Description
本発明は、熱電変換装置の設置方法および熱電変換装置に関する。
The present invention relates to a thermoelectric conversion device installation method and a thermoelectric conversion device.
建物の外側に露出する外側壁と、外側壁よりも建物の内側に位置し外側壁との間に空間が形成された状態で配置された内側壁と、板状であり外側壁と内側壁との間において厚さ方向における一面が外側壁の内面に接触させた状態で外側壁に取り付けられた熱電変換部と、を含む建物の壁構造が提案されている（例えば特許文献１参照）。ここで、熱電変換部の厚さ方向における他面側は、外側壁と内側壁との間を流動する空気で冷却される。そして、熱電変換部は、厚さ方向における一面側の温度と厚さ方向における他面側の温度との温度差に応じて発電する。
An outer side wall exposed to the outside of the building, an inner side wall located inside the building rather than the outer side wall with a space formed between the outer side wall, and a plate-shaped outer side wall and the inner side wall. A wall structure of a building including a thermoelectric conversion unit attached to the outer wall with one surface in the thickness direction in contact with the inner surface of the outer wall is proposed (for example, see Patent Document 1). Here, the other surface side in the thickness direction of the thermoelectric conversion portion is cooled by air flowing between the outer wall and the inner wall. Then, the thermoelectric conversion unit generates power according to the temperature difference between the temperature on one surface side in the thickness direction and the temperature on the other surface side in the thickness direction.
しかしながら、特許文献１に記載された壁構造の場合、外側壁と内側壁との間を流動する空気が、外側壁から熱電変換部を通って伝達してくる熱により暖められてしまう。そうすると、熱電変換部の厚さ方向における一面側の温度と他面側の温度との温度差が小さくなり、熱電変換部の発電量が低下してしまう虞がある。
However, in the case of the wall structure described in Patent Document 1, the air flowing between the outer wall and the inner wall is warmed by the heat transferred from the outer wall through the thermoelectric conversion section. Then, the temperature difference between the temperature on the one surface side and the temperature on the other surface side in the thickness direction of the thermoelectric conversion portion becomes small, which may reduce the amount of power generation of the thermoelectric conversion portion.

The installation method for the thermoelectric conversion device according to the present embodiment is a building material that includes a first building material and a second building material that is arranged so as to be adjacent to the first building material in the thickness direction of the first building material. It is a method of installing a thermoelectric conversion device. Here, the thermoelectric conversion device has a first part and a second part different from the first part, and generates power according to the temperature difference between the temperature of the first part and the temperature of the second part. Then, in this method of installing the thermoelectric conversion device, the first portion is exposed to the side opposite to the second construction material side of the first construction material from the opening formed in the first construction material, and the second portion is 2 The thermoelectric conversion device is installed in the building material while being thermally coupled to the building material. Here, “thermally coupled” means that heat is transferred between the second construction material and the second portion, for example. The case where heat is conducted between the second construction material and the second portion via a resin or a sheet is also included.
例えば図１に示すように、本実施の形態に係る熱電変換装置１は、建物の壁Ｗａ１０の外側に露出するように壁Ｗａ１０に設置される。熱電変換装置１は、図２Ａに示すように、複数の熱電変換素子１１と、第１伝熱部材１２と、第２伝熱部材１３と、断熱部材１４と、を備える。また、複数の熱電変換素子１１は、第１伝熱部材１２と第２伝熱部材１３との間に配置されている。複数の熱電変換素子１１は、それぞれ、いわゆるπ型の熱電変換素子或いは積層型の熱電変換素子であり、第１伝熱部材１２に熱的に結合した部分と第２伝熱部材１３に熱的に結合した部分とを有する。そして、複数の熱電変換素子１１は、それぞれ、第１伝熱部材１２に熱的に結合した部分の温度と第２伝熱部材１３に熱的に結合した部分の温度との温度差に応じて発電する。複数の熱電変換素子１１それぞれの発電量は、第１伝熱部材１２に熱的に結合した部分の温度と第２伝熱部材１３に熱的に結合した部分の温度との温度差が大きいほど大きくなる。また、複数の熱電変換素子１１は、互いに直列に接続されている。
For example, as shown in FIG. 1, the thermoelectric conversion device 1 according to the present embodiment is installed on the wall Wa10 so as to be exposed to the outside of the wall Wa10 of the building. As shown in FIG. 2A, the thermoelectric conversion device 1 includes a plurality of thermoelectric conversion elements 11, a first heat transfer member 12, a second heat transfer member 13, and a heat insulating member 14. Further, the plurality of thermoelectric conversion elements 11 are arranged between the first heat transfer member 12 and the second heat transfer member 13. Each of the plurality of thermoelectric conversion elements 11 is a so-called π-type thermoelectric conversion element or a laminated thermoelectric conversion element, and is thermally coupled to the first heat transfer member 12 and the second heat transfer member 13. And a portion bonded to. Then, the plurality of thermoelectric conversion elements 11 respectively respond to the temperature difference between the temperature of the portion thermally coupled to the first heat transfer member 12 and the temperature of the portion thermally coupled to the second heat transfer member 13. Generate electricity. The larger the temperature difference between the temperature of the portion thermally coupled to the first heat transfer member 12 and the temperature of the portion thermally coupled to the second heat transfer member 13, the greater the power generation amount of each of the plurality of thermoelectric conversion elements 11. growing. Further, the plurality of thermoelectric conversion elements 11 are connected in series with each other.
第１伝熱部材１２および第２伝熱部材１３は、例えば金属から板状に形成されたものである。ここで、第１伝熱部材１２は、熱電変換装置１の第１部位に相当し、第２伝熱部材１３は、熱電変換装置１の第２部位に相当する。また、第１伝熱部材１２の熱伝導率は、第２伝熱部材１３の熱伝導率よりも高い。例えば第２伝熱部材１３が鉄（熱伝導率：７２乃至８０．４Ｗ／Ｋ／ｍ）から形成されているとする。この場合、第１伝熱部材１２は、例えば銅（熱伝導率：３８６乃至４０２Ｗ／Ｋ／ｍ）から形成されていてもよい。更に、第１伝熱部材１２の少なくとも第２伝熱部材１３側とは反対側の表面１２ａの放射率が、第２伝熱部材１３の表面の放射率よりも高い。例えば第１伝熱部材１２の表面１２ａには、黒色の塗料が塗布されていてもよい。
The first heat transfer member 12 and the second heat transfer member 13 are formed of, for example, metal into a plate shape. Here, the first heat transfer member 12 corresponds to the first portion of the thermoelectric conversion device 1, and the second heat transfer member 13 corresponds to the second portion of the thermoelectric conversion device 1. The thermal conductivity of the first heat transfer member 12 is higher than the thermal conductivity of the second heat transfer member 13. For example, it is assumed that the second heat transfer member 13 is made of iron (heat conductivity: 72 to 80.4 W/K/m). In this case, the first heat transfer member 12 may be formed of, for example, copper (heat conductivity: 386 to 402 W/K/m). Furthermore, the emissivity of at least the surface 12a of the first heat transfer member 12 opposite to the second heat transfer member 13 side is higher than the emissivity of the surface of the second heat transfer member 13. For example, the surface 12a of the first heat transfer member 12 may be coated with black paint.
断熱部材１４は、第１伝熱部材１２と第２伝熱部材１３との間に配置されている。断熱部材１４は、例えば図２Ｂに示すように、複数（図２Ｂでは１２個）の熱電変換素子１１それぞれを囲繞するように配置されている。断熱部材１４は、発泡系断熱材、繊維系断熱材等から形成されている。発泡系断熱材としては、例えばポリスチレンフォーム、ポリウレタンフォーム、フェノールフォーム等が挙げられる。また、繊維系断熱材としては、グラスウール、ロックウール、セルロースファイバ、羊毛等が挙げられる。
The heat insulating member 14 is arranged between the first heat transfer member 12 and the second heat transfer member 13. As shown in FIG. 2B, for example, the heat insulating member 14 is arranged so as to surround each of the plurality (12 in FIG. 2B) of thermoelectric conversion elements 11. The heat insulating member 14 is formed of a foam heat insulating material, a fiber heat insulating material, or the like. Examples of the foam heat insulating material include polystyrene foam, polyurethane foam, and phenol foam. Further, examples of the fiber-based heat insulating material include glass wool, rock wool, cellulose fiber, and wool.
次に、本実施の形態に係る熱電変換装置１の建物の壁Ｗａ１０への設置方法について図３を参照しながら説明する。壁Ｗａ１０は、図３に示すように、外側壁Ｗａ１と、外側壁Ｗａ１の厚さ方向において外側壁Ｗａ１と隣り合うように配置された内側壁Ｗａ２と、を有する。ここで、外側壁Ｗａ１、内側壁Ｗａ２は、それぞれ、第１造営材、第２造営材に相当する。また、外側壁Ｗａ１と内側壁Ｗａ２との間には、空隙Ｓ１が形成されている。そして、外側壁Ｗａ１における熱電変換装置１が設置される箇所には、外側壁Ｗａ１を厚さ方向に貫通する開口部Ｈｏ１が穿設されている。また、内側壁Ｗａ２は、本体部Ｗａ２２と、本体部Ｗａ２２における開口部Ｈｏ１に対向する部位に配設され外側壁Ｗａ１に近づく方向へ突出した突台部Ｗａ２１と、突台部Ｗａ２１の外側壁Ｗａ１側に形成された取付面Ｗａ２１ａとを有する。外側壁Ｗａ１と内側壁Ｗａ２の本体部Ｗａ２２は、例えばコンクリートから形成され、内側壁Ｗａ２の突台部Ｗａ２１は、例えばモルタルから形成されている。
Next, a method of installing the thermoelectric conversion device 1 according to the present embodiment on the wall Wa10 of the building will be described with reference to FIG. As shown in FIG. 3, the wall Wa10 has an outer wall Wa1 and an inner side wall Wa2 arranged to be adjacent to the outer wall Wa1 in the thickness direction of the outer wall Wa1. Here, the outer side wall Wa1 and the inner side wall Wa2 correspond to a first construction material and a second construction material, respectively. A space S1 is formed between the outer wall Wa1 and the inner wall Wa2. An opening Ho1 penetrating the outer wall Wa1 in the thickness direction is formed in the outer wall Wa1 at a location where the thermoelectric conversion device 1 is installed. The inner side wall Wa2 includes a main body Wa22, a projecting pedestal Wa21 disposed in a portion of the main body Wa22 facing the opening Ho1, and projecting toward the outer wall Wa1. And a mounting surface Wa21a formed on the side. The main body portion Wa22 of the outer side wall Wa1 and the inner side wall Wa2 is made of, for example, concrete, and the protrusion part Wa21 of the inner side wall Wa2 is made of, for example, mortar.
壁Ｗａ１０に熱電変換装置１を設置する際、まず、突台部Ｗａ２１の取付面Ｗａ２１ａにエポキシ樹脂を含む接着剤（図示せず）を塗布する。なお、接着剤としては、例えばエポキシ樹脂よりも熱伝導率の高い金属を含むものであるものが、内側壁Ｗａ２から第２伝熱部材１３への伝熱性向上の観点から好ましい。次に、熱電変換装置１の第２伝熱部材１３を、接着剤により突台部Ｗａ２１に接着させることにより、熱電変換装置１を内側壁Ｗａ２に固定する。このように、第２伝熱部材１３が第２伝熱部材１３に比べて熱容量の大きい内側壁Ｗａ２に固定されていることにより、第２伝熱部材１３の温度が、内側壁Ｗａ２の温度と同じ温度で安定的に維持される。また、熱電変換装置１が、内側壁Ｗａ２の突台部Ｗａ２１に固定された状態で、外側壁Ｗａ１との間に空隙Ｓ２が形成されている。この空隙Ｓ２と熱電変換装置１の断熱部材１４とから、外側壁Ｗａ１から熱電変換装置１の第２伝熱部材１３への熱の伝達を遮蔽する断熱部が構成されている。これにより、外側壁Ｗａ１から第２伝熱部材１３への伝熱が抑制されている。
When installing the thermoelectric conversion device 1 on the wall Wa10, first, an adhesive (not shown) containing an epoxy resin is applied to the mounting surface Wa21a of the protrusion Wa21. In addition, as the adhesive, for example, an adhesive containing a metal having a higher thermal conductivity than the epoxy resin is preferable from the viewpoint of improving the heat transfer property from the inner wall Wa2 to the second heat transfer member 13. Next, the thermoelectric conversion device 1 is fixed to the inner wall Wa2 by adhering the second heat transfer member 13 of the thermoelectric conversion device 1 to the protrusion Wa21 with an adhesive. As described above, since the second heat transfer member 13 is fixed to the inner wall Wa2 having a larger heat capacity than the second heat transfer member 13, the temperature of the second heat transfer member 13 is equal to the temperature of the inner wall Wa2. Stable at the same temperature. Further, a gap S2 is formed between the thermoelectric conversion device 1 and the outer wall Wa1 in a state where the thermoelectric conversion device 1 is fixed to the protruding portion Wa21 of the inner wall Wa2. The space S2 and the heat insulating member 14 of the thermoelectric conversion device 1 constitute a heat insulating portion that shields heat transfer from the outer wall Wa1 to the second heat transfer member 13 of the thermoelectric conversion device 1. Thereby, heat transfer from the outer wall Wa1 to the second heat transfer member 13 is suppressed.
次に、本実施の形態に係る熱電変換装置１の設置方法で設置された熱電変換装置１の発電特性について、比較例に係る熱電変換装置１の設置方法で設置された場合と比較しながら説明する。比較例に係る熱電変換装置１の設置方法では、例えば図４に示すような壁Ｗａ９０に熱電変換装置１が設置される。なお、図４において実施の形態と同様の構成については図３と同一の符号を付している。壁Ｗａ９０は、外側壁Ｗａ１と内側壁Ｗａ９とを有し、内側壁Ｗａ９には突台部が設けられていない点が実施の形態に係る壁Ｗａ１０と相違する。熱電変換装置１は、その第２伝熱部材１３が内側壁Ｗａ９から距離を離した状態で、壁Ｗａ９０に固定されている。ここで、第２伝熱部材１３と内側壁Ｗａ９との間の距離Ｗ９は、例えば１０乃至２０ｃｍに設定されている。比較例に係る設置方法を採用した場合、熱電変換装置１の第２伝熱部材１３は、第２伝熱部材１３と内側壁Ｗａ９との間を流動する空気の自然対流により冷却されることになる。
Next, the power generation characteristics of the thermoelectric conversion device 1 installed by the installation method of the thermoelectric conversion device 1 according to the present embodiment will be described in comparison with the case of installation by the installation method of the thermoelectric conversion device 1 according to the comparative example. To do. In the installation method of the thermoelectric conversion device 1 according to the comparative example, the thermoelectric conversion device 1 is installed on the wall Wa90 as shown in FIG. 4, for example. In FIG. 4, the same components as those in the embodiment are designated by the same reference numerals as those in FIG. The wall Wa90 has an outer side wall Wa1 and an inner side wall Wa9, and differs from the wall Wa10 according to the embodiment in that the inner side wall Wa9 is not provided with a protrusion. The thermoelectric conversion device 1 is fixed to the wall Wa90 in a state in which the second heat transfer member 13 is separated from the inner wall Wa9. Here, the distance W9 between the second heat transfer member 13 and the inner wall Wa9 is set to, for example, 10 to 20 cm. When the installation method according to the comparative example is adopted, the second heat transfer member 13 of the thermoelectric conversion device 1 is cooled by natural convection of the air flowing between the second heat transfer member 13 and the inner side wall Wa9. Become.
ここで、本実施の形態に係る設置方法により熱電変換装置１を壁Ｗａ１０に設置した場合と比較例に係る設置方法により熱電変換装置１を壁Ｗａ９０に設置した場合とで発電量を計測した結果を表１および表２に示す。ここで、熱電変換装置１を、東向きの壁Ｗａ１０、Ｗａ９０と、南向きの壁Ｗａ１０、Ｗａ９０とに設置し、２０１８年１１月から２０１８年１２月の間の１ヶ月間における熱電変換装置１の発電量を計測した。また、熱電変換装置１として、例えば第１伝熱部材１２の表面１２ａの９０％以上に黒色の塗料が塗布されたものを採用した。表１は、東向きの壁Ｗａ１０、Ｗａ９０に熱電変換装置１を設置した場合の結果を示し、表２は、南向きの壁Ｗａ１０、Ｗａ９０に熱電変換装置１を設置した場合の結果を示す。
Here, the result of measuring the power generation amount when the thermoelectric conversion device 1 is installed on the wall Wa10 by the installation method according to the present embodiment and when the thermoelectric conversion device 1 is installed on the wall Wa90 by the installation method according to the comparative example. Are shown in Tables 1 and 2. Here, the thermoelectric conversion device 1 is installed on the walls Wa10 and Wa90 facing east and the walls Wa10 and Wa90 facing south, and the thermoelectric conversion device 1 for one month from November 2018 to December 2018 is installed. Was measured. As the thermoelectric conversion device 1, for example, a device in which 90% or more of the surface 12a of the first heat transfer member 12 is coated with black paint is adopted. Table 1 shows the results when the thermoelectric conversion device 1 was installed on the walls Wa10 and Wa90 facing east, and Table 2 shows the results when the thermoelectric conversion device 1 was installed on the walls Wa10 and Wa90 facing south.
表１に示すように、東向きの壁Ｗａ１０、Ｗａ９０に熱電変換装置１を設置した場合、実施の形態に係る設置方法を採用した場合のほうが比較例に係る設置方法を採用した場合に比べて発電量が１５．８％程度増加していることが判る。また、表２に示すように、南向きの壁Ｗａ１０、Ｗａ９０に熱電変換装置１を設置した場合、実施の形態に係る設置方法を採用した場合のほうが比較例に係る設置方法を採用した場合に比べて発電量が１８．１％程度増加していることが判る。この結果について以下のように考察される。比較例に係る設置方法を採用した場合、第２伝熱部材１３が第２伝熱部材１３と内側壁Ｗａ９との間を流動する空気の自然対流により冷却されるものであるため、第２伝熱部材１３の温度は内側壁Ｗａ９の温度よりも高くなり易い。これに対して、実施の形態に係る設置方法を採用した場合、前述のように、第２伝熱部材１３の温度が、内側壁Ｗａ２の温度と同じ温度で安定的に維持される。このため、実施の形態に係る設置方法を採用した場合のほうが、比較例に係る設置方法を採用した場合に比べて、第１伝熱部材１２の温度と第２伝熱部材１３の温度との温度差が大きくなり、熱電変換装置１の発電量も大きくなると考えられる。
As shown in Table 1, when the thermoelectric conversion device 1 is installed on the walls Wa10 and Wa90 facing east, the case where the installation method according to the embodiment is adopted is better than the case where the installation method according to the comparative example is adopted. It can be seen that the amount of power generation has increased by about 15.8%. Further, as shown in Table 2, when the thermoelectric conversion device 1 is installed on the south facing walls Wa10 and Wa90, when the installation method according to the embodiment is adopted, the installation method according to the comparative example is adopted. In comparison, it can be seen that the amount of power generation has increased by about 18.1%. The results are considered as follows. When the installation method according to the comparative example is adopted, the second heat transfer member 13 is cooled by natural convection of the air flowing between the second heat transfer member 13 and the inner side wall Wa9. The temperature of the heat member 13 tends to be higher than the temperature of the inner wall Wa9. On the other hand, when the installation method according to the embodiment is adopted, as described above, the temperature of the second heat transfer member 13 is stably maintained at the same temperature as the temperature of the inner wall Wa2. Therefore, the temperature of the first heat transfer member 12 and the temperature of the second heat transfer member 13 in the case where the installation method according to the embodiment is adopted are higher than those in the case where the installation method according to the comparative example is adopted. It is considered that the temperature difference increases and the amount of power generation of the thermoelectric conversion device 1 also increases.
以上説明したように、本実施の形態に係る熱電変換装置１の設置方法によれば、外側壁Ｗａ１に穿設された開口部Ｈｏ１から第１伝熱部材１２が外側壁Ｗａ１における内側壁Ｗａ２側とは反対側へ露出し且つ第２伝熱部材１３が内側壁Ｗａ２の突台部Ｗａ２１に接触した状態で熱電変換装置１を建物の壁Ｗａ１０に設置する。これにより、例えば第２伝熱部材１３が内側壁Ｗａ９から距離を離した状態で熱電変換装置１を建物の壁Ｗａ９０に設置した場合に比べて、第１伝熱部材１２の温度と第２伝熱部材１３の温度との温度差を大きくすることができる。従って、建物の壁に設置された熱電変換装置１の発電量を向上させることができる。
As described above, according to the installation method of the thermoelectric conversion device 1 according to the present embodiment, the first heat transfer member 12 extends from the opening Ho1 formed in the outer wall Wa1 to the inner wall Wa2 side of the outer wall Wa1. The thermoelectric conversion device 1 is installed on the wall Wa10 of the building while being exposed to the side opposite to and the second heat transfer member 13 is in contact with the projecting portion Wa21 of the inner wall Wa2. Thereby, as compared with the case where the thermoelectric conversion device 1 is installed on the wall Wa90 of the building in a state where the second heat transfer member 13 is separated from the inner wall Wa9, for example, the temperature of the first heat transfer member 12 and the second heat transfer member 12 are increased. The temperature difference from the temperature of the heat member 13 can be increased. Therefore, the power generation amount of the thermoelectric conversion device 1 installed on the wall of the building can be improved.
また、本実施の形態に係る熱電変換装置１の設置方法では、熱電変換装置１を、外側壁Ｗａ１と内側壁Ｗａ２の本体部Ｗａ２２との間に空隙Ｓ１が形成された壁Ｗａ１０に設置する。これにより、外側壁Ｗａ１から内側壁Ｗａ２への伝熱を抑制できるので、第１伝熱部材１２の温度と、内側壁Ｗａ２の突台部Ｗａ２１に固定された第２伝熱部材１３の温度との温度差を大きくできる。従って、第１伝熱部材１２の温度と第２伝熱部材１３の温度との温度差を大きくできる分、熱電変換装置１の発電量を増加させることができる。
In addition, in the installation method of the thermoelectric conversion device 1 according to the present embodiment, the thermoelectric conversion device 1 is installed on the wall Wa10 in which the space S1 is formed between the outer wall Wa1 and the main body Wa22 of the inner wall Wa2. Thereby, heat transfer from the outer wall Wa1 to the inner wall Wa2 can be suppressed, so that the temperature of the first heat transfer member 12 and the temperature of the second heat transfer member 13 fixed to the protruding portion Wa21 of the inner wall Wa2 can be suppressed. The temperature difference can be increased. Therefore, as the temperature difference between the temperature of the first heat transfer member 12 and the temperature of the second heat transfer member 13 can be increased, the power generation amount of the thermoelectric conversion device 1 can be increased.
更に、本実施の形態に係る熱電変換装置１の設置方法では、熱電変換装置１の周部と外側壁Ｗａ１との間に、空隙Ｓ２が形成されるように熱電変換装置１が内側壁Ｗａ２の突台部Ｗａ２１に固定される。また、熱電変換装置１が、複数の熱電変換素子１１それぞれを囲繞するように配置された断熱部材１４を備える。これにより、外側壁Ｗａ１から第２伝熱部材１３への伝熱が抑制され、第２伝熱部材１３の温度変動が抑制されるので、熱電変換装置１の発電量を安定させることができる。
Further, in the installation method of the thermoelectric conversion device 1 according to the present embodiment, the thermoelectric conversion device 1 has the inner wall Wa2 so that the space S2 is formed between the peripheral portion of the thermoelectric conversion device 1 and the outer wall Wa1. It is fixed to the stand portion Wa21. In addition, the thermoelectric conversion device 1 includes a heat insulating member 14 arranged so as to surround each of the plurality of thermoelectric conversion elements 11. Thereby, the heat transfer from the outer wall Wa1 to the second heat transfer member 13 is suppressed, and the temperature fluctuation of the second heat transfer member 13 is suppressed, so that the power generation amount of the thermoelectric conversion device 1 can be stabilized.
また、本実施の形態に係る第１伝熱部材１２の熱伝導率は、第２伝熱部材１３の熱伝導率よりも高い。更に、第１伝熱部材１２における外側壁Ｗａ１に穿設された開口部Ｈｏ１から露出した部分の放射率は、第２伝熱部材１３の放射率よりも高い。これにより、太陽からの放射エネルギを効率良く熱電変換素子１１へ伝達させることができるとともに、第２伝熱部材１３の温度変動を抑制することができる。従って、熱電変換装置１の発電量を増加させ且つ安定させることができる。
Further, the thermal conductivity of the first heat transfer member 12 according to the present embodiment is higher than the thermal conductivity of the second heat transfer member 13. Furthermore, the emissivity of the portion of the first heat transfer member 12 exposed from the opening Ho1 formed in the outer wall Wa1 is higher than the emissivity of the second heat transfer member 13. Thereby, the radiant energy from the sun can be efficiently transmitted to the thermoelectric conversion element 11, and the temperature fluctuation of the second heat transfer member 13 can be suppressed. Therefore, the power generation amount of the thermoelectric conversion device 1 can be increased and stabilized.
以上、本発明の実施の形態について説明したが、本発明は前述の実施の形態の構成に限定されるものではない。例えば図５に示すように、複数（図５では８つ）の熱電変換装置１を壁Ｗａ２０に二次元に並べて設置してもよい。この場合、図６に示すように、壁Ｗａ２０の外側壁Ｗａ２０１として、その複数の熱電変換装置１が設置される箇所に、外側壁Ｗａ２０１を厚さ方向に貫通する開口部Ｈｏ２が穿設されたものを採用すればよい。そして、壁Ｗａ２０の内側壁Ｗａ２０２として、その開口部Ｈｏ２に対向する部位に、外側壁Ｗａ２０１に近づく方向へ突出した突台部Ｗａ２２１が配設されたものを採用すればよい。
Although the embodiments of the present invention have been described above, the present invention is not limited to the configurations of the above-described embodiments. For example, as shown in FIG. 5, a plurality (eight in FIG. 5) of thermoelectric conversion devices 1 may be arranged two-dimensionally on the wall Wa20. In this case, as shown in FIG. 6, as the outer wall Wa201 of the wall Wa20, an opening Ho2 penetrating the outer wall Wa201 in the thickness direction is formed at a position where the plurality of thermoelectric conversion devices 1 are installed. You can adopt one. Then, as the inner wall Wa202 of the wall Wa20, the one in which the protruding portion Wa221 that protrudes in the direction approaching the outer wall Wa201 is arranged at the portion facing the opening Ho2 may be adopted.
