【考案の詳細な説明】
この考案は、平板状フィンの湾曲溝部に通水管が強制圧
入されて戊る、いわゆるかち込み型のフィン付き管にお
けるフィンの移動防止装置に関する。[Detailed Description of the Invention] This invention relates to a device for preventing movement of fins in a so-called wedge-type finned tube in which a water passage pipe is forcibly press-fitted into a curved groove of a flat fin.
一般にこの種のフィン付き管は、給水ヘッドと排水ヘッ
ドの間に並列状に多数配設されて、太陽熱集熱器として
使用される。Generally, a large number of finned tubes of this kind are arranged in parallel between a water supply head and a drainage head and used as a solar heat collector.
ところで、集熱器の使用中にフィンが通水管上を移動す
る場合がある。By the way, the fins may move on the water pipes during use of the heat collector.
このような製品では、ヘッダとフィン付き管との接続部
のろう付けが破損することがあるため、フィンの移動防
止手段が要望せられている。In such products, the brazing of the connection between the header and the finned tube may be damaged, so there is a need for means for preventing movement of the fins.
この考案は上記要望にこたえるべくなされたものであっ
て、フィン付き管におけるフィン移動防止装置を提供す
るものである。This invention was made in response to the above-mentioned need, and provides a device for preventing fin movement in a finned tube.
以下、この考案を図示実施例により具体的に説明する。This invention will be specifically explained below with reference to illustrated examples.
第１図、第２図において、１はアルミニウム押出型材の
フィンであって、幅の中間部に半円形の嵌合溝部２を有
する。In FIGS. 1 and 2, reference numeral 1 denotes a fin made of extruded aluminum, and has a semicircular fitting groove 2 in the middle part of its width.
３は嵌合溝部２に強制圧入された銅製の通水管であって
、嵌合溝部２のスプリングバック作用によって溝内に密
着状態で保持されている。Reference numeral 3 denotes a water pipe made of copper that is forcibly press-fitted into the fitting groove 2, and is held in close contact within the groove by the springback action of the fitting groove 2.
そして通水管３はフィン装着位置からやや端部側にてク
ランク状に屈曲されている。The water pipe 3 is bent into a crank shape slightly toward the end from the fin mounting position.
この屈曲部３ａにてフィン１が移動を阻止せられる。The fin 1 is prevented from moving at this bent portion 3a.
第３図、第４図、第５図はこの考案の変形例を示すもの
である。FIGS. 3, 4, and 5 show variations of this invention.
これらの例では通水管３は直管状のままであって、その
フィン装置位置からやや端部側にストッパ４が設けられ
ている。In these examples, the water pipe 3 remains straight, and a stopper 4 is provided slightly toward the end from the fin device position.
第３図の場合にはストッパとして通水管３に銅製のフラ
ンジ５がろう付けされている。In the case of FIG. 3, a copper flange 5 is brazed to the water pipe 3 as a stopper.
第４図の場合には、ろう盛り６が形成されている。In the case of FIG. 4, a braze filler 6 is formed.
第５図の場合には、銅製の肉厚円筒７がろう付けされて
いる。In the case of FIG. 5, a thick-walled copper cylinder 7 is brazed.
なお、屈曲部３ａおよびストッパ４とフィン１の端部と
の間隔はフィン１および通水管３の熱膨張を考慮して決
定される。Note that the distance between the bent portion 3a and the stopper 4 and the end of the fin 1 is determined in consideration of thermal expansion of the fin 1 and the water pipe 3.
この考案によれば通水管３がフィン装着位置からやや端
部側にて屈曲されているか、または通水管３のフィン装
着位置より端部側にストッパ４が設けられているので、
通水管３上におけるフィン１の移動を確実に防止するこ
とができる。According to this invention, the water pipe 3 is bent slightly toward the end from the fin mounting position, or the stopper 4 is provided at the end of the water pipe 3 from the fin mounting position.
Movement of the fins 1 on the water pipe 3 can be reliably prevented.
したがって、ヘッダとフィン付き管の接続部が破損する
おそれが全くない。Therefore, there is no possibility that the connection between the header and the finned tube will be damaged.
第１図はフィン付き管の一部省略斜視図、第２図、第３
図、第４図、第５図は一部省略縦断面図である。
１・・・・・・金属薄板、２・・・・・・嵌合溝部、３
・・・・・・通水路、４・・・・・・ストッパ。Figure 1 is a partially omitted perspective view of the finned tube, Figures 2 and 3.
Figures 4 and 5 are partially omitted longitudinal cross-sectional views. 1...Thin metal plate, 2...Fitting groove, 3
