【考案の詳細な説明】
本考案は、水などの熱媒体を熱媒管に通し、こ
の熱媒管に連結されている集熱板で受けた太陽熱
により熱を得る真空管式太陽熱集熱器に関する。[Detailed description of the invention] The present invention relates to a vacuum tube type solar collector that passes a heat medium such as water through a heat medium tube and obtains heat from the sun's heat received by a heat collecting plate connected to the heat medium tube. .
一般に、この種の太陽熱集熱器において、透明
ガラス外管と熱媒管との熱膨張の差による機械的
強度の観点から、熱媒の入口と出口を同一側にし
た往復路方式が好ましい。そして、集熱効率を高

いほど有利である。したがつて、通常第１図に示
すように集熱板の下方に、往復路の熱媒管３，４
を電気溶接やハンダなどで両方の熱媒管とも集熱
板と連結している。 Generally, in this type of solar heat collector, from the viewpoint of mechanical strength due to the difference in thermal expansion between the transparent glass outer tube and the heat medium tube, a reciprocating system in which the heat medium inlet and outlet are on the same side is preferable. In order to improve heat collection efficiency, it is advantageous to have a larger contact area between the heat collection plate and the heat medium tube. Therefore, as shown in FIG.
Both heat medium pipes are connected to the heat collector plate by electric welding or soldering.
ところが、真空ガラス管式集熱器は、通常集熱
板の幅が50〜90mmであり、このように比較的小さ
い場合には第２図に示すように熱媒管は１本のみ
連結されている場合でも、集熱効率が大幅に低下
することがないことや、比較的厚さの薄い集熱板
に２本の管に平行に連結するのが技術的に難しい
ので量産性が乏しく、また集熱板が歪曲すること
がある。 However, in vacuum glass tube type heat collectors, the width of the heat collecting plate is usually 50 to 90 mm, and in such a relatively small case, only one heat medium tube is connected as shown in Figure 2. Even if the heat collection efficiency is not significantly reduced, and it is technically difficult to connect two pipes in parallel to a relatively thin heat collection plate, mass production is poor, and the heat collection efficiency is low. The hot plate may become distorted.
そこで、加工が容易で、その結果経済的にもす
ぐれた第２図に示す構成が提案されている。この

に２本の熱媒管を対称に封口することが機械的強
度の点で好ましいので、２本の熱媒管３′，４′と
も、封口部では曲げることが必要となり余分の工
数を要する欠点があつた。 Therefore, the structure shown in FIG. 2 has been proposed, which is easy to process and, as a result, is economical. This type is excellent in the above points, but the heat collecting plate 2'
It is unstable because it is supported by a single heat transfer pipe. In addition, at the sealing part between the heat medium tube and the glass outer tube 1',
As shown in FIG. 3, it is preferable to seal the two heat medium tubes symmetrically around the center point of the glass tube 1' from the viewpoint of mechanical strength. In both cases, the sealing part had to be bent, which required extra man-hours.
本考案は上記従来の欠点を解決するものであ

い。 The present invention solves the above-mentioned conventional drawbacks, and one embodiment of the present invention will be described below with reference to the drawings. FIG. 4 is a block diagram of an embodiment of the present invention. Similar to FIG. 1, the heat collecting plate 7 is supported by the two heat medium pipes 5 and 6, but the difference is that only one of the heat medium pipes 5 and 6, whose tips are connected in a U-shape, is supported by the heat collecting plate 7. The two are welded together, and the other is simply placed on top.
There is no particular connection. The heat collecting plate 7 and heat medium pipes 5 and 6 are sealed in a glass tube 8 under reduced pressure.
This structure is economically advantageous and can provide a heat collector that is easy to manufacture.
In this configuration, it is preferable to make the one of the U-shaped heat medium pipes connected by capacitance or the like to be on the heat medium outlet side in order to raise the heat collection temperature as much as possible.

ラス外管内に固定するために、これらの支持金具
を用いている。 Although not shown in Figs. 1, 2, 3 and 4, these support fittings are used to fix the heat collecting plate and the heat medium tube inside the outer glass tube.

提案することができる。 As described above, according to the present invention, the heat medium tube can be drawn out to the center of the glass tube without bending the heat medium tube, so it is easy to assemble and the vacuum glass tube has strong mechanical strength. We can propose a type solar heat collector.
