た、特に中温集熱コレクターに適する太陽集熱器
に関する。[Detailed explanation of the invention] This invention consists of a mirror, a heat collector that receives solar radiation from the mirror, and a heat pipe that absorbs the heat of the heat collector in a translucent outer tube. The present invention relates to a solar collector that is particularly suitable for a medium-temperature collector, in which the support means for the heat collector is improved so as not to impair the selective absorption ability of the heat collector.
従来太陽集熱器としては、比較的低温（30〜95
℃）の集熱を行ない給湯・冷暖房などに用いるも
のが多用されてきた。しかし化石エネルギー事情
が逼迫してくるにつれて、産業用として中温
（100〜250℃）の集熱が要望されるようになり、
中温の集熱を効率よく行うコレクターが出現して
きている。中温集熱コレクターは集熱媒体の温度
が100〜250℃となり、媒体としては通常、水を用
い高圧熱水もしくは高圧蒸気として供用されてい
る。 Conventional solar collectors have relatively low temperatures (30 to 95
℃), and have been widely used for hot water supply, air conditioning, and heating. However, as the fossil energy situation becomes tighter, medium-temperature (100-250℃) heat collection is required for industrial use.
Collectors that efficiently collect medium-temperature heat are emerging. In medium-temperature heat collectors, the temperature of the heat collecting medium is 100 to 250°C, and the medium is usually water, which is used as high-pressure hot water or high-pressure steam.
ところで中温集熱板表面に形成させる選択吸収
膜の性能は、低温用と比較して、α（吸収率）は
ほぼ同じでもε（放射率）を特に留意して低くし
なければ集熱板からの再放射が多くなるため集熱
効率が低下する。 By the way, the performance of the selective absorption film formed on the surface of the medium-temperature heat collecting plate is that compared to the low-temperature film, α (absorption rate) is almost the same, but unless special attention is paid to lowering ε (emissivity), the performance of the selective absorption film will be lower than that of the heat collecting plate. Heat collection efficiency decreases due to increased re-radiation.

固定されている。 Figures 1, 2, 3, 4a, and 4b show an external perspective view, an exploded perspective view, and a longitudinal cross-sectional view of an example of a solar collector that is currently widely used for medium-temperature heat collection. That is, a mirror 2 is housed inside a light-transmitting outer tube 1, a heat collecting section consisting of a heat collector 3 and a heat pipe 5 is disposed within its focal point, and air in a space 4 inside the light-transmitting outer tube is exhausted. This is a solar collector that has been vacuumed to give it an insulating effect. The heat receiving end 6 of the heat pipe 5 is disposed in the heat collecting section, and the heat medium pipe 8 communicating with the load section is disposed coaxially within the cylindrical heat supplying end 7 for heat exchange. . The outer wall of the heat pipe constituting the heat receiving end 6 is provided with a heat collector 3 having a height sufficient for the mirror 2 to track the solar displacement and cover the displacement of the focal point.
are thermally connected, and a selective absorption film of nickel oxide, chromium oxide, etc. is applied to the surface. The heat collector 3 also includes support columns 9a, 9b whose lower ends 12a, 12b are fixed to the upper part of the heat collector 3 using metal wire rods having spring properties, and an arcuate support ring 11a fixed to the upper ends 10a, 10b of the support columns 9a, 9b. , 11b and a footing 1 whose one end 12'a, 12'b is fixed to the lower part of the heat collector 3 and extended to the inner wall of the transparent outer tube 1.
3a and 13b, the mirror 2 is fixed at an appropriate position.

るのでその結果集熱効率を著しく低下させる。 The support columns 9a, 9b and the heat collector 3 and the footings 11 and the heat collector 3 are often secured to each other by brazing with phosphor-copper brazing, silver brazing, or the like. Generally, a selective absorption film of nickel oxide, chromium oxide, or the like is formed on the surface of the heat collector 3 by electroplating, which is inexpensive. When such a heat collector is fixed by brazing as described above, it is difficult to form a good film around the fixed portion. That is, this is because plating spots occur due to differences in the surface condition of the surface to be plated. Particularly when the purpose is medium-temperature heat collection, the plating spots around the fixed portions significantly reduce the selective absorption ability of the heat collector 3, resulting in a significant reduction in heat collection efficiency.

ある。 This invention is an improvement on the above-mentioned fixing means in order to solve the above-mentioned problems, and consists of a mirror, a heat collector that is irradiated with concentrated sunlight by the mirror, and a heat sink that absorbs the heat of the heat collector. A solar heat collector in which a pipe is installed inside a translucent outer tube, the top part of which is bent in a dogleg shape, extended downward in a downwardly expanding shape, and both lower ends bent in a dogleg shape. It is equipped with a support column made of solid spring wire, and a support ring having an arc shape and having its top fixed to the top of the support column.Furthermore, two holes are provided in the heat collector so that both sides of the support column can be connected to each other. The present invention provides a solar collector characterized in that the heat collector is held by engaging the character-shaped portion with the edge of the perforation.

Therefore, the heat collector of this invention is particularly excellent for medium temperature heat collection.

い。 A perspective view and a cross-sectional view of the main parts of an embodiment of the solar collector of this invention are shown in Figs. 5a and 5b. A support column 23 made of a spring wire whose top portion 21 is bent into a U-shape and extends downwardly and whose lower ends 22a and 22b are bent into a U-shape, and a support ring 25 which is arc-shaped. the top 24 of the support column and the top 2 of the support column
1 are fixed perpendicularly to each other. Furthermore, heat collector 2
Two perforations 27a and 27b are provided in the support column 2.
Both U-shaped portions 22a and 22b of No. 3 are engaged with the perforation edge. In this way, the support column 23 and the heat collector 2
6 are physically engaged without using metal solder, so a good and uniform selective absorption film can be formed on the surface of the heat collector 26. Therefore, high heat collection efficiency can be obtained especially in medium temperature heat collection. Further, the support column and the support ring do not necessarily have to be fixed perpendicularly to each other, as long as the support column and the heat collector are fixed in a manner as shown in FIG. 5a. Further, in the above embodiment, the footing 28 is connected to the heat collector 26.
One end 29 thereof is soldered and fixed to the lower part of the holder.
The lower part of the heat collector 26 does not make a large contribution to the heat collection efficiency, so even if it is brazed, it will not have a large effect on the heat collection efficiency, but it is the same as the method of fixing the support column 23 and the heat collector 26 described above. Preferably, it is fixed by a method.
