このような多穴管構造のチューブＡは押出し成形によっ
て製作されるが、多穴管の押出し成形が技術的、工業的
に可能な材料がアルミニウムに限られることから、チュ
ーブ八にはアルミニウムのみが用いられている。Tube A with such a multi-hole tube structure is manufactured by extrusion molding, but aluminum is the only material that is technically and industrially possible to extrude a multi-hole tube, so aluminum is the only material available for tube 8. It is used.
ところが、よく知られているようにアルミニウムはろう
付けによる他の金属との接合性が悪いため、アルミニウ
ム製多穴チューブＡに対しては、フィンＢについても同
じアルミニウムしか使用できなかった。However, as is well known, aluminum has poor bondability with other metals by brazing, so for the multi-hole aluminum tube A, only the same aluminum could be used for the fins B.
従って、耐食性や伝熱性等の必要から、フィンＢに銅や
ニッケル等のアルミニウム以外の金属材料を使用したい
場合には、接合性の観点からチューブ材料としてアルミ
ニウム以外の金属材料を用いざるを得なかった。Therefore, if you want to use a metal material other than aluminum, such as copper or nickel, for the fin B due to the need for corrosion resistance or heat conductivity, you have no choice but to use a metal material other than aluminum as the tube material from the viewpoint of bondability.

施されていないのが実情である。It is conceivable to flatten a round pipe and then insert reinforcing ribs into the flattened pipe and join them together, but this has not been carried out because it is poor in manufacturing efficiency and impractical in terms of cost. is the reality.
また、アルミニウム同士であっても、低温下での軟ろう
付け（半田付け）では接合性が悪いため、接合手段とし
ては高温下での硬ろう付げに限られてしまうという問題
もあった。Furthermore, even when aluminum is bonded together, soft brazing (soldering) at low temperatures has poor bonding properties, so there is a problem in that the joining method is limited to hard brazing at high temperatures.
