（冷暖房用輻射パネルの製造方法）
次に、本冷暖房用輻射パネル１の製造方法の一例について、図３及び図４を参照して説明する。まず、押出工程を経て製造された熱交換パイプ２を高温（例えば３０〜６０℃）の状態の図３（ａ）に示す成形型６の溝６ａに嵌め込む。成形型６には、蛇行した形状を有し、複数の熱交換パイプ２の直線部分２ａと曲線部分２ｂに対応する溝６ａが形成されている。なお、熱交換パイプ２を成形型６から取り出したときの戻り具合を考慮して、予め熱交換パイプ２の直線部分２ａに対応する溝６ａの部分を傾けてもよい。 (Manufacturing method of radiation panel for air conditioning)
Next, an example of the manufacturing method of this radiation panel 1 for cooling and heating is demonstrated with reference to FIG.3 and FIG.4. First, the heat exchange pipe 2 manufactured through the extrusion process is fitted into the groove 6a of the mold 6 shown in FIG. 3A in a high temperature (for example, 30 to 60 ° C.) state. The molding die 6 has a meandering shape and is formed with grooves 6a corresponding to the straight portions 2a and the curved portions 2b of the plurality of heat exchange pipes 2. In consideration of the return condition when the heat exchange pipe 2 is taken out from the mold 6, the portion of the groove 6a corresponding to the straight portion 2a of the heat exchange pipe 2 may be inclined in advance.

次に、熱交換パイプ２を例えば自然空冷により冷却した後、図３（ｂ）に示すように、熱交換パイプ２を成形型６から取り出す。このとき、熱交換パイプ２は、自身が有する弾性力あるいは復元力により図３（ｂ）に示すように緩やかな蛇行形状になる。   Next, after cooling the heat exchange pipe 2 by, for example, natural air cooling, the heat exchange pipe 2 is taken out from the mold 6 as shown in FIG. At this time, the heat exchange pipe 2 has a gentle meandering shape as shown in FIG. 3B due to its own elastic force or restoring force.

次に、図３（ｃ）に示すように、熱交換パイプ２の直線部分２ａと曲線部分２ｂとの境界付近を保持部材４で保持し、熱交換パイプ２の両端部に連結部２ｃを接続する。   Next, as shown in FIG. 3 (c), the vicinity of the boundary between the straight portion 2 a and the curved portion 2 b of the heat exchange pipe 2 is held by the holding member 4, and the connecting portions 2 c are connected to both ends of the heat exchange pipe 2.

次に、図４に示すように、ステージ７上で膨張黒鉛を含んで形成された膨張黒鉛シート３Ａ、３Ｂ間に熱交換パイプ２を配置し、一対の膨張黒鉛シート３Ａ、３Ｂを熱交換パイプ２とともに上方から圧縮する。この圧縮によって一対の膨張黒鉛シート３Ａ、３Ｂの接合面３ｃ、３ｄ同士が接合され、膨張黒鉛シート３Ａ、３Ｂの内面は、熱交換パイプ２の表面に接触した状態となる。また、一対の膨張黒鉛シート３Ａ、３Ｂの密度は、接合作業時の圧縮によって所定の値となる。   Next, as shown in FIG. 4, the heat exchange pipe 2 is disposed between the expanded graphite sheets 3 </ b> A and 3 </ b> B formed on the stage 7 including the expanded graphite, and the pair of expanded graphite sheets 3 </ b> A and 3 </ b> B are connected to the heat exchange pipe. 2 and compress from above. By this compression, the joining surfaces 3c and 3d of the pair of expanded graphite sheets 3A and 3B are joined together, and the inner surfaces of the expanded graphite sheets 3A and 3B are in contact with the surface of the heat exchange pipe 2. Further, the density of the pair of expanded graphite sheets 3A and 3B becomes a predetermined value due to compression during the joining operation.

最後に、熱交換パイプ２及び保持部材４を収容して一体化された膨張黒鉛シート３Ａ、３Ｂをパネル本体５に組み込む。以上のようにして冷暖房用輻射パネル１が製造される。なお、当然、熱交換パイプ２を十分に養生して図３（ａ）の形状に保形できれば、保持部材４を省略することができる。   Finally, the expanded graphite sheets 3 </ b> A and 3 </ b> B that are integrated with the heat exchange pipe 2 and the holding member 4 are assembled into the panel body 5. As described above, the cooling / heating radiation panel 1 is manufactured. Naturally, the holding member 4 can be omitted if the heat exchange pipe 2 is sufficiently cured and held in the shape of FIG.

（実施の形態の動作）
次に、実施の形態の冷暖房用輻射パネル１の動作の一例について説明する。図示しない熱源装置から温度及び流量が制御された熱媒体が熱交換パイプ２に供給されると、熱交換パイプ２に供給された熱媒体は、直線部分２ａ及び曲線部分２ｂを循環して再び熱源装置に戻る。熱媒体が熱交換パイプ２を通過する間に、膨張黒鉛シート３Ａ、３Ｂ及びパネル本体５で熱交換され、冷暖房用輻射パネル１による輻射が行われて室内が冷暖房される。 (Operation of the embodiment)
Next, an example of operation | movement of the radiation panel 1 for air-conditioning of embodiment is demonstrated. When a heat medium whose temperature and flow rate are controlled is supplied to the heat exchange pipe 2 from a heat source device (not shown), the heat medium supplied to the heat exchange pipe 2 circulates through the straight portion 2a and the curved portion 2b and again becomes a heat source Return to the device. While the heat medium passes through the heat exchange pipe 2, heat is exchanged by the expanded graphite sheets 3A and 3B and the panel body 5, and radiation by the cooling and heating radiation panel 1 is performed to cool and heat the room.
