Description

この発明は、太陽熱利用温水器等に使用される太陽熱集熱器の連結構造に関する。   The present invention relates to a connection structure for solar heat collectors used in solar water heaters and the like.

この種の太陽熱集熱器は、熱媒（水等）を通す熱媒流路が設けられた集熱板と、この熱媒流路が接続されるヘッダー管とがケーシング内に収容されており、例えば、図８に示すように、太陽熱集熱器のケーシング５１から突出しているヘッダー管５２の端部にヘッダー管継手５３をロウ付けし、両端部にＯリング５５が装着された連結管５４をヘッダー管継手５３に摺動自在に挿入し、図９（ａ）〜（ｃ）に示すように、金属片を屈曲及び湾曲させることによって形成されたファスナー部材５６を、そのスリット５６ａの間に、ヘッダー管継手５３の端部に形成されたフランジ部５３ａと連結管５４の端部側に形成されたフランジ部５４ａとを嵌め入れるようにして装着することにより、隣接する太陽熱集熱器同士を相互に連結するようになっている。   In this type of solar heat collector, a heat collecting plate provided with a heat medium flow path for passing a heat medium (water etc.) and a header pipe to which the heat medium flow path is connected are accommodated in a casing. For example, as shown in FIG. 8, a header pipe joint 53 is brazed to the end of the header pipe 52 protruding from the casing 51 of the solar heat collector, and a connecting pipe 54 having O-rings 55 attached to both ends. Is slidably inserted into the header pipe joint 53, and as shown in FIGS. 9A to 9C, a fastener member 56 formed by bending and bending a metal piece is interposed between the slits 56a. By mounting the flange portion 53a formed at the end portion of the header pipe joint 53 and the flange portion 54a formed at the end portion side of the connecting pipe 54, the adjacent solar heat collectors are attached to each other. To be interconnected To have.

このように、ファスナー部材５６を用いて、ヘッダー管継手５３と連結管５４とを接続しておくと、ヘッダー管継手５３から連結管５４が脱落することがなく、しかも、熱媒の温度変化に伴い、ヘッダー管５２、ヘッダー管継手５３及び連結管５４が伸縮した場合であっても、ファスナー部材５６に形成されたスリット５６ａがある程度の幅を有しているので、ヘッダー管継手５３に挿入された連結管５４が、ファスナー部材５６のスリット５６ａの幅の範囲内で自由に摺動することができ、ヘッダー管５２等の伸縮を確実に吸収することができるという利点がある。   Thus, if the header pipe joint 53 and the connection pipe 54 are connected using the fastener member 56, the connection pipe 54 will not drop out of the header pipe joint 53, and the temperature of the heat medium will change. Accordingly, even when the header pipe 52, the header pipe joint 53, and the connecting pipe 54 are expanded and contracted, the slit 56a formed in the fastener member 56 has a certain width, so that it is inserted into the header pipe joint 53. Further, the connecting pipe 54 can freely slide within the width of the slit 56a of the fastener member 56, and there is an advantage that the expansion and contraction of the header pipe 52 and the like can be reliably absorbed.

しかしながら、上述したようなファスナー部材５６は、ある程度の幅を有しており、しかも、ファスナー部材５６を着脱するためには、ある程度の作業スペースが必要になるので、こういったファスナー部材５６を用いてヘッダー管継手５３と連結管５４とを接続しようとすると、隣接する太陽熱集熱器との間にある程度の間隔を確保しなければならず、太陽熱集熱器の設置面積が大きくなるといった問題がある。   However, the fastener member 56 as described above has a certain width, and a certain amount of work space is required to attach and detach the fastener member 56. Therefore, such a fastener member 56 is used. If the header pipe joint 53 and the connecting pipe 54 are to be connected to each other, a certain distance must be ensured between the adjacent solar heat collectors, which increases the installation area of the solar heat collector. is there.

特に、太陽熱集熱器に太陽電池が搭載された光・熱ハイブリッドモジュールと、この光・熱ハイブリッドモジュールと同一デザインに統一された、太陽電池のみが搭載されている光モジュールとを併設する場合、光モジュール同士は配線で接続するだけなので、光モジュール同士の間隔については極端に小さくすることが可能であるが、上述したように、太陽熱集熱器のヘッダー管を接続しなければならない光・熱ハイブリッドモジュール同士の間隔については極端に小さくすることができない。従って、光・熱ハイブリッドモジュールと光モジュールとを併設する場合は、デザイン上、光モジュール同士の間隔だけを小さくすることはできず、光・熱ハイブリッドモジュール同士の間隔に合わせて、光モジュール同士の間隔を必要以上に大きく設定しなければならないので、設置数の多い光モジュールを効率よく設置することができないといった問題がある。   In particular, when an optical / thermal hybrid module in which a solar cell is mounted on a solar heat collector and an optical module in which only the solar cell is mounted, which is unified in the same design as the optical / thermal hybrid module, Since the optical modules are simply connected by wiring, the distance between the optical modules can be made extremely small. However, as described above, the light and heat that must be connected to the header tube of the solar heat collector. The distance between the hybrid modules cannot be made extremely small. Therefore, when the optical / thermal hybrid module and the optical module are provided side by side, the distance between the optical modules cannot be reduced due to the design, and the optical modules are arranged in accordance with the distance between the optical / thermal hybrid modules. Since the interval must be set larger than necessary, there is a problem that an optical module having a large number of installations cannot be installed efficiently.

そこで、この発明の課題は、太陽熱集熱器同士の間隔を小さく抑えることができる太陽熱集熱器の連結構造を提供することにある。   Then, the subject of this invention is providing the connection structure of the solar-heat collector which can suppress the space | interval of solar-heat collectors small.

以下、実施の形態について図面を参照して説明する。図１（ａ）、（ｂ）は、太陽熱を利用して温水を生成する集熱機能及び太陽光を利用して発電を行う発電機能を兼ね備えた太陽光発電／集熱積層型ハイブリッドモジュール（以下、ハイブリッドモジュールという。）１０の設置状態を示している。このハイブリッドモジュール１０は、図５に示すように、上面開口が透明な板ガラス１２によって閉塞される金属ケーシング１１内に、下面側に形成された把持部１３ａに銅製の通水管１４が把持されたアルミニウム製の集熱板１３と、この集熱板１３の上面側に接着剤を介して積層されたアモルファス太陽電池等の薄膜系太陽電池１５と、通水管１４が接続されるヘッダー管１６とが収容されており、ヘッダー管１６の端部には、金属ケーシング１１の側面から先端部が突出するように、ヘッダー管継手１７がロウ付けされている。   Hereinafter, embodiments will be described with reference to the drawings. 1 (a) and 1 (b) illustrate a solar power generation / heat collection stacked hybrid module (hereinafter referred to as a solar power generation / heat collection stacked type hybrid module) having both a heat collection function for generating hot water using solar heat and a power generation function for generating power using sunlight. , Referred to as a hybrid module). As shown in FIG. 5, this hybrid module 10 is made of aluminum in which a copper water pipe 14 is gripped by a gripping portion 13 a formed on the lower surface side in a metal casing 11 whose upper surface opening is closed by a transparent plate glass 12. A heat collecting plate 13 made of metal, a thin-film solar cell 15 such as an amorphous solar cell laminated on the upper surface side of the heat collecting plate 13 with an adhesive, and a header tube 16 to which the water pipe 14 is connected are accommodated. The header pipe joint 17 is brazed to the end portion of the header pipe 16 so that the tip end portion protrudes from the side surface of the metal casing 11.

このハイブリッドモジュール１０は、図１〜図５に示すように、平行に配設された一対の架台２１、２１の上に載置した状態で、隣接するハイブリッドモジュール１０のヘッダー管１６同士をヘッダー管接続手段によって相互に接続し、ケーシング固定手段を用いて、金属ケーシング１１を架台２１に固定するようになっている。   As shown in FIGS. 1 to 5, the hybrid module 10 is configured such that header tubes 16 of adjacent hybrid modules 10 are connected to each other in a state where the hybrid tubes 10 are placed on a pair of gantry 21, 21 arranged in parallel.

固定金具２２は、図５に示すように、隣接するハイブリッドモジュール１０の金属ケーシング１１間に挟み込まれることで、隣接するハイブリッドモジュール１０間の隙間を所定幅に保持する隙間保持部２２ａと、この隙間保持部２２ａにおける幅方向の両側部から水平に張り出して、隣接するハイブリッドモジュール１０の金属ケーシング１１における上面周縁部に掛止される掛止部２２ｂとを備えており、隙間保持部２２ａには、固定ボルト２３の軸部が挿通されるボルト挿通穴２２ｃが形成されている。   As shown in FIG. 5, the fixing bracket 22 is sandwiched between the metal casings 11 of the adjacent hybrid modules 10, so that a gap holding portion 22 a that holds a gap between the adjacent hybrid modules 10 to a predetermined width, and this gap The holding part 22a is provided with a hooking part 22b that extends horizontally from both sides in the width direction and is hooked on the peripheral edge of the upper surface of the metal casing 11 of the adjacent hybrid module 10, and the gap holding part 22a includes: A bolt insertion hole 22c through which the shaft portion of the fixing bolt 23 is inserted is formed.

従って、図４に示すように、隣接するハイブリッドモジュール１０の金属ケーシング１１によって、固定金具２２の隙間保持部２２ａを挟み込むように、隣接するハイブリッドモジュール１０を架台２１上に載置した状態で、固定金具２２の掛止部２２ｂを金属ケーシング１１における上面周縁部に掛止する。そして、固定金具２２の隙間保持部２２ａに形成されたボルト挿通穴２２ｃに、固定ボルト２３の軸部を挿通し、架台２１に形成されているネジ穴２１ａに固定ボルト２３をねじ込むと、固定金具２２の掛止部２２ｂによって、金属ケーシング１１が架台２１に押し付けられ、隣接するハイブリッドモジュール１０が所定幅の隙間を開けた状態で架台２１に固定される。   Accordingly, as shown in FIG. 4, the metal casing 11 of the adjacent hybrid module 10 is fixed in a state where the adjacent hybrid module 10 is placed on the gantry 21 so as to sandwich the gap holding portion 22 a of the fixing bracket 22. The latching portion 22 b of the metal fitting 22 is latched on the peripheral edge of the upper surface of the metal casing 11. Then, when the shaft portion of the fixing bolt 23 is inserted into the bolt insertion hole 22c formed in the gap holding portion 22a of the fixing bracket 22 and the fixing bolt 23 is screwed into the screw hole 21a formed in the mount 21, the fixing bracket 23 22, the metal casing 11 is pressed against the gantry 21 and the adjacent hybrid module 10 is fixed to the gantry 21 with a gap of a predetermined width.

以上のように、このハイブリッドモジュール１０の連結構造では、固定金具２２及び固定ボルト２３からなるケーシング固定手段によって、隣接するハイブリッドモジュール１０を架台２１に固定すると、隣接するハイブリッドモジュール１０間の隙間が所定幅に保持され、しかも、ヘッダー管継手１７に嵌入された連結管２４は、その端面がヘッダー管継手１７の段部１７ａに当接することによって、ヘッダー管１６側に必要以上に移動しないようになっているので、ヘッダー管１６にロウ付けされたヘッダー管継手１７に連結管２４を単に嵌入した状態で、隣接するハイブリッドモジュール１０をケーシング固定手段によって架台２１に固定すると、ヘッダー管継手１７と連結管２４とをあえて連結しなくても、ヘッダー管継手１７に嵌入された連結管２４がヘッダー管継手１７から脱落することがなく、ファスナー部材を使用してヘッダー管継手と連結管とを接続している従来の連結構造に比べて、隣接するハイブリッドモジュール１０間の隙間を小さくすることができる。   As described above, in this hybrid module 10 connection structure, when the adjacent hybrid module 10 is fixed to the mount 21 by the casing fixing means including the fixing bracket 22 and the fixing bolt 23, a gap between the adjacent hybrid modules 10 is predetermined. The connecting pipe 24 held in the width and fitted into the header pipe joint 17 does not move more than necessary to the header pipe 16 side because its end surface abuts on the stepped portion 17a of the header pipe joint 17. Therefore, when the adjacent hybrid module 10 is fixed to the mount 21 by the casing fixing means in a state where the connecting pipe 24 is simply inserted into the header pipe joint 17 brazed to the header pipe 16, the header pipe joint 17 and the connecting pipe are connected. Fits into the header fitting 17 even if it is not connected Compared to the conventional coupling structure in which the header pipe joint and the coupling pipe are connected using a fastener member without the dropped coupling pipe 24 falling off the header pipe joint 17, it is between the adjacent hybrid modules 10. The gap can be reduced.

また、ヘッダー管継手１７に嵌入された連結管２４は、上述したように、液密状態を維持したまま、ヘッダー管１６の接続方向に摺動することができるので、従来の連結構造と同様に、ヘッダー管１６等の伸縮を吸収することができることはいうまでもない。   Further, as described above, the connecting pipe 24 fitted into the header pipe joint 17 can slide in the connecting direction of the header pipe 16 while maintaining a liquid-tight state, and thus, similarly to the conventional connecting structure. Needless to say, the expansion and contraction of the header tube 16 and the like can be absorbed.

なお、上述した実施形態では、ヘッダー管継手１７に連結管２４が嵌入（内嵌）されるタイプのヘッダー管接続手段を採用しているが、これに限定されるものではなく、ヘッダー管継手に連結管が外嵌されるタイプのヘッダー管接続手段を採用することも可能である。ただし、そのようなヘッダー管接続手段を採用する場合も、ヘッダー管継手に外嵌された連結管が、液密状態でヘッダー管の接続方向に摺動するようにしておく必要があることはいうまでもない。   In the above-described embodiment, the header pipe connecting means of the type in which the connecting pipe 24 is fitted (internally fitted) into the header pipe joint 17 is adopted, but the present invention is not limited to this, and the header pipe joint is not limited to this. It is also possible to adopt a header pipe connecting means of a type in which the connecting pipe is fitted. However, even when such a header pipe connecting means is adopted, it is necessary that the connecting pipe externally fitted to the header pipe joint should be slid in the connecting direction of the header pipe in a liquid-tight state. Not too long.

また、上述した実施形態では、ヘッダー管接続手段を、ヘッダー管１６の端部にロウ付けされたヘッダー管継手１７と、このヘッダー管継手１７に嵌入される連結管２４とによって構成しているが、これに限定されるものではなく、例えば、図６に示すハイブリッドモジュール１０Ａのように、ヘッダー管１６の一端側にロウ付けされた、Ｏリング１８が装着された雄側ヘッダー管継手１７Ａと、ヘッダー管１６の他端側にロウ付けされた、雄側ヘッダー管継手１７Ａを嵌入可能な雌側ヘッダー管継手１７Ｂとによって構成することも可能であり、こういったヘッダー管接続手段を採用する場合は、隣接する一方のハイブリッドモジュール１０Ａの雄側ヘッダー管継手１７Ａを、隣接する他方のハイブリッドモジュール１０Ａの雌側ヘッダー管継手１７Ｂに単に嵌入した状態で、隣接するハイブリッドモジュール１０Ａをケーシング固定手段によって架台２１に固定すればよい。ただし、ヘッダー管１６等の伸縮を吸収するためには、雄側ヘッダー管継手１７Ａ及び雌側ヘッダー管継手１７Ｂが、液密状態で接近離反可能に嵌合しなければならないことはいうまでもない。   In the above-described embodiment, the header pipe connecting means is configured by the header pipe joint 17 brazed to the end of the header pipe 16 and the connecting pipe 24 fitted into the header pipe joint 17. However, the present invention is not limited to this, for example, a male side header pipe joint 17A fitted with an O-ring 18 brazed to one end side of the header pipe 16 like a hybrid module 10A shown in FIG. It is also possible to configure with a female header pipe joint 17B that can be fitted with a male header pipe joint 17A brazed to the other end of the header pipe 16, and when such header pipe connection means is adopted. The male header fitting 17A of one adjacent hybrid module 10A is replaced with the female header of the other adjacent hybrid module 10A. While simply fitted into the fitting 17B, the adjacent hybrid module 10A may be fixed to the frame 21 by a casing fixing means. However, it goes without saying that in order to absorb the expansion and contraction of the header pipe 16 and the like, the male header pipe joint 17A and the female header pipe joint 17B must be fitted in a liquid-tight state so as to be able to approach and separate. .

また、上述した実施形態では、隣接するハイブリッドモジュール１０間の隙間を所定幅に保持する固定金具２２と、この固定金具２２を介してハイブリッドモジュール１０の金属ケーシング１１を架台２１に固定する固定ボルト２３とから構成されたケーシング固定手段を採用しているが、これに限定されるものではなく、例えば、図７（ａ）、（ｂ）に示すように、架台２１の外側面に、固定ボルト３２の軸部が挿通されるボルト挿通用の長穴３１ａが形成された連結片３１を溶接固定し、連結片３１に形成された長穴３１ａに固定ボルト３２の軸部を挿通した状態で、金属ケーシング１１の側面に形成されたネジ穴１１ａに固定ボルト３２をねじ込むことにより、連結片３１を介して、隣接するハイブリッドモジュール１０の金属ケーシング１１を架台２１に固定するようなケーシング固定手段を採用することも可能である。   In the above-described embodiment, the fixing bracket 22 that holds the gap between the adjacent hybrid modules 10 at a predetermined width, and the fixing bolt 23 that fixes the metal casing 11 of the hybrid module 10 to the mount 21 via the fixing bracket 22. However, the present invention is not limited to this. For example, as shown in FIGS. 7A and 7B, the fixing bolt 32 is provided on the outer surface of the gantry 21. In the state where the connecting piece 31 in which the elongated hole 31a for inserting the bolt is inserted is fixed by welding, and the shaft portion of the fixing bolt 32 is inserted into the elongated hole 31a formed in the connecting piece 31. By screwing the fixing bolt 32 into the screw hole 11a formed on the side surface of the casing 11, the metal casing of the adjacent hybrid module 10 is connected via the connecting piece 31. It is also possible to employ a casing fixing means such as fixing the grayed 11 to the frame 21.

また、上述した各実施形態では、集熱機能と発電機能とを兼ね備えたハイブリッドモジュール１０、１０Ａ同士の連結構造について説明したが、これに限定されるものではなく、本発明の連結構造は、発電機能を備えていない太陽熱集熱器同士を連結する場合や、ハイブリッドモジュールと太陽熱集熱器とを連結する場合にも適用することができることはいうまでもない。   Moreover, although each embodiment mentioned above demonstrated the connection structure of the hybrid modules 10 and 10A which have the heat collection function and the electric power generation function, it is not limited to this, The connection structure of this invention is an electric power generation. Needless to say, the present invention can also be applied to a case where solar heat collectors having no function are connected to each other, or a case where a hybrid module and a solar heat collector are connected.
