本発明は熱交換器に用いられるフィン付チューブ形熱交
換器の製造方法に関するものである。DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a method for manufacturing a finned tube heat exchanger used in a heat exchanger.
従来のこの種熱交換器の製造方法を第１図・第２図によ
り説明する。A conventional method for manufacturing this type of heat exchanger will be explained with reference to FIGS. 1 and 2.
リボン状の平板素材に塑性加工を施し、第１図に示すよ
うな断面形状のフィン１とする。A ribbon-shaped flat plate material is subjected to plastic working to form a fin 1 having a cross-sectional shape as shown in FIG.
このフィン１はチューブ２に巻きつける部分と他の側で
板厚を変化させ、展開長において巻きつける部分と他の
側に長さの差をつけて第２図に示す如くチューブ２に巻
付ける。This fin 1 is wound around the tube 2 by changing the thickness between the part to be wrapped around the tube 2 and the other side, and with a difference in length between the part to be wrapped and the other side in the unfolded length, as shown in Fig. 2. .
かかるフィン付チューブ２に巻きつける部分と他の側に
塑性加工を施して板厚を変化させ、展開長において長さ
に差をつけながらチューブ２に巻きつけるので、強力な
矯正ロールと複雑な機構の設備を必要とし製造原価を高
くしてきた。The part to be wrapped around the finned tube 2 and the other side are plastically worked to change the plate thickness, and the tube 2 is wrapped around the tube 2 while making a difference in length at the unfolded length, which requires powerful straightening rolls and a complicated mechanism. This has resulted in high production costs due to the need for additional equipment.
又、塑性加工による材料の変形には限界があるので、展
開長における巻きつける側と他の側の長さの差の範囲は
材料と加工条件により決められる。Furthermore, since there is a limit to the deformation of the material by plastic working, the range of the difference in length between the wrapped side and the other side in the developed length is determined by the material and processing conditions.
このだめ、フィン１の外径は一定の範囲に決められ、し
かも巻きつけるチューブと同心の円形のものしか得られ
ないので応用範囲が限られている。Unfortunately, the outer diameter of the fins 1 is determined within a certain range, and the range of applications is limited because only circular ones can be obtained that are concentric with the tube around which they are wound.
本発明はかかる欠陥を解消せんとしてなされたものであ
る。The present invention has been made in an attempt to eliminate such deficiencies.
金属製チューブ６の外径に略一致した内径を有する厚肉
の筒状素材３の底面の半径方向にバイト４を当てて旋削
し、バイト４にフィン５の必要板厚だけの送りをかけて
連続切屑状のコイルに切離してフィン５を作成し、該フ
ィン５の内径部に金属チューブ６を通して固定してなる
フィン付チューブ形熱交換器の製造方法を提供せんとす
るものである。Turning is performed by applying a cutting tool 4 in the radial direction of the bottom surface of a thick-walled cylindrical material 3 having an inner diameter that approximately matches the outer diameter of the metal tube 6, and applying a feed to the cutting tool 4 by the required plate thickness of the fin 5. It is an object of the present invention to provide a method for manufacturing a finned tube heat exchanger in which fins 5 are created by cutting into continuous chip-like coils, and metal tubes 6 are passed and fixed to the inner diameter portions of the fins 5.
以下、本発明を図に示す一実施例で説明する。The present invention will be explained below with reference to an embodiment shown in the drawings.
第３図において、金属製チューブ６の外径に略一致した
内径を有する厚肉の筒状素材３を旋削加工機械に取付け
て矢の方向に回転させ、この素材３の底面半径方向にバ
イト４を当てて旋削し、バイト４にフィン５の必要板厚
だけの送りをかけて第４図の如く連続切屑状のコイルに
切離してフィンが連続して得られるものである。In FIG. 3, a thick-walled cylindrical material 3 having an inner diameter that approximately matches the outer diameter of a metal tube 6 is attached to a turning machine and rotated in the direction of the arrow, and a cutting tool 4 is attached to the bottom surface of the material 3 in the radial direction. The fins are turned by turning the fins, and by feeding the cutting tool 4 by the necessary thickness of the fins 5, the fins are cut into continuous chip-like coils as shown in FIG.
該フィン５に所要の金属チューブ６を挿入して固定した
ものが第５図である。FIG. 5 shows the fin 5 in which a required metal tube 6 is inserted and fixed.
この固定方法としては、チューブ６を拡管する方法、ろ
う付けする方法、接着剤で接着する方法がある。This fixing method includes a method of expanding the tube 6, a method of brazing, and a method of bonding with an adhesive.
尚、厚肉の筒状素材３の内径をチューブ６の外径になる
ように選べば、フィン５の外周の形状は厚肉の筒状素材
３の外径の形状を選ぶことにより自由に必要な形状が得
られる。Note that if the inner diameter of the thick-walled cylindrical material 3 is selected to match the outer diameter of the tube 6, the shape of the outer periphery of the fin 5 can be freely determined by selecting the shape of the outer diameter of the thick-walled cylindrical material 3. A shape can be obtained.
又、フィン５の板厚はバイト４の送りを自由に選ぶこと
により必要な板厚のフィンを得ることができる。Further, the thickness of the fin 5 can be determined by freely selecting the feed of the cutting tool 4 to obtain a fin of the required thickness.
本発明によれば、設備費は安く作業性が良好になり、安
定した製品が得られるものである。According to the present invention, equipment costs are low, workability is good, and stable products can be obtained.
