以下、本発明を実施するための最良の形態を、図面を参照して説明する。   The best mode for carrying out the present invention will be described below with reference to the drawings.

図1及び図2は、本発明の第1実施形態における分岐管1の斜視図である。分岐管1は、出口管2(第1の管)と、入口管3(第2の管)と、を備えている。分岐管1は、入口管3における流体(例えば、空気、油、水等)の流れを出口管2によって2つの流れに分岐させるものである。出口管2は、開口部2aを備えている。開口部2aは出口管2の一部(出口管2における一端2bと他端2cの間)に形成されている。開口部2aには、特殊なバーリング加工が施され、管の途中で円周状に外側に突出している。出口管2は、一端2bと他端2cとの間で、図1に示すようにL字状、または、U字状に屈曲した構成となっている。   1 and 2 are perspective views of the branch pipe 1 in the first embodiment of the present invention. The branch pipe 1 includes an outlet pipe 2 (first pipe) and an inlet pipe 3 (second pipe). The branch pipe 1 branches the flow of fluid (for example, air, oil, water, etc.) in the inlet pipe 3 into two flows by the outlet pipe 2. The outlet pipe 2 has an opening 2a. The opening 2a is formed in a part of the outlet pipe 2 (between one end 2b and the other end 2c in the outlet pipe 2). The opening 2a is subjected to a special burring process and protrudes outward in a circumferential manner in the middle of the pipe. The outlet pipe 2 is configured to be bent in an L shape or a U shape as shown in FIG. 1 between one end 2b and the other end 2c.

一方、入口管3は、接合部3aを備えている。接合部3aは、入口管3における端部3bに形成されている。入口管3の接合部3aは、出口管2の開口部2aにろう付けによって接合される(図2参照)。この接合部3aは、円筒部3cと、延在部3dとを備えている。円筒部3cは、その内周面にて出口管2の開口部2aと嵌合する。延在部3dは、公知のフレア加工によって円筒部3cの端部に形成される。延在部3dは、円筒部3cの端部から径方向に延在し、ろう付けによって出口管2の外周面に接合される。   On the other hand, the inlet pipe 3 includes a joint 3a. The joint 3 a is formed at the end 3 b of the inlet pipe 3. The joint 3a of the inlet pipe 3 is joined to the opening 2a of the outlet pipe 2 by brazing (see FIG. 2). The joint part 3a includes a cylindrical part 3c and an extending part 3d. The cylindrical portion 3c is fitted to the opening 2a of the outlet pipe 2 on the inner peripheral surface thereof. The extending part 3d is formed at the end of the cylindrical part 3c by a known flare process. The extending portion 3d extends in the radial direction from the end portion of the cylindrical portion 3c, and is joined to the outer peripheral surface of the outlet pipe 2 by brazing.

出口管2及び入口管3は、図3に示す様に、外径の異なる複数の部位を有している。これらの部位は必要に応じて切断可能であって、これにより、出口管2及び入口管3には、さまざまな内径の管(直管)が接続可能である。   As shown in FIG. 3, the outlet pipe 2 and the inlet pipe 3 have a plurality of portions having different outer diameters. These portions can be cut as necessary, and thereby, the outlet pipe 2 and the inlet pipe 3 can be connected to pipes having various inner diameters (straight pipes).

本実施形態に係る分岐管1によれば、入口管3の接合部3aが出口管2の開口部2aに接合され、入口管3と出口管2とが直接接合されるので、分岐管1における接合箇所が減る。また、入口管3と出口管2とを接合するための部材を別個に設ける必要がなく、2本の管だけで分岐管1が構成されるので、分岐管1における部品点数も減る。以上により、分岐管1の製造に係るコストを低減できる。   According to the branch pipe 1 according to the present embodiment, the joint 3a of the inlet pipe 3 is joined to the opening 2a of the outlet pipe 2, and the inlet pipe 3 and the outlet pipe 2 are directly joined. There are fewer joints. Further, it is not necessary to separately provide a member for joining the inlet pipe 3 and the outlet pipe 2, and the branch pipe 1 is constituted by only two pipes, so that the number of parts in the branch pipe 1 is reduced. As described above, the cost for manufacturing the branch pipe 1 can be reduced.

また、入口管3における接合部3aの延在部3dがろう付けによって出口管2の外周面に接合されるので、入口管3と出口管2との接合面積(ろうの濡れ面積)が十分に確保され、分岐管1における接合箇所の信頼性(強度、耐圧性、気密性)が向上する。   Moreover, since the extension part 3d of the joining part 3a in the inlet pipe 3 is joined to the outer peripheral surface of the outlet pipe 2 by brazing, the joining area between the inlet pipe 3 and the outlet pipe 2 (wax wet area) is sufficient. As a result, the reliability (strength, pressure resistance, and airtightness) of the joint portion in the branch pipe 1 is improved.

また、出口管2の開口部2aにはバーリング加工が施されているので、入口管3の接合部3aと出口管2の開口部2a(出口管2の外周面)をろう付けによって接合する際に、ろうが開口部2aを介して出口管2の内部に入るのを防止することができる。   In addition, since the opening 2a of the outlet pipe 2 is subjected to burring processing, the joint 3a of the inlet pipe 3 and the opening 2a of the outlet pipe 2 (outer peripheral surface of the outlet pipe 2) are joined by brazing. In addition, the wax can be prevented from entering the inside of the outlet pipe 2 through the opening 2a.

次に、第2実施形態について、図4を参照して説明する。図4において、分岐管11は、出口管12(第1の管)と、入口管13(第2の管)と、を備えている。出口管12は、開口部12aを備えている。開口部12aは、出口管12における一端12bと他端12cの間に形成されている。開口部12aには、公知のバーリング加工が施されている。出口管12は、一端12bと他端12cとの間で、L字状(図4示)やU字状に曲げられる。   Next, a second embodiment will be described with reference to FIG. In FIG. 4, the branch pipe 11 includes an outlet pipe 12 (first pipe) and an inlet pipe 13 (second pipe). The outlet pipe 12 includes an opening 12a. The opening 12a is formed between one end 12b and the other end 12c of the outlet pipe 12. The opening 12a is subjected to a known burring process. The outlet pipe 12 is bent into an L shape (shown in FIG. 4) or a U shape between one end 12b and the other end 12c.

入口管13は、接合部13aを備えている。接合部13aは、入口管13における端部13bに形成されている。入口管13の接合部13aは、出口管12の開口部12aにろう付けによって接合される。接合部13aは、円筒部13cと、一対の延在部13dとを備えている。円筒部13cは、その内周面にて出口管12の開口部12aと嵌合する。延在部13dは、円筒部13cの端部をU字状にカットすることによって形成される。延在部13dは、出口管12を挟むように円筒部13cの端部から軸方向に延在し、ろう付けによって出口管12の外周面に接合される。   The inlet pipe 13 includes a joint portion 13a. The joint portion 13 a is formed at the end portion 13 b of the inlet pipe 13. The joint 13a of the inlet pipe 13 is joined to the opening 12a of the outlet pipe 12 by brazing. The joint portion 13a includes a cylindrical portion 13c and a pair of extending portions 13d. The cylindrical portion 13c is fitted to the opening 12a of the outlet pipe 12 on the inner peripheral surface thereof. The extending portion 13d is formed by cutting an end portion of the cylindrical portion 13c into a U shape. The extending part 13d extends in the axial direction from the end of the cylindrical part 13c so as to sandwich the outlet pipe 12, and is joined to the outer peripheral surface of the outlet pipe 12 by brazing.

次に、図5を参照して、第3実施形態における分岐管11について説明する。図5に示す第3実施形態では、(a)に示す如く入口管13の端部13eを円筒状として、円筒状の端部13eを出口管の開口部12aに接合する構成としている。この様な接合方法を取ることにより、第2実施形態と同様な効果を得ることも可能である。   Next, the branch pipe 11 in the third embodiment will be described with reference to FIG. In the third embodiment shown in FIG. 5, the end 13e of the inlet pipe 13 is cylindrical as shown in FIG. 5A, and the cylindrical end 13e is joined to the opening 12a of the outlet pipe. By adopting such a joining method, it is possible to obtain the same effect as in the second embodiment.

以上の説明によれば、本実施形態の分岐管11では、入口管13の接合部13aが出口管12の開口部12aに接合され、入口管13と出口管12とが直接接合されるので、分岐管11における接合箇所が減るものとなる。また、入口管13と出口管12とを接合するための接合部材を別個に設ける必要がなく、2本の管だけで分岐管11が構成されるので、分岐管11における部品点数も削減することができる。以上により、分岐管11の製造に係るコストを低減することができる。   According to the above description, in the branch pipe 11 of the present embodiment, the joint portion 13a of the inlet pipe 13 is joined to the opening 12a of the outlet pipe 12, and the inlet pipe 13 and the outlet pipe 12 are directly joined. The number of joints in the branch pipe 11 is reduced. Further, it is not necessary to separately provide a joining member for joining the inlet pipe 13 and the outlet pipe 12, and the branch pipe 11 is configured by only two pipes, so that the number of parts in the branch pipe 11 is also reduced. Can do. As described above, the cost for manufacturing the branch pipe 11 can be reduced.

また、入口管13における接合部13aの延在部13dがろう付けによって出口管12の外周面に接合されるので、入口管13と出口管12との接合面積(ろうの濡れ面積)が十分に確保され、分岐管11における接合箇所の信頼性(強度、耐圧性、気密性)が向上する。   In addition, since the extending portion 13d of the joint portion 13a in the inlet pipe 13 is joined to the outer peripheral surface of the outlet pipe 12 by brazing, the joint area (wax wet area) of the inlet pipe 13 and the outlet pipe 12 is sufficient. It is ensured, and the reliability (strength, pressure resistance, and airtightness) of the joint portion in the branch pipe 11 is improved.

また、出口管12の開口部12aにはバーリング加工が施されているので、入口管13の接合部13aと出口管12の開口部12a(出口管12の外周面)をろう付けによって接合する際に、ろうが開口部12aを介して出口管12の内部に入るのを防止することができる。   In addition, since the opening 12a of the outlet pipe 12 is subjected to burring processing, the joint 13a of the inlet pipe 13 and the opening 12a of the outlet pipe 12 (outer peripheral surface of the outlet pipe 12) are joined by brazing. In addition, the wax can be prevented from entering the inside of the outlet pipe 12 through the opening 12a.

実施例に記載された分岐管1或いは分岐管11は、図6に示すように空気調和装置における室外熱交換器17と室内熱交換器16との間を接続する冷媒管15に用いることができる。図6では、冷媒管15は、結合用直管14に分岐管1或いは分岐管11を接続し分岐している。この場合、分岐管1或いは分岐管11の大きさ、長さを一定とし、結合用直管14で長さを調節することができる。また、分岐管1或いは分岐管11自身が冷媒管15となり直接、複数の室外熱交換器と複数の室内熱交換器を簡便に接続しても良い。この場合、更に部品点数を削減することができる。   The branch pipe 1 or the branch pipe 11 described in the embodiment can be used for the refrigerant pipe 15 that connects between the outdoor heat exchanger 17 and the indoor heat exchanger 16 in the air conditioner as shown in FIG. . In FIG. 6, the refrigerant pipe 15 is branched by connecting the branch pipe 1 or the branch pipe 11 to the coupling straight pipe 14. In this case, the size and length of the branch pipe 1 or the branch pipe 11 can be made constant, and the length can be adjusted by the coupling straight pipe 14. Further, the branch pipe 1 or the branch pipe 11 itself becomes the refrigerant pipe 15 and may directly connect a plurality of outdoor heat exchangers and a plurality of indoor heat exchangers. In this case, the number of parts can be further reduced.
