本考案は太陽熱温水器の吸熱部に適した太陽熱
集熱器に関するものである。[Detailed Description of the Invention] The present invention relates to a solar heat collector suitable for the heat absorption part of a solar water heater.
従来、此種の太陽熱集熱器として第１図に示す

熱フイン１の垂直片１′にバーリング穴２を設け

ング穴２に密着させるようにしてある。 Conventionally, the one shown in FIG. 1 has been proposed as this type of solar heat collector. In the figure, a large number of L-shaped aluminum heat collecting fins 1 are arranged side by side, a burring hole 2 is provided in the vertical piece 1' of each heat collecting fin 1, and a heat collecting pipe 3 is inserted through it. The tube is expanded to fit tightly into the burring hole 2.
この場合、集熱フイン１はアルミニウム製で熱

このため、塗装むらが生じ、薄く均一に仕上げる
ことが困難となり、所要な選択吸収特性が得られ
ないという欠点があつた。 In this case, the heat collecting fin 1 is made of aluminum and has high thermal conductivity, and since the heat collecting tube 3 is in close contact with the burring hole 2 due to tube expansion, sufficient heat conductivity can be obtained with a thin plate, and the specific gravity is small, so it is lightweight. It has the advantage of being able to However, in order to make one heat collecting plate, a large number of heat collecting fins 1 must be joined, and this assembly is troublesome. Furthermore, when using a thin plate, the tip is sharp and the mechanical strength is weak, making it dangerous to handle and easily damaged. Furthermore, in order to absorb solar heat well, a selectively absorbent paint is applied to the outer surface of the heat collecting fin 1, but it is troublesome to apply it to each fin one by one before assembly, so spray painting is performed after assembly. It is.
As a result, coating unevenness occurs, making it difficult to achieve a thin and uniform finish, and the desired selective absorption characteristics cannot be obtained.
本考案は上述した従来の欠点を解消せんと図ら

することを目的とする。 This invention was designed to solve the above-mentioned conventional drawbacks, and it strengthens the bond between the heat collecting plate and the heat collecting tube to improve thermal conductivity, and uses a thin heat collecting plate. The aim is to make the heat collecting plate easier to assemble and mass produce, while also making it easier to assemble the heat collecting plate, reducing the number of sharp parts and making it easier to handle. The purpose is to facilitate formation.

This is due to the fact that it is in close contact with the

バーリング穴５に密着して組立てが終了する。 As shown in FIG. 3, such a solar heat collector uses a thin metal plate (thickness 0.4 mm) such as aluminum as the heat collecting plate 4, and at this stage, selective absorption is applied to the surface of the heat collecting plate 4. Apply a thin layer of paint evenly. Thereafter, as shown in FIG. 4, burring holes 5 and burring holes 6 are alternately drilled at predetermined intervals, and these are provided in rows corresponding to the number of heat collecting pipes 7 to be used, and the broken line portions are bent. By processing, a vertical portion 4a and an inclined portion 4b are continuously formed on the heat collecting plate 4. Then, heat collecting tubes 7 are inserted alternately into the burring holes 5 and burring holes 6 in each row of the heat collecting plate 4, and by applying hydraulic pressure or the like to the heat collecting tubes 7 and expanding them, the heat collecting tubes 7 are inserted into the burring holes 5. Once they are in close contact, assembly is complete.
本考案は上述の如く構成されているので次のよ
うな作用効果を有する。 Since the present invention is constructed as described above, it has the following effects.
集熱管７は集熱板４のバーリング穴５に密着
されるので、集熱板４にて集熱された太陽熱が
集熱管７に良好に伝達され、太陽熱を有効利用
できる。 Since the heat collecting pipe 7 is closely attached to the burring hole 5 of the heat collecting plate 4, the solar heat collected by the heat collecting plate 4 is well transmitted to the heat collecting pipe 7, and the solar heat can be effectively utilized.
集熱板４は剛性のあるＮ形を有し、集熱管７

容易である。 The heat collecting plate 4 has a rigid N shape, and the heat collecting pipe 7
It is strong because it is integrated, and the tip is bent and has few sharp parts, making it easy to handle.
熱伝導性が良く、強度を持たせてあるので、
極力、集熱板４を薄くでき、軽量化が図れる。 It has good thermal conductivity and is strong, so
The heat collecting plate 4 can be made as thin as possible and its weight can be reduced.

斜部４ｂの穴は寸法精度の粗いバカ穴６にして
いるので、集熱板４自体の製作が容易であると
共にこれと集熱管７との組立ても簡単であり、
集熱器の工場での大量生産に適している。 A heat collecting plate 4 having a meandering vertical part 4a and an inclined part 4b can be manufactured by continuous machining of a single metal plate, and the hole in the inclined part 4b through which the heat collecting pipe 7 is inserted has a rough dimensional accuracy. Since the hollow holes 6 are formed, it is easy to manufacture the heat collecting plate 4 itself, and it is also easy to assemble it with the heat collecting pipe 7.
Suitable for mass production in heat collector factories.
加工前に集熱板４の表面に予め選択吸収面を
形成することが可能であり、所要な選択吸収特

温水器１０に適用すれば、反射板９からの反射
光も適確に捕えることができる。 Since the heat collecting plate 4 is N-type, a large amount of heat can be collected regardless of the height of solar radiation as shown in FIG. Therefore, if the heat collector is applied to a solar water heater 10 having a reflecting plate 9 in the hot water tank 8 as shown in FIG. 6, the reflected light from the reflecting plate 9 can also be accurately captured.
