本考案は集熱板を封入した真空透光管からなる集熱素子
と反射板とを組合せた集光式太陽集熱器の改良構造に関
する。[Detailed Description of the Invention] The present invention relates to an improved structure of a concentrating solar collector that combines a heat collecting element made of a vacuum transparent tube enclosing a heat collecting plate and a reflecting plate.
斯る集光式として第1図々示の如く放物面1aと円弧面
1bとを連続形成した反射素体1の該放物面1aの焦点
即ち円弧面の中心でもあるA点から円弧面1bの外端縁
Bに互って集熱板2を位置させ、反射素体1から反射さ
れた太陽光を集熱部材2の裏面(反射板に対向する側)
で受けるようになっている。As such a condensing type, as shown in Fig. 1, a reflective element 1 has a paraboloid 1a and a circular arc surface 1b formed in succession, and from point A, which is the focal point of the paraboloid 1a, that is, the center of the circular arc surface, to the circular arc surface. The heat collecting plates 2 are placed on the outer edges B of 1b, and the sunlight reflected from the reflective element 1 is collected on the back side of the heat collecting member 2 (the side facing the reflecting plate).
It is now accepted at
斯る集光式の集熱板2はすべて裏面で太陽光を受けるよ
う設計され、表面側は放熱しないよう断熱処理されてい
る。All such light-concentrating heat collecting plates 2 are designed to receive sunlight on the back side, and are heat-insulated on the front side so as not to radiate heat.
これは表面側でも太陽光を受けることができるが受熱よ
り放熱の方が大きいため斯る処理を行っているのである
。This treatment is done because although the surface side can receive sunlight, the heat radiation is greater than the heat reception.
一方集光率を向上させるためには放物面1a部分の開口
幅(A点から放物面1aの外端縁Cまでの距離)を大き
くした方がよい。On the other hand, in order to improve the light collection efficiency, it is better to increase the aperture width of the paraboloid 1a (the distance from point A to the outer edge C of the paraboloid 1a).
そのため外端縁Cは集熱部材2よりも上方に位置するこ
とになりその上限は冬至の太陽Sからの入射限度である
。Therefore, the outer edge C is located above the heat collecting member 2, and its upper limit is the limit of incidence from the sun S at the winter solstice.
しかし乍ら斯る反射素体単体を複数個用いて必要とする
集熱量を得ようとした場合、第2図々示の如く隣合う集
熱部材2間の距離がL寸法必要となり又夫々の反射素体
単体が独立しているためその取付けが煩雑であった。However, when attempting to obtain the required amount of heat collection by using a plurality of such single reflective elements, the distance between adjacent heat collection members 2 must be L dimension as shown in Figure 2, and each Since the reflective element is independent, its installation is complicated.
本考案は斯る点に鑑みなされたもので放物面の外端縁を
下げて放物面の開口幅を多少減少させるがこの減少分を
熱損失の少ない真空管式集熱素子を用いることにより補
うと共に反射板を一体形成することによりコストダウン
と設置作業性を向上し、しかも集熱素子間の距離を短か
くし限られた設置場所に、より多くの集熱素子を配置し
集熱量を増加させるようにしたものである。The present invention was devised in view of this point, and the outer edge of the paraboloid is lowered to reduce the opening width of the paraboloid to some extent, but this reduction is compensated for by using a vacuum tube type heat collecting element with less heat loss. In addition, by integrally forming the reflector plate, costs are reduced and installation workability is improved, and the distance between heat collecting elements is shortened to increase the amount of heat collected by placing more heat collecting elements in a limited installation space. It was designed to let you do so.
以下第3図と第4図について一実施例を説明すると、ス
テンレス等の金属板或いは合成樹脂板に反射面を構成し
た板射板Mは、放物面1aと円弧面1bからなる複数個

る反射素体1の円弧面1bの外端縁Bとを連続すると共
に該面外端縁の高さを略同−にして前記材料にて一体形
成しである。An example will be described below with reference to FIGS. 3 and 4. A radiation plate M having a reflective surface formed of a metal plate such as stainless steel or a synthetic resin plate has a plurality of parabolic surfaces 1a and arcuate surfaces 1b. It consists of a reflective element 1, and the outer edge C of the paraboloid 1a is continuous with the outer edge B of the circular arc surface 1b of the adjacent reflective element 1, and the heights of the outer edges of the surface are approximately the same. It is integrally formed with the above-mentioned material.
前記各反射素体1,1・・・・・・の円弧面1b上には
該円弧面より間隔をあけて配置した真空管式集熱素子H
は第5図々示の如くガラスの真空外管3内に水等の熱媒
体を通す銅パイプりが装設され、更に銅パイプ4には銅
、アルミ等の翼状集熱板2が取付けられて構成されてい
る。Vacuum tube type heat collecting elements H are arranged on the arcuate surfaces 1b of each of the reflective elements 1, 1, . . . at intervals from the arcuate surfaces.
As shown in Fig. 5, a copper pipe for passing a heat medium such as water is installed in a glass vacuum outer tube 3, and a wing-shaped heat collecting plate 2 made of copper, aluminum, etc. is attached to the copper pipe 4. It is composed of
そしてこの集熱素子H,H・・・・・・は各反射素体1
上に配置するに当って集熱板2が放物面1aと円弧面1
bの夫々の外端縁B、C間を結ぷ゛線状に略一致するよ
う水平に置かれ且その集熱板2の一端が放物面1aの焦
点A部分に略位置するようになされる。The heat collecting elements H, H... are each reflective element 1.
When placing the heat collecting plate 2 on the top, the heat collecting plate 2 has a parabolic surface 1a and a circular arc surface 1.
The heat collecting plate 2 is placed horizontally so that the outer edges B and C of the heat collecting plate 2 are substantially aligned in a line connecting each other, and one end of the heat collecting plate 2 is substantially located at the focal point A of the paraboloid 1a. Ru.
第6図は水平より角度θだけ傾斜した線上に反射板Mの
底面がくるよう反射素体1,1・・・・・・を組合せた
もので、この場合は放物面1aが直角三角形の斜辺に相
当するので第3図に示したものよりも放物面1aの開口
幅を大きくすることが可能である。Figure 6 shows a combination of reflective elements 1, 1, etc. so that the bottom surface of the reflector M is on a line inclined at an angle θ from the horizontal, and in this case, the paraboloid 1a is a right triangular shape. Since this corresponds to the oblique side, it is possible to make the aperture width of the paraboloid 1a larger than that shown in FIG.
この反射板を使用する時は集熱素子Hの集熱板2を水平
に設置する。When using this reflector, the heat collecting plate 2 of the heat collecting element H is installed horizontally.
而して太陽光は直接集熱板2の表面に照射されると共に
夫々の反射素体1からの反射光が集熱板の裏面に照射さ
れるので集熱パイプ4内の熱媒体が加熱される。The sunlight is directly irradiated onto the surface of the heat collecting plate 2, and the reflected light from each reflective element 1 is irradiated onto the back surface of the heat collecting plate, so that the heat medium in the heat collecting pipe 4 is heated. Ru.
真空管式集熱素子は真空層が断熱機能を発揮するので集
熱板の表面からの放熱はないのは勿論のこと直射光をも
集熱に利用できる等有益な効果を奏する。Since the vacuum layer of the vacuum tube type heat collecting element exhibits a heat insulating function, there is no heat radiation from the surface of the heat collecting plate, and even direct light can be used for heat collection, which has beneficial effects.
又放物面の外端縁と隣接する反射素体の円弧面の外端縁
を連続すると共に面外端縁の高さを略同−にして一体的
に反射板を構成したので多少放物面の開口幅が狭くなる
が第2図点線で示す如く集熱素子間の間隔lが小さくな
り限られた設置場所に多くの集熱素子を配置できる。Also, since the outer edge of the paraboloid and the outer edge of the adjacent arcuate surface of the reflecting element are continuous and the heights of the outer edge of the surface are approximately the same, the reflector is constructed integrally, so it is somewhat parabolic. Although the opening width of the surface becomes narrower, the interval l between the heat collecting elements becomes smaller as shown by the dotted line in Figure 2, and many heat collecting elements can be arranged in a limited installation space.
しかも真空管式集熱素子を用い、反射光の他に直射光に
よっても集熱させるようにしたので放物面の開口幅の減
少をカバーで゛きる。Moreover, since a vacuum tube type heat collecting element is used to collect heat not only by reflected light but also by direct light, the reduction in the opening width of the paraboloid can be compensated for.
