本実施例の冷媒凝縮器１の作動を第１図ないし第４図に
基づき説明する。The operation of the refrigerant condenser 1 of this embodiment will be explained based on FIGS. 1 to 4.

の位置関係が容易に決定される。The assembly work of assembling the header 2 to the end portion 41 of the tube portion 4 involves inserting the end portion 41 of each tube portion 4 into each insertion hole 2 of the header 2.
This is done by inserting it into 5. At this time, since each insertion hole 25 of the header 2 is formed at appropriate intervals, the end 41 of each tube part 4 is inserted into each insertion hole 25 of the header 2.
Simply insert each tube section 4 into the header 2.
The positional relationship between the two is easily determined.

およびガイド溝２７に沿って挿入するだけで、ヘッダ２
に対するチューブ部５の位置関係が容易に決定される。In addition, in the assembly work of assembling the header 2 to the end 51 of the tube part 5, the end 51 of the tube part 5 is aligned along the insertion hole 25 and the guide groove 27 of the header 2, so that the tip of the tube part 5 is aligned with the header 2. This is done by inserting it into the header 2 until it contacts the inner wall surface of the side wall 26 on the right side in the figure. For this reason, the end portion 51 of the tube portion 5 is inserted into the insertion hole 25 of the header 2.
Just insert the header 2 along the guide groove 27.
The positional relationship of the tube portion 5 with respect to the tube portion 5 is easily determined.
したがって、デユープ部５の端部５１は、ヘッダ２に対
して位置決めがなされているので、ヘッダ２の所定の位
置から移動することが防がれる。Therefore, since the end portion 51 of the duplex portion 5 is positioned relative to the header 2, it is prevented from moving from a predetermined position on the header 2.

とヘッダ２とのろう付は不良が防がれる。The assembled refrigerant condenser 1 is thus brazed in the furnace. At this time, the end 41 of the tube part 4 is in contact with the wall around the insertion hole 25 of the header 2, thereby preventing the positions of the tube part 4 and the header 2 from shifting. At the same time, since the end portion 51 of the tube portion 5 is in contact with the insertion hole 25 and the guide groove 27 of the header 2, the positions of the tube portion 5 and the header 2 are prevented from shifting. For this reason, brazing prevents the tube part 4.5 and the header 2 from shifting in position, and
This prevents defects in the brazing between the header and the header 2.

に対する位置関係が決定されることによって、自動的に
仕切壁５３のヘッダ２に対する位置関係も決定される。Note that the lower side wall of the end portion 51 of the tube portion 5 is used as a partition wall 53 that partitions the inside of the header 2 into an upper chamber 21 and a lower chamber 22, so that the number of parts can be reduced. I can car. Furthermore, the header 2 at the end 51 of the tube portion 5
By determining the positional relationship with respect to the header 2, the positional relationship of the partition wall 53 with respect to the header 2 is also automatically determined.
すなわち、ヘッダ２の内部を上側の室２１と下側の室２

２どのろう付は不良が防がれる。That is, the inside of the header 2 is divided into an upper chamber 21 and a lower chamber 2.
Since the positional relationship between the partition wall 53 and the header 2 that separates the partition wall 53 and the header 2 is easily determined, brazing prevents the partition wall 53 and the header 2 from shifting in position, This will prevent defects.
