 보호막(240)이 직접 접촉하지 않은 부분의 온도차는 (T3 - T4)이다. 즉 보호막(240)과 보온부(220)가 직접 접촉한 부분에서는 온도차가 상대적으로 크다. 따라서 이 부분을 통한 열손실이 특히 크다는 문제가 있다. 또한 열손실의 크면 태양열 집열기의 집열 효율도 저하한다는 문제가 있다.By the way, as shown in FIG. 3, in the conventional solar heat collector, a part of the protective film 240, that is, the upper side, is in direct contact with the heat insulating part 220. The temperature difference is (T2-T4) in a portion where the protective film 240 and the thermal insulation part 220 are in direct contact. However, the temperature difference between the portion where the insulating part 220 and the protective film 240 does not directly contact is (T3-T4). That is, the temperature difference is relatively large in a portion where the protective film 240 and the thermal insulation part 220 are in direct contact. Therefore, there is a problem that heat loss through this part is particularly large. In addition, if the heat loss is large, there is a problem that the heat collection efficiency of the solar heat collector also decreases.

도 4를 참조하여, 본 발명에 따른 태양열 집열기의 실시예를 설명한다.4, an embodiment of a solar heat collector according to the present invention will be described.
본 실시예의 구성요소 중에 종래 기술과 동일한 구성요소는 종래 기술과 동일한 명칭 및 도면 번호를 사용한다. 또한 설명의 번잡을 피하기 위하여, 본 실시예의 구성요소 중에 종래 기술과 실질적으로 동일한 구성요소의 상세한 설명은 생략하며, 본 실시예의 주제와 관련된 내용에 한정하여 설명한다.Among the components of this embodiment, the same components as in the prior art use the same names and drawing numbers as in the prior art. In addition, in order to avoid the complexity of the description, detailed descriptions of the components substantially the same as those of the prior art among the components of the present embodiment are omitted, and description will be limited to contents related to the subject matter of the present embodiment.
본 실시예에서도, 유연 재질의 집열부(210)를 둘러싸도록, 유연 재질의 보온부(220)가 구비된다. 보온부(220)의 일부에는 집열부(210) 주위의 태양광을 상기 집열부(210)로 반사시키는 유연 재질의 제1반사부(230)가 구비될 수 있다. 또한, 지면에는 기저막(250)이 구비될 수 있으며, 상기 기저막(250)의 일부에는 반사부(260)가 구비될 수 있다.Also in this embodiment, the heat insulating part 220 of the flexible material is provided to surround the heat collecting part 210 of the flexible material. A first reflective portion 230 made of a flexible material that reflects sunlight around the heat collecting portion 210 to the heat collecting portion 210 may be provided on a portion of the heat keeping portion 220. In addition, a base film 250 may be provided on the ground, and a reflective part 260 may be provided on a part of the base film 250.
집열부(210)에 수용되는 집열매체로는 물 또는 공기를 이용할 수 있으며, 보온부(220)에 수용되는 보온기체는 공기를 이용할 수 있다.Water or air may be used as the heat collecting medium accommodated in the heat collecting part 210, and air may be used as the heat keeping gas accommodated in the heat keeping part 220.
한편, 본 실시예에서도 보온부(220)를 둘러싸도록 보호막(240a)이 구비된다. 보호막(240a)은 유연재질인 것이 바람직하다. 그런데 본 실시예에서는 보온부(220)와 보호막(240a)이 모든 부분에서 소정거리 이격되도록 한다. 즉, 종래와는 달리, 보온부(220)와 보호막(240a)이 직접 접촉하는 부분이 없다.On the other hand, in the present embodiment, a protective film 240a is provided to surround the heat insulating part 220. The protective film 240a is preferably a flexible material. However, in the present embodiment, the insulating part 220 and the protective film 240a are separated from each other by a predetermined distance. That is, unlike the prior art, there is no part in which the heat insulating part 220 and the protective film 240a are in direct contact.
상세히 설명하면 다음과 같다.The details are as follows.
도 4에서는, 종래의 비고정식 태양열 집열기(도 3의 집열기)에서 다른 조건을 동일하게 하고 보온부(220)와 보호막(240a)이 직접 접촉한 부분만을 소정 거리(L) 이격시킨 것을 도시한 것이다.In FIG. 4, the other non-fixed solar heat collectors (the heat collectors of FIG. 3) have the same conditions, and only a portion where the heat insulating part 220 and the protective film 240a directly contact each other is separated by a predetermined distance (L). .
종래의 비고정식 태양열 집열기에서 보온부(220)와 보호막(240)(도 3의 보호막, 도 4에서는 점선으로 표시)이 형성하는 공간(이하 편의상 '보호공간')은 S1이다. 그런데 본 실시예의 의하면 추가로 S2의 보호공간이 확보된다. 즉, 본 실시예에서의 보호공간은 [S1 + S2]가 된다.In the conventional non-fixed solar heat collector, the space (hereinafter referred to as'protected space' for convenience) formed by the heat insulating part 220 and the protective film 240 (the protective film of FIG. 3 and the dotted line in FIG. 4) is S1. However, according to the present embodiment, a protection space of S2 is additionally secured. That is, the protection space in this embodiment becomes [S1 + S2].
한편, 보온부 내부의 온도(T2), 보호막 내부의 온도(T3), 추가 보호공간의 온도(T3a) 및 외부의 온도(T4)의 관계는, T2 > T3 > T3a > T4 이다. On the other hand, the relationship between the temperature (T2) inside the thermal insulation section, the temperature (T3) inside the protective film, the temperature (T3a) and the outside temperature (T4) of the additional protection space is T2> T3> T3a> T4.
그리고, 본 실시예에서는 보온부(220)의 상부에서 열손실이 추가 보호공간(S2)을 매개로 하여 발생한다. 즉, 추가 보호공간(S2)과 외부 사이에서 열손실이 발생한다. 그런데 추가 보호공간(S2)과 외부의 온도 차이는 (T3a - T4)이다. 이에 반하여, 종래 기술에서는 보온부(220)의 상부와 외부 사이에서 직접 열전달이 발생하고, 둘 사이의 온도 차이는 (T2 - T4)이다. In addition, in the present embodiment, heat loss is generated at the upper portion of the heat insulating part 220 through the additional protection space S2. That is, heat loss occurs between the additional protection space S2 and the outside. However, the difference between the additional protection space S2 and the outside temperature is (T3a-T4). On the other hand, in the prior art, direct heat transfer occurs between the upper part and the outer part of the warming part 220, and the temperature difference between the two is (T2-T4).
그런데, (T3a - T4)가 (T2 - T4)보다 작다. 따라서 본 실시예의 경우에 종래 기술보다 외부로의 열전달에 의한 열손실이 줄어든다.By the way, (T3a-T4) is smaller than (T2-T4). Therefore, in the case of this embodiment, heat loss due to heat transfer to the outside is reduced compared to the prior art.
한편, 보온부(220)와 보호막(240a) 사이의 공간은 일종의 단열공간의 역할을 할 수 있다. 그런데 종래 기술의 경우에는 이러한 공간이 S1인데, 본 실시예에서는 [S1 + S2]가 되어, S2 만큼 커진다. 따라서 이러한 관점에서도 열손실이 줄어든다.Meanwhile, the space between the heat keeping part 220 and the protective film 240a may serve as a kind of heat insulating space. However, in the case of the prior art, this space is S1, but in this embodiment, it becomes [S1 + S2], which is as large as S2. Therefore, even from this point of view, heat loss is reduced.
정리하면, 본 실시예에 의하면, 보온부(220)와 보호막(240a)이 직접 접촉하지 않으므로, 보온부(220)에서 외부로 열전달되어 발생하는 열손실을 최소화할 수 있다. 또한, 보온부(220)와 보호막(240a) 사이의 공간이 충분히 확보되어 보온부(22)에서 외부로 열전달되어 발생하는 열손실을 최소화할 수 있다. In summary, according to the present embodiment, since the heat insulating part 220 and the protective film 240a do not directly contact each other, heat loss caused by heat transfer from the heat insulating part 220 to the outside can be minimized. In addition, a sufficient space between the insulating portion 220 and the protective layer 240a is secured to minimize heat loss caused by heat transfer from the insulating portion 22 to the outside.
한편, 상술한 바와 같이, 보호막(240a)이 모든 부분에서 보온부(220)와 이격되어 설치되는 경우에는, 상기 보호막(240a)을 지지하는 지지부재(300a)가 구비될 수 있다. On the other hand, as described above, when the protective film 240a is installed spaced apart from the insulating part 220 in all parts, a support member 300a for supporting the protective film 240a may be provided.
지지부재(300a)는 직경이 작은 파이프 형태의 부재를 대략 소망하는 곡률로 형성하고, 상기 지지부재(300a)의 외측에 보온막이 설치되는 것이 바람직하다. 지지부재(300a)의 곡률은 보호막(240a)의 곡률에 대응할 수 있다. 예를 들어, 지지부재(300a)의 곡률은 보호막(240a)의 곡률과 동일한 것이 바람직하다.The support member 300a is preferably formed with a pipe having a small diameter at a desired curvature, and a heat insulating film is preferably installed outside the support member 300a. The curvature of the support member 300a may correspond to the curvature of the protective film 240a. For example, the curvature of the support member 300a is preferably the same as the curvature of the protective film 240a.
그리고 지지부재(300a)는 다수개가 앞에서 뒤로 가면서 소정 간격 이격되어 구비되는 것이 바람직하다.In addition, it is preferable that a plurality of support members 300a are spaced apart from each other by going from front to back.
한편, 본 실시예에서는, 보호막(240a)의 형상에 대응하는 지지부재(300a)를 사용하여 보호막(230a)을 설치한다. 따라서, 보호막(230a)의 구배를 자유롭게 할 수 있다. 따라서 보호막(230a)의 붕괴나 우수 등에 의한 오탁을 방지할 수 있도록, 상기 보호막(230a)의 구배를 자유롭게 정할 수 있다.On the other hand, in this embodiment, the protective film 230a is provided using a support member 300a corresponding to the shape of the protective film 240a. Therefore, the gradient of the protective film 230a can be made free. Therefore, the gradient of the protective film 230a can be freely determined so as to prevent contamination of the protective film 230a or contamination due to rainwater.
또한, 본 실시예에서는, 지지부재(300a)를 사용하여 보호막(240a)을 지지한다. 따라서, 보호막(240a)을 견고히 지지할 수 있다.In addition, in this embodiment, the protective film 240a is supported using the support member 300a. Therefore, the protective film 240a can be firmly supported.
도 5를 참조하여, 본 발명에 따른 태양열 집열기의 다른 실시예를 설명한다.5, another embodiment of a solar heat collector according to the present invention will be described.
본 실시예도 상술한 실시예와 작용 원리는 유사하다. 다만, 본 실시예의 보호막(240b)의 형상은 상술한 실시예의 보호막(240a)의 형상과 상이하다.This embodiment is similar in principle to the above-described embodiment. However, the shape of the protective film 240b of this embodiment is different from the shape of the protective film 240a of the above-described embodiment.
상세히 설명하면 다음과 같다.The details are as follows.
본 실시예에서는 보호막과 보온부 사이의 공간을 최대화할 수 있도록 한다. 예를 들어, 동일한 하부의 폭(W) 및 상부 이격거리(L)인 경우에 가능한 최대의 보호공간을 확보하는 것이 바람직하다. 즉, 동일한 하부의 폭(W)을 기준으로 하고, 보온막이 보온부(220)의 상부에서 이격되는 거리(L)가 동일한 경우에, 보호공간이 최대로 되는 것이 바람직하다.In this embodiment, it is possible to maximize the space between the protective film and the warm portion. For example, in the case of the same width (W) and the upper separation distance (L) of the lower portion, it is desirable to secure the maximum possible protection space. That is, it is preferable that the protective space is maximized when the distance L spaced apart from the upper portion of the insulating portion 220 is the same based on the width W of the same lower portion.
이러한 보호막의 형상은 한정되지는 않지만, 보호막(240b)과 지면으로 이루어진 공간의 단면은 대략 사각형 형태로 구성될 수 있다. 이렇게 구성하면, 동일한 하부 폭(W)을 기준으로 할 때, 보호막(240b)과 보온부(220) 사이의 공간을 최대화할 수 있다.The shape of the protective film is not limited, but the cross section of the space formed of the protective film 240b and the ground may be formed in a substantially rectangular shape. When configured in this way, when based on the same lower width (W), it is possible to maximize the space between the protective film 240b and the warm portion 220.
상세히 설명하면 다음과 같다.The details are as follows.
종래기술, 상술한 실시예 및 본 실시예의 비교하여 설명하면 다음과 같다. When comparing the prior art, the above-described embodiment and this embodiment will be described.
종래 기술의 보호공간은 S1이며, 상술한 실시예의 보호공간은 [S1 + S2]이며, 본 실시예의 보호공간은 [S1 + S2 + S3]이다. 따라서 동일한 폭(W)을 기준으로 했을때, 본 실시예의 보호공간이 가장 크게 된다. 따라서, 본 실시예에 의하면, 보온부(220)의 상부에서의 열손실뿐만 아니라, 보온부(220)의 측면(대략 대각선 방향)에서의 열손실도 최소화할 수 있다.The protection space of the prior art is S1, the protection space of the above-described embodiment is [S1 + S2], and the protection space of the present embodiment is [S1 + S2 + S3]. Therefore, when it is based on the same width (W), the protection space of the present embodiment is the largest. Therefore, according to the present embodiment, it is possible to minimize not only the heat loss at the upper portion of the heat insulating portion 220, but also the heat loss at the side (approximately diagonal direction) of the heat insulating portion 220.
한편, 본 실시에에서도 보호막(240b)를 지지하는 지지부재(300b)가 구비되는 것이 바람직하다. 지지부재(300b)는 수직부재(310)와 수평부재(320)를 포함할 수 있다. 수직부재(310)는 보온부(220)에서 소정 거리 이격된 지점의 바닥에서 상부로 연장된다. 수직부재(310)는 최소한 보온부(220)의 직경보다는 길게 상부로 연장되는 것이 바람직하다. 수평부재(320)는 좌우의 수직부재(310)의 상부를 연결하는 부재이다.Meanwhile, in the present embodiment, it is preferable that a supporting member 300b for supporting the protective film 240b is provided. The support member 300b may include a vertical member 310 and a horizontal member 320. The vertical member 310 extends from the bottom of the point spaced a predetermined distance from the warming part 220 to the top. It is preferable that the vertical member 310 extends upwardly at least longer than the diameter of the heat keeping part 220. The horizontal member 320 is a member connecting the upper left and right vertical members 310.
한편, 본 실시예에서는, 보호막(240b)과 지면으로 이루어진 공간의 단면이 대략 사각형인 것을 도시 및 설명하였지만 본 발명은 이에 한정되지 않는다. 예들 들어, 보호막(240b)과 지면으로 이루어진 공간의 단면이 대략 오각형 형태로 구성될 수도 있다. 이렇게 하면, 보호막(240b)과 보온부(220) 사이의 공간을 최대화하면서 동시에 보호막(240b) 상부에 구배를 줄 수 있다. 이러한 경우에는, 수직부재(310)와 수평부재(320)를 바로 연결하지 않고, 수직부재(310)의 선단과 수평부재(320)의 일단의 사이에 대략 경사진 경사부재(315)를 추가로 구비하는 것이 바람직하다. 경사부재는 곡선형태로 구성할 수도 있다.On the other hand, in this embodiment, the cross-section of the space formed of the protective film 240b and the ground is illustrated and described, but the present invention is not limited thereto. For example, the cross section of the space formed of the protective layer 240b and the ground may be configured in a substantially pentagonal shape. In this way, it is possible to maximize the space between the protective film 240b and the warming part 220 and at the same time give a gradient over the protective film 240b. In this case, the vertical member 310 and the horizontal member 320 are not directly connected, and an inclined member 315 that is approximately inclined between the tip of the vertical member 310 and one end of the horizontal member 320 is additionally added. It is preferably provided. The inclined member may be configured in a curved shape.
또한, 보호막(240b)의 수평부재(320)를 반구형, 삼각형 등으로 구성하여, 보호막(240b)의 상부에 구배를 줄 수도 있다. 또한, 수직부재(310)가 내측으로 약간 경사를 가지게 구성할 수도 있다.In addition, the horizontal member 320 of the protective film 240b may be configured as a hemispherical shape, a triangle, or the like, to give a gradient to the upper portion of the protective film 240b. In addition, the vertical member 310 may be configured to have a slight inclination inward.
이렇게 구성하면, 보호막(240b) 상부의 구배에 의하여, 보호막(240b)의 상부 외면에 쌓일 수 있는 눈, 비, 먼지 등이 보호막의 상부 외면에 쌓이지 않고 아래로 잘 쓸려 내려가게 할 수 있다. 따라서, 태양광이 보호막을 잘 통과하여 집열 성능이 향상된다.When configured in this way, by the gradient of the upper portion of the protective layer 240b, snow, rain, dust, etc., which may accumulate on the upper outer surface of the protective layer 240b, may not be accumulated on the upper outer surface of the protective layer and may be swept down well. Therefore, the sunlight passes through the protective film well, and the heat collection performance is improved.

이상에서 설명한 바와 같은 태양열 집열기는 보온부와 보호막이 직접 접촉하지 않는다. 따라서 보온부에서 외부로 열전달되어 발생하는 열손실을 최소화할 수 있다. 또한, 보온부와 보호막 사이의 공간 즉 일종의 단열공간이 충분히 확보되어, 보온부에서 외부로 열전달되어 발생하는 열손실을 최소화할 수 있다. 또한, 지지부재를 이용하여 보호막을 지지하므로, 보호막의 구배를 자유롭게 할 수 있고 보호막을 견고하게 지지할 수 있다.As described above, the solar heat collector does not directly contact the warming portion and the protective film. Therefore, it is possible to minimize heat loss caused by heat transfer from the heat insulating part to the outside. In addition, a space between the heat insulating part and the protective film, that is, a kind of insulating space is sufficiently secured, and heat loss caused by heat transfer from the heat insulating part to the outside can be minimized. In addition, since the protective film is supported by the support member, the gradient of the protective film can be freed and the protective film can be firmly supported.
