本発明は、太陽熱利用の給湯器の熱交換器にお
ける集熱フイン装置に関する。DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a heat collecting fin device in a heat exchanger for a solar water heater.
従来の集熱フイン装置は、第１図、第２図に示
すとおりであり、フイン１′には長さ方向に円状
の溝部１a′が突設され、通水管２′がその内部に
挿通されて嵌合固着されている。通水管２′は溝
部１a′の内壁面１f′と密着するように取付けられ、
フイン１′にて集熱された熱を通水管２′内を通過
する流体に伝熱が充分に行われるようにしてい
る。 The conventional heat collection fin device is as shown in Figs. 1 and 2, and the fin 1' has a circular groove 1a' projecting in the length direction, and a water pipe 2' is inserted into the groove. It has been fitted and fixed. The water pipe 2' is installed so as to be in close contact with the inner wall surface 1f' of the groove 1a',
The heat collected by the fins 1' is sufficiently transferred to the fluid passing through the water pipe 2'.
このフイン１′は押出加工により成形されてお
り、そのため、フイン１′の肉厚を薄くすると、
押出加工時にその加工上、フイン１′が彎曲した
り、歪を生じ、通水管２′を密着状態に取付ける
ことができなかつた。 This fin 1' is formed by extrusion processing, so if the thickness of the fin 1' is made thinner,
During the extrusion process, the fins 1' were bent or distorted, making it impossible to attach the water pipe 2' tightly.
このため、フイン１′は肉厚が大となり、それ
だけ重量が大となるとともに、材料費も高くなり
不利益であつた。また、通水管とフインの密着は
フインの弾性によることになるが、温度変化によ
り密着が不完全になることが多かつた。 For this reason, the thickness of the fin 1' becomes large, which increases the weight and increases the material cost, which is disadvantageous. Furthermore, although the close contact between the water pipe and the fins is due to the elasticity of the fins, the close contact often becomes incomplete due to temperature changes.
本発明は、以上の欠点を改善し、軽量でかつ密
着性の良好な集熱フインを提供しようとするもの
である。 The present invention aims to improve the above-mentioned drawbacks and provide a heat collecting fin that is lightweight and has good adhesion.

着固定される。 The fin 1 is formed into the state shown in FIG. 5 by pressing, roll homing, etc. from a thin plate material, coil material, etc., and is manufactured without causing distortion or curvature. This is formed by forming a circular groove 1a in the length direction of the plate by pressing etc. A part of the circle becomes a notch A, and from 1b and 1c on both sides, a flat heat receiving part 1d and a heat receiving part 1d are formed. The portion 1e is bent horizontally. On the other hand, the water pipe 2 has a groove 2a recessed in the length direction, and the width of the groove 2a is larger than the notch A of the fin 1. Insert the water pipe 2 into the circular groove 1a of the fin 1, and
When the concave groove 2a of the water pipe is aligned with the notch A
Concave groove portions 2a are located on both sides of. There, notch A
Both ends 1b and 1c of the pipe 2 are bent inward so as to bite into the concave groove 2a of the water pipe 2, and the two are fixed together.
At that part, the fin 1 is in a double state, and as shown in FIGS. 3 and 4, the circular groove 1a of the fin 1 is
The inner wall surface 1f of the groove portion and the outer circumferential surface 2b of the water pipe 2 are tightly fixed.
端部１ｂ，１ｃが通水管２の凹状溝部２ａに食
い込むように折曲げられ、それによりフイン１と
通水管２との間の回動が阻止された状態となる。 The ends 1b and 1c are bent so as to bite into the concave groove 2a of the water pipe 2, thereby preventing rotation between the fin 1 and the water pipe 2.
以上のとおりであり、本発明によると、端部１

中の温度変化に対して密着状態が常に正常に維持
される。 As described above, according to the present invention, the end portion 1
b and 1c are bent to fit into the concave portion 2a of the water pipe 2, so the adhesion between the water pipe and the fins is very strong, and the plate material is doubled at the bent part, resulting in a strong retention force in the tight state. is large, and the adhesion state is always maintained normally despite temperature changes during use.
結局のところ、フインが薄板であり重量が軽く
なつたにもかかわらず、強度は大となり、永年の
使用中にも故障が起ることはなくなつた。 In the end, even though the fins were made of thin plates and were lighter in weight, the strength was greater, and failures did not occur even after many years of use.
