熱交換器は、本体の取付位置や他部材との相互
位置関係により、チユーブの接続端部の位置や方
向が制約されることがある。[Detailed Description of the Invention] In a heat exchanger, the position and direction of the connecting end of the tube may be restricted depending on the mounting position of the main body and the mutual positional relationship with other members.

の一端を接続し、その他端に、接続金具3を取付
けていた。従つて、加工が面倒で、高価となつ
た。 In a meandering type heat exchanger in which a flat tube with an oval cross section is bent in a meandering manner and fins are provided between them, the connection fittings at the inlet and outlet of the tube must be deviated laterally from the axis of the tube. Since it is technically difficult to bend the tube in the flat direction when the tube 1 is required, conventionally, as shown in FIGS. Bent circular pipe 2
was connected at one end, and a connecting fitting 3 was attached to the other end. Therefore, processing is troublesome and expensive.
なお、4はフイン、5は、パイプ2の接続部で
ある。 In addition, 4 is a fin, and 5 is a connection part of the pipe 2.
本考案は、上述の欠点を解消した熱交換器にお
ける偏平チユーブの接続端部の構造に関するもの
で、第3図乃至第5図に基いて、具体的に説明す
る。 The present invention relates to a structure of a connecting end of a flat tube in a heat exchanger that eliminates the above-mentioned drawbacks, and will be specifically explained with reference to FIGS. 3 to 5.
チユーブ1と同様の長円形断面の偏平なチユー
ブ11の端部11bは、移行部11aを介して、
チユーブ11の中心軸線lまわりに90゜捩られる
とともに、側方へ偏倚され、これによつて、上述
の円形パイプ2を使用した場合と同様の効果を得
ている。 An end portion 11b of a flat tube 11 having an oval cross section similar to the tube 1 is connected to
The tube 11 is twisted by 90 degrees around the central axis l and biased laterally, thereby achieving the same effect as when using the circular pipe 2 described above.
従つて、この熱交換器は、従来の熱交換器にお
ける円形パイプ2とその接続部5が不要となり、
またチユーブ端部11aの捩り加工が容易である
ので、熱交換器を安価に製作することができる。 Therefore, this heat exchanger eliminates the need for the circular pipe 2 and its connection part 5 in the conventional heat exchanger.
Further, since the tube end portion 11a can be easily twisted, the heat exchanger can be manufactured at low cost.
12は、チユーブ11の端部11bに取付けら
れた接続金具、13は、上記フイン4と同様のフ
インである。 12 is a connecting fitting attached to the end portion 11b of the tube 11, and 13 is a fin similar to the fin 4 described above.
本考案は、このように、偏平チユーブの端部1
1bを軸線まわりに90゜捩ることにより、チユー
ブの端部11bを、元来は、屈曲困難な側方へ容
易に偏倚させられており、チユーブ端部の取付位
置を制約される自動車用ラジエータ等に好適であ
る。 In this way, the present invention provides an end portion 1 of the flat tube.
By twisting the tube end 11b by 90 degrees around the axis, the tube end 11b can be easily deflected to the side, which is originally difficult to bend, and the mounting position of the tube end is restricted in automobile radiators, etc. suitable for
