にろう付によって、接合されている。The through pipe 13 is inserted into each through hole 9.10.14 formed in the body 2 and the fins 3. The insertion direction is specified, and the through pipe 13 is inserted through the through hole 9 of the body 2 (the through hole through which the burring part 11 faces inside the body 2). Before being inserted into each through hole 9.10.14, the through pipe 13 is inserted into each through hole 9.10.
The inner diameter is slightly smaller than the inner diameter of 14. After being inserted into the through hole 9.10.14, the diameter of the through pipe 13 is enlarged, and the outer periphery of the through pipe 13 is changed to the through hole 9.10.14.
14 are pressed inside each burring part 11.12.15. After that, each burring part 15 is attached to the through pipe 13.
It is joined by brazing.
貫通穴１０（バーリング部１２が胴部２の外側に向かう
貫通穴）から、突出する貫通パイプ１３の端部は、第１
図に示すように、径が拡大されて、拡大部２０が形成さ

を挿入し、貫通パイプ１３と、ペンドパイプ１つとを接
続する部分である。The end of the through pipe 13 that protrudes from the through hole 10 (the through hole in which the burring part 12 faces the outside of the body part 2) is connected to the first
As shown in the figure, the diameter is enlarged to form an enlarged portion 20. This enlarged portion 20 is a portion into which the end of the vent pipe 19 is inserted and connects the through pipe 13 and one pend pipe.
本実施例の拡大部２０は、胴部２の内側まで伸びる。こ
の結果、拡大部２０は、胴部２の貫通穴１０の内側に、
確実に設けられている。この拡大部２０は、内側から広
げる加工によって形成されている。この結果、胴部２の
貫通穴１０は、貫通穴９に比較して、径が大きくなる。The enlarged portion 20 in this embodiment extends to the inside of the body portion 2 . As a result, the enlarged portion 20 is located inside the through hole 10 of the body portion 2.
It is definitely established. This enlarged portion 20 is formed by expanding it from the inside. As a result, the diameter of the through hole 10 of the body 2 becomes larger than that of the through hole 9.
なお、貫通穴１０のバーリング部１２は、胴部２の外側
に向かうため、拡大部２０の外周面に確実に沿う。この
結果、胴部２と貫通パイプ１３とが確実にシールされ、
貫通穴１０における燃焼ガスの漏れを、確実に防ぐこと

２が、逆の胴部２の内側に向かって設けられていると、
バーリング部１２の内周に、拡大部２０の奥方のテーパ
一部２０ａが位置する結果となり、シール性が低下して
しまうためである。In addition, since the burring part 12 of the through hole 10 is directed toward the outside of the body part 2, it reliably follows the outer circumferential surface of the enlarged part 20. As a result, the body 2 and the through pipe 13 are reliably sealed,
Leakage of combustion gas in the through hole 10 can be reliably prevented. This is, for example, the burring part 1 of the through hole 10.
2 is provided toward the inside of the opposite body part 2,
This is because the tapered portion 20a at the back of the enlarged portion 20 is located on the inner periphery of the burring portion 12, resulting in a decrease in sealing performance.
また、バーリング部１２が、胴部２の外側に向かうため
、フィン３のバーリング部１５と対向することが防がれ
る。このため、バーリング部１２．１５が対向しないこ
とにより、フィン３と胴部２との間の隙間が大きくなる
ことが防がれ、燃焼ガスの吹き抜けが防がれるとともに
、隙間が大きくならない分、主熱交換部６の外形寸法を
小さくできる。Further, since the burring portion 12 faces toward the outside of the body portion 2, it is prevented from facing the burring portion 15 of the fin 3. Therefore, since the burring parts 12 and 15 do not face each other, the gap between the fin 3 and the body part 2 is prevented from becoming large, and combustion gas is prevented from blowing through. The external dimensions of the main heat exchange section 6 can be reduced.
一方、拡大部２０における、ベントパイプ１９との同名
手段は、ろう付けによって成されている。On the other hand, the means having the same name as the vent pipe 19 in the enlarged portion 20 is formed by brazing.

比較して小さくなる。(Effects of Example) Since the enlarged portion 20 is formed inside the through hole 10,
Compared to conventional heat exchangers in which the enlarged portion is formed outside the body, the connection between the through pipe 13 and one pen viar is moved to the inside of the heat exchanger 1. Then, the position of the end of the vent pipe 19 moves to the inside of the heat exchanger 1, and as a result, the external dimension A (see FIG. 3) of the heat exchanger 1 becomes smaller than that of the conventional one.
