Description

タンク取り付け構造及びタンク取り付け方法Tank mounting structure and tank mounting method
　本発明は、タンクがプレートに取り付けられるタンク取り付け構造、及びタンク取り付け方法に関する。 The present invention relates to a tank mounting structure in which a tank is mounted on a plate, and a tank mounting method.
　ＪＰ５８－１６５４８９Ｕには、熱交換器の流路を形成するタンクと、タンクの開口端が固定されるヘッダープレートと、を備えるタンク取り付け構造が開示されている。 JP58-165489U discloses a tank mounting structure including a tank that forms a flow path of a heat exchanger, and a header plate to which an open end of the tank is fixed.
　上記タンクには、複数の端部爪部が一列に並んで突出している。ヘッダープレートは、タンクの開口端に沿うように延在する周縁部と、周縁部に開口して端部爪部に係合する係止窓と、を有する。 The tank has a plurality of end claw portions protruding in a line. The header plate includes a peripheral edge extending along the opening end of the tank, and a locking window that opens to the peripheral edge and engages with the end claw.
　上記熱交換器の製造時には、ヘッダープレートにタンクが組み付けられた状態で、周縁部を折り曲げて、係止窓を端部爪部に係合させる。これにより、端部爪部が係止窓に当接して加締められることで、タンクがヘッダープレートに固定される。 At the time of manufacturing the heat exchanger, with the tank assembled to the header plate, the peripheral edge portion is bent and the locking window is engaged with the end claw portion. Thus, the tank is fixed to the header plate by the end claw portion being brought into contact with the locking window and being crimped.
　しかしながら、ＪＰ５８－１６５４８９Ｕに記載されたタンク取り付け構造では、ヘッダープレートの強度を充分に確保しようとすると、ヘッダープレートを大きく形成する必要があるため、熱交換器の大型化を招く。 However, in the tank mounting structure described in JP58-165489U, it is necessary to make the header plate large if an attempt is made to sufficiently ensure the strength of the header plate, resulting in an increase in the size of the heat exchanger.
　本発明は、タンク取り付け構造の小型化を図ることを目的とする。 The present invention aims to reduce the size of the tank mounting structure.
　本発明のある態様によれば、プレートにタンクの開口端部を取り付けるタンク取り付け構造であって、前記タンクは、前記開口端部から突出する突起を有し、前記プレートは、前記開口端部に沿って延在する延在部と、前記延在部に開口して前記突起に係合する穴と、を有し、前記穴の内周は、前記突起に当接して前記タンクを前記プレートに固定する固定辺と、前記固定辺から曲折して前記固定辺に対して鋭角に傾斜する側方辺と、を有する、タンク取り付け構造が提供される。 According to an aspect of the present invention, there is provided a tank mounting structure for attaching an opening end of a tank to a plate, the tank having a protrusion protruding from the opening end, and the plate at the opening end. An extending portion extending along the hole, and a hole that opens into the extending portion and engages with the protrusion, and an inner periphery of the hole abuts the protrusion so that the tank is attached to the plate. There is provided a tank mounting structure having a fixed side to be fixed and a side side bent from the fixed side and inclined at an acute angle with respect to the fixed side.
　上記態様によれば、延在部では、固定辺が突起から受ける反力によって生じる応力が側方辺のまわりに分散する。こうしてタンク取り付け構造は、延在部に応力が集中することを抑えて、プレートの板厚を小さくすることで、タンク取り付け構造の小型化が図れる。 According to the above aspect, in the extending portion, the stress generated by the reaction force received by the fixed side from the protrusion is dispersed around the side side. In this way, the tank mounting structure can reduce the size of the tank mounting structure by suppressing the concentration of stress on the extending portion and reducing the plate thickness.

　以下、添付図面を参照しながら、本発明の実施形態について説明する。 Hereinafter, embodiments of the present invention will be described with reference to the accompanying drawings.
　図１は、本実施形態に係るタンク取り付け構造を有する熱交換器１を示す。なお、説明の簡略化のため、熱交換器１は一部を省略して図示している。 FIG. 1 shows a heat exchanger 1 having a tank mounting structure according to this embodiment. For simplification of description, the heat exchanger 1 is shown with a part thereof omitted.
　熱交換器１は、エンジン（図示省略）に過給される吸気（流体）を冷却液（媒体）によって冷却する水冷式チャージエアクーラとして用いられる。 The heat exchanger 1 is used as a water-cooled charge air cooler that cools intake air (fluid) supercharged to an engine (not shown) with a coolant (medium).
　熱交換器１は、吸気を導く一対のタンク１０（流路部材）と、冷却液が循環する熱交換部としてのコア３０と、を備える。コア３０は、一対のタンク１０の間に介装される。タンク１０を通じてコア２を流通する吸気は、コア２の内部を流通する冷却液に放熱して冷却される。 The heat exchanger 1 includes a pair of tanks 10 (flow path members) that guide intake air, and a core 30 as a heat exchange unit through which the coolant circulates. The core 30 is interposed between the pair of tanks 10. The intake air flowing through the core 2 through the tank 10 is cooled by releasing heat to the coolant flowing through the core 2.
　金属製のコア３０は、積層される複数のチューブ（図示省略）と、チューブを収容する箱状に形成される複数のコアプレート３１（流路部材）と、コアプレート３１に接続する一対のパイプ３３と、を有する。エンジンの運転時に、ポンプ（図示省略）から配管を通じて送られる冷却液は、黒矢印で示すように、一方のパイプ３３を通じてチューブの内部に流入し、チューブの内部を流通した後に他方のパイプ３３から流出する。 The metal core 30 includes a plurality of tubes (not shown) to be stacked, a plurality of core plates 31 (flow path members) formed in a box shape that accommodates the tubes, and a pair of pipes connected to the core plate 31 33. During operation of the engine, the coolant sent from the pump (not shown) through the pipe flows into the tube through one pipe 33 as shown by the black arrow, and after flowing through the inside of the tube, from the other pipe 33 leak.
　樹脂製のタンク１０は、コア３０に向けて開口するドーム状の開口端部１１と、コア３０と反対側に向けて開口する円筒状の筒部１３と、を有する。筒部１３にはダクト（図示省略）が接続される。吸気は、白抜き矢印で示すように一方のタンク１０を通じてコアプレート３１の内部に流入し、チューブのまわりを流通した後、他方のタンク１０から流出する。 The resin tank 10 includes a dome-shaped opening end portion 11 that opens toward the core 30 and a cylindrical tube portion 13 that opens toward the opposite side of the core 30. A duct (not shown) is connected to the cylindrical portion 13. The intake air flows into the core plate 31 through one tank 10 as indicated by the white arrow, flows around the tube, and then flows out from the other tank 10.
　図２は、タンク取り付け構造を示す正面図である。コアプレート３１の開口端部には枠状のプレート４０が接合される。タンク１０の開口端部１１は、プレート４０を介してコア３０に取り付けられる。 FIG. 2 is a front view showing a tank mounting structure. A frame-shaped plate 40 is joined to the open end of the core plate 31. The open end 11 of the tank 10 is attached to the core 30 via the plate 40.
　開口端部１１は、略矩形の断面形状を有する筒状に形成される。開口端部１１は、一対の短辺部１１Ａと、各短辺部１１Ａにわたって延在する一対の長辺部１１Ｂと、を有する。これにより、開口端部１１は、略矩形の断面を有する流路を形成する。 The opening end portion 11 is formed in a cylindrical shape having a substantially rectangular cross-sectional shape. Open end 11 has a pair of short sides 11A and a pair of long sides 11B extending over each short side 11A. Thereby, the opening end part 11 forms the flow path which has a substantially rectangular cross section.
　プレート４０とコア３０との間には、開口端部１１を収容する収容溝としての溝３２が形成される。溝３２は、コア３０のまわりに延在する略矩形の環状に形成される。溝３２とタンク１０の開口端部１１との間には、シール部材（図示省略）が介装される。シール部材は、ゴム材などの弾性材によって形成される。 Between the plate 40 and the core 30, a groove 32 is formed as an accommodation groove for accommodating the open end 11. The groove 32 is formed in a substantially rectangular annular shape extending around the core 30. A seal member (not shown) is interposed between the groove 32 and the open end 11 of the tank 10. The seal member is formed of an elastic material such as a rubber material.
　プレート４０は、Ｌ字形の断面形状を有する。なお、プレート４０は、これに限らず、Ｓ字形の断面形状を有ものであってもよい。この場合、溝３２は、コア３０を介さず、プレートのみによって形成される。 The plate 40 has an L-shaped cross-sectional shape. The plate 40 is not limited to this, and may have an S-shaped cross-sectional shape. In this case, the groove 32 is formed only by the plate without the core 30.
　プレート４０は、開口端部１１のまわりに沿うように延在する延在部４２を有する。延在部４２には、各突起１５に係合する複数の穴５０が形成される。延在部４２は、開口端部１１に沿って延在する板状に形成され、各穴５０が一列に並んで開口している。なお、これに限らず、延在部４２は、複数の爪状の部位が並ぶように形成され、各爪状の部位に穴５０が個別に開口するものであってもよい。 The plate 40 has an extending portion 42 extending along the periphery of the opening end portion 11. The extending portion 42 is formed with a plurality of holes 50 that engage with the protrusions 15. The extending portion 42 is formed in a plate shape extending along the opening end portion 11, and the holes 50 are opened in a row. In addition, the extension part 42 may be formed so that a plurality of claw-shaped parts are arranged, and the holes 50 may be individually opened in each claw-shaped part.
　次に、図３を参照して、突起１５及び穴５０の形状について説明する。 Next, the shapes of the protrusions 15 and the holes 50 will be described with reference to FIG.
　突起１５は、略矩形状の断面を有する凸部として形成される。突起１５は、前端１６と、後端１７と、一対の側端１８、１９と、先端２０と、４つの角２１～２４と、を有する。４つの角２１～２４は、直角に曲折する。 The protrusion 15 is formed as a convex portion having a substantially rectangular cross section. The protrusion 15 has a front end 16, a rear end 17, a pair of side ends 18 and 19, a front end 20, and four corners 21 to 24. The four corners 21 to 24 bend at right angles.
　前端１６と後端１７とは、互いに平行に延在する平面状に形成される。一対の側端１８、１９は、互いに平行に延在する平面状に形成される。 The front end 16 and the rear end 17 are formed in a planar shape extending in parallel with each other. The pair of side ends 18 and 19 are formed in a planar shape extending in parallel to each other.
　一方、穴５０の内周（内面）は、略台形状に形成される。穴５０の内周は、突起１５に当接する固定辺５１（長辺）と、固定辺５１に対向する対向辺５２（短辺）と、固定辺５１と対向辺５２との間に延在する一対の側方辺５３、５４と、４つの隅５５～５８と、を有する。 On the other hand, the inner periphery (inner surface) of the hole 50 is formed in a substantially trapezoidal shape. The inner periphery of the hole 50 extends between the fixed side 51 (long side) that contacts the protrusion 15, the opposing side 52 (short side) that faces the fixed side 51, and the fixed side 51 and the opposing side 52. A pair of side edges 53 and 54 and four corners 55 to 58 are provided.
　固定辺５１、対向辺５２、及び側方辺５３、５４は、図中二点鎖線で示す台形Ｔに沿って直線状（平面状）に延在する。なお、これに限らず、固定辺５１、対向辺５２、及び側方辺５３、５４は、曲線状に延在するものであってもよい。側方辺５３、５４は、固定辺５１に対して直角より小さい鋭角に傾斜する。 The fixed side 51, the opposite side 52, and the side sides 53 and 54 extend linearly (planar) along a trapezoid T indicated by a two-dot chain line in the drawing. In addition, not only this but the fixed side 51, the opposing side 52, and the side sides 53 and 54 may extend in the shape of a curve. The side sides 53 and 54 are inclined at an acute angle smaller than a right angle with respect to the fixed side 51.
　４つの隅５５～５８は、円弧状に曲折する。なお、これに限らず、隅５５～５８は、図中二点鎖線で示す台形Ｔに沿って直線状に曲折するものであってもよい。 4 corners 55-58 bend in an arc. However, the present invention is not limited to this, and the corners 55 to 58 may be bent linearly along a trapezoid T indicated by a two-dot chain line in the drawing.
　側方辺５３と突起１５の側端１８との間には、テーパ状の空隙６３が形成される。固定辺５１が延在する方向（図３において左右方向）について空隙６３の開口幅Ｌは、固定辺５１から離れるのにしたがって次第に小さくなる。同様に、側方辺５４と突起１５の側端１９との間には、テーパ状の空隙６４が形成される。対向辺５２と突起１５の後端１７との間には、空隙６２が形成される。 A tapered gap 63 is formed between the side edge 53 and the side edge 18 of the protrusion 15. In the direction in which the fixed side 51 extends (left and right direction in FIG. 3), the opening width L of the gap 63 gradually decreases as the distance from the fixed side 51 increases. Similarly, a tapered gap 64 is formed between the side edge 54 and the side end 19 of the protrusion 15. A gap 62 is formed between the opposite side 52 and the rear end 17 of the protrusion 15.
　図４は、熱交換器１の製造時にタンク１０をプレート４０に固定する加締め工程を示す熱交換器１の正面図である。加締め工程では、プレート４０にタンク１０を組み付けた状態で、図中矢印で示すように各延在部４２の基端部を座部４１（図２参照）から折り曲げる。これにより、図１に示すように、各延在部４２がタンク１０の開口端部１１に沿う位置に来ることで、各穴５０の固定辺５１が各突起１５の前端１６に係合して加締められる。こうして、プレート４０にタンク１０が固定される。以上のようにして、熱交換器１は製造される。 FIG. 4 is a front view of the heat exchanger 1 showing a caulking process for fixing the tank 10 to the plate 40 when the heat exchanger 1 is manufactured. In the caulking step, the base end portion of each extending portion 42 is bent from the seat portion 41 (see FIG. 2) as indicated by an arrow in the state where the tank 10 is assembled to the plate 40. Thereby, as shown in FIG. 1, each extending portion 42 comes to a position along the opening end portion 11 of the tank 10, so that the fixed side 51 of each hole 50 is engaged with the front end 16 of each projection 15. It is crimped. Thus, the tank 10 is fixed to the plate 40. The heat exchanger 1 is manufactured as described above.
　次に、熱交換器１の作用について説明する。 Next, the operation of the heat exchanger 1 will be described.
　熱交換器１の作動時において、タンク１０は、シール部材の弾性復元力を開口端部１１の端面に受けると共に、タンク１０の内面に吸気の圧力を受ける。タンク１０は、穴５０に係合した突起１５によってプレート４０から離れないように支持される。このとき、突起１５は、穴５０の固定辺５１に係合した前端１６が延在部４２に引張荷重を与える。延在部４２には、固定辺５１が突起１５の前端１６から受ける反力によって応力が生じる。延在部４２では、側方辺５３、５４が固定辺５１に対して傾斜する角度を拡げるように変形することで、側方辺５３、５４のまわりに応力が分散する。 During the operation of the heat exchanger 1, the tank 10 receives the elastic restoring force of the seal member on the end surface of the opening end 11 and the intake pressure on the inner surface of the tank 10. The tank 10 is supported so as not to be separated from the plate 40 by the protrusion 15 engaged with the hole 50. At this time, in the protrusion 15, the front end 16 engaged with the fixed side 51 of the hole 50 applies a tensile load to the extending portion 42. In the extending portion 42, stress is generated by a reaction force that the fixed side 51 receives from the front end 16 of the protrusion 15. In the extending portion 42, the side sides 53 and 54 are deformed so as to increase the angle at which the side sides 53 and 54 are inclined with respect to the fixed side 51, whereby stress is dispersed around the side sides 53 and 54.
　図５Ａは、比較例として、穴５０の側方辺５３が、固定辺５１に対して傾斜せずに直交するタンク取り付け構造において、延在部４２に生じる応力の分布を示す図である。延在部４２では、側方辺５３のまわりの領域Ｓ１、Ｓ２、Ｓ３、Ｓ４、Ｓ５の順に応力が高まり、隅５７の近傍に位置する領域Ｓ４、Ｓ５に応力が集中する。 FIG. 5A is a diagram showing a distribution of stress generated in the extending portion 42 in a tank mounting structure in which the side side 53 of the hole 50 is orthogonal to the fixed side 51 without being inclined as a comparative example. In the extending portion 42, the stress increases in the order of the regions S1, S2, S3, S4, and S5 around the lateral side 53, and the stress is concentrated in the regions S4 and S5 located in the vicinity of the corner 57.
　図５Ｂは、本発明の延在部４２に生じる応力の分布を示す図である。延在部４２では、側方辺５３のまわりの領域Ｓ１、Ｓ２、Ｓ３の順に応力が高まり、隅５７の近傍に位置する領域Ｓ３に応力が集中することが抑えられる。 FIG. 5B is a diagram showing a distribution of stress generated in the extending portion 42 of the present invention. In the extending portion 42, the stress increases in the order of the regions S 1, S 2, S 3 around the lateral side 53, and the stress is suppressed from concentrating on the region S 3 located in the vicinity of the corner 57.
　次に、本実施形態の効果について説明する。 Next, the effect of this embodiment will be described.
　熱交換器１のタンク取り付け構造は、タンク１０と、タンク１０が取り付けられるプレート４０と、を備える。タンク１０は、プレート４０に固定される開口端部１１と、開口端部１１のまわりから突出する突起１５と、を有する。プレート４０は、開口端部１１のまわりに沿うように延在する延在部４２と、延在部４２に開口して突起１５に係合する穴５０と、を有する。突起１５に穴５０を係合させることでタンク１０がプレート４０に取り付けられる。穴５０の内周は、突起１５に当接してタンク１０をプレート４０に固定する固定辺５１と、固定辺５１から曲折して固定辺５１に鋭角を持って傾斜する側方辺５３、５４と、を有する。 The tank mounting structure of the heat exchanger 1 includes a tank 10 and a plate 40 to which the tank 10 is mounted. The tank 10 includes an open end 11 that is fixed to the plate 40, and a protrusion 15 that protrudes from around the open end 11. The plate 40 includes an extending portion 42 that extends around the opening end portion 11, and a hole 50 that opens to the extending portion 42 and engages with the protrusion 15. The tank 10 is attached to the plate 40 by engaging the hole 50 with the protrusion 15. The inner periphery of the hole 50 is a fixed side 51 that contacts the protrusion 15 to fix the tank 10 to the plate 40, and side sides 53 and 54 that are bent from the fixed side 51 and inclined with an acute angle to the fixed side 51. Have.
　上記構成により、延在部４２では、固定辺５１が突起１５の前端１６から受ける反力によって側方辺５３、５４のまわりに応力が分散する。こうして熱交換器１のタンク取り付け構造は、延在部４２に応力が集中することを抑えて、プレート４０の板厚を小さくすることで小型化が図れる。 With the above configuration, in the extending portion 42, the stress is dispersed around the lateral sides 53 and 54 by the reaction force that the fixed side 51 receives from the front end 16 of the protrusion 15. Thus, the tank mounting structure of the heat exchanger 1 can be reduced in size by suppressing the concentration of stress on the extending portion 42 and reducing the plate thickness of the plate 40.
　また、穴５０の内周は、突起１５の両側に延在する一対の側方辺５３、５４を有する。一対の側方辺５３、５４は、固定辺５１が延在する方向の間隔Ｗが固定辺５１から離れるのにしたがって小さくなる。 Further, the inner periphery of the hole 50 has a pair of side sides 53 and 54 extending on both sides of the protrusion 15. The pair of side sides 53 and 54 become smaller as the interval W in the direction in which the fixed side 51 extends is separated from the fixed side 51.
　上記構成により、固定辺５１が突起１５の前端１６から受ける反力によって一対の側方辺５３、５４の間隔Ｗを拡げるように変形をすることで、延在部４２に生じる応力が広い範囲に分散する。 With the above configuration, the stress generated in the extending portion 42 is widened by deforming the fixed side 51 to increase the interval W between the pair of side sides 53 and 54 by the reaction force received from the front end 16 of the protrusion 15. scatter.
　ここで、図６Ａは、比較例として、略矩形状の穴７０を有するタンク取り付け構造を示す。この場合には、隣り合う穴７０どうしで隅７７と隅７８との間に設けられる間隔Ｌ２が設けられる。間隔Ｌ２が短くなると、隅７７及び隅７８の近傍に応力が集中しやすくなる。 Here, FIG. 6A shows a tank mounting structure having a substantially rectangular hole 70 as a comparative example. In this case, an interval L2 provided between the corner 77 and the corner 78 between the adjacent holes 70 is provided. When the distance L2 is shortened, stress is likely to concentrate in the vicinity of the corner 77 and the corner 78.
　これに対して、本発明のタンク取り付け構造は、穴５０の内周が一対の側方辺５３、５４から曲折して固定辺５１に対向するように延在する対向辺５２を有する略台形状である。 On the other hand, the tank mounting structure of the present invention has a substantially trapezoidal shape having opposing sides 52 that extend so that the inner periphery of the hole 50 is bent from the pair of side sides 53 and 54 and faces the fixed side 51. It is.
　上記構成により、図６Ｂに示すように、略台形状の穴５０では、隣り合う穴５０どうしで隅５７と隅５８との間に設けられる間隔Ｌ１が充分に確保されることにより、延在部４２に生じる応力が広い範囲に分散する。 6B, in the substantially trapezoidal hole 50, the space L1 provided between the corner 57 and the corner 58 is sufficiently secured between the adjacent holes 50, so that the extension portion The stress generated in 42 is dispersed over a wide range.
　また、固定辺５１及び側方辺５３、５４は、突起１５との間に空隙６３、６４を形成する。空隙６３、６４は、固定辺５１が延在する方向の開口幅が固定辺５１から離れるのにしたがって小さくなるテーパ状である。 Also, the fixed side 51 and the side sides 53 and 54 form gaps 63 and 64 between the protrusions 15. The gaps 63 and 64 are tapered so that the opening width in the direction in which the fixed side 51 extends decreases as the distance from the fixed side 51 increases.
　上記構成により、突起１５に対して穴７０の隅５５、５６が離されるため、空隙６３、６４に面する固定辺５１、隅５５、５６、及び側方辺５３、５４の近傍部位が変形することで、応力が広い範囲に分散する。 With the above configuration, since the corners 55 and 56 of the hole 70 are separated from the protrusion 15, the portions near the fixed side 51, the corners 55 and 56, and the side sides 53 and 54 facing the gaps 63 and 64 are deformed. As a result, the stress is dispersed over a wide range.
　また、プレート４０は、延在部４２から曲折して延在する座部４１を有する。座部４１は、熱交換器１のコア３０に接合される。延在部４２及び座部４１は、コア３０との間に開口端部１１を収容する溝３２を形成する。 Further, the plate 40 has a seat portion 41 that is bent from the extending portion 42 and extends. The seat 41 is joined to the core 30 of the heat exchanger 1. The extending portion 42 and the seat portion 41 form a groove 32 that accommodates the open end portion 11 between the extending portion 42 and the seat portion 41.
　上記構成により、プレート４０は、断面Ｌ字形のものとなる。このため、熱交換器１は、コア３０からプレート４０が突出する寸法が抑えられ、小型化が図れる。 With the above configuration, the plate 40 has an L-shaped cross section. For this reason, the heat exchanger 1 can be reduced in size because the size of the plate 40 protruding from the core 30 is suppressed.
　なお、突起１５の先端部には、前端１６と後端１７と側端１８、１９が先端２０にかけて湾曲する曲面状に延在する面取り部（図示省略）が形成される構成としてもよい。これにより、各延在部４２が折り曲げられる加締め工程において、穴５０が突起１５の面取り部に摺接して円滑に係合する。 It should be noted that the front end portion of the protrusion 15 may be formed with a chamfered portion (not shown) extending in a curved shape in which the front end 16, the rear end 17, and the side ends 18 and 19 are curved toward the front end 20. Thereby, in the caulking process in which each extending part 42 is bent, the hole 50 slides in contact with the chamfered part of the protrusion 15 and smoothly engages.
　次に、図７Ａ、図７Ｂ、及び図７Ｃに示す突起１５の変形例について説明する。 Next, a modification of the protrusion 15 shown in FIGS. 7A, 7B, and 7C will be described.

The rear end 17 is formed in a curved shape that curves toward the front end 20. In this case, in the caulking process in which each extending portion 42 is bent, the hole 50 is in sliding contact with the substantially arcuate corners 23 and 24 of the protrusion 15 and the curved portion of the rear end 17 and smoothly engages.
　図７Ｂに示す突起１５は、略台形状の断面を有する凸部として形成される。一対の側端１８、１９は、互いに傾斜して延在する平面状に形成される。この場合に、各延在部４２が折り曲げられる加締め工程において、略台形状の穴５０が突起１５の側端１８、１９に摺接して円滑に係合する。 7B is formed as a convex portion having a substantially trapezoidal cross section.

The inner periphery of the hole 50 has a fixed side 51 that contacts the protrusion 15 and a pair of side sides 53 and 54 that extend in an arc shape from both ends of the fixed side 51. In this case, in the caulking process in which each extending portion 42 is bent, the lateral sides 53 and 54 of the hole 50 are slidably contacted with the substantially arc-shaped outer periphery of the protrusion 15 and smoothly engaged.
　図８Ｂに示す突起１５は、略三角形状の断面を有する凸部として形成される。突起１５は、平面状に形成される前端１６と、略三角形状に傾斜する一対の側端１８、１９と、を有する。穴５０は、図３に示すものと同様に、略台形状の内周を有する。この場合に、各延在部４２が折り曲げられる加締め工程において、穴５０の側方辺５３、５４が突起１５の略三角形状をした側端１８、１９に摺接して円滑に係合する。 The protrusion 15 shown in FIG. 8B is formed as a convex portion having a substantially triangular cross section. The protrusion 15 has a front end 16 formed in a planar shape and a pair of side ends 18 and 19 inclined in a substantially triangular shape.

　枠部４５は、Ｌ字形の断面形状を有し、コア３０のまわりに延在する略矩形の枠状に形成される。枠部４５の内周端は、コアプレート３１に接合される。枠部４５とコアプレート３１（コア３０）との間には、開口端部１１を収容する環状の収容溝としての溝３２が形成される。 The frame portion 45 has an L-shaped cross-sectional shape and is formed in a substantially rectangular frame shape extending around the core 30. The inner peripheral end of the frame portion 45 is joined to the core plate 31. Between the frame part 45 and the core plate 31 (core 30), the groove | channel 32 as an annular | circular accommodation groove | channel which accommodates the opening edge part 11 is formed.
　タンク１０の開口端部１１は、プレート４０の枠部４５に対向して延在する開口端２５と、開口端２５と反対側に並んで延在する凹部２９及び凸部２８と、を有する。 The opening end 11 of the tank 10 has an opening end 25 that extends opposite to the frame portion 45 of the plate 40, and a concave portion 29 and a convex portion 28 that extend side by side on the opposite side of the opening end 25.

　次に、タンク１０をプレート４０に取り付ける方法について説明する。 Next, a method for attaching the tank 10 to the plate 40 will be described.
　図１０から図１２に示すように、熱交換器１の製造時には、タンク１０をプレート４０に取り付ける工程が行われる。この工程では、プレート４０及びタンク１０を挟むように配置される一対の治具１５０が用いられる。 As shown in FIGS. 10 to 12, when manufacturing the heat exchanger 1, a process of attaching the tank 10 to the plate 40 is performed. In this step, a pair of jigs 150 arranged so as to sandwich the plate 40 and the tank 10 are used.
　一対の治具１５０は、ガイドレール（図示省略）によって直線上を移動するように支持され、駆動機構（図示省略）によって駆動される。これにより、一対の治具１５０は、図１０に矢印で示すように、互いに同期しながらプレート４０の枠部４５及びタンク１０の開口端部１１に沿って移動する。 The pair of jigs 150 are supported by a guide rail (not shown) so as to move on a straight line, and are driven by a drive mechanism (not shown). Accordingly, the pair of jigs 150 moves along the frame portion 45 of the plate 40 and the opening end portion 11 of the tank 10 while being synchronized with each other, as indicated by arrows in FIG.
　図１３は、治具１５０を示す斜視図である。治具１５０は、Ｃ字形の断面形状を有するレール状に形成される。治具１５０は、プレート４０の枠部４５を支持する支持部１５１と、タンク１０の凹部２９に係合する係合部１５２と、タンク１０をプレート４０に近づけるスロープ状の押し部１５３と、プレート４０を曲げる曲げ部１５４と、を有する。係合部１５２は、押し部１５３に連接する部位から支持部１５１に向けてフック状に突出する。曲げ部１５４は、支持部１５１及び押し部１５３に連接する部位からプレート４０に向けてテーパ状に突出する。 FIG. 13 is a perspective view showing the jig 150. The jig 150 is formed in a rail shape having a C-shaped cross section. The jig 150 includes a support portion 151 that supports the frame portion 45 of the plate 40, an engagement portion 152 that engages with the concave portion 29 of the tank 10, a slope-like push portion 153 that brings the tank 10 close to the plate 40, and a plate A bending portion 154 that bends 40. The engaging portion 152 protrudes in a hook shape from a portion connected to the push portion 153 toward the support portion 151. The bent portion 154 protrudes in a tapered shape from the portion connected to the support portion 151 and the push portion 153 toward the plate 40.
　治具１５０は、寸法Ｄの範囲で支持部１５１と押し部１５３の間隔が次第に小さくなる圧縮部位１５５と、寸法Ｅの範囲で曲げ部１５４の突出量が次第に大きくなる加締め部位１５６と、を有する。 The jig 150 includes a compression portion 155 in which the distance between the support portion 151 and the pressing portion 153 gradually decreases in the range of the dimension D, and a crimping portion 156 in which the protruding amount of the bending portion 154 gradually increases in the range of the dimension E. Have.
　次に、図１０Ａ、図１０Ｂ、及び図１０Ｃを参照してタンク１０をプレート４０に取り付ける工程を説明する。 Next, a process of attaching the tank 10 to the plate 40 will be described with reference to FIGS. 10A, 10B, and 10C.
　まず、図１０Ａに示すように、プレート４０にタンク１０が組み付けられ、治具１５０の圧縮部位１５５がプレート４０及びタンク１０に嵌合する。これにより、シール部材３６の一端側が規定量まで圧縮される。 First, as shown in FIG. 10A, the tank 10 is assembled to the plate 40, and the compression portion 155 of the jig 150 is fitted to the plate 40 and the tank 10. Thereby, the one end side of the seal member 36 is compressed to a specified amount.
　このときに、図１１に示すように、治具１５０の支持部１５１がプレート４０の枠部４５の背面（下面）を支持し、かつ治具１５０の押し部１５３がタンク１０の凸部２８に当接している。これにより、図１１に実線の矢印で示すように、タンク１０の凸部２８がプレート４０の枠部４５に引き寄せられ、シール部材３６が圧縮される。 At this time, as shown in FIG. 11, the support portion 151 of the jig 150 supports the back surface (lower surface) of the frame portion 45 of the plate 40, and the pressing portion 153 of the jig 150 is placed on the convex portion 28 of the tank 10. It is in contact. As a result, as indicated by solid line arrows in FIG. 11, the convex portion 28 of the tank 10 is attracted to the frame portion 45 of the plate 40, and the seal member 36 is compressed.
　続いて、図１０Ｂに示すように、治具１５０がプレート４０及びタンク１０に嵌合した状態で中程に移動する。これにより、タンク１０の開口端部１１がプレート４０の枠部４５に対して略平行に延在して、シール部材３６が規定量まで圧縮される。 Subsequently, as shown in FIG. 10B, the jig 150 moves in the middle with the plate 40 and the tank 10 being fitted. As a result, the open end 11 of the tank 10 extends substantially parallel to the frame 45 of the plate 40, and the seal member 36 is compressed to a specified amount.
　続いて、図１０Ｃに示すように、治具１５０がプレート４０及びタンク１０に嵌合した状態で移動する。こうして治具１５０が通過することにより、シール部材３６が全域で規定量まで圧縮され、プレート４０の延在部４２が連続的に曲げられる。 Subsequently, as shown in FIG. 10C, the jig 150 moves in a state of being fitted to the plate 40 and the tank 10. By passing the jig 150 in this way, the seal member 36 is compressed to a specified amount in the entire region, and the extending portion 42 of the plate 40 is continuously bent.
　このときに、治具１５０の曲げ部１５４がプレート４０の延在部４２の外面に摺接することで、図１１に破線の矢印で示すように、延在部４２がタンク１０の開口端部１１に沿うように曲げられる。これにより、図１２に示すように、プレート４０の穴５０がタンク１０の突起１５に係合し、タンク１０の開口端部１１がプレート４０に加締め固定される。 At this time, the bending portion 154 of the jig 150 is in sliding contact with the outer surface of the extending portion 42 of the plate 40, so that the extending portion 42 is open at the opening end portion 11 of the tank 10, as indicated by a broken arrow in FIG. 11. It is bent along. Thereby, as shown in FIG. 12, the hole 50 of the plate 40 is engaged with the protrusion 15 of the tank 10, and the open end 11 of the tank 10 is caulked and fixed to the plate 40.
　以上のようにして、タンク１０がプレート４０に取り付けられる。こうして、熱交換器１が製造される。 The tank 10 is attached to the plate 40 as described above. Thus, the heat exchanger 1 is manufactured.
　次に、本実施形態の効果について説明する。 Next, the effect of this embodiment will be described.
　タンク取り付け構造は、タンク１０が取り付けられるプレート４０を備える。プレート４０は、タンク１０の開口端部１１が嵌合する枠部４５と、枠部４５との間に開口端部１１を加締め固定する延在部４２と、を有する。タンク１０の開口端部１１は、プレート４０の枠部４５に対向して延在する開口端２５と、開口端２５と反対側に窪む凹部２９と、を有する。凹部２９が、枠部４５と開口端部１１との位置合わせをする治具１５０に対して枠部４５と共に係合する形状を有する。 The tank mounting structure includes a plate 40 to which the tank 10 is mounted. The plate 40 includes a frame portion 45 in which the opening end portion 11 of the tank 10 is fitted, and an extending portion 42 that crimps and fixes the opening end portion 11 between the frame portion 45. The open end 11 of the tank 10 has an open end 25 that extends to face the frame 45 of the plate 40, and a recess 29 that is recessed on the opposite side of the open end 25. The concave portion 29 has a shape that engages with the frame portion 45 with respect to the jig 150 that aligns the frame portion 45 and the opening end portion 11.
　タンク取り付け方法では、プレート４０の枠部４５及びタンク１０の凹部２９に係合して枠部４５と開口端部１１との位置合わせをする治具１５０を用いてプレート４０の延在部４２による加締め固定が行われる。 In the tank mounting method, the extension portion 42 of the plate 40 uses the jig 150 that engages with the frame portion 45 of the plate 40 and the concave portion 29 of the tank 10 to align the frame portion 45 and the opening end portion 11. The caulking is fixed.
　上記構成により、治具１５０がプレート４０の枠部４５とタンク１０の凹部２９との２箇所に係合することにより、枠部４５と開口端部１１との位置合わせが行われる。これにより、タンク１０の開口端部１１がプレート４０に精度よく組み付けられ、タンク１０の取り付け位置精度を高められる。 With the above configuration, the jig 150 is engaged with the two portions of the frame portion 45 of the plate 40 and the concave portion 29 of the tank 10, whereby the frame portion 45 and the open end portion 11 are aligned. Thereby, the opening end part 11 of the tank 10 is assembled | attached to the plate 40 accurately, and the attachment position precision of the tank 10 can be improved.
　なお、治具１５０は、熱交換器１の製造時に限らず、熱交換器１の整備時に用いてもよい。 Note that the jig 150 may be used not only when the heat exchanger 1 is manufactured but also when the heat exchanger 1 is serviced.
　また、治具１５０は、プレート４０の枠部４５及びタンク１０の開口端部１１に沿って移動する。 Further, the jig 150 moves along the frame portion 45 of the plate 40 and the open end portion 11 of the tank 10.
　上記構成により、治具１５０が移動することによってタンク１０の開口端部１１がプレート４０に取り付けられるため、取り付けにかかる時間が短縮される。 With the above configuration, since the opening end 11 of the tank 10 is attached to the plate 40 by the movement of the jig 150, the time required for attachment is shortened.
　また、治具１５０は、プレート４０の枠部４５に摺接する支持部１５１と、タンク１０の凹部２９に摺接する係合部１５２と、を備える。 Further, the jig 150 includes a support portion 151 that is in sliding contact with the frame portion 45 of the plate 40 and an engagement portion 152 that is in sliding contact with the concave portion 29 of the tank 10.
　上記構成により、治具１５０が移動するときに、延在部４２を曲げる反力が支持部１５１と係合部１５２との２箇所によって支持される。これにより、加締め時に治具１５０に対するプレート４０のズレが抑えられ、延在部４２の曲げ加工が精度よく行われる。 With the above configuration, when the jig 150 moves, the reaction force that bends the extending portion 42 is supported by the two portions of the support portion 151 and the engagement portion 152. Thereby, the shift | offset | difference of the plate 40 with respect to the jig | tool 150 is suppressed at the time of caulking, and the bending process of the extension part 42 is performed accurately.
　また、治具１５０は、タンク１０の開口端部１１（凸部２８）に摺接してタンク１０の開口端２５をプレート４０の枠部４５に近づける押し部１５３をさらに備える。 The jig 150 further includes a pushing portion 153 that slides into contact with the opening end portion 11 (convex portion 28) of the tank 10 and brings the opening end 25 of the tank 10 close to the frame portion 45 of the plate 40.
　上記構成により、治具１５０が移動することで、押し部１５３に押される開口端部１１が枠部４５に対する所定位置に収まる。これにより、シール部材３６が規定量に圧縮された状態で、タンク１０の開口端部１１がプレート４０に取り付けられるため、タンク１０の密封性が確保される。 With the above configuration, when the jig 150 is moved, the opening end portion 11 pushed by the pushing portion 153 fits in a predetermined position with respect to the frame portion 45. Thereby, since the open end 11 of the tank 10 is attached to the plate 40 in a state where the seal member 36 is compressed to a specified amount, the sealing performance of the tank 10 is ensured.
　また、治具１５０は、プレート４０の延在部４２に摺接して延在部４２を曲げる曲げ部１５４をさらに備える。 The jig 150 further includes a bending portion 154 that slidably contacts the extending portion 42 of the plate 40 and bends the extending portion 42.
　上記構成により、治具１５０が移動することで、曲げ部１５４に押される延在部４２の曲げ加工が行われる。このため、延在部４２による開口端部１１の加締め固定が確実に行われる。また、治具１５０が移動するときに、曲げ部１５４が延在部４２を連続的に曲げることにより、加締め固定にかかる時間が短縮される。 With the above configuration, when the jig 150 moves, the extending portion 42 pushed by the bending portion 154 is bent. For this reason, the caulking fixation of the opening end part 11 by the extension part 42 is performed reliably. Further, when the jig 150 moves, the bending portion 154 continuously bends the extending portion 42, whereby the time required for the caulking and fixing is shortened.
　なお、上記した構成に限らず、延在部４２を曲げる機構（図示省略）を治具１５０とは別に設けてもよい。 Note that, not limited to the above-described configuration, a mechanism (not shown) for bending the extending portion 42 may be provided separately from the jig 150.
　ところで、従来の熱交換器の取り付け工程では、治具の上にコアから突出したプレートを載せて支持するようになっていた。このため、治具に対するプレートのズレを抑えるには、コアから突出するプレートの寸法（突出幅）をある程度確保する必要があった。 By the way, in the conventional heat exchanger mounting process, a plate protruding from the core is placed on and supported by a jig. For this reason, in order to suppress the displacement of the plate with respect to the jig, it is necessary to secure a certain dimension (protrusion width) of the plate protruding from the core.
　これに対し、本実施形態では、治具１５０がプレート４０及びタンク１０を挟んで支持するため、コア３０から突出するプレート４０の寸法（突出幅）を従来のものより小さくしても、治具１５０に対するプレート４０のズレを充分に抑えられる。よって、熱交換器１は、プレート４０及びタンク１０の開口端部１１の小型化が図れる。 On the other hand, in the present embodiment, since the jig 150 supports the plate 40 and the tank 10 between them, even if the dimension (projection width) of the plate 40 protruding from the core 30 is smaller than the conventional one, the jig The displacement of the plate 40 with respect to 150 can be sufficiently suppressed. Therefore, the heat exchanger 1 can reduce the size of the plate 40 and the open end 11 of the tank 10.
　また、プレート４０の枠部４５は、熱交換器１のコア３０に接合される。 Further, the frame portion 45 of the plate 40 is joined to the core 30 of the heat exchanger 1.
　上記構成により、熱交換器１は、プレート４０の枠部４５がコア３０から突出する寸法が小さく抑えられ、小型化が図れる。 With the above configuration, the heat exchanger 1 can be reduced in size because the size of the frame portion 45 of the plate 40 protruding from the core 30 is kept small.
　また、プレート４０の枠部４５は、コア３０に接合され、コア３０との間に開口端部１１を収容する溝３２を形成する。 Further, the frame portion 45 of the plate 40 is joined to the core 30, and a groove 32 for accommodating the open end portion 11 is formed between the frame portion 45 and the core 30.
　上記構成により、枠部４５をＬ字形の断面形状を有するものとして、コア３０から枠部４５が突出する寸法を小さく抑えられる。よって、熱交換器１は、プレート４０及びタンク１０の開口端部１１の小型化が図れる。 With the above configuration, the size of the frame 45 protruding from the core 30 can be kept small by assuming that the frame 45 has an L-shaped cross-sectional shape. Therefore, the heat exchanger 1 can reduce the size of the plate 40 and the open end 11 of the tank 10.
　なお、プレート４０の枠部４５は、Ｌ字形の断面形状を有するものに限らず、Ｓ字形の断面形状を有するものであってもよい。この場合、溝３２は、コア３０を介さず、プレート４０のみによって形成される。 Note that the frame portion 45 of the plate 40 is not limited to having an L-shaped cross-sectional shape, and may have an S-shaped cross-sectional shape. In this case, the groove 32 is formed only by the plate 40 without using the core 30.
　以上、本発明の実施形態について説明したが、上記実施形態は本発明の適用例の一部を示したに過ぎず、本発明の技術的範囲を上記実施形態の具体的構成に限定する趣旨ではない。 The embodiment of the present invention has been described above. However, the above embodiment only shows a part of application examples of the present invention, and the technical scope of the present invention is limited to the specific configuration of the above embodiment. Absent.
　本実施形態では、タンク１０は、流路を形成する流路部材である。なお、これに限らず、タンク１０は、気体または液体等を溜める容器として設けられる容器であってもよい。 In the present embodiment, the tank 10 is a flow path member that forms a flow path. However, the present invention is not limited thereto, and the tank 10 may be a container provided as a container for storing gas or liquid.
　本実施形態では、プレート４０は、開口端部１１に沿って枠状（環状）に延在する単一の部材である。なお、これに限らず、プレート４０は、開口端部１１に沿って複数に分割された部材であってもよい。 In this embodiment, the plate 40 is a single member that extends in a frame shape (annular shape) along the opening end 11. In addition, the plate 40 may be a member divided into a plurality along the opening end portion 11.
　本実施形態では、延在部４２は、開口端部１１のまわりに沿うように折り曲げられる加締め部材である。なお、これに限らず、延在部４２は、開口端部１１のまわりに沿うように予め形成された部材であってもよい。この場合、延在部４２が、弾性変形をして穴５０をタンク１０の突起１５に係合することで、加締め固定が行われる。 In the present embodiment, the extending portion 42 is a caulking member that is bent along the periphery of the opening end portion 11. In addition, the extension part 42 may be a member formed in advance so as to extend around the opening end part 11. In this case, the extending portion 42 is elastically deformed to engage the hole 50 with the protrusion 15 of the tank 10, thereby performing caulking and fixing.
　本発明のタンク取り付け構造は、車両に搭載される熱交換器に好適であるが、これに限らず、熱交換器以外にも適用できる。 The tank mounting structure of the present invention is suitable for a heat exchanger mounted on a vehicle, but is not limited to this and can be applied to other than a heat exchanger.
