Description

本発明は、熱交換プレートに用いられる金属製元板材に関する。 The present invention relates to a metal original plate material used for a heat exchange plate.

作動媒体の凝縮熱伝達を利用するプレート式熱交換器が知られている。このプレート式熱交換器に内蔵される熱交換プレートは、熱交換効率や機械的耐久性の向上を目的として、通常、ヘリンボーン形状等の複雑な形状に成形される。このような熱交換プレートは、一般的に、金属製元板材をプレス加工することにより製造される。 Plate heat exchangers that utilize the heat transfer of condensed heat in the working medium are known. The heat exchange plate built into this plate heat exchanger is usually formed into a complicated shape such as a herringbone shape for the purpose of improving heat exchange efficiency and mechanical durability. Such a heat exchange plate is generally manufactured by pressing a metal base plate material.

熱交換プレートの熱交換効率をさらに向上させるために、プレス加工前の金属製元板材の表面に微細な複数の突条を設ける手法が提案されている（特許文献１）。特許文献１の元板材は、プレス加工前の金属製の平板材の表面に２種類の突条をＶ字形状となる角度で対称的に形成し、かつこれらの２種類の突条間に隙間を設けることで、作動媒体の蒸気に対する撹拌作用で作動媒体の凝縮を促進し、かつ作動媒体の凝縮液を効率よく排出できるとしている。 In order to further improve the heat exchange efficiency of the heat exchange plate, a method of providing a plurality of fine ridges on the surface of the metal base plate material before press working has been proposed (Patent Document 1). In the original plate material of Patent Document 1, two types of ridges are symmetrically formed on the surface of a metal flat plate material before press working at an angle of V shape, and a gap is formed between these two types of ridges. By providing the above, the stirring action of the working medium with respect to the steam promotes the condensation of the working medium, and the condensate of the working medium can be efficiently discharged.

特許文献１の元板材の表面に設けられる２種類の突条は、突条間に隙間を有する対称的なＶ字形状であるため、元板材の表面を流下する凝縮液は、２種類の突条の誘導により突条間に集中し、突条の下流側の端部間の隙間を通過する際に減速する。このため、凝縮液を板材表面に適切に分散させ、凝縮液をさらに効率よく排出させるためには新たな工夫が必要である。 Since the two types of ridges provided on the surface of the original plate material of Patent Document 1 have a symmetrical V-shape with a gap between the ridges, the condensate flowing down the surface of the original plate material has two types of ridges. It concentrates between the ridges due to the guidance of the ridges and slows down when passing through the gap between the ends on the downstream side of the ridges. Therefore, a new device is required to appropriately disperse the condensate on the surface of the plate material and to discharge the condensate more efficiently.

特開２０１５−１６１４４９号公報JP-A-2015-161449

本発明は、上述のような事情に基づいてなされたものであり、作動媒体の凝縮液を適切に分散し、かつ凝縮液を効率よく排出できる熱交換プレートに用いられる金属製元板材を提供することを目的とする。 The present invention has been made based on the above circumstances, and provides a metal base plate material used for a heat exchange plate capable of appropriately dispersing the condensate of the working medium and efficiently discharging the condensate. The purpose is.

上記課題を解決するためになされた発明は、プレート式熱交換器に内蔵される熱交換プレートに用いられる金属製元板材であって、少なくとも一方の表面が、複数の帯状の第１領域と複数の帯状の第２領域とを並列かつ交互に備え、帯状の上記第１領域が、長手方向との交角が１０度以上２５度以下となるように略平行かつ略等間隔に並ぶ複数の第１突条を有し、帯状の上記第２領域が、短手方向に上記複数の第１突条と対向する角度で略平行かつ略等間隔に並ぶ複数の第２突条を有し、上記第１領域と上記第２領域とが、隙間領域を介して略等間隔に離隔されており、上記第１領域及び上記第２領域の長手方向の一方を下流方向とした場合、上記複数の第１突条の下流側の第１端部と上記複数の第２突条の下流側の第２端部とが長手方向に互いにずれている。 The invention made to solve the above problems is a metal base plate material used for a heat exchange plate built in a plate heat exchanger, and at least one surface thereof is a plurality of strip-shaped first regions and a plurality of strips. A plurality of first regions in which the strip-shaped second regions are provided in parallel and alternately, and the strip-shaped first regions are arranged substantially in parallel and at substantially equal intervals so that the intersection angle with the longitudinal direction is 10 degrees or more and 25 degrees or less. The second region having a ridge and having a band shape has a plurality of second ridges arranged substantially parallel and at substantially equal intervals at an angle facing the plurality of first ridges in the lateral direction. When one region and the second region are separated at substantially equal intervals via a gap region, and one of the longitudinal direction of the first region and the second region is the downstream direction, the plurality of first regions The first end on the downstream side of the ridge and the second end on the downstream side of the plurality of second ridges are displaced from each other in the longitudinal direction.

当該金属製元板材は、第１領域と第２領域との間に隙間領域を備え、２種類の突条の端部を第１領域及び第２領域の長手方向にずらして配設しているので、２種類の突条の端部間への凝縮液の集中を抑制し、凝縮液を適切に分散できる。また、当該金属製元板材は、第１領域及び第２領域の長手方向との交角が１０度以上２５度以下となるように２種類の突条を配設しているので、流下する凝縮液の減速を抑制することにより凝縮液を効率よく排出できる。 The metal original plate material has a gap region between the first region and the second region, and the ends of the two types of ridges are arranged so as to be offset in the longitudinal direction of the first region and the second region. Therefore, the concentration of the condensate between the ends of the two types of ridges can be suppressed, and the condensate can be appropriately dispersed. Further, since the metal original plate material has two types of ridges arranged so that the angle of intersection with the longitudinal direction of the first region and the second region is 10 degrees or more and 25 degrees or less, the condensate flowing down. The condensate can be efficiently discharged by suppressing the deceleration of the metal.

上記複数の第１突条間の平均距離が０．１ｍｍ以上１．０ｍｍ以下であり、上記複数の第２突条間の平均距離が０．１ｍｍ以上１．０ｍｍ以下であり、上記第１領域及び上記第２領域間の平均距離が０．２ｍｍ以上１．５ｍｍ以下であるとよい。これにより、当該金属製元板材は、第１突条間の平均距離、第２突条間の平均距離並びに第１領域及び第２領域間の平均距離が適切に調整されるので、凝縮液を効率よく排出できる。 The average distance between the plurality of first ridges is 0.1 mm or more and 1.0 mm or less, the average distance between the plurality of second ridges is 0.1 mm or more and 1.0 mm or less, and the first region. The average distance between the second regions is 0.2 mm or more and 1.5 mm or less. As a result, in the metal base plate material, the average distance between the first ridges, the average distance between the second ridges, and the average distance between the first region and the second region are appropriately adjusted, so that the condensate can be mixed. Can be discharged efficiently.

上記第１端部及び上記第２端部間の長手方向のずれ量が、０．１ｍｍ以上５．８ｍｍ以下であるとよい。これにより、当該金属製元板材は、第１端部及び第２端部間の長手方向のずれ量が適切に調整されるので、凝縮液を適切に分散できる。 The amount of displacement in the longitudinal direction between the first end portion and the second end portion is preferably 0.1 mm or more and 5.8 mm or less. As a result, in the metal base plate material, the amount of displacement in the longitudinal direction between the first end portion and the second end portion is appropriately adjusted, so that the condensate can be appropriately dispersed.

本発明の熱交換プレートに用いられる金属製元板材は、作動媒体の凝縮液を適切に分散し、かつ凝縮液を効率よく排出できる。 The metal original plate material used for the heat exchange plate of the present invention can appropriately disperse the condensate of the working medium and efficiently discharge the condensate.

以下、本発明に係る熱交換プレートに用いられる金属製元板材の実施形態について図を参照しつつ詳説する。 Hereinafter, embodiments of the metal base plate used for the heat exchange plate according to the present invention will be described in detail with reference to the drawings.

［金属製元板材］
図１の金属製元板材１は、プレート式熱交換器に内蔵される熱交換プレートに用いられる金属製元板材である。金属製元板材１の材質としては、特に限定されないが、例えばチタンが用いられる。金属製元板材１は、熱交換プレートを製造するための素材となる平板材であり、プレート式熱交換器に内蔵される際には、プレス加工により熱交換プレートに成形される。金属製元板材１としては、特に限定されないが、長辺が１２００ｍｍ、短辺が８００ｍｍ、平均厚みが０．５ｍｍ以上１．０ｍｍ以下の矩形板が用いられる。 [Metal original plate material]
The metal base plate 1 of FIG. 1 is a metal base plate used for a heat exchange plate built in a plate heat exchanger. The material of the metal original plate material 1 is not particularly limited, but for example, titanium is used. The metal original plate material 1 is a flat plate material used as a material for manufacturing a heat exchange plate, and when it is incorporated in a plate type heat exchanger, it is formed into a heat exchange plate by press working. The metal original plate material 1 is not particularly limited, but a rectangular plate having a long side of 1200 mm, a short side of 800 mm, and an average thickness of 0.5 mm or more and 1.0 mm or less is used.

金属製元板材１の表面には、複数の帯状の第１領域２と複数の帯状の第２領域３とが並列かつ交互に設けられている。なお、第１領域２及び第２領域３を備える表面は、金属製元板材１の少なくとも一方の表面であればよく、金属製元板材１の片面のみであっても、金属製元板材１の両面であってもよい。 On the surface of the metal original plate material 1, a plurality of strip-shaped first regions 2 and a plurality of strip-shaped second regions 3 are provided in parallel and alternately. The surface including the first region 2 and the second region 3 may be at least one surface of the metal base plate material 1, and even if only one side of the metal base plate material 1 is provided, the metal base plate material 1 may have only one surface. It may be double-sided.

＜第１領域＞
第１領域２は、金属製元板材１の表面に設けられる帯状の領域であり、複数の第１領域２が略平行に設けられている。各第１領域２は、長手方向との交角がθ１となるように略平行かつ略等間隔に並ぶ複数の第１突条２１を有している。 <First area>
The first region 2 is a strip-shaped region provided on the surface of the metal original plate material 1, and a plurality of first regions 2 are provided substantially in parallel. Each first region 2 has a plurality of first ridges 21 arranged substantially parallel and at substantially equal intervals so that the angle of intersection with the longitudinal direction is θ1.

第１領域２の短手方向の平均幅Ｚ１の下限としては、１ｍｍが好ましく、２ｍｍがより好ましく、３ｍｍがさらに好ましい。一方、平均幅Ｚ１の上限としては、２０ｍｍが好ましく、１８ｍｍがより好ましく、１６ｍｍがさらに好ましい。平均幅Ｚ１が上記下限に満たないと、作動媒体の蒸気に対する撹拌作用が十分に得られず、作動媒体の凝縮が促進されないおそれがある。逆に、平均幅Ｚ１が上記上限を超えると、凝縮液が第１領域２に滞留し、凝縮液が効率よく排出されないおそれがある。なお、「平均幅」とは、１つの対象における任意の５点の幅を平均した値を示す。 As the lower limit of the average width Z1 in the lateral direction of the first region 2, 1 mm is preferable, 2 mm is more preferable, and 3 mm is further preferable. On the other hand, the upper limit of the average width Z1 is preferably 20 mm, more preferably 18 mm, and even more preferably 16 mm. If the average width Z1 is less than the above lower limit, the stirring action of the working medium with respect to the steam may not be sufficiently obtained, and the condensation of the working medium may not be promoted. On the contrary, when the average width Z1 exceeds the above upper limit, the condensate may stay in the first region 2 and the condensate may not be efficiently discharged. The "mean width" indicates a value obtained by averaging the widths of any five points in one object.

（第１突条）
第１領域２には、複数の第１突条２１が略平行かつ略等間隔に設けられている。第１突条２１は、平面視で細長い棒状の突条であり、その両端が帯状の第１領域２の両側部に届く長さを有している。なお、図１では、第１突条２１の形状が略矩形となっているが、第１突条２１は、平面視で２つの長辺が略平行に形成されていればよく、両端は例えば曲線形状であってもよい。また、金属製元板材１の表面に突条を形成する方法としては、特に限定されないが、例えば圧延時に凹凸を転写する方法等が採用される。 (1st article)
In the first region 2, a plurality of first ridges 21 are provided substantially parallel and at substantially equal intervals. The first ridge 21 is a rod-shaped ridge that is elongated in a plan view, and both ends thereof have a length that reaches both sides of the band-shaped first region 2. In FIG. 1, the shape of the first ridge 21 is substantially rectangular, but the first ridge 21 may have two long sides substantially parallel to each other in a plan view, and both ends thereof, for example. It may have a curved shape. Further, the method of forming the ridges on the surface of the metal base plate 1 is not particularly limited, but for example, a method of transferring unevenness during rolling is adopted.

第１突条２１と第１領域２の長手方向との交角θ１は、流下する凝縮液の減速を抑制するために鋭角に設定されている。交角θ１の下限としては、１０度が好ましく、１２度がより好ましく、１３度がさらに好ましい。一方、交角θ１の上限としては、２５度が好ましく、２２度がより好ましく、２０度がさらに好ましい。交角θ１が上記下限に満たないと、第１突条２１の側辺に沿って凝縮液が適切に誘導されないおそれがある。逆に、交角θ１が上記上限を超えると、凝縮液が第１領域２に滞留し、効率よく排出されないおそれがある。なお、「交角」とは、２直線が交差する際に形成する２つの角の内、鋭角のものを示す。 The intersection angle θ1 between the first ridge 21 and the longitudinal direction of the first region 2 is set to an acute angle in order to suppress the deceleration of the flowing condensate. As the lower limit of the intersection angle θ1, 10 degrees is preferable, 12 degrees is more preferable, and 13 degrees is further preferable. On the other hand, the upper limit of the intersection angle θ1 is preferably 25 degrees, more preferably 22 degrees, and even more preferably 20 degrees. If the intersection angle θ1 does not meet the above lower limit, the condensate may not be properly guided along the side side of the first ridge 21. On the contrary, if the intersection angle θ1 exceeds the above upper limit, the condensate may stay in the first region 2 and may not be efficiently discharged. The "intersection angle" refers to an acute angle among the two angles formed when the two straight lines intersect.

第１突条２１の短手方向の平均幅ａ１の下限としては、０．１０ｍｍが好ましく、０．１１ｍｍがより好ましく、０．１２ｍｍがさらに好ましい。一方平均幅ａ１の上限としては、１．０ｍｍが好ましく、０．８ｍｍがより好ましく、０．６ｍｍがさらに好ましい。平均幅ａ１が上記下限に満たないと、第１突条２１の強度が不十分となるおそれがある。逆に、平均幅ａ１が上記上限を超えると、凝縮液が第１突条２１の上面を流下し、第１突条２１の側辺に沿って凝縮液が適切に誘導されないおそれがある。 The lower limit of the average width a1 in the lateral direction of the first ridge 21 is preferably 0.10 mm, more preferably 0.11 mm, and even more preferably 0.12 mm. On the other hand, the upper limit of the average width a1 is preferably 1.0 mm, more preferably 0.8 mm, and even more preferably 0.6 mm. If the average width a1 does not meet the above lower limit, the strength of the first ridge 21 may be insufficient. On the contrary, when the average width a1 exceeds the above upper limit, the condensate may flow down the upper surface of the first ridge 21 and the condensate may not be properly guided along the side side of the first ridge 21.

２つの第１突条２１間の平均距離ｂ１の下限としては、０．１ｍｍが好ましく、０．２ｍｍがより好ましく、０．３ｍｍがさらに好ましい。一方、平均距離ｂ１の上限としては、１．０ｍｍが好ましく、０．９ｍｍがより好ましく、０．８ｍｍがさらに好ましい。平均距離ｂ１が上記下限に満たないと、凝縮液が第１突条２１の上面へ溢れてしまい、第１突条２１の側辺に沿って凝縮液が適切に誘導されないおそれがある。逆に、平均距離ｂ１が上記上限を超えると、凝縮液が第１突条２１間に滞留し、効率よく排出されないおそれがある。なお、「平均距離」とは、突条の短手方向における距離の平均であり、２つの突条間の任意の５つの距離を平均した値を示す。 The lower limit of the average distance b1 between the two first ridges 21 is preferably 0.1 mm, more preferably 0.2 mm, and even more preferably 0.3 mm. On the other hand, the upper limit of the average distance b1 is preferably 1.0 mm, more preferably 0.9 mm, and even more preferably 0.8 mm. If the average distance b1 is not less than the above lower limit, the condensate may overflow to the upper surface of the first ridge 21 and the condensate may not be properly guided along the side side of the first ridge 21. On the contrary, if the average distance b1 exceeds the above upper limit, the condensate may stay between the first ridges 21 and may not be discharged efficiently. The "average distance" is the average of the distances in the lateral direction of the ridges, and indicates the average value of any five distances between the two ridges.

金属製元板材１の表面に対する第１突条２１の平均高さｈの下限としては、０．０２ｍｍが好ましく、０．０３ｍｍがより好ましく、０．０４ｍｍがさらに好ましい。一方、平均高さｈの上限としては、０．１０ｍｍが好ましく、０．０９ｍｍがより好ましく、０．０８ｍｍがさらに好ましい。平均高さｈが上記下限に満たないと、作動媒体の蒸気に対する撹拌作用が十分に得られず、作動媒体の凝縮が促進されないおそれがある。逆に、平均高さｈが上記上限を超えると、加工コストが増大するおそれがある。 The lower limit of the average height h of the first ridge 21 with respect to the surface of the metal base plate 1 is preferably 0.02 mm, more preferably 0.03 mm, and even more preferably 0.04 mm. On the other hand, the upper limit of the average height h is preferably 0.10 mm, more preferably 0.09 mm, and even more preferably 0.08 mm. If the average height h is less than the above lower limit, the stirring action of the working medium with respect to the steam may not be sufficiently obtained, and the condensation of the working medium may not be promoted. On the contrary, if the average height h exceeds the above upper limit, the processing cost may increase.

＜第２領域＞
第２領域３は、第１領域２と同様に、金属製元板材１の表面に設けられる帯状の領域であり、複数の第２領域３が略平行に設けられている。各第２領域３は、短手方向に複数の第１突条２１と対向する角度θ２で略平行かつ略等間隔に並ぶ複数の第２突条３１を有している。 <Second area>
Similar to the first region 2, the second region 3 is a strip-shaped region provided on the surface of the metal original plate material 1, and a plurality of second regions 3 are provided substantially in parallel. Each second region 3 has a plurality of second ridges 31 that are substantially parallel and substantially evenly spaced at an angle θ2 facing the first ridges 21 in the lateral direction.

第２領域３の短手方向の平均幅Ｚ２の下限としては、１ｍｍが好ましく、２ｍｍがより好ましく、３ｍｍがさらに好ましい。一方、平均幅Ｚ２の上限としては、２０ｍｍが好ましく、１８ｍｍがより好ましく、１６ｍｍがさらに好ましい。平均幅Ｚ２が上記下限に満たないと、作動媒体の蒸気に対する撹拌作用が十分に得られず、作動媒体の凝縮が促進されないおそれがある。逆に、平均幅Ｚ２が上記上限を超えると、凝縮液が第２領域３に滞留し、凝縮液が効率よく排出されないおそれがある。 As the lower limit of the average width Z2 in the lateral direction of the second region 3, 1 mm is preferable, 2 mm is more preferable, and 3 mm is further preferable. On the other hand, the upper limit of the average width Z2 is preferably 20 mm, more preferably 18 mm, and even more preferably 16 mm. If the average width Z2 is not less than the above lower limit, the stirring action of the working medium with respect to steam may not be sufficiently obtained, and the condensation of the working medium may not be promoted. On the contrary, when the average width Z2 exceeds the above upper limit, the condensate may stay in the second region 3 and the condensate may not be efficiently discharged.

（第２突条）
第２領域３には、複数の第２突条３１が略平行かつ略等間隔に設けられている。第２突条３１は、第１突条２１と同様に、平面視で細長い棒状の突条であり、その両端が帯状の第２領域３の両側部に届く長さを有している。なお、図１では、第２突条３１の形状が第１突条２１の形状と同じ略矩形となっているが、第２突条３１は、第１突条２１と同様に、平面視で２つの長辺が略平行に形成されていればよい。また、凝縮液の流下量のバランスの観点から、第２突条３１は、平面視で第１突条２１と同じ形状であり、金属製元板材１の表面に対する第２突条３１の高さは、図２に示すように、金属製元板材１の表面に対する第１突条２１の高さｈと等しいと好ましい。 (2nd ridge)
In the second region 3, a plurality of second ridges 31 are provided substantially parallel and at substantially equal intervals. Like the first ridge 21, the second ridge 31 is an elongated rod-shaped ridge in a plan view, and both ends thereof have a length that reaches both sides of the strip-shaped second region 3. In FIG. 1, the shape of the second ridge 31 is substantially rectangular, which is the same as the shape of the first ridge 21, but the second ridge 31 is the same as the first ridge 21 in a plan view. It suffices if the two long sides are formed substantially parallel. Further, from the viewpoint of the balance of the flow amount of the condensate, the second ridge 31 has the same shape as the first ridge 21 in a plan view, and the height of the second ridge 31 with respect to the surface of the metal base plate 1 Is preferably equal to the height h of the first ridge 21 with respect to the surface of the metal base plate 1 as shown in FIG.

第２突条３１は、短手方向に第１突条２１と対向する角度で配設されているため、第１領域２及び第２領域３の長手方向の一方を下流方向とした場合、複数の第１突条２１の下流側の第１端部２１ａと複数の第２突条３１の下流側の第２端部３１ａとが隙間領域４を挟んで互いに近接している。 Since the second ridges 31 are arranged at an angle facing the first ridges 21 in the lateral direction, there are a plurality of the second ridges 31 when one of the longitudinal directions of the first region 2 and the second region 3 is the downstream direction. The first end portion 21a on the downstream side of the first ridge 21 and the second end portion 31a on the downstream side of the plurality of second ridges 31 are close to each other with the gap region 4 in between.

第２突条３１と第２領域３の長手方向との交角θ２は、流下する凝縮液の減速を抑制するために鋭角に設定されている。交角θ２の下限としては、１０度が好ましく、１２度がより好ましく、１３度がさらに好ましい。一方、交角θ２の上限としては、２５度が好ましく、２２度がより好ましく、２０度がさらに好ましい。交角θ２が上記下限に満たないと、第２突条３１の側辺に沿って凝縮液が適切に誘導されないおそれがある。逆に、交角θ２が上記上限を超えると、凝縮液が第２領域３に滞留し、効率よく排出されないおそれがある。なお、凝縮液の流下量のバランスの観点から、交角θ１及び交角θ２の絶対値は等しいと好ましい。 The intersection angle θ2 between the second ridge 31 and the longitudinal direction of the second region 3 is set to an acute angle in order to suppress the deceleration of the flowing condensate. As the lower limit of the intersection angle θ2, 10 degrees is preferable, 12 degrees is more preferable, and 13 degrees is further preferable. On the other hand, the upper limit of the intersection angle θ2 is preferably 25 degrees, more preferably 22 degrees, and even more preferably 20 degrees. If the intersection angle θ2 does not meet the above lower limit, the condensate may not be properly guided along the side side of the second ridge 31. On the contrary, if the intersection angle θ2 exceeds the above upper limit, the condensate may stay in the second region 3 and may not be efficiently discharged. From the viewpoint of the balance of the flow rate of the condensate, it is preferable that the absolute values of the intersection angle θ1 and the intersection angle θ2 are equal.

第２突条３１の短手方向の平均幅ａ２の下限としては、０．１０ｍｍが好ましく、０．１１ｍｍがより好ましく、０．１２ｍｍがさらに好ましい。一方平均幅ａ２の上限としては、１．０ｍｍが好ましく、０．８ｍｍがより好ましく、０．６ｍｍがさらに好ましい。平均幅ａ２が上記下限に満たないと、第２突条３１の強度が不十分となるおそれがある。逆に、平均幅ａ２が上記上限を超えると、凝縮液が第２突条３１の上面を流下し、第２突条３１の側辺に沿って凝縮液が適切に誘導されないおそれがある。なお、凝縮液の流下量のバランスの観点から、平均幅ａ１及び平均幅ａ２は等しいと好ましい。 The lower limit of the average width a2 in the lateral direction of the second ridge 31 is preferably 0.10 mm, more preferably 0.11 mm, and even more preferably 0.12 mm. On the other hand, the upper limit of the average width a2 is preferably 1.0 mm, more preferably 0.8 mm, and even more preferably 0.6 mm. If the average width a2 does not meet the above lower limit, the strength of the second ridge 31 may be insufficient. On the contrary, when the average width a2 exceeds the above upper limit, the condensate may flow down the upper surface of the second ridge 31, and the condensate may not be properly guided along the side side of the second ridge 31. From the viewpoint of the balance of the flow-down amount of the condensate, it is preferable that the average width a1 and the average width a2 are equal.

２つの第２突条３１間の平均距離ｂ２の下限としては、０．１ｍｍが好ましく、０．２ｍｍがより好ましく、０．３ｍｍがさらに好ましい。一方、平均距離ｂ２の上限としては、１．０ｍｍが好ましく、０．９ｍｍがより好ましく、０．８ｍｍがさらに好ましい。平均距離ｂ２が上記下限に満たないと、凝縮液が第２突条３１の上面へ溢れてしまい、第２突条３１の側辺に沿って凝縮液が適切に誘導されないおそれがある。逆に、平均距離ｂ２が上記上限を超えると、凝縮液が第２突条３１間に滞留し、効率よく排出されないおそれがある。なお、凝縮液の流下量のバランスの観点から、平均距離ｂ１及び平均距離ｂ２は等しいと好ましい。 The lower limit of the average distance b2 between the two second ridges 31 is preferably 0.1 mm, more preferably 0.2 mm, and even more preferably 0.3 mm. On the other hand, the upper limit of the average distance b2 is preferably 1.0 mm, more preferably 0.9 mm, and even more preferably 0.8 mm. If the average distance b2 is not less than the above lower limit, the condensate may overflow to the upper surface of the second ridge 31, and the condensate may not be properly guided along the side side of the second ridge 31. On the contrary, if the average distance b2 exceeds the above upper limit, the condensate may stay between the second ridges 31 and may not be efficiently discharged. From the viewpoint of the balance of the flow-down amount of the condensate, it is preferable that the average distance b1 and the average distance b2 are equal.

第１領域２及び第２領域３の長手方向の一方を下流方向とした場合、複数の第１突条２１の下流側の第１端部２１ａと複数の第２突条３１の下流側の第２端部３１ａとは、長手方向に互いにずれている。第１端部２１ａ及び第２端部３１ａ間の長手方向のずれ量としては、第１端部２１ａが第２端部３１ａより下流側である場合のずれ量Ｗ１と、第１端部２１ａが第２端部３１ａより上流側である場合のずれ量Ｗ２とが存在するが、凝縮液の流下量のバランスの観点から、ずれ量Ｗ１及びずれ量Ｗ２は等しいと好ましいが、特に限定されず、ずれ量Ｗ１及びずれ量Ｗ２は異なっていてもよい。なお、突条の下流側の端部とは、突条の上流側の長辺における下流側の終端部を示す。 When one of the longitudinal directions of the first region 2 and the second region 3 is the downstream direction, the first end portion 21a on the downstream side of the plurality of first ridges 21 and the second downstream side of the plurality of second ridges 31 The two ends 31a are displaced from each other in the longitudinal direction. As the displacement amount in the longitudinal direction between the first end portion 21a and the second end portion 31a, the displacement amount W1 when the first end portion 21a is on the downstream side of the second end portion 31a and the first end portion 21a are There is a deviation amount W2 when it is on the upstream side of the second end 31a, but from the viewpoint of the balance of the flow-down amount of the condensate, it is preferable that the deviation amount W1 and the deviation amount W2 are equal, but it is not particularly limited. The deviation amount W1 and the deviation amount W2 may be different. The downstream end of the ridge indicates the downstream end of the long side of the ridge on the upstream side.

第１端部２１ａ及び第２端部３１ａ間の長手方向のずれ量Ｗ１の下限としては、０．１ｍｍが好ましく、０．６ｍｍがより好ましく、１．０ｍｍがさらに好ましい。一方、平均距離ｂ２の上限としては、５．８ｍｍが好ましく、４．５ｍｍがより好ましく、３．５ｍｍがさらに好ましい。ずれ量Ｗ１が上記下限に満たないと、第１端部２１ａ及び第２端部３１ａ間への凝縮液の集中が抑制されず、凝縮液が適切に分散されないおそれがある。逆に、ずれ量Ｗ１が上記上限を超えると、第１突条２１及び第２突条３１に沿って凝縮液が適切に誘導されないおそれがある。なお、ずれ量Ｗ２の下限及び上限についてもＷ１と同様である。 The lower limit of the amount of deviation W1 in the longitudinal direction between the first end portion 21a and the second end portion 31a is preferably 0.1 mm, more preferably 0.6 mm, and even more preferably 1.0 mm. On the other hand, the upper limit of the average distance b2 is preferably 5.8 mm, more preferably 4.5 mm, and even more preferably 3.5 mm. If the deviation amount W1 does not meet the above lower limit, the concentration of the condensate between the first end 21a and the second end 31a is not suppressed, and the condensate may not be properly dispersed. On the contrary, if the deviation amount W1 exceeds the above upper limit, the condensate may not be properly induced along the first ridge 21 and the second ridge 31. The lower and upper limits of the deviation amount W2 are the same as those of W1.

＜隙間領域＞
第１領域２と第２領域３とは、隙間領域４を介して略等間隔に離隔されている。隙間領域４は、第１領域２及び第２領域３の長手方向と平行な帯状の領域であり、第１領域２及び第２領域３はこの隙間領域４を挟んで平行に配設されている。隙間領域４には、突条等の凹凸が形成されておらず、凝縮液の大部分は蛇行しながらこの隙間領域４を流下する。 <Gap area>
The first region 2 and the second region 3 are separated from each other at substantially equal intervals via the gap region 4. The gap region 4 is a strip-shaped region parallel to the longitudinal direction of the first region 2 and the second region 3, and the first region 2 and the second region 3 are arranged in parallel with the gap region 4 interposed therebetween. ..

第１領域２及び第２領域３間の平均距離Ｘの下限としては、０．２ｍｍが好ましく、０．３ｍｍがより好ましく、０．４ｍｍがさらに好ましい。一方、平均距離Ｘの上限としては、４．０ｍｍが好ましく、３．５ｍｍがより好ましく、３．０ｍｍがさらに好ましい。平均距離Ｘが上記下限に満たないと、凝縮液が効率よく排出されないおそれがある。逆に、平均距離Ｘが上記上限を超えると、第１突条２１及び第２突条３１に沿って凝縮液が適切に誘導されないおそれがある。 The lower limit of the average distance X between the first region 2 and the second region 3 is preferably 0.2 mm, more preferably 0.3 mm, and even more preferably 0.4 mm. On the other hand, the upper limit of the average distance X is preferably 4.0 mm, more preferably 3.5 mm, and even more preferably 3.0 mm. If the average distance X is less than the above lower limit, the condensate may not be efficiently discharged. On the contrary, if the average distance X exceeds the above upper limit, the condensate may not be properly guided along the first ridge 21 and the second ridge 31.
