The height is a relative height relationship, and the high portion H can be regarded as a region that protrudes as a whole when the low portion L is used as a reference.
　第１伝熱プレート３ａ、３ｂ、３ｃ、３ｄおよび第２伝熱プレート４ａ、４ｂ、４ｃ、４ｄのそれぞれには、上記の矩形でいう４隅の部分に、開口部２１が設けられている。開口部２１はそれぞれ、対応するプレートを貫通している。開口部２１には、プレートが積層された状態で対応する流体が流通する。第１伝熱プレート３ａ、３ｂ、３ｃ、３ｄおよび第２伝熱プレート４ａ、４ｂ、４ｃ、４ｄのそれぞれにおいて、一対の開口部２１は、低部Ｌの隅部に位置しており、別の一対の開口部２１は、高部Ｈの隅部に位置している。 Each of the first heat transfer plates 3a, 3b, 3c, and 3d and the second heat transfer plates 4a, 4b, 4c, and 4d is provided with openings 21 at the four corners of the rectangle.

　仕切りプレート５には、上記の矩形でいう４隅のうちの１つの隅に、開口部２２が設けられている。開口部２２は、仕切りプレート５を貫通している。仕切りプレート５の開口部２２は、第１流体１１が第１熱交換ユニット１から第２熱交換ユニット２へと移動するための流路となる。開口部２２は、仕切りプレート５の高部Ｈに位置している。仕切りプレート５の低部Ｌには、第１伝熱プレート３ａ、３ｂ、３ｃ、３ｄおよび第２伝熱プレート４ａ、４ｂ、４ｃ、４ｄとは異なり、凹凸部が形成されていない。つまり、仕切りプレート５の低部Ｌは、積層状態でみたときの一面側および他面側ともに、平坦に形成されている。 The partition plate 5 is provided with an opening 22 at one of the four corners in the rectangle. The opening 22 penetrates the partition plate 5. The opening 22 of the partition plate 5 serves as a flow path for the first fluid 11 to move from the first heat exchange unit 1 to the second heat exchange unit 2. The opening 22 is located at the high part H of the partition plate 5. Unlike the first heat transfer plates 3a, 3b, 3c, and 3d and the second heat transfer plates 4a, 4b, 4c, and 4d, the uneven portion is not formed in the lower portion L of the partition plate 5. That is, the low part L of the partition plate 5 is formed flat on both the one surface side and the other surface side when viewed in the laminated state.
　第１外側プレート６および第２外側プレート７は、上述した高部Ｈおよび低部Ｌの区別のない、全体の高さが一様な、平坦な板状部材である。第１外側プレート６および第２外側プレート７は、上記の矩形でいう４隅のうちの３つの隅に、開口部２３が設けられている。第１外側プレート６の３つの開口部２３は、第１熱交換ユニット１に関する出入口であり、第２外側プレート７の３つの開口部２３は、第２熱交換ユニット２に関する出入口である。第１外側プレート６および第２外側プレート７には、第１伝熱プレート３ａ、３ｂ、３ｃ、３ｄおよび第２伝熱プレート４ａ、４ｂ、４ｃ、４ｄのような凹凸部は形成されていない。つまり、第１外側プレート６および第２外側プレート７は、積層状態でみたときの一面側および他面側ともに、平坦に形成されている。 The first outer plate 6 and the second outer plate 7 are flat plate-like members having a uniform overall height without distinction between the above-described high portion H and low portion L.

That is, the first outer plate 6 and the second outer plate 7 are formed flat on both the one surface side and the other surface side when viewed in a stacked state.
　本発明では、仕切りプレート５の隣の第１伝熱プレート３ｄには、第１凹凸部３１ａが設けられており、第１凹凸部３１ａは、第１方向に延びる部分を有している。一方、仕切りプレート５の隣の第２伝熱プレート４ａには、第２凹凸部３１ｂが設けられており、第２凹凸部３１ｂは、第２方向に延びる部分を有している。すなわち、第１熱交換ユニット１は、第１エンドプレートである第１伝熱プレート３ａと、第２エンドプレートである第１伝熱プレート３ｄとを含み、第２エンドプレートである第１伝熱プレート３ｄは、第１エンドプレートから離れた第２エンドプレートの一側面に、第１畝部である第１凹凸部３１ａを有している。また、第２熱交換ユニット２は、第２エンドプレートと対面する第３エンドプレートである第２伝熱プレート４ａと、第３エンドプレートを介して第２エンドプレートの反対にある第４エンドプレートである第２伝熱プレート４ｄを有し、第３エンドプレートは、第４エンドプレートから離れた第３エンドプレートの一側面に、第２畝部である第２凹凸部３１ｂを有している。
　そして、第１方向と第２方向とは、第１伝熱プレート３ａ、３ｂ、３ｃ、３ｄ、仕切りプレート５および第２伝熱プレート４ａ、４ｂ、４ｃ、４ｄの積層方向に投影的にみて、交差している。これにつき、本実施の形態１の具体的構成例に基づき、さらに詳細に説明する。 In the present invention, the first heat transfer plate 3d adjacent to the partition plate 5 is provided with the first uneven portion 31a, and the first uneven portion 31a has a portion extending in the first direction. On the other hand, the 2nd uneven part 31b is provided in the 2nd heat exchanger plate 4a adjacent to the partition plate 5, and the 2nd uneven part 31b has a part extended in a 2nd direction. That is, the first heat exchange unit 1 includes a first heat transfer plate 3a that is a first end plate and a first heat transfer plate 3d that is a second end plate, and the first heat transfer unit that is a second end plate. The plate 3d has a first concavo-convex portion 31a that is a first flange portion on one side surface of the second end plate that is separated from the first end plate. The second heat exchange unit 2 includes a second heat transfer plate 4a that is a third end plate facing the second end plate, and a fourth end plate that is opposite to the second end plate via the third end plate. The third heat transfer plate 4d, and the third end plate has a second concavo-convex portion 31b as a second flange on one side surface of the third end plate away from the fourth end plate. .
The first direction and the second direction are projected in the stacking direction of the first heat transfer plates 3a, 3b, 3c, 3d, the partition plate 5 and the second heat transfer plates 4a, 4b, 4c, 4d, Crossed. This will be described in more detail based on the specific configuration example of the first embodiment.
　仕切りプレート５の隣の第１伝熱プレート３ｄには、上記積層方向からみて、すなわち、図４の紙面においてみて、Ｖ字状に延びる第１凹凸部３１ａが設けられている。第１凹凸部３１ａは、図４および図９に示されるように、山部と谷部とが繰り返されることによって構成されており、山部および谷部のそれぞれが、Ｖ字状に延びている。図３～図８は全て、紙面が、熱交換器設置時つまり使用時の上下方向となるように描かれている。よって、図４から分かるように、第１凹凸部３１ａは、Ｖ字の屈曲が上向きになるように形成されている。また、第１凹凸部３１ａのＶ字の屈曲は、左右方向の中心に並ぶように形成されており、つまり、第１凹凸部３１ａのＶ字は左右対称となっている。 The first heat transfer plate 3d adjacent to the partition plate 5 is provided with a first concavo-convex portion 31a extending in a V shape when viewed from the stacking direction, that is, when viewed on the paper surface of FIG. As shown in FIGS. 4 and 9, the first uneven portion 31 a is configured by repeating a peak portion and a valley portion, and each of the peak portion and the valley portion extends in a V shape. . 3 to 8 are all drawn so that the paper surface is in the vertical direction when the heat exchanger is installed, that is, when it is used. Therefore, as can be seen from FIG. 4, the first concavo-convex portion 31a is formed so that the V-shaped bend is directed upward. Further, the V-shaped bends of the first uneven portion 31a are formed so as to be aligned in the center in the left-right direction, that is, the V-shape of the first uneven portion 31a is left-right symmetrical.
　一方、仕切りプレート５の隣の第２伝熱プレート４ａにも、同様に、上記積層方向からみて、すなわち、図５の紙面においてみて、Ｖ字状に延びる第２凹凸部３１ｂが設けられている。第２凹凸部３１ｂもまた、山部と谷部とが繰り返されることによって構成されており、山部および谷部のそれぞれが、Ｖ字状に延びている。第２凹凸部３１ｂは、図５から分かるように、Ｖ字の屈曲が下向きになるように形成されている。また、第２凹凸部３１ｂのＶ字の屈曲は、左右方向の中心に並ぶように形成されており、つまり、第２凹凸部３１ｂのＶ字は左右対称となっている。すなわち、第１凹凸部３１ａと、第２凹凸部３１ｂとは、上下が逆になっている。言い換えると、第１稜線は、Ｖ字状に延びており、第２稜線は、Ｖ字状に延びており、第１稜線と、第２稜線とは、積層方向に投影的にみて、上下逆向きになっている。なお、第１凹凸部３１ａおよび第２凹凸部３１ｂに関しては、図４および図５の紙面表側からみて、谷部を実線で示し、山部は点線で示している。 On the other hand, the second heat transfer plate 4a adjacent to the partition plate 5 is similarly provided with a second uneven portion 31b extending in a V shape when viewed from the stacking direction, that is, when viewed in the plane of FIG. . The second concavo-convex part 31b is also configured by repeating a peak part and a valley part, and each of the peak part and the valley part extends in a V shape. As can be seen from FIG. 5, the second concavo-convex portion 31 b is formed so that the V-shaped bend is directed downward. Further, the V-shaped bending of the second uneven portion 31b is formed so as to be aligned in the center in the left-right direction, that is, the V-shape of the second uneven portion 31b is bilaterally symmetric. That is, the first uneven portion 31a and the second uneven portion 31b are upside down. In other words, the first ridge line extends in a V shape, the second ridge line extends in a V shape, and the first ridge line and the second ridge line are upside down in a projection direction in the stacking direction. It is facing. In addition, regarding the 1st uneven | corrugated | grooved part 31a and the 2nd uneven | corrugated | grooved part 31b seeing from the paper surface front side of FIG. 4 and FIG. 5, the trough part is shown as the continuous line, and the peak part is shown with the dotted line.
　第１凹凸部３１ａは、図４に示されるように、第１方向Ｄ１に延びる部分を有している。一方、第２凹凸部３１ｂは、この第１凹凸部３１ａの第１方向Ｄ１に延びる部分と、積層状態で重なる部分（積層方向に投影的にみて第１凹凸部３１ａの第１方向Ｄ１に延びる部分と対応する部分）に、第２方向Ｄ２に延びる部分を有している。よって、図１０に示されるように、第１方向Ｄ１と第２方向Ｄ２とは、積層方向に投影的にみて、交差している。特に、本実施の形態１では、第１凹凸部３１ａのＶ字と、第２凹凸部３１ｂのＶ字とが、上述したように構成されているため、第１凹凸部３１ａの全体と、第２凹凸部３１ｂの全体とが、積層方向に投影的にみて、交差している。すなわち、第１畝部は、第１稜線である上記の山部を有し、第２畝部は、第２稜線である上記の山部を有し、第１稜線と、第２稜線とは、仕切りプレートを介して、互いにねじれの位置にある。 The 1st uneven part 31a has a part extended in the 1st direction D1, as FIG. 4 shows. On the other hand, the second concavo-convex portion 31b extends in the first direction D1 of the first concavo-convex portion 31a when viewed from the projection direction in the stacking direction (the projection direction in the stacking direction) with the portion extending in the first direction D1 of the first concavo-convex portion 31a. (Part corresponding to the part) has a part extending in the second direction D2. Therefore, as shown in FIG. 10, the first direction D1 and the second direction D2 intersect with each other in a projection direction in the stacking direction. In particular, in the first embodiment, since the V-shape of the first uneven portion 31a and the V-shape of the second uneven portion 31b are configured as described above, the entire first uneven portion 31a and the first The entire two concavo-convex portions 31b intersect in the stacking direction in a projection manner. That is, the 1st ridge has the above-mentioned mountain part which is the 1st ridgeline, the 2nd ridge has the above-mentioned mountain part which is the 2nd ridgeline, and the 1st ridgeline and the 2nd ridgeline are , Through the partition plate, in a twisted position relative to each other.
　このように構成されたプレート式熱交換器１０１の作用を説明する。第１熱交換ユニット１においては、積層されて隣り合う一対の第１伝熱プレートの間に流路が確保され、複数の流路には、積層方向でみて交互に、第１流体１１および第２流体１２が流れる。これにより、第１流体１１および第２流体１２の間で熱交換が行われる。また、第２熱交換ユニット２においても同様であり、積層されて隣り合う一対の第２伝熱プレートの間に流路が確保され、複数の流路には、積層方向でみて交互に、第１流体１１および第３流体１３が流れる。これにより、第１流体１１および第３流体１３の間で熱交換が行われる。 The operation of the plate heat exchanger 101 configured as described above will be described. In the first heat exchange unit 1, a flow path is secured between a pair of adjacent first heat transfer plates that are stacked, and the plurality of flow paths alternately include the first fluid 11 and the first flow when viewed in the stacking direction. Two fluids 12 flow. Thereby, heat exchange is performed between the first fluid 11 and the second fluid 12. The same applies to the second heat exchange unit 2, and a flow path is secured between a pair of adjacent stacked second heat transfer plates, and the plurality of flow paths are alternately arranged in the stacking direction. The 1st fluid 11 and the 3rd fluid 13 flow. Thereby, heat exchange is performed between the first fluid 11 and the third fluid 13.
　また、仕切りプレート５の隣の第１伝熱プレート３ｄと、仕切りプレート５との間では、積層状態でみたときの他面側（仕切りプレート５と対面している側）の山部（すなわち一面側からみたときの谷部）が、仕切りプレート５の平坦な一面に当接する。この当接により、仕切りプレート５の隣の第１伝熱プレート３ｄと、仕切りプレート５との間では、上下方向の流路が遮断され、仕切りプレート５の隣の第１伝熱プレート３ｄと、仕切りプレート５との間は、流体が充満されず空気が十分に確保された領域が生じる。すなわち、図３にも示されているように、仕切りプレート５の隣の第１伝熱プレート３ｄと、仕切りプレート５との間には、流体は流れない。これにより、第１熱交換ユニット１と第２熱交換ユニット２との間での熱交換が抑制でき、第１熱交換ユニット１と第２熱交換ユニット２との間の熱交換に起因した熱交換ロスを低減することができる。さらに加えて、本実施の形態１では、仕切りプレート５の隣の第１伝熱プレート３ｄの第１凹凸部３１ａの第１方向Ｄ１と、仕切りプレート５の隣の第２伝熱プレート４ａの第２方向Ｄ２とは、図１０に示されるように、積層方向に投影的にみて、交差している。このため、第１熱交換ユニット１と第２熱交換ユニット２との間の伝熱経路が縮小しており、第１熱交換ユニットと第２熱交換ユニットとの間での熱交換を大いに低減することができる。なお、本実施の形態１の好適な一例では、第１凹凸部３１ａのＶ字の上向きの屈曲頂点３１ａ’と、第２凹凸部３１ｂのＶ字の下向きの屈曲頂点３１ｂ’とは、図１０に示されるように、すなわち、積層方向に投影的にみて、重ならないように構成されている。よって、積層方向に投影的にみて、第１凹凸部３１ａと第２凹凸部３１ｂとの交差点は、極めて少なくなっており、これにより、第１熱交換ユニットと第２熱交換ユニットとの間での熱交換を、より一層低減することができる。 In addition, between the first heat transfer plate 3d adjacent to the partition plate 5 and the partition plate 5, the other surface side (side facing the partition plate 5) when viewed in a stacked state (that is, one surface). The valley when viewed from the side abuts against the flat surface of the partition plate 5. By this contact, the flow path in the vertical direction is blocked between the first heat transfer plate 3d adjacent to the partition plate 5 and the partition plate 5, and the first heat transfer plate 3d adjacent to the partition plate 5 Between the partition plate 5, the area | region where the fluid was not filled but air was fully ensured arises. That is, as shown in FIG. 3, no fluid flows between the first heat transfer plate 3 d adjacent to the partition plate 5 and the partition plate 5. Thereby, the heat exchange between the 1st heat exchange unit 1 and the 2nd heat exchange unit 2 can be controlled, and the heat resulting from the heat exchange between the 1st heat exchange unit 1 and the 2nd heat exchange unit 2 Exchange loss can be reduced. In addition, in the first embodiment, the first direction D1 of the first uneven portion 31a of the first heat transfer plate 3d adjacent to the partition plate 5 and the second heat transfer plate 4a adjacent to the partition plate 5 are used. As shown in FIG. 10, the two directions D2 intersect with each other in a projection direction in the stacking direction. For this reason, the heat transfer path between the first heat exchange unit 1 and the second heat exchange unit 2 is reduced, and the heat exchange between the first heat exchange unit and the second heat exchange unit is greatly reduced. can do. In a preferred example of the first embodiment, the V-shaped upward bending vertex 31a ′ of the first uneven portion 31a and the V-shaped downward bending vertex 31b ′ of the second uneven portion 31b are shown in FIG. That is, it is configured so as not to overlap in the projection direction in the stacking direction. Therefore, the number of intersections between the first concavo-convex portion 31a and the second concavo-convex portion 31b is extremely small in a projection direction in the stacking direction, and thus, between the first heat exchange unit and the second heat exchange unit. The heat exchange can be further reduced.

FIG.
A second embodiment of the present invention will be described with reference to FIG. FIG. 11 shows a stacked state of the first heat transfer plate 3d adjacent to the partition plate 5, the partition plate 5, and the second heat transfer plate 4a adjacent to the partition plate 5 in the second embodiment of the present invention. FIG. Further, FIG. 11 schematically shows a cross section taken along the cutting line in the left-right direction as shown in FIG. 9. For easy understanding, the first heat transfer plate 3 d adjacent to the partition plate 5, the partition plate 5, The illustration of the thickness of the second heat transfer plate 4a adjacent to the partition plate 5 is omitted. The second embodiment is the same as the first embodiment described above except for the parts described below.
　本実施の形態２は、以下に説明する特徴の何れかを備えているものとする。まず、第１の特徴として、仕切りプレート５の隣の第２伝熱プレート４ａの第２凹凸部２３１ｂは、少なくとも２種類の高さを有している。そして、第２凹凸部２３１ｂの仕切りプレート５側の山部のうち、相対的に高い山部だけが仕切りプレート５に当接し、第２凹凸部２３１ｂの仕切りプレート５側の山部のうち、相対的に低い山部は、仕切りプレート５から離隔している。 The second embodiment is assumed to have any of the features described below. First, as a first feature, the second uneven portion 231b of the second heat transfer plate 4a adjacent to the partition plate 5 has at least two types of height. Of the peaks on the partition plate 5 side of the second uneven portion 231b, only the relatively high peaks contact the partition plate 5, and the peaks on the partition plate 5 side of the second uneven portion 231b The extremely low peak is separated from the partition plate 5.
　第２の特徴として、仕切りプレート５の隣の第１伝熱プレート３ｄの第１凹凸部２３１ａは、少なくとも２種類の高さを有している。そして、第１凹凸部２３１ａの仕切りプレート５側の山部のうち、相対的に高い山部だけが仕切りプレート５に当接し、第１凹凸部２３１ａの仕切りプレート５側の山部のうち、相対的に低い山部は、仕切りプレート５から離隔している。すなわち、第１畝部のうち、相対的に高い畝部だけが仕切りプレートに当接し、第１畝部のうち、相対的に低い畝部は、仕切りプレートから離隔しており、第２畝部のうち、相対的に高い畝部だけが仕切りプレートに当接し、第２畝部のうち、相対的に低い畝部は、仕切りプレートから離隔している。 As a second feature, the first uneven portion 231a of the first heat transfer plate 3d adjacent to the partition plate 5 has at least two types of height. And among the crests on the partition plate 5 side of the first uneven part 231a, only the relatively high crests abut against the partition plate 5, and among the crest parts on the partition plate 5 side of the first uneven part 231a, The extremely low peak is separated from the partition plate 5. That is, only a relatively high collar part of the first collar part contacts the partition plate, and a relatively low collar part of the first collar part is separated from the partition plate, and the second collar part Of these, only the relatively high collar portion is in contact with the partition plate, and among the second collar portions, the relatively low collar portion is separated from the partition plate.
　第３の特徴として、上述した第１の特徴と第２の特徴とを含み、さらに、第１凹凸部２３１ａと仕切りプレート５とが当接しているポイントＰ１と、第２凹凸部３１ｂと仕切りプレート５とが当接しているポイントＰ２とは、積層方向Ｓには並んでいない。つまり、第１畝部と仕切りプレートとが当接しているポイントと、第２畝部と仕切りプレートとが当接しているポイントとは、積層方向には並んでいない。 The third feature includes the first feature and the second feature described above, and further includes a point P1 where the first uneven portion 231a and the partition plate 5 are in contact, a second uneven portion 31b, and the partition plate. The point P2 with which 5 is in contact is not aligned in the stacking direction S. That is, the point at which the first collar part and the partition plate are in contact with the point at which the second collar part and the partition plate are in contact is not aligned in the stacking direction.
　上述した本実施の形態２によれば、実施の形態１で得られる作用効果に加えて、次のような作用効果も得られる。第１の特徴では、第２凹凸部３１ｂと仕切りプレート５との当接箇所が存在することで耐圧強度を確保すると共に当該当接箇所を減らすことで望ましくない熱交換を抑制することができる。第２の特徴も同様であり、第１凹凸部２３１ａと仕切りプレート５との当接箇所が存在することで耐圧強度を確保すると共に当該当接箇所を減らすことで望ましくない熱交換を抑制することができる。さらに、第３の特徴によれば、第１凹凸部２３１ａと第２凹凸部３１ｂとの双方が、仕切りプレート５と当接することで、第１の特徴および第２の特徴以上に、耐圧強度を確保することが可能でありながら、第１凹凸部２３１ａ、仕切りプレート５、第２凹凸部３１ｂが積層方向に直線的に揃っていないことで、第１熱交換ユニット１と第２熱交換ユニット２との間での熱交換を低減することができる。すなわち、望ましくない熱交換の抑制と、耐圧強度の向上との双方を促進することができる。 According to the second embodiment described above, in addition to the functions and effects obtained in the first embodiment, the following functions and effects can be obtained. In the first feature, the presence of a contact portion between the second concavo-convex portion 31b and the partition plate 5 can ensure the pressure resistance and reduce the contact portion, thereby suppressing undesirable heat exchange. The same applies to the second feature, and the presence of a contact portion between the first concavo-convex portion 231a and the partition plate 5 secures the pressure resistance and suppresses undesirable heat exchange by reducing the contact portion. Can do. Furthermore, according to the third feature, both the first concavo-convex portion 231a and the second concavo-convex portion 31b are in contact with the partition plate 5, so that the pressure strength is higher than that of the first feature and the second feature. The first heat exchange unit 1 and the second heat exchange unit 2 can be ensured because the first uneven portion 231a, the partition plate 5, and the second uneven portion 31b are not linearly aligned in the stacking direction. The heat exchange between the two can be reduced. That is, it is possible to promote both suppression of undesirable heat exchange and improvement of pressure strength.
　実施の形態３．
　本発明の実施の形態３について、図１２を用いて説明する。図１２は、本発明の実施の形態３に関する、図４と同態様の図である。なお、本実施の形態３は、以下に説明する部分を除いては、上述した実施の形態１または実施の形態２と同様であるものとする。 Embodiment 3 FIG.
A third embodiment of the present invention will be described with reference to FIG. FIG. 12 is a view of the same mode as FIG. 4 regarding the third embodiment of the present invention. The third embodiment is the same as the first embodiment or the second embodiment described above except for the parts described below.
　第１流体１１は、図３から分かるように、仕切りプレート５の隣の第１伝熱プレートの上部、仕切りプレート５の隣の第１伝熱プレートの下部、仕切りプレート５の隣の第２伝熱プレート４ａの下部、仕切りプレート５の隣の第２伝熱プレート４ａの上部の順に温度変化が進行する。よって、仕切りプレート５の表裏関係でみた流体の温度差に関しては、仕切りプレート５の隣の第１伝熱プレートの上部の第１流体１１と、仕切りプレート５の隣の第２伝熱プレート４ａの上部の第１流体１１との温度差が大きい。 As can be seen from FIG. 3, the first fluid 11 includes the upper part of the first heat transfer plate next to the partition plate 5, the lower part of the first heat transfer plate next to the partition plate 5, and the second heat transfer next to the partition plate 5. The temperature change proceeds in the order of the lower part of the heat plate 4 a and the upper part of the second heat transfer plate 4 a adjacent to the partition plate 5. Therefore, regarding the temperature difference of the fluid as seen from the front and back of the partition plate 5, the first fluid 11 at the top of the first heat transfer plate adjacent to the partition plate 5 and the second heat transfer plate 4 a adjacent to the partition plate 5 The temperature difference from the upper first fluid 11 is large.
　これに鑑みて、本実施の形態３では、仕切りプレート５の隣の第１伝熱プレート３０３ｄは、第１凹凸部と仕切りプレート５との当接合計面積が、単位面積当たりでみて、仕切りプレート５の表裏関係でみた流体の温度差が大きい部分ほど、小さくなるような第１凹凸部が形成されている。 In view of this, in the third embodiment, the first heat transfer plate 303d adjacent to the partition plate 5 has a total contact area between the first uneven portion and the partition plate 5 per unit area. The first uneven portion is formed so as to become smaller as the temperature difference of the fluid viewed from the front-back relationship of 5 increases.
　図１２に示す具体的一例では、第１凹凸部３３１ａは、第１凹凸部３１ａ、２３１ａと同様、Ｖ字状に延びる。第１凹凸部３３１ａは、上述したように仕切りプレート５の表裏関係でみた流体の温度差が大きい部分である、仕切りプレート５の隣の第１伝熱プレート３０３ｄの上部側ほど、Ｖ字の山部（谷部）のピッチが広くなっている。言い換えると、仕切りプレート５の隣の第１伝熱プレート３０３ｄの上部の第１凹凸部３３１ａのピッチは、仕切りプレート５の隣の第１伝熱プレート３０３ｄの下部の第１凹凸部３３１ａのピッチよりも大きい。つまりは、上述したように仕切りプレート５の表裏関係でみた流体の温度差が大きい部分である、仕切りプレート５の隣の第１伝熱プレート３０３ｄの上部側ほど、第１凹凸部３３１ａと仕切りプレート５との当接合計面積が、単位面積当たりでみて、小さくなっている。上記以外については、第１凹凸部３３１ａは、第１凹凸部３１ａまたは第１凹凸部２３１ａと同様であるものとする。なお、本実施の形態３は、仕切りプレート５の隣の第２伝熱プレートの第２凹凸部に関して、仕切りプレート５の表裏関係でみた流体の温度差に応じて第１凹凸部３３１ａと仕切りプレート５との当接合計面積を変更するように実施することもできる。 In the specific example shown in FIG. 12, the 1st uneven part 331a is extended in V shape similarly to the 1st uneven part 31a, 231a. As described above, the first concavo-convex portion 331a is a portion where the temperature difference of the fluid as viewed from the front and back of the partition plate 5 is large, and the upper side of the first heat transfer plate 303d adjacent to the partition plate 5 is a V-shaped peak. The pitch of the part (valley part) is wide. In other words, the pitch of the first uneven portion 331a on the upper side of the first heat transfer plate 303d adjacent to the partition plate 5 is larger than the pitch of the first uneven portion 331a on the lower side of the first heat transfer plate 303d adjacent to the partition plate 5. Is also big. In other words, as described above, the first uneven portion 331a and the partition plate are closer to the upper side of the first heat transfer plate 303d adjacent to the partition plate 5, which is a portion where the temperature difference of the fluid as viewed from the front and back of the partition plate 5 is large. The total contact area with 5 is smaller per unit area. Except for the above, the first uneven portion 331a is the same as the first uneven portion 31a or the first uneven portion 231a. In the third embodiment, regarding the second concavo-convex part of the second heat transfer plate adjacent to the partition plate 5, the first concavo-convex part 331a and the partition plate according to the temperature difference of the fluid as viewed from the front and back of the partition plate 5. The total contact area with 5 can also be changed.
　上述した実施の形態３によれば、実施の形態１または実施の形態２で得られる作用効果が同様に得られる。さらに加えて、本実施の形態３では、仕切りプレート５の表裏関係でみた流体の温度差が大きい領域では、望ましくない熱交換を積極的に抑制し、第１熱交換ユニット１と第２熱交換ユニット２との間での熱交換を低減することができる。さらに、仕切りプレート５の表裏関係でみた流体の温度差が小さい領域では、熱交換の抑制作用を積極的に減らすと共に、耐圧強度を積極的に向上させることができる。このように本実施の形態３では、望ましくない熱交換の抑制と、耐圧強度の向上との双方を促進することができる。 According to the third embodiment described above, the operational effects obtained in the first embodiment or the second embodiment can be obtained similarly. In addition, in the third embodiment, in a region where the temperature difference of the fluid as viewed from the front and back of the partition plate 5 is large, undesirable heat exchange is positively suppressed, and the first heat exchange unit 1 and the second heat exchange are suppressed. Heat exchange with the unit 2 can be reduced. Furthermore, in the region where the temperature difference between the fluids in the relationship between the front and back surfaces of the partition plate 5 is small, it is possible to actively reduce the heat exchange suppressing action and to positively improve the pressure resistance. As described above, in the third embodiment, it is possible to promote both suppression of undesirable heat exchange and improvement of pressure strength.
　実施の形態４．
　本発明の実施の形態４について、図１３を用いて説明する。図１３は、本発明の実施の形態４に関し、凹凸部に設けられた陥没部を示す模式部である。なお、本実施の形態４は、以下に説明する部分を除いては、上述した実施の形態１、２または３と同様であるものとする。 Embodiment 4 FIG.
Embodiment 4 of the present invention will be described with reference to FIG. FIG. 13 is a schematic view showing a depressed portion provided in the concavo-convex portion in the fourth embodiment of the present invention. The fourth embodiment is the same as the first, second, or third embodiment described above except for the parts described below.
　本実施の形態４では、仕切りプレートの隣の第１伝熱プレートの第１凹凸部４３１ａと、仕切りプレートの隣の第２伝熱プレートの第２凹凸部４３１ｂとのそれぞれにおいて、陥没部４４１が設けられている。第１凹凸部４３１ａの陥没部４４１は、第１凹凸部４３１ａにおける、仕切りプレート５と対面している側の山部に設けられている。また、第２凹凸部４３１ｂの陥没部４４１は、第２凹凸部４３１ｂにおける、仕切りプレート５と対面している側の山部に設けられている。第１凹凸部４３１ａの陥没部４４１および第２凹凸部４３１ｂの陥没部４４１はともに、積層方向に投影的にみて、第１凹凸部４３１ａと第２凹凸部４３１ｂとの交差点に位置している。言い換えると、第１畝部は第１稜線上に陥没部を有しており、第２畝部は第２稜線上に陥没部を有しており、第１畝部の陥没部および第２畝部の前記陥没部はともに、積層方向に投影的にみて、第１稜線と第２稜線との交差点に位置している。 In the fourth embodiment, in each of the first uneven portion 431a of the first heat transfer plate adjacent to the partition plate and the second uneven portion 431b of the second heat transfer plate adjacent to the partition plate, the depressed portion 441 is provided. Is provided. The depressed portion 441 of the first concavo-convex portion 431a is provided in a mountain portion on the side facing the partition plate 5 in the first concavo-convex portion 431a. In addition, the depressed portion 441 of the second uneven portion 431b is provided at a peak portion on the side facing the partition plate 5 in the second uneven portion 431b. Both the depressed portion 441 of the first uneven portion 431a and the depressed portion 441 of the second uneven portion 431b are located at the intersection of the first uneven portion 431a and the second uneven portion 431b in a projection direction in the stacking direction. In other words, the first collar has a depression on the first ridgeline, the second collar has a depression on the second ridgeline, the depression of the first collar and the second collar Both of the depressed portions of the portion are located at the intersection of the first ridge line and the second ridge line as seen in a projection direction in the stacking direction.
　また、本実施の形態４では、上記実施の形態１～３と同様、第１凹凸部４３１ａの第１方向と、第２凹凸部４３１ｂの第２方向とが、プレートの積層方向に投影的にみて、交差している。したがって、一例であるが、陥没部４４１は次のようにして形成することができる。製造の際に、完成に向けた積層工程の前に、仕切りプレートの隣の第１伝熱プレートと、仕切りプレートの隣の第２伝熱プレートとを、仕切りプレート５を介在させることなく、積層し、所定の荷重をかける。このとき、上記のように第１方向と第２方向とが交差している関係から、第１凹凸部４３１ａの山部と、第２凹凸部４３１ｂの山部とが交差した関係で互いに押し合う。これにより、第１凹凸部４３１ａの山部と、第２凹凸部４３１ｂの山部とが互いに陥没し、第１凹凸部４３１ａの山部と、第２凹凸部４３１ｂの山部との双方に陥没部４４１が形成される。 Further, in the fourth embodiment, similarly to the first to third embodiments, the first direction of the first uneven portion 431a and the second direction of the second uneven portion 431b are projected in the plate stacking direction. Look, cross. Therefore, as an example, the depressed portion 441 can be formed as follows. During the production, before the lamination process for completion, the first heat transfer plate next to the partition plate and the second heat transfer plate next to the partition plate are laminated without interposing the partition plate 5. And apply a predetermined load. At this time, from the relationship in which the first direction and the second direction intersect as described above, the ridges of the first uneven portion 431a and the ridge portions of the second uneven portion 431b are pressed against each other. . As a result, the peak portion of the first uneven portion 431a and the peak portion of the second uneven portion 431b are depressed, and the peak portion of the first uneven portion 431a and the peak portion of the second uneven portion 431b are depressed. A portion 441 is formed.
　上述した実施の形態４によれば、実施の形態１、２または３で得られる作用効果が同様に得られる。また、本実施の形態４では、仕切りプレート５と対面している側の山部に、陥没部があるので、仕切りプレート５と対面している側の山部の陥没部がある部分は、仕切りプレート５と当接せず離隔することができる。よって、本実施の形態４では、山の稜線全体が、仕切りプレート５と当接している場合と比べ、望ましくない熱交換の抑制を図る効果が高い。 According to the above-described fourth embodiment, the operational effects obtained in the first, second, or third embodiment can be obtained in the same manner. Further, in the fourth embodiment, since there is a depressed portion in the mountain portion facing the partition plate 5, the portion having the depressed portion on the mountain portion facing the partition plate 5 is divided into partitions. It can be separated without contacting the plate 5. Therefore, in this Embodiment 4, compared with the case where the whole ridgeline of a mountain is contact | abutting with the partition plate 5, the effect which aims at suppression of the undesirable heat exchange is high.
