Description

【０００１】
【発明の属する技術分野】
本発明は、熱交換器の金属製タンクに樹脂製パイプを接続する接続構造に関する。
【０００２】
【従来の技術】
金属製タンクと樹脂製パイプとの接続構造は、樹脂製タンクと金属製チューブプレートとの接続構造を利用することができる。図４はその例で、タンク１のパイプ接続口１ａに金属製段付カラー状の接続用カップ２の先端部を嵌着して、タンク１，接続用カップ２間をろう付け固定する。接続用カップ２の外周には予めスリットを形成しておき、そのスリットより後端面にカシメ部８を設けておく。
次に樹脂製パイプ４は、その先端部外周にフランジ部３を有すると共に、そのフランジ部３よりもさらに先端に環状溝11を形成しておく。そしてその環状溝11にＯリング10を嵌着し、樹脂製パイプ４の先端部を接続用カップ２に嵌着する。次いでカシメ部８を塑性変形することにより、樹脂製パイプ４を接続用カップ２に固定するものである。
【０００３】
【発明が解決しようとする課題】
このように樹脂製パイプ４の先端部外周に環状溝11を形成するには、図５の如く、そのパイプ製造用射出成形の金型において、樹脂製パイプ４の先端部を半径方向に分割する第１の金型12と第２の金型13を設ける必要がある。すると、その環状溝11にはパーティングライン15が形成される。そのため、そこにＯリング10を被嵌するとパーティングライン15の僅かな凸部によって気密性が損なわれるおそれがある。そこで本発明は、係る問題点を解決することを課題とする。
【０００４】
【課題を解決するための手段】
請求項１に記載の本発明は、円形なパイプ取付口(1a)を有する金属製タンク(1) と、
そのパイプ取付口(1a)に液密に接続固定されるリング状の金属製の接続用カップ(2) と、
その接続用カップ(2) に先端部が嵌入し、その先端部外周に突設されたフランジ部(3) の後端面(3a)で、前記接続用カップ(2) にカシメ固定される樹脂製パイプ(4) と、を有する樹脂製パイプとタンクとの接続構造において、
前記接続用カップ(2) は、前記パイプ接続口(1a)の開口直径より大なる直径の着座用フランジ部(5) がその中間部外周に折り返し曲折されると共に、その着座用フランジ部(5) の先端側がそのパイプ接続口(1a)に挿入されるタンク挿入部(6) を有し且つ、その先端縁に内フランジ部(7) が曲折形成され、前記着座用フランジ部(5) の後端側の縁部にカシメ部(8) が形成され、
前記樹脂製パイプ(4) は、金型を用いた射出成形により形成され、前記フランジ部(3) の先端縁部に直径が段付に縮小するＯリング嵌着部(9) が形成され、そのフランジ部(3) の中間部および後端部が接続用カップ(2) の内周に整合し、
そのＯリング嵌着部(9) の外周と前記接続用カップ(2) の内周面および前記内フランジ部(7) とで囲まれたＯリング保持部(6a)にシール用のＯリング(10)が圧入され、
樹脂製パイプ(4) の先端面(4a)が接続用カップ(2) の内フランジ部(7) に着座された状態で、カシメ部(8) を樹脂製パイプ(4) の軸線側に折り曲げることにより、その端縁がフランジ部(3) の後端面(3b)に圧着して接続され、
前記樹脂製パイプ(4) の前記先端部のＯリング嵌着部(9) の外周には、環状の溝が設けられていないことを特徴とする樹脂製パイプとタンクとの接続構造である。
【０００６】
【発明の実施の形態】
次に、図面に基づいて本発明の実施の形態につき説明する。
図１は本発明の樹脂製パイプとアルミニューム製タンクとの接続構造の分解斜視図であり、図２はその取付け状態を示す縦断面図である。
この樹脂製パイプとタンクとの接続構造は、パイプ接続口１ａを有するタンク１と、そのパイプ接続口１ａにろう付け等の手段で液密に固定されるアルミニューム製の接続用カップ２と、その接続用カップ２にＯリング10を介して先端部が嵌着され、接続用カップ２のカシメ部８によってカシメ固定される樹脂製パイプ４とを有する。
【０００７】
接続用カップ２は、その中間部外周に着座用フランジ部５が折り返し曲折され、その着座用フランジ部５の直径がパイプ接続口１ａの開口直径より大に形成されている。そして着座用フランジ部５の先端側にパイプ接続口１ａに整合するタンク挿入部６を有し且つ、その先端縁に内フランジ部７が曲折形成されている。着座用フランジ部５の後端部側の縁部には、カシメ部８が形成されている。このカシメ部８は、接続用カップ２の後端縁から逆Ｔ字状に形成されたスリット16に隣接して設けられ、そのスリット16によってその部分の塑性変形が容易になる構造を有する。
このようにしてなる接続用カップ２は、予めタンク１にろう付け接合される。このとき図２の如く、タンク１とチューブプレート17との間及び、チューブプレート17とチューブ18との間並びに、図示しないチューブ18とフィンとの間が一体的にろう付け固定される。
【０００８】
次に、樹脂製パイプ４はその先端部にフランジ部３が突設形成され、そのフランジ部３の先端縁部に直径が段付に縮小するＯリング嵌着部９が形成されている。フランジ部３の中間部及び後端部外周は、接続用カップ２の内周に整合する。そして、Ｏリング嵌着部９の外周には、従来型樹脂製パイプのような環状の溝は設けられていない。
そこで、樹脂製パイプ４のＯリング嵌着部９にＯリング10が被嵌され、それらが接続用カップ２内に嵌着される。そして樹脂製パイプ４の先端面４ａを内フランジ部７に着座させ、カシメ部８を樹脂パイプ４の軸線側に折り曲げることにより、その端縁をフランジ部３の後端面３ａに圧着して接続構造を完成する。
【０００９】
なお、符号６ａはＯリング保持部であり、樹脂製パイプ４のＯリング嵌着部９の外周と接続用カップ２の内周面及び内フランジ部７との間で囲まれた部分である。そしてこのＯリング保持部６ａにＯリング10が圧入され、液密構造が形成される。
【００１０】
次に、図３は本発明の他の実施の形態を示し、この例が図２のそれと異なる点はカシメ部８のみである。この例では、接続用カップ２の後端部に形成されたスリット16がフランジ部３に整合する位置で直線状に形成され、それが定間隔に断続的に設けられ、そのスリット16の上部側が樹脂製パイプ４の中心側に曲折され、そのカシメ部８の縁部でフランジ部３の後端面３ａが止着されるものである。
【００１１】
【発明の作用・効果】
本発明の樹脂製パイプとタンクとの接続構造によれば、樹脂製パイプ４にフランジ部３とＯリング嵌着部９とを段付状に形成すると共に、接続用カップ２の中間部に着座用フランジ部５を設け、先端部に内フランジ部７を形成し、後端部にカシメ部８を設けることにより、比較的簡単に信頼性の高い接続構造が形成できる。
特に、カシメ固定の際に、樹脂製パイプ４の先端面4aが、接続用カップ２の内フランジ部７に着座されるため、樹脂性パイプ４の安定性よく、Ｏリング10の圧着量が厳密に特定され、信頼性の高い接続構造が形成できる。これらは、樹脂性パイプ４が軸方向に移動しないように、そのフランジ部３と先端面4aとが、カシメ部８と内フランジ７との各平坦な面で確実に位置決めされるからである。そして省スペースで取扱い易いものとなり得る。
また、樹脂製パイプ４の外周のＯリング嵌着部には環状の溝が設けられていない構造であるため、Ｏリング10によるシールの信頼性を高めることができる。即ち、金型を用いた射出成形により形成される樹脂製パイプ４において、従来の環状溝を設けた場合に樹脂製パイプ４の溝内に生じるパーティングラインの発生を防止し、信頼性の高いシール構造を提供できる。

[0006]
DETAILED DESCRIPTION OF THE INVENTION
Next, embodiments of the present invention will be described with reference to the drawings.
FIG. 1 is an exploded perspective view of a connection structure between a resin pipe and an aluminum tank according to the present invention, and FIG. 2 is a longitudinal sectional view showing an attachment state thereof.
The connection structure between the resin pipe and the tank includes a tank 1 having a pipe connection port 1a, an aluminum connection cup 2 fixed to the pipe connection port 1a by a means such as brazing, and the like. The connecting cup 2 has a resin pipe 4 having a tip end portion fitted through an O-ring 10 and fixed by a caulking portion 8 of the connecting cup 2.
[0007]
The connecting cup 2 has a seating flange portion 5 folded back at the outer periphery of the intermediate portion, and the diameter of the seating flange portion 5 is larger than the opening diameter of the pipe connection port 1a. A tank insertion portion 6 aligned with the pipe connection port 1a is provided on the distal end side of the seating flange portion 5, and an inner flange portion 7 is bent at the distal end edge. A caulking portion 8 is formed on the edge portion on the rear end side of the seating flange portion 5. The caulking portion 8 is provided adjacent to a slit 16 formed in an inverted T shape from the rear end edge of the connection cup 2, and has a structure that facilitates plastic deformation of the portion by the slit 16.
The connection cup 2 thus formed is brazed to the tank 1 in advance. At this time, as shown in FIG. 2, the tank 1 and the tube plate 17, the tube plate 17 and the tube 18, and the tube 18 and the fin (not shown) are integrally brazed and fixed.
[0008]
Next, the resin pipe 4 has a flange portion 3 projectingly formed at the tip thereof, and an O-ring fitting portion 9 whose diameter is reduced stepwise is formed at the tip edge of the flange portion 3. The outer periphery of the intermediate portion and the rear end of the flange portion 3 is aligned with the inner periphery of the connection cup 2. And the annular groove like the conventional resin pipe is not provided in the outer periphery of the O-ring fitting part 9.
Therefore, an O-ring 10 is fitted on the O-ring fitting portion 9 of the resin pipe 4, and these are fitted into the connection cup 2. Then, the front end surface 4a of the resin pipe 4 is seated on the inner flange portion 7, and the crimping portion 8 is bent toward the axis of the resin pipe 4 so that the end edge thereof is crimped to the rear end surface 3a of the flange portion 3. To complete.
[0009]
Reference numeral 6 a denotes an O-ring holding portion, which is a portion surrounded by the outer periphery of the O-ring fitting portion 9 of the resin pipe 4 and the inner peripheral surface of the connection cup 2 and the inner flange portion 7. Then, the O-ring 10 is press-fitted into the O-ring holding portion 6a to form a liquid tight structure.
[0010]
Next, FIG. 3 shows another embodiment of the present invention, and this example is different from that of FIG. In this example, the slit 16 formed at the rear end of the connecting cup 2 is formed in a straight line at a position aligned with the flange portion 3, and is provided intermittently at an interval, and the upper side of the slit 16 is The resin pipe 4 is bent toward the center side, and the rear end surface 3a of the flange portion 3 is fixed to the edge portion of the caulking portion 8.
[0011]
[Operation and effect of the invention]
According to the connection structure between the resin pipe and the tank of the present invention, the flange portion 3 and the O-ring fitting portion 9 are formed in the resin pipe 4 in a stepped shape, and is seated on the intermediate portion of the connection cup 2. By providing the flange portion 5, forming the inner flange portion 7 at the front end portion, and providing the caulking portion 8 at the rear end portion, a highly reliable connection structure can be formed relatively easily.
In particular, when the caulking is fixed, the distal end surface 4a of the resin pipe 4 is seated on the inner flange portion 7 of the connection cup 2, so that the resin pipe 4 is stable and the O-ring 10 is tightly crimped. A highly reliable connection structure can be formed. This is because the flange portion 3 and the tip surface 4a are reliably positioned on the flat surfaces of the crimping portion 8 and the inner flange 7 so that the resin pipe 4 does not move in the axial direction. And it can be easy to handle with space saving.
Further, since the O-ring fitting portion on the outer periphery of the resin pipe 4 is not provided with an annular groove, the reliability of the seal by the O-ring 10 can be improved. That is, in the resin pipe 4 formed by injection molding using a mold , the occurrence of a parting line generated in the groove of the resin pipe 4 when a conventional annular groove is provided is prevented and the reliability is high. A seal structure can be provided.
