【発明の詳細な説明】
本発明は太陽熱集熱器に関する。更に詳しくは従来の反
射ミラーを備えた集光式集熱器より優れた集熱効果を示
す太陽熱集熱器に関する。DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a solar collector. More specifically, the present invention relates to a solar heat collector that exhibits a better heat collecting effect than a conventional concentrating type heat collector equipped with a reflective mirror.
一般家庭において使用する温水はおもに給湯用のため１
００℃以下でよいためあまり集熱効率を問題にしなかっ
た。Hot water used in general households is mainly for hot water supply, so 1.
Since the temperature could be below 00°C, heat collection efficiency was not much of an issue.
しかし乍ら産業界においては１００℃以下の集熱の用途
は少なく、逆に１００〜２００℃の集熱の用途は多く全
熱エネルギーの約３０憾をもカが−するといわれている
。However, in the industrial world, there are few uses for collecting heat at temperatures below 100°C, and on the contrary, there are many uses for collecting heat at 100 to 200°C, which are said to consume about 30% of the total thermal energy.

もコスト高となるため実験的にしか採用されておらず実
用化されていないのが現状である。As a means for performing such high-humidity heat collection, a heat collector may be constantly tracked toward the axis of sunlight in accordance with the displacement of solar incidence. However, such tracking means requires a tracking function that moves mirrors, lenses, or heat collecting plates, energy for that purpose, and a structure to support it, so the cost is higher than the amount of energy that can be obtained, so it can only be done experimentally. At present, it has not been adopted and put into practical use.
本発明は希薄な太陽熱エネルギーを非追尾でミラーでも

かなり長くなるためその差が集熱に寄与しない部分とな
ってしまい不利である。The present invention attempts to condense dilute solar thermal energy using a mirror without tracking it, heat a heat collecting member to a high temperature, and extract thermal energy of 100 to 200°C. Conventionally, two means have been devised as such a heat collector. One of them, as shown in the cross section in Figure 1, has a height sufficient to cover the displacement of the focal point that tracks the solar displacement of the curved reflecting mirror (1), that is, a large outer diameter (IIφ). Heat collection pipe (
2) is used. In this way, the maximum angle of incidence θ
Incident light rays at an angle smaller than 2 are collected by the heat collection pipe (2)≦=, making it possible to collect heat from the lagoon. Note that a indicates the normal line at point A of the mirror (1). However, the working fluid that changes into two phases, gas and liquid, sealed in this thick heat collecting pipe (2) must be filled into the device according to the internal volume of the heat collecting pipe, and when the working fluid is depleted, In order to withstand this pressure, a sufficiently thick walled pipe with pressure resistance is required, which increases costs. Table III length of pipe cross section is required surface length 1)
Since it is quite long, the difference becomes a part that does not contribute to heat collection, which is disadvantageous.

。The second conventional structure has a height H as shown in Figures 2 and 3.
(same meaning as H in Figure 1) is arranged on the axis of symmetry Q) of the cross section of the curved reflecting mirror t1), and is fitted onto a part of this heat collecting plate (3). A matching groove is provided, and a heat collecting pipe (2) of an optimal thickness is attached to this matching groove for heat conduction.
斯る構造のものは集熱ｈ（３）と集熱パイプ（２）とを
Ｉえた横断面の表面長が・仏姿表面長Ｃ橋めて近いので
放熱に−く部分（無効部分）が少なくてすむ長所がある
。しかし乍ら次に記述するような欠点がある。In such a structure, the surface length of the cross section including the heat collection h (3) and the heat collection pipe (2) is very close to the Buddha figure surface length C, so there is a part that is difficult to dissipate (ineffective part). It has the advantage of requiring less. However, there are drawbacks as described below.

対称軸Ｑ上に一致させることは螢暖で、且熱伸縮して第
３図のように波状に髪形する。b) The material of the heat collecting plate (3) is often made of copper, aluminum, or their alloys, which have good thermal conductivity, but these are soft and difficult to maintain linearity, so when assembling the plate, it is necessary to Coincident with the axis of symmetry Q is hot and thermally expands and contracts, resulting in a wavy hairstyle as shown in Figure 3.

がし難い。i) When applying compensation absorbing fusuma to the surface of the heat collecting pipe 1iif3) and the heat collecting pipe 12), it is necessary to polish the surface to create a textured surface in order to improve its performance, but the surface shape is complicated. Therefore, it is difficult to polish the intersection A part between the pipe and the heat collecting plate.

However, with this method, the metal layer becomes thicker, the specular state of the surface deteriorates, the surface roughness increases, the surface area increases, and heat dissipation becomes easier, and the selective absorption ability deteriorates.

上げができ、従ってこの上に１択吸収膜を付与した場合
の選択吸収能が向上する。The present invention eliminates the two drawbacks of the conventional structure,
A vertically hollow heat collecting cover with a selective absorbing film formed on the outer surface is provided so as to include the symmetry axis of the cross section of the concave reflecting mirror, and a heat collecting pipe is inserted into the heat collecting cover. The present invention provides a solar heat collector in which a heat collecting cover and a heat collecting cover are brought into contact with each other in a heat conductive manner. By having such a structure, 4. Since the outer surface is simple, it can be easily polished and mirror-finished, and therefore, the selective absorption ability is improved when a selective absorption film is provided thereon.
向 パイプとカバーとの鑞付けはカが−内面で行なえる
ので外表面に虐択吸１ｔＹ幌を付与才る際の障害になら
ない。Since the brazing between the pipe and the cover can be done on the inner surface, it will not be an obstacle when attaching the 1tY canopy to the outer surface.
Ｃ） カバーは中空状になっているため一枚の集熱板の
ように直線性を禮持するのは難しくない。C) Since the cover is hollow, it is not difficult to maintain linearity like a single heat collecting plate.
の 最適太さの集熱パイプが使用できるので収納する作
動液の置も少なくてすむので高温作動時の内圧もそれ程
上昇しないので肉薄のパイプでよい。Since a heat collecting pipe of the optimum thickness can be used, there is less storage space for the working fluid, and the internal pressure does not increase significantly during high temperature operation, so a thin walled pipe can be used.
の 中空状のカバーであるのでカバー内面から放熱して
も対向するカバー内面に吸収し外方へは放散しないので
放熱は極めて少ない。Because the cover is hollow, even if heat is radiated from the inner surface of the cover, it is absorbed by the opposing inner surface of the cover and is not radiated outward, so the amount of heat radiated is extremely small.
