The heat transfer member 12 is a sheet material including a flat plate portion 21 which is a first portion joined to the heat transfer target and a bent portion 22 which is a second portion protruding from the end portion 19 shown in FIG. Is. The heat transfer member 12 is bent at a bending line between the flat plate portion 21 and the bending portion 22.

図１に示す２つの伝熱部材１２のうち一方の伝熱部材１２の平板部２１は、第１のシート材１３のうち第１の端面７に接合されている。かかる伝熱部材１２の折り曲げ部２２は、第１の端面７より下方へ向けて折り曲げられている。２つの伝熱部材１２のうち他方の伝熱部材１２の平板部２１は、第２のシート材１４のうち第２の端面８に接合されている。かかる伝熱部材１２の折り曲げ部２２は、第２の端面８より上方へ向けて折り曲げられている。伝熱部材１２は、平板部２１と折り曲げ部２２とが鈍角をなすように折り曲げられている。 The flat plate portion 21 of one of the two heat transfer members 12 shown in FIG. 1 is joined to the first end surface 7 of the first sheet material 13. The bent portion 22 of the heat transfer member 12 is bent downward from the first end surface 7. The flat plate portion 21 of the other heat transfer member 12 of the two heat transfer members 12 is joined to the second end surface 8 of the second sheet material 14. The bent portion 22 of the heat transfer member 12 is bent upward from the second end surface 8. The heat transfer member 12 is bent so that the flat plate portion 21 and the bent portion 22 form an obtuse angle.

伝熱部材１２の材料には、金属のうち比較的高い熱伝導率の金属であるアルミニウムあるいは銅が用いられている。伝熱部材１２の材料は、高い熱伝導率の材料であれば良く、アルミニウムあるいは銅以外の金属材料であっても良く、金属材料以外の材料であっても良い。 As the material of the heat transfer member 12, aluminum or copper, which is a metal having a relatively high thermal conductivity, is used. The material of the heat transfer member 12 may be a material having a high thermal conductivity, may be a metal material other than aluminum or copper, or may be a material other than the metal material.

折り曲げ部２２は、端部１９から突出していることで、積層体２から排気流１７の上流側へ露出している。積層体２へ向けて流動する排気流１７の一部は、折り曲げ部２２に当たる。 Since the bent portion 22 protrudes from the end portion 19, the bent portion 22 is exposed from the laminated body 2 to the upstream side of the exhaust flow 17. A part of the exhaust flow 17 flowing toward the laminated body 2 hits the bent portion 22.

室内からの排気流１７の温度が、屋外からの給気流１８の温度より高い場合には、全熱交換素子１は、排気流１７から得た熱を給気流１８へ伝える。伝熱部材１２は、積層体２へ向けて流動する排気流１７の一部を折り曲げ部２２にて受けることで、排気流１７からの熱を取り込む。伝熱部材１２は、取り込まれた熱を、平板部２１から第１のシート材１３および第２のシート材１４へ伝播させる。第１のシート材１３および第２のシート材１４へ伝播した熱は、間隔保持部材１１とシート材１０とを経て、第２の流路６を流動する給気流１８へ伝えられる。 When the temperature of the exhaust flow 17 from the room is higher than the temperature of the air supply 18 from the outside, the total heat exchange element 1 transfers the heat obtained from the exhaust flow 17 to the air supply 18. The heat transfer member 12 takes in heat from the exhaust flow 17 by receiving a part of the exhaust flow 17 flowing toward the laminated body 2 at the bent portion 22. The heat transfer member 12 propagates the taken-in heat from the flat plate portion 21 to the first sheet material 13 and the second sheet material 14. The heat propagated to the first sheet material 13 and the second sheet material 14 is transferred to the air flow 18 flowing through the second flow path 6 via the interval holding member 11 and the sheet material 10.

全熱交換素子１は、平板部２１と折り曲げ部２２とを含む伝熱部材１２が積層体２に設けられていることで、排気流１７の熱を効率良く給気流１８へ伝えることができる。平板部２１からの折り曲げ部分である折り曲げ部２２が伝熱部材１２に設けられていることで、かかる折り曲げが無い場合と比較して、伝熱部材１２への排気流１７の接触が増えることとなる。全熱交換素子１は、伝熱部材１２に折り曲げ部２２が設けられていることで、排気流１７から多くの熱を受けて、多くの熱を給気流１８へ伝えることができる。 In the total heat exchange element 1, the heat transfer member 12 including the flat plate portion 21 and the bent portion 22 is provided in the laminated body 2, so that the heat of the exhaust flow 17 can be efficiently transferred to the supply airflow 18. Since the heat transfer member 12 is provided with the bent portion 22 which is a bent portion from the flat plate portion 21, the contact of the exhaust flow 17 with the heat transfer member 12 is increased as compared with the case where there is no such bending. Become. Since the heat transfer member 12 is provided with the bent portion 22, the total heat exchange element 1 can receive a large amount of heat from the exhaust flow 17 and transfer a large amount of heat to the supply airflow 18.
