　特許文献１には、輻射型室内機を備えた空気調和装置が開示されている。輻射型室内機は、鉛直方向に立設する一対の縦フレームと、一対の縦フレームの間に配置される発熱体とを備える。発熱体は、冷媒配管と、冷媒配管で伝熱する伝熱部材とを備える。空気調和装置の暖房運転時には、圧縮機で圧縮された高圧の冷媒が、輻射型室内機の冷媒配管で放熱する。この結果、輻射型室内機の伝熱部材から室内空間へ輻射熱が放出される。 Patent Document 1 discloses an air conditioner provided with a radiation type indoor unit. The radiation type indoor unit includes a pair of vertical frames erected in the vertical direction and a heating element disposed between the pair of vertical frames. The heat generating body includes a refrigerant pipe and a heat transfer member which transfers heat by the refrigerant pipe. During the heating operation of the air conditioner, the high-pressure refrigerant compressed by the compressor dissipates heat in the refrigerant piping of the radiant indoor unit. As a result, radiant heat is released from the heat transfer member of the radiant indoor unit to the indoor space.

　熱交換エレメント（70）は、上下に縦長の平板状の板部（71）と、該板部（71）の前面（71a）に設けられる複数の突起部（前側突起部（72））と、該板部（71）の後面（71b）に設けられる複数の突起部（後側突起部（73））と、板部（71）の幅方向の両端にそれぞれ設けられる連結部（74）とを備えている。本実施形態のパネル本体（60）では、複数の板部（71）が幅方向に連結されることで、１つの平板状の平板部（63）が構成される。つまり、パネル本体（60）の平板部（63）は、複数の板部（71）に分割可能に構成される。 The heat exchange element (70) includes a vertically long flat plate (71) and a plurality of protrusions (front protrusions (72)) provided on the front surface (71a) of the plate (71). A plurality of projections (rear projections (73)) provided on the rear surface (71b) of the plate (71), and connecting portions (74) provided on both ends in the width direction of the plate (71) Have. In the panel main body (60) of the present embodiment, a plurality of plate portions (71) are connected in the width direction to form one flat plate portion (63). That is, the flat plate portion (63) of the panel body (60) is configured to be divisible into a plurality of plate portions (71).
　〈板部／平板部の構成〉
　板部（71）（平板部（63））には、複数の挿通孔（64）が上下方向に貫通して形成される。挿通孔（64）は、平板部（63）の幅方向に等間隔を置いて配列される。挿通孔（64）には、伝熱管（53）の直管部（54）が挿通される。挿通孔（64）の周囲には、直管部（54）の外周面と面接触する筒状の周壁（65）が形成される。これにより、伝熱管（53）の内部を流れる冷媒と伝熱部材（70A）との間で熱が伝導する。 <Structure of plate portion / flat plate portion>
A plurality of insertion holes (64) are formed through the plate portion (71) (flat plate portion (63)) in the vertical direction. The insertion holes (64) are arranged at equal intervals in the width direction of the flat plate portion (63). The straight pipe portion (54) of the heat transfer pipe (53) is inserted into the insertion hole (64). A cylindrical peripheral wall (65) in surface contact with the outer peripheral surface of the straight pipe portion (54) is formed around the insertion hole (64). Thereby, heat is conducted between the refrigerant flowing in the heat transfer tube (53) and the heat transfer member (70A).
　本実施形態では、複数の挿通孔（64）のうちの一部には、伝熱管（53）が挿通されていない（例えば図５を参照）。つまり、輻射パネル（40）では、挿通孔（64）の総数よりも直管部（54）の総数が少ない。これにより、伝熱管（53）の全長を短くでき、輻射パネル（40）の内部を流れる冷媒の圧力損失を低減できる。なお、全ての挿通孔（64）に伝熱管（53）の直管部（54）を挿通する構成としてもよい。 In the present embodiment, the heat transfer pipe (53) is not inserted into a part of the plurality of insertion holes (64) (see, for example, FIG. 5). That is, in the radiation panel (40), the total number of straight pipe portions (54) is smaller than the total number of insertion holes (64). Thus, the total length of the heat transfer tube (53) can be shortened, and the pressure loss of the refrigerant flowing in the radiation panel (40) can be reduced. The straight pipe portion (54) of the heat transfer pipe (53) may be inserted into all the insertion holes (64).
　板部（71）（平板部（63））には、締結部材（例えばタッピンネジ、図示省略）が締結可能な複数の締結孔（66）が形成される。各締結孔（66）は、隣り合う周壁（65）の間にそれぞれ配置される。締結孔（66）の周囲には、横断面が略Ｃ字状の締結壁（67）が形成される。つまり、締結壁（67）は、環状の壁の一部が切除された形状をしている。このように環状の締結壁（67）を切除することで、締結部材に対する締結孔（66）の寸法公差を緩和できる。 A plurality of fastening holes (66) to which fastening members (for example, tapping screws, not shown) can be fastened are formed in the plate portion (71) (flat plate portion (63)). Each fastening hole (66) is disposed between adjacent peripheral walls (65). A fastening wall (67) having a substantially C-shaped cross section is formed around the fastening hole (66). That is, the fastening wall (67) has a shape in which a part of the annular wall is cut away. By removing the annular fastening wall (67) in this manner, dimensional tolerances of the fastening hole (66) with respect to the fastening member can be relaxed.
　本実施形態の締結壁（67）は、対応する切除部（67a）が板部（71）の幅方向を向いている。熱交換エレメント（70）では、一対の締結壁（67）の断面形状が、板部（71）の幅方向の中間部を挟んで対称となっている（図４及び図５を参照）。より詳細には、一対の締結壁（67）は、対応する切除部（67a）が板部（71）の幅方向外方を向いている。 In the fastening wall (67) of the present embodiment, the corresponding cut-out portion (67a) faces in the width direction of the plate portion (71). In the heat exchange element (70), the cross-sectional shapes of the pair of fastening walls (67) are symmetrical with respect to the widthwise intermediate portion of the plate portion (71) (see FIGS. 4 and 5). More specifically, in the pair of fastening walls (67), the corresponding cutouts (67a) face outward in the width direction of the plate (71).
　板部（71）（平板部（63））には、複数の肉抜き部（板部側肉抜き部（68））が形成されている。板部側肉抜き部（68）は、熱交換エレメント（70）の長手方向（上下方向）の両端に亘るように、該熱交換エレメント（70）を貫通している。板部側肉抜き部（68）は、連結部（74）と周壁（65）との間、及び周壁（65）と締結壁（67）のと間に形成される。これにより、熱交換エレメント（70）の軽量化、ひいてはパネル本体（60）の軽量化が図られる。 A plurality of lightening parts (plate part side lightening parts (68)) are formed in the plate part (71) (flat part (63)). The plate portion side lightening portion (68) penetrates the heat exchange element (70) so as to extend to both ends in the longitudinal direction (vertical direction) of the heat exchange element (70). The plate-portion-side lightening portion (68) is formed between the connecting portion (74) and the peripheral wall (65), and between the peripheral wall (65) and the fastening wall (67). Thereby, the weight reduction of the heat exchange element (70), and hence the weight reduction of the panel body (60) can be achieved.
　〈突起部〉
　板部（71）（平板部（63））の前面（71a）には、複数の前側突起部（72）が形成される。平板部（63）ないし板部（71）の後面（71b）には、複数の後側突起部（73）が形成される。つまり、熱交換エレメント（70）では、その厚さ方向の両側の面（71a,71b）にそれぞれ複数（２つ以上）の突起部（72,73）が設けられる。本実施形態の輻射パネル（40）では、前側突起部（72）の総数と、後側突起部（73）の総数とが等しい。 <protrusion>
A plurality of front projections (72) are formed on the front surface (71a) of the plate portion (71) (flat plate portion (63)). A plurality of rear side projections (73) are formed on the flat surface (63) to the rear surface (71b) of the plate (71). That is, in the heat exchange element (70), a plurality of (two or more) protrusions (72, 73) are provided on the surfaces (71a, 71b) on both sides in the thickness direction. In the radiation panel (40) of the present embodiment, the total number of the front protrusions (72) and the total number of the rear protrusions (73) are equal.
　各突起部（72,73）は、横断面が矩形形状となる略板状に形成される。各突起部（72,73）は、上下方向に延びている。前側突起部（72）は、伝熱管（53）ないし挿通孔（64）と平板部（63）の厚さ方向に重なる位置に設けられる。後側突起部（73）は、伝熱管（53）ないし挿通孔（64）と平板部（63）の厚さ方向に重なる位置に設けられる。つまり、本実施形態では、前側突起部（72）と後側突起部（73）とが平板部（63）の厚さ方向に重なっている。この構成により、前側突起部（72）、後側突起部（73）、及び板部（71）が、全体として略十字形状をなしている。 Each protrusion (72, 73) is formed in a substantially plate shape whose cross section is rectangular. Each protrusion (72, 73) extends in the vertical direction. The front projection (72) is provided at a position where the heat transfer tube (53) or the insertion hole (64) overlaps the flat plate (63) in the thickness direction. The rear protrusion (73) is provided at a position where the heat transfer tube (53) or the insertion hole (64) and the flat portion (63) overlap in the thickness direction. That is, in the present embodiment, the front protrusion (72) and the rear protrusion (73) overlap in the thickness direction of the flat portion (63). With this configuration, the front protrusion (72), the rear protrusion (73), and the plate (71) have a substantially cross shape as a whole.
　前側突起部（72）及び後側突起部（73）には、それぞれ肉抜き部（突起側肉抜き部（69））が形成される。突起側肉抜き部（69）は、熱交換エレメント（70）の長手方向（上下方向）の両端に亘るように、該熱交換エレメント（70）を貫通している。突起側肉抜き部（69）の横断面形状は、各突起部（72,73）に対応する略矩形状に形成される。これにより、熱交換エレメント（70）の軽量化、ひいてはパネル本体（60）の軽量化が図られる。 Lightening portions (protrusion-side lightening portions (69)) are formed in the front protrusion (72) and the rear protrusion (73), respectively. The protrusion-side lightening part (69) penetrates the heat exchange element (70) so as to extend to both ends in the longitudinal direction (vertical direction) of the heat exchange element (70). The cross-sectional shape of the protrusion-side thinned portion (69) is formed in a substantially rectangular shape corresponding to each protrusion (72, 73). Thereby, the weight reduction of the heat exchange element (70), and hence the weight reduction of the panel body (60) can be achieved.
　〈連結部〉
　図４及び図５に示すように、板部（71）の幅方向（左右方向）の両端には、連結部（74）がそれぞれ設けられる。一対の連結部（74）は、板部（71）の側端から側方外方へ突出する突片部（74a）と、該突片部（74a）の先端から板部（71）の厚さ方向内方へ屈曲する爪部（74b）とを有する。突片部（74a）の厚みは、板部（71）の厚みよりも小さい。突片部（74a）は、板部（71）の前面（71a）及び後面（71b）のいずれか一方の面と略面一となる。このように連結部（74）を設けることで、板部（71）の側端と爪部（74b）との間に、爪部（74b）が係合する係合溝（75）が形成される。つまり、係合溝（75）の横断面形状は、爪部（74b）の横断面形状と概ね等しい。本実施形態の熱交換エレメント（70）では、一対の連結部（74）の断面形状が、板部（71）の幅方向の中間部を挟んで対称となっている。 <Connection section>
As shown in FIGS. 4 and 5, connecting portions (74) are respectively provided at both ends in the width direction (left and right direction) of the plate portion (71). The pair of connecting portions (74) is a projecting piece (74a) projecting laterally outward from the side end of the plate (71), and a thickness of the plate (71) from the tip of the projecting piece (74a) And a claw (74b) bent inward in the longitudinal direction. The thickness of the projecting portion (74a) is smaller than the thickness of the plate portion (71). The projecting portion (74a) is substantially flush with one of the front surface (71a) and the rear surface (71b) of the plate portion (71). By providing the connecting portion (74) in this manner, an engagement groove (75) with which the claw portion (74b) is engaged is formed between the side end of the plate portion (71) and the claw portion (74b). Ru. That is, the cross-sectional shape of the engagement groove (75) is substantially equal to the cross-sectional shape of the claw portion (74b). In the heat exchange element (70) of the present embodiment, the cross-sectional shapes of the pair of connection portions (74) are symmetrical with respect to the widthwise intermediate portion of the plate portion (71).
　パネル本体（60）では、各熱交換エレメント（70）の向きが、交互に逆向きとなるように、複数の熱交換エレメント（70）が幅方向に配列される。パネル本体（60）では、隣り合う２つの熱交換エレメント（70）のうちの一方の熱交換エレメント（70）の爪部（74b）が、他方の熱交換エレメント（70）の係合溝（75）に係合する。これにより、隣り合う熱交換エレメント（70）が互いに連結される（図３を参照）。 In the panel body (60), the plurality of heat exchange elements (70) are arranged in the width direction such that the directions of the respective heat exchange elements (70) are alternately reversed.

Each is formed. The groove (80) extends in the vertical direction. The cross-sectional shape of the bottom surface of the groove (80) of the present embodiment is formed in a substantially V-shape. The cross-sectional shape of the groove (80) is substantially the same over the top and bottom.
　熱交換エレメント（70）の表面で結露水が発生した場合、この結露水を溝（80）の内部に捕捉できる。更に、溝（80）は、上下方向に延びているため、捕捉した結露水を、溝（80）を通じて下方へ案内できる。 When dew condensation water is generated on the surface of the heat exchange element (70), the dew condensation water can be trapped inside the groove (80). Further, since the groove (80) extends in the vertical direction, the captured condensed water can be guided downward through the groove (80).

In the present embodiment, the intervals P1 and P2 are set to about 36.6 mm.
　パネル本体（60）では、前側突起部（72）の突出高さＬ１が、平板部（63）（板部（71））の厚さＤ以上である。パネル本体（60）では、後側突起部（73）の突出高さＬ２が、平板部（63）（板部（71））の厚さＤ以上である。本実施形態では、突出高さＬ１と突出高さＬ２とが等しい。本実施形態では、突出高さＬ１及び突出高さＬ２が約１６．９ｍｍに設定され、厚さＤが約１０．１ｍｍに設定される。 In the panel main body (60), the projection height L1 of the front protrusion (72) is equal to or greater than the thickness D of the flat plate (63) (plate (71)).

　－実施形態の効果－
　本実施形態では、複数の前側突起部（72）の間隔Ｐ１が１００ｍｍ以下である。間隔Ｐ１が大きすぎると、在室者（ユーザやメンテナンス業者等）の手の全体が平板部（63）の表面に面接触し、在室者が過剰に熱く感じる可能性がある。これに対し、間隔Ｐ１を、手の一般的な幅寸法といえる１００ｍｍ以下とすると、隣り合う前側突起部（72）の間に手が入りにくくなり、手の全体が平板部（63）の前面（71a）に面接触することを抑制できる。同様に、複数の後側突起部（73）の間隔Ｐ２を１００ｍｍ以下とすることで、隣り合う後側突起部（73）の間に手が入りにくくなり、手の全体が平板部（63）の前面（71a）に面接触することを抑制できる。 -Effect of the embodiment-
In the present embodiment, the distance P1 between the plurality of front protrusions (72) is 100 mm or less. If the interval P1 is too large, the entire hands of the occupant (user, maintenance worker, etc.) may come into surface contact with the surface of the flat portion (63), and the occupant may feel excessively hot. On the other hand, when the distance P1 is 100 mm or less which can be said to be a general width dimension of the hand, it becomes difficult for the hand to enter between adjacent front protrusions (72), and the entire hand is the front surface of the flat portion (63) Surface contact with (71a) can be suppressed. Similarly, by setting the distance P2 of the plurality of rear side projections (73) to 100 mm or less, it becomes difficult for a hand to enter between adjacent rear side projections (73), and the whole hand is a flat portion (63) Surface contact with the front surface (71a) of
　平板部（63）を有する輻射パネル（40）を床面に設置することで、平板部（63）が室内の仕切りとして機能する。ここで、仮に輻射パネルの伝熱部材がルーバのような構造であると、輻射パネルの前後を貫通する複数の隙間が形成されてしまう。この場合、ユーザ等は、これらの隙間を通じて輻射パネルの反対側が見えてしまい、室内の美感が損なわれてしまう可能性がある。これに対し、本実施形態では、輻射パネル（40）の前後を完全に仕切る平板状の平板部（63）を有するため、室内の美感が損なわれることを抑制できる。 By installing the radiation panel (40) having the flat portion (63) on the floor surface, the flat portion (63) functions as a partition in the room. Here, if the heat transfer member of the radiation panel is a louver-like structure, a plurality of gaps penetrating the front and back of the radiation panel will be formed. In this case, the user or the like may see the other side of the radiation panel through these gaps, which may impair the beauty of the room. On the other hand, in the present embodiment, since the flat plate portion (63) which completely divides the front and rear of the radiation panel (40) is provided, it is possible to suppress the loss of the indoor beauty.
　平板部（63）の前面（71a）及び後面（71b）に突起部（72,73）を形成することで、伝熱部材（70A）の表面積を拡大できる。これにより、輻射パネル（40）の加熱能力や冷却能力を向上できる。 By forming the protrusions (72, 73) on the front surface (71 a) and the rear surface (71 b) of the flat plate portion (63), the surface area of the heat transfer member (70 A) can be expanded. Thereby, the heating capacity and the cooling capacity of the radiation panel (40) can be improved.
　本実施形態では、複数の前側突起部（72）の間隔Ｐ１が１５ｍｍ以上である。間隔Ｐ２が小さすぎると、在室者が前側突起部（72）の先端に触れてしまう面積が広くなり、在室者が過剰に熱く感じる可能性がある。これに対し、間隔Ｐ１を１５ｍｍ以上とすると、隣り合う前側突起部（72）の間に手の一部（例えば指）が入り込み易くなり、前側突起部（72）の先端の接触面積が小さくなる。同様に、複数の後側突起部（73）の間隔Ｐ２を１５ｍｍ以上とすることで、隣り合う後側突起部（73）の間に手の一部（例えば指）が入り込み易くなる。 In the present embodiment, the interval P1 of the plurality of front protrusions (72) is 15 mm or more. If the distance P2 is too small, the area in which the occupant touches the tip of the front projection (72) is large, and the occupant may feel excessively hot. On the other hand, when the interval P1 is 15 mm or more, a part (for example, a finger) of the hand can easily enter between the adjacent front protrusions (72), and the contact area of the tip of the front protrusions (72) decreases. . Similarly, by setting the distance P2 of the plurality of rear protrusions (73) to 15 mm or more, a part (for example, a finger) of the hand can easily enter between the adjacent rear protrusions (73).
　本実施形態では、前側突起部（72）及び後側突起部（73）が、平板部（63）の面（71a,71b）に沿って延びる凸条で構成される。これらの間隔Ｐ１及びＰ２を１００ｍｍ以下とすることで、隣り合う前側突起部（72）の間、及び隣り合う後側突起部（73）の間に手が入り込むことを抑制できる。 In the present embodiment, the front protrusion (72) and the rear protrusion (73) are formed of ridges extending along the surface (71a, 71b) of the flat portion (63). By setting the intervals P1 and P2 to 100 mm or less, it is possible to suppress the entry of a hand between adjacent front projections (72) and between adjacent rear projections (73).
　本実施形態では、前側突起部（72）及び後側突起部（73）が上下方向に延びている。このため、伝熱部材（70A）の表面で結露水が発生したとしても、この結露水を下方へ容易に導くことができる。 In the present embodiment, the front protrusion (72) and the rear protrusion (73) extend in the vertical direction. Therefore, even if dew condensation water is generated on the surface of the heat transfer member (70A), the dew condensation water can be easily led downward.
　本実施形態では、前側突起部（72）及び後側突起部（73）が板状に形成される。この結果、前側突起部（72）及び後側突起部（73）の先端に触れた手が傷つくことを確実に抑制できる。 In the present embodiment, the front protrusion (72) and the rear protrusion (73) are formed in a plate shape. As a result, it can be reliably suppressed that the hand touching the front end of the front protrusion (72) and the rear protrusion (73) is damaged.
　本実施形態では、平板部（63）の前面（71a）と後面（71b）との双方に突起部（72,73）を形成している。このため、平板部（63）の前面（71a）及び後面（71b）の双方において、手の接触面積が大きくなることを抑制できるとともに、伝熱部材（70A）の伝熱面積を拡大できる。 In the present embodiment, the protrusions (72, 73) are formed on both the front surface (71 a) and the rear surface (71 b) of the flat plate portion (63). Therefore, it is possible to suppress an increase in the contact area of the hand on both the front surface (71a) and the rear surface (71b) of the flat plate portion (63), and to expand the heat transfer area of the heat transfer member (70A).
　本実施形態では、前側突起部（72）と、後側突起部（73）とがパネル本体（60）の厚さ方向に重なっている。これにより、前側突起部（72）、後側突起部（73）、及び平板部（63）により、十字形状の横断面を形成でき、パネル本体（60）の美感を向上できる。 In the present embodiment, the front protrusion (72) and the rear protrusion (73) overlap in the thickness direction of the panel body (60). As a result, a cross-shaped cross section can be formed by the front protrusion (72), the rear protrusion (73), and the flat plate (63), and the aesthetics of the panel body (60) can be improved.
　本実施形態では、平板部（63）の内部に伝熱管（53）が挿通される挿通孔（64）を形成し、前側突起部（72）及び後側突起部（73）を挿通孔（64）と厚さ方向に重なる位置に設けている。この構造により、突起部（72,73）の基部と挿通孔（64）の周囲の周壁（65）とがオーバーラップするため、周壁（65）の肉厚を確保し易くなる。加えて、伝熱管（53）と突起部（72,73）との間の伝熱を促進できる。 In this embodiment, an insertion hole (64) through which the heat transfer pipe (53) is inserted is formed in the flat plate portion (63), and the front projection (72) and the rear projection (73) are inserted into the insertion hole (64). ) And in the thickness direction. With this structure, the base of the protrusion (72, 73) and the peripheral wall (65) around the insertion hole (64) overlap, so that the thickness of the peripheral wall (65) can be easily secured. In addition, heat transfer between the heat transfer tube (53) and the projection (72, 73) can be promoted.
　特に本実施形態では、突起部（72,73）の厚さＤ１、Ｄ２を、伝熱管（53）の直径ｄよりも大きくしているため、突起部（72,73）と周壁（65）とのオーバーラップ部分の幅を十分に確保できる。 In the present embodiment, in particular, since the thicknesses D1 and D2 of the protrusions (72, 73) are larger than the diameter d of the heat transfer tube (53), the protrusions (72, 73) and the peripheral wall (65) The width of the overlapping portion can be secured sufficiently.
　本実施形態では、前側突起部（72）の突出高さＬ１が平板部（63）の厚さＤよりも大きい。このように前側突起部（72）の突出高さＬ１を比較的大きくすると、在室者の手が平板部（63）の前面（71a）まで届くのを抑制できる。同様に、後側突起部（73）の突出高さＬ２を平板部（63）の厚さＤよりも大きくすることで、在室者の手が平板部（63）の後面（71b）まで届くのを抑制できる。 In the present embodiment, the protrusion height L1 of the front protrusion (72) is larger than the thickness D of the flat portion (63). As described above, when the protrusion height L1 of the front protrusion (72) is relatively large, the hand of the occupant can be prevented from reaching the front surface (71a) of the flat plate portion (63). Similarly, by making the protrusion height L2 of the rear side protrusion (73) larger than the thickness D of the flat portion (63), the hands of the occupant reach the rear surface (71b) of the flat portion (63). You can control the
　本実施形態では、複数の熱交換エレメント（70）を伝熱部材（70A）の幅方向に配列し、連結部（74）を介してこれらの熱交換エレメント（70）を連結する構造（分割構造）としている。仮に伝熱部材（70A）を一体構造とすると、熱歪みに起因する伝熱部材（70A）の撓み量が大きくなる。これに対し、伝熱部材（70A）をこのような分割構造とすると、熱歪むに起因する伝熱部材（70A）の撓み量を吸収・緩和できる。この結果、伝熱部材（70A）が全体として大きく撓んでしまうことを抑制できる。また、伝熱部材（70A）を複数の熱交換エレメント（70）として分割することで、伝熱部材（70A）の搬送も容易となる。 In this embodiment, a plurality of heat exchange elements (70) are arranged in the width direction of the heat transfer member (70A), and these heat exchange elements (70) are connected via the connection portion (74) (split structure ). Assuming that the heat transfer member (70A) is integrally formed, the amount of deflection of the heat transfer member (70A) due to the thermal strain becomes large. On the other hand, when the heat transfer member (70A) has such a divided structure, the amount of bending of the heat transfer member (70A) due to thermal distortion can be absorbed and reduced. As a result, it is possible to suppress that the heat transfer member (70A) is largely bent as a whole. Further, by dividing the heat transfer member (70A) as a plurality of heat exchange elements (70), the transfer of the heat transfer member (70A) is also facilitated.
　本実施形態では、熱交換エレメント（70）にそれぞれ連結部（74）を設けることで、各熱交換エレメント（70）の配列・組み立て作業を簡便に行うことができる。 In the present embodiment, by providing the connecting portions (74) in the heat exchange elements (70), the operation of arranging and assembling the heat exchange elements (70) can be easily performed.
　〈変形例１〉
　図６に示す変形例１は、伝熱部材（70A）（熱交換エレメント（70））において、複数の前側突起部（72）の総数と、複数の後側突起部（73）の総数とが異なる。具体的に、変形例１では、前側突起部（72）の総数が、後側突起部（73）の総数よりも多い。このようにすると、伝熱部材（70A）では、前面（71a）側の伝熱面積が、後面（71b）側の伝熱面積よりも大きくなる。このため、変形例１の輻射パネル（40）では、前面（71a）側の加熱能力及び冷却能力を向上できる。 Modified Example 1
In the heat transfer member (70A) (heat exchange element (70)), the modified example 1 shown in FIG. 6 has the total number of the plurality of front side protrusions (72) and the total number of the plurality of rear side protrusions (73) It is different. Specifically, in the first modification, the total number of the front protrusions (72) is larger than the total number of the rear protrusions (73). In this case, in the heat transfer member (70A), the heat transfer area on the front surface (71a) side is larger than the heat transfer area on the rear surface (71b) side. For this reason, in the radiation panel (40) of the modified example 1, the heating capacity and the cooling capacity on the front surface (71a) side can be improved.
　〈変形例２〉
　図７に示す変形例２の熱交換エレメント（70）では、その左右の連結部（74）の爪部（74b）の突出方向が互いに逆向きとなっている。この構成では、隣り合う熱交換エレメント（70）の連結部（74）の向きを気にすることなく、隣り合う熱交換エレメント（70）を連結することができる。 <Modification 2>
In the heat exchange element (70) of the second modification shown in FIG. 7, the projecting directions of the claws (74b) of the left and right connecting parts (74) are opposite to each other. In this configuration, adjacent heat exchange elements (70) can be connected without regard to the direction of the connection portion (74) of adjacent heat exchange elements (70).
