It intersects with the inner surface of the right side 11 of 1. and the inlet step 4
Contrary to the case of other parts, the cross-sectional area of the flow path that 0 faces expands from F 0 to F 1 as it goes from upstream to downstream. Furthermore, assuming that the width of the first flow path 21 immediately before the step portion 40 is G1 , H1 / G1 is determined to be 0.125 to 0.5. On the other hand, the height of the intermediate step portion 21b is

せるのに役立つ。 The cold water supplied into the heat collector from the cold water inlet 24a is warmed by absorbing solar heat while passing through the heat collector, and is sent out from the outlet 22a as hot water.
In the heat collector, the supply water is branched from the fourth flow path 24 through the first flow path 21 to a number of third flow paths, reaches the second flow path 22, and joins again. Therefore, in the first flow path 21, the water flow hits the inlet step 40 and is diverted, a part of which flows into several third flow paths near the upper side 14, and most of the other flow at the angle A. It easily descends along the sloped first flow path 21, hits the step portion 21b and is kicked off, and is reliably changed direction to the remaining third flow path 23. Since the first flow path 21 is formed to have a cross-sectional area that decreases as it goes downstream, approximately the same amount of water flows into each of the third flow paths 23. The branch seal part 33 of the fourth flow path 24 is reinforced with the main body of the heat collector.
This helps stabilize the water flow by diverting the feed water.
第３流路２３の両端において、細帯状シール部
は稍幅広の円弧状にシールされているため、凍結
時や加工時に剥離することがなく、しかもこの円
弧状境界線３２ｂは、下辺側にのみ凸状となるよ
う形成されているため、気泡が発生してもくびれ
部分に付着滞溜することなく排除される。 At both ends of the third flow path 23, the narrow strip-shaped seal portions are sealed in a slightly wide arc shape, so they will not peel off during freezing or processing, and this arc-shaped boundary line 32b is only on the lower side. Since it is formed in a convex shape, even if air bubbles are generated, they are removed without accumulating in the constriction.
また、第３流路２３は、角度Ｂ（1゜〜5゜）を有
するよう下流側が下るような流路とされたため、
前記発生空気泡は容易に下流側へ流下される。従
つて、気泡により集熱効率の低下を来たすことが
ない。 In addition, since the third flow path 23 was configured to have an angle B (1° to 5°) with its downstream side descending,
The generated air bubbles are easily flowed down to the downstream side. Therefore, the heat collection efficiency does not deteriorate due to air bubbles.
また、第３流路の断面はまゆ形とされ、第１辺

排除され易い。更に、第４流路２４は従来のもの
に比して楔形の大面積流路とされているため、水
自身の吸熱面積が拡大され、吸熱効率が高い。 Further, the cross section of the third flow path is cocoon-shaped, and the drain outlet 11a is located near the inlet of the first flow path 21 on the first side 11.
Since this is provided, it is possible to drain water to avoid freezing, and at the same time, it is possible to absorb volume expansion due to freezing of water. The cross section of the third channel 23 is slightly enlarged from the upstream side to the downstream side, so that frozen ice can be easily removed by descending. Furthermore, since the fourth flow path 24 is a wedge-shaped flow path with a larger area than the conventional one, the heat absorption area of the water itself is expanded and the heat absorption efficiency is high.
本考案の太陽熱集熱器は右辺１１が下方となる
姿勢（第１図において本体１０を右まわりに90度
回転させた状態）で使用されてもよい。 The solar heat collector of the present invention may be used with the right side 11 facing downward (the main body 10 is rotated 90 degrees clockwise in FIG. 1).
本考案は以上の如く構成されるので、集熱器全
体にわたり略均一な水流が得られ、器内に気泡が
滞溜することがなく、流れが円滑である。そして
高い集熱効率が得られる。 Since the present invention is constructed as described above, a substantially uniform water flow can be obtained over the entire heat collector, and the flow is smooth without the accumulation of air bubbles in the container. And high heat collection efficiency can be obtained.
特に第１辺の第１流路の入口付近にドレン出口

た。 In particular, since the drain outlet is provided near the inlet of the first flow path on the first side, it is possible to drain water to avoid freezing, and at the same time, volume expansion due to freezing of water can be absorbed. Further, in the vicinity of the maximum cross-sectional end of the first flow path on the downstream side of the drain outlet, on the inner surface on the first side side of the first flow path, an inlet of one of the third flow paths closest to the maximum cross-sectional end Since a step-like inlet step is provided at a position facing the large cross-section side to prevent the fluid from flowing from the large cross-section side to the small cross-section side, the water flow reaches the first flow path from the fourth flow path, and the inlet step When the third flow path hits the third flow path, the direction of the water is changed, and approximately the same amount of water flows into each of the third flow paths, further increasing the heat collection efficiency.

１項または第３項記載の太陽熱集熱器。[Scope of claims for utility model registration] (1) The first side, the second side, and the third side facing each other,
a first flow path along the first side, a second flow path along the second side, and the first and second flow paths. A large number of third channels connected to each other and parallel to each other through strip-shaped seal portions and inclined at an angle B with respect to the third and fourth sides, and one end connected to the largest cross-sectional end of the first channel. , the other end has a fourth passage passing through the second side and serving as a cold water inlet, the cross-sectional area of the first passage decreasing from the upstream side to the downstream side; The flow path is provided in a wedge-shaped portion left between the fourth side and the third flow path closest to the fourth side, and has a roughly wedge shape in plan view;
A drain outlet is provided near the inlet of the first flow path on the first side, and a drain outlet is provided on the first side of the first flow path in the vicinity of the maximum cross-sectional end of the first flow path on the downstream side of the drain outlet. On the inner surface, at a position facing one inlet of the third flow path closest to the end of the largest cross section, a stepped inlet step is provided to prevent fluid from flowing from the large cross section side to the small cross section side. A solar heat collector characterized by: (2) The solar heat collecting device according to claim 1, which is a utility model, wherein a narrow strip-shaped branching seal portion along the length of the flow path is provided near the cold water inlet of the fourth flow path. (3) The boundary line between the narrow strip seal portion and the third flow path is a straight line, the boundary line between the first and second flow paths is arc-shaped, and the arc-shaped boundary line is on the third side side. 2. The solar heat collector according to claim 1, which is a utility model registration device that intersects and continues with the straight line on the fourth side and smoothly continues with the straight line on the fourth side. (4) The third channel has a cocoon-shaped cross section and is slightly enlarged from the upstream side to the downstream side. Solar heat collector.
