Description

本発明は、太陽電池パネルの高温による発電効率の低下を防止し、且つその熱を回収する技術に関する。   The present invention relates to a technique for preventing a decrease in power generation efficiency due to a high temperature of a solar cell panel and recovering the heat.

単結晶型や多結晶型の太陽電池パネルは、表面温度が高温になると発電効率が低下する。これに対し、太陽電池パネルの熱を吸収して冷却する技術が特許文献１に開示されている。この技術は、太陽電池パネルの裏面に水を流すパイプを熱伝導材で密接し、そのパイプと熱伝導材を断熱材が充填された枠材で被覆して一体化したことを特徴としている。この技術によれば、パイプ内の水に太陽電池パネルの熱が吸収されて電気への熱変換効率が改善され、しかも熱を吸収した水を暖房や給湯に利用することで総合効率も向上できる、というものである。   Single-crystal and polycrystalline solar cell panels have lower power generation efficiency when the surface temperature becomes high. On the other hand, Patent Document 1 discloses a technique for absorbing and cooling the heat of the solar cell panel. This technology is characterized in that a pipe for flowing water is in close contact with the back surface of the solar cell panel with a heat conducting material, and the pipe and the heat conducting material are covered and integrated with a frame material filled with a heat insulating material. According to this technology, the heat in the solar panel is absorbed by the water in the pipe to improve the efficiency of heat conversion to electricity, and the overall efficiency can also be improved by using the water that has absorbed the heat for heating and hot water supply. That's it.

ところで、前記技術の装置は太陽電池パネルと一体的な構造であるから、様々なメーカーの新設又は既設の太陽電池パネルに後付けすることは困難であった。また、装置を交換又は修理する場合は、太陽電池パネルを屋根から取り外して分解する必要があり、作業が煩雑で時間がかかるものであった。   By the way, since the apparatus of the said technique is a structure integral with a solar cell panel, it was difficult to retrofit to the new or existing solar cell panel of various manufacturers. In addition, when replacing or repairing the device, it is necessary to remove the solar cell panel from the roof and disassemble it, and the work is complicated and takes time.

The back plate is preferably made of a metal having a low thermal conductivity or a non-metal such as plastic so that the heat of the solar cell panel can be transferred to the heat collecting tube as much as possible. Embodiments of the present invention will be specifically described below with reference to the drawings.

本実施例の熱回収装置１は、図１，２に示すように、良伝熱性の平坦な集熱板２と、その集熱板２の下面に一体的に取り付けて内部に熱媒体である液体を流す集熱管３と、その集熱管３を集熱板２に取り付けるアルミテープ４（良伝熱性の粘着テープ）と、集熱管３及び集熱板２の下面側を覆うための圧縮されると復元力を生じる断熱体５と、その断熱体５の下面を覆う裏板６と、その裏板６とパネル取付鋼材１１（取付架台）の間に配置して集熱板２を太陽電池パネル１０の裏面に押え付ける押さえ具７で一体的に構成している。   As shown in FIGS. 1 and 2, the heat recovery apparatus 1 of the present embodiment is a heat medium that is integrally attached to the lower surface of the heat collecting plate 2 and the heat collecting plate 2 that has good heat transfer properties. A heat collecting tube 3 for flowing a liquid, an aluminum tape 4 (good heat transfer adhesive tape) for attaching the heat collecting tube 3 to the heat collecting plate 2, and compressed to cover the lower surface side of the heat collecting tube 3 and the heat collecting plate 2. And a heat insulator 5 that generates restoring force, a back plate 6 that covers the lower surface of the heat insulator 5, and a heat collecting plate 2 that is disposed between the back plate 6 and the panel mounting steel material 11 (mounting mount). The presser 7 that presses against the back surface of 10 is integrally formed.

集熱板２は厚さ０．８ｍｍの平滑な銅板で構成され、中間の位置に４本のスタッドボルト２ａを一定間隔おいて溶接し、周片を直角に折り曲げて側板２ｂを形成している。   The heat collecting plate 2 is formed of a smooth copper plate having a thickness of 0.8 mm, and four stud bolts 2a are welded at a certain interval at an intermediate position, and the peripheral piece is bent at a right angle to form the side plate 2b. .

集熱管３は銅管で構成され、一定間隔で規則的に蛇行するように曲折している。その集熱管３を集熱板２の下面に配置して入口と出口の部分を集熱板２の側板２ｂに貫通し、その集熱管３を覆うようにアルミテープ４を貼り付けて集熱板２に固定している。   The heat collecting tube 3 is made of a copper tube and is bent so as to meander regularly at regular intervals. The heat collecting tube 3 is disposed on the lower surface of the heat collecting plate 2, the inlet and outlet portions are passed through the side plate 2 b of the heat collecting plate 2, and the aluminum tape 4 is attached so as to cover the heat collecting tube 3. 2 is fixed.

断熱体５は圧縮されると復元力が生じる硬さの発泡スチロール板で構成され、集熱板２のスタッドボルト２ａに突き刺して集熱板２と集熱管３を覆っている。スタッドボルト２ａは断熱体５から突出する。   The heat insulator 5 is formed of a styrofoam plate having a hardness that generates a restoring force when compressed, and pierces the stud bolt 2 a of the heat collecting plate 2 to cover the heat collecting plate 2 and the heat collecting tube 3. The stud bolt 2 a protrudes from the heat insulator 5.

裏板６は鋼板で構成され、断熱体５から突出しているスタッドボルト２ａに合せた位置にボルト穴を開口し、周片を直角に折り曲げて側板６ａを形成している。その裏板６のボルト穴をスタッドボルト２ａに掛けて断熱体５を覆い、側板６ａを集熱板２の側板２ｂの内側に嵌挿して箱状に形成している。側板６ａ，２ｂ同士は、砂・雨水・虫等の進入が防止でき且つ集熱板２が上下動できる狭い間隔をおいて配置するのが望ましい。スタッドボルト２ａは裏板６から突出する。   The back plate 6 is made of a steel plate, and a bolt hole is opened at a position corresponding to the stud bolt 2a protruding from the heat insulator 5, and the peripheral piece is bent at a right angle to form the side plate 6a. A bolt hole of the back plate 6 is hung on the stud bolt 2 a to cover the heat insulator 5, and the side plate 6 a is fitted inside the side plate 2 b of the heat collecting plate 2 to form a box shape. It is desirable that the side plates 6a and 2b be arranged at a narrow interval so that sand, rainwater, insects and the like can be prevented from entering and the heat collecting plate 2 can move up and down. The stud bolt 2a protrudes from the back plate 6.

押さえ具７は断面Ｌ字状に折り曲げた長尺の鋼材で構成され、裏板６から突出しているスタッドボルト２ａに合せた位置にボルト穴を開口している。その押さえ具７のボルト穴をスタッドボルト２ａに掛け、ナット７ａを所定位置まで締めている。この状態で裏板６と押さえ具７は断熱体５の圧縮及び復元に応じてスタッドボルト２ａに沿って若干上下動できる。   The presser 7 is made of a long steel material bent into an L-shaped cross section, and has a bolt hole opened at a position corresponding to the stud bolt 2 a protruding from the back plate 6. The bolt hole of the presser 7 is hung on the stud bolt 2a, and the nut 7a is tightened to a predetermined position. In this state, the back plate 6 and the presser 7 can move up and down slightly along the stud bolt 2a in accordance with the compression and restoration of the heat insulator 5.

本実施例では、図３（ａ）に示すように、ナット１１ｂを外して太陽電池パネル１０をパネル取付鋼材１１から若干浮かせ、その間の空間に熱回収装置１を挿入する。その後、図３（ｂ）及び図４に示すように、太陽電池パネル１０を元の位置に戻すと、太陽電池パネル１０が集熱板２を押し下げて断熱体５が若干圧縮し、その圧縮された断熱体５の復元力で集熱板２が太陽電池パネル１０の裏面に強く圧接する。このようにして、複数連設された各太陽電池パネル１０の裏面に熱回収装置１をそれぞれ設置する。なお、設置後は強風等に備えて押さえ具７を横鋼材１２にボルト等で固定しても良い。   In the present embodiment, as shown in FIG. 3A, the nut 11b is removed to slightly lift the solar cell panel 10 from the panel mounting steel material 11, and the heat recovery device 1 is inserted into the space therebetween. Thereafter, as shown in FIGS. 3B and 4, when the solar cell panel 10 is returned to the original position, the solar cell panel 10 pushes down the heat collecting plate 2, and the heat insulating body 5 is slightly compressed and compressed. The heat collecting plate 2 is strongly pressed against the back surface of the solar cell panel 10 by the restoring force of the heat insulator 5. In this manner, the heat recovery apparatus 1 is installed on the back surface of each of the solar cell panels 10 provided in series. In addition, you may fix the pressing tool 7 to the horizontal steel material 12 with a volt | bolt etc. in preparation for a strong wind etc. after installation.

そして、熱回収装置１の集熱管３の出口と隣接する別の熱回収装置１の集熱管３の入口をそれぞれ直列に接続し、図５に示すように、最上流側と最下流側の熱回収装置１を水熱交換器１４に接続し、熱媒体用の水を供給して各熱回収装置１に循環させる。太陽光が太陽電池パネル１０に照射されると電気への熱変換が行われ、その際に発生した熱が集熱板２及びアルミテープ４を通じて集熱管３内の水に伝わる。回収した熱は給水予熱槽１５で給湯用の水と熱交換され、給湯貯湯槽１６に貯湯して給湯に利用される。交換又は修理する場合は、太陽電池パネル１０をパネル取付鋼材１１から若干浮かせ、熱回収装置１を取り出して行う。   Then, the outlet of the heat collecting pipe 3 of the heat recovery apparatus 1 and the inlet of the heat collecting pipe 3 of another heat recovery apparatus 1 adjacent to each other are connected in series, respectively, and as shown in FIG. The recovery device 1 is connected to the water heat exchanger 14, and water for the heat medium is supplied and circulated to each heat recovery device 1. When the solar cell panel 10 is irradiated with sunlight, heat is converted into electricity, and the heat generated at that time is transmitted to the water in the heat collecting tube 3 through the heat collecting plate 2 and the aluminum tape 4. The recovered heat is heat-exchanged with water for hot water supply in the hot water preheating tank 15 and stored in the hot water hot water storage tank 16 to be used for hot water supply. When exchanging or repairing, the solar battery panel 10 is slightly lifted from the panel mounting steel 11 and the heat recovery apparatus 1 is taken out.

本実施例の熱回収装置１を取り付けた場合と取り付けない場合の太陽電池パネル１０の裏面温度の違い等について実験した。図６の上のグラフに示すように、熱回収装置１を取り付けた場合の裏面温度が取り付けない場合と比較して平均１０．２℃低下した。集熱管３の入口と出口の水温差は平均６．６℃であった。また、図６の下のグラフに示すように、時刻が１２時における太陽電池パネル１０の発電量が１００Ｗ／ｍ２で発電効率は１１．６％であったが、熱回収装置１による集熱量が３８３Ｗ／ｍ２であり、総合効率は５５．８％となった。このように、本実施例の熱回収装置１は、太陽電池パネル１０に後付けできる構造でありながら、十分な熱回収性能を有している。 An experiment was conducted on the difference in the temperature of the back surface of the solar cell panel 10 when the heat recovery apparatus 1 of this example was attached and when it was not attached. As shown in the upper graph of FIG. 6, the back surface temperature when the heat recovery apparatus 1 was attached was an average of 10.2 ° C. lower than the case where it was not attached. The average water temperature difference between the inlet and outlet of the heat collecting tube 3 was 6.6 ° C. As shown in the lower graph of FIG. 6, the power generation amount of the solar cell panel 10 at 12:00 was 100 W / m 2 and the power generation efficiency was 11.6%. Was 383 W / m 2 , and the overall efficiency was 55.8%. Thus, the heat recovery apparatus 1 of the present embodiment has a sufficient heat recovery performance while having a structure that can be retrofitted to the solar cell panel 10.

図７，８に示すのは、集熱板を太陽電池パネルの裏面に押さえ付ける付勢手段を設けた実施例の熱回収装置の他の例である。図７，８に示すように、ボルト穴が開口された銅製の押さえ板８（良伝熱性の取付具）をスタッドボルト２ａに掛けてナット８ａで集熱管３を集熱板２に固定し、そのナット８ａと裏板６の間に圧縮コイルバネ９を介装している。また、図７に示す断熱体５はグラスウールを用い、図８に示す断熱体５は粒状物を用いて集熱板２と裏板６の間の空間に充填している。集熱板２の側板２ｂは裏板６の側板６ａの内側にわずかな間隔をおいて配置している。   FIGS. 7 and 8 show another example of the heat recovery apparatus of the embodiment provided with a biasing means for pressing the heat collecting plate against the back surface of the solar cell panel. As shown in FIGS. 7 and 8, a copper holding plate 8 (a good heat transfer fixture) with a bolt hole opened is hung on a stud bolt 2a, and the heat collecting tube 3 is fixed to the heat collecting plate 2 with a nut 8a. A compression coil spring 9 is interposed between the nut 8 a and the back plate 6. Moreover, the heat insulator 5 shown in FIG. 7 uses glass wool, and the heat insulator 5 shown in FIG. 8 uses a granular material to fill the space between the heat collecting plate 2 and the back plate 6. The side plate 2b of the heat collecting plate 2 is disposed inside the side plate 6a of the back plate 6 with a slight gap.

これらの例では、圧縮コイルバネ９の反発力でナット８ａが押し上げられ、集熱板２が太陽電池パネル１０の裏面に強く圧接される。したがって、断熱体５に復元力の小さいグラスウールや粒状物を用いても、実施例と同等の熱回収性能を発揮できる。また、銅製の押さえ板８によって集熱管３が集熱板２に強く密接して伝熱性が向上し、その押さえ板８を通じて集熱板２の熱が集熱管３内の水により迅速に伝わる。また、集熱板２の側板２ｂが裏板６の側板６ａの内側に嵌挿されているから、集熱板２に回収された熱が外部に放熱され難くなり、熱回収性能がより優れたものとなる。特に、図７の例では、集熱板２の側板２ｂが断熱体５のグラスウールに食い込み、側板２ｂと側板６ａの間の空隙が閉塞されて断熱性も向上する。その他、符号、構成、作用効果は実施例と同じである。   In these examples, the nut 8 a is pushed up by the repulsive force of the compression coil spring 9, and the heat collecting plate 2 is strongly pressed against the back surface of the solar cell panel 10. Therefore, even if glass wool or a granular material with a small restoring force is used for the heat insulator 5, heat recovery performance equivalent to that of the embodiment can be exhibited. Further, the heat collecting tube 3 is strongly in close contact with the heat collecting plate 2 by the copper holding plate 8 to improve the heat transfer property, and the heat of the heat collecting plate 2 is quickly transmitted to the water in the heat collecting tube 3 through the holding plate 8. Moreover, since the side plate 2b of the heat collecting plate 2 is fitted inside the side plate 6a of the back plate 6, the heat collected in the heat collecting plate 2 is hardly radiated to the outside, and the heat collecting performance is more excellent. It will be a thing. In particular, in the example of FIG. 7, the side plate 2 b of the heat collecting plate 2 bites into the glass wool of the heat insulator 5, and the gap between the side plate 2 b and the side plate 6 a is closed to improve the heat insulation. In other respects, the reference numeral, the configuration, and the operational effects are the same as in the embodiment.

図９〜１１に示すのは、集熱板の側板と裏板の側板の間にプラスチック等の熱伝導性の低い断熱部材を設けた実施例の熱回収装置の他の例である。図９に示すのは、集熱板２の側板２ｂの外面から下端に渡って薄い断熱板２ｃを付着している。図１０に示すのは、集熱板２の側板２ｂに厚みを有する断面Ｕ字状の断熱カバー体２ｄを側板２ｂの内外表面の断熱部材としてネジで取り付けている。この例は、側板２ｂからの放熱を断熱カバー体２ｄで抑え、集熱板２の熱を集熱管３へ吸熱させて熱回収効率を高めている。加えて、雨水・砂・虫の進入を効果的に防止できるものとなっている。図１１に示すのは、集熱板２の側板２ｂを省略し、厚みを有する断熱角材２ｅの上端に集熱板２の周片をネジで固定している。   FIGS. 9 to 11 show another example of the heat recovery apparatus of the embodiment in which a heat insulating member having low thermal conductivity such as plastic is provided between the side plate of the heat collecting plate and the side plate of the back plate. In FIG. 9, a thin heat insulating plate 2 c is attached from the outer surface to the lower end of the side plate 2 b of the heat collecting plate 2. In FIG. 10, a heat insulating cover body 2d having a U-shaped cross section having a thickness is attached to the side plate 2b of the heat collecting plate 2 as a heat insulating member on the inner and outer surfaces of the side plate 2b with screws. In this example, heat radiation from the side plate 2b is suppressed by the heat insulating cover body 2d, and heat of the heat collecting plate 2 is absorbed into the heat collecting tube 3 to increase heat recovery efficiency. In addition, rainwater, sand and insects can be effectively prevented. In FIG. 11, the side plate 2b of the heat collecting plate 2 is omitted, and the peripheral piece of the heat collecting plate 2 is fixed to the upper end of the heat insulating square 2e having a thickness with screws.

これらの例では、集熱板２の側板２ｂが裏板６の側板６ａに接触できない構造となっているから、集熱板２に回収された熱が集熱管３以外の部分に伝わり難くなり、熱回収性能が改善される。なお、集熱板２の側板２ｂは裏板６の側板６ａの外側又は内側のいずれに嵌挿しても良く、図７，８に示す圧縮コイルバネ９等の付勢手段を設けた構造に応用しても良い。その他、符号、構成、作用効果は実施例と同じである。   In these examples, since the side plate 2b of the heat collecting plate 2 has a structure that cannot contact the side plate 6a of the back plate 6, the heat recovered by the heat collecting plate 2 is difficult to be transmitted to portions other than the heat collecting tube 3, Heat recovery performance is improved. The side plate 2b of the heat collecting plate 2 may be inserted into either the outer side or the inner side of the side plate 6a of the back plate 6, and is applied to a structure provided with a biasing means such as a compression coil spring 9 shown in FIGS. May be. In other respects, the reference numeral, the configuration, and the operational effects are the same as in the embodiment.

図１２，図１３に示す実施例は、請求項９に記載の集熱管の取り付けに管取付体と押え板とを使用する例である。
The embodiment shown in FIGS. 12 and 13 is an example in which a pipe mounting body and a presser plate are used for mounting the heat collecting pipe according to claim 9 .

It is a rivet to do. The reference numerals of other terms are the same as in the previous embodiment.

管取付体１８は一つの太陽電池パネルに対して、４個列設して使用される。１つの管取付体１８の寸法は２００ｍｍ巾で長さ７８０ｍｍで厚みは１４ｍｍ程であり、一本のＵ字状の集熱管３の直線部を二条ある管抱持部１８ｃに嵌入した後１０００ｍｍ×８００ｍｍ程のアルミ素材の広巾の押え板１９にリベット２１で止着して４列の管取付板１８を押え板１９に固定して一体化する。集熱管３のＵ字の湾曲部は管取付体１８の上辺・下辺から外側に露出する。   Four tube attachments 18 are used in a row with respect to one solar cell panel. The dimensions of one tube mounting body 18 are 200 mm wide, 780 mm long, and about 14 mm thick. After the straight portion of one U-shaped heat collecting tube 3 is fitted into the two tube holding portions 18 c, 1000 mm × A wide holding plate 19 made of an aluminum material of about 800 mm is fastened with a rivet 21, and the four rows of pipe mounting plates 18 are fixed to and integrated with the holding plate 19. The U-shaped curved portion of the heat collecting tube 3 is exposed to the outside from the upper and lower sides of the tube attachment body 18.

Ｕ字状の集熱管３の管取付体１８の上辺・下辺から露出した湾曲部と直線部は、この露出した隣り合う集熱管３の管端の湾曲部と直線部の管端同士を溶接で接続して長い蛇管状とする。   The curved portion and the straight portion exposed from the upper and lower sides of the tube attachment body 18 of the U-shaped heat collecting tube 3 are welded to the exposed curved portion and the straight portion of the adjacent heat collecting tube 3. Connect to a long snake-tube.

集熱管３を４列の管取付板１８に取付けた後、押え板１９を下方から管取付体１８の下板部１８ｂにリベット２１で固定して一体化する。集熱管３の下端部は嵌入する管抱持部１８ｃの下方開口及び管取付体１８の下板部１８ｂより下方に突出しているので、押え板１９によって集熱管３は管抱持部１８ｃ内面に加圧され、集熱管３と管抱持部１８ｃは圧接され、伝熱を良好にしている。   After the heat collecting tubes 3 are attached to the four rows of tube mounting plates 18, the holding plate 19 is fixed to the lower plate portion 18 b of the tube mounting body 18 from below by the rivets 21 and integrated. Since the lower end portion of the heat collecting tube 3 projects downward from the lower opening 18b of the tube holding portion 18c to be fitted and the lower plate portion 18b of the tube mounting body 18, the heat collecting tube 3 is placed on the inner surface of the tube holding portion 18c by the presser plate 19. Pressurized, the heat collecting tube 3 and the tube holding portion 18c are in pressure contact to improve heat transfer.

裏板６とその周縁で上方に折曲した側板６ａで容器状になったその容器空間に発泡スチロールの断熱体５を敷き、その上に４列の押え板１９で一体的に連結された管取付体１８を置く。管取付体１８の上辺・下辺から露出した集熱管３の周囲の空間にファイバーグラスの断熱材２０を充填して断熱状態とする。   A pipe mounting in which a foamed polystyrene insulation 5 is placed in a container space formed by a back plate 6 and a side plate 6a bent upward at the periphery thereof, and integrally connected by four rows of press plates 19 thereon. Put the body 18 on. The space around the heat collecting tube 3 exposed from the upper side and the lower side of the tube attachment 18 is filled with a fiberglass heat insulating material 20 to be in a heat insulating state.

押え板１９と裏板６及び押さえ具７との間には、圧縮コイルバネ９が設けられ、管取付体１８及びその上方の集熱板２を上方に付勢するようにしている。集熱板２のその周縁は下方に折曲された側板２ｂを有して上箱状となっている。裏板６とその側板６ａで形成される容器（下箱）に対し、嵌合されて上下動可能な上箱となっている。太陽電池パネルの裏面に集熱板２を押し付けて、伝熱性を良好にしている。   A compression coil spring 9 is provided between the presser plate 19 and the back plate 6 and the presser 7 so as to urge the tube mounting body 18 and the heat collecting plate 2 thereabove upward. The peripheral edge of the heat collecting plate 2 has a side plate 2b bent downward and has an upper box shape. An upper box that can be moved up and down is fitted to a container (lower box) formed by the back plate 6 and its side plate 6a. The heat collecting plate 2 is pressed against the back surface of the solar cell panel to improve heat transfer.

本実施例では、管取付体１８は複数のリブ１８ｄと管抱持部１８ｃによって高い強度を有し、付勢力・加圧力で変形することなく、集熱板２を太陽電池パネル１０の裏面に押し付け、その密着性をよくして集熱板２の変形・変位による伝熱率の低下を防いでいる。   In the present embodiment, the tube mounting body 18 has high strength due to the plurality of ribs 18d and the tube holding portion 18c, and the heat collecting plate 2 is attached to the back surface of the solar cell panel 10 without being deformed by the biasing force / pressure force. The adhesion is improved by pressing, thereby preventing a decrease in heat transfer rate due to deformation and displacement of the heat collecting plate 2.

又、集熱板２の熱は伝熱係数がよいアルミ素材が使用された上板部１８ａ、リブ１８ｄ及び下板部１８ｂ、押え板１９を介して管抱持部１８ｃへ伝熱させることで伝熱効率を良好にする。又、集熱管３と管抱持部１８ｃとは押え板１９からの加圧で接触が良好で熱伝達がよくなっている。
