Claims (1)
と、該フイン１に貫通した多数の円形チユーブ２
と、により熱交換器のコアを形成したものにおい
て、前記プレートフイン１の長さにほぼ等しい部
分だけヘツダーパイプ３の断面外周を半円に形成
して塑性変形してそこに平坦面４を設け、他の部
分は断面円形に形成し、夫々の前記チユーブ２の
軸線に整合する位置で前記平坦面４に多数のチユ
ーブ孔を穿設し、夫々の該チユーブ孔に軸線が直
線をなす多数の短管５の一端を該短管が平坦面４
に垂直に挿通して、夫々の該挿通部をろう付け固
定し、夫々の前記チユーブ２の開口端を拡開して
そこに拡開部６を形成し、該拡開部６に夫々の前
記短管５の他端を挿入して該挿入部をろう付け固
定したことを特徴とする熱交換器。 A large number of plate fins 1 arranged in parallel with small gaps
and a large number of circular tubes 2 penetrating the fin 1.
The core of the heat exchanger is formed by forming the core of the heat exchanger by forming the cross-sectional outer periphery of the header pipe 3 into a semicircle in a portion approximately equal to the length of the plate fin 1 and plastically deforming it to provide a flat surface 4 there; The other portion is formed to have a circular cross section, and a number of tube holes are bored in the flat surface 4 at positions aligned with the axis of each of the tubes 2, and each of the tube holes has a number of short holes whose axes are straight. One end of the tube 5 is connected to the flat surface 4 of the short tube.
The tubes 2 are inserted perpendicularly into the tubes 2 and the respective insertion portions are brazed and fixed. A heat exchanger characterized in that the other end of the short tube 5 is inserted and the inserted portion is fixed by brazing.
