Description

本発明は、伝熱管に設けられている側板を備えた熱交換器に関する。 The present invention relates to a heat exchanger having a side plate provided in the heat transfer tube.

従来の空気調和装置の熱交換器には、板状のフィンと、フィンに挿入されている複数の伝熱管と、耐食層が形成されている側板とを備えているものが提案されている（例えば、特許文献１参照）。特許文献１の熱交換器の側板には伝熱管が挿入される円形の開口部が形成されている。ここで、特許文献１の熱交換器の各伝熱管は、フィンが挿入されている直線状の第１の管部と、フィンが挿入され、第１の管部に平行な第２の管部と、曲げ形成され、第１の管部と第２の管部とに接続されている第３の管部とを含んでいる。そして、第１の管部及び第２の管部は、曲げ形成されたベント管に接合される。 A heat exchanger of a conventional air conditioner has been proposed to be provided with plate-shaped fins, a plurality of heat transfer tubes inserted into the fins, and a side plate on which a corrosion-resistant layer is formed. For example, see Patent Document 1). The side plate of the heat exchanger of Patent Document 1 is formed with a circular opening into which a heat transfer tube is inserted. Here, each heat transfer tube of the heat exchanger of Patent Document 1 has a linear first tube portion into which fins are inserted and a second tube portion into which fins are inserted and parallel to the first tube portion. And a third tube portion that is bent and connected to the first tube portion and the second tube portion. Then, the first pipe portion and the second pipe portion are joined to the bent-formed bent pipe.

特許文献１の熱交換器を製造する工程では、伝熱管をフィンに挿入する第１工程の後に、伝熱管を側板の開口部に挿入する第２工程が行われる。そして、特許文献１の熱交換器を製造する工程では、第２工程の後に、伝熱管とベント管とを接合する第３工程が行われる。 In the step of manufacturing the heat exchanger of Patent Document 1, after the first step of inserting the heat transfer tube into the fin, the second step of inserting the heat transfer tube into the opening of the side plate is performed. Then, in the step of manufacturing the heat exchanger of Patent Document 1, after the second step, a third step of joining the heat transfer tube and the vent tube is performed.

国際公開第２０１３／０８４３９７号International Publication No. 2013/08437

特許文献１の熱交換器の側板の伝熱管の挿入部は開口部であるため、第２工程の後に第３の工程が行われる。作業者は、第２工程及び第３の工程の順番を逆にする、すなわち第２の工程の前に第３工程を行う、ことはできない。作業者が第２工程及び第３工程の順番を逆にしてしまうと、ベント管と側板とが干渉することになるので、作業者は、伝熱管を側板の開口部に挿入することができなくなってしまう。 Since the insertion portion of the heat transfer tube on the side plate of the heat exchanger of Patent Document 1 is an opening, a third step is performed after the second step. The operator cannot reverse the order of the second step and the third step, that is, perform the third step before the second step. If the operator reverses the order of the second step and the third step, the vent pipe and the side plate interfere with each other, so that the operator cannot insert the heat transfer pipe into the opening of the side plate. It ends up.

ここで、特許文献１の熱交換器の製造工程のように第２工程の後に第３の工程が行われると、側板は第３の工程で用いられるトーチの炎で熱せられてしまう。これにより、側板の耐食層が溶けて側板の耐食層の一部が薄くなり、側板の耐食性が低下してしまうことがある。また、側板の耐食層が溶けて側板の鉄材が露出してしまい、側板の耐食性が低下してしまうこともある。つまり、特許文献１の熱交換器の側板は、伝熱管とベント管とを接合する第３工程によって、耐食性が低下している場合がある。 Here, if the third step is performed after the second step as in the manufacturing step of the heat exchanger of Patent Document 1, the side plate is heated by the flame of the torch used in the third step. As a result, the corrosion-resistant layer of the side plate may be melted and a part of the corrosion-resistant layer of the side plate may be thinned, resulting in a decrease in the corrosion resistance of the side plate. Further, the corrosion-resistant layer of the side plate may be melted and the iron material of the side plate may be exposed, so that the corrosion resistance of the side plate may be lowered. That is, the side plate of the heat exchanger of Patent Document 1 may have a reduced corrosion resistance due to the third step of joining the heat transfer tube and the vent tube.

本発明は、上記のような課題を解決するためになされたもので、側板の耐食性の低下が抑制されている熱交換器を提供することを目的としている。 The present invention has been made to solve the above problems, and an object of the present invention is to provide a heat exchanger in which a decrease in corrosion resistance of a side plate is suppressed.

本発明に係る熱交換器は、板状のフィンと、第１端部を含み、前記フィンに挿入されている第１伝熱管と、第２端部を含み、前記フィンに挿入され、前記第１伝熱管に平行な第２伝熱管と、前記第１端部及び前記第２端部に設けられ、耐食層が形成されている側板と、一端が前記第１端部に接合され、他端が前記第２端部に接合されているベント管と、を備え、前記側板は、第１側板と前記第１側板に固定されている第２側板とを含み、前記側板には、前記第１側板と前記第２側板との間に設けられ、前記第１端部が挿入されている第１開放部と、前記第１側板と前記第２側板との間に設けられ、前記第２端部が挿入されている第２開放部と、が形成されており、前記第１側板は、前記第１側板の長手方向の一端部である第１側板端部と、前記第１側板の長手方向の他端部である第２側板端部とを含み、前記第２側板は、前記第２側板の長手方向の一端部である第３側板端部と、前記第２側板の長手方向の他端部である第４側板端部とを含み、前記第１側板と前記第２側板とを固定する固定部材を更に備え、前記第３側板端部は前記第１側板端部に固定されており、前記第４側板端部は前記第２側板端部に固定されており、前記第１側板端部には、前記固定部材が挿入される第１孔部が形成され、前記第２側板端部には、開口している爪挿入部が形成され、前記第３側板端部には、前記第１孔部と重ね合わされており、前記固定部材が挿入される第２孔部が形成され、前記第４側板端部には、前記爪挿入部に挿入されている爪部が形成されている。 The heat exchanger according to the present invention includes a plate-shaped fin, a first end portion, a first heat transfer tube inserted into the fin, and a second end portion, and is inserted into the fin and the first portion. A second heat transfer tube parallel to the first heat transfer tube, a side plate provided at the first end portion and the second end portion on which a corrosion resistant layer is formed, and one end joined to the first end portion and the other end. The side plate includes a first side plate and a second side plate fixed to the first side plate, and the side plate includes the first side plate, which is provided with a vent pipe joined to the second end portion. The first open portion provided between the side plate and the second side plate into which the first end portion is inserted, and the second end portion provided between the first side plate and the second side plate. Is formed, and the first side plate is formed with a first side plate end portion which is one end portion in the longitudinal direction of the first side plate and a longitudinal portion of the first side plate. The second side plate includes a second side plate end portion which is the other end portion, and the second side plate includes a third side plate end portion which is one end portion in the longitudinal direction of the second side plate and the other end portion in the longitudinal direction of the second side plate. The third side plate end is further provided with a fixing member for fixing the first side plate and the second side plate, and the third side plate end is fixed to the first side plate end. The fourth side plate end portion is fixed to the second side plate end portion, a first hole portion into which the fixing member is inserted is formed in the first side plate end portion, and the second side plate end portion is formed. , An open claw insertion portion is formed, and a second hole portion which is overlapped with the first hole portion and into which the fixing member is inserted is formed at the third side plate end portion, and the fourth hole portion is formed. A claw portion inserted into the claw insertion portion is formed at the end portion of the side plate .

本発明に係る熱交換器によれば、側板は、第１側板と、第１側板とは別部材である第２側板とを含み、また、第１側板と第２側板との間には、第１端部が挿入される第１開放部と、第２端部が挿入される第２開放部とが形成されている。このため、第１伝熱管の接合及び第２伝熱管の接合の後に、作業者は、第１側板と第２側板とを組み合わせて第１開放部及び第２開放部を形成し、側板を第１伝熱管の第１端部及び第２伝熱管の第２端部に設けることができる。したがって、側板は第１伝熱管の接合のときの炎及び第２伝熱管の接合のときにおける炎で熱せられることが回避され、その結果、本発明に係る熱交換器の側板の耐食性の低下が抑制されている。 According to the heat exchanger according to the present invention, the side plate includes a first side plate and a second side plate which is a member different from the first side plate, and between the first side plate and the second side plate, A first open portion into which the first end portion is inserted and a second open portion into which the second end portion is inserted are formed. Therefore, after joining the first heat transfer tube and the second heat transfer tube, the operator combines the first side plate and the second side plate to form the first open portion and the second open portion, and the side plate is used as the first side plate. 1 It can be provided at the first end of the heat transfer tube and the second end of the second heat transfer tube. Therefore, it is avoided that the side plate is heated by the flame when the first heat transfer tube is joined and the flame when the second heat transfer tube is joined, and as a result, the corrosion resistance of the side plate of the heat exchanger according to the present invention is lowered. It is suppressed.

第１側板３は、鋼板と、鋼板の表面に形成され、鋼板の腐食を抑制する耐食層とを備えている。側板ＳＢの耐食層は、鋼板を溶融亜鉛でめっきすることで形成された層である。つまり、側板ＳＢの耐食層は亜鉛で構成される。ここで、側板ＳＢの耐食層が亜鉛で構成されることに限定されるものではない。側板ＳＢの鋼板をめっきする材料には、亜鉛、アルミニウム、マグネシウム及びシリコンを含む金属混合材料を採用することができる。この場合には、側板ＳＢの耐食層はこの金属混合材料で構成される。亜鉛、アルミニウム、マグネシウム及びシリコンを含む金属混合材料の耐食層は、亜鉛の耐食層よりも、耐食性が高い。また、側板ＳＢの鋼板の材料にはステンレス鋼板を採用することができる。側板ＳＢの鋼板としてステンレス鋼板を採用した場合において、鋼板の表面には酸化皮膜である不動態皮膜が形成される。このため、側板ＳＢの鋼板としてステンレス鋼板を採用した場合において、側板ＳＢの耐食層は不動態皮膜で構成される。ステンレス鋼板の耐食層の耐食性は、亜鉛の耐食層の耐食性よりも高く、また、ステンレス鋼板の耐食層の耐食性は、亜鉛、アルミニウム、マグネシウム及びシリコンを含む金属混合材料の耐食層の耐食性よりも高い。 The first side plate 3 includes a steel plate and a corrosion-resistant layer formed on the surface of the steel plate and suppressing corrosion of the steel plate. The corrosion-resistant layer of the side plate SB is a layer formed by plating a steel plate with hot-dip zinc. That is, the corrosion-resistant layer of the side plate SB is composed of zinc. Here, the corrosion-resistant layer of the side plate SB is not limited to being composed of zinc. As a material for plating the steel plate of the side plate SB, a metal mixed material containing zinc, aluminum, magnesium and silicon can be adopted. In this case, the corrosion resistant layer of the side plate SB is made of this metal mixed material. The corrosion-resistant layer of the metal mixed material containing zinc, aluminum, magnesium and silicon has higher corrosion resistance than the corrosion-resistant layer of zinc. Further, a stainless steel plate can be adopted as the material of the steel plate of the side plate SB. When a stainless steel plate is used as the steel plate of the side plate SB, a passivation film, which is an oxide film, is formed on the surface of the steel plate. Therefore, when a stainless steel plate is used as the steel plate of the side plate SB, the corrosion-resistant layer of the side plate SB is composed of a passivation film. The corrosion resistance of the corrosion-resistant layer of the stainless steel plate is higher than the corrosion resistance of the corrosion-resistant layer of zinc, and the corrosion resistance of the corrosion-resistant layer of the stainless steel plate is higher than the corrosion resistance of the corrosion-resistant layer of the metal mixture containing zinc, aluminum, magnesium and silicon. ..

The first side plate 3 includes a first side plate end portion t1 which is one end portion of the first side plate 3 in the longitudinal direction Dr1 and a second side plate end portion t2 which is the other end portion of the first side plate 3 in the longitudinal direction Dr1. ..

The longitudinal direction Dr1 and the longitudinal direction Dr2 are parallel. The second side plate 4 is also a plate material formed in a comb-teeth shape like the first side plate 3. Specifically, the second side plate 4 is formed with a plurality of notches 4A into which the heat transfer tube 2 is inserted. A second hole 4B into which the fixing member 5 is inserted is formed in the third side plate end portion t3.

The second side plate 4 is provided between the first side plate 3 and the fins 1 arranged on the second side plate 4 side of the plurality of fins 1. Here, the open portion Op shown in FIGS. 4A and 4B is formed by combining the notch 3A of the first side plate 3 and the notch 4A of the second side plate 4. That is, the open portion Op is formed by the notch portion 3A of the first side plate 3 and the notch portion 4A of the second side plate 4. The notch 3A into which the first end 2D1 is inserted corresponds to the first notch, and the notch 4A into which the first end 2D1 is inserted corresponds to the third notch. Further, the notch 3A into which the second end 2D2 is inserted corresponds to the second notch, and the notch 4A into which the first end 2D1 is inserted corresponds to the fourth notch.

図６及び図４（ｂ）に示すように、切欠部３Ａは、伝熱管２と接触する縁部３Ａ１と、縁部３Ａ１の一端に繋がっている縁部３Ａ２と、縁部３Ａ１の他端に繋がっており、縁部３Ａ２に平行に延びている縁部３Ａ３とを含んでいる。また、図７及び図４（ｂ）に示すように、切欠部４Ａは、伝熱管２と接触し、縁部３Ａ１に平行に延びている縁部４Ａ１と、縁部４Ａ１の一端に繋がっている縁部４Ａ２と、縁部４Ａ２の他端に繋がっており、縁部４Ａ２に平行に延びている縁部４Ａ３とを含んでいる。図４（ｂ）に示すように、側板ＳＢが第１端部２Ｄ１及び第２端部２Ｄ２に設けられている状態において、第１端部２Ｄ１及び第２端部２Ｄ２は、縁部３Ａ１と縁部４Ａ１とによって挟み込まれている。これにより、第１端部２Ｄ１は縁部３Ａ１及び縁部４Ａ１に接触するとともに、第２端部２Ｄ２は縁部３Ａ１及び縁部４Ａ１に接触することとなり、その結果、側板ＳＢが伝熱管２に固定される。 As shown in FIGS. 6 and 4B, the cutout portion 3A is provided at the edge portion 3A1 in contact with the heat transfer tube 2, the edge portion 3A2 connected to one end of the edge portion 3A1, and the other end of the edge portion 3A1.

It includes an edge portion 4A2 and an edge portion 4A3 which is connected to the other end of the edge portion 4A2 and extends in parallel with the edge portion 4A2. As shown in FIG. 4B, in a state where the side plates SB are provided on the first end portion 2D1 and the second end portion 2D2, the first end portion 2D1 and the second end portion 2D2 are edged with the edge portion 3A1. It is sandwiched by parts 4A1. As a result, the first end portion 2D1 comes into contact with the edge portion 3A1 and the edge portion 4A1, and the second end portion 2D2 comes into contact with the edge portion 3A1 and the edge portion 4A1, and as a result, the side plate SB becomes the heat transfer tube 2. It is fixed.

また、第１端部２Ｄ１は、縁部３Ａ２、縁部３Ａ３、縁部４Ａ２及び縁部４Ａ３に接触していなくてもよいが、第１端部２Ｄ１が縁部３Ａ２、縁部３Ａ３、縁部４Ａ２及び縁部４Ａ３に接触していれば、側板ＳＢと伝熱管２との固定はより強固になる。また、第２端部２Ｄ２は、縁部３Ａ２、縁部３Ａ３、縁部４Ａ２及び縁部４Ａ３に接触していなくてもよいが、第２端部２Ｄ２が縁部３Ａ２、縁部３Ａ３、縁部４Ａ２及び縁部４Ａ３に接触していれば、側板ＳＢと伝熱管２との固定はより強固になる。 Further, the first end portion 2D1 does not have to be in contact with the edge portion 3A2, the edge portion 3A3, the edge portion 4A2 and the edge portion 4A3, but the first end portion 2D1 is the edge portion 3A2, the edge portion 3A3, and the edge portion. If it is in contact with the 4A2 and the edge 4A3, the fixing between the side plate SB and the heat transfer tube 2 becomes stronger. Further, the second end portion 2D2 may not be in contact with the edge portion 3A2, the edge portion 3A3, the edge portion 4A2 and the edge portion 4A3, but the second end portion 2D2 is the edge portion 3A2, the edge portion 3A3, and the edge portion. If it is in contact with the 4A2 and the edge 4A3, the fixing between the side plate SB and the heat transfer tube 2 becomes stronger.

側板ＳＢは、第１側板３と、第１側板３とは別部材である第２側板４とを含む。第１側板３と第２側板４との間には、伝熱管２が挿入される開放部Ｏｐが形成されている。このため、伝熱管２の接合の後に、作業者は、第１側板３と第２側板４とを組み合わせて開放部Ｏｐを形成し、側板ＳＢを伝熱管２に設けることができる。つまり、作業者は、伝熱管２の接合の前に、側板ＳＢを伝熱管２に設ける必要がない。したがって、側板ＳＢは伝熱管２の接合のときのトーチＴＨの炎で熱せられることが回避され、その結果、側板ＳＢの表面の耐食層はトーチＴＨの炎で溶けてしまうことが回避されている。すなわち、側板ＳＢの鋼板に形成されている耐食層が溶けて耐食層が薄くなること、及び、側板ＳＢの鋼板に形成されている耐食層が溶けて鋼板が露出すること、が回避されている。よって、実施の形態１に係る熱交換器１０の側板ＳＢの耐食性の低下は抑制されている。<Effect of Embodiment 1>
The side plate SB includes a first side plate 3 and a second side plate 4 which is a member different from the first side plate 3. An open portion Op into which the heat transfer tube 2 is inserted is formed between the first side plate 3 and the second side plate 4. Therefore, after joining the heat transfer tubes 2, the operator can combine the first side plate 3 and the second side plate 4 to form an open portion Op, and provide the side plate SB on the heat transfer tube 2. That is, the operator does not need to provide the side plate SB on the heat transfer tube 2 before joining the heat transfer tube 2. Therefore, it is avoided that the side plate SB is heated by the flame of the torch TH when the heat transfer tube 2 is joined, and as a result, the corrosion-resistant layer on the surface of the side plate SB is prevented from being melted by the flame of the torch TH. .. That is, it is avoided that the corrosion-resistant layer formed on the steel plate of the side plate SB melts and the corrosion-resistant layer becomes thin, and that the corrosion-resistant layer formed on the steel plate of the side plate SB melts and the steel plate is exposed. .. Therefore, the deterioration of the corrosion resistance of the side plate SB of the heat exchanger 10 according to the first embodiment is suppressed.

第１側板３と第２側板４とは重ねられている。つまり、第１側板３と第２側板４とが重ねられた状態で、第１側板３と第２側板４とは固定されている。このため、第１側板３と第２側板４とが重なる部分において、側板ＳＢは厚みが増している。したがって、第１側板３と第２側板４とが重なる部分において、側板ＳＢの剛性が向上する。 The first side plate 3 and the second side plate 4 are overlapped with each other. That is, the first side plate 3 and the second side plate 4 are fixed in a state where the first side plate 3 and the second side plate 4 are overlapped with each other. Therefore, the thickness of the side plate SB is increased at the portion where the first side plate 3 and the second side plate 4 overlap. Therefore, the rigidity of the side plate SB is improved at the portion where the first side plate 3 and the second side plate 4 overlap.

第２側板４の第３側板端部ｔ３は第１側板３の第１側板端部ｔ１に固定されており、且つ、第２側板４の第４側板端部ｔ４は第１側板３の第２側板端部ｔ２に固定されている。つまり、側板ＳＢの長手方向の端部が、第１側板３と第２側板４との固定部になっている。側板ＳＢの長手方向の例えば中央部が第１側板３と第２側板４との固定部になっている場合を考える。この場合において、例えば第１側板端部ｔ１に第３側板端部ｔ３から離れる方向に力が加わったとすると、固定部まわりの力のモーメントは、第１側板端部ｔ１と固定部との距離が離れている分、大きくなってしまう。このため、第１側板３は、第１側板端部ｔ１に第３側板端部ｔ３から離れる方向に力が加わったときに変形しやすくなってしまう。第２側板端部ｔ２についても同様であり、第１側板３は、第２側板端部ｔ２に第４側板端部ｔ４から離れる方向に力が加わったときに変形しやすくなってしまう。また、第３側板端部ｔ３及び第４側板端部ｔ４についても同様である。つまり、第２側板４は、第３側板端部ｔ３に第１側板端部ｔ１から離れる方向に力が加わったときに変形しやすくなってしまい、第２側板４は、第４側板端部ｔ４に第２側板端部ｔ２から離れる方向に力が加わったときに変形しやすくなってしまう。しかし、実施の形態１において、側板ＳＢの長手方向の端部が、第１側板３と第２側板４との固定部になっている。したがって、側板ＳＢは固定部まわりの力のモーメントが大きくなることを抑制することができ、側板ＳＢは変形しにくくなっている。 The third side plate end portion t3 of the second side plate 4 is fixed to the first side plate end portion t1 of the first side plate 3, and the fourth side plate end portion t4 of the second side plate 4 is the second side plate 3 of the first side plate 3. It is fixed to the side plate end portion t2. That is, the end portion in the longitudinal direction of the side plate SB is a fixing portion between the first side plate 3 and the second side plate 4. Consider a case where, for example, the central portion in the longitudinal direction of the side plate SB is a fixing portion between the first side plate 3 and the second side plate 4. In this case, for example, if a force is applied to the first side plate end portion t1 in a direction away from the third side plate end portion t3, the moment of force around the fixed portion is the distance between the first side plate end portion t1 and the fixed portion. The farther it is, the bigger it gets. Therefore, the first side plate 3 is likely to be deformed when a force is applied to the first side plate end portion t1 in a direction away from the third side plate end portion t3. The same applies to the second side plate end portion t2, and the first side plate 3 tends to be deformed when a force is applied to the second side plate end portion t2 in a direction away from the fourth side plate end portion t4. The same applies to the third side plate end portion t3 and the fourth side plate end portion t4. That is, the second side plate 4 is easily deformed when a force is applied to the third side plate end portion t3 in the direction away from the first side plate end portion t1, and the second side plate 4 is easily deformed when the force is applied to the third side plate end portion t3. When a force is applied in the direction away from the second side plate end portion t2, the deformation tends to occur. However, in the first embodiment, the end portion in the longitudinal direction of the side plate SB is a fixing portion between the first side plate 3 and the second side plate 4. Therefore, the side plate SB can suppress an increase in the moment of force around the fixed portion, and the side plate SB is less likely to be deformed.

第２側板４の第３側板端部ｔ３は第１側板３の第１側板端部ｔ１に固定されており、且つ、第２側板４の第４側板端部ｔ４は第１側板３の第２側板端部ｔ２に固定されている。つまり、側板ＳＢは、第１側板３と第２側板４との固定部が複数設けられている。したがって、第２側板４が第１側板３に対して回転してしまい、第２側板４の位置がずれてしまうことを回避することができる。逆に、第１側板３が第２側板４に対して回転してしまい、第１側板３の位置がずれてしまうことを回避することができる。 The third side plate end portion t3 of the second side plate 4 is fixed to the first side plate end portion t1 of the first side plate 3, and the fourth side plate end portion t4 of the second side plate 4 is the second side plate 3 of the first side plate 3. It is fixed to the side plate end portion t2. That is, the side plate SB is provided with a plurality of fixing portions between the first side plate 3 and the second side plate 4. Therefore, it is possible to prevent the second side plate 4 from rotating with respect to the first side plate 3 and the position of the second side plate 4 from shifting. On the contrary, it is possible to prevent the first side plate 3 from rotating with respect to the second side plate 4 and the position of the first side plate 3 being displaced.

熱交換器１０は第１側板３と第２側板４とを固定する固定部材５を備えているので、側板ＳＢは、第１側板３と第２側板４との固定が強固になっている。また、第１側板３の第１側板端部ｔ１には爪挿入部３Ｃが形成され、第２側板４の第４側板端部ｔ４には爪部４Ｃが形成されている。このため、作業者が爪部４Ｃを爪挿入部３Ｃへ挿入する作業をすることで、作業者は第１側板３と第２側板４とを組み合わせることができる。つまり、作業者は、例えばネジを第１側板３と第２側板４に挿入するといった煩雑な作業をしなくても、作業者は、第１側板３と第２側板４とを組み合わせることができる。これにより、第１側板３と第２側板４とを組み合わせるときにおける作業負担が抑制される。 Since the heat exchanger 10 includes a fixing member 5 for fixing the first side plate 3 and the second side plate 4, the side plate SB is firmly fixed to the first side plate 3 and the second side plate 4. Further, a claw insertion portion 3C is formed at the first side plate end portion t1 of the first side plate 3, and a claw portion 4C is formed at the fourth side plate end portion t4 of the second side plate 4. Therefore, when the worker inserts the claw portion 4C into the claw insertion portion 3C, the worker can combine the first side plate 3 and the second side plate 4. That is, the operator can combine the first side plate 3 and the second side plate 4 without having to perform complicated work such as inserting screws into the first side plate 3 and the second side plate 4. .. As a result, the work load when the first side plate 3 and the second side plate 4 are combined is suppressed.

第１側板３は切欠部３Ａを含み、第２側板４は切欠部４Ａを含み、開放部Ｏｐは切欠部３Ａと切欠部４Ａとにより形成されている。つまり、作業者が第１側板３と第２側板４とが組み合わせることで、作業者は側板ＳＢを伝熱管２に設けることができる。ここで、第１側板３と第２側板４とを組み合わせる作業は、作業者が第１側板３の切欠部３Ａを伝熱管２に挿入する作業をし、且つ、作業者が第２側板４の切欠部４Ａを伝熱管２に挿入する作業をすることで実現することができる。作業者が第１側板３の切欠部３Ａを伝熱管２に挿入する作業、及び、作業者が第２側板４の切欠部４Ａを伝熱管２に挿入する作業は、伝熱管２とベント管２Ｃとの接合後であっても、行うことができる。なぜなら、図１２に示すように、作業者は、第１側板３の切欠部３Ａを伝熱管２に差し込むことができるとともに、第２側板４の切欠部４Ａを伝熱管２に差し込むことができるためである。このため、伝熱管２とベント管２Ｃとの接合後であっても、作業者は第１側板３と第２側板４とを組み合わせることができる。これにより、側板ＳＢは伝熱管２の接合のときのトーチＴＨの炎で熱せられることが回避され、その結果、側板ＳＢの表面の耐食層はトーチの炎で溶けてしまうことが回避されている。したがって、熱交換器１０の側板ＳＢの耐食性の低下は抑制されている。 The first side plate 3 includes a notch 3A, the second side plate 4 includes a notch 4A, and the open portion Op is formed by the notch 3A and the notch 4A. That is, when the operator combines the first side plate 3 and the second side plate 4, the operator can provide the side plate SB on the heat transfer tube 2. Here, in the work of combining the first side plate 3 and the second side plate 4, the worker inserts the notch 3A of the first side plate 3 into the heat transfer tube 2, and the worker inserts the notch 3A of the first side plate 3 into the heat transfer tube 2. This can be achieved by inserting the notch 4A into the heat transfer tube 2. The work of the worker inserting the notch 3A of the first side plate 3 into the heat transfer tube 2 and the work of the worker inserting the notch 4A of the second side plate 4 into the heat transfer tube 2 are the heat transfer tube 2 and the vent tube 2C. It can be done even after joining with. This is because, as shown in FIG. 12, the operator can insert the notch 3A of the first side plate 3 into the heat transfer tube 2 and insert the notch 4A of the second side plate 4 into the heat transfer tube 2. Is. Therefore, even after the heat transfer pipe 2 and the vent pipe 2C are joined, the operator can combine the first side plate 3 and the second side plate 4. As a result, the side plate SB is prevented from being heated by the flame of the torch TH when the heat transfer tube 2 is joined, and as a result, the corrosion-resistant layer on the surface of the side plate SB is prevented from being melted by the flame of the torch. .. Therefore, the deterioration of the corrosion resistance of the side plate SB of the heat exchanger 10 is suppressed.

実施の形態１において、熱交換器１０は固定部材５を備えた構成であったが、この構成に限定されるものではない。第１側板３と第２側板４とは接着剤で固定されていてもよい。これにより、熱交換器１０が固定部材５を備えない分、熱交換器１０の材料コストが低減される。 In the first embodiment, the heat exchanger 10 has a configuration including the fixing member 5, but the heat exchanger 10 is not limited to this configuration. The first side plate 3 and the second side plate 4 may be fixed with an adhesive. As a result, the material cost of the heat exchanger 10 is reduced because the heat exchanger 10 does not include the fixing member 5.

図１７は実施の形態１の変形例１に係る第１側板３ｔ１を示す図である。図１８は実施の形態１の変形例１に係る第２側板４ｔ１を示す図である。第１側板３ｔ１の切欠部３Ａｔは、円管である伝熱管の周面に沿っている、すなわち円弧状になっている縁部３Ａｔ１を有している。また、第２側板４ｔ１の切欠部４Ａｔは、円管である伝熱管の周面に沿っている、すなわち円弧状になっている縁部４Ａｔ１を有している。縁部３Ａｔ１及び縁部４Ａｔ１が共に円弧状になっているため、縁部３Ａｔ１と縁部４Ａｔ１とを組み合わせた形状、すなわち開放部の形状は円形状になる。 FIG. 17 is a diagram showing a first side plate 3t1 according to a modification 1 of the first embodiment. FIG. 18 is a diagram showing a second side plate 4t1 according to a modification 1 of the first embodiment. The cutout portion 3At of the first side plate 3t1 has an edge portion 3At1 that is along the peripheral surface of the heat transfer tube that is a circular tube, that is, has an arc shape. Further, the cutout portion 4At of the second side plate 4t1 has an edge portion 4At1 that is along the peripheral surface of the heat transfer tube that is a circular tube, that is, has an arc shape. Since both the edge portion 3At1 and the edge portion 4At1 have an arc shape, the shape of the combination of the edge portion 3At1 and the edge portion 4At1, that is, the shape of the open portion has a circular shape.

変形例１において、切欠部３Ａｔの縁部３Ａｔ１は円管である伝熱管の周面に沿っており、切欠部４Ａｔの縁部４Ａｔ１も円管である伝熱管の周面に沿っている。その結果、縁部３Ａｔ１と縁部４Ａｔ１とを組み合わせた形状、すなわち開放部の形状は円形状になる。このため、伝熱管２の管軸に直交する断面において伝熱管２の管軸を伝熱管２の中心としたとき、伝熱管２の中心における中心角が３６０度の範囲にわたって、伝熱管２と開放部とは接触することになる。つまり、変形例１の構成は、伝熱管２と開放部との接触面積を増大させることができる。これにより、第１側板３ｔ１と伝熱管２との固定、及び、第２側板４ｔ１と伝熱管２との固定が、より強固になる。 In the first modification, the edge portion 3At1 of the notch portion 3At is along the peripheral surface of the heat transfer tube which is a circular tube, and the edge portion 4At1 of the notch portion 4At is also along the peripheral surface of the heat transfer tube which is a circular tube. As a result, the shape of the combination of the edge portion 3At1 and the edge portion 4At1, that is, the shape of the open portion becomes a circular shape. Therefore, when the tube axis of the heat transfer tube 2 is the center of the heat transfer tube 2 in the cross section orthogonal to the tube axis of the heat transfer tube 2, the center angle at the center of the heat transfer tube 2 is open to the heat transfer tube 2 over a range of 360 degrees. It will come into contact with the part. That is, the configuration of the modified example 1 can increase the contact area between the heat transfer tube 2 and the open portion. As a result, the fixing of the first side plate 3t1 and the heat transfer tube 2 and the fixing of the second side plate 4t1 and the heat transfer tube 2 become stronger.

図１９は、実施の形態１の変形例２に係る側板ＳＢｔ２を示す図である。実施の形態１において、第１側板３の第２側板端部ｔ２には爪挿入部３Ｃが形成され、第２側板４の第４側板端部ｔ４には爪部４Ｃが形成されていたが、これらの構成に限定されるものではない。図１９に示すように、第２側板端部ｔ２には固定部材５Ｂが挿入される孔部３Ｂｔ２が形成され、第４側板端部ｔ４には固定部材５Ｂが挿入される孔部４Ｂｔ２が形成されていてもよい。 FIG. 19 is a diagram showing a side plate SBt2 according to a modification 2 of the first embodiment. In the first embodiment, the claw insertion portion 3C is formed at the second side plate end portion t2 of the first side plate 3, and the claw portion 4C is formed at the fourth side plate end portion t4 of the second side plate 4. It is not limited to these configurations. As shown in FIG. 19, a hole 3Bt2 into which the fixing member 5B is inserted is formed in the second side plate end t2, and a hole 4Bt2 into which the fixing member 5B is inserted is formed in the fourth side plate end t4. You may be.

変形例２の構成は、第１側板３と第２側板４とを固定する固定部材５に加えて、第１側板３と第２側板４とを固定する固定部材５Ｂを備えている。これにより、第１側板３と第２側板４との固定は、更に強固になっている。 The configuration of the modified example 2 includes a fixing member 5B for fixing the first side plate 3 and the second side plate 4 in addition to the fixing member 5 for fixing the first side plate 3 and the second side plate 4. As a result, the fixing between the first side plate 3 and the second side plate 4 is further strengthened.
