Description

本発明は、例えば空調装置に用いられる凝縮器等の熱交換器に関する。 The present invention relates to a heat exchanger such as a condenser used in an air conditioner, for example.

従来より、この種の熱交換器として、冷媒の流通する扁平状チューブが厚み方向に複数並べて設けられ、該チューブの長手方向両端に各チューブが連通する中空部を有する円筒状ヘッダタンクがそれぞれ配設され、上記ヘッダタンクの中空部がチューブ並設方向一側と他側とに仕切られた熱交換器が知られている（例えば、特許文献１参照）。このようにヘッダタンクの中空部を仕切ることにより、冷媒流れの上流側から下流側に連なる複数のパスが構成される。これにより、冷媒を熱交換器内で蛇行して流すことが可能になり、熱交換効率が向上する。 Conventionally, as this type of heat exchanger, a plurality of flat tubes through which refrigerant flows are arranged in the thickness direction, and cylindrical header tanks having hollow portions communicating with the tubes at both ends in the longitudinal direction of the tubes are respectively arranged. There is known a heat exchanger in which the hollow portion of the header tank is partitioned into one side and the other side in the tube juxtaposition direction (see, for example, Patent Document 1). By partitioning the hollow portion of the header tank in this way, a plurality of paths that are continuous from the upstream side to the downstream side of the refrigerant flow are configured. As a result, the refrigerant can meander and flow in the heat exchanger, and the heat exchange efficiency is improved.

上記特許文献１の熱交換器では、ヘッダタンクを仕切る構造として、ヘッダタンクの中空部に仕切部材を配設する構造を採っている。すなわち、ヘッダタンクの周壁部には、仕切部材を中空部へ挿入するための仕切部材挿入孔が周方向に延びるスリット形状をなすように形成されている。仕切部材は、第１及び第２板状部を備えている。これら板状部の挿入方向先端側の周縁部同士は連結され、この連結部分が折り曲げられて両板状部が互いに重ね合わされている。上記第１及び第２板状部の周縁部は、ヘッダタンクの内面に沿うように形成されている。 In the heat exchanger of the said patent document 1, the structure which arrange | positions a partition member in the hollow part of a header tank is taken as a structure which partitions off a header tank. That is, a partition member insertion hole for inserting the partition member into the hollow portion is formed in the peripheral wall portion of the header tank so as to form a slit shape extending in the circumferential direction. The partition member includes first and second plate-like portions. The peripheral portions on the leading end side in the insertion direction of these plate-like portions are connected to each other, the connecting portions are bent, and the two plate-like portions are overlapped with each other. The peripheral edge portions of the first and second plate-like portions are formed along the inner surface of the header tank.

第１板状部の挿入方向先端部と基端部との中央部には、両板状部を折り畳んだ状態で基端側を第２板状部から離れるように傾斜させる屈曲部が形成され、また、第２板状部にも同様に屈曲部が形成されている。このため、両板状部を互いに重ね合わせると、先端側が接触する一方、基端側が厚み方向に離れることになる。また、第１及び第２板状部の挿入方向基端側には、ヘッダタンクの中空部に挿入された状態で、仕切部材挿入孔の周縁部に中空部側から係合する突起が形成されている。 A bent portion is formed at the central portion between the distal end portion and the proximal end portion in the insertion direction of the first plate-like portion so that the proximal end side is inclined away from the second plate-like portion in a state where both plate-like portions are folded. In addition, a bent portion is similarly formed in the second plate-like portion. For this reason, when the two plate-like portions are overlapped with each other, the distal end side comes into contact, while the proximal end side is separated in the thickness direction. In addition, on the proximal end side in the insertion direction of the first and second plate-like parts, a protrusion that engages from the hollow part side is formed at the peripheral part of the partition member insertion hole in a state of being inserted into the hollow part of the header tank. ing.

上記第１及び第２板状部を互いに重ね合わせた状態でヘッダタンクの挿入孔から中空部に挿入すると、これら板状部の挿入方向基端側は、屈曲部を境にして互いに離れる方向に傾斜しているので、該板状部の持つ弾性力により基端側が仕切部材挿入孔の周縁部に接する方向に付勢されて圧接するとともに、突起が仕切部材挿入孔の周縁部に係合し、仕切部材がヘッダタンクに組み付けられた状態になる。この状態で、ろう付け用の炉内に搬送されて仕切部材の板状部の周縁部がヘッダタンクの内面にろう付けされ、仕切部材がヘッダタンクに完全に固定された状態になる。
特許第３１７３８３０号公報 When the first and second plate-like portions are overlapped with each other and inserted into the hollow portion from the insertion hole of the header tank, the insertion direction base ends of these plate-like portions are separated from each other with the bent portion as a boundary. Since it is inclined, the elastic force of the plate-like part urges and presses the base end side in a direction in contact with the peripheral edge of the partition member insertion hole, and the protrusion engages with the peripheral edge of the partition member insertion hole. The partition member is assembled in the header tank. In this state, it is transported into a brazing furnace and the peripheral edge of the plate-like portion of the partition member is brazed to the inner surface of the header tank, so that the partition member is completely fixed to the header tank.
Japanese Patent No. 3173830

ところが、特許文献１のように第１及び第２板状部に屈曲部を設けるようにした場合、この屈曲部は、平坦な板状部を折り曲げて形成しているだけなので、平坦な形状に復元し易い。このため、第１及び第２板状部を互いに重ね合わせて仕切部材挿入孔に挿入すると、板状部の基端側の傾斜角度が小さくなるように屈曲部が変形してしまうことが考えられる。こうなると、板状部の基端側の付勢力が弱くなり、該板状部の基端側が挿入孔の周縁部に圧接しなくなるとともに、突起の係合力が低下する。その結果、仕切部材をヘッダタンクに組み付けた状態でろう付け用の炉内に搬送する際に、仕切部材が振動等によって正規の組み付け位置から動いて、板状部の周縁部がヘッダタンクの内面から離れ、ヘッダタンクの仕切部分が連通してしまうという不具合が発生する。 However, when a bent portion is provided in the first and second plate-like portions as in Patent Document 1, the bent portion is formed by bending a flat plate-like portion, so that the flat shape is obtained. Easy to restore. For this reason, when the first and second plate-like portions are overlapped with each other and inserted into the partition member insertion hole, the bent portion may be deformed so that the inclination angle on the base end side of the plate-like portion becomes small. . In this case, the urging force on the base end side of the plate-like portion becomes weak, the base end side of the plate-like portion does not come into pressure contact with the peripheral edge portion of the insertion hole, and the engaging force of the protrusion is reduced. As a result, when the partition member is transported into the brazing furnace in a state where it is assembled to the header tank, the partition member moves from the normal assembly position by vibration or the like, and the peripheral portion of the plate-like portion is the inner surface of the header tank. This causes a problem in that the partition portion of the header tank is in communication.

本発明は斯かる点に鑑みてなされたものであり、その目的とするところは、第１及び第２板状部を互いに重ね合わせてなる仕切部材でヘッダタンクを仕切るようにした熱交換器において、その仕切部材がヘッダタンクに完全に固定されるまでの間に正規の組み付け位置からずれないようにして、ヘッダタンクの仕切部分が連通しないようにすることにある。 This invention is made in view of such a point, The place made into the objective is in the heat exchanger which partitioned off the header tank with the partition member which mutually overlaps the 1st and 2nd plate-shaped part. The partition member of the header tank does not communicate with each other so that the partition member does not deviate from the normal assembly position until the partition member is completely fixed to the header tank.

上記目的を達成するために、本発明では、第１板状部の連結部分よりも挿入方向基端側に突出部を設け、両板状部を互いに重ね合わせた状態で突出部を第２板状部に当てるようにした。 In order to achieve the above object, in the present invention, a protrusion is provided on the proximal side in the insertion direction with respect to the connecting portion of the first plate-like portion, and the protrusion is attached to the second plate in a state where both plate-like portions are overlapped with each other. I tried to hit it.

具体的には、請求項１の発明では、並設された複数のチューブが連通する中空部を有するヘッダタンクと、該ヘッダタンクの周壁部に形成された挿入孔から挿入され、上記中空部をチューブの並設方向一側及び他側に仕切る仕切部材とを備えた熱交換器であって、上記仕切部材は、挿入方向先端側の周縁部の一部分が互いに連結された第１板状部及び第２板状部を備えるとともに、該両板状部が連結部分で折り曲げられて互いに重ね合わされた状態で上記挿入孔から上記中空部に挿入されて配置され、上記第１板状部の連結部分よりも挿入方向基端側には、上記第２板状部側へ突出する第１突出部が設けられている構成とする。 Specifically, in the invention of claim 1, a header tank having a hollow portion through which a plurality of tubes arranged in parallel communicate with each other, and an insertion hole formed in a peripheral wall portion of the header tank, the hollow portion is inserted. A heat exchanger comprising a partition member that partitions the tube in the side-by-side direction and the other side, wherein the partition member includes a first plate-like portion in which a part of peripheral portions on the distal end side in the insertion direction are connected to each other; A second plate-like portion is provided, and the two plate-like portions are bent and joined to each other in a connecting portion and are inserted into the hollow portion from the insertion hole and arranged, and the connecting portion of the first plate-like portion Furthermore, it is set as the structure by which the 1st protrusion part which protrudes to the said 2nd plate-shaped part side is provided in the insertion direction base end side.

この構成によれば、第１及び第２板状部の連結部分を折り曲げて両板状部を互いに重ね合わせると、第１板状部の突出部が第２板状部に当たり、両板状部が突出部により互いに離れた状態となる。このように突出部を当てて両板状部を厚み方向に離すようにすることで、仕切部材をヘッダタンクの挿入孔に挿入した際、従来例の仕切部材のように屈曲部の形状が復元すること起因した板状部の付勢力の低下が起こらず、板状部を挿入孔の周縁部に向けて付勢する付勢力を十分に確保することが可能になる。これにより、第１及び第２板状部をヘッダタンクの挿入孔の周縁部に圧接させることが可能になる。 According to this configuration, when the connecting portion of the first and second plate-like portions is bent and the two plate-like portions are overlapped with each other, the protruding portion of the first plate-like portion hits the second plate-like portion, and both plate-like portions Are separated from each other by the protrusions. In this way, when the partition member is inserted into the insertion hole of the header tank, the shape of the bent portion is restored like the partition member of the conventional example when the projecting portion is applied and the two plate-like portions are separated in the thickness direction. As a result, the urging force of the plate-like portion does not decrease, and the urging force for urging the plate-like portion toward the peripheral portion of the insertion hole can be sufficiently secured. Thereby, it becomes possible to press-contact the 1st and 2nd plate-shaped part to the peripheral part of the insertion hole of a header tank.

請求項２の発明では、請求項１の発明において、第１及び第２板状部の少なくとも一方には、該両板状部を互いに重ね合わせた状態で一方の板状部の挿入方向基端側を他方の板状部から離れるように傾斜させる屈曲部が設けられ、第１突出部は、上記屈曲部に対応する部位に設けられている構成とする。 According to a second aspect of the present invention, in the first aspect of the invention, at least one of the first and second plate-like portions has a base end in the insertion direction of one plate-like portion in a state where the two plate-like portions are overlapped with each other. A bent portion that inclines the side away from the other plate-like portion is provided, and the first projecting portion is provided at a portion corresponding to the bent portion.

この構成によれば、第１及び第２板状部を互いに重ね合わせて挿入孔に挿入すると、屈曲部近傍が起点となって第１及び第２板状部の挿入方向基端側が挿入孔の周縁部に向けて付勢されることになる。この起点となる屈曲部に対応する部位に第１突出部を設けて第１及び第２板状部の屈曲部に対応する部位を互いに離すようにしているので、第１及び第２板状部をヘッダタンクの挿入孔の周縁部に一層強く圧接させることが可能になる。 According to this configuration, when the first and second plate-like portions are overlapped with each other and inserted into the insertion hole, the vicinity of the bent portion starts from the insertion direction proximal end side of the first and second plate-like portions. It is biased toward the peripheral edge. Since the first projecting portion is provided at a portion corresponding to the bent portion serving as the starting point and the portions corresponding to the bent portions of the first and second plate-like portions are separated from each other, the first and second plate-like portions are provided. Can be more strongly pressed against the peripheral edge of the insertion hole of the header tank.

請求項３の発明では、請求項１または２の発明において、第１突出部は、第１板状部の平面視で挿入方向と直交する方向の中間部に位置付けられ、第２板状部には、上記第１板状部へ向けて突出する第２突出部が、上記第１突出部の挿入方向と直交する方向の両側にそれぞれ位置するように設けられている構成とする。 According to a third aspect of the invention, in the first or second aspect of the invention, the first projecting portion is positioned at an intermediate portion in a direction orthogonal to the insertion direction in a plan view of the first plate-like portion, and is formed on the second plate-like portion.

The slit 5b is formed. The slit 5 b is formed so as to extend in the circumferential direction of the peripheral wall portion of the header tank 5. Similarly, a slit (not shown) for inserting the partition member 17 into the hollow portion R of the header tank 6 is formed in the peripheral wall portion of the right header tank 6. The slits 5b of the left header tank 5 and the right header tank 6 have the same shape.

上記仕切部材１５、１６、１７は共通化されている。以下、仕切部材１５の構造について詳しく説明する。この仕切部材１５は、図３〜図７に示すように、両面がろう材により被覆されたアルミニウム合金製の板材から成形されたものであり、図８に示すように、上記ヘッダタンク５の中空部Ｒ内で略水平に延びる第１板状部１５ａとこの第１板状部１５ａの上側に重なる第２板状部１５ｂとを備えている。これら第１及び第２板状部１５ａ、１５ｂは、その周縁部のうち、挿入方向先端部の一部が連結部１５ｃにより連結されている。 The partition members 15, 16, and 17 are shared. Hereinafter, the structure of the partition member 15 will be described in detail. As shown in FIGS. 3 to 7, the partition member 15 is formed from a plate made of an aluminum alloy whose both surfaces are coated with a brazing material. As shown in FIG. A first plate-like portion 15a extending substantially horizontally in the portion R and a second plate-like portion 15b overlapping above the first plate-like portion 15a are provided. Of these peripheral portions, the first and second plate-like portions 15a and 15b are partially connected at the distal end portion in the insertion direction by a connecting portion 15c.

上記第２板状部１５ｂの周縁部は、ヘッダタンク５の内面に沿うように形成される一方、上記第１板状部１５ａの周縁部は、図３及び図４に示すように、連結部１５ｃの形成部分が上記第２板状部１５ｂの周縁部の対応する部分と一致する一方、連結部１５ｃの両側は第２板状部１５ｂの周縁部の内側に位置するように形成されている。図８に示すように、両板状部１５ａ、１５ｂの連結部１５ｃと反対側は、仕切部材１５をスリット５ｂから中空部Ｒに挿入し配置した状態で、上記ヘッダタンク５から突出して外方に位置するように形成されている。第１板状部１５ａのヘッダタンク５の外方に位置する部分には、該ヘッダタンク５の外面に沿って上方へ延びて該外面にろう付けされる接合部１５ｄが形成されており、また、第２板状部１５ｂのヘッダタンク５の外方に位置する部分には、該ヘッダタンク５の外面に沿って下方へ延びる同様な接合部１５ｅが形成されている。 The peripheral portion of the second plate-like portion 15b is formed along the inner surface of the header tank 5, while the peripheral portion of the first plate-like portion 15a is a connecting portion as shown in FIGS. While the formation part of 15c corresponds with the corresponding part of the peripheral part of the said 2nd plate-shaped part 15b, both sides of the connection part 15c are formed so that it may be located inside the peripheral part of the 2nd plate-like part 15b. . As shown in FIG. 8, the side opposite to the connecting portion 15c of both plate-like portions 15a and 15b protrudes outward from the header tank 5 with the partition member 15 inserted and disposed in the hollow portion R from the slit 5b. It is formed so that it may be located in. A portion 15d of the first plate-like portion 15a located outside the header tank 5 is formed with a joint portion 15d extending upward along the outer surface of the header tank 5 and brazed to the outer surface. A similar joint 15e extending downward along the outer surface of the header tank 5 is formed at a portion of the second plate-like portion 15b located outside the header tank 5.

図３及び図６に示すように、第１板状部１５ａの挿入方向基端部と先端部との間には、挿入方向基端側の約半分の領域を第２板状部１５ｂから離れる方向に傾斜させる第１屈曲部１５ｆが設けられている。この第１屈曲部１５ｆは、図３に示すように、平面視で挿入方向と直交して直線状に延びている。第１板状部１５ａには、挿入方向と直交する方向の略中央部に第２板状部１５ｂ側へ突出する第１突出部１５ｇが設けられている。この第１突出部１５ｇは、第１屈曲部１５ｆに対応するように、該第１屈曲部１５ｆ上に位置付けられている。上記第１突出部１５ｇは、平面視で略円形状をなしている。 As shown in FIGS. 3 and 6, an approximately half region on the proximal side in the insertion direction is separated from the second plate 15b between the proximal end and the distal end in the insertion direction of the first plate 15a. A first bent portion 15f that is inclined in the direction is provided. As shown in FIG. 3, the first bent portion 15 f extends linearly perpendicular to the insertion direction in plan view. The first plate-like portion 15a is provided with a first protruding portion 15g that protrudes toward the second plate-like portion 15b at a substantially central portion in a direction orthogonal to the insertion direction. The first protrusion 15g is positioned on the first bent portion 15f so as to correspond to the first bent portion 15f. The first protrusion 15g has a substantially circular shape in plan view.

また、図４及び図６に示すように、第２板状部１５ｂの挿入方向基端部と先端部との間にも、第１板状部１５ａと同様に、挿入方向基端側の約半分の領域を第１板状部１５ａから離れるように傾斜させる第２屈曲部１５ｈが設けられている。この第２屈曲部１５ｈは、平面視で上記第１屈曲部１５ｆと重複するように位置している。 Further, as shown in FIGS. 4 and 6, between the proximal end portion and the distal end portion in the insertion direction of the second plate-like portion 15b, as in the case of the first plate-like portion 15a, about the insertion direction proximal end side. A second bent portion 15h is provided to incline the half area away from the first plate-like portion 15a. The second bent portion 15h is positioned so as to overlap the first bent portion 15f in plan view.

上記第２板状部１５ｂには、第１板状部１５ａへ向けて突出する２つの第２突出部１５ｊが設けられている。これら第２突出部１５ｊは、第２屈曲部１５ｈに対応するように、平面視で、第１突出部１５ｇの挿入方向と直交する方向の両側にそれぞれ位置付けられている。この第２突出部１５ｊの突出高さと第１突出部１５ｇの突出高さとは、略同じに設定されている。従って、両板状部１５ａ、１５ｂを折りたたんだ状態では、第１突出部１５ｇの先端面は第２板状部１５ｂに、第２突出部１５ｊの先端面は第１板状部１５ａにそれぞれ同じように当たることになる。また、上記第１板状部１５ａの厚さと、第２板状部１５ｂの厚さと、第１突出部１５ｇの高さとを加えた寸法は、上記ヘッダタンク５のスリット５ｂの幅寸法以上に設定されている。 The second plate-like portion 15b is provided with two second protruding portions 15j that protrude toward the first plate-like portion 15a. These second protrusions 15j are positioned on both sides in a direction orthogonal to the insertion direction of the first protrusion 15g in plan view so as to correspond to the second bent part 15h. The protrusion height of the second protrusion 15j and the protrusion height of the first protrusion 15g are set to be substantially the same. Therefore, in a state where both plate-like portions 15a and 15b are folded, the tip surface of the first projecting portion 15g is the same as the second plate-like portion 15b, and the tip surface of the second projecting portion 15j is the same as the first plate-like portion 15a. Will be hit. Further, the dimension obtained by adding the thickness of the first plate-like part 15a, the thickness of the second plate-like part 15b, and the height of the first projecting part 15g is set to be equal to or larger than the width dimension of the slit 5b of the header tank 5. Has been.

上記連結部１５ｃを折り曲げて第１及び第２板状部１５ａ、１５ｂを互いに重ね合わせると、突出部１５ｇ、１５ｊにより、第１及び第２板状部１５ａ、１５ｂが厚み方向に離れた状態になる。このとき、図６に示すように、第１板状部１５ａの第１屈曲部１５ｆよりも挿入方向基端側と第２板状部１５ｂの第２屈曲部１５ｈよりも挿入方向基端側との離間寸法は、これら屈曲部１５ｆ、１５ｈが形成されていることによって、基端部に近づくほど大きくなる。この仕切部材１５の挿入方向基端側の厚さ方向の寸法は、スリット５ｂの幅寸法よりも長くなっている。また、図３及び図４に示すように、第１及び第２板状部１５ａ、１５ｂを設計通りに折り曲げると、平面視で、第１板状部１５ａの周縁部における連結部１５ｃ両側が、それぞれ第２板状部１５ｂの周縁部よりも同じ寸法だけ内側に位置するようになっている。 When the connecting portion 15c is bent and the first and second plate-like portions 15a and 15b are overlapped with each other, the first and second plate-like portions 15a and 15b are separated in the thickness direction by the protruding portions 15g and 15j. Become. At this time, as shown in FIG. 6, the insertion direction base end side of the first plate-like portion 15a from the first bending portion 15f and the insertion direction base end side of the second plate-like portion 15b from the second bending portion 15h. Since the bent portions 15f and 15h are formed, the separation distance of increases as the distance from the proximal end portion increases. The dimension in the thickness direction on the proximal end side in the insertion direction of the partition member 15 is longer than the width dimension of the slit 5b. Further, as shown in FIGS. 3 and 4, when the first and second plate-like portions 15a and 15b are bent as designed, both sides of the connecting portion 15c in the peripheral portion of the first plate-like portion 15a are seen in plan view. Each of the second plate-like portions 15b is located on the inner side by the same dimension as the peripheral portion.

次に、上記のように構成された凝縮器１を製造する要領について説明する。まず、上記仕切部材１５を得る際には、始めに、図示しないが、上記板材をプレス成形することにより、第１及び第２板状部１５ａ、１５ｂを展開した平板状の中間成形品を得る。そして、この仕切部材１５の中間成形品は、図５に示すように、連結部１５ｃを曲げて第１板状部１５ａと第２板状部１５ｂとが略直交する形状とされた後、凝縮器１の製造現場に搬送される。 Next, the point which manufactures the condenser 1 comprised as mentioned above is demonstrated. First, when the partition member 15 is obtained, first, although not shown, a plate-like intermediate molded product in which the first and second plate-like portions 15a and 15b are developed is obtained by press-molding the plate material. . Then, as shown in FIG. 5, the intermediate molded product of the partition member 15 is condensed after the connecting portion 15c is bent so that the first plate-like portion 15a and the second plate-like portion 15b are substantially orthogonal to each other. It is transported to the manufacturing site of the device 1.

凝縮器１の製造現場では、図６に示すように、第１及び第２板状部１５ａ、１５ｂが互いに重なり合うように連結部１５ｃを折り曲げる。このとき、第１板状部１５ａの周縁部を第２板状部１５ｂの周縁部の内側に位置するように形成しているので、第１板状部１５ａ及び第２板状部１５ｂが設計通りに折り曲げられずに多少ずれていても、そのずれ量が両板状部１５ａ、１５ｂの周縁部の寸法差内である場合には、第１板状部１５ａの周縁部が第２板状部１５ｂの周縁部の外側に位置するようになることはない。 At the manufacturing site of the condenser 1, as shown in FIG. 6, the connecting portion 15c is bent so that the first and second plate-like portions 15a and 15b overlap each other. At this time, the first plate-like portion 15a and the second plate-like portion 15b are designed because the peripheral portion of the first plate-like portion 15a is located inside the peripheral portion of the second plate-like portion 15b. Even if it is slightly bent without being bent, if the amount of shift is within the dimensional difference between the peripheral portions of both plate-like portions 15a and 15b, the peripheral portion of the first plate-like portion 15a is the second plate-like shape. It does not come to be located outside the peripheral edge of the portion 15b.

上記第１及び第２板状部１５ａ、１５ｂを互いに重ね合わせた状態で、仕切部材１５を連結部１５ｃ側からスリット５ｂに挿入していく。このとき、上記のように第２板状部１５ｂの周縁部が第１板状部１５ａの周縁部の外側に位置していないので、仕切部材１５をスリット５ｂに挿入する際の挿入力が増大しない。 The partition member 15 is inserted into the slit 5b from the connecting portion 15c side while the first and second plate-like portions 15a and 15b are overlapped with each other. At this time, since the peripheral edge portion of the second plate-like portion 15b is not positioned outside the peripheral edge portion of the first plate-like portion 15a as described above, the insertion force when the partition member 15 is inserted into the slit 5b is increased. do not do.

図８に示すように、仕切部材１５を中空部Ｒに完全に挿入すると、第１突出部１５ｇを第２板状部１５ｂに当てるとともに、第２突出部１５ｊを第１板状部１５ａに当てて両板状部１５ａ、１５ｂを厚み方向に離しているので、従来例の仕切部材のように屈曲部の形状が復元することによる板状部の付勢力の低下が起こらない。このため、両板状部１５ａ、１５ｂをスリット５ｂの周縁部に向けて十分な力で付勢することが可能になる。これにより、第１及び第２板状部１５ａ、１５ｂをスリット５ｂの周縁部に圧接させることが可能になる。 As shown in FIG. 8, when the partition member 15 is completely inserted into the hollow portion R, the first projecting portion 15g is applied to the second plate-shaped portion 15b, and the second projecting portion 15j is applied to the first plate-shaped portion 15a. Since the two plate-like portions 15a and 15b are separated from each other in the thickness direction, the urging force of the plate-like portion is not reduced due to the shape of the bent portion being restored as in the conventional partition member. For this reason, both plate-like parts 15a and 15b can be urged | biased with sufficient force toward the peripheral part of the slit 5b. Thereby, it becomes possible to press-contact the 1st and 2nd plate-shaped parts 15a and 15b to the peripheral part of the slit 5b.

また、第１及び第２屈曲部１５ｆ、１５ｈを形成しているので、仕切部材１５をスリット５ｂに挿入した状態では、屈曲部１５ｆ、１５ｈ近傍が起点となって両板状部１５ａ、１５ｂの基端側がスリット５ｂの周縁部に向けて付勢されることになる。そして、この起点となる第１及び第２屈曲部１５ｆ、１５ｈに対応する部位に第１突出部１５ｇ及び第２突出部１５ｊを設けて厚み方向に離すようにしているので、第１及び第２板状部１５ａ、１５ｂをスリット５ｂの周縁部に一層強く圧接させることが可能である。 In addition, since the first and second bent portions 15f and 15h are formed, in the state where the partition member 15 is inserted into the slit 5b, the vicinity of the bent portions 15f and 15h starts from the two plate-like portions 15a and 15b. The proximal end side is biased toward the peripheral edge of the slit 5b. Since the first projecting portion 15g and the second projecting portion 15j are provided at portions corresponding to the first and second bent portions 15f and 15h serving as the starting points and separated in the thickness direction, the first and second It is possible to press the plate-like portions 15a and 15b more strongly against the peripheral portion of the slit 5b.

また、第１板状部１５ａの厚さと、第２板状部１５ｂの厚さと、第１突出部１５ｇの高さとを加えた寸法が、スリット５ｂの幅寸法以上に設定されているので、仕切部材１５をスリット５ｂに挿入する際には圧入することになる。これにより、仕切部材１５がスリット５ｂからより一層抜けにくくなる。 Moreover, since the dimension which added the thickness of the 1st plate-shaped part 15a, the thickness of the 2nd plate-shaped part 15b, and the height of the 1st protrusion part 15g is set more than the width dimension of the slit 5b, partition When the member 15 is inserted into the slit 5b, it is press-fitted. Thereby, it becomes much more difficult for the partition member 15 to come out of the slit 5b.

上記のようにして仕切部材１５、１６、１７が組み付けられたヘッダタンク５、６と、チューブ２及びフィン３とを仮組み付けしてから治具によりクランプした後、図示しないが、ろう付け用の炉内に搬入して各部を同時に加熱しろう付けし、その後、炉内から出して冷却する。これにより、仕切部材１５、１６、１７がヘッダタンク５、６に完全に固定された状態になる。 After the header tanks 5 and 6 with the partition members 15, 16 and 17 assembled as described above, the tubes 2 and the fins 3 are temporarily assembled and then clamped with a jig, they are not shown, but for brazing It is carried into the furnace and the parts are heated and brazed at the same time, and then removed from the furnace and cooled. As a result, the partition members 15, 16 and 17 are completely fixed to the header tanks 5 and 6.

したがって、この実施形態に係る凝縮器１によれば、第１板状部１５ａに第２板状部１５ｂ側へ突出する第１突出部１５ｇを設け、第２板状部１５ｂに第１板状部１５ａ側へ突出する第２突出部１５ｊを設けたので、仕切部材１５をヘッダタンク５のスリット５ｂに挿入した際、第１及び第２板状部１５ａ、１５ｂをスリット５ｂの周縁部に向けて付勢する付勢力を十分に確保して該スリット５ｂの周縁部に圧接させることができる。これにより、仕切部材１５をヘッダタンク５に組み付けた状態で搬送する際に、仕切部材１５をヘッダタンク５に完全に固定するまで正規の組み付け位置に保持しておくことができ、ヘッダタンク５の仕切部分が連通してしまうのを抑制することができる。左側ヘッダタンク６についても同様である。 Therefore, according to the condenser 1 according to this embodiment, the first plate-like portion 15a is provided with the first protruding portion 15g that protrudes toward the second plate-like portion 15b, and the second plate-like portion 15b is provided with the first plate-like shape. Since the second projecting portion 15j projecting toward the portion 15a is provided, when the partition member 15 is inserted into the slit 5b of the header tank 5, the first and second plate-like portions 15a and 15b are directed toward the peripheral edge of the slit 5b. A sufficient urging force to be urged can be secured and brought into press contact with the peripheral edge of the slit 5b. As a result, when the partition member 15 is transported in a state where it is assembled to the header tank 5, the partition member 15 can be held in the proper assembly position until it is completely fixed to the header tank 5. It can suppress that a partition part communicates. The same applies to the left header tank 6.

また、第１屈曲部１５ｆに対応するように第１突出部１５ｇを設けるとともに、第２屈曲部１５ｈに対応するように第２突出部１５ｊを設け、両板状部１５ａ、１５ｂをスリット５ｂの周縁部に一層強く圧接するようにしたので、仕切部材１５が正規の組み付け位置からずれるのを未然に防止することができる。 In addition, the first protruding portion 15g is provided so as to correspond to the first bent portion 15f, the second protruding portion 15j is provided so as to correspond to the second bent portion 15h, and both the plate-like portions 15a, 15b are connected to the slit 5b. Since the peripheral edge portion is pressed more strongly, it is possible to prevent the partition member 15 from deviating from the normal assembly position.

また、第１及び第２板状部１５ａ、１５ｂが多少ずれて折り曲げられた場合に、第１板状部１５ａの周縁部が第２板状部１５ｂの周縁部の外側に位置しないようになっているので、仕切部材１５の挿入力の増大を回避でき、仕切部材１５の組み付け作業性を良好にできる。 Further, when the first and second plate-like portions 15a and 15b are bent with a slight shift, the peripheral edge portion of the first plate-like portion 15a is not positioned outside the peripheral edge portion of the second plate-like portion 15b. Therefore, an increase in the insertion force of the partition member 15 can be avoided, and the assembly workability of the partition member 15 can be improved.

また、第１板状部１５ａの厚さと第２板状部１５ｂの厚さと第１突出部１５ｇの高さとを加えた寸法を、スリット５ｂの幅寸法よりも長く設定したので、仕切部材１５が正規の組み付け位置からずれるのを未然に防止することができる。 Moreover, since the dimension which added the thickness of the 1st plate-shaped part 15a, the thickness of the 2nd plate-shaped part 15b, and the height of the 1st protrusion part 15g was set longer than the width dimension of the slit 5b, the partition member 15 is set. It is possible to prevent deviation from the normal assembly position.

また、第１及び第２突出部１５ｇ、１５ｊは、平面視で、挿入方向と直交する方向に交互に並ぶことになる。これにより、第１及び第２板状部１５ａ、１５ｂの広い範囲ががたつかないように安定した状態で互いに離れるようになり、その結果、第１及び第２板状部１５ａ、１５ｂを安定してスリット５ｂの周縁部に圧接できる。 The first and second projecting portions 15g and 15j are alternately arranged in a direction orthogonal to the insertion direction in plan view. As a result, the first and second plate-like portions 15a and 15b are separated from each other in a stable state so that the wide range of the first and second plate-like portions 15a and 15b does not rattle. As a result, the first and second plate-like portions 15a and 15b are stabilized. Thus, it can be pressed against the peripheral edge of the slit 5b.

尚、この実施形態では、第１突出部１５ｇの形状を平面視で円形状としているが、例えば、挿入方向と略直交する方向に長く延びる形状としてもよい。このように第１突出部１５ｇを長く延びる形状とする場合に、図９及び図１０に示す変形例１のように、平面視で略矩形状としてもよいし、図１１に示す変形例２のように、平面視で長円形状としてもよい。この第１突出部１５ｇも、第１屈曲部１５ｆに対応するように設けられている。これら変形例のように第１突出部１５ｇを長く延びる形状とすることで、両板状部１５ａ、１５ｂの広い範囲をがたつなないように安定した状態で離すことができる。これら変形例の場合には、第２突出部が省略されているが、第２突出部を設けることも可能である。 In addition, in this embodiment, although the shape of the 1st protrusion part 15g is circular shape by planar view, it is good also as a shape extended long in the direction substantially orthogonal to an insertion direction, for example. Thus, when making the 1st protrusion part 15g into the shape extended long, it is good also as a substantially rectangular shape by planar view like the modification 1 shown in FIG.9 and FIG.10, or the modification 2 shown in FIG. Thus, it is good also as an ellipse shape by planar view. The first protrusion 15g is also provided so as to correspond to the first bent portion 15f. By making the 1st protrusion part 15g into the shape extended long like these modifications, it can be released | separated in the stable state so that the wide range of both plate-shaped parts 15a and 15b may not be connected. In the case of these modified examples, the second protrusion is omitted, but it is also possible to provide the second protrusion.

また、例えば、図１２及び図１３に示す変形例３のように、第１板状部１５ａに、ヘッダタンク５のスリット５ｂの周縁部に中空部Ｒ側から係合する係合突起１５ｉを設けてもよい。この変形例によれば、仕切部材１５をヘッダタンク５の中空部Ｒに挿入すると、仕切部材１５の係合突起１５ｉがスリット５ｂの周縁部に中空部Ｒ側から係合するので、仕切部材１５をヘッダタンク５に確実に保持することができる。 Further, for example, as in Modification 3 shown in FIGS. 12 and 13, the first plate-like portion 15 a is provided with an engagement protrusion 15 i that engages from the hollow portion R side at the peripheral edge of the slit 5 b of the header tank 5. May be.
